Chainlink (LINK) is a blockchain abstraction layer that enables universally connected smart contracts. It uses a decentralized oracle network to allow blockchains to interact with external data feeds, events and payment methods in a secure way, providing the critical off-chain information needed by complex smart contracts to become the dominant form of digital agreement. 

It also expands the capabilities of smart contracts by enabling access to real-world data and off-chain computation while maintaining the security and reliability guarantees inherent to blockchain technology.

Thanks to Chainlink, you can use decentralization, trusted nodes, premium data, and cryptographic proofs to connect highly accurate and available data/APIs to any smart contract, as well as build on a flexible framework that can retrieve data from any API, connect with existing systems, and integrate with any current or future blockchain.

The Chainlink Network is driven by a large open-source community of data providers, node operators, smart contract developers, researchers, security auditors and more. The company focuses on ensuring that decentralized participation is guaranteed for all node operators and users looking to contribute to the network.

According to the Chainlink website you can “Securely connect smart contracts with off-chain data and services,” and “Chainlink decentralized oracle networks provide tamper-proof inputs, outputs, and computations to support advanced smart contracts on any blockchain.”At the time of writing, according to CoinMarketCap Chainlink’s price was US$19,57 with a 24-hour trading volume of US$1.004.829.874.
