AITBC v0.2.0 Release Notes

Date: February 1, 2026
Status: ✅ Released
Scope: Enhanced services and trading infrastructure

🎯 Overview

AITBC v0.2.0 is a major infrastructure enhancement release that introduces wallet daemon, trade exchange with Bitcoin integration, and Zero-Knowledge proof capabilities. This release establishes the foundation for secure transactions and privacy-preserving features.

🚀 New Features

💰 Wallet Daemon

  • FastAPI Service: REST and JSON-RPC endpoints for wallet management
  • Encrypted Keystore: Argon2id + XChaCha20-Poly1305 encryption
  • Mock Ledger Adapter: SQLite backend for testing
  • Port Configuration: Running on port 8002, nginx proxy at /wallet/
  • Bitcoin Payment Gateway: Bitcoin payment integration for AITBC purchases
  • Dependencies: aitbc-sdk, aitbc-crypto, fastapi, uvicorn

🏪 Trade Exchange

  • User Management System: Individual wallet management per user
  • Bitcoin Integration: QR code generation for Bitcoin payments
  • Real-time Payment Monitoring: Live payment status tracking
  • Session-based Authentication: Secure user authentication
  • Exchange Rate: 1 BTC = 100,000 AITBC
  • Deployment: https://aitbc.bubuit.net/Exchange/

🔐 Zero-Knowledge Applications

  • Circom Compiler v2.2.3: ZK circuit compilation capability
  • ZK Circuits Compiled: receipt_simple with 300 constraints
  • Trusted Setup Ceremony: Powers of Tau setup completed
  • Privacy Features:
    • Identity commitments
    • Stealth addresses
    • Private receipt attestation
    • Group membership proofs
    • Private bidding
    • Computation proofs
  • API Endpoints: /api/zk/ for ZK operations
