Cross-Shard Transaction Processing

Definition

Cross-Shard Transaction Processing describes the method by which transactions spanning multiple shards or partitions of a blockchain are executed and finalized. This mechanism addresses the complexities of maintaining data consistency and atomicity across fragmented ledger states. It permits increased transaction throughput by distributing computational load while preserving the integrity of operations that touch different parts of the network. The efficient coordination of these inter-shard operations is a key challenge for scalable blockchain architectures.
