Checker Nodes Overview

What is a Pictor Checker Node?

Pictor Checker Node is one of the core nodes in the Pictor Network, acting as the trust and validation layer of the decentralized compute ecosystem.

While Worker Nodes supply GPU compute power to process rendering jobs, Checker Nodes focus on ensuring the accuracy and integrity of rendered results. They do not perform rendering themselves; instead, they verify the outputs produced by Worker Nodes, ensuring the results are correct and reliable before they are finalized and sent to the rendering customers.

The Importance of Checker Nodes

Checker Nodes play a critical role in maintaining the trust and integrity of the Pictor Network:

• Quality assurance: Every job is validated before being finalized, ensuring reliable results for users.

• Security & transparency: Verification is performed in a decentralized manner, preventing single-party control or tampering.

• Incentive alignment: Participants who help operate (stake in Checker Nodes) are rewarded, creating strong economic motivation to keep the system secure and trustworthy.

Checker Node Types

There are six types of Checker Nodes in the Pictor Network, each corresponding to one tier of Checker Node NFT — Bronze, Silver, Gold, Platinum, Titanium, and Iridium.

Each node type serves as a dedicated staking pool for its matching NFT tier.

For example,

• A Silver Checker Node only accepts Silver-tier NFTs.

• A Gold Checker Node only accepts Gold-tier NFTs.

This one-to-one structure keeps the staking process organized and ensures the system remains transparent and balanced.
