Mandatory Upgrade

Overview

Genome-PoW Combines

A multi-layered evolutionary consensus mechanism that unifies cryptographic security with biological complexity.

Final PoW Formula

final_hash = blake3(genome_i ‖ header_hash ‖ nonce)

Block valid when: final_hash < target

Fragment-Based Entropy

~3 billion genome bases across 22 chromosomes + X and Y, packed in 2-bit encoding into a ~750 MB memory-hard dataset.

Deterministic Mutations

Genome fragments undergo K(epoch) ∈ [4,16] mutation rounds — Swap, Insert, Rotate, XOR, Shift — all fully deterministic.

Fitness Scoring

Lightweight scoring via Shannon entropy, GC content balance, and pattern detection produces a fitness_value: u32 per block.

Adaptive Epoch Updates

Every 200 blocks, epoch_score = median fitness updates mutation rounds, weighting, and the next genome seed via BLAKE3.

Reward Multiplier

Miners are rewarded for optimization: multiplier = clamp(1 + (fitness/threshold)², 1, 2) on top of base_reward.

Memory-Hard Design

The ~750 MB genome dataset requirement makes parallel ASIC attacks economically unfeasible and impractical.

Genome-PoW

The Genome Dataset

The entire human genome becomes your mining dataset — deterministically selected, mutated, and scored.

Fragment Selection

// Deterministic fragment selection
index_hash = blake3(epoch_seed ‖ nonce)
fragment_index = rejection_sample(index_hash)
% num_fragments

Block Genome Generation

genome_0 = selected_fragment
for i in 0..K(epoch) {
apply_deterministic_mutation();
}
// K(epoch) ∈ [4, 16]

Fitness Scoring

Lightweight Fitness Score

Keeps validation fast while incentivizing miners to produce high-quality genome mutations.

Shannon Entropy

Measures randomness and information content across the mutated genome fragment.

w1

GC Content Balance

Evaluates the ratio of guanine-cytosine pairs — a biological stability indicator.

w2

Pattern / Cycle Detection

Penalizes repetitive or degenerate patterns that reduce biological diversity.

w3

Fitness Type

fitness_value: u32

A single 32-bit unsigned integer representing the overall fitness of the mutated genome fragment. Lightweight enough for fast consensus verification.

Example Fitness Model

// Weighted combination
fitness = w1 * entropy
+ w2 * gc_score

Weights w1 and w2 are adjusted adaptively per epoch, ensuring the network evolves its scoring over time.

Why Fitness Matters

  • Incentivizes high-quality mutation strategies
  • Prevents degenerate or trivial mining shortcuts
  • Drives continuous evolutionary improvement
  • Validated deterministically in O(n) time
Epoch System

Continuous Evolution

Every 200 blocks, the network updates its genome seed and mutation parameters — evolving deterministically while remaining fully verifiable.

Epoch Parameters

Epoch Length200 blocks
Epoch Score
median(fitness of last
200 SP-chain blocks)
Next Seed
blake3(epoch_score ‖
prev_epoch_seed)

Epoch Flow

Mine 200 blocks
Collect fitness scores from SP-chain
Compute median
epoch_score = median(fitness[])
Derive new seed
blake3(epoch_score ‖ prev_seed)
Update parameters
Rounds, weights, memory, fitness
Next epoch begins
Network evolves forward

What Updates Per Epoch

1
Mutation Rounds
K(epoch) adjusts between 4–16
2
Mutation Weighting
Relative probability of each mutation type
3
Memory Weight
Dataset access patterns and caching strategy
4
Fitness Weighting
w1, w2 coefficients for scoring

The network evolves continuously while remaining fully deterministic — any node can independently verify and reproduce every epoch transition.

Security Model

Built for Adversarial Environments

Genome-PoW layers biological complexity on top of cryptographic primitives — delivering robust, adaptive security that scales with the network.

Memory Hardness

~750 MB

The full genome dataset must be held in memory during mining, preventing lightweight ASIC implementations.

ASIC Resistance

Adaptive

Evolving mutation parameters and epoch-driven seed rotation make custom silicon optimization impractical.

Deterministic Verification

O(n)

Any node can independently verify a block in bounded linear time — no additional trust assumptions required.

Adaptive Complexity

Per Epoch

Mutation rounds and weighting shift every 200 blocks, continuously raising the bar for optimization attacks.

🔬Fitness-Based Incentive

By rewarding miners for producing high-fitness genome mutations, the network creates an economic incentive that naturally resists lazy or degenerate mining strategies.

  • Lazy miners earn lower rewards
  • High-fitness mining requires genuine computation
  • Fitness threshold adapts with the epoch
  • No shortcut to high fitness without memory access

Reward Mechanism

Fitness-Driven Rewards

Better mutations earn better rewards. Aligned incentives while preserving predictable issuance bounds.

Reward Multiplier Formula

multiplier = clamp(
1 + (fitness / threshold)²,
min: 1,
max: 2
)
reward = base_reward * multiplier
1.0×Min MultiplierNo fitness boost
2.0×Max MultiplierOptimal fitness
≤2×Issuance BoundFully predictable

Fitness → Multiplier Curve

fitness = 0fitness = threshold
1.0× reward2.0× reward

Distribution

Miner Reward
90%

First coinbase output — goes directly to mining address

Network Fund
10%

Second coinbase output — sustains network development

Incentive Alignment

  • Miners rewarded for quality, not just speed
  • Predictable issuance — bounded by 2× cap
  • No inflation surprises for token holders
  • Network fund is permissionless and transparent
