Chainlink enhances smart contract functionality by providing secure and reliable access to real-world data and off-chain computation, while preserving blockchain’s security features. This repository includes Chainlink’s core node and contracts, facilitating participation in a decentralized oracle network. Node operators can access pre-built Docker images from Chainlink’s Dockerhub. Developers can find resources in the Chainlink Hardhat Box and are encouraged to contribute per the guidelines provided. Active community engagement occurs primarily on Discord. The core node requires Go 1.22, NodeJS v20, and PostgreSQL 12.x or above, with a necessary connection to an Ethereum node (such as Geth or Besu). Chainlink supports external adapters via REST API, enhancing extensibility with custom computations. The repository features a robust development environment, including tests, mock generation with mockery, and integration tests utilising Go modules. Chainlink promotes secure development using cosign for release verification and supports continuous iteration with changesets.
