Chainlink is effectively applying smart contracts to the offline world by creating different APIs which will be compatible with off-chain-based software.
Today, no one has been able to connect a smart contract with an external data feed. Solving this roadblock would be a big step forward for the world of blockchain, as it would provide many “low-tech” companies the ability to leverage the power of blockchain.
Chainlink aims to provide a solution as it is working on creating decentralized oracles which will allow non-blockchain based projects to interact with the Chainlink blockchain.
Chainlink has been staying under the radar, not hyping their project or putting too much time into marketing. However, with the announcement of partnerships with some well-known names in the crypto world such as Polkadot and Factom, people are starting to take notice.
