Truebit Verify​

Cloud-like simplicity, blockchain-grade security

Truebit Verify brings serverless compute to the decentralized world of Web3.


Easily add verified tasks to any application

Develop, build, test and deploy tasks instantly

Call tasks from anywhere with web services interface

Verified output in less than a second

Proof of task execution

Bringing transparency to offchain compute


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. The Truebit Verification Game determines fault by challenging Nodes to prove individual computational steps.

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. 

Notarized API execution

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. 

Connect. Secure. Innovate.

Open your Web3 application to the full universe of data and provide immutable proof of execution for even the most complex functions.
