## What it is
Prysm is a Go implementation of the Ethereum Consensus (proof of stake) specification, developed by Offchain Labs. It runs beacon chain nodes and validators, enabling users to participate in Ethereum staking on mainnet.

## Use cases
- run an ethereum consensus layer node
- stake eth as a validator on mainnet
- operate a beacon chain client in go
- sync the ethereum beacon chain
- validate blocks and attestations on ethereum proof of stake

## When to choose
- you want a production-tested Go consensus client for Ethereum
- you plan to stake ETH and need a validator client
- you prefer a client with extensive official documentation and community support

## When to avoid
- you need an execution layer client like Geth or Nethermind
- you want a lightweight non-blockchain tool
- you prefer consensus clients written in other languages such as Rust or Nim

## Facets
- artifact type: application
- maturity: active
- function: blockchain, networking, cli, monitoring
- domain: blockchain, microservices, infrastructure-as-code
- platform: windows, go, cli
- tags: ethereum, proof-of-stake, consensus-client, beacon-chain, validator, staking, golang, cryptocurrency, linux, macos, docker
