Chainlink is a decentralized blockchain-powered platform that enables secure and reliable smart contract-based transactions by connecting smart contracts with off-chain data sources and external systems.
Chainlink was founded in 2014 by Sergey Nazarov and Steve Ellis.
The Chainlink ICO was launched in 2017 and raised $32 million.
Chainlink has partnered with numerous companies and blockchain projects including Google, Oracle, Gartner, SWIFT, and more.
As of June 2021, Chainlink has a market capitalization of over $14 billion.
Band Protocol is a decentralized oracle platform that enables smart contracts to access real-world data in a secure and reliable manner.
DIA is a decentralized oracle platform that delivers transparent and reliable financial market data to blockchain-based applications.
Chainlink Core is the main software that powers the Chainlink network and allows developers to create secure and reliable smart contract-based applications.
Chainlink VRF (Verifiable Random Function) is a built-in cryptographic tool that enables the generation of secure and unbiased random numbers on the blockchain.
Chainlink is a decentralized blockchain-powered platform that enables secure and reliable smart contract-based transactions by connecting smart contracts with off-chain data sources and external systems. Chainlink has its own cryptocurrency (LINK) which is used for paying network fees and rewarding node operators.
In the context of Chainlink, an oracle is a decentralized service that connects smart contracts with off-chain data sources and external systems. Oracles are used to retrieve and verify real-world data and events, and provide them to smart contracts.
Chainlink enables developers to create smart contract-based applications that can securely and reliably interact with external systems and real-world data sources. This makes it possible to create decentralized applications in various industries such as finance, insurance, healthcare, and more.
Node operators are responsible for providing off-chain data to smart contracts and ensuring the accuracy and reliability of the data. They are rewarded with LINK tokens for their services. Node operators can be individuals or organizations who have the technical knowledge and infrastructure to run the Chainlink software.
Chainlink uses various security measures including decentralized architecture, multiple data sources, customizable oracle networks, and secure randomness generation (via VRF) to ensure the security and reliability of its network. Chainlink also has a bug bounty program and undergoes regular security audits to identify and fix potential vulnerabilities.
