# Internal Task Handler ## Overview The `InternalTaskHandler` contract on **L2** is one of the core component of the Othentic AVS framework handling [Internal Tasks](https://docs.othentic.xyz/main/learn/advanced-concepts/internal-tasks). It is responsible for processing and executing system-level tasks that are delegated by the `AttestationCenter`. These tasks include: * [Voting power synchronization](https://docs.othentic.xyz/main/learn/advanced-concepts/internal-tasks#sync-voting-power) * Voting power sync per task definition *** ## Core Functions #### getLastCommitBlockL1 ``` function getLastCommitBlockL1() external view returns (uint256); ``` Returns the block number of the last committed update from L1. #### getLastCommitBlockL2 ``` function getLastCommitBlockL2() external view returns (uint256); ``` Returns the block number of the last committed update from L2. #### attestationCenter ``` function attestationCenter() external view returns (IAttestationCenter); ``` Returns the address of the current `AttestationCenter` contract. #### processTask ``` function processTask(IAttestationCenter.TaskInfo calldata _task) external; ``` Processes a task from the `AttestationCenter`. Based on the [taskDefinitionId](https://docs.othentic.xyz/main/learn/core-concepts/tasks/task-definitions), the appropriate internal function is triggered: * [Voting Power Sync](https://docs.othentic.xyz/main/learn/advanced-concepts/internal-tasks#sync-voting-power) 10001 * [Voting Power Sync Per Task](https://docs.othentic.xyz/main/learn/advanced-concepts/internal-tasks#id-2.-voting-power-sync-per-task-definition) 10002 Access is restricted to the `ATTESTATION_CENTER` role. *** ### Task Handlers #### votingPowerUpdate ``` function _votingPowerUpdate(IAttestationCenter.TaskInfo memory _task) internal; ``` Handles voting power sync tasks. Decodes a `VotingPowerUpdate` struct and updates voting power for Operators using the OBLS contract. It also includes checks against duplicate or future block submissions. #### triggerInternalTransactionsTask ``` function _triggerInternalTransactionsTask(IAttestationCenter.TaskInfo memory _task) private; ``` Processes internal OBLS-specific administrative transactions to update voting power per task for restricted operators. This is restricted only to certain method selectors on the OBLS contract. --- # 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.
