What Is Proof Of Stake?

Posted on by Shipra

A blockchain is a form of Distributed Ledger Technology (DLT) that is highly protected by cryptographic encryption. Information is combined into blocks that are connected to one another to build an immutable chain of information, which serves as proof of the presence of a transaction or any sort of data at any specific instant in time on the blockchain.

Since there is no centralized authority to govern and regulate the system, user consensus is vital to achieving the system’s security and long-term viability. The development of a consensus mechanism that prescribes the rules by which players should play and obey makes it possible to reach a worldwide agreement on the blockchain.

Proof-of-stake is a digital currency consensus technique that offers an alternative to the proof of work employed in Bitcoin. The absence of costly computations and hence a reduced entry hurdle for block generation rewards are the key claimed benefits of proof of stake systems.

What is Proof of Work?

In the early 1990s, Proof of Work (PoW) was used to prevent email spam.

It was a simple concept in which the computers were forced to do some task before sending emails. This task would be easy for anyone sending a legitimate email. However, sending bulk emails would need a large amount of computational power and other resources.

However, Satoshi Nakamoto, the one who developed Bitcoin, was the first to implement this idea for use in a cryptocurrency system in Bitcoin.

Ordering in the Blockchain

The very first block on the blockchain is termed the genesis block and some even call it as block 0 in a PoW blockchain. It is embedded or in better terms, hardcoded into its operating software. This block does not relate to any prior block by convention. New blocks being added to the blockchain network always link to the previous blocks and also contain a copy of the entire, updated ledger.

Use of Resources and Energy

Through a tough competition in which a handful of players (miners) are encouraged to waste computational and power resources in order to develop new legitimate blocks that meet the network’s regulations, Proof of Work algorithms determine who can make changes to the ledger.

 

Then, the nodes (a computer operating the Bitcoin blockchain software) confirm transactions, eliminate double-spending (the malicious act of transferring the very same coins to different beneficiaries), and determine whether suggested blocks should be appended to the blockchain.

 

Miners on the blockchain in a Proof of Work blockchain compete against one another to answer rigorous math equations in a process of complex mathematical problem solving known as hashing in order to generate a new block on the blockchain. These equations are difficult to solve, but the blockchain network should be able to validate the right answer with ease.

Participation

Computational power and resources are used with encryption in Proof of Work to promptly achieve consensus and verify the authenticity and legitimacy of transactions that take place on the blockchain. network

Miners achieve this by working on a series of pseudorandom integer values also known as a hash. This hash, when coupled with a set of data supplied within the block, is processed through cryptographic hashing and this must yield a result that meets the specified requirements.

The successful hash is then published to the network so that the other miners may determine if the answer is correct or not. If it is accurate, the block is uploaded to the blockchain, and the miner receives the block reward.

Earnings and Rewards

The block reward is the cryptocurrency paid to the miner by the blockchain for each complete and approved block by the network.

Cryptocurrencies like Bitcoin, reduce the block reward after a defined number of blocks have been identified. This is done to maintain a deflationary total coin supply on the blockchain network.

What is Proof of Stake?

Proof of Stake is simply a variant of Proof of Work that was created in order to meet its perceived dependence on energy usage as a process of determining blockchain ordering.

Rather than trusting on computers being run by the blockchain miners competing to produce the correct hash, the principle that works behind a Proof of Stake system is that involvement is decided by the amount of coin supply ownership.

The Proof of Stake method selects a participating node (anyone who possesses the coin) to deal with the next transaction on the blockchain using a set of parameters determined by the system.

When a node is chosen, its responsibility is to authenticate  and validate the transaction within the block, and then submit the block to the system for verification.

Ordering in the Blockchain

A Proof of Stake blockchain is very identical to a Proof of Work blockchain network in many ways. This method uses a string of blocks that are aligned in chronological order depending on the order of the transactions.

The genesis block in a Proof of Stake method is embedded into its operating system and is often referred to as block 0. Newer blocks that are created on the blockchain always refer to the previous block and also hold a copy of the entire updated ledger on the blockchain.

It is important to know that in a blockchain developed using the Proof of Stake method there is no contest for who is assigned to contribute new blocks. For this reason, the blocks are usually referred to as “minted” rather than “mined”.

Use of Resources and Energy

Proof of Stake blockchains, unlike Proof of work blockchains, do not select who may propose the blocks simply on processing power and energy use. Proof of Stake proponents frequently touts it as a “more energy efficient” system in which specific nodes are tasked with producing new blocks rather than competing with the other nodes on the blockchain.

Because both Proof of Work mining and Proof of Stake minting require power consumption, both these mining and minting nodes are encouraged to use the cheapest source of energy possible, which is typically generated by renewable energy sources such as hydroelectric power, wind power, or solar rather than greenhouse-emitting natural resources such as coal, etc.

Furthermore, Proof of Stake blockchains necessitate the usage of specialized equipment which are known as the Graphic Processing Units, just like Proof of Work mining equipment known as the Application Specific Integrated Circuits as well as the other computing machines, necessitate the production of resources.

Proof of Stake miners must additionally maintain active internet connections, which necessitates the expenditure of electricity and other recurring cost resources.

Participation

Users who intend to be considered for producing blocks on a PoS blockchain must stake or deposit a particular sum of the blockchain’s cryptocurrency in a unique form of a special contract.

The number of coins invested impacts their chances of being the next block producer. In some circumstances, users that engage in malicious activities may be punished by losing their stake.

Proof of Stake may incorporate various deciding variables in order not to always prefer the wealthier nodes. These can include how long a node has staked their currency as well as pure randomness.

Earnings and Rewards

The block reward in Proof of Stake, like the Proof of Work method, refers to bitcoin granted by the blockchain to the node who submits a valid block.

However, because block selection is determined by currency ownership, exchanges may provide staking services that allow users to stake funds on their account in return for more frequent payment.

Importance of Proof of Stake (POS):

The core database structure for recording transactions in cryptocurrencies such as bitcoin is a decentralized ledger known as the blockchain, which keeps the full transaction history. The term derives from the concept that transactions are grouped into blocks; every block on the blockchain (excluding the first, known as the genesis block) refers to a previous block. Each Bitcoin network node has its own copy of the blockchain, which is synced with other nodes through a peer-to-peer protocol. Any digital currency system must include a method to protect its blockchain against assaults.

 

For example, a malicious user may spend money and then reverse the transaction by broadcasting his own version of the blockchain that does not include the spending transaction; because blockchain security does not depend solely on one single authority, users have no previous knowledge as to which version of the ledger on the blockchain is valid.

 

The security of the Bitcoin-like cryptocurrency networks is based on a proof of work (PoW) mechanism in the manner of block mining. To confirm the legitimacy of the newly mined block, any node that wishes to participate in mining must solve a computationally tough problem known as hash; solutions are awarded to these miners with bitcoins. The method is fair in the respect that if a miner with x percent of total processing power may earn the reward and generate a block with x percent probability. 

A malicious user must accomplish the same challenges as the rest of the Bitcoin blockchain; hence, an assault on Bitcoin will be effective only if the attacker can bring considerable computing resources to force.

The Bitcoin protocol operates in such a way that network security is maintained by physically limited resources: 

  •  special hardware required to conduct calculations, and 
  • electricity required to operate the hardware.

As a result, Bitcoin is wasteful in terms of resources. Bitcoin miners are driven to engage in an arms race to continually deploy additional resources for mining in order to raise their share of rewards. While this results in an assault on Bitcoin prohibitively expensive, the Bitcoin protocol’s environmental unfriendliness has resulted in ideas to construct comparable systems that are far less resource hungry.

Proof of stake (PoS) algorithms are one alternative decentralized ledger implementation that does not rely on expensive calculations for security. Instead of mining power, the likelihood of creating a block and receiving the related reward is proportional to a user’s ownership share in the system. With x probability, an individual stakeholder with x proportion of the total number of currency in circulation produces a new block.

The logic behind proof of stake is as follows: users with the strongest holdings in the blockchain ecosystem have the most interest to keep the network safe from malicious users and attackers, since they would suffer the most losses if the cryptocurrency’s reputation and price declines as a result of the assaults or attacks. An outside attacker would need to acquire the majority of the money to launch a successful attack, which would be extremely expensive for a popular system and would not make any logical sense.

 

Conclusion

The proof of stake model is predicted to grow into a potentially more competitive and peer-to-peer type of crypto-currency on the blockchains than the proof of work methods owing to the removal of dependency on high energy use, resulting in lower asset prices at adequate network security levels.

The Cardano blockchain is openly accessible, the system is decentralized and open-source, and consensus is established by proof of stake. According to the ruling in Solana vs Cardano vs Polkadot can utilize its token, ADA to facilitate peer-to-peer (P2P) transactions. As a third-generation platform, Cardano is an improved version as opposed to Polkadot vs Solana.

Additionally, the blockchain platform seeks to provide financial services to unbanked individuals worldwide. Additionally, one intriguing component of Cardano is the way it uses its ‘eras’ to celebrate historical individuals in computer science and poetry. The goal of the Basho scaling and optimization phase is to provide additional functionality to Cardano. 

What is Polkadot?

