Chainlink

Not currently supported on BlockCard; data on currently unsupported cryptocurrencies is included for your convenience.

Chainlink enables smart contracts to realize their full potential and become the dominant form of digital agreements. Chainlink couples sound cryptography software with Town Crier hardware systems to create provable, secure decentralized oracle networks. Chainlink’s decentralized oracle networks provide a secure and tamper-resistant environment for smart contracts to interface with events, data feeds, and payment methods to create binding valuable digital agreements.

Chainlink’s decentralized and secure infrastructure enables sustainable price feeds for DeFi. Your smart contracts won’t trigger until after the system validates the market data from premium APIs. And this offers users extensive reliability guarantees for the quality of the smart contracts. Chainlink’s easily verifiable on-chain data ensures end-to-end security for users–making smart contracts a viable reality.

High-quality data providers capture and aggregate raw price data from centralized and decentralized exchanges. Then independent nodes within Chainlink’s network retrieve market prices from data providers and generate tamper-resistant price updates. This allows smart contracts, using a simple function call, to access accurate on-chain price updates.

By utilizing Chainlink, your smart contracts can access data feeds, APIs, and payments in a proven secure environment. And Chainlink works across all blockchain-based applications, Ethereum, Bitcoin, Hyperledger, etc. Chainlink can quickly and easily be set up for individuals and enterprises.
