Fixed supply · zero premine · transparent, verifiable emission
Circulating supply is derived directly from the on-chain emission schedule and is independently verifiable against the node. Live values: /api/v1/supply.
| Ticker | BCBO |
|---|---|
| Maximum supply | 21,011,000 BCBO (hard cap, enforced by consensus) |
| Premine / ICO / presale | 0 / none / none |
| Decimals | 8 (1 BCBO = 100,000,000 base units) |
| Consensus / algorithm | Proof of Work / X16RV2 |
| Block time target | 600 s (10 minutes) |
| Halving interval | 210,000 blocks (~4 years) |
| Coinbase maturity | 100 blocks |
Issuance is deterministic and enforced by consensus. A short slow-start ramp applied to the earliest blocks, after which the subsidy is 50 BCBO, halving every 210,000 blocks.
| Block range | Block subsidy | Notes |
|---|---|---|
| 1 – 1,000 | 1 BCBO | slow start |
| 1,001 – 2,000 | 10 BCBO | slow start |
| 2,001 – 212,000 | 50 BCBO | full subsidy (epoch 0) |
| 212,001 – 422,000 | 25 BCBO | after 1st halving |
| 422,001 – 632,000 | 12.5 BCBO | after 2nd halving |
| … | halves every 210,000 blocks | → approaches 21,011,000 BCBO |
The first subsidy halving occurs at block 212,001. Successive halvings reduce the subsidy toward zero; total issuance approaches but never exceeds 21,011,000 BCBO.
Nota sul massimo: il tetto di 21.011.000 BCBO deriva dallo schema di halving da 21.000.000 (identico a Bitcoin) più gli 11.000 BCBO emessi nello slow-start dei primi 2.000 blocchi (1.000 × 1 + 1.000 × 10). Per l’aritmetica intera del consenso il totale esatto è 21.010.999,98 BCBO (così come il massimo reale di Bitcoin è 20.999.999,98, non 21.000.000). L’ultimo blocco con premio è il 6.932.000; dopo, il premio è zero per sempre.
| Miner reward | 47.5 BCBO — 95% of the 50 BCBO subsidy |
|---|---|
| Project reward | 2.5 BCBO — 5% of the subsidy |
| Project-reward window | blocks 2,001 – 209,999 only (~4 years); zero from block 210,000 onward |
| Project address | bb1q0rfr4ges48ruh8ej8fup65d65mfp3alvn2rhna |
The project reward is not a premine: these coins are mined block-by-block, are fully visible on-chain, and stop at block 210,000. The project address is controlled by Primaris Group S.r.l.s. and is auditable on the Treasury Transparency page (live balance and verification commands).
Total mined = the sum of all block subsidies according to the schedule above. Because no coins are created outside this schedule and none are provably destroyed, total supply equals total mined. Circulating supply is reported equal to total mined (a conservative definition that does not understate supply); the time-bounded project allocation is included and separately auditable at the address above. The figure is recomputable by anyone from the chain and is published at /api/v1/supply (bare number: /api/v1/circulating).
