B² Network is a next-generation Layer2 scaling solution built on top of Bitcoin (BTC), aiming to significantly enhance Bitcoin’s performance and scalability without compromising its foundational security. By integrating zero-knowledge proofs (ZKP) and adopting a modular blockchain architecture, B² Network not only alleviates Bitcoin’s congestion issues but also expands its programmability and utility in the broader crypto ecosystem.

At the core of B² Network’s architecture are four major innovations:

1. B² Rollup — Bitcoin Layer2 Execution Layer: B² Rollup introduces a Bitcoin-native Layer2 solution that leverages zero-knowledge proof verification commitments. It enables users and developers to execute smart contracts and batch transactions off-chain with cryptographic proofs of correctness. These proofs are periodically committed to the Bitcoin mainnet, preserving Bitcoin’s unparalleled security while massively boosting throughput and reducing transaction costs. Thanks to its EVM-compatibility, B² Rollup makes it easy for existing Ethereum developers to migrate or expand their applications into the Bitcoin ecosystem.
   
   
2. B² Hub — Bitcoin Layer1.5 Data Availability Layer: Acting as Bitcoin’s Data Availability (DA) layer, B² Hub ensures that all transaction data and rollup proofs are permanently stored and finalized on the Bitcoin blockchain. This “Layer1.5” approach tightly couples Layer2 operations with Bitcoin’s final settlement layer, achieving both high scalability and robust data persistence.
   
   
3. B² Buzz — BTC-Fi Yield Product: B² Buzz is B² Network’s innovative BTC-Fi platform designed to unlock additional yield opportunities for BTC holders. It offers various financial strategies such as staking, liquidity mining, and structured products, allowing users to earn passive income while still maintaining exposure to Bitcoin.
   
   
4. MiningSquared — Bitcoin Mining Yield Enhancement: MiningSquared is B² Network’s mining pool solution that integrates traditional Bitcoin mining with DeFi-like yield opportunities. It offers auto-subscribable BTC yield products tailored for miners and BTC holders. Participants can allocate mined BTC directly into B² Buzz strategies or other financial products, optimizing capital efficiency and diversifying income streams beyond just block rewards.
   

Together, these four components create a comprehensive Layer2 ecosystem that not only scales Bitcoin’s technical capabilities but also unlocks new financial applications and opportunities around BTC.

By blending modular design, zero-knowledge proof technology, and a focus on Bitcoin-native financial products, B² Network envisions a future where Bitcoin is not just a store of value, but also the foundation of a dynamic, high-performance financial ecosystem.
