**B² Network** is a [Bitcoin](https://iq.wiki/wiki/bitcoin)-focused [blockchain](https://iq.wiki/wiki/blockchain) project that combines a zero-knowledge [Layer 2](https://iq.wiki/wiki/layer-2), a data-availability and consensus layer, and [Bitcoin](https://iq.wiki/wiki/bitcoin) finance applications. It aims to expand [Bitcoin’s](https://iq.wiki/wiki/bitcoin) use beyond a store of value, including as a means of settlement for [decentralized applications](https://iq.wiki/wiki/decentralized-application) and autonomous [artificial-intelligence agents](https://iq.wiki/wiki/ai-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](https://iq.wiki/wiki/bitcoin)-based assets.[\[1\]](#cite-id-gx6dprmzwu)​[\[2\]](#cite-id-70xxqclqkh)​[\[3\]](#cite-id-yz9v1z4c9i)​[\[4\]](#cite-id-5xf7cconft)​

## Overview 

B² Network’s architecture centers on B² Rollup and B² Hub. B² Rollup is an [Ethereum Virtual Machine (EVM)](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible execution layer: users and developers can run [smart contracts](https://iq.wiki/wiki/smart-contract) and batch transactions off-chain, while zero-knowledge validity proofs are submitted to the network’s [Bitcoin](https://iq.wiki/wiki/bitcoin)-oriented settlement infrastructure. The design is intended to increase transaction throughput and reduce costs while anchoring the system to [Bitcoin](https://iq.wiki/wiki/bitcoin).[\[1\]](#cite-id-gx6dprmzwu)​[\[3\]](#cite-id-yz9v1z4c9i)​[\[4\]](#cite-id-5xf7cconft)​

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](https://iq.wiki/wiki/bitcoin) [Layer 2](https://iq.wiki/wiki/layer-2) networks. The network’s documentation describes its security model in terms of Taproot and [zero-knowledge proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps), while its website names Proof of Signal (PoSg) and modular Application Shading as elements of the Hub’s design.[\[4\]](#cite-id-5xf7cconft)​[\[1\]](#cite-id-gx6dprmzwu)​

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](https://iq.wiki/wiki/bitcoin)-anchored settlement and verification.[\[4\]](#cite-id-5xf7cconft)​

## Bitcoin Finance and AI Applications

B² Network frames its development around making [Bitcoin](https://iq.wiki/wiki/bitcoin) usable in financial applications and in transactions among [AI agents](https://iq.wiki/wiki/ai-agents). Its documentation presents [stablecoins](https://iq.wiki/wiki/stablecoin) 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.[\[2\]](#cite-id-70xxqclqkh)​

The project’s named components extend beyond the rollup and Hub. [CoinMarketCap](https://iq.wiki/wiki/coinmarketcap) describes B² Buzz as a Bitcoin-yield platform offering [staking](https://iq.wiki/wiki/staking), [liquidity mining](https://iq.wiki/wiki/liquidity-mining), and structured products. It describes MiningSquared as a mining-pool solution that combines Bitcoin [mining](https://iq.wiki/wiki/mining) with yield products, allowing participants to allocate mined BTC to B² Buzz strategies or other financial products.[\[3\]](#cite-id-yz9v1z4c9i)​

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](https://iq.wiki/wiki/coingecko) characterizes the project’s AI direction as involving signal-driven networks and native AI signal layers.[\[1\]](#cite-id-gx6dprmzwu)​[\[4\]](#cite-id-5xf7cconft)​

## Tokenomics

B² Network’s native token is $B2. The network identifies it as a governance and rewards token; [CoinGecko](https://iq.wiki/wiki/coingecko) additionally describes it as the asset used to pay [Layer 2](https://iq.wiki/wiki/layer-2) [gas](https://iq.wiki/wiki/gas) and as part of B² Hub’s consensus mechanism. [CoinMarketCap](https://iq.wiki/wiki/coinmarketcap) and CoinGecko list a maximum supply of 210 million B2.[\[6\]](#cite-id-9w2qka221m)​[\[4\]](#cite-id-5xf7cconft)​[\[3\]](#cite-id-yz9v1z4c9i)​

CoinGecko describes governance as involving B² Hub consensus participants in a decentralized structure. B² token [staking](https://iq.wiki/wiki/staking) went live in May 2025. Announcements described staking on B² Network and [BNB Chain](https://iq.wiki/wiki/binance-smart-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](https://iq.wiki/wiki/babylon), [Aptos](https://iq.wiki/wiki/aptos), CoreDAO, [Sei](https://iq.wiki/wiki/sei), and Echo. A May 2025 social-media post claimed an annual percentage yield above 151%.[\[5\]](#cite-id-1zlkfidxae)​[\[6\]](#cite-id-9w2qka221m)​

## Ecosystem

B² Network’s ecosystem listings cover [Bitcoin](https://iq.wiki/wiki/bitcoin) finance, cross-chain infrastructure, rollup services, and digital-asset custody. Echo is described as providing liquid-staking-token integration, liquidity provision, and [Bitcoin](https://iq.wiki/wiki/bitcoin) yield strategies; [River](https://iq.wiki/wiki/river) as a cross-chain capital-coordination layer powered by its [satUSD](https://iq.wiki/wiki/satusd) [stablecoin](https://iq.wiki/wiki/stablecoin); and Avalon Labs as developing BTC-backed lending, a [Bitcoin](https://iq.wiki/wiki/bitcoin)-backed [stablecoin](https://iq.wiki/wiki/stablecoin), yield-generating accounts, and a credit card.[\[7\]](#cite-id-hj8h4w8wap)​

Other listed projects address interoperability, restaking, and lending. BridgeM is described as connecting [Bitcoin](https://iq.wiki/wiki/bitcoin) and [Ethereum](https://iq.wiki/wiki/ethereum) [Layer 2](https://iq.wiki/wiki/layer-2) networks, while Pell Network focuses on [Bitcoin](https://iq.wiki/wiki/bitcoin) and liquid-staking-derivative yield and security for [Bitcoin](https://iq.wiki/wiki/bitcoin) [Layer 2s](https://iq.wiki/wiki/layer-2). [Bedrock](https://iq.wiki/wiki/bedrock-dao) 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.[\[7\]](#cite-id-hj8h4w8wap)​

Lombard is listed as connecting Bitcoin to [decentralized finance](https://iq.wiki/wiki/defi) through LBTC, which the page described as being in private beta.[\[7\]](#cite-id-hj8h4w8wap)​
