The wod consensus mechanism means the method by which participants in a blockchain network agree on the current state of the ledger essentially, how everyone agrees which transactions are valid and in what order Because blockchains are decentralized (no single authority) consensus mechanisms are crucial for ensuring trust, security, and consistency across all nodes in the network.

Some Common Consensus Mechanisms are:

1. Proof of Work (PoW):

i). Used by Bitcoin.

ii). Miners compete to solve complex math problems then the winner adds the next block and earns rewards.

iii). Secure but energy intensive.

2. Proof of Stake (PoS):

i). Used by Ethereum.

ii). Validators are chosen based on how much crypto they stake as collateral.

iii). More energy efficient than PoW.

3. Delegated Proof of Stake (DPoS):

i). Token holders vote for a small number of trusted validators.

ii). Used in networks like EOS and Tron.

4. Practical Byzantine Fault Tolerance (PBFT):

i). Nodes come to agreement even if some are faulty or malicious.

ii). Used in permissioned blockchains.

In essence a consensus mechanism ensures that everyone plays by the same rule even in a trustless environment.

That's all for now 

I hope you learn something new 

Good luck 🫶 🤞
