B² Network is a Bitcoin-based Layer 2 platform that uses zero-knowledge proof rollups to enable smart contracts and decentralized applications. It supports EVM compatibility, cross-chain functionality, and account abstraction, including control via Bitcoin keys, Ethereum keys, or email-based identities. Transaction data and validity proofs are committed to Bitcoin using Taproot, with a challenge-response mechanism for final verification. The network includes decentralized storage and sequencer selection through a DPoS-like model, aiming to extend Bitcoin’s utility into areas such as DeFi and NFTs.
B² Network is a Layer 2 scaling solution built on Bitcoin that uses zero-knowledge proof technology to support smart contracts and decentralized applications. It implements a rollup model based on verification commitments, with rollup data and proofs recorded on Bitcoin via Taproot scripts. The network is EVM-compatible and supports both Bitcoin and Ethereum address accounts. It also includes native account abstraction, allowing control via Bitcoin keys, Ethereum keys, or email-based identities. Additional infrastructure includes decentralized storage with zk-proof validation, and a decentralized sequencer model inspired by Delegated Proof of Stake (DPoS).
B² Network is used to improve the scalability and utility of Bitcoin by enabling faster, lower-cost transactions and supporting the deployment and migration of decentralized applications, including DeFi, NFTs, and SocialFi. Its zkEVM enables compatibility with Ethereum-based DApps, and the platform supports cross-chain interaction through its bridge functionality. Transaction verification occurs on Bitcoin through a challenge-response system linked to Taproot-anchored commitments. Users interact through abstracted accounts with configurable permissions, while data availability is maintained via decentralized storage nodes and validator systems.
The B2 token is the native utility and governance token of the BSquared Network, a Layer-2 scaling solution for Bitcoin. It is used to pay transaction fees within the B² Hub and its rollups, incentivize validators through staking, and enable community participation in protocol governance. B2 also supports future functionality, such as sequencer staking and interoperability with additional rollups. The token has a capped total supply of 210 million, with allocations designated for ecosystem incentives, investors, team members, and liquidity provision, governed by structured vesting schedules to ensure long-term sustainability.
