About Augur

Augur is a decentralized oracle. It tells apps on the blockchain what happened in the real world.

It launched on Ethereum in 2018 as a prediction market. Since 2025 the Lituus Foundation has led its restart, and the work now centers on Augur Lituus, one of the next versions of Augur’s oracle.

No company or committee should hold the final word on what happened.

Augur was built on that position from the start, and Augur Lituus is too.

Knowledge of the world is spread across many people, and no central authority can gather all of it without bias. So Augur’s answers come from the people who know, with something to lose if they are wrong.

The story so far

Over a decade on Ethereum, from a prediction market to an oracle for any app.

  1. The crowdsale

    Augur holds one of Ethereum’s first crowdsales to fund a decentralized prediction market.

  2. Live on Ethereum

    Augur launches on mainnet. REP holders settle disputed outcomes, and a fork is the last resort.

  3. The restart

    Long-time Augur community members restart the project in public as the Lituus Foundation, stewards of Augur’s treasury.

  4. Generalized Augur

    A draft proposal, shared for comment, for a universal and permissionless oracle that any application can ask.

  5. The whitepaper

    The Augur Lituus whitepaper sets out how the oracle works, with a comparative analysis of oracle security.

  6. The Moon Fork

    A dispute over whether NASA’s Artemis II lifted off escalated all the way to a fork: the first full run of Augur v2’s fork on Ethereum mainnet. When migration closed on 3 August, Yes had won.

    99.97%of migrated REP moved to Yes, the answer that matched what happened.

    Building Augur Lituus

    The core question flow is in place, and the work now focuses on disputes and forking.

Who does what

The Lituus Foundation funds independent teams to build Augur. Neither the Foundation nor the teams decide what the oracle answers.

Decides the answers

Anyone with REP at stake

Anyone can report what happened or challenge a report by putting REP behind it, and a fork is the last resort. No one holds a backstop or veto over Augur Lituus answers, the Foundation included.
