Consensus Optimization

Definition ∞ Consensus optimization refers to efforts aimed at improving the efficiency, speed, and scalability of a blockchain’s consensus mechanism. This involves refining the algorithms and processes by which network participants agree on the validity of transactions and the order of blocks. The objective is to achieve higher transaction throughput and lower latency without compromising security or decentralization. Various protocol upgrades and new consensus models represent attempts at this improvement.
Context ∞ Much of the ongoing blockchain development and news focuses on achieving consensus optimization to address limitations in current network performance. Discussions often compare different consensus protocols, such as Proof of Stake versus Proof of Work, and their respective advantages in this regard. The pursuit of more efficient consensus is a critical driver for broader adoption of decentralized applications.
