Computing Provider

A Computing Provider (CP) is a third-party individual or organization that offers scalable computing resources, which businesses can access on demand over Swan network. These resources include cloud-based compute, storage, platform, and application services.

As a resource provider, you can run a ECP (Edge Computing Provider) and FCP (Fog Computing Provider) to contribute yourcomputing resource.

• ECP (Edge Computing Provider) specializes in processing data at the source of data generation, using minimal latency setups ideal for real-time applications. This provider handles specific, localized tasks directly on devices at the network’s edge, such as IoT devices. At the current stage, ECP supports the generation of ZK-Snark proof of Filecoin network, and more ZK proof types will be gradually supported, such as Aleo, Scroll, starkNet, etc. Check Install Guideline here.

• FCP (Fog Computing Provider) Offers a layered network that extends cloud capabilities to the edge of the network, providing services such as AI model training and deployment. This provider utilizes infrastructure like Kubernetes (K8S) to support scalable, distributed computing tasks. FCP will execute tasks assigned by Market Provider, like Orchestrator on the Swan chain.

Address Types

A CP account has three different wallet addresses to ensure security and separation of responsibilities:

• ownerAddress: This is the owner account of the CP account. The owner has permission to change account information such as the multi-address, worker address, and beneficiary address. In most situations, the private key of the ownerAddress does not need to be present on the server for security reasons.

• workerAddress: This is the actual working address used for submitting proofs (submitProof). It needs to be funded with a certain amount of ETH to pay for gas fees when submitting proofs.

• beneficiaryAddress: This is the address where all earnings from the CP account will be sent. It is solely used for receiving funds. For security purposes, the private key of the beneficiaryAddress should not be stored on the server to maintain isolation.

By separating these address, the system ensures that only the necessary workerAddress private key is present on the server, while the more sensitive ownerAddress and beneficiaryAddress private keys are kept separate, enhancing the overall security of the system.

Exit Procedure for a Computing Provider (CP)

If a CP wishes to exit and stop providing computing services, two steps are required:

Step 1

Set the taskTypes to exit status (taskTypes = 100). The specific command is:

Execute the following command:

computing-provider --repo <YOUR_CP_REPO> account changeTaskTypes --ownerAddress <YOUR_OWNER_ADDRESS> 100

Step 2

Withdraw collateral from both Collateral and Escrow accounts. The amount in the Collateral account can be directly withdrawn, while the amount in the Escrow account requires 7 days to complete the withdrawal. The process is as follows:

For an ECP:

To withdraw from the Collateral account:

computing-provider --repo <YOUR_CP_REPO> collateral withdraw --ecp --owner <YOUR_WALLET_ADDRESS> --account <YOUR_CP_ACCOUNT> <amount>

To withdraw from the Escrow account:

Submit withdrawal request:

computing-provider --repo <YOUR_CP_REPO> collateral withdraw-request --ecp --owner <YOUR_OWNER_ADDRESS> <AMOUNT>

Confirm withdrawal (after 7-day waiting period):

computing-provider --repo <YOUR_CP_REPO> collateral withdraw-confirm --ecp --owner <YOUR_OWNER_ADDRESS>

For an FCP:

To withdraw from the Collateral account:

computing-provider --repo <YOUR_CP_REPO> collateral withdraw --fcp --owner <YOUR_WALLET_ADDRESS> --account <YOUR_CP_ACCOUNT> <amount>

To withdraw from the Escrow account:

Submit withdrawal request:

computing-provider --repo <YOUR_CP_REPO> collateral withdraw-request --fcp --owner <YOUR_OWNER_ADDRESS> <AMOUNT>

Confirm withdrawal (after 7-day waiting period):

computing-provider --repo <YOUR_CP_REPO> collateral withdraw-confirm --fcp --owner <YOUR_OWNER_ADDRESS>

Notes

• It’s recommended to perform Step 2 (withdrawing from Escrow) 24 hours after completing Step 1, as the engine periodically settles CP accounts. This includes actions like locking collaterals, slashing collaterals, sending UBI rewards, etc., all of which may impact the success rate of your withdrawal.

• After completing Step 1, the CP will no longer receive any tasks, including UBI tasks and regular AI tasks.
