What is BSquared Network (B2)?

Deep Dive

1. Purpose & Evolution

BSquared Network's core mission is to unlock Bitcoin's potential beyond a store of value. Initially launched as an EVM-compatible Bitcoin Layer 2 (L2) to solve congestion and scalability, the project has pivoted toward a broader vision. As of November 2025, the team described B² as "Bitcoin-based AI payment infrastructure" (B² Network). The goal is to establish Bitcoin as a secure, global settlement layer for the emerging AI economy, enabling AI agents to transact and communicate value on-chain.

2. Technology & Architecture

The network employs a modular architecture anchored to Bitcoin's security:

• B² Rollup: A zero-knowledge (ZK) rollup that is compatible with the Ethereum Virtual Machine (EVM), allowing developers to deploy smart contracts for fast, low-cost transactions.
• B² Hub: Acts as a "Layer 1.5" data availability layer. It uses a novel consensus called Proof of Signal (PoSg), which incorporates AI to verify and anchor data to the Bitcoin mainnet, achieving finality with sub-200ms latency (B² Network).
• Mining²: A Bitcoin mining pool that integrates with DeFi, allowing miners to automatically compound earnings into yield-generating strategies.

3. Ecosystem & Use Cases

The ecosystem is designed to make Bitcoin productive and usable. Key products include:

• Buzz: A portal for BTC holders to access curated yield strategies across multiple chains like Solana and BNB Chain.
• U2 Stablecoin: A USD-pegged stablecoin backed by Bitcoin, launched in September 2025, designed for high-frequency payments, particularly for AI agents.
• AI Signal Protocol: A framework that allows AI agents to send verifiable on-chain signals for tasks, payments, and collaboration, forming the basis for AI-to-AI commerce.

Conclusion

BSquared Network is fundamentally a project transforming Bitcoin from a passive asset into an active, intelligent economic substrate for both humans and machines. How effectively will its AI-native architecture attract developers and agents to build on Bitcoin?
