Anyone in need of a blockchain enhancement solution to perform complex computations in standard programming languages
About Truebit
Truebit is a blockchain enhancement which enables smart contracts to securely perform complex computations in standard programming languages at reduced gas costs. While smart contracts can perform small computations correctly, large computation tasks pose security risks for blockchains. Truebit counteracts this shortcoming via a trustless, retrofitting oracle which correctly performs computational tasks. Any smart contract can issue a computation task to this oracle in the form of WebAssembly bytecode, while anonymous “miners” receive rewards for correctly solving the task. The oracle’s protocol guarantees correctness in two layers: a unanimous consensus layer where anyone can object to faulty solutions, and an on-chain mechanism which incentivizes participation and ensures fair remuneration. These components formally manifest themselves through a combination of novel, off-chain architecture and on-chain smart contracts.
