Technical Architecture and Core Objectives of B2 Network
B2 Network is the first ZK-Rollup Layer2 solution built on the Bitcoin network, aiming to address long-standing performance bottlenecks. Traditional Bitcoin suffers from low throughput, high fees, and lack of Turing completeness, making it unsuitable for complex financial applications. B2 Network introduces a modular design that separates the transaction execution layer (Rollup) from the data availability layer (DA).
Technically, the Rollup layer uses zero-knowledge proof (ZK-Rollup) and is compatible with the Ethereum Virtual Machine (EVM), allowing developers to port DeFi applications seamlessly. The data availability layer (DA) uses the B2 Hub to anchor transaction data to the Bitcoin mainnet, leveraging Taproot scripts to ensure data immutability. This design retains Bitcoin’s security while expanding its capabilities, enabling BTC to evolve from a payment tool to infrastructure for smart contracts, NFTs, and derivatives.
Strategic Partnership with Binance Wallet and PancakeSwap
On April 30, 2025, B2 Network announced a new token generation event (TGE) in partnership with Binance Wallet and decentralized exchange PancakeSwap. Users need to accumulate Alpha Points to participate in the subscription, with rules to be disclosed before the launch. This partnership is significant—Binance expands Web3 access through the Alpha ecosystem, while PancakeSwap taps into native BTC liquidity via B2 Network to standardize BTC DeFi usage.
For regular users, holding BTC, ETH, or trading Alpha tokens allows accumulation of Alpha Points, unlocking early access to B2 tokens. This lowers participation barriers and could attract more Bitcoin holders into DeFi. With Bitcoin’s market cap exceeding $832 billion and most assets idle, B2 Network’s DeFi applications could unlock this latent liquidity.

B2 Token Economic Model and Network Incentives
B2 is the native token of B2 Network, structured around network incentives and governance. Validators must stake B2 to participate in sequencer elections, while storage nodes earn rewards for storing Rollup data. Additionally, users providing liquidity when bridging BTC, ETH, and other assets are rewarded with B2.
On the governance side, B2 holders can vote on protocol upgrades, and staked tokens share platform revenue. Since its mainnet launch in March 2024, B2 Network’s total value locked (TVL) has surpassed $663 million, with over 7.73 million transactions processed on its testnet—indicating early market validation.
Future Challenges and Market Expectations
Despite its innovations, B2 Network faces two key challenges:
-
ZK proof generation compatibility with Bitcoin scripts needs long-term validation.
-
Cross-chain asset bridges may face regulatory scrutiny. For example, while Babylon protocol’s BTC staking mechanism enhances security, its non-custodial model’s legality varies across jurisdictions.
From an industry perspective, B2 Network could reshape the Bitcoin Layer2 landscape. Ethereum’s Layer2 ecosystem is mature, but Bitcoin’s is still emerging. If B2 Network achieves multi-Rollup scalability and becomes a general-purpose DA provider, it will attract more developers to build on Bitcoin.

A Key Step in Bitcoin’s Ecosystem Evolution
B2 Network’s partnerships with mainstream platforms signal Bitcoin’s shift from “digital gold” to a “financial application layer.” With ongoing tech upgrades and ecosystem expansion, Bitcoin may move beyond value storage to become a core infrastructure for open finance. For investors and developers, this evolution brings both opportunities and potential risks in terms of technology and regulation.
