Sharding
Protocol
Partitioning state or processing to scale throughput.
Sharding divides a blockchain into shards that process in parallel. It boosts capacity but needs strong data availability and messaging between shards.
Frequently asked questions
How does sharding help scale?
It splits work across shards so more transactions can be processed in parallel.What challenges exist?
Data availability, cross shard messaging, and security coordination.Is sharding live on Ethereum today?
Ethereum is pursuing data availability scaling first. Follow official updates for roadmap details.
