# AITBC Full Documentation

Complete technical documentation for the AI Training & Blockchain Computing platform

# Introduction

AITBC (AI Training & Blockchain Computing) is a decentralized platform that combines artificial intelligence and blockchain technology to create a trustless marketplace for AI/ML workloads. The platform enables secure, private, and verifiable computation while maintaining transparency through blockchain technology.

## Key Features

- Decentralized Marketplace: Connect AI service providers with consumers in a trustless environment
- Confidential Computing: Zero-knowledge proofs and secure enclaves protect sensitive data
- High Performance: Sharding and rollups achieve 100,000+ TPS with sub-second finality
- Privacy-Preserving: Advanced cryptography ensures data confidentiality
- Token Economics: Sustainable incentives for all participants
- Autonomous Agents: AI agents can participate as marketplace providers

## Use Cases

#### Healthcare AI

Secure medical image analysis, drug discovery, and patient data processing while maintaining HIPAA compliance through confidential computing.

#### Financial Services

Fraud detection, risk assessment, and algorithmic trading with verifiable computation and audit trails.

#### Scientific Research

Collaborative research with data privacy, reproducible results, and fair attribution through blockchain verification.

# Architecture

## Core Components

graph TB A[Client] --> B[Coordinator API] B --> C[Blockchain Node] B --> D[GPU Providers] C --> E[Consensus Engine] C --> F[Smart Contracts] D --> G[ZK Proofs] F --> H[Receipt Storage]

### Blockchain Node

The blockchain node implements a hybrid Proof of Authority/Proof of Stake consensus mechanism with three operational modes:

- FAST Mode: 100-200ms finality, up to 50,000 TPS
- BALANCED Mode: 500ms-1s finality, up to 20,000 TPS
- SECURE Mode: 2-5s finality, up to 10,000 TPS

### Coordinator API

The coordinator serves as the central hub for marketplace operations:

- Job scheduling and management
- Receipt verification and storage
- Provider registration and reputation tracking
- Multi-tenant support with isolation
- Real-time metrics and analytics

### GPU Service Provider

Decentralized compute providers offer various AI/ML services:

- Model inference (text, image, audio, video)
- Model training and fine-tuning
- Data preprocessing and augmentation
- Result verification with ZK proofs
- Cross-chain compatibility

## Consensus Mechanism

The hybrid consensus combines the speed of Proof of Authority with the decentralization of Proof of Stake:

### Mode Selection Algorithm

    def determine_mode(network_metrics):
        load = network_metrics.utilization
        auth_availability = network_metrics.authority_uptime
        stake_participation = network_metrics.stake_ratio

        if load < 0.3 and auth_availability > 0.9:
            return ConsensusMode.FAST
        elif load > 0.7 or stake_participation > 0.8:
            return ConsensusMode.SECURE
        else:
            return ConsensusMode.BALANCED

### Validator Selection

#### Authority-Only Selection

- VRF-based random selection from 21 authorities
- 100ms block time
- 2/3 signature threshold

#### Hybrid Selection

- 70% authority, 30% staker selection
- 500ms block time
- 2/3 authority + 1/3 stake threshold

#### Stake-Weighted Selection

- Full stake-weighted selection
- 2s block time
- 2/3 stake threshold