June 2021 saw the launch of the open-source Polkadt blockchain. It makes blockchains more accessible and connected by permitting distinct chains to securely communicate and carry out transactions. It makes use of the Layer-1 blockchain known as the Kusama parachain. Over 100 para chains are supported by Kusama, and experts predict that number will continue to rise. As a component in your investment strategy, you can sell and buy DOT in addition to SOL, ADA, and DOT. Users can run customized platforms on top of a global network of personal blockchains with Polkadot, a cryptocurrecny. The Polkadot token (DOT), a cryptocurrency, serves two primary purposes inside the Polkadot blockchain network. 

  • With DOT, owners have the power to shape the protocol’s course. 
  • New DOTs are created by the Polkadot cryptocurrency network, which validates transactions by staking its money.

A Future Based On Metaverse – A Solulab Take

Posted on by Shipra

The Metaverse is a network of three-dimensional virtual environments where users can build their unique avatars and explore them across various platforms and environments. The term was invented by author Neal Stephenson in his 1992 novel Snow Crash, but it gained unexpected popularity when Facebook announced its rebranding as Meta. According to Meta creator Mark Zuckerberg and other enthusiasts of the Metaverse, the ultimate goal is to create a sort of second digital world for everybody to live online.

In an ideal situation, the technology would allow users to feel as if they were physically present at an event, with high-definition, three-dimensional environments accessible via virtual reality eyewear, as well as other avatars you can approach and interact with, and even physical things you can pick up and examine using haptic gloves or game controllers. While such technology may not yet exist—or, at the very least, maybe too expensive for the typical event attendee—several tech businesses and virtual event sites have already begun to develop their own, relatively minimal versions of the Metaverse.

Metaverse and the Future

Metaverse

The impact of globalization on human civilization as a whole is well known. Products from all over the world made their way to practically every corner of the globe, elevating our living level. When virtual worlds work together to build one Metaverse, the same impact, if not greater, may be predicted. Let’s look at how Metaverse can affect many aspects of human life and its future.

Business and Shopping

Traditional shopping poses several problems, which is why shopping online has become so popular. When users purchase online, you don’t have to worry about closing hours or waiting in a huge queue of people to get their needs met. Virtual Reality will soon be available in our everyday browsers, making it easier than ever to check out the things users love. Websites do, however, have limits. Adding all of the items and variants to the website as a company entity isn’t exactly appealing. People don’t expect a website to function as a retail mall, either. Here’s when virtual retailers come in handy.

Virtual Stores

Virtual stores will give customers the precise shopping mall experience, with no time or geographical constraints. Imagine taking a virtual view of a retail mall in China or the United Kingdom while staying at a different location. Furthermore, there will be bespoke digital shop staff in every metaverse shopping mall that can communicate in any language to give customers one-on-one support. With a simple tap of a finger, users will make them appear or disappear.

Users will be able to see in-depth information on how the items were created, where they were manufactured, which materials have been used, how long they’re expected to last, and so on. Users may even test how well the product will perform in various settings and environments. For example, if a user plans to purchase a motorcycle from a showroom in England, they can see how it will perform in their city depending on the roads and traffic! Furthermore, as the amount of data collected each day grows, clever digital assistants will be able to instantaneously give users things that you may enjoy when you visit a certain store. Virtual intelligent assistants, such as Siri and Alexa, will play an increasingly important role in the future.

Advertising

Advertising has always been about viewing rather than an experience, but that is about to change. Today, we are aware that advertisements are everywhere and that most of them are so irritating that we choose to ignore a significant number of them. However, advertising agencies may soon be able to provide viewers with a more personalized advertisement viewing experience, all thanks to the in-depth and comprehensive data that is being collected through gadgets including smartphones, wearables, IOT devices such as the user’s age, purchase history, brands followed on social media, a network of friends, and so on.

Advertisers can even figure out what commercials we enjoy most using technologies like smartwatches that measure our heart rate. Instead of the current advertising network, every advertisement we encounter will be based on who we are!

Users can browse adverts while on the road and be informed about any changes or updates to their favorite product. So, based on where the user is in the Metaverse, everyone will be promptly told about an intriguing product or store which the user may want to check out. Changes that users may make to a product’s appearance, layout, or other attributes will also influence the content and storyline of the advertisement. Furthermore, sponsors will provide users with virtual tickets to significant events like the World Championships or a huge live performance.

Travel and Tourism

Though we would all welcome the opportunity to travel with our family members in the real world, some may believe that real-life tourism might be problematic. First and foremost, it is quite costly. It is impossible to travel to an exotic destination without paying a large sum of money. Then there are the numerous legal processes that must be completed to visit a location outside of your country.

The quantity of the luggage might also cause problems, based on the number of people traveling. Those who find this tiresome may find that Metaverse has a solution for them. Users may go to a virtual travel agency, choose their location, and relax while on vacation! There will be no discernible difference between visiting the location in person and accessing it online.

Entertainment

Users can’t modify the sound system specifically for themselves in the real world while watching a movie in a multiplex. However, certainly, they can participate in the Metaverse! Users may enter any virtual show and customize the screen, sound, and seats to their liking. As a result, each participant in a virtual movie theater will have a unique experience with the same film. Even movies may require your full immersion, and the plot may proceed based on how users engage with the characters. Similarly, users may use their Metaverse avatar to visit any bars, DJ parties, concerts, or live events worldwide.

Office and Work-Life

How many times have you felt exhausted after attending a slew of interviews in various locations? Aspirants put in the effort, time, and money in the hopes of pursuing a profession that they enjoy. This is something that everyone who has ever been unemployed has experienced. There are numerous drawbacks of Physical interviews. One can only travel as far as the railway, air, and financial resources will allow. Yes, anyone can send an email or make a phone call to any company globally, but the responses to such requests are often poor.

Unleashing new experiences in the corporate world

What if one could go to a company’s virtual corporate headquarters in the Metaverse and check if they’re hiring? Users may truly visit offices in the United States or the United Kingdom from the comfort of their homes! Users do not have to squander their valuable time, money, or energy to get interviewed by the world’s most prestigious firms. Even if a person is recruited by a firm located in another part of the globe, one wouldn’t be forced to sell his fortune to obtain the work permit visa, tickets, or other necessary documents. Users may work from the comfort of home by logging into the metaverse workplace. The boss may be on the other side of the globe, but with a near-lifelike 3D avatar, he can sit next to the staff and coach them through their tasks.

In other words, the Metaverse may soon become the one site of convergence for all workplaces. As a result, there will be relatively little need for actual buildings or office structures in the outer world. Consider how much money, space, and personnel humans could save!

Conclusion

Whether we want it or not, we must face the fact that today’s life is somewhat computer-driven with the influence of significant upheaval, even our perspective of reality shifts. We cannot imagine a world lacking social media platforms like Facebook, Instagram, and Twitter nowadays!

Consider a world without the internet. How about one that isn’t based on computers? We really can’t imagine anything else, can we?

Technology has had such an influence on mankind. To borrow a phrase from Marc Andreessen, technology is a magical box. It’s up to us to make the most of the opportunity. With its great possibilities, Metaverse is the future and might play a significant part in human existence and lifestyle. Like all of its brilliant predecessors, it hopes it will make us wiser, happier, and connected.

How to Build an App on Cardano?

Posted on by Shipra

Cardano is a next-gen blockchain platform created by Charles Hoskinson in the year 2015. He was one of the early developers of Ethereum and the co-founder of BitShares. One of the most defining features of Cardano is its focus on completely transparent research as well as development based on evidence. It is truly the first blockchain project to be peer-reviewed. Charles Hoskinson described Cardano as the third-generation blockchain with Bitcoin and Ethereum as the first & second-generation blockchain. The platform happens to be an excellent blockchain platform for building smart contracts, websites, and apps with any kind of scalability problems.

Building an App on Cardano

Now, it is clear that Cardano serves as a very good and effective blockchain platform for building apps. So, let us dive a bit deep into the topic to understand how to build an app on Cardano.

Step 1 - Defining the Scope of the App

At the time when you have planned to build an app on Cardano, it is of immense importance to start with defining the scope or concept of the project. It is ideal to be specific about the exact product to be created, which makes the idea behind the project quite clear. Here are a few important questions to ask that help define the scope of the project and make the developmental tasks easier during the proceedings.

  • Does the app match the present trends?
  • What problem the app solves, and what benefits it offers to the users?
  • What is the app’s potential in terms of market & audience size, and future demand?
  • Who are the competitors?

Answering these questions plays a significant role in appropriately defining the scope or concept of the project.

Step 2 - Defining Business Goals, KPIs, and Monetization Models

Once the scope of the project is defined, it is essential to start defining the business goals. If the app is for commercial use, then it is important to calculate the methods of monetization and the income that it can bring in the short, medium, as well as long run. This, in turn, will play a crucial role in planning the budget of development, providing detailed information regarding the choice of optimum monetization model, and determining the KPIs. At this stage of building an app on Cardano, here are a few pointers to consider.

  • The way of revenue generation from the app.
  • The overall budget requirement for app design and development.
  • Presence of any growth springboard like the launch of a new blockchain, market or world events, the failure of competitors, etc.
  • Association of any potential risks.

Keeping these pointers in mind makes sure that the developmental tasks are carried out smoothly without any kind of interruption.

