Chainlink is a decentralized oracle community that connects smart contracts via the blockchain and obtains resources outside the system. Some of these resources are bank accounts and web APIs, among others. These smart contracts have the ability to connect with external elements, making them more useful in the real world and creating greater value for users.
Chainlink's technology is based on a network of nodes or Chainlink Nodes (CN). This technology aims to feed the smart contracts that operate within the Ethereum network with the data it obtains from events in the non-virtual world.
