In building a truly decentralized and sustainably secure blockchain network, monetary policy transparency and predictability form the bedrock of user trust. Users choose a chain not only for its performance and features, but fundamentally for their confidence in its economic rules.
To this end, our block reward mechanism strictly adheres to a hard supply cap, implementing a time-tested Bitcoin-style halving model, reinforced by rigorous engineering safeguards to ensure protocol integrity under all conditions—even in edge cases.
Hard Supply Cap: 21 Million Tokens, No Exceptions
Our network enforces a definitive maximum supply of 21,000,000 tokens (including any genesis allocation). To achieve this, block rewards follow a classic exponential decay schedule:
- Initial block reward:50 Ebro
- Reward halves every 210,000 blocks (approximately every 4 years)
- Rewards are calculated in integer units (with the smallest unit being 1 wei) and rounded down
- When the reward falls below 1 wei, it automatically drops to zero
This ensures miner rewards gradually diminish over time and eventually cease entirely. Beyond that point, network security will be sustained solely through transaction fees—an approach philosophically aligned with Bitcoin’s long-term vision.
✅ Result: Total supply converges precisely to 21 million tokens—zero inflation, guaranteed.
Engineering Safeguards: Protocol-Level Robustness
To guarantee reliability even under extreme conditions, we’ve embedded multiple code-level safety mechanisms into the reward calculation logic:
- Overflow protection: If the halving count reaches ≥64 (far beyond the point where rewards naturally hit zero), the function returns 0 immediately—avoiding unnecessary or undefined computations.
- Parameter validation: Critical constants like initial reward and halving interval undergo strict sanity checks to prevent misconfiguration from disrupting consensus.
- Sub-wei truncation: Rewards below 1 wei are forced to zero, eliminating risks from floating-point imprecision or storage inefficiencies.
These measures do not alter the economic model—they only enhance system robustness, ensuring all nodes reach consensus reliably, even at astronomically high block heights or under anomalous inputs.
Why We Reject a “Minimum Reward”
Some projects maintain miner incentives by enforcing a non-zero “floor” reward (e.g., 0.001 tokens per block). However, this approach leads to:
- Unbounded token supply, violating the principle of digital scarcity;
- Perpetual inflation, eroding long-term holder value;
- Ambiguous monetary policy, undermining user trust in the protocol’s credibility.
We firmly believe: True security must not rely on perpetual issuance, but on clear, verifiable, and finite rules. Therefore, we commit to a clean “halve-to-zero” path—entrusting the future to the market, where users organically incentivize validators through transaction fees.
A Sustainable Future
This design not only inherits Bitcoin’s core value proposition—predictable scarcity—but also demonstrates through engineering rigor that a decentralized network can achieve long-term sustainability without compromising security, transparency, or supply discipline.
21 million tokens. Not one more, not one less.
This is our promise—and our understanding of digital value.
