Keepers

In the TriggerX architecture, keepers play a crucial role as performers and attesters, responsible for executing and validating automation tasks in a decentralized manner. These keepers ensure that smart contract functions are triggered based on predefined conditions, such as time-based, event-based, or condition-based automation.

Role of Keepers in TriggerX

Keepers function as both performers and attesters in the network. Their primary responsibilities include:

1. Task Execution (Performer Role)

• When a task is assigned to a keeper, it executes the smart contract function as specified in the job definition.

• The task execution may require fetching real-time data from on-chain or off-chain sources (e.g., price feeds from an API or data from IPFS).

• Once the execution is completed, the keeper generates a Proof of Task (PoT), a cryptographic proof confirming the successful execution of the assigned job.

2. Attestation (Attester Role)

• Since TriggerX operates as an AVS (Actively Validated Service), all participating keepers act as attesters.

• Multiple keepers validate the correctness of executed tasks by checking the Proof of Task (PoT) submitted by other keepers.

• The attestation process involves a quorum-based approach where a threshold number of attestations is required before finalizing the execution result.
