Smart Contract Overview

Hokusai's smart contract system is modular, designed to support decentralized AI model development and tokenization. Here's a simplified flow:

[Data Contributor]
    ↓ submits data
[DeltaOneVerifier] → validates performance improvement
    ↓ confirms DeltaOne
[TokenManager] → mints model tokens
    ↓ distributes rewards
[Token Holders]
    ↓
[HokusaiAMM] ← buy/sell with USDC (CRR bonding curve)
    ↓
[API Usage] → fees deposited to AMM reserve → price increases
    ↓
[ModelAccessController] → enforces burn for usage

Key Components​

Core Contracts​

  • HokusaiToken (ERC20): Model-specific token, earned via performance gains
  • TokenManager: Issues tokens, handles mint/burn logic, distributes rewards
  • DeltaOneVerifier: Validates performance improvements off-chain, triggers minting
  • ModelRegistry: Maps model IDs to token addresses

AMM & Trading​

  • HokusaiAMM: CRR bonding curve for buying/selling tokens with USDC
  • HokusaiAMMFactory: Deploys new AMM pools for each model
  • UsageFeeRouter: Routes API fees to AMM reserves (20%) and infrastructure (80%)

Access Control​

  • ModelAccessController: Enforces token burning for model usage
  • Governance: Token holder voting on parameters

Key Features​

Seven-Day Launch Period​

  • Each model token starts with buy-only period (Days 0-6)
  • Full trading enabled after Day 7
  • Prevents manipulation and enables fair price discovery

API Fee Integration​

  • 20% of API fees flow to AMM USDC reserves
  • Increases reserve without minting tokens
  • Raises spot price: P = R / (w × S)
  • Creates value for token holders from model usage
