Event logs are records that track specific occurrences within a blockchain or a decentralized application. They serve as a detailed history of actions taken, such as transactions, contract executions, and changes in state.These logs are particularly useful for developers and users who want to monitor activities or debug issues. For instance, when a smart contract is executed, the event logs capture important data related to that action, such as the involved addresses, amounts transferred, or any relevant parameters.Event logs are essential for transparency and accountability. They allow users to verify that actions have been carried out as intended, providing a clear trail of what happened and when. Since they are stored on the blockchain, they are immutable, meaning they cannot be altered or deleted, further cementing their role in ensuring trust.Overall, event logs offer both functionality and transparency, enhancing the user experience and improving the reliability of blockchain applications.
