Chainlink (LINK) has acquired the privacy-preserving oracle protocol DECO from Cornell University. The technology enables consumers and businesses to protect confidential data on the blockchain. "Basically, any smart contract that was previously limited by private data will soon be able to function on a public blockchain like Ethereum without revealing any confidential information to the blockchain," CEO Sergey Nazarov explained. LINK got a 10% price bump from the news but has pulled back since.
