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 solution if selected.

When a node is registered 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 and it 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.
