B2 Network
B² Network is a Bitcoin-focused blockchain project that combines a zero-knowledge Layer 2, a data-availability and consensus layer, and Bitcoin finance applications. It aims to expand Bitcoin’s use beyond a store of value, including as a means of settlement for decentralized applications and autonomous artificial-intelligence agents. The network describes its broader goal as building infrastructure for an AI-driven economy in which agents can hold wallets and transact using Bitcoin-based assets.[1][2][3][4]
概述
B² Network’s architecture centers on B² Rollup and B² Hub. B² Rollup is an Ethereum Virtual Machine (EVM)-compatible execution layer: users and developers can run smart contracts and batch transactions off-chain, while zero-knowledge validity proofs are submitted to the network’s Bitcoin-oriented settlement infrastructure. The design is intended to increase transaction throughput and reduce costs while anchoring the system to Bitcoin.[1][3][4]
B² Hub is described as a “Layer 1.5” layer for consensus, data availability, and verification. It supports B² Rollup and is also presented as infrastructure for other Bitcoin Layer 2 networks. The network’s documentation describes its security model in terms of Taproot and zero-knowledge proofs, while its website names Proof of Signal (PoSg) and modular Application Shading as elements of the Hub’s design.[4][1]
CoinGecko describes B² Network’s Zero Knowledge Proof Verification Commitment (ZPVC) mechanism as using inscriptions to secure the integrity of off-chain transactions. Together, the rollup and Hub are intended to move execution away from Bitcoin’s main chain while retaining Bitcoin-anchored settlement and verification.[4]
Bitcoin Finance and AI Applications
B² Network frames its development around making Bitcoin usable in financial applications and in transactions among AI agents. Its documentation presents stablecoins as a way to provide predictable pricing and liquidity for agents, and describes the network’s aim as combining Bitcoin, AI agents, and stablecoins into a settlement system for an AI economy.[2]
The project’s named components extend beyond the rollup and Hub. CoinMarketCap describes B² Buzz as a Bitcoin-yield platform offering staking, liquidity mining, and structured products. It describes MiningSquared as a mining-pool solution that combines Bitcoin mining with yield products, allowing participants to allocate mined BTC to B² Buzz strategies or other financial products.[3]
The network has also promoted infrastructure for AI agents and models to transact in a Bitcoin-based economy. Its AI Signal product is described as infrastructure for an AI-native Bitcoin economy, and CoinGecko characterizes the project’s AI direction as involving signal-driven networks and native AI signal layers.[1][4]
代币经济学
B² Network’s native token is $B2. The network identifies it as a governance and rewards token; CoinGecko additionally describes it as the asset used to pay Layer 2 gas and as part of B² Hub’s consensus mechanism. CoinMarketCap and CoinGecko list a maximum supply of 210 million B2.[6][4][3]
CoinGecko describes governance as involving B² Hub consensus participants in a decentralized structure. B² token staking went live in May 2025. Announcements described staking on B² Network and BNB Chain without staking or unstaking fees or a lockup, with a one-day unstaking cooldown. B² Network also described the service as integrated with Babylon, Aptos, CoreDAO, Sei, and Echo. A May 2025 social-media post claimed an annual percentage yield above 151%.[5][6]
生态系统
B² Network’s ecosystem listings cover Bitcoin finance, cross-chain infrastructure, rollup services, and digital-asset custody. Echo is described as providing liquid-staking-token integration, liquidity provision, and Bitcoin yield strategies; River as a cross-chain capital-coordination layer powered by its satUSD stablecoin; and Avalon Labs as developing BTC-backed lending, a Bitcoin-backed stablecoin, yield-generating accounts, and a credit card.[7]
Other listed projects address interoperability, restaking, and lending. BridgeM is described as connecting Bitcoin and Ethereum Layer 2 networks, while Pell Network focuses on Bitcoin and liquid-staking-derivative yield and security for Bitcoin Layer 2s. Bedrock is listed as a multi-asset liquid-restaking protocol, and Capy Finance as a restaking and lending protocol on B² Network that supports borrowing and lending against Bitcoin and several types of crypto assets.[7]
The ecosystem page also lists AltLayer, an open protocol for rollups; APRO Oracle, an oracle provider in the Bitcoin ecosystem; OpenBit, which supports cross-chain circulation and decentralized-finance services; and Cygnus Finance, which describes its system as connecting non-EVM networks such as Bitcoin with the EVM ecosystem. Lombard is listed as connecting Bitcoin to decentralized finance through LBTC, which the page described as being in private beta.[7]
