JunoReality

A CosmWasm port of Reality.eth — a bond-escalating crowdsourced oracle for contested social facts. Arbitration is pluggable; v1 ships first-class adapters for Juno chain governance and DAO DAO DAOs (no Kleros).

Credit & inspiration

JunoReality is a port — the mechanism design isn't ours. Bond escalation, the right-answer redistribution rule, the history-hash chain, the arbitrator-as-address permission model, the UNRESOLVED_ANSWER semantics — all of it comes from Edmund Edgar and the Reality.eth contributors (reality.eth, RealityETH/reality-eth-monorepo). The canonical reference we ported against is RealityETH-3.0.sol at commit b996b0a0.

We also lean on the wider bond-escalation-oracle literature that informed Reality.eth: Augur's REP dispute rounds, UMA's optimistic oracle, and Kleros' juror-bond mechanics.

cw-reality is a clean-room reimplementation under Apache-2.0. Reality.eth itself ships under GPL-3.0; this port studied the source for behavioural equivalence but does not copy code. Where docs cite line numbers in RealityETH-3.0.sol, those are pointers for auditors verifying the port, not licensed inclusions.

Substantial differences from Reality.eth

Most of the mechanism is preserved literally — the Alice/Bob/Carol worked example from the Reality.eth whitepaper produces identical payouts here. The deltas (multi-denom denom binding, contract-level timeout floor, dispute round cap, sha-256 history hash, explicit state enum, cw-filter answer schemas, removal of commit-reveal) are catalogued in:
