34. A smart contract is an agreement whose execution is both automated and enforceable.
• The actual “transaction” among parties is expressed through and independently
executed by computer code, no party can block it or otherwise tamper with.

the facts shared among them, which are governed by the program.
• Used to satisfy
• common contractual conditions,
• lower transaction costs and risk, and