Step 3 - Choosing the Appropriate Tools and Software

It is the most important step of building an app on Cardano. It is extremely important to select the most appropriate tools and software before building the app. Choosing advanced tools and technologies makes sure that the best results can be obtained. In this regard, it would certainly be a very good idea to seek the help of a professional blockchain app development company to get the best possible results. It is recommended to choose a development company with adequate skills, vast experience, in-depth knowledge, a dedicated & comprehensive team, a comprehensive approach to app development, and a business-oriented approach.

Step 4 - Development of the App

This stage involves the building of the app. The developers perform their duties by implementing the design in the right way and the functionality in software code by the use of standard tools for development as well as some special solutions from Cardano such as Plutus, Playground, Glow, Marlowe, KEVM devnet, and IELE devnet.

Step 5 - Launching the App

It is the final stage or step where the app is launched. After designing and developing, the app is tested before its final implementation. Ultimately, the created apps need to be deployed on the Cardano blockchain and added to different listings.

Benefits of Building an App on Cardano

After reading through, you have a clear idea about the process of building an app on Cardano. Now, let us understand the benefits of building an app on Cardano.

Ouroboros Consensus Mechanism

The main benefit of building an app on Cardano is the Ouroboros consensus algorithm. It is a highly secure version of Proof-of-stake, where the transactions are not checked by every node as in the case of Proof-of-work, but they are checked by a selected group of network participants referred to as the slot leaders.

Dual-Tier Network Architecture

Another benefit of using Cardano to build apps is the separation of the blockchain into two related but fairly independent tiers.

  1. Cardano Settlement Layer or CSL is the first tier that is responsible for operation and processing transactions for the Cardano wallets.
  2. Cardano Computation Layer or CCL is the second tier that is responsible for the operation and calculation of apps.

This separation allows making significant changes to the blockchain without forking.

Interoperability

This feature allows different non-homogeneous shards and blockchains to work together. Moreover, it allows the creation of apps that are very closely linked to one another but still remain independent.

Scalability

Scalability is another major benefit of building apps on Cardano. With Ouroboros and sidechain technology, Cardano has the potential to process a trillion transactions per second. This high potential of scaling enables Cardano to be the basis for the development of any level of apps.

Transparency

Another major benefit offered by Cardano is complete transparency and its decentralized nature. All the research is public, the software’s source code is open, and the technical processes are audited on a regular basis. Moreover, the results are available publicly, thereby enhancing transparency.

Legitimacy

Legitimacy is one more important benefit of building apps on Cardano, where the project team’s wishes are balanced with those of the centralized authorities as well as the decentralized community. Developing an app on Cardano makes sure that it complies with all the necessary laws, rules, and regulations set by authorities.

Conclusion

Building apps on the Cardano blockchain is still in its budding phase. Slowly and steadily, we have seen a rise in using the Cardano platform for developing apps. It is true that the benefits offered by Cardano can be appropriately leveraged to create highly useful as well as functional apps. The scope of building apps on Cardano is huge, with a wide array of opportunities. So, we have to wait and see what the future has in store for app development on Cardano.

Building Games on Blockchain: A Starting Point

Posted on by Shipra

Different degrees of decentralization are used in blockchain games as part of their gameplay. They enable true ownership of digital objects via game coding and smart contracts.
Interoperability across games, player-based economies, and monetization gaming methods is also enabled by blockchain technology.


The emergence of blockchain games has flipped the gaming industry on its head by making players, rather than producers, the primary financial decision-makers.
P2E, or Play-to-earn crypto gaming, is a growing trend that should not be ignored.

Technological process and cost of blockchain game development.

Blockchain game creation will be a steep learning curve if you’ve never dealt with blockchain technology before. However, if you comprehend the technology and put it to use, you will realize how it may open up new options for your firm.


So, how does one go about creating a blockchain-based game?

Investigate blockchain technology in detail and consider what it may add to your game.

You’ll need to learn how the public blockchain works and what its benefits and drawbacks are, as well as how decentralization affects players’ experiences. Learn about blockchain consensus processes, hash functions, and cryptography as well.

Explore current blockchain systems and choose the best one for your needs.

The Ethereum blockchain serves as the foundation for the majority of crypto games. Aside from reading the instructions for this platform, it is also strongly advised that you do some research on how effectively other games are operating on this blockchain.
However, it is also worthwhile to learn about other blockchain systems such as Flow, Echo, EOS, Solana, and WAX. Perhaps one of these will be ideal for your next game.

Acquire knowledge of data structures, databases, and programming languages.

Many developers are acquainted with programming languages such as C++, Python, and JavaScript, but Solidity and Cadence—languages built particularly for blockchain —may be unfamiliar. When it comes to databases, make sure to learn more about BigchainDB, MongoDB, LevelDB, and CouchDB.

Improve your smart contract creation abilities.

Smart contracts are one of the most important components of any blockchain application, so a blockchain game developer must comprehend the idea as well as know how to design, test, and deploy them.

Creating a hack-free environment for players

Although blockchain provides greater security, no technology is completely impenetrable. As a result, blockchain game creators must work hard to build a genuinely hack-resistant environment. They should assess and remove possible hazards like theft of private keys, code exploitation, and illegal modifications to blocks.

Ensuring the security of transactions

Developers must also consider the security of transaction endpoints like wallets and payment systems. Even if the blockchain is completely safe, a compromised wallet may cause major issues for both game businesses and gamers.

Hire a professional blockchain developer.

You have another choice as a video game creator: hire a professional blockchain developer. A team like this will provide advice on all elements of blockchain technology deployment and will create a gaming platform that is entirely immune to interruptions and DDoS assaults.

Determining the cost of game development

When it comes to the cost of producing blockchain games, the figures might vary greatly. The cost is typically determined by the complexity and design of the future game, the technologies used, the number of app versions and platforms (Android, iOS, PC, and so on), and even the geographic location. Prices typically begin around $30,000.

Is it possible to make money from playing blockchain games?

The use of cryptocurrencies for in-platform payments, as well as the use of NFTs, are two features that set blockchain games apart.they enable users to possess unique assets that may be exchanged with other players inside the same game or moved across platforms, NFTs are an important step forward. And, much like in real-world economies, you may profit from markets inside blockchain games.


The most devoted gamers may receive monetary prizes for their efforts, while those with creative talents can develop and sell valuable objects. The opportunity is enormous, and game makers are just getting started.
Some people enter the gaming sector just to become investors, while others make it their full-time profession.

How do blockchain games assist players and developers?

To safeguard crypto token transactions, blockchain systems use incredibly sophisticated data encryption technologies such as the private key-public key pair. These data encryption algorithms are difficult to penetrate with today’s computer technologies.


Aside from that, hackers will be unable to damage a decentralized blockchain network since there is no one server to attack. Nodes share the maintenance of distributed databases, and each node has full access to the database.


Hackers are unable to erase or change previous transactions on the blockchain, nor can they launch a ‘Distributed Denial of Service’ (DDoS) assault against these networks. Blockchain networks employ ‘Proof of Work‘ (POW) or other consensus mechanisms to ensure network security.


When you construct your game on the blockchain, you have a safe environment as a game entrepreneur or developer.

How can blockchain games assist players?

  • Players get real-world advantages from the game’s rewards as well as by selling their virtual assets on decentralised exchanges.
  • Players are not reliant on pricing and rules imposed by developers when they trade products on a decentralised exchange.
  • The quality of the game has improved for the players.

What are the advantages of blockchain games for developers?

  • Game developers now have new options to monetize gaming.
  • Developers might entice more gamers by offering additional cash incentives.
  • Developers may bypass the intermediaries (external digital marketplaces).

Why should you try crypto games?

Players’ desire to monetise their gaming talents and the time they spend in front of a screen is nothing new.


Blockchain gaming opens up dozens of new possibilities. You will not only be able to earn money in transparent and fair virtual economies, but you will also have genuine ownership of game assets and will be effectively a stakeholder by contributing to a community-driven ecosystem (DAO) and having your opinion heard on game-related matters.


None of this was conceivable in conventional, centralised gaming, and as more crypto games arise, the greater the motivation for more people to participate in more equitable and transparent virtual experiences.

Top Blockchain Games to Look Out For

Gala

Gala Games, a blockchain gaming platform, and C2 Ventures, a crypto investment firm, have formed a $100 million fund to invest in blockchain-based P2E games, metaverse settings, and other ventures.


Gala Games claims that the fund will invest in game creators and decentralised gaming ventures.
Ciara Sun, the former head of blockchain investments at Huobi Global, founded C2 Ventures, a crypto investment firm.


Gala Games announced the appointment of Huobi Global as a partner in an advisory capacity for initiatives including marketing and Web 3.0 growth. Furthermore, the cryptocurrency exchange will work with teams to offer future tokens.


According to e-sports analytics company Newszoo, global gaming revenue is predicted to exceed $200 billion by 2024.

Sandbox

In this virtual realm, known as the metaverse, players may own land, create, play, and engage in virtual adventures. You may monetise the experiences you create inside the metaverse by owning a sandbox plot of virtual land, which might be an attractive hobby for artists or tiny devs who aren’t comfortable with other gaming engines.


