What is Blockchain Sharding?. Sharding splits a blockchain’s workload across multiple partitions so the network can process more transactions in parallel.
How it works
Each shard handles a subset of data; a coordinating layer keeps security and cross‑shard communication consistent.
Why it matters
Sharding targets throughput without sacrificing decentralization if designed correctly.
Common pitfalls
- Confusing sharding with sidechains
- Assuming cross‑shard messaging is trivial
- Underestimating validator requirements
Quick example
A network spreads accounts across shards and uses proofs to move assets between them safely.
