Node operators extract data from off-chain API data feeds and convert it into blockchainĬompatible formats to trigger smart contracts. To provide a fully decentralized oracle network, Chainlink depends on independent node Them securely via APIs to off-chain resources, such as market, financial or legal data,Įvents, back-end systems, other blockchains or any other web API available. Resources such as blockchain networks (Ethereum, Hyperledger etc), and connecting Chainlink acts as aĭecentralized oracle infrastructure, with the core functional objective being toīridge the on-chain and off-chain world using APIs.
The solution is Chainlink, a secure blockchain middle-ware. Or other resources that run outside of the network in which the agreements are executed. The most debated shortcoming ofĭecentralized systems, stems from the inability of digital agreements (smart contracts) to Today, at the forefront of the fourth industrial revolution oracles are again at the center of attention.ĭistributed ledger technology suffers from what it is called the “oracle problem”. The link between two worlds.įor thousands of years the Oracle of Delphi was the single most influential political and social figure in the ancient world. The sole purpose of the Oracle of Delphi was to share a glimpse of the future, being filled by the spirits of gods. the origins - heritage - principles - vision In Ancient Greece, no major decision was made without consulting the Oracle of Delphi.įrom the lowliest peasants to dignitaries, leaders and kings, everybody traveled to Delphi for a chance to ask Pythia, the oracle, a question.
