## Description

Nethermind is the official Microsoft .NET implementation of the Ethereum protocol. It runs a full Ethereum execution node, synchronizes chain data, and provides a local endpoint for wallets, applications, and consensus clients. It is for homelabbers, Ethereum operators, and staking environments that need a self-hosted execution client. Use Nethermind when you want a widely used, actively maintained Ethereum client with Docker images.

## Common questions

### How do I connect a consensus client like Lighthouse to Nethermind?

Start Lighthouse with the execution endpoint set to localhost port 8551 and the execution JWT set to your jwt.hex file. The endpoint must be reachable by Nethermind, and both clients must use the same JWT file.

### What KZG setting can block startup or cause sync problems?

If your setup uses a local KZG file, set Init.KzgSetupPath to the file location. Without that path, Nethermind may not know where to find the file, which can block startup or cause sync problems if the file is required.

### Do OP Stack operators need a separate op-node with Nethermind?

No, Nethermind builds a rollup node directly into the client for OP Stack operators. It fully replaces the separate op-node and reduces the stack from two services to one.

### How can self-hosters monitor Nethermind?

Nethermind exposes node health and performance through a built-in UI and Prometheus metrics.

### Can Nethermind keep existing Geth wallets and applications working after migration?

Nethermind supports the same JSON-RPC API as Geth, so it can serve as a local endpoint for wallets and applications.
