Definition ∞ Sharding Consensus Pattern describes a method for horizontally partitioning a blockchain network into smaller, independent segments called shards, each capable of processing transactions concurrently. This architectural approach aims to enhance network scalability by distributing the workload across multiple parallel chains. Each shard maintains its own state and processes its own transactions. A main chain often coordinates the shards and maintains overall security.
Context ∞ News often reports on blockchain projects implementing or refining sharding consensus patterns as a primary strategy for addressing network congestion and improving transaction speed. The effectiveness of these patterns is critical for enabling decentralized applications to handle a large user base. Challenges include ensuring secure communication and data consistency between shards.
