With smart contracts increasingly dependent on AI, Truebit provides proven integration that you can trust.
Truebit Verify
Cloud-like simplicity, blockchain-grade security
Truebit Verify brings serverless compute backed by cryptographic proof to any blockchain application — from AI agents to tokenized assets.
Frictionless
Easily add verified tasks to any application
Develop, build, test, and deploy tasks instantly
- Serverless Function Tasks run your deterministic logic — in TypeScript, JavaScript, Python, Rust, or C++
- API Tasks provide read/write access to external data sources, including AI model APIs like Claude or OpenAI
- Go from CLI to a running, orchestrated oracle in minutes
Call tasks from anywhere with web services interface
- Integrate tasks directly into existing applications and data pipelines
- Create event-driven applications verified by Truebit
- Process files, transform data, retrieve information, and implement backend services
Verified output in less than a second
- Truebit Verify Nodes execute task code in parallel
- Task output and verification status provided immediately
- Transcripts are accessible to task givers at any time
Proof of task execution
- Truebit Certified Transcripts attest details of every task execution
- Inputs, outputs, code, and events are cryptographically signed
Secure
Verification guarantees compute integrity
Instant response
Multiple Truebit Verify Nodes execute each Truebit Serverless Function Task in parallel. The Truebit Verify Hub transparently routes tasks and checks results. If all nodes provide the same output, an initial verification result is returned for the Truebit task. Users can increase the number of Verification Nodes to provide greater integrity checks while maintaining an instant response.

Low-level checks
Low-level checks
If Truebit Verify Nodes return different results, a second verification round is needed. Each participating Truebit Verify Node is now subject to verification at the machine code level.
Notarized API execution
The Truebit Verify Hub executes API Tasks by directly calling an API endpoint. This keeps API credentials and data private. Truebit Verify Nodes use a shared session key to verify communication between the Hub and API endpoints.
This is the same mechanism that makes an AI model call auditable: the Hub calls the model directly, credentials stay private, and the exchange is notarized end to end — proof of what the model was asked and what it returned, not just that a call happened.

Attested results
Attested results
Each action taken to verify a Truebit Task is signed cryptographically by the Truebit Hub and Truebit Nodes who execute the code. These signed events are written to a Truebit Certified Transcript, which is hashed and rolled-up to a public blockchain.
Transparent
‘Trust no one’ architecture built for speed and connectivity
Blockchain-based audit layer ensures transparency
- Independent nodes provide limitless compute.
- High-performance hub connects tasks to nodes
- Node-to-node messaging and public ledgers combat hub censorship and collusion
Real-time connectivity
- Access Truebit Tasks via REST API
- Parallel task execution provides immediate, verified results
- Integrate offchain code with any blockchain app or smart contract
Instant transcripts, permanent attestations
- Transcripts provided immediately for every task
- Detailed transcripts kept private to protect sensitive data
- Attestable transcript hash rolled up on public ledger
