Chainlink was launched by San Francisco fintech company SmartContract in June 2017, and developers described it as a secure blockchain middleware designed to allow smart contracts to access key off-chain resources such as data streams (databases), websites ( WeChat, Taobao, etc.) API, and traditional bank (Alipay, WeChat payment, etc.) account payments. The ChainLink network is a distributed network of ChainLink nodes, all of which directly transfer the use of specific data, APIs, and various offline payment functions to smart contracts. The Chainlink network consists of two separate parts, on-chain and external, and they must interact to provide services. The network is structured in such a way that it can be upgraded so it can replace its different components as better technologies and techniques emerge. The on-chain components of the network filter the oracles through service level agreements (SLAs) based on metrics requested by one party of the smart contract. Using these metrics, Chainlink collects responses to SLA queries, ranks them using reputation and aggregation models, and provides the final set of results for Chainlink queries that may be implemented into smart contracts. Chainlink’s token LINK sales cap is $ 32 million, with a total supply of 1 billion. 35% of all LINK tokens will incentivize the ecosystem through node operators and sell an additional 35% in public token sales. The last 30% of the total number of LINK tokens will remain with the company for continued development and employee payments.
