# Copy of Checker Nodes
## Checker Node Overview
1. **What is the Checker Node?**
**Checker Node** is one of the core products in the Pictor Network, acting as the trust and validation layer of the decentralized compute ecosystem.
While **Worker Nodes** supply computing 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 Workers, making sure the results are correct and reliable before they are finalized.
2. **How do the Checker Nodes Work?**
**Checker Node Operation**
Every rendering job submitted to the Pictor Network must pass a validation step before the Creator receives the final results. Checker Nodes perform this process by confirming that Worker outputs are valid, consistent, and free from manipulation. This mechanism ensures that rendering on Pictor Network remains **transparent, decentralized, and dependable**.
**NFT Staking Mechanism**
Checker Nodes operate through an **NFT staking mechanism**. Holders of Pictor Checker Node NFTs can stake them in Checker Nodes, turning their NFTs from digital assets into infrastructure components.
Checker Nodes become operational through NFT staking:
* Each node has **200 staking slots**.
* Users may stake one or multiple NFTs into a chosen node.
* A node requires at least **30 staked NFTs** to become **Active** and start validating jobs. Nodes with fewer than 30 NFTs remain **Inactive** and cannot participate in validation.
This staking mechanism ensures that only nodes with sufficient community support can participate, aligning responsibility with incentives.
**Epoch-Based Rewards**
Checker Nodes earn rewards on an **epoch basis** (currently defined as ***one week***).
* For every rendering job, **10% of the Creator’s rendering payment** is allocated to the Checker Node that verified the job.
* The total rewards accumulated by a Checker Node during an epoch; therefore, depend on the **number of jobs it successfully verifies**.
At the end of each epoch, these rewards are distributed to the node’s NFT stakers (known as **Checkers**):
* Distribution is proportional to the **number of NFTs** each user has staked in that node.
* Rewards also account for the **duration that NFTs remained staked** within the epoch (*NFTs staked later in the epoch receive a smaller share*).
All rewards are fully transparent and can be monitored through the **Checker Node Dashboard.**
## Checker Node Dashboard
The **Checker Node Dashboard** on **Pictor Cloud** serves as the control center for monitoring and managing all Checker Nodes within the Pictor Network. The Dashboard provides full transparency into node activity, staking status, and rewards.
Importantly, you don’t need to stake NFTs to access the dashboard. All key details about Checker Nodes are public and accessible to any user.
1. **Tab: Checker Nodes**
Displays the full list of Checker Nodes in the network.
Key information includes:
* **My Staked Nodes** – the number of Checker Nodes you have staked into.
* **Claimable Rewards** – rewards available to claim.
* **Node Details** – by clicking the 👁 icon, you can view detailed data such as:
* Total number of jobs verified.
* Jobs verified per epoch.
* Transaction hash, status, and validation time.
2. **Tab: My NFTs**
This tab lets you manage all your Pictor Checker Node NFTs, organized into two sub-tabs:
* **Available:** List of NFTs you own but haven’t staked yet, and the Interface to select a Checker Node for staking.
* **Staked:** List of NFTs currently staked into Checker Nodes.
Checker Nodes form the trust layer of Pictor Network, ensuring every render result is validated. To be part of this backbone, you can stake through **Checker Node NFTs**.