It is possible to use the SAND token to purchase and sell all Sandbox features, and this helps to keep expanding this metaverse in the long run. In addition to acquiring and selling virtual property, players may trade NFTs, which can be used to customize their avatar’s appearance.


To compete with Minecraft and Roblox, Sandbox has developed a robust community of users who can participate and share ideas in order to spur more creativity on the platform.

Axie Infinity

Axie Infinity is the most popular blockchain game in the Philippines, with many younger folks abandoning their jobs to earn $2k monthly.


Players in Axie Infinity may earn $SLP by playing the game. While AXS is the governance token, it is the most analogous to holding shares in a company. These tokens let holders vote on and propose modifications to the Axie Infinity platform.

Lightnite

Lightnite, created by the same company that created the Bitcoin arcade game portal Satoshi’s Games, has been described as a Fortnite-like battle royale game. This online multiplayer game pays players in Bitcoin for shooting other players, and all microtransactions are enabled by the Lightning Network.


Players who master the game and shoot more opponents have a better chance of earning more Bitcoin. Players who are shot, on the other hand, are fined and lose Bitcoins. Lightnite’s. The Elixir Marketplace platform allows all in-game assets to be tokenized and swapped.

Decentraland (MANA)

Decentraland is an application based on Ethereum aimed at encouraging a worldwide network of users to manage a shared virtual environment.


Decentraland users may explore, interact, and play games in this virtual world. All this is possible while buying and selling digital real estate. Because of the platform’s growth, users may now utilise interactive applications, in-world payments, and peer-to-peer interaction.

ZED RUN

A horse is represented by NFTs in the blockchain game ZED RUN. Each horse has its own set of strengths. You may end up with a champion stallion, or your horse may be better suited to being a stud.

Conclusion

We have seen many advancements in gaming as a result of blockchain technology. P2E models, or play-to-earn models, NFTs, and real-world ownership of in-game objects are all examples of decentralisation.There is still a long way to go before blockchain games become mainstream.

Hashgraph vs Blockchain- A Detailed Overview

Posted on by Shipra

Hashgraph vs Blockchain

For more than ten years, blockchain technology has proven reliable and has been utilized in several specialized fields. While the idea of a chain of cryptographically secure blocks was initially put out in the early 1990s, it wasn’t until 2008 with the introduction of Bitcoin that blockchain technology gained widespread attention. It is anticipated that worldwide expenditure on Blockchain-based solutions is projected to climb from $4.5 billion in 2020 to around $19 billion in 2024. The potential of this technology is so immense that its relevance has expanded to practically every area; whether it is Blockchain in healthcare or agriculture.

Hedera Hashgraph, on the other hand, made its debut in the IT world nine years after Blockchain. Given how quickly and efficiently technology may presently evolve, it would be misleading to say that one technology is more developed than another despite this time disparity. The amount of continuous work put into the development is all that matters. 

Will blockchains be replaced by hashgraphs then? Let’s examine it in more detail by contrasting Hashgraph vs Blockchain detail.

What is a Distributed Ledger Database?

A distributed ledger database is a decentralized database system that is dispersed among several network nodes or participants. It is sometimes referred to as distributed ledger technology (DLT). It makes it possible for everyone to obtain a copy of the database and come to an agreement on the ledger’s current status, facilitating safe and open record-keeping.

With the use of cryptographic techniques, this strategy increases security, reduces fraud, and promotes transparency. Distributed ledger databases cut expenses and simplify procedures by doing away with the need for middlemen. 

Although Hedera Hashgraph and Blockchain are well-known examples of distributed ledger databases, other technologies also provide unique features and consensus procedures.

Distributed ledger databases, in general, offer the framework for developing decentralized applications and systems, transforming markets by permitting dependable and effective peer-to-peer interchange of data.

Essential Principles of DLTs

Here are some of the essential principles of Distributed Ledger Technology:

  • Decentralization: DLTs disperse control over a network of nodes (computers), as opposed to conventional ledgers that are controlled by a single entity. Because every node has a copy of the ledger, there isn’t a single point of failure or control.
  • Transparency and Immutability: DLT transactions are both transparent and unchangeable when they are recorded. Because it keeps hacking and revisionism at bay, its immutability is essential to security and trust.
  • Consensus Mechanisms: To verify transactions and maintain the ledger across all nodes, DLTs utilize consensus methods. To attain consensus across nodes, protocols such as Delegated Byzantine Fault Tolerance (dBFT), Proof of Stake (PoS), and Proof of Work (PoW) are utilized.

Types of DLTs

Various types of DLTs are as follows:

  • Public DLTs: These are accessible to all users and allow them to join and exit the network anonymously. Among the subset of DLTs known as public blockchains are Ethereum and Bitcoin.
  • Private DLTs: Usually utilized by corporations for internal procedures, they are limited to certain members. Although they come at the expense of decentralization, they provide more control and quicker transaction times.
  • Consortium DLTs: Combined elements of public and private DLTs, administered by a consortium of organizations. They achieve a balance between decentralization and control.

Now, that you have understood the basics of distributed ledger technology, let’s get to know what is Blockchain and Hashraph in brief!

Overview of Blockchain Technology

Blockchain technology has been rather popular in the last several years, especially in the financial industry. It has advanced to an unparalleled degree to become more user-friendly and accessible since its launch in 2008. But what is it exactly?

Thus, as the name implies, a blockchain is a network of blocks made up of systems connected to one another via “nodes” that resemble chains. Transactional records are distributed and maintained by this structure throughout the whole network of systems that make up the Blockchain.

The fact that this distributed ledger technology is extremely safe and makes data manipulation nearly impossible is one of the factors contributing to its popularity. The owners’ digital signature is required to confirm each transaction, helping to ensure its authenticity and guarding against tampering. The finest thing is that no one can tamper with the records, even if everyone can view them.

How Is Blockchain Technology Operational?

When considering how Blockchain is changing the digital landscape, it makes sense that this technology is advancing so rapidly. But one question can cross your mind: just how does blockchain technology operate?

Given the optimistic outlook for Blockchain in the business sector, it is imperative that this technology be made more understandable. So let’s have a little conversation on how Blockchain functions.

Thus, the main elements of blockchain are the following three crucial ones:

  • Cryptographic keys
  • Peer-to-peer (P2P) networks 
  • Virtual computing systems that store and keep track of transactional data.

There are two different kinds of cryptography keys: public and private. This pair of keys is held by every member in a blockchain system and is primarily utilized to create a safe and distinct reference for digital identities.

The most important aspect of transactions taking place in a Blockchain system is the safe identity that is generated with these keys. Because of this, the significance of public and private keys in facilitating an effective transaction between two parties cannot be overstated.

You may now be asking how digital signatures fit into the Blockchain. In the realm of crypto, the distinct identity you create with the cryptographic keys is referred to as a “digital signature.” The P2P network becomes subject to this digital signature. This digital signature is used by a large, sufficiently powerful group of people to reach an agreement on transactions and other relevant matters. Following authorization, a transaction between two parties connected to the same network is successfully completed by the use of a mathematical verification procedure.

Now, let’s get into what is Hedera Hashgraph in more detail!

What is Hashgraph?

Even though Hashgraph has only been around for five and a half years, its partnerships with several IT behemoths, like IBM and Swirlds, demonstrate how remarkable it is.

Hashgraph is yet another kind of DLT and consensus method that was developed as a substitute for Blockchain. However, the main goal of this technology was supposed to be to overcome the problems that Blockchain has encountered and continues to encounter.

Hashgraph was created by Hedera, a business, to offer a quicker, safer, and more effective way to come to a consensus in a decentralized network. This technology stores and manages data using the Directed Acyclic Graph (DAG) structure. In addition, it swiftly and effectively achieves mutual consensus between networked nodes by combining voting and gossip processes. As a matter of fact, a number of experts have observed that Hashgraph is able to perform thousands of transactions per second and is more secure than standard Blockchain technology.

How Is Hashgraph Technology Operational?

Hashgraph is a distributed ledger technology that uses a directed acyclic graph (DAG) and a “gossip about gossip” protocol to achieve fast, secure, and fair consensus. Nodes randomly share information with each other, and each exchange incorporates cryptographic hashes of previous events into a new event. This structure allows rapid synchronization of information across the network. Hashgraph employs virtual voting, where nodes independently calculate votes based on the Hashgraph’s history, eliminating the need for actual vote transmission. Nodes then determine the consensus order and timestamp of transactions through a series of virtual votes over multiple rounds.

Hashgraph is Byzantine Fault Tolerant (BFT), capable of reaching consensus even with some malicious nodes, ensuring security. Its gossip protocol and virtual voting mechanism enable efficient consensus with less computational effort than traditional blockchains. The consensus timestamp method ensures fair transaction ordering, making Hashgraph suitable for applications needing high throughput and fairness.

Difference Between Hedera Hashgraph and Blockchain

Here are some key differences between Hedera Hashgraph vs Blockchain Technology:

  • Approach

The primary difference between Hashgraph and blockchain lies in their structural approach. Blockchain organizes data into linear blocks appended sequentially, which works well but has limitations. In contrast, Hashgraph employs a directed acyclic graph (DAG) for storing and accessing information. Despite these differences, both DLTs ensure decentralization by maintaining copies of the ledger across all nodes.

