The contract defines an event called InteractionLogged which records the address of the user (msg.sender) and the timestamp of the interaction (block.timestamp).
描述
The Proof of Interaction contract is a smart contract designed to log and track user interactions on the blockchain. It records each interaction with a timestamp, providing verifiable proof of engagement. This proof can be useful for various applications, such as tracking participation in decentralized applications (dApps), verifying activity on a platform, or ensuring transparency in engagement-based systems.
