B² Network: Accelerating the Boom of the Bitcoin Ecosystem With B² Hub

B² Network, as a leading Bitcoin Layer 2 and invested by prominent investors including HashKey Capital, OKX Ventures, IDG, KuCoin Ventures, ABCDE, Waterdrip Capital, Satoshi Lab, OGs Fund, Antalpha, and Leland Ventures, has proposed a revolutionary method to verify ZK Rollup commitments on Bitcoin when building a Bitcoin Rollup, making sure B² Rollup keeps the same security level as Bitcoin. It is also positioned as a Bitcoin Layer2 service provider by working with Polygon and Altlayer to expand this validation method to all Bitcoin Layer 2s.

I. B² Network Technical Architecture

Two essential parts make up the technological architecture of the B² Network: the Rollup layer and the Data Availability layer. Collaborating to ensure network stability, these structures form the backbone of the B² Network.

The Rollup layer, powered by ZK-Rollup technology, acts as the execution hub. Components such as the account abstraction module, RPC services, memory pool, sequencer, zkEVM, aggregator, synchronizer, and prover create a central processing hub for user transactions.

The Data Availability layer, which includes B² Hub, the Bitcoin network, and decentralized storage, acts as the primary hub for verification and storage. It ensures great security and dependability by storing, confirming, and validating the availability, integrity, and validity of Rollup data.

II. How does the B² Network Verify Rollup Commitment on Bitcoin

The aforementioned is a general explanation of B² Network’s basic architecture, while the most innovative part is how B² Network verifies its Rollup Commitment on Bitcoin.

B² Network guarantees high-level security for Layer2 in four steps below, with Bitcoin as the settlement layer.

– Conversion from zero-knowledge proof verification procedures to Bitcoin scripts.

– Utilization of Circuit Taproot as the B² Rollup commitment.

– Verify and respond to protocols, using UTXO transactions that issue lock rewards as unlocking scripts, and leveraging Taproot scripts for unlocking;

– Introducing a challenge mechanism.

By adhering to these guidelines, B² Network is able to submit Rollup Commitments on Bitcoin, ensuring data security and availability, thus maximizing security inheritance from Bitcoin amidst Bitcoin Layer 2 solutions.

III. Polygon CDK + B² Hub, B² Network Accelerates the Development of BTC ecosystem through modularization.

B² Network addresses the security issues that other prominent Bitcoin Rollups have encountered. Therefore, B² Network partnered with Polygon and AltLayer to convert this validation technique into B² Hub, a general solution for all Bitcoin Rollups.

This solution combines the strength of both Bitcoin and Ethereum Layer2s, enabling easy construction of a Bitcoin Layer2 with the same security level as Bitcoin. It allows a focused effort on building the application layer and ecosystem, eliminating redundancy in security verification.

By compiling batches and proof data into script, submitting zk proof verification commitments in Taproot form, B² Hub enables any Bitcoin Layer 2 to use verification services from B² Network collaboratively, saving time and reducing costs.

All BTC Layer2 solutions based on “Polygon CDK + B² Hub” will be bridged seamlessly. B² Hub is poised as the central hub in the diverse BTC Layer2 market, accelerating the development of the whole Bitcoin ecosystem.

As of March 8th, the B² Network Buzz event has accumulated a Total Value Deposited of $575 million. The B² Network Alpha testnet has seen 109,000 transactions, while the Beta testnet transactions have reached 7.731 million. There are 1.63 million active addresses, and over 1000 contracts have been deployed. This data robustly validates that B² Network is the most practical Bitcoin Layer 2 solution.

B² Network plans to launch its mainnet this month, with multiple ecosystem applications ready to roll out. In February, B² Network released its ecosystem map, comprising over 50 projects spanning nearly 20 verticals. Their partners include well-known projects, such as Polygon, Babylon, Altlayer, Particle Network, Stakestone, GlowDex, Dego.finance, PolyHedra, Meson.fi and many others, many of which have emerged as rising stars in this current bullish market.

With the rapid growth of the BTC ecosystem, B² Network will provide a more practical technical architecture design, empowering the thriving development of assets, DeFi, NFTs, SocialFi, and other DApps within the BTC ecosystem.