  • Security

Both blockchain and Hashgraph provide robust security measures. Blockchain uses cryptographic methods to secure stored and transmitted data, making the digital blocks tamper-proof. Any attempt to alter the data invalidates the signature, alerting nodes to possible breaches. Hashgraph utilizes Asynchronous Byzantine Fault Tolerance (aBFT) to protect the network from malicious actors, ensuring that recorded events remain unaltered. Unlike blockchain, Hedera Hashgraph’s consensus algorithm avoids a leader-based format, protecting the network from DDoS attacks.

  • Consensus Algorithm

Blockchain employs various consensus algorithms, including Proof-of-Work, Proof-of-Stake, and delegated Byzantine Fault Tolerance, depending on the platform or cryptocurrency. On the other hand, Hashgraph, particularly Hedera Hashgraph, uses virtual voting to achieve network consensus. The Hedera Consensus algorithm, intrinsic to Hashgraph, offers unique advantages through its detailed approach.

  • Speed

Hashgraph significantly outpaces blockchain in transaction speed. While blockchains like Bitcoin and Ethereum handle between 100 to 10,000 transactions per second, Hashgraph theoretically supports up to 500,000 transactions per second. This speed advantage is due to Hashgraph’s Gossip protocol, which requires less information to be propagated as more events occur.

  • Fairness

In blockchain systems, miners have considerable influence over transaction processing, leading to potential unfairness. Hashgraph addresses this by random node allocation and consensus timestamping, ensuring transaction order does not favor any individual.

  • Efficiency

Hashgraph is more efficient than blockchain due to its event-based approach, eliminating the issues of simultaneous block mining and discarded blocks. This results in a more streamlined and efficient network operation compared to blockchain’s block-based system.

  • Adoption and Development Stage

Blockchain enjoys a higher adoption rate and a more advanced development stage, being a decade old and benefitting from early market entry. Technologies like Ethereum have introduced smart contracts and dApps, enhancing blockchain’s utility. In contrast, Hashgraph, especially Hedera Hashgraph, is newer and less widely adopted. Though currently used by over 300 companies, its adoption rate still lags behind that of blockchain technologies.

DAG: Another Take on Distributed Ledgers

Directed Acyclic Graphs (DAGs) represent an innovative approach to distributed ledger technology (DLT). Unlike traditional blockchain, which structures data in linear, sequential blocks, DAGs organize data in a graph format where nodes are connected without forming cycles. This architecture allows for more flexible and scalable data management, making DAGs a compelling alternative in the realm of distributed ledgers.

Structure and Operation

In a DAG-based ledger, each transaction or event is recorded as a node in the graph. These nodes are connected to multiple previous nodes, rather than to a single preceding block. This structure results in a web of interconnected transactions that can be processed concurrently, enhancing efficiency.

1. Transactions as Nodes: Every transaction is a vertex in the graph. To add a new transaction, it must reference one or more previous transactions (parents).

2. No Cycles: The acyclic nature ensures there are no loops, meaning you cannot start at one node and eventually loop back to it. This prevents issues like double spending and ensures the integrity of the ledger.

3. Concurrency: Multiple transactions can be added simultaneously since they don’t need to wait for a block to be mined. This parallelism increases the throughput of the network.

Consensus in DAGs

Consensus mechanisms in DAGs differ significantly from those in blockchain systems. Rather than relying on a single chain of blocks agreed upon by all nodes, DAGs employ a more decentralized approach where each node independently verifies and adds transactions.

1. Gossip Protocol: Information about transactions spreads rapidly across the network through a gossip protocol, where each node randomly shares data with other nodes.

2. Virtual Voting: Instead of actual votes being cast, nodes infer the state of the network by analyzing the structure of the DAG. They use the history of connections (who referenced whom) to deduce consensus.

3. Transaction Confirmation: Transactions are confirmed based on their references. If a transaction is indirectly referenced by many future transactions, it is considered more secure and confirmed.

Security and Robustness

DAG-based systems offer robust security features. The interconnected nature of the graph makes it difficult for malicious actors to alter the ledger without being detected.

1. Asynchronous Byzantine Fault Tolerance (aBFT): Many DAG systems, like Hedera Hashgraph, utilize aBFT to secure the network. This ensures that consensus can be reached even if some nodes act maliciously.

2. Tamper-Proof: Once a transaction is included and referenced by subsequent transactions, altering it would require changing all subsequent transactions, which is computationally infeasible.

3. No Centralization Risks: Unlike blockchain systems that might centralize around mining pools or validators, DAGs distribute validation work across all participating nodes, enhancing decentralization.

Use Cases of Blockchain

Blockchain technology has a wide range of applications due to its decentralized, secure, and transparent nature. Here are some key use cases:

1. Financial Services

Cryptocurrencies: The most well-known use of blockchain technology is in cryptocurrencies like Bitcoin and Ethereum. Blockchain provides a decentralized, transparent, and secure ledger for recording transactions, ensuring trust without the need for intermediaries.

Cross-border Payments: Blockchain can streamline cross-border transactions by reducing the need for intermediaries, lowering costs, and speeding up processing times. Ripple is an example of a blockchain-based solution aimed at facilitating international payments.

Smart Contracts: Platforms like Ethereum allow for the creation of smart contracts, which are self-executing contracts with the terms directly written into code. These contracts automatically enforce and execute the terms of agreements when predefined conditions are met.

Related: Blockchain in Trade Finance

2. Supply Chain Management

Traceability: Blockchain can enhance transparency and traceability in supply chains. Companies like IBM and Walmart are using blockchain to track the origin and journey of products from suppliers to consumers, ensuring authenticity and quality control.

Anti-counterfeiting: By recording every transaction and movement of goods on an immutable ledger, blockchain helps prevent counterfeiting and fraud, especially in industries like pharmaceuticals, luxury goods, and electronics.

3. Voting Systems

Secure Voting: Blockchain can create tamper-proof voting systems, ensuring the integrity and transparency of elections. Each vote can be recorded on the blockchain, making it nearly impossible to alter the results once they are submitted.

4. Healthcare

Medical Records: Blockchain can securely store and manage medical records, providing patients and healthcare providers with a unified and tamper-proof health history. This enhances data sharing while protecting patient privacy.

Drug Traceability: Blockchain can track the production and distribution of pharmaceutical drugs, helping to prevent counterfeit drugs and ensuring the authenticity of medications.

Use Cases of Hashgraph

  • Decentralized Content Platforms: Enables the creation of platforms where users can share and monetize their content directly, benefiting from the network’s speed and security, and reducing reliance on intermediaries.

Will Blockchain Be Replaced by Hashgraph?

We do not currently think that Hashgraph will take the place of blockchain. However, there are a number of advantages to adopting Hashgraph versus blockchain technology. The current wave of blockchain acceptance is just growing, and businesses are now eager to begin utilizing blockchain thanks to the usage of private blockchains.

Blockchain technology is already being used by a lot of businesses, and we think this is only the beginning of a new age. However, Hedera Hashgraph may stand alone and become more well-liked without taking the place of any other technology.

Even while blockchain has a lot of problems, they aren’t significant enough to make the technology less popular.

Consensus Mechanism – A Simplistic Explanation

Posted on by Shipra

Blockchain technology has been on the rise over the past few years which is precisely the reason why blockchain has become a very common term for us. But have you heard about the consensus mechanism? Although blockchain is a commonly known term, the consensus mechanism is not known by many. Now, let us delve a bit deeper into the topic to understand what consensus mechanism is and what it is all about.

Concept of Consensus Mechanism

Consensus mechanism refers to a mechanism that is tolerant to faults and is used in blockchain systems for the purpose of achieving the required agreement on a single data value or on a single state of the network among the multi-agent systems or distributed processes, like in case of cryptocurrencies. There are a number of different types of consensus mechanisms which are basically multiple programming used in order to achieve consensus as well as trust or users across a network of computers, thereby ensuring secure as well as genuine crypto transactions across the decentralized blockchain technology. Consensus in a distributed ledger, means to ensure that a total of 51 percent of the entire network nodes agree to the present network’s condition. This, in turn, ensures three things.

  1. It plays a significant role in reducing cyber attacks by 51 percent since the hackers need to get control of at least 51 percent of the network to launch attacks.
  2. These mechanisms are tolerant to faults, thereby enabling continuous functioning of the operating system even at the time of failure of one or two components.
  3. The consensus mechanism also helps in maintaining the records of each of the transactions.

Different Types of Consensus Mechanisms

After getting an idea about consensus, let us learn its different types. Consensus mechanisms in blockchain can be classified into 8 types that are discussed below.

Proof of Work

Proof of Work or PoW process is also referred to as mining and the miners are referred to as nodes. The miners are the ones who find an appropriate solution to different complicated mathematical puzzles that need extensive computational power. To do the same, miners make use of different mining methods such as CPU mining, GPU mining, mining pools, FPGA mining, ASIC mining, and a number of others. After solving the mathematical puzzles, the miners receive a block as a reward if they happen to be the first one to find the solution. In addition to this, the mathematical puzzles can only be solved with the trial and error method. It is precisely the reason as to why the miners need an increasing amount of computational power for the quick finding of the solutions.

