{"version":1,"id":"b2-network","title":"B2 Network","summary":"B² Network is a Bitcoin Layer 2 ecosystem that combines zero-knowledge rollups and data-availability infrastructure to support Bitcoin applications, DeFi, and AI-agent transactions.","content":"**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)​\n\n## Overview \n\nB² 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)​\n\nB² 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)​\n\nCoinGecko 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)​\n\n## Bitcoin Finance and AI Applications\n\nB² 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)​\n\nThe 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)​\n\nThe 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)​\n\n## Tokenomics\n\nB² 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)​\n\nCoinGecko 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)​\n\n## Ecosystem\n\nB² 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)​\n\nOther 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)​\n\nThe ecosystem page also lists [AltLayer](https://iq.wiki/wiki/altlayer), an open protocol for rollups; [APRO](https://iq.wiki/wiki/apro) [Oracle](https://iq.wiki/wiki/oracle), an oracle provider in the Bitcoin ecosystem; OpenBit, which supports cross-chain circulation and decentralized-finance services; and [Cygnus Finance](https://iq.wiki/wiki/cygnus-finance), which describes its system as connecting non-[EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) networks such as [Bitcoin](https://iq.wiki/wiki/bitcoin) with the [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm) ecosystem. 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)​\n","categories":[{"id":"projects-and-protocols","title":"projects-and-protocols"}],"tags":[{"id":"Layer2"},{"id":"Infrastructure"},{"id":"DeFi"},{"id":"AIInfrastructure"},{"id":"Payments"}],"images":[{"id":"QmRhSthHLVgt5BvhMGRcq2UAX3faqkqftdE2TCiygj3Um6","type":"image/jpeg, image/png"}],"media":[],"metadata":[{"id":"references","value":"[{\"id\":\"gx6dprmzwu\",\"description\":\"B² Network Official Website\",\"timestamp\":1794629054445,\"url\":\"https://www.bsquared.network/\"},{\"id\":\"70xxqclqkh\",\"description\":\"B² Network Documentations\",\"timestamp\":1794629059909,\"url\":\"https://docs.bsquared.network/\"},{\"id\":\"yz9v1z4c9i\",\"description\":\"CoinMarketCap: $B2\",\"timestamp\":1794629067843,\"url\":\"https://coinmarketcap.com/currencies/bsquared-network/\"},{\"id\":\"5xf7cconft\",\"description\":\"CoinGecko: $B2\",\"timestamp\":1794629080008,\"url\":\"https://www.coingecko.com/en/coins/bsquared-network\"},{\"id\":\"1zlkfidxae\",\"description\":\"B² Network Blog\",\"timestamp\":1794629085509,\"url\":\"https://blog.bsquared.network/\"},{\"id\":\"9w2qka221m\",\"url\":\"https://x.com/BsquaredNetwork\",\"description\":\"B² Network on X\",\"timestamp\":1794628139599},{\"id\":\"hj8h4w8wap\",\"description\":\"B² Network Docs: Ecosystem\",\"timestamp\":1794629098443,\"url\":\"https://www.bsquared.network/ecosystem/\"}]"},{"id":"twitter_profile","value":"https://x.com/BsquaredNetwork"},{"id":"website","value":"https://www.bsquared.network/"},{"id":"coinmarketcap_url","value":"https://coinmarketcap.com/currencies/bsquared-network/"},{"id":"coingecko_profile","value":"https://www.coingecko.com/en/coins/bsquared-network"},{"id":"main-image-origin","value":"{\"imageId\":\"QmRhSthHLVgt5BvhMGRcq2UAX3faqkqftdE2TCiygj3Um6\",\"originalId\":\"QmRhSthHLVgt5BvhMGRcq2UAX3faqkqftdE2TCiygj3Um6\"}"},{"id":"commit-message","value":"Create the B2 Network wiki"}],"events":[{"type":"DEFAULT","title":"B² Network token generation event","date":"2025-04-01","description":"B² Network completed its token generation event, and the B2 token launched.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"744bb324-8e99-457d-a04c-c363bed31649"},{"type":"DEFAULT","title":"B² Network staking went live","date":"2025-05-01","description":"B² Network announced that B2 staking was live.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"a9895950-5895-4918-b67d-83c65858a200"},{"type":"DEFAULT","title":"U2 stablecoin system launch","date":"2025-09-01","description":"B² Network announced the launch of its U2 stablecoin system for using Bitcoin in global settlement.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"3b926ade-a204-4ae4-837c-fa772084f9ac"},{"type":"DEFAULT","title":"B² Hub introduction","date":"2025-09-01","description":"B² Network introduced B² Hub as AI-native consensus and infrastructure anchored on Bitcoin.","link":null,"multiDateStart":null,"multiDateEnd":null,"id":"8941b44c-2bd5-4101-aff7-44af0d8bdfbb"}],"linkedWikis":{"founders":[],"blockchains":["bitcoin","binance-smart-chain"],"speakers":[]},"user":{"id":"0x8af7a19a26d8fbc48defb35aefb15ec8c407f889"},"author":{"id":"0x4a2bc97afbf41a2cbf4b4628f63420682ff4cf2a"},"language":"en","operator":{"id":"0x4a2bc97afbf41a2cbf4b4628f63420682ff4cf2a"}}
