A chain of decentralized oracle networks, supplying secure and reliable data feeds for smart contracts. Smart contracts are self-executing contracts on blockchains; however, most of the time, they are in dire need of access to external sources of data. Chainlink solves this chasm by providing a secure way for smart contracts to access off-chain data.
Why consider it?
Smart contracts can disrupt a lot of industries, but the need for reliable external data will act as a stumbling block. In that sense, Chainlink contributes to a decentralized oracle network; hence, it will make a high difference in smart contract applications.
DeFi and blockchain tech are only going to get much bigger in the future. In a couple of years, when people will realize that they need secure and reliable oracles, Chainlink will be used largely.
