The On-Chain Consensus Layer is a crucial component of blockchain systems that ensures all participants agree on the state of the network. It facilitates the validation and confirmation of transactions and blocks, maintaining the integrity and security of the blockchain.Different consensus mechanisms, like Proof of Work or Proof of Stake, govern how nodes reach this agreement. Each method has its own way of processing transactions and achieving consensus, impacting scalability, energy consumption, and decentralization.When a new transaction is made, it gets broadcasted to the network. Nodes validate the transaction according to the rules set by the consensus layer. Once enough nodes agree, the transaction is added to a new block, which is then appended to the blockchain.This layer not only prevents double-spending but also ensures that all nodes have a consistent view of the ledger. The strength of an On-Chain Consensus Layer is vital for the overall trust and reliability of the blockchain, allowing users to transact securely and with confidence.
