Today, we are excited to officially launch Truebit Verify in Open Beta, marking an important milestone in our journey towards creating a more transparent and trustworthy blockchain ecosystem. Starting with the groundwork we laid for optimistic rollups more than a decade ago, Truebit has remained focused on our founding vision: bringing transparency and trust to data processing that takes place outside of smart contracts.
As real-world asset tokenization grows toward a multi-trillion dollar market and AI systems increasingly drive market-moving decisions, the need for transparency has become increasingly urgent. Offchain code execution – which powers the majority of decentralized applications – creates significant trust gaps that jeopardize growth in these emerging markets.
Truebit Verify fills the critical infrastructure gap between real-world, offchain systems and on-chain transactions. Our verified compute platform allows otherwise untrusted data to be securely integrated into blockchain applications. This launch marks a significant step forward in creating a digital asset ecosystem that maximizes liquidity and reliability by tackling the risks inherent to trustless, automated trading.
Powering a Verified Economy – The Transparency Gap
Today’s consumers rely more on reputation than proof. In our envisioned, verified economy, trust is embedded in every digital interaction. At its core, Truebit Verify is built on the idea that every computation – whether it’s executing complex business logic, integrating external APIs, or moving data between blockchains – should be verifiable.
While blockchains excel at creating transparent, immutable ledgers, the reality is that the vast majority of decentralized application code runs outside of smart contracts. Blockchains may record key transactions, but the complex business logic, API integrations, and data processing that power modern applications happens offchain – often in opaque, centralized environments that users must simply trust.
Truebit Verify rebalances this equation by extending blockchain-level transparency to offchain computation, creating an auditable trail of every process that influences on-chain outcomes.
Integrity for Offchain Dependencies
New technologies like agentic AI, RWA tokenization and decentralization introduce a trust crisis as complex offchain dependencies and data sourcing bring reliability of data and computations into question. Truebit Verify mitigates integrity gaps with verified function execution and verified API access. Transcripts provide proof of function task execution, and also create a verifiable record of API tasks, including inputs, outputs and TLS session metadata.
Human-Readable Proofs
SNARK proofs, though succinct, remain inherently opaque to human observers. In contrast, interactive proofs — like those used in Truebit verification — offer a more human-readable proof. Truebit Verify’s interactive proofs complement zero-knowledge systems by preserving verifiability and understandability — a critical tradeoff when offchain computation intersects with real-world trust. Indeed, one needs not only proof of correct execution but also proof the code in question does what’s expected.
Truebit Verify’s Certified Transcripts establish transparent, verifiable, records of task executions and API calls, providing a comprehensive and immutable audit trail that details the code, inputs, outputs, and selected identities. Transcripts offer proofs across versatile messaging mediums, from smart contracts to email.
Beyond Beta
Open beta is a huge milestone for the Truebit Verify team, but we know that this is just the beginning of the journey we’ve embarked on in establishing the Verified Economy. Based on feedback from our users, we expect our roadmap to include the following areas of focus:
- Truebit Verify for Smart Contracts. Today, developers can integrate Truebit tasks as RESTful web service calls into their applications. This is a flexible integration pattern that has allowed our early access developers to bring transparency into the Web2 backends that power their blockchain transactions. While our pattern also allows for smart contract integration using Web3.js and other developer frameworks, we believe that extending smart contracts with Truebit can accelerate the growth of decentralized applications by eliminating the need for opaque backends. For example, one could upload JavaScript code into a smart contract and then instantly execute it as a Truebit task.
- Privacy-preserving verification. Truebit’s super power is transparency – and while transparency is the exact right answer for many verification use cases, some data needs to remain private even from the verification layer. An amazing amount of progress has been made in privacy preserving verification recently, with pragmatic use of ZK proofs now a reality. We see ZK proofs as a complementary technology to Truebit-style verification, and our team is already working on adding ZK proofs as a verification option in our platform. We anticipate piloting ZK proofs, alongside additional API proxying options, in the next version of API Tasks.
- Complex task workflows. Truebit tasks allow you to create atomic-level proofs of correctness. As you start to build more tasks, there are cases where you may want to pass the output of one task as the input to another downstream task. While you now can coordinate the execution of multiple Truebit tasks in their own application code, our roadmap includes an important feature called Metatasks that allows dependencies between tasks to be managed directly by the Truebit Verify platform.
- Support for more languages. Truebit Verify already executes code in Python, JavaScript, C++, and Rust, and we plan to roll out support for additional compiled and interpreted languages.
- Enhancing Human Readable Proofs with Attestations. Truebit Verify’s Certified Transcripts provide human readable, proof of correctness for compute tasks and API calls. But it’s not good enough for human readability to be limited to application developers who can interpret computation proofs. Non-technical users also need a way to link compute tasks to the information they are seeking to verify. We see attestations – essentially signed statements swearing to the accuracy of a given piece of data – as the missing link between verified compute and verifiable data. As such we plan to expand Truebit Certified Transcripts to include Attestation metadata and support the Ethereum Attestation Service.
- Truebit Decentralized Compute Network. Since our earliest days, Truebit has been focused on making decentralized compute safe and scalable. As we continue the rollout of Truebit Verify, we will be carefully expanding our compute network and ultimately opening it fully to independent node operators in order to maximize the quality of trustlessness verification. Like most new infrastructure projects, we are moving deliberately through this network expansion phase in order to ensure the highest security standards are being met. To find out more about how Truebit Verify ensures the integrity of compute transactions when faced with the reality of byzantine node behavior, be sure to read the Truebit Unchained technical report.
We will be discussing each of these enhancements in greater detail over the coming weeks and months. Stay tuned!
