Phi-Halving Schedule
Block rewards decrease by dividing by φ (1.618...) every 15,474,020 blocks (~1.618 years). Once the phi-halving reward drops below 0.1 QBC (at era 11), tail emission of 0.1 QBC/block ensures the full 3.3B supply is eventually mined over ~2,770 years.
| Era | Reward (QBC) | Years | Supply Mined |
|---|---|---|---|
| 0 | 15.27 | 0 – 1.6 | ~6.0% |
| 1 | 9.44 | 1.6 – 3.2 | ~9.7% |
| 2 | 5.83 | 3.2 – 4.9 | ~12.0% |
| 3 | 3.60 | 4.9 – 6.5 | ~13.4% |
| 4 | 2.23 | 6.5 – 8.1 | ~14.3% |
| 5 | 1.38 | 8.1 – 9.7 | ~14.8% |
| 10 | 0.14 | 16.2 – 17.8 | ~15.5% |
| 11+ | 0.10 (tail) | 17.8+ | → 100% |

Fee Pricing Modes
oracle_pegFees auto-adjust to a USD target via the on-chain oracle. Default.
fixed_qbcFixed QBC amount. Fallback when the oracle is unavailable.
direct_usdUSD target via an external price feed. Emergency fallback.
