Definition ∞ A sharded consensus protocol is a method used in blockchain networks to achieve agreement among participants across partitioned segments of the network. This protocol enables each segment, or shard, to process transactions independently while maintaining overall network security and consistency. It is a scaling solution designed to increase transaction throughput. Such protocols are crucial for supporting a large number of users and applications.
Context ∞ Sharded consensus protocols are a primary area of research and development for enhancing blockchain scalability, particularly for networks like Ethereum 2.0. A key discussion involves the complexity of coordinating security and data integrity across multiple shards. Future advancements aim to deliver highly scalable and secure blockchain architectures capable of widespread adoption.
