LINK ChainLink

LINK is an ERC20 standardized token based on the Ethereum blockchain. It is used to pay Chainlink node operators to retrieve data from off-chain data, format the data into a blockchain-readable format, off-chain computing, and ensure normal operation time. Chainlink tokens are part of the running node to prevent bad participants. 1. The project introduces the first decentralized Oracle network that allows anyone to safely provide smart contracts, access key external data, offline payments and any other API functions. Any user with a data feed, offline service (such as local payment) or any other API can directly provide it to the smart contract in exchange for LINK tokens. The ChainLink network is a distributed network of ChainLink nodes. They all directly convey the use of specific data, APIs and various offline payment functions to smart contracts. The Chainlink network consists of two independent parts, on-chain and off-chain, they must interact to provide services. The network is constructed in such a way that it can be upgraded so that its different components can be replaced when better technologies and technologies emerge.
