Smart Contracts provide the ability to execute tamper-proof digital agreements, which are considered highly secure and highly reliable. In order to maintain a contracts overall reliability, the inputs and outputs which the contract relies on also need to be secure. Chainlinks provide a reliable connection to external data, that is provably secure end-to-end.
Connecting your smart contracts to the inputs and outputs it needs.Building a truly valuable smart contract requires the use of multiple inputs to prove contractual performance, as well as multiple outputs to affect outside systems and/or send payment to complete the smart contract. Chainlink provides your smart contract with the inputs and outputs it needs to reach its full potential.
