A consensus mechanism is a method for recording data in a distributed database or ensuring that the database remains secure
The database in this case is referred to as a blockchain; therefore, the consensus mechanism maintains it
What Is Proof-of-Stake vs. Proof-of-Work? Using randomly selected validators, Proof of Stake (POS) verifies transactions and creates new blocks. In contrast, Proof of Work (POW) competitively verifies transactions and adds new blocks to the blockchain.
