# Chainlink

> LINK Everything

Chainlink provides decentralized oracle infrastructure for blockchain networks, delivering offchain data, computation, and cross-chain connectivity to smart contracts.

Chainlink provides decentralized oracle infrastructure enabling smart contracts to securely access offchain data, computation, and cross-chain interoperability. The platform operates through multiple oracle services including data feeds for price information, cross-chain messaging protocols, verifiable randomness generation, and automated transaction execution. Chainlink infrastructure secures protocols across DeFi, capital markets, and institutional applications.

## Products

- [Chainlink Data Feeds](https://thegrid.id/profiles/Chainlink): Chainlink Data Feeds deliver real-world data to smart contracts through decentralized oracle networks using offchain reporting. The system aggregates data from multiple sources and publishes verified information onchain through proxy and aggregator contract architecture. Data Feeds provide price feeds, SmartData feeds with multiple-variable responses, and Smart Value Recapture mechanisms for protocols. (Oracle, Live, Main Product)
- [Chainlink VRF (Verifiable Random Function)](https://thegrid.id/profiles/Chainlink): Chainlink VRF generates verifiable random numbers for smart contracts through cryptographic proof mechanisms published and verified onchain. The system prevents tampering by oracle operators, developers, or miners through cryptographic verification of random value generation. VRF v2.5 supports subscription-based and direct funding payment models with LINK or native tokens. (Developer Tooling, Live)
- [Chainlink Automation](https://thegrid.id/profiles/Chainlink): Chainlink Automation executes smart contract functions through decentralized oracle networks monitoring onchain conditions and time-based triggers. The system automates transaction execution without centralized infrastructure, uses the same node operators securing Chainlink data feeds, and enables developers to offload operational maintenance for protocol automation workflows. (Developer Tooling, Live)
- [Chainlink CCIP (Cross-Chain Interoperability Protocol)](https://thegrid.id/profiles/Chainlink): Chainlink CCIP is a blockchain interoperability protocol facilitating token transfers, arbitrary messaging, and programmable token transfers across chains. The system uses decentralized oracle networks for transaction validation, implements rate limiting for risk management, and features timelocked upgrades through role-based access control. CCIP enables atomic and hybrid settlement workflows across public and private blockchains.
 (Cross-chain Infrastructure, Live)
- [Chainlink Data Streams](https://thegrid.id/profiles/Chainlink): Chainlink Data Streams delivers low-latency market data offchain with onchain verification through a pull-based oracle design. The system provides sub-second data resolution with cryptographic proof generation, includes liquidity-weighted bid-ask prices and volatility metrics, and uses active-active multi-site deployment for high availability. Data Streams supports REST API, WebSocket, and SDK integration methods. (Oracle, Live)
- [Chainlink Functions](https://thegrid.id/profiles/Chainlink): Chainlink Functions provides smart contracts with trust-minimized compute infrastructure for API data retrieval and custom computation execution. The system operates through decentralized oracle networks that execute source code in serverless environments, aggregate independent results through consensus, and support threshold-encrypted secrets for authenticated API access. (Developer Tooling, Live)
- [Chainlink Runtime Environment (CRE)](https://thegrid.id/profiles/Chainlink): Chainlink Runtime Environment is an orchestration layer for institutional smart contracts enabling data connectivity, compliance, privacy, and cross-chain interoperability. The system compiles workflows into WebAssembly binaries executed across decentralized oracle networks, uses Byzantine Fault Tolerant consensus for operation verification, and supports Go and TypeScript SDK development. (Developer Tooling, Live)
- [DataLink](https://thegrid.id/profiles/Chainlink): DataLink is an institutional-grade data publishing service that enables data providers to commercialize specialized market data onchain through Chainlink's decentralized oracle infrastructure. Providers integrate via existing REST or WebSocket APIs, with Chainlink nodes reaching consensus before delivering signed reports through pull-based or push-based feeds. DataLink supports equities, FX rates, bonds, commodities, credit ratings, derivatives, and other institutional datasets across public and private blockchains. (Pricing Data API, Live)
- [Chainlink Runtime Environment](https://thegrid.id/profiles/Chainlink): Chainlink Runtime Environment (CRE) is a developer platform that lets builders compose modular oracle capabilities into custom cross-chain workflows using Go, TypeScript, and other languages. It re-architects Chainlink's platform into purpose-built decentralized oracle networks (DONs) per capability, coordinated through DON-to-DON communication. CRE enables institutional-grade smart contracts to operate across public and private blockchains with built-in compliance and privacy support. (Developer Tooling, Live)
- [Chainlink Privacy Standard](https://thegrid.id/profiles/Chainlink): Chainlink Privacy Standard is a developer framework that enables private smart contracts on public and private blockchains by combining trusted execution environments (TEEs), zero-knowledge proofs, and the DECO protocol. It provides confidential computing through Chainlink Confidential Compute, selective disclosure for regulatory compliance, and cross-chain private transaction support via CCIP. Institutions use the standard to protect trade logic, tokenized asset metadata, and KYC credentials while remaining auditable to designated counterparties. (Developer Tooling, Early access)

## Assets

- [Chainlink (LINK)](https://thegrid.id/profiles/Chainlink): LINK is the utility token of Chainlink. It is used to pay node operators for delivering offchain data, executing computation, and facilitating cross-chain messaging services. The network operates through a decentralized oracle infrastructure that enables smart contracts to securely access real-world information, with node operators staking LINK as collateral to ensure reliable data delivery and service execution.
