Core Architecture

B² Network is designed as a modular Bitcoin + AI settlement infrastructure, enabling the vision of “Put Bitcoin in Every AI’s Wallet.”

The architecture is built around five tightly connected modules, each solving a key challenge in unifying Bitcoin, AI Agents, and Stablecoin economies:

  1. Mining² (DeFAI-Mining Router) Connects Bitcoin miners to the network by routing hashrate and BTC revenues into staking pools, agent wallets, and validator incentives. It bridges Proof-of-Work security with Proof-of-Signal governance.

  2. B² Hub (Layer 1.5 PoSg Consensus) A sovereign “Layer 1.5” chain powered by Proof-of-Signal + Stake (PoSg).

    • Signals from AI agents and delegators determine validator voting power.

    • Application sharding separates Signal, Agent, and Stablecoin execution environments.

    • Anchors finality to Bitcoin via Taproot inscriptions for global security.

  3. B² Rollup (BTC-Anchored L2 Execution Layer) An EVM-compatible rollup environment with high throughput and native BTC-denominated gas.

    • Aggregates transactions, zk/fraud proofs, and data commitments.

    • Posts merkle roots and proofs to Bitcoin for trustless anchoring.

    • Enables developers to deploy dApps and smart contracts with BTC settlement.

  4. DSN-AI (Signal-Driven Agentic AI Layer) The protocol layer that integrates autonomous AI agents directly into blockchain consensus.

    • Agents emit verifiable “signals” representing perception, planning, and actions.

    • Validators use signals to adjust voting power via SignalScore.

    • Provides Agent-Native Abstraction Accounts (A-AA), enabling agents to hold and transact in BTC or U2 natively.

  5. U2 Stablecoin (BTC-Collateralized Settlement Layer) A Bitcoin-backed stablecoin designed for micro-payments and predictable pricing.

    • Over-collateralized by BTC with hedging strategies for peg stability.

    • Used by agents for task payments, settlements, and long-term contracts.

    • Serves as the stable economic medium for the AI-driven ecosystem.

Architectural Flow

  • From Mining to AI: BTC mined by Mining² flows into validators and agents, securing the Hub.

  • From Agents to Consensus: AI signals are aggregated into the Hub’s PoSg consensus, shaping governance and execution.

  • From Rollup to Bitcoin: Transactions and proofs are rolled up and anchored to Bitcoin for ultimate settlement finality.

  • From BTC to Stability: U2 stablecoin ensures agents and users transact with predictable value.

Together, these modules form a closed economic and technical loop: BTC → Signals → Consensus → Rollup Execution → U2 Stablecoin → AI Economy → back to BTC.

This architecture transforms Bitcoin from a passive store of value into the active settlement currency of the AI era.
