Event-Driven Shard Synchronization refers to a mechanism designed to improve efficiency in blockchain networks that use sharding. Sharding breaks the database into smaller parts called shards to handle transactions concurrently, enhancing scalability.In this process, each shard processes its own transactions and smart contracts. Event-driven synchronization ensures that when events occur—such as a transaction affecting multiple shards—those relevant shards are notified instantaneously. This reduces latency and enhances coordination between shards.When a particular event triggers a change in state, only the affected shards are involved in the synchronization process. This minimizes overhead, allowing for more rapid confirmation of transactions across the network.Overall, this mechanism helps maintain a seamless flow of information and improves the overall responsiveness of the blockchain system while managing complex interactions between shards.
