Audit Layer

Truebit Verify uses a blockchain-backed Audit Layer to underpin its security model and enforce its core protocols. The Audit Layer performs several key functions:

Node Registry Smart Contract

NodeRegistry Address: 0x1e1802b2807FfE7fF22dCa24E8ff7d30a3a8150c

Node Registration is set up on the blockchain. It maintains a transparent list of all active Truebit Verify Nodes. Registered nodes can participate in the computation of a task's solution if selected.

When a node registers on the Node Registration Ledger, its unique Ethereum (ETH) address is added to the NodeRegistry smart contract's storage; similarly before the shutdown, it needs to de-register to ensure a graceful shutdown.

The NodeRegistry is an EVM-compatible smart contract manages the list of active nodes within the Node Registration Ledger. Each position on the list contains one registered Node Address.

Task Registry Smart Contract

TaskRegistry Address: 0x6825142A0e85dDB3cBf872a26eE2beefaedbc465

Task Registration is set up on the blockchain. It keeps a clear list of all registered and verifiable tasks. Once registered, tasks can be executed directly using the Truebit API's execute endpoint.

The TaskRegistry is an EVM-compatible smart contract that includes all necessary methods for managing namespaces and tasks, allowing anyone to register their deployed tasks.

Task Authorization Smart Contract

TaskAuthorization Address: 0x6da8eE7DF16BD92eb71F314f4b701C6c5b0b2721

Task Authorization is set up on the blockchain, maintaining a clear list of all authorized addresses that can execute tasks within a namespace. It also keeps a list of registered API_KEY hashes, allowing other users to execute tasks while making the user who registered the API_KEY responsible for the task execution payment.

The TaskRegistry is an EVM-compatible smart contract that includes all necessary methods for managing accesses over a namespace.
