## What it is
Bor is the official Golang implementation of the Polygon PoS blockchain, forked from go-ethereum and EVM compatible. It runs full nodes, validators, sentry, and archive nodes on Polygon mainnet and Amoy testnet.

## Use cases
- run a Polygon PoS full node
- operate a Polygon validator node
- set up a sentry node for a validator
- run an archive node for Polygon
- query EVM-compatible JSON-RPC and trace APIs on Polygon
- sync Polygon mainnet or Amoy testnet locally

## When to choose
- you need to run or validate on Polygon PoS mainnet or Amoy
- you want a Geth-like client with Parity-compatible trace APIs for Polygon
- you need self-hosted Polygon node infrastructure

## When to avoid
- you need a client for other EVM chains like Ethereum mainnet itself
- you want a lightweight wallet or dApp frontend rather than a node
- you need ZK-based Polygon chains (CDK), which use different software

## Facets
- artifact type: application
- maturity: active
- function: blockchain, cli, http-server, rpc
- domain: blockchain, developer-tools
- platform: windows, go, cli
- tags: polygon, pos, evm, geth-fork, validator, sentry-node, archive-node, cryptocurrency, linux, macos
