Definition ∞ Consensus Efficiency Metrics are quantitative measures used to evaluate the performance and resource consumption of a decentralized network’s agreement mechanism. These metrics assess how effectively and quickly nodes reach a collective decision on the state of the ledger. They often include factors such as transaction throughput, latency, and energy usage.
Context ∞ These metrics are central to comparing and improving various blockchain protocols, particularly in the context of scalability and environmental impact. Debates surrounding different consensus mechanisms, like Proof of Work versus Proof of Stake, frequently reference their respective efficiency metrics. Optimizing these measures is a key goal for developing high-performance and sustainable digital asset systems.
