Bor is the official Golang implementation of the Polygon Proof-of-Stake blockchain, providing an EVM-compatible client forked from geth.
Bor is the official Golang client implementation for the Polygon Proof-of-Stake (PoS) blockchain. It is a fork of the Ethereum geth client, maintaining compatibility with the Ethereum Virtual Machine (EVM) up to the London fork. This makes Bor a critical component for running Polygon nodes that participate in block validation and network consensus. The client supports multiple node types including validator, sentry, and archive nodes, enabling flexible deployment architectures for different operational needs.
Bor is designed for infrastructure developers and node operators who want to run Polygon PoS nodes with a reliable, open-source client. It supports both the Polygon mainnet and the Amoy testnet, with installation options via pre-built packages or building from source. The client includes a new command-line interface introduced in version 0.3.0, which retains compatibility with previous flag usage while improving usability. Comprehensive documentation and community support are available through Polygon's official wiki, forums, and Discord channels.
What sets Bor apart is its direct lineage from the Ethereum geth client combined with Polygon-specific optimizations and configurations. This ensures seamless EVM compatibility while enabling Polygon's unique PoS consensus and scaling features. The client is actively maintained with regular releases and a strong emphasis on code quality, testing, and community contributions. Developers can get started quickly using the provided installation scripts or by compiling from source, with detailed guides covering configuration and node operation.
Running a reliable, EVM-compatible client for Polygon's PoS blockchain requires specialized software that supports Polygon's consensus and network architecture. Existing Ethereum clients do not natively support Polygon's PoS chain, creating a need for a dedicated client implementation.
Automates setup by installing binaries, creating users, configuring services, and deploying appropriate config files.
Improved CLI introduced post v0.3.0 with backward-compatible flag usage for easier node management.
Encourages community contributions with clear coding standards, testing requirements, and pull request processes.
Infrastructure teams deploy Bor validator nodes to participate in block production and consensus on the Polygon network.
Operators run sentry nodes using Bor to protect validator nodes by filtering incoming traffic and mitigating attacks.
Developers and analytics providers use Bor archive nodes to access full blockchain history for querying and data analysis.
