1. Abstract
The Nexus AI Chain introduces a paradigm shift in blockchain consensus by replacing energy-intensive
Proof-of-Work (PoW) and capital-intensive Proof-of-Stake (PoS) with Proof-of-AI (PoAI). In this
model, validators perform useful machine learning computations—such as training LLMs or folding
proteins—to validate blocks. The AIXN coin serves as the economic fuel for this compute-centric economy,
aligning the incentives of miners (AI Nodes), developers, and users.
2. Tokenomics & Emission
AIXN operates on a deflationary emission schedule. Unlike traditional models where inflation is
perpetual, AIXN burns a portion of every transaction fee (`BaseFee`) while tipping the remainder to AI
Nodes (`PriorityFee`).
Total_Supply(t) = Initial_Supply - ∫ Burn_Rate(t) dt
► Initial Supply: 145,000,000 AIXN
► Utility: Gas for execution, Collateral for
Validator Nodes, Weights for Governance
► Halving: Every 2.4 Years (based on Compute Moore's
Law)
3. Proof-of-AI Consensus
Validators are ranked by their "Compute Reputation Score" (CRS). A node's probability of proposing a
block is proportional to its contribution to the global AI workload.
struct Validator {
address: Address,
stake: u64,
compute_power: Float64, // TFLOPS
reputation: u32, // 0-100
}
fn select_proposer(validators: Vec) -> Address {
// Weighted random selection based on (Stake * Reputation^2)
...
}
This ensures that the network is secured not just by capital, but by intelligence.
4. Native Coin Migration
The transition from ERC-20 to Native Coin enabled atomic swaps and Layer-1 optimisations. The legacy
`AINX.sol` contract has been deprecated. All account states were migrated via a genesis snapshot at
Block #12,000,000.
