What are consensus mechanisms and which ones exist?

Modified on Tue, 4 Mar at 10:07 AM

Proof of Work (PoW):

Miners solve complex mathematical puzzles to validate new blocks, secure but energy-intensive.


Proof of Stake (PoS):

Validators are chosen based on their token holdings, more energy-efficient than PoW.


Delegated Proof of Stake (DPoS):

Participants vote on validators to create blocks, faster but less decentralized.


Byzantine Fault Tolerance (BFT):

Consensus mechanism that works even with faulty or malicious nodes.
