Allocation Breakdown
| Category | Percentage | Tokens | Vesting |
|---|---|---|---|
| Block Rewards | 70% | 700,000,000 | Halving schedule (see below) |
| Ecosystem & Grants | 10% | 100,000,000 | 5-year linear from TGE |
| Foundation Reserve | 10% | 100,000,000 | 1-year cliff + 4-year linear |

Block Rewards (70%)
The largest allocation ensures long-term validator incentives and network security. Tokens are minted on every block according to the halving schedule—none are pre-minted. Distribution is proportional to validator stake.
Ecosystem & Grants (10%)
Developer grants, DApp incentives, hackathons, bridge integrations, and strategic partnerships. Controlled by governance with 5-year linear vesting.
Foundation Reserve (10%)
Protocol development, security audits, infrastructure, legal, and operations. 1-year cliff followed by 4-year linear vesting.
Team & Core Contributors (5%)
4-year vesting: 1-year cliff, then monthly linear unlock over 3 years.
Sales (5%)
Private and public sale allocation. 6-month cliff + 18-month linear vesting.
Emission Schedule
Parameters
| Parameter | Value |
|---|---|
| Block Rewards Pool | 700,000,000 PRIM |
| Initial Reward per Block | 10 PRIM |
| Halving Interval | 35,000,000 blocks |
| Block Time | ~1 second |
| Halving Period | ~2.22 years |
Halving Epochs
Rewards follow a Bitcoin-style halving schedule:
| Era | Block Range | Reward/Block | Minted in Era |
|---|---|---|---|
| 0 | 0 — 34,999,999 | 10 PRIM | 350,000,000 |
| 1 | 35,000,000 — 69,999,999 | 5 PRIM | 175,000,000 |
| 2 | 70,000,000 — 104,999,999 | 2.5 PRIM | 87,500,000 |
| 3 | 105,000,000 — 139,999,999 | 1.25 PRIM | 43,750,000 |
| 4 | 140,000,000 — 174,999,999 | 0.625 PRIM | 21,875,000 |
| 5 | 175,000,000 — 209,999,999 | 0.3125 PRIM | 10,937,500 |
| 6 | 210,000,000 — 244,999,999 | 0.15625 PRIM | 5,468,750 |
| ... | (continues halving) | ... | ... |
The geometric series converges to exactly 700,000,000 PRIM:
total = initial_reward × halving_interval × 2
= 10 × 35,000,000 × 2
= 700,000,000 PRIM ✓
Emission Timeline
| Milestone | Era | Approx. Time | Block Rewards Minted | % of Pool |
|---|---|---|---|---|
| First halving | 1 | ~2.2 years | 350,000,000 | 50.0% |
| Second halving | 2 | ~4.4 years | 525,000,000 | 75.0% |
| 87.5% minted | 3 | ~6.7 years | 612,500,000 | 87.5% |
| 93.75% minted | 4 | ~8.9 years | 656,250,000 | 93.75% |
| 96.9% minted | 5 | ~11.1 years | 678,125,000 | 96.9% |
| 99%+ minted | 6 | ~13 years | 689,062,500 | 98.4% |
99% of block rewards are emitted by approximately year 13.
Reward Distribution
Block rewards are distributed to all active validators proportionally to their stake:
validator_reward = (effective_reward × validator_stake) / total_stake
Example: Equal Stake
With 4 validators each staking 1,000,000 PRIM:
- Total stake = 4,000,000 PRIM
- Block reward = 10 PRIM
- Each validator = 10 × (1,000,000 / 4,000,000) = 2.5 PRIM per block
Example: Unequal Stake
| Validator | Stake | Share | Reward/Block |
|---|---|---|---|
| A | 5,000,000 | 50% | 5.0 PRIM |
| B | 3,000,000 | 30% | 3.0 PRIM |
| C | 1,500,000 | 15% | 1.5 PRIM |
| D | 500,000 | 5% | 0.5 PRIM |
| Total | 10,000,000 | 100% | 10.0 PRIM |
Supply Cap Enforcement
Before distributing any reward, the system checks:
remaining_supply = max_supply - total_minted
effective_reward = min(scheduled_reward, remaining_supply)
Individual validator rewards are calculated from effective_reward. This ensures total_minted never exceeds 1,000,000,000 PRIM.
Rounding and Burns
Due to integer division with 18-decimal precision, the sum of individual rewards may be slightly less than the effective reward. The difference is implicitly burned—typically negligible (0–2 wei per block) but enforces the supply cap.
