Reputation-Secured Oracle Infrastructure for Ergo
Turning oracle trust from an assumption into an on-chain, enforceable property.
KEEN is a fully decentralized, on-chain oracle reputation and incentive protocol built on the Ergo blockchain using the eUTXO model.
Unlike traditional oracle systems that rely on whitelists or assumed honesty, KEEN introduces verifiable reputation, slashing, and rewards, all enforced by smart contracts — without any backend, admin keys, or off-chain trust.
KEEN is designed to align with Ergo Oracle Pools (EIP-0023) and act as a reputation & accountability layer, not a replacement.
Decentralized applications depend on oracles — but:
- Oracle trust is often implicit, not enforceable
- Equal-weight oracle models ignore historical accuracy
- No transparent way to audit oracle behavior over time
- Incentives for long-term honest operation are weak
- Sybil attacks remain a threat in permissionless systems
KEEN solves this by making oracle correctness economically measurable, slashable, and rewarded — on-chain.
KEEN introduces a reputation-weighted oracle protocol where:
- Every oracle has a non-transferable on-chain identity
- Reputation increases only through correct submissions
- Incorrect or malicious data leads to slashing
- Oracle influence scales with historical accuracy
- Rewards accumulate without creating UTXO dust
- All logic is deterministic, auditable, and permissionless
- Oracle = wallet public key
- Identity represented by a unique NFT
- Identity cannot be transferred or duplicated
- Stored on-chain in a
ReputationBox - Starts at
0 - Increases with accuracy
- Decreases only via slashing
- Non-transferable, non-forgeable
- Uses reputation-weighted median
- Sorting done off-chain
- Verified on-chain using off-chain hints
- Fully permissionless aggregation
- Accuracy-based incentives
- Rewards accumulate inside the oracle box
- No per-epoch reward fan-out
- Withdrawable anytime by oracle
- Anyone can challenge incorrect aggregation
- Challenger posts a bond
- Valid dispute → oracle slashed
- Invalid dispute → bond forfeited
- All events recorded on-chain

All contracts:
- Follow eUTXO principles
- Use deterministic validation
- Contain strict invariants
- Avoid loops & heavy computation
- Require no admin privileges
KEEN is not a competitor to Ergo Oracle Pools.
Instead, KEEN provides:
- A reputation layer on top of existing pools
- Compatibility outputs matching EIP-0023 structure
- Drop-in replacement for dApps (NFT switch only)
- Optional deep integration for future pools
Existing dApps can adopt KEEN without rewriting contracts.
KEEN includes a fully client-side frontend:
- Wallet connection (Nautilus)
- Oracle registration
- Live reputation dashboard
- Price submission UI
- Aggregation trigger
- Dispute & slashing interface
- Reward balance & withdrawal
- React + TypeScript
- Ergo Explorer (read-only)
- Wallet signing for all actions
- No servers, no databases
