RFC-0008 — Oracle feed
Owner: Tokenomics Lead
What it defines
Price oracle for BME settlement. USD-per-OROG spot rate that drives mint/burn math.
Sources (4-source TWAP)
- Binance OROG/USDC depth-weighted spot
- Coinbase OROG/USDC depth-weighted spot
- On-chain DEX (post-listing)
- Uniswap V4 protocol-managed AMM
Window
- First 18 months post-TGE: 4–12h TWAP (red-team rule 10 — thicker liquidity needs longer smoothing).
- Month 19+: ratchet to 30 min.
Outlier handling
All 4 sources must agree within 5%. Outliers excluded. ≥2 outliers → fall back to static rate (last good rate from 24h ago) + freeze BME mint via pallet-bme::emergency_pause (multisig).
Oracle pool
Rotating set of ≥5 oracle operators. Separate stake pool from validators + watchers.
