The Consensus Layer is a crucial component that ensures all participants in a blockchain network agree on the state of the ledger. It enables nodes to achieve a unified view of transactions, maintaining data integrity and security.When transactions are submitted, they need to be validated and recorded in a way that prevents double-spending or fraud. The Consensus Layer employs various algorithms (like Proof of Work or Proof of Stake) to facilitate this agreement among nodes. Each method has its advantages and trade-offs regarding speed, energy consumption, and decentralization.This layer not only confirms transactions but also determines how new blocks are added to the chain. By achieving consensus, it safeguards the network against malicious attacks and helps maintain transparency. Overall, the Consensus Layer plays a pivotal role in establishing trust among users, ensuring that everyone has a consistent and accurate version of the data.
