With the rise of Bitcoin DeFi, modular blockchains, and AI Agent concepts, demand for foundational infrastructure continues to grow. BSquared Network has built a product matrix comprising B² Rollup, B² Hub, Mining², and AI Signal.
Unlike many single-purpose Bitcoin Layer2 projects, BSquared Network's multi-layer architecture decouples execution, data, yield, and AI collaboration into independent modules. Each product can function independently while achieving coordinated scaling through a unified architecture—providing the foundation for Bitcoin DeFi, modular applications, and AI Agents.
BSquared Network uses a modular blockchain architecture, splitting execution, data management, and final settlement across different layers. Traditional blockchains handle all three within a single network, which becomes bottlenecked as applications scale.
In BSquared's design, B² Rollup handles transaction execution and smart contracts, B² Hub manages data availability and ecosystem coordination, and the Bitcoin network provides final settlement and security. Meanwhile, Mining² and AI Signal connect mining resources and AI economy scenarios, respectively. This layered approach lets each module focus on its core role while improving overall scalability and flexibility.
B² Rollup is the core execution layer of BSquared Network and the backbone of the entire ecosystem. It uses a ZK Rollup architecture to offload large-scale transaction computation off-chain, submitting only verification results to Bitcoin—boosting throughput and reducing on-chain load.
When a user initiates a transaction, the Sequencer orders and packages it. The zkEVM then executes smart contract logic and updates the network state. After execution, the system generates a zero-knowledge proof, submits it for verification, and anchors the final state to Bitcoin. This approach lets B² Rollup deliver both scalability and security.
For developers, B² Rollup offers an EVM-compatible environment that supports Solidity smart contracts and existing toolchains, allowing Ethereum-based projects to enter the Bitcoin ecosystem at low cost and driving more applications to deploy on BSquared.
B² Rollup is the compute engine of the entire BSquared ecosystem. Every DeFi protocol, stablecoin system, NFT platform, and AI Agent application depends on the Rollup layer to execute transactions and maintain state.
Data stored in B² Hub originates from Rollup execution results. Mining² on-chain yield distribution relies on Rollup for settlement. AI Signal's recorded data and behaviors also require Rollup verification. Thus, B² Rollup is not just a scaling solution—it's the infrastructure that connects all ecosystem modules.
As the ecosystem grows, B² Rollup's performance and compatibility will directly shape the network's development capacity, making it one of BSquared's most critical products.
B² Hub is BSquared's proposed Layer1.5 data availability layer. Its primary role is to store and manage data generated by the Rollup and coordinate collaboration across ecosystem modules.
In a modular blockchain, the execution layer doesn't permanently store all data, so a dedicated data layer is needed. B² Hub records transaction batches, state updates, and proof information, ensuring network participants can access and verify this data.
Beyond data availability, B² Hub also handles ecosystem coordination. By connecting B² Rollup, Mining², and AI Signal, it becomes the data hub and information exchange center of the BSquared network.
Data availability is essential for secure Rollup network operation. Without access to transaction data, users can't independently verify network state, making B² Hub vital to the entire BSquared ecosystem.
Its independent data layer design reduces the execution layer's burden and improves system scalability. B² Hub also introduces mechanisms like Proof of Signal (PoSg) to build new incentive systems based on data value and network signals.
As the number of ecosystem applications grows, B² Hub will not only manage data but also become key infrastructure for cross-application collaboration and modular expansion.
Mining² is a key BSquared Network module built for Bitcoin mining, designed to connect traditional mining operations with on-chain financial ecosystems.
Bitcoin miners have long relied on block rewards and transaction fees, which typically stay within mining pools and off-chain financial systems. Mining² aims to bridge mining resources with DeFi applications through on-chain infrastructure, enabling miners to participate in a broader range of digital economic activities.
By introducing yield mapping, hashrate resource integration, and on-chain financial mechanisms, Mining² seeks to improve BTC asset utilization and offer miners more ways to engage with the on-chain ecosystem.
Mining²'s core value lies in bridging Bitcoin mining and decentralized finance. Traditional mining income flows are relatively closed, while on-chain finance offers far more asset utilization opportunities.
Through Mining², miner-generated income can flow into liquidity markets, yield protocols, or other financial applications. This not only boosts BTC capital efficiency but also provides more native asset support for Bitcoin DeFi.
From BSquared's strategic perspective, Mining² is a key driver in transforming BTC assets from a mere store of value into on-chain productive factors.
AI Signal is the infrastructure layer built by BSquared for the AI Agent ecosystem. It handles data verification, behavior recording, and collaboration support among intelligent agents.
As AI Agent concepts evolve, more applications are exploring AI-blockchain integration. However, verifying data authenticity and establishing credible behavior records remains a major industry challenge.
AI Signal aims to provide a trusted data environment for AI Agents through blockchain mechanisms, making data sources, execution processes, and results more transparent and traceable.
AI Agents constantly need to gather information, execute tasks, and interact with other systems. AI Signal provides a trusted data layer and verification mechanism for this process.
When an AI Agent generates data, completes a task, or triggers specific behavior, relevant information can be verified on-chain. This improves collaboration efficiency among AI Agents while reducing risks from data forgery and information asymmetry.
For BSquared, AI Signal is not just AI infrastructure—it's a key component connecting the future intelligent economy.
BSquared Network's strength lies in how its core products form a complete collaboration system. B² Rollup handles execution and state, B² Hub provides data availability, Mining² brings mining resources on-chain, and AI Signal builds a trusted data and collaboration environment.
When a user completes a transaction, B² Rollup executes the logic, and data flows into B² Hub for storage and verification. For yield flows, Mining² provides asset access. For AI Agents, AI Signal offers data verification support.
This multi-layer collaborative architecture makes BSquared more than just a scaling network—it's evolving into a comprehensive infrastructure platform for Bitcoin DeFi and AI applications.
Through product collaboration, BSquared Network supports a wide range of scenarios. In finance, developers can build BTC DeFi, lending protocols, stablecoin systems, and yield markets.
In digital assets, BSquared supports NFTs, blockchain games, and digital identity applications. AI Signal provides infrastructure for AI Agent payments, data verification, and on-chain collaboration.

As the ecosystem expands, more modular applications and cross-domain innovations can be built on BSquared Network, further extending Bitcoin's application boundaries.
