Consensus Mechanism
  • Consensus means everyone on the network is having the same information and database.
  • PoW/PoS is a cryptocurrency consensus mechanism for processing transactions and creating new blocks in a blockchain.
  • A consensus mechanism is a method for validating entries into a distributed database and keeping the database secure.
  • In the case of cryptocurrency, the database is called a blockchain—so the consensus mechanism secures the blockchain.

Both PoW/PoS consensus mechanisms help blockchains synchronize data, validate information, and process transactions. Each method has proven successful at maintaining a blockchain, although each has pros and cons. However, the two algorithms have very different approaches.
