Quick take - Smart contracts
Smart contracts are tamper-proof programs on blockchains that facilitate automatic transactions by using conditional software logic such as, “if x is true, then execute y".[1]
“Smart contracts are digital agreements that exist as an immutable software program on the blockchain with conditions attached to its execution.” - (Source: What Is a Smart Contract? (https://chain.link/education/smart-contracts))
