BSQUARED Network (B² Network) is the leading Layer 2 project on BTC. It successfully introduced smart contracts into BTC and unlocked the potential value of the 832 Billion market value BTC.This project will provide a new platform for innovative applications such as DEFI, NFT, and BTC derivative assets in the BTC ecosystem.
1. Unlock BTC ecological value
The current Bitcoin problem:
The performance of Bitcoin: The main focus of Bitcoin’s original design is decentralization and security, not the peak of performance.Due to its 10 -minute block interval and limited block size, the throughput of Bitcoin is severely limited, and a small amount of transactions can be treated per second.With the continuous expansion of the Bitcoin user group, this problem has become increasingly prominent, leading to network congestion, transaction delay and transaction costs.
The Turing of Bitcoin is incomplete: Bitcoin’s script language is deliberately designed as non -Turing, which aims to enhance the security and simplicity of the network.This means that Bitcoin cannot implement complex smart contracts locally, thereby limiting its potential in the field of decentralized applications.
Trading costs: With the growth of network traffic, users must pay higher transaction costs to ensure that their transactions are prioritized.This dynamics make small or frequent transactions in economics unrealistic.
B² Network is the EVM Composition Layer2 on the BTC, which allows developers and consumers to directly experience Native Bitcoin Two -layer network:
-Su a chain trading platform that supports Turing’s complete smart contracts to improve transaction efficiency and reduce costs.
-Instly integrate zero -knowledge proof (ZKP) technology with Bitcoin’s TAPROOT, ensure the privacy and security of transactions.
-The network aims to develop Bitcoin into a dynamic platform and build a stage for innovative applications such as DEFI and NFT. It is not only suitable for traditional bitcoin assets, but also for emerging Bitcoin derivative assets.
2. The design and advantage of B² Network
The technical architecture of B² Network is shown in the figure below, including two layers of structures: rollup layer, data available (DA) layer.B² Network aims to redefine users’ views on the second -level solution of Bitcoin.
B² uses ZK-Rollup as the ROLLUP layer.The ZK-Rollup layer adopts the ZKEVM solution and is responsible for performing user transactions and output-related certificates in the second layer network.The user’s transaction is submitted and processed at the ZK-Rollup layer.The user’s status is also stored on the ZK-Rollup layer.The batch proposal and the generated zero -knowledge proof is forwarded to the data available layer for storage and verification.
The availability layer includes distributed storage, B² nodes and Bitcoin networks.This layer is responsible for the copy of the Rollup data permanently, verify the zero -knowledge certificate of ROLLUP, and finally executes the final confirmation on Bitcoin.
Distributed storage is a key aspect of Bt Network. It is a repository as ZK-Rollup user transactions and its related certificates.By decentralized storage, the network has fundamentally improved security, reduced single -point failure, and ensures the unknown data.
In order to ensure the availability of data, B 可 also writes a TapScript script to the Bitcoin network in each block of Bitcoin, as shown below.The script anchor the data path and zero -knowledge proof of effective storage in the decentralized storage of Rollup in this period. This process is controlled, and 6 transactions are generated per hour.Therefore, users will compare the Taproot script data on the transaction and Bitcoin Layer1 one by one to ensure the final credibility of the Rollup data.
In addition, Be Network will also transform the zero -knowledge certification process of B² nodes into a Bits commitment. Writing the Bitter commitment to the Bitcoin network.Make challenge unlock rewards through the challenge mechanism, as shown below.
Through the above design, Bt Network realizes the following advantages:
-The transaction cost is reduced by 50 times, and the speed increases by 300 times
-It can interact by using UNISAT, XVerse, Metamask, OKX and other familiar wallets
-In abstraction of accounts, you can use the original BTC (BC1P …) or ETH (0x) address for access
-The cost is low:
-& gt; The cost of Bl Rollup Layer is the operating cost of the chain itself. When demand is increased, you only need to increase RPC services and ZKEVM Prover horizontally
-& gt; The cost of B l Da Layer is the node operating cost of B² NODES.Increase in rollup transactions will not affect B² Nodes
-& gt; Layer1’s cost is the transaction fee of BTC itself.Each BTC block contains a Layer1 transaction, so the cost is fixed.
It is worth noting that Bt Network will also upgrade in the future. B² NODES upgrades to B² Hub. B² Hub will build a two -layer Rollup developer and project party service for all hopes to build a two -layer Rollup on the Bitcoin network, providing data based on Bitcoin network dataAvailable layers and status conversion verification/proof systems.
3. How to activate the BTC ecology through economic incentives?
● SEQUENCER pledge: Sequencer participates in the sequence verification election by pledged BSQ, and users can entrust the BSQ to the sequence verification device.
● Bitcoin miner incentive: Bitcoin miners’ contribution computing power can get BSQ token.Participating in the ZK proof of Bitcoin can get BSQ (the profit of miners will generate new income after halving).
● Assets cross -chain incentives: ● When users cross the chain to B² Rollup, such as BTC, ETH, BRC20 and other assets, the user will get BSQ income (if the user locks the assets to the Defi of Layer 2 to provide liquidity, you can get higherincome).
● Storage node incentive: Storage nodes store the Rollup data copy and submit the storage ZK to obtain BSQ income.
● B● HUB handling fee: BSQ will be the native currency of B² Hub. The use of B² Hub to deploy ZK-Rollup will charge BSQ as a transaction fee.
● Governance: BSQ holders can vote for future agreement upgrades.
● Trading fee discount: You can enjoy discounts with BSQ payment GAS fees.
● Revenue sharing: users who pledge BSQ can get the division of platform GAS costs.
4. Looking forward to the future
The launch of B² Network has introduced smart contracts for BTC, providing a new platform for innovative applications such as DEFI, NFT, and BTC derivative assets in the BTC ecosystem.It is expected that in the near future, the GAS cost of BTC asset transactions will be significantly reduced, and the easy programming of Layer 2 will also bring richer application scenarios to BTC.
