Geth vs Erigon: which Ethereum execution client to run
The choice of execution client is not abstract. It determines how much disk space you need, how fast your node syncs, and what data you can retrieve. Geth is the reference. Erigon is the alternative that prioritises storage efficiency. Nethermind sits in between.
These differences matter in practice. Here is what to expect.
Disk footprint
Erigon's headline advantage is space. A full Erigon node typically occupies 2 - 3 TB as of mid-2025. Geth on the same chain state requires roughly 4 - 6 TB. Nethermind falls closer to Geth's range.
The reduction comes from how Erigon stores data. It keeps only the latest state and historical trie snapshots, discarding intermediate nodes that Geth retains. This makes archive nodes feasible on consumer hardware. A Geth archive node can exceed 12 TB. Erigon archive nodes often fit in 4 - 5 TB.
If you run multiple nodes or have limited disk, Erigon is the practical choice. If you want the simplest default setup, Geth works out of the box.
Sync speed
Initial sync is faster on Erigon for most hardware configurations. Erigon downloads era files in bulk and processes them in order. Geth uses a sequential block replay that can take days longer on comparable hardware.
Erigon's staged sync processes headers, bodies, then state separately. It parallelises well. Geth's snap sync is faster than its earlier modes but still lags Erigon on a clean sync.
Once synced, both clients stay close to the tip. Neither has a meaningful advantage in live block propagation.
RPC compatibility
Geth supports the widest set of RPC methods. It is the standard for eth_call, eth_getLogs, and eth_getTransactionReceipt. Most tooling and wallets expect Geth's behaviour.
Erigon implements the same core methods but diverges on some edge cases. The most common friction is the trace_ API.
Trace API differences
Geth supports debug_traceTransaction and trace_call. Erigon supports them too, but the output format differs: Erigon returns flat traces by default, while Geth returns structured call frames. If your tooling expects Geth's format, you may need to convert or adjust.
Erigon also offers trace_block and trace_transaction via the trace namespace. Geth does not implement these. If you rely on Parity-style traces, Erigon is the only option among the three.
Nethermind supports trace_block and trace_call but has limited debug_traceTransaction support. Nethermind's tracing is stable but less comprehensive than Erigon's.
Which client for which use case
Run Erigon if you need an archive node on limited storage, need Parity-style trace APIs, or want the fastest initial sync.
Run Geth if you want the broadest RPC compatibility, or if you run production infrastructure where tooling expects Geth's exact behaviour. Geth is the safest default for general use.
Run Nethermind if you run a .NET shop or need a client that balances size and compatibility. Nethermind has competitive sync speed but its disk footprint is not far behind Geth.
You can mix clients in your infrastructure. Running two different execution clients reduces the risk of a consensus bug taking out your entire setup. Erigon and Geth complement each other well: one for archive data, one for canonical RPC.
No client is universally better. Each trades off storage, speed, and API compatibility. Choose based on what your workload actually needs.
