B² Network
The Most Practical Bitcoin Layer-2 Network.

About
B² Network is a modular Bitcoin Layer-2 solution designed to enhance transaction speed, reduce costs, and expand application diversity without compromising security. As the first zero-knowledge proof (zk-proof) verification commitment rollup on Bitcoin, B² Network enables Turing-complete smart contracts for off-chain transactions, paving the way for decentralized finance (DeFi), non-fungible tokens (NFTs), and other decentralized applications (dApps) within the Bitcoin ecosystem.
Key Features
-
Zero-Knowledge Rollup (ZK-Rollup)
B² Network employs zk-proof technology to bundle multiple transactions into a single proof, enhancing transaction efficiency and minimizing costs—while ensuring privacy and security during confirmation on the Bitcoin network. -
EVM Compatibility
The network supports the Ethereum Virtual Machine (EVM), allowing developers to seamlessly migrate or build decentralized applications (dApps) from EVM-compatible chains to B² Network, thereby enriching the Bitcoin ecosystem. -
Data Availability Layer (B² Hub)
B² Network introduces B² Hub, the first Data Availability (DA) layer on Bitcoin. It ensures data availability and verifies the legitimacy of transaction execution and state transitions by leveraging Bitcoin's robust security.
