What Is the Role of a Blockchain in Executing Smart Contracts?

A blockchain serves as the decentralized and immutable foundation for executing smart contracts. It acts as a distributed ledger that records all transactions and contract states, ensuring transparency and security.

When the conditions of a smart contract are met, the code is executed by the network of nodes on the blockchain. The result is then permanently recorded, preventing tampering or censorship.

This removes the need for a central authority to validate or enforce the contract's execution.
