# Lido Legacy Oracle This contract is related to the Lido oracle, responsible for managing and reporting validator information and rewards. We have implemented handlers for the following events: * **Completed**: Handles completed oracle reports, capturing details like the epoch ID, beacon balance, and number of validators. * **PostTotalShares**: Records updates to the total shares and pooled Ether after oracle report processing. * **MemberAdded**: Logs when a new member is added to the oracle. * **MemberRemoved**: Logs when a member is removed from the oracle. * **ContractVersionSet**: Captures updates to the version of the oracle contract. * **QuorumChanged**: Handles changes to the quorum size required for oracle operations. * **BeaconSpecSet**: Records updates to the beacon chain specification parameters, such as epochs per frame, slots per epoch, and seconds per slot. * **BeaconReportReceiverSet**: Captures changes to the address of the contract that receives beacon reports. * **AllowedBeaconBalanceRelativeDecreaseSet**: Handles updates to the maximum allowed relative decrease in the beacon balance. * **AllowedBeaconBalanceAnnualRelativeIncreaseSet**: Captures changes to the maximum allowed annual relative increase in the beacon balance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
