Halving Schedule

Introduction

Fenine Network implements a halving schedule that systematically reduces block rewards over time. This mechanism ensures long-term sustainability by controlling inflation while maintaining security incentives for validators.

Key Points:

Initial Block Reward: 3.5 FEN per block
Halving Interval: Every 10,512,000 blocks (~1 year)
First Halving: Block 10,512,000 (Q1 2026)
Final Reward: 0.109375 FEN per block (after 5 halvings)

Halving Mechanism

How It Works

Every 10,512,000 blocks (~365 days), the block reward is reduced by 50%. Formula:

R_n = R_0 \\times \\left(\\frac{1}{2}\\right)^n

Where:

$R_n$ : Block reward after $n$ halvings
$R_0$ : Initial block reward (3.5 FEN)
$n$ : Number of halvings

Block Time Calculation

With 3-second block times:

\\text{Blocks per year} = \\frac{365.25 \\times 24 \\times 60 \\times 60}{3} = 10,512,000 \\text{ blocks}

Halving Timeline

Schedule Overview
Year by Year
Cumulative Supply

Halving	Block Height	Date (Est.)	Block Reward	Annual Emission	% of Initial
Genesis	0	2025-01-01	3.5 FEN	36,792,000 FEN	100%
1st	10,512,000	2026-01-01	1.75 FEN	18,396,000 FEN	50%
2nd	21,024,000	2027-01-01	0.875 FEN	9,198,000 FEN	25%
3rd	31,536,000	2028-01-01	0.4375 FEN	4,599,000 FEN	12.5%
4th	42,048,000	2029-01-01	0.21875 FEN	2,299,500 FEN	6.25%
5th	52,560,000	2030-01-01	0.109375 FEN	1,149,750 FEN	3.125%
6th+	63,072,000+	2031+	<0.11 FEN	Decreasing	<3%

After 5 halvings, block rewards become negligible. Validators increasingly rely on transaction fees for revenue.

Total FEN minted through block rewards:

Year	Cumulative Emission	% of Max Supply
2025	36,792,000	36.79%
2026	55,188,000	55.19%
2027	64,386,000	64.39%
2028	68,985,000	68.99%
2029	71,284,500	71.28%
2030	72,434,250	72.43%
2035	~73,500,000	~73.5%
2050	~73,580,000	~73.58%

Maximum Theoretical Supply (infinite halvings):

S_{\\text{max}} = R_0 \\times B_{\\text{year}} \\times \\sum_{n=0}^{\\infty} \\left(\\frac{1}{2}\\right)^n = 3.5 \\times 10,512,000 \\times 2 = 73,584,000 \\text{ FEN}

This is 73.58% of the 100M max supply cap.

Deflationary by Year 4: With moderate network activity, Fenine becomes deflationary after 2028.

Rapid growth initially, then flattening towards asymptotic limit.

Validator Economics

How halvings affect validator profitability: Year 1 (2025): High Rewards Era

Block reward: 3.5 FEN
Validator with 1% stake: ~367,920 FEN/year
APY: Very High (early adopter advantage)

Year 2 (2026): First Halving

Block reward: 1.75 FEN (50% reduction)
Same validator: ~183,960 FEN/year
APY: Still High (50% of previous)
Mitigation: Network growth, more transaction fees

Year 3-4 (2027-2028): Transition Period

Block rewards continue decreasing
Transaction fees become significant
Validators optimize for fee capture
APY: Moderate but sustainable

Year 5+ (2029+): Fee-Dominant Era

Block rewards minimal
80%+ revenue from transaction fees
High-activity validators earn more
APY: Competitive with traditional finance

Fee Market Evolution

As block rewards decrease, transaction fees become primary validator revenue:

Year	Block Reward Revenue	Fee Revenue (est.)	Fee % of Total
2025	95%	5%	5%
2026	90%	10%	10%
2027	80%	20%	20%
2028	65%	35%	35%
2029	45%	55%	55%
2030	30%	70%	70%
2035	<10%	>90%	>90%

Implication: Validators increasingly compete for transaction throughput and fee optimization.

Impact on Staking APY

APY Projections

Estimated staking APY over time (assumes stable network stake):

Conservative
Moderate
Optimistic

Low network activity, minimal fee revenue:

Year	Block Rewards	Fees	Total APY
2025	36.8%	0.5%	37.3%
2026	18.4%	1.0%	19.4%
2027	9.2%	1.5%	10.7%
2028	4.6%	2.0%	6.6%
2029	2.3%	2.5%	4.8%
2030	1.15%	3.0%	4.15%

Still competitive with traditional staking platforms.

