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.
