The Efficient
Ethereum Execution Client
Seven years of Ethereum client development, culminating in Erigon 3: a ground-up redesign that delivers dramatically lower disk usage, faster sync, and the infrastructure needed for the ZK-proof era.
Erigon 3: A Novel Architecture
After 7 years of R&D, Erigon 3 represents a complete rethinking of the Ethereum execution client. Built from the ground up with modularity at its core, Erigon 3 separates the execution layer into composable components that can be deployed independently or together.
The result is an execution client that is dramatically more efficient in disk usage, syncs faster on commodity hardware, and provides the foundation for the ZK-proof-verified future of Ethereum.
Erigon Archive
Native distributed ledger technology designed for optimal blockchain data storage and retrieval. The database layer underpinning Erigon's efficiency advantage.
Caplin
Embedded consensus layer client that ships with Erigon 3, enabling a single-binary deployment of a full Ethereum node without external dependencies.
Torrent Sync (OtterSync)
BitTorrent-based synchronization for historical state via immutable .seg snapshot files. Download ~99% of chain state without re-executing every block.
Historical Proofs
Production-stable eth_getProof for any historical block. Underpins stateless clients and ZK-proof integration at the execution layer. Requires 32 GB+ RAM; enable with --prune.include-commitment-history.
Why Erigon
Caplin — Integrated Consensus
Built-in consensus client — no separate Lighthouse or Prysm to run. One binary handles both execution and consensus, simplifying setup for stakers and node runners.
Efficiency
4× smaller Chaindata (~20 GB) in Erigon 3.4. Run a full archive node on hardware other clients can't.
OtterSync
Shifts initial sync from CPU-intensive transaction re-execution to network download — BitTorrent for state data. Reduces sync time for both full and archive nodes.
Modularity
Core node, RPC daemon, and tx pool run as independent processes. If one crashes the rest stay alive. Run multiple instances without downtime.
Predictable RPC Performance
No background compaction means no unpredictable resource spikes. RPC throughput stays stable and consistent — critical for providers and validators.
MCP — AI-Native Node
Built-in Model Context Protocol server lets AI agents query blocks, transactions, traces, logs, and state directly from your node. Ask questions in plain language, build agentic workflows, and integrate Ethereum data into any MCP-compatible tool.
Fast Restart
Non-blocking startup: Erigon is live at ChainTip immediately. Indexing and pruning run in the background, and Caplin resumes historical downloads across restarts without losing progress.
Immutable, Decentralised Data
Historical data lives in immutable .seg files distributed via BitTorrent — up to 10× cheaper to backup, repair, and distribute. No double-disk usage, no complex serialisation.
MEV Protection
Integration with Shutter Network for MEV protection on Gnosis Chain, protecting users from front-running and sandwich attacks. Coming soon to Ethereum mainnet.