Medium network activity, growing fee market:

Year	Block Rewards	Fees	Total APY
2025	36.8%	1.0%	37.8%
2026	18.4%	2.5%	20.9%
2027	9.2%	4.0%	13.2%
2028	4.6%	6.0%	10.6%
2029	2.3%	8.0%	10.3%
2030	1.15%	10.0%	11.15%

Sustainable double-digit APY through fee growth.

High network activity, vibrant DeFi ecosystem:

Year	Block Rewards	Fees	Total APY
2025	36.8%	2.0%	38.8%
2026	18.4%	5.0%	23.4%
2027	9.2%	8.0%	17.2%
2028	4.6%	12.0%	16.6%
2029	2.3%	15.0%	17.3%
2030	1.15%	18.0%	19.15%

APY remains high as fee revenue offsets reward reduction.

Smart Contract Implementation

Halving Logic

The halving is implemented in the FenineSystem contract:

function getBlockReward(uint256 blockNumber) public pure returns (uint256) {
    uint256 HALVING_INTERVAL = 10_512_000;
    uint256 INITIAL_REWARD = 3.5 ether;
    
    // Calculate number of halvings
    uint256 halvings = blockNumber / HALVING_INTERVAL;
    
    // Max 10 halvings (after that, reward is negligible)
    if (halvings >= 10) {
        return 0;
    }
    
    // Calculate reward: initial_reward / (2^halvings)
    return INITIAL_REWARD >> halvings;  // Bit shift = divide by 2
}

Query Current Reward

// Using ethers.js
const fenineSystem = new ethers.Contract(
  "0x0000000000000000000000000000000000001000",
  FENINE_SYSTEM_ABI,
  provider
);

// Get current block number
const blockNumber = await provider.getBlockNumber();

// Get current block reward
const reward = await fenineSystem.getBlockReward(blockNumber);

console.log("Current block:", blockNumber);
console.log("Block reward:", ethers.formatEther(reward), "FEN");

// Calculate halvings occurred
const halvings = Math.floor(blockNumber / 10512000);
console.log("Halvings:", halvings);

Check Next Halving

const HALVING_INTERVAL = 10_512_000;

const currentBlock = await provider.getBlockNumber();
const currentHalving = Math.floor(currentBlock / HALVING_INTERVAL);
const nextHalvingBlock = (currentHalving + 1) * HALVING_INTERVAL;
const blocksUntilHalving = nextHalvingBlock - currentBlock;

// Convert to time (3 second blocks)
const secondsUntilHalving = blocksUntilHalving * 3;
const daysUntilHalving = secondsUntilHalving / 86400;

console.log("Next halving at block:", nextHalvingBlock);
console.log("Blocks remaining:", blocksUntilHalving);
console.log("Days until halving:", daysUntilHalving.toFixed(2));

Comparison with Other Networks

Network	Halving Interval	Initial Reward	Current Reward	Total Supply Cap
Fenine	1 year	3.5 FEN	3.5 FEN	100M
Bitcoin	4 years	50 BTC	6.25 BTC	21M
Litecoin	4 years	50 LTC	12.5 LTC	84M
Bitcoin Cash	4 years	50 BCH	6.25 BCH	21M
Dash	~383 days	50 DASH	~2.7 DASH	18.9M

Fenine’s Approach:

Faster halvings (1 year vs 4 years) = quicker scarcity
Higher initial inflation = network bootstrap and growth
Earlier deflation = sustainable long-term tokenomics

Frequently Asked Questions

Will APY drop to zero after halvings?

No. Transaction fees replace block rewards as primary validator revenue.With moderate network activity, APY remains at 8-15% even after 5 halvings (2030+).High-activity networks can sustain even higher APY from fees alone.

Should I stake now or wait?

Stake now. Early stakers benefit from:

Highest block rewards (3.5 FEN/block)
Compounding at maximum APY
Lower network competition
Earlier entry into proximity network

Every year, rewards halve. Waiting means missing out.

What happens to validators after 10 halvings?

After 10 halvings, block rewards become negligible (<0.01 FEN).Validators survive on:

Transaction fees (primary revenue)
MEV (if applicable)
Commission from delegators
