Checker Overview

Checkers are the validation side of the Pictor Network, responsible for verifying rendering outputs from Workers to ensure job accuracy while upholding the network’s integrity and quality.

Who are the Checkers?

Checkers are individuals or organizations who participate in the Pictor Network on the validation side of the rendering pipeline. They form the human role behind Checker Nodes, representing the community that helps uphold trust and reliability across the ecosystem. Unlike Workers, they don’t provide GPU compute but instead contribute by supporting the network’s quality assurance process.

What do the Checkers do?

Checkers are responsible for verifying rendering outputs submitted by Workers through the Checker Nodes. The tasks of Checker Nodes include:

• Checking outputs against job specifications (resolution, frame range, format, etc.)

• Identifying errors or discrepancies, such as missing frames or visual artifacts

• Approving valid results to release rewards to Workers, or flagging faulty outputs for reprocessing

By performing these tasks using Checker Nodes, Checkers help ensure job accuracy and preserve the overall integrity and quality of the network.
