Cross-Shard Transactions

Definition

Cross-shard transactions involve operations that span multiple partitions, or shards, of a blockchain network. In sharded blockchain architectures, the network state and transaction processing are divided among several smaller, independent segments to enhance scalability. A cross-shard transaction requires coordination and communication between these distinct shards to ensure atomicity and consistency across the entire ledger. This mechanism is crucial for maintaining the integrity of data when operations involve assets or states residing on different segments.
