Consensus Mechanism ~ (Terms)

A consensus mechanism is the method used in a blockchain network to reach agreement on the state of the ledger, essentially ensuring everyone is on the same page. Imagine a group of people trying to decide the truth without a central authority: the consensus mechanism is the process they use to come to a unanimous conclusion.

Here’s a breakdown of the key aspects:

Validates new transactions added to the blockchain.Prevents double-spending (using the same digital asset twice). Maintains the integrity and security of the entire network.

Different mechanisms exist, but the basic idea is that nodes (computers on the network) propose and vote on new blocks added to the ledger. There are various ways this happens, depending on the specific mechanism:

Proof of Work (PoW): Nodes solve complex mathematical puzzles to earn the right to propose a block. The more computing power a node has, the higher chance it has of winning. (Think of it like solving a riddle before anyone else.)
Proof of Stake (PoS): Nodes “stake” their own cryptocurrency to participate in the validation process. The more tokens a node has staked, the greater its weight in the voting process. (Think of it like having more votes based on your investment.)

Without a consensus mechanism, anyone could add anything to the blockchain, leading to chaos and undermining trust in the system. It ensures everyone agrees on the validity of transactions and protects the network from manipulation.

Different consensus mechanisms have their own pros and cons, such as energy efficiency and scalability. Worldcoin currently uses a variation of Proof of Stake (PoS) for its consensus mechanism.
