Buy Chain Link (LINK)

The idea behind San Francisco-based Chainlink is to connect smart contracts through blockchains, allowing them to access key off-chain resources, such as bank account payments, data feeds or webAPIs; Developer interest is focused on creating smart contracts that can interface with external systems to make them useful in the business world.

The place where blockchain meets the outside world was a huge vulnerability in decentralized applications (dapps) until Chainlink created a secure bridge. The points where data enters the blockchain are also points where data can be tampered with, compromised, or simply tampered with - these points of failure are where Chainlink creates value.