The level of difficulty for the mathematical puzzles tends to vary as per the speed at which the blocks are being mined. In the case of quick creation of the blocks, the puzzles would get much more difficult and vice versa. Hence, new blocks are required to be created within a specific frame of time for the purpose of carefully adjusting the level of difficulty of the mathematical puzzles. A number of well-known cryptocurrencies such as Bitcoin make use of the Proof of Work process. However, the Proof of Work consensus mechanism eats up resources at a very high rate, thereby making the process quite an expensive one.

Proof of Stake

Proof of Stake or PoS makes use of a randomized process for the purpose of figuring out the one to get a chance to produce the next block. The users of blockchain can lock up their tokens for a specific period of time in order to become a validator. After becoming a validator, the users are able to produce blocks. The validators can also be chosen according to the design of the blockchain. Usually, the user who possesses the largest stake or coins for the longest span of time has much better odds for the creation of a new block.

The validators get rewards for their work in terms of the entire transaction fees or a part of it for each of the transactions carried out by them in the block so created. On the other hand, the validators might receive a certain amount of coins as a result of inflation. With this approach, the Proof of Stake mechanism provides incentives to validators in order to maintain the blockchain network. Proof of Stake happens to be much more energy efficient as compared to other blockchain consensus mechanisms such as Proof of Work.

Delegated Proof of Stake

Delegated Proof of Stake or DPoS is a process in which the users can stake their coins and vote for a specific number of delegates. The weight of the vote of a user depends upon their stake. For example, if a user stakes 20 coins for a delegate and another user stakes 2, then the first user’s vote will have more weight compared to that of the second one. The delegate that receives the maximum number of votes gets a chance to create new blocks.

The delegates are rewarded with transaction fees or a certain number of coins very similar to other blockchain consensus mechanisms like Proof of Stake. Delegated Proof of Stake happens to be one of the speediest blockchain consensus mechanisms. This mechanism has the potential to deal with a higher number of transactions as compared to the Proof of Work mechanism. As a result of its voting system based on the weights of stake, Delegated Proof of Stake is very often considered as a digital democracy.

Proof of Capacity

Proof of Capacity or PoC is a method where solutions to complicated mathematical puzzles are stored in digital storage like hard disks. The entire process is referred to as plotting. Once a storage device is filled with the solutions for the mathematical puzzles, the users are able to make use of the same for the creation of blocks. The users who are quickest in finding the solutions to the puzzles get a chance to create a new block. Therefore, the users who possess the highest storage capacity will have a higher probability of creating a new block.

Proof of Identity

Proof of Identity mechanism compares the private key of a user with an authorized identity. This mechanism is basically a piece of cryptographic evidence for a private key of the user that is cryptographically attached to a particular transaction. Any of the identified users from a blockchain network is able to produce a data block that can be presented to anyone present in the blockchain network. The mechanism of Proof of Identity makes sure that the integrity and authenticity of the created data are maintained. For instance, the Proof of Identity mechanism can be used for the purpose of verifying the identity of citizens in a city.

Proof of Elapsed Time

The mechanism of Proof of Elapsed Time randomly and fairly selects the creator of a new block depending on the time of total waiting period spent by them. In order to do the same, this mechanism provides a waiting time for every user which is completely random. Then, the user whose wait time is completed first will create a new block. This type of consensus mechanism is suitable at the time when the system has the ability to verify that no users are able to run multiple nodes and the wait time is genuinely random.

Proof of Activity

The Proof of Activity mechanism is basically a combination of Proof of Work and Proof of Stake. In this mechanism, the miners try to find the appropriate solution to a mathematical puzzle and earn their reward. In this mechanism, the blocks created are quite simple templates that come with the mining reward addresses as well as the header information. The header information is then used to select a random group of validators for the purpose of signing a block. The validators who possess larger stakes will have greater odds of being chosen to sign a new block. After the selected validators sign a new block, it becomes a part of the blockchain network. In case any of the blocks remains unsigned by some validators, it gets discarded and a new block is made use of. In the process, the generated network fees are divided among the miners and the validators who emerged as winners.

Proof of Authority

The Proof of Authority mechanism happens to be a modified version of the Proof of Stake mechanism. In the mechanism, the identities of validators in the blockchain network are at stake. In this situation, the identity happens to be the correspondence between the personal identification of the validators and their official documentation so that they can properly help verify their identity. Now, on the blockchain network, these validators risk their reputation. In the Proof of Authority mechanism, the nodes that become validators are the only ones who are allowed to create new blocks. The validators whose identity is at stake are incentivized to preserve as well as secure the blockchain network. Moreover, the total number of validators is also quite fairly small in this regard, which is up to 25.

After reading through, one can have a clear understanding of the consensus mechanism and its major types that exist in the blockchain. Also, it needs to be kept in mind that the goals of each of the consensus mechanisms are similar.

Conclusion

In spite of having similar goals, different types of blockchain consensus mechanisms make sure that there is consensus with a differing approach. There does not exist a single reliable consensus mechanism yet but the ones that exist have evolved over time in the appropriate manner to properly meet the requirements of blockchain technology. In addition to this, predicting the exact type of blockchain consensus mechanism which will be highly useful and most popular in the long run in the time to come is certainly complex. It is because of the fact that the underlying technology is quite a new one. Therefore, the business leaders who are planning to implement blockchain technology into their business should be well versed with the different types of blockchain consensus mechanisms in order to get the best out of the technology.

What Are Blockchain Nodes and How Do They Work?

Posted on by Shipra

Blockchain Nodes

Blockchain technology has grown in popularity in recent years because of its decentralization, security, and transparency. A node is a key component of a computer network, helping to ensure the network’s integrity and decentralization.

As a blockchain newbie, you must comprehend the intricacies of the network in order to have an in-depth knowledge of blockchain ecosystems. Any blockchain network would collapse without nodes; they are very crucial.

In this blog, we will define a blockchain network, a blockchain node, how to deploy a node, and why you may want a blockchain node provider.

What is a Node in Blockchain?

For an understanding of what are nodes in blockchain, you have to first know how a blockchain network operates. A blockchain network is basically a distributed system. It implies that the software components used in its operation, as well as the data that flows between them, are dependent on various sources. These sources are network members, often known as nodes.

The role of blockchain network nodes is to convey complicated messages in order to share resources and achieve a common goal. In the case of a blockchain network, for example, those goals can be modifications to state, such as making changes to your wallet’s balance via transactions, block propagation, like verifying the hash of new blocks, or other sophisticated and non-trivial processes. 

What Role Do Blockchain Nodes Play?

As technology advances, blockchain technology’s popularity will only grow. Over the past few years, it has been widely used in a range of industries, including supply chain, healthcare, and energy. Therefore, in order to comprehend the dynamics and benefits that set blockchain technology apart from its conventional competitors, it is crucial to comprehend the fundamental architecture and infrastructure of the system.

The foundation of a blockchain system is its nodes. Their primary goals are to establish their legitimacy inside the network and improve the safety of the data on the blockchain. A blockchain network can include thousands of nodes to guarantee its traceability, immutability, and decentralization.

Because they keep track of every blockchain transaction, nodes contribute to dependability. Furthermore, as a blockchain network lacks one single point of failure, nodes may also defend the blockchain from centralized attacks. Every node utilizes a duplicate of the blockchain database to confirm transactions before adding them as blocks to the blockchain. Therefore, a blockchain is more trustworthy the larger its node network.

On the blockchain, nodes may be used for a wide range of tasks, such as managing, keeping track, and ordering blockchain transactions, rejecting and storing data, and upholding the consensus mechanism. Nodes must also decide if a block of transactions or signatures is valid before accepting or rejecting it in order to maintain the network.

Read Blog Post: The Core Concept of Blockchain Development

How Do Nodes Function in a Blockchain?

After talking about what a blockchain node is, it is crucial that we understand how nodes function. In order to do that, it is first required to revisit blockchains to understand how they operate. A blockchain is a shared, immutable record in which every block is cryptographically connected to every other block. This means that if one portion of the blockchain changes, it will affect every block that comes after it. They are impervious to alteration, though, because they are numerous copies and reside on a dispersed network.

Physical network nodes are distinctive in that they may all be identified from one another by a certain trait or attribute. Their duties may vary based on the nature of the application. As was previously said, the term “node maintenance” refers to the maintenance of blockchain transaction data, although not all nodes perform this job. The general specifications of the blockchain determine what the node accomplishes. In addition to the typical responsibilities of handling transactions, exchanging data with other nodes to expand the network, and putting an algorithm into place to maintain network updates and functionality, every node in the blockchain ecosystem has a distinct duty to perform.

RPC nodes are specialized kinds of blockchain nodes that are set up to do more complicated operations on the network, such as retrieving transactions from smart contracts or acting as reliable middlemen in certain transactions. These nodes are often operated and typically possess substantial processing power and resources.

Types of Blockchain Nodes

Types of Blockchain Nodes

Understanding the various types of network nodes and how they work for different blockchain levels is essential to comprehend what a blockchain node is.

1. Full Nodes

In order to completely validate transactions and blocks against the network’s consensus rules, a full node keeps the complete blockchain. Furthermore, complete nodes are essential for dispersing this information around the network interfaces and guaranteeing the prompt and effective distribution of new blocks and transactions. However, full nodes often refrain from recommending fresh blocks to be added to the blockchain.

