Ricardian contract

A Ricardian Contract is a type of agreement that is written in both human-readable language and computer-readable language. This is so that people and computers can both understand and agree to the terms of the agreement. This is used a lot in blockchain, which is a digital ledger that records all types of digital transactions. The Ricardian Contract helps make sure that everyone involved in a transaction understands what they're agreeing to and is able to enforce it. So, it's like a contract that both people and computers can understand, and use to make sure everyone involved in a transaction is doing what they agreed to.
