Cross-Shard Latency

Definition ∞ Cross-shard latency indicates the time delay experienced when transactions or data communicate between distinct shards within a sharded blockchain architecture. This metric measures the time needed for information to propagate and reach completion across separate segments of the network. It represents an essential performance metric for the responsiveness of a sharded system handling inter-shard operations.
Context ∞ Reducing cross-shard latency presents a primary challenge in developing scalable blockchain solutions. High latency can impede the processing speed of decentralized applications that rely on interdependent cross-shard transactions, affecting user experience and system throughput. Protocol advancements and novel consensus approaches are under continuous development to lessen these delays, consequently augmenting overall network efficiency.
