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:
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.
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.
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.
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.
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.
