Sharding
Also known as: Blockchain Partitioning, Parallel Chain Processing, Layer 1 Scalability
A blockchain scalability technique that splits the network into smaller partitions (shards) to process transactions in parallel.
Sharding is a Layer 1 scaling strategy that divides a blockchain into multiple parallel chains or 'shards'. Each shard processes its own set of transactions and smart contracts, improving overall throughput by enabling parallelism. Sharding reduces network congestion and gas fees without compromising decentralization or security. Ethereum plans to implement sharding alongside rollups as part of its long-term scalability roadmap. Cross-shard communication is critical and handled through protocols that maintain consistency and security across the ecosystem. It’s a complex but promising approach to scaling blockchains.
