What is Nethermind?
Nethermind is an Ethereum engineering and research company whose project was bootstrapped in 2017 and got an Ethereum Foundation grant in 2018 to build a full client. Its execution client powers about 30% of the Ethereum network, per its site. It also offers protocol engineering, L2 work, node operations and 400+ security audits.
How Nethermind works
Nethermind's best-known product is its Ethereum execution client, which you pair with a consensus client to run a full node or a validator.
It runs on 64-bit Linux, Windows 10+ and macOS 13+. The docs suggest 16 GB of RAM and 4 CPU cores for a mainnet node, 128 GB and 8 cores for an archive node, at least 2 TB of SSD storage, and a disk rated for 10,000 IOPS or more. An archive node needed at least 14 TB as of July 2023.
The paid side is services. Nethermind Security audits Solidity and EVM code, Rust on Solana, Cairo on Starknet, ZK circuits written in Noir, and AI applications, and it offers formal verification. It states over 1 million lines of code audited and 1,700+ vulnerabilities found. Other teams handle protocol and L2 engineering, node operations, compliance tooling and Bedrock, its software for institutions working on public networks.
How to start with Nethermind
- To run the client, install it with the Launchpad PPA on Ubuntu, winget on Windows or Homebrew on macOS, use Docker, or download a ZIP from GitHub Releases.
- Each package has a detached OpenPGP signature you can check with gpg, and the docs include a template for running the node as a systemd service under its own user.
- For an audit, use the Book a security review form on nethermind.io.
- Before booking, AuditAgent, Nethermind's AI code scanner, can check a repository first and offers $50 in starting credits.
- Early-stage teams can apply for audit funding programs in which Nethermind is an approved auditor.
Nethermind fees and limits
- Subsidies can lower an audit bill: the Ethereum Security Subsidy Program, funded with $1M by the Ethereum Foundation through Areta Market, covers up to 30% of audit cost, and the Arbitrum Audit Program, $10M in ARB over 12 months, can cover up to 100% for eligible teams.
The client is free and open source, with GPL and LGPL license files in its GitHub repository. Your costs are hardware, bandwidth and, if you validate, the consensus-client setup. Audit and engineering work is quoted per project.
Risks to know before using Nethermind
- Running a node yourself means your disk will fill over time: the docs say the database grows until you resync or prune, and slow disks can stop a node from syncing at all.
- If you validate, the docs tie disk speed directly to validator performance rewards and recommend SSDs over spinning disks.
- An audit reduces but does not remove contract risk.
