A scalable verification solution for blockchains

Secure, scalable, decentralized computation.

TrueBit gives Ethereum smart contracts a computational boost. Don't let Ethereum's gas limit drag your imagination! A novel incentive structure guarantees fast, reliable, and affordable results without third-party trust.


TrueBit integrates with existing technology. Here's what's in store.

A community cloud you can trust. Offer rewards in exchange for computational tasks, or get paid for providing correct solutions.
bullet Dogether. Add smart contract functionality to your cryptocurrency, or trade its tokens without an exchange.
bullet Scalable "on-chain" storage. Store data on Swarm or an external blockchain, and then use it as input for smart contracts.
Increase transaction throughput. Build your own cryptocurrency with high transaction volume.
bullet Interact with miners like never before. Introducing smart contracts that can check any proof-of-work.
bullet Decentralized streaming video via Livepeer.
bullet Autonomous machine learning including the ArtDAO and vision-enabled smart contracts.
bullet Data marketplace. Trustless verification and remuneration for data models. See also Numerai and Ocean .
Democratic Hypercatallaxy, Lexon, Consortium Chains, and other Mind-blowing combos.

The Verifier's Dilemma, discovered by TrueBit's founder together with Loi Luu, Raghav Kulkarni, and Prateek Saxena in 2015, limits miners' incentives to process transactions. TrueBit bypasses this bottleneck.


Jason Teutsch is a mathematician and computer scientist whose research focuses on distributed systems security, game theory, and algorithmic randomness. He has held postdoctoral positions at National University of Singapore, Penn State, and Universität Heidelberg, research positions at think tanks RAND and IDA, and multiple Fulbright fellowships.
Whitepaper Coauthor

Christian Reitwiessner plays an active and pivotal role in the development and maintenance of Ethereum. In addition to researching future directions for the Ethereum community, he led the development of Solidity, the language of Ethereum smart contracts, as well as cpp-ethereum, a client application required to run the network.
Chief Operating Officer

Robbie Bent co-founded startups in North America and Israel which delivered complex hardware products in the energy harvesting and telecommunications spaces. He has deep experience in building technical teams. Robbie is obsessed with building products that improve the scalability of smart contract platforms as well as growing a scalable, open source community.
Senior Core Developer

Sami Mäkelä's research and development focuses on smart contracts, formal verification, and software metrics. Since completing his PhD in spring 2016, Sami has been working on formal verification of Ethereum Virtual Machine programs. As a student, he participated on a team which performed a security audit on a Finnish e-Voting pilot.
Engineering Lead

Sina Habibian works on the design and development of cryptoeconomic protocols at Truebit. He previously built the data platform at Omada Health, did computational physics at the Max Planck Institute, and ran a software engineering consultancy. Sina also enjoys backpacking, meditating, and reading.
Core Developer

Farzad Sadeghi lives in a gnome terminal. He is a software enthusiast who likes writing code, sometimes a little too much. Farzad comes from a safety-critical embedded software background and thinks the best kind of code is the kind that takes software as input and outputs another software. The more code, the better. When he is not working on TrueBit, he is either playing (gz)doom, listening to music, and/or writing code.
General Counsel

Florian Glatz has worked full-time as a lawyer, software developer, and academic researcher in the blockchain space since 2013. As a lawyer and researcher, he navigates the uncharted waters of smart contracts and cryptocurrencies in a world of legacy legal systems. As a software developer, Florian focuses on software-driven innovation in law and finance.

Ryan Zurrer is Principal and Venture Partner at Polychain Capital where he leads private investments and helps projects structure their token offerings. Ryan has been an active angel investor in the blockchain ecosystem since 2012, and he ran a Bitcoin mining operation throughout 2013. Previously he was CEO of a Brazilian renewables firm and managed their 958MW portfolio.

Trent McConaghy and his colleagues at BigchainDB & IPDB are building a shared database for the Internet, for sovereign personal data, and to fairly compensate creators. His AI research has helped drive Moore's Law, reconcile human and machine creativity, and ensure humanity's role in an increasingly autonomous world. Trent advises Estonia's E-residency program.
