Blockchain Protocol

Architecture

A blockchain protocol, fundamentally, defines the rules governing data validation and consensus within a distributed ledger. Its architecture dictates the network’s scalability, security, and overall operational efficiency, impacting transaction throughput and finality times. The choice of consensus mechanism—Proof-of-Work, Proof-of-Stake, or variations—is a core architectural decision, influencing energy consumption and vulnerability to attacks. Layer-2 solutions and sidechains represent architectural extensions designed to alleviate congestion and enhance functionality, often utilized in complex derivatives markets.
