Consensus Layer Logic

Definition ∞ Consensus Layer Logic comprises the set of rules and algorithms that govern how participants in a decentralized network agree on the validity of transactions and the order of blocks. This logic ensures all nodes maintain an identical and consistent record of the blockchain’s state. It is fundamental for preventing double-spending and maintaining network integrity.
Context ∞ Consensus layer logic is a central topic in blockchain development, with ongoing debates about different mechanisms like Proof of Work and Proof of Stake. News often covers upgrades or changes to this logic, such as Ethereum’s transition to Proof of Stake, due to their significant impact on network security, decentralization, and scalability. These developments are crucial for the long-term viability of blockchain protocols.