Furthermore, full nodes are important for blockchain network governance. The decision of complete nodes to accept or reject proposed protocol upgrades or changes becomes a potent consensus signal. 

2. Archive or Archival Nodes

In contrast, an archive node is a more advanced version of a complete node that retains data for a longer period of time. An archive node not only saves the whole blockchain but also painstakingly preserves all previous network states, including all transitional states between blocks. This implies that an archive node records and maintains the change that results from every operation, including transactions, contract execution, and other activities. It’s similar to having a time capsule of the whole blockchain’s past, enabling engineers to go back in time and examine any particularly interesting point.

An archive node is a vital tool for projects that need to delve deeply into previous data or for troubleshooting intricate smart contracts. This depth of knowledge does, however, come at a price, since an archive node requires significantly more storage than a typical full node, making it necessary to maintain a significant infrastructure and financial commitment. Once more, anyone can operate an archive node on chains without authorization.

3. Validator Nodes

Validator nodes, also known as staking nodes in certain networks, participate more actively in the block-building process than standard full nodes, which are mainly responsible for transaction validation and relaying. They are selected to verify and add new blocks to the chain based on a variety of criteria, including the quantity of native cryptocurrency staked, reputation, and other considerations. These nodes contribute to reaching an agreement on the blockchain’s future state by suggesting or approving new blocks.

A variety of roles are played by validator nodes in blockchain network services such as Shardeum. When it’s their turn, they each independently verify, come to an agreement on, and handle transactions without taking the lead. The network groups these transactions into batches or blocks once they have been verified. The network’s archive nodes receive these aggregated transaction groups and propagate them for thorough storage and historical record-keeping.

All things considered, the aforementioned are predicated on the notion that validators behave honorably. If they participate in malevolent activities or validate transactions or blocks erroneously, they will be subject to severe penalties, also referred to as “slashing,” which may result in the loss of their staked assets. Therefore, in some blockchain ecosystems, validator nodes serve as a combination of authority and trust, maintaining network integrity and promoting decentralization.

4. RPC Nodes

In a blockchain network, Remote Procedure Call nodes, or RPC nodes, are essential access points. They execute requests and carry out certain tasks to enable external interactions with the blockchain. RPC nodes are used for communication by developers, apps, and other network users to send transactions, retrieve data, and check the network’s status. These nodes decipher these external requests, send them to the blockchain, and then provide the proper answers. 

RPC nodes are essential for spanning the gap between external entities and the underlying blockchain technology applications, even if they are not directly engaged in consensus or block validation. This helps to make the network more accessible and useful for a variety of applications and services. Their existence emphasizes how crucial usability and accessibility are to increasing the adoption of blockchain technology.

5. Mining Nodes

On Proof-of-Work (PoW) blockchains, like Ethereum and Bitcoin (as of this writing), miners, also known as mining nodes, are in charge of finishing the tasks necessary to generate a block. Usually, this effort requires figuring out intricate mathematical problems in order to get the right answer, which is a hash output that verifies the block.

The work is accomplished using a variety of hardware components, such as the Central Processing Unit (CPU), Graphics Processing Unit (GPU), or Application-Specific Integrated Circuit (ASIC), depending on the protocol requirements. If consensus is reached beforehand, the first person to successfully finish the task at hand and announce it to the network asserts the right to propagate the block.

6. Pruned Full Nodes

While pruned nodes have a more storage-efficient approach, their basic functioning is quite similar to that of complete nodes. They discard older data to stay below a certain storage barrier, giving priority to current blocks instead of keeping the complete blockchain. A pruned node will first download the blockchain; but, while it runs, it will gradually remove earlier blocks so that only the most current information that complies with its predetermined storage specifications is kept. 

For instance, if an operator sets aside 550MB for a pruned node, it will keep the most recent blocks that meet this restriction and remove older data as needed. Even with their more efficient storage approach, pruned nodes still have the complete node functionality to verify transactions and participate in consensus processes.

7. Authority Nodes

A node designated as an authority by the community or entity in charge of managing a blockchain is called an authority node. They serve as permission for new nodes to join a blockchain. Additionally, if another node needs to access a certain data channel, they can control the access permissions of other nodes. Authority nodes are used by consensus methods like Delegated Proof of Stake and Proof of Authority, which are not entirely decentralized. 

A certain number of authority nodes are necessary for the operation of such consensus methods. The development team normally determines or the community votes on the number of authority nodes and who they will be. The lightweight nodes that other network users will be operating depend on the data transmitted by the authority nodes in order to function on the blockchain.

8. Masternodes

Full nodes called masternodes are in charge of verifying transactions and keeping up the blockchain ledger. They are unable to add new blocks to the blockchain, though. Masternodes are typically more potent than ordinary nodes. Nodes in blockchain may help other blockchain-based events as well, depending on the type of event. These include overseeing voting events, executing protocols, and upholding the relevant blockchain regulations.

Masternodes are nonetheless crucial to the network’s functionality and security even if they don’t contribute as many new blocks as full nodes do. In addition to helping to keep the network secure, users that operate masternodes might potentially get a portion of the benefits for their labor. 

9. Light Nodes

To enable portable interaction with Web3, light nodes only need to carry the headers of blocks, not the whole weight of the blockchain. Because it is typically located on the user side, like a wallet interface, this kind of node is the most prevalent one in the space.

Technically speaking, light nodes—also known as Simple Payment Verification (SPV) nodes—depend on full nodes to supply them with the data they require to carry out their functions. They can only disseminate transactions to the network for processing and check the most recent block’s status because they do not personally possess a copy of the blockchain.  

What are Blockchain Node Providers?

Blockchain node providers play a pivotal role in the infrastructure of blockchain networks, offering essential services to support the operation and maintenance of blockchain nodes. In the decentralized world of blockchain technology, nodes are crucial components that validate and relay transactions, maintain copies of the blockchain ledger, and ensure the overall integrity and security of the network.

Blockchain node providers are third-party entities or service providers that offer infrastructure services specifically tailored to support blockchain networks. They facilitate the deployment, management, and operation of blockchain network nodes, allowing individuals, businesses, and developers to interact with blockchain networks without the need for extensive technical expertise or infrastructure investment.

Blockchain and Healthcare: Potential and Opportunities

Posted on by Shipra

“Blockchain” is one of the most popular buzzwords in the world of medical technology. Among a slew of cutting-edge technologies, blockchain stands out for its enormous potential in the telemedicine business, particularly for efficient health care in general.

In some respects, blockchain has made electronic health records more patient-centric. The decentralized data storage model allows patients to receive simple and rapid access to medical data from many providers, making the patient’s journey more rewarding.

Blockchain can transform healthcare. With its full implementation, patients may be prioritized at the heart of all operations, completely revamped with improved security, privacy, and accessibility.

Blockchain makes it almost hard to imitate, distort, or otherwise fabricate data since it is accurate, secure, and a catalyst for full responsibility. This offers a plethora of possibilities, the most important of which is the interchange, storage, and access of data between linked parties.

Another compelling feature of blockchain is its use in medical staff certification verification.

Blockchain - A game changer in healthcare

Because blockchain is open and safe, it may be used in the medical business in several ways, dramatically decreasing prices and new methods for people to obtain treatment.

When combined with the compounding nature of data and invention, futureproofing technology may be used to generate an age of growth and innovation.

Pioneering firms are already laying the groundwork for a blockchain revolution.

Better transparency and privacy

Blockchain networks enable enterprises to create both openness and privacy, which aids in concealing critical patient data. Patients have access to their records and the data ledger, allowing them to know who is seeing their information. This alleviates the stress of wondering whether third parties are obtaining access to sensitive information and may aid in the restoration of confidence that has been eroded as a result of previous data breaches.

Attackers would need huge computing powers to target a blockchain-powered network, drastically restricting the frequency, likelihood, and efficacy of such assaults.

With a data-driven, patient-centric network, blockchain has transformed the medical scene. It provides best-in-class security for all linked data and parties while allowing close and simple contact with responsible parties.

Reports in real-time

Remote gadgets powered by blockchain are connected to a bigger patient center that houses all patient data. This lets healthcare practitioners more easily access all of a patient’s facts, delivering more accurate individualized treatment for each patient.

These gadgets monitor blood pressure and pulse and give information that may be used to diagnose sleep apnea, narcolepsy, and even epileptic seizures. This information is essential for physicians since it allows them to monitor their patients in real-time to ensure that everything is under control.

Improved security

The most obvious advantage of blockchain-powered gadgets is the increased security they give. Blockchain is a more user-friendly security alternative for providers, and the apps they supply store data in more fragmented systems that are more difficult for hackers to access. Many hospitals nowadays have antiquated security systems and no specific personnel to guarantee that the system is functioning correctly.

Improves the management of patient cases

Blockchains can enhance the management of patient cases. Once a patient sees a physician and a treatment plan is produced, the treatment plan may be added to the blockchain ledger as part of the patient’s medical record. Then, a smart contract may be formed using all of the patient’s case management information. The contract establishes the framework for the patient’s treatment objectives and the smart contract’s criteria for monitoring and assessing the patient’s progress.

