Definition ∞ Sharding infrastructure refers to the architectural components and protocols that divide a blockchain network into smaller, interconnected segments called “shards.” Each shard processes a subset of transactions and data independently, enabling parallel processing. This design significantly increases the network’s overall transaction capacity.
Context ∞ Sharding infrastructure is a long-term scaling strategy for several major blockchains, including Ethereum, aiming to dramatically enhance throughput and reduce network congestion. The current focus involves implementing data sharding (data availability sampling) as a precursor to full execution sharding, which will allow for greater data availability for rollups.
