For Consensus purposes, Hyperledger uses Crash Fault Tolerance (CFT). It achieves consensus for single as well as multiple org systems. The advantage of CFT or Crash Fault Tolerance is that it guarantees to remain undamaged to system failures, like crashes, network partitioning, etc. N nodes in your consensus system help to withstand up to N/2 such crashes.
