👉 Consensus engineering is a methodology used in distributed systems, particularly in blockchain and decentralized networks, to achieve agreement among multiple nodes on the state of the system or the validity of transactions. It involves designing protocols and algorithms that enable nodes to converge on a single, consistent view of the network's state, despite potential discrepancies or conflicting information. This is typically achieved through mechanisms like proof-of-work, proof-of-stake, or Byzantine Fault Tolerance, which incentivize nodes to follow the majority rule or a predefined consensus protocol. By ensuring that all nodes agree on the same data, consensus engineering maintains the integrity, security, and reliability of the distributed system, preventing issues like double-spending or conflicting transaction records.
