Erigon
An efficiency-focused Ethereum execution client — re-architects state storage and sync to drastically reduce disk usage and archive-node footprint.
Erigon (originally "Turbo-Geth") rewrites Ethereum execution internals around a flat-file state representation that drops archive-node disk usage by an order of magnitude versus Geth. It also offers significantly faster initial sync.
The trade-off is a different architectural footprint and a different RPC surface — many tools optimized for Geth need adaptation. Erigon is widely used by archive-node operators and infrastructure providers for whom disk is the binding constraint.
