- Storage: The contract stores data and permanently saves it on the blockchain.
Features of Ethereum contracts:
- Immutability: After a contract is deployed, its code or data cannot be changed.
- Autonomy: The contract automatically executes its predefined rules without human intervention.
- Transparency: Contract code and data are publicly visible on the blockchain for anyone to view.
