No over-paying blocks
A block that pays its miner more than the schedule allows is rejected by every node.
Coinomics
Fixed supply. No surprises.
Apart from a one-time launch allocation in block 1, every BITS is created by mining. The block reward halves every five years, and the total can never exceed about 21.09 billion BITS.

- Reward per block

Enforced by GetBlockSubsidy() in src/validation.cpp. A block that pays itself more is rejected by every node.
01 · How coins are created
Mined, not printed.
After one launch allocation, the only way new BITS appear is a miner finding a block. Here's the whole schedule.
-
0
Genesis block
1,000 BITS
Can never be spent, the same as in Bitcoin.
-
1
Block 1
67,500,000 BITS
A one-time launch allocation. More below.
-
2+
Block 2 onward
1,000 BITS / block
With a new block every 15 seconds.
-
½
Every 10,512,000 blocks
Reward halves
Exactly every 5 years: 1,000, then 500, then 250, and so on.
-
64
After 64 halvings
Rewards end
New coins stop. Miners earn transaction fees only.

One BITS splits into 100,000,000 base units (8 decimal places), just like Bitcoin.
02 · Supply over time
Half of all BITS in five years.
Supply grows fast at first, then flattens with every halving as it approaches the cap. At the current rate, the network mints 5,760,000 BITS a day.
Total BITS in circulation
Billions of BITS, by years since launch. Hover or use the arrow keys for each year.
| Since launch | Reward / block | New / year | Total | Of final |
|---|---|---|---|---|
| Year 1 | 1,000 | 2.10B | 2.17B | 10% |
| Year 5 | 1,000 | 2.10B | 10.58B | 50% |
| Year 10 | 500 | 1.05B | 15.84B | 75% |
| Year 15 | 250 | 0.53B | 18.46B | 88% |
| Year 20 | 125 | 0.26B | 19.78B | 94% |
| Long run | → 0 | → 0 | ≈ 21.09B | 100% |
03 · Inflation
High early. Falls fast.
We'd rather you hear it from us: because supply starts small, new coins grow it quickly in the first years. Each halving cuts the rate, and by year 11 it's down to about 3% a year.
Yearly supply growth
New BITS minted that year as a share of the supply at the start of it. Year 1 is left out because supply grows from the 67.5M launch allocation alone.
Halvings at the start of years 6, 11 and 16 each cut the rate roughly in half.
- ~97%Year 2: supply roughly doubles.
- ~25%Year 5: the last year at 1,000 BITS per block.
- ~10%Year 6: right after the first halving.
- ~3%Year 11: after the second halving.
04 · Launch allocation
Big at launch. Tiny in the end.
Block 1 created a one-time allocation of 67,500,000 BITS, mined into the miner wallet of the network's first node. It dominates supply at first, then shrinks as mining adds new coins.

The allocation plan
How the launch allocation is split, whether it's locked or vested, and what it will be used for will be published here.
05 · Holder protections
Rules every node enforces.
These aren't promises. They're written into the code, and every node on the network checks them.
Mined coins wait
New coins can't be spent for 100 blocks (about 25 minutes). Blocks mined before block 500 used a shorter 8-block lock.
Fees go to miners
Transaction fees are paid to the miner who includes them, and take over as the main reward as halvings shrink new coins.
Solo miners keep it all
URPool takes 0.5% for development and 2% for the health fund from what it mines. Mine solo and you keep everything.
06 · FAQ
Good questions.
Why does the code say 21 billion if the cap is 21.09 billion?
The MAX_MONEY constant (21 billion) is not the supply cap. It only limits the size of a single amount or transaction. The real cap comes from the halving schedule, which adds up to about 21.09 billion BITS. No rule checks total supply against MAX_MONEY.
Can I check the supply myself?
Yes. The block explorer shows the live supply. For example, at block 410 it showed 67,909,000 BITS: 67.5M from block 1 plus 409 blocks of 1,000. That's exactly what the rules predict.
How many BITS are created each day?
5,760 blocks a day × 1,000 BITS = 5,760,000 BITS a day until the first halving, then 2,880,000 a day, and so on.
What happens when block rewards end?
After 64 halvings no new coins are created. Miners keep securing the network in exchange for transaction fees, the same model Bitcoin moves toward.
Why is inflation so high in the first years?
Because the chain is new, the existing supply is small compared with the 2.1 billion BITS mined each year at first. The rate drops quickly as supply grows and each halving cuts new issuance in half.