When a patient’s information is put to the blockchain, it may provide historical data on how the treatment was supplied and received. The health information is collected via wearable monitoring devices and social media platforms and then uploaded to the patient’s blockchain ledger, providing another degree of value. Smart contracts may once again be used to monitor a patient’s progress toward their health objectives.

Decreased complexity and expense

Older monitoring equipment might be somewhat complex. Some are implanted, networked gadgets that may be readily hacked and outdated. Hospitals lose hundreds of dollars to each patient when their gadgets are hacked, in addition to the physical expense of the outdated equipment.

The enhanced security of blockchain-powered gadgets keeps their costs substantially lower than traditional devices, and they are far less sophisticated. The fact that they are user-friendly implies that there will be less human error, which will benefit both patients and clinicians.

Drug development and the integrity of the supply chain

Blockchain in healthcare can increase supply chain traceability and transparency by providing the big picture and minute details of every pharmaceutical transaction. Blockchain technology is already being used by companies like IBM, Walmart, and UPS to enhance supply chain integrity.

If supply data is stored on a blockchain, patients may receive real-time information on any medicine from its manufacturing until delivery at a retail pharmacy. Whether it’s a patient’s health record or a pharmaceutical moving through the supply chain, blockchains have the potential to transform the system from disparate data pieces controlled by a single organization to the life history of any resource.

Blockchain technology is being used in vaccine manufacturing and tracking

In vaccination monitoring and delivery, blockchain technology has numerous key potential applications. In a world where counterfeiters are known to create and sell fake vaccinations, blockchain allows the legitimacy of vaccine shipments to be confirmed and their distribution to be tracked to guarantee they arrive at their intended places.

Breakthroughs from this pandemic’s unusual reaction are anticipated to allow new use cases for blockchain technology to produce, deliver, and manage vaccines in 2022.

Blockchain's Potential in EHR Data Management

It is critical to decentralize health information in electronic health records (EHR). Various players in the global digitization of healthcare systems are eagerly investigating the potential of blockchain in the telemedicine business.

Massive attempts to enhance the security and privacy of telehealth and telemedicine services by exploiting blockchain’s intrinsic qualities, particularly transparency, immutability, auditability, and user and data anonymity. The advantages of blockchain technologies are that they may be integrated with eHealth systems to form open networks.

One example is the possibility of blockchain-based eHealth for traceability, which aids in detecting fraud connected to patients’ insurance claims and verifying medical qualifications. Another tangible example is that a blockchain platform might aid in the determination of role-based permission for data upload in EHR. As a result, telehealth’s integrity, confidentiality, and dependability of health documentation have improved.

Decentralized blockchain-powered telemedicine will establish the groundwork for quick and real-time EHR. Cutting-edge technology and cryptographic techniques are paving the way for new horizons in cancer patient care.

A new data-sharing strategy in oncology is based on blockchain

Tele-oncology is one field where blockchain might usher in a new paradigm. Telehealth, which is part of the cancer care delivery continuum, had made some stunning achievements in recent years, riding the wave of the COVID-19 epidemic, when cancer treatment was mostly practiced remotely.

The blockchain architecture has underlain a new data-sharing paradigm in oncology, from obtaining data for clinical trials for cancer research to increasing access to on-demand teleconferences for cancer patients as varied and difficult as the issue of cancer management is, businesses in the telemedicine sector are eager to make use of decentralized public blockchain.

Cancer research organizations are collaborating with governments from many nations to use the characteristics of blockchain for comprehensive data management for research and treatment. Combining blockchain and artificial intelligence (AI) technologies have set the tone for new eHealth security measures.

Blockchain will be used to detect high-risk patients

Blockchain technology platforms have the potential to revolutionize cancer research and treatment. The possibility has already made ripples in cervical and breast cancer screening.

Companies enthusiastically support cutting-edge health informatics management systems banking on blockchain to handle patient-provider communication platforms. Following the identification of high-risk patients, blockchain-powered telemedicine will offer up new options in digital cancer genetic counseling. One example is the rising popularity of chat-bot counseling.

Remote monitoring and mobile health apps

Mobile health apps are becoming more important as technology advances. EMRs were revealed to be securely kept on a blockchain network, enabling the data to be instantly communicated with medical staff and utilized for self-monitoring and home care. Malware is especially susceptible in this regard, particularly root issues that enable a hacker to get the patient’s private key.

Conclusion

While many fascinating and innovative blockchain solutions have arisen from forward-thinking organizations throughout the globe, this is simply the beginning. Providers who switch to security solutions that incorporate blockchain technologies and cryptocurrency incentives automatically set themselves up for a more secure future.

They are not only rebuilding ties with their patients by rewarding them for simple actions, but they are also providing a new layer of security to their patients’ sensitive information. With data breaches increasing, data protection should be a top concern, particularly in the medical industry, and data security is a top consideration when employing blockchain applications.

Create NFT Digital Art in 3 Simple Steps

Posted on by Shipra

It would be quite surprising to know that a GIF file was recently sold at a price of 600,000 dollars at an auction. If it comes as a shock for you, then it is time to reconsider the definition of fine art and start exploring the world of crypto and non-fungible tokens or NFTs.

Understanding NFTs

NFTs or non-fungible tokens can simply be thought of as a digital certificate of authenticity. When some pieces of classic works of art, antiques, and other historical items are sold at auctions in the real world, they come with a certificate of authenticity certifying that they are genuine. Non-fungible tokens or NFTs happen to serve the purpose of the certificate of authenticity but for digital items in the virtual world of the internet.

NFTs allow GIFs, JPEGs, MP3s, videos, and almost any other file format to be certified as one-of-a-kind. This technology helps in enabling a new type of ownership for digital files in the virtual world of the internet that was not possible previously. NFTs can be bought, collected, sold, and even destroyed like any other physical item. As the NFTs are on the blockchain network, they come with a completely transparent transaction as well as a pricing history that is visible to anyone with an internet connection.

Now you might be thinking about how to create NFT digital art. The process of transforming your art into an NFT is known as minting. It refers to the process of creation of a new token on the Blockchain that will remain attached to that content forever. At the time when an artist mints a new NFT, they attach a built-in commission that usually ranges from 10 to 30 percent which they will receive when that work is resold in the future.

Requirements for Starting to Create an NFT

To create an NFT, you do not require in-depth knowledge of crypto. But you need to have an idea about a few tools needed to get started such as a crypto wallet and Ethereum. So, here are a few steps to follow to get going.

  1. Setting up an Ethereum Wallet

    – The first step towards the NFT journey is the creation of a digital wallet where the cryptocurrency used for buying, selling, and creating NFTs is securely stored. The wallet also allows the users to securely and safely sign in to create accounts on NFT marketplaces. There are a number of platforms that offer free wallets to store cryptocurrency. Most importantly, they work with most of the major NFT marketplaces as well as blockchain apps. A few good ones are Coinbase Wallet, MetaMask, Rainbow, etc.

  2. Buying a Small Amount of Ethereum

    – Most of the major digital art marketplaces charge some fees for turning your content into an NFT. So, it is required to buy some Ethereum for the purpose of covering the costs for the creation of the NFT. The price of Ethereum fluctuates every second and hence it is very difficult to track the same. The easiest way to get started in this regard is by choosing a dollar amount that any user is willing to invest and purchasing that much Ethereum.

  3. Connecting the Wallet to an NFT Marketplace

    – Once the wallet is set up and Ethereum is purchased, it is time to choose a marketplace where the user wants to create an NFT and list their work. Rarible happens to be an excellent marketplace for creators who are just getting started with NFT.

Creating an NFT Digital Art

Once the above requirements are met, you can start with the process of creating an NFT digital art.

Step 1 - Making a Digital Art File for the NFT

There is actually no single technique for creating a piece of NFT digital art. If the file created by a user is supported by the marketplace where the content is supposed to be listed, then it is going to work as an NFT. This, in turn, provides an opportunity for the content created to be monetized. Any image, text, JPG, MP3, PNG, or GIF can be an NFT. The users can make use of different tools to create digital art in order to make it look more interesting and attractive.

Step 2 - Pricing the Art and Listing on a Marketplace

After the digital art file for the NFT is created, it is required to be added to the chosen NFT marketplace for the purpose of minting the image as an NFT which is as simple as uploading a video to YouTube. Once you start the process, the platform will ask whether to mint the work as a one-of-a-kind piece or as a collection of multiple items. Then the required fees that come with the creation of the new NFT need to be paid and the piece of digital art goes live on the marketplace within a matter of just a few seconds.

Step 3 - Waiting for Bids

After the NFT digital art is listed, anyone on the platform can view it and place a bid for the NFT. The discoverability of the NFT greatly varies across the major NFT marketplaces. Thus, it would be a very good idea to promote one’s listings. Once the bids are made, the users can sell their NFTs as per the most suitable bid.

Conclusion

Once you have decided to create an NFT digital art, it is to be kept in mind that it is quite expensive. Turning a content piece into an NFT needs a new one-of-a-kind digital coin to be minted on the blockchain. Creating this coin needs a complex computational task that involves an entire network of computers. The use of the Ethereum network for the purpose of minting the NFTs comes with a “gas fee” for the energy as well as the effort which goes into that computation. This fee fluctuates every day and in some cases, it might be well over the sale price of the work itself. Thus, it is important to be prepared with the overall costs involved before getting into the business.
