Reth V2
Base’s execution client is Reth, a high-performance Ethereum client. Its next major release, Reth V2, goes straight at the two things that bound a high-throughput chain: how much disk a node burns and how fast it can compute state roots.
Storage V2
Section titled “Storage V2”Storage V2 reworks the on-disk layout to bring node storage requirements down sharply:
| Node type | Disk reduction |
|---|---|
| Full | ~30% |
| Minimal | ~50% |
| Archive | ~23% |
That lifts a disk-growth ceiling that would otherwise cap how far Base can push block throughput.
State root computation
Section titled “State root computation”Reth V2 rebuilds the state-root pipeline around three changes:
- Warm sparse-trie caching across blocks — skips recomputing subtrees that didn’t change from one block to the next.
- Parallel trie — spreads state-root work across CPU cores at once.
- Proof V2 — a reworked proof-generation path that trims per-proof overhead.
Performance
Section titled “Performance”Across Reth’s published benchmarks, those changes add up to:
- +33% throughput
- ~25% lower average block-execution latency
base-reth-node picks up these gains directly, adding headroom on the way toward 1 gigagas/s.
