With a market value of 13 trillion, most of Bitcoin cannot directly generate benefits, and there are opportunities waiting to be explored. The TVL of ETH L2 exceeds 10% of the market value of Ethereum, indicating a huge market space for BTC L2! Today, I want to introduce the B ² Network, which uses ZK as its core technology, has strong partners and financing background, and is expected to become one of the most feasible Bitcoin L2 solutions. There are also upcoming activities such as B ² Hive and B ² Buzz where rewards can be obtained!
The original intention of Bitcoin's design was to maximize security and decentralization, but it sacrificed scalability and the ability to execute smart contracts. As the user base expands, the problems of network congestion, transaction delays, and soaring transaction fees in the Bitcoin network have become difficult to solve. In addition, with the decrease in miners' economic benefits after halving, the Bitcoin network urgently needs ecological empowerment, and rich on-chain activities to maintain the stability of the number of miners and network security, which has also given rise to a huge demand for BTC L2.
B ² Network is a leading Layer 2 project on BTC, which is an EVM-compatible ZK Rollup. Rollup data and ZK proof verification commitments are recorded on the BTC network and ultimately confirmed through a challenge-response mechanism. The project adopts a modular design architecture, including the Rollup layer and Data Availability (DA) layer, namely B ² Hub. The Rollup layer is responsible for submitting and processing user transactions, while the DA layer is responsible for storing copies of aggregated data and verifying aggregated zk proofs.
The Rollup of B ² needs to undergo state transition verification and data availability storage verification through B ² Hub, and then submit the commitment to the Bitcoin network. Therefore, the security and decentralization of B ² Hub are very important. B ² Network has chosen a PoS mechanism to protect B ² Hub. In order to ensure the security of the consensus mechanism, BTC Stak has also been introduced. In addition, developers are developing the LSD/LRT project based on B ² PoS to release liquidity and integrate with other DApps.
The advantages of B ² Network include the following:
①Designed B ² Hub to uniformly submit data availability proofs and state transition proofs to the Bitcoin network without affecting the operation of Bitcoin's own proofs, to prevent Bitcoin from being adversely affected by 2nd layer extensions;
②Providing an off-chain transaction platform that supports Turing-complete smart contracts to improve transaction efficiency and reduce costs;
③Enhancing transaction privacy and security through zero-knowledge proof technology.
Ecology
B ² Network's partners are all leading projects and are constantly expanding its ecological footprint. It ensures security through Babylon's staking and timestamp protocol, effectively avoiding remote attacks. It recently announced a partnership with Polygon Labs to create the first integrated Polygon CDK BTC use case, which means that in the future, developers can choose the combination of "Polygon CDK + B ² Hub" to launch their own BTC rollup!
Financing
On January 25th of this year, B ² Network received seed round financing from well-known investment institutions such as @HashKeyCapital, @OKXVentures, @IDG Capital, @ABCDE Labs, @waterdripfund.
On April 17th, B ² Network launched its mainnet. By participating in B ² Hive, B ² Buzz, and B ² Discovery, users can obtain early B ² tokens at a low cost, which will be introduced one by one.
Before starting, we need to bridge BTC assets to the B ² mainnet. After entering the website, connect to the OKX or Unisat wallet, enter the amount of BTC to be bridged, and click "Deposit Funds".

I. B ² Hive:
B ² Hive is a key component of B ² PoS, and users can protect the B ² network by staking BTC. In return, users can receive B ² token rewards. After Babylon BTC Stake mainnet goes live, B ² users can also receive rewards from Babylon.
The staking rewards started at 4 am UTC on May 3rd, and the allocation rules are as follows:
①A block is generated every 2 seconds, and each block produces $0.3375 worth of $B ², distributed according to the staker's proportion. The total supply of $B ² is 210 million.
②Users can stake and unstake at their own discretion at any time. Unstaking only requires 24 hours.
③The minimum staking amount is 0.001 BTC, and more types of assets will be supported for staking.
The staking process is also relatively simple. First, you need to bridge the Bitcoin in your BTC wallet to the B ² mainnet. After entering the staking website, connect your wallet, enter the amount of tokens to be staked, and then click "Stake". If you want to unstake, enter the unstaking amount in the "withdrawal" section shown in the diagram, and then click "Unstake".

II. B² Buzz
B² Buzz covers activities related to assets and on-chain events, including but not limited to bridge lottery, Runes Fest, staking alliance, and the widespread Bitcoin network. It is explicitly stated that 30% of the tokens will be distributed to users through Buzz, with the bridge activity accounting for 0.5%. Starting from April 30th, Buzz assets will support bridging to EVM-compatible chains, and the functionality to bridge Bitcoin will also be opened soon!
To participate in Buzz activities, simply enter the website, connect your wallet, enter the invitation code, and follow @BSquaredNetwork. Enter the amount of tokens you want to bridge to the B² network on the interface, and click "Bridge". To maximize earnings, we need mining components, and now through the OKX wallet, we can directly trade B² Buzz mining NFTs.

III. B² Discovery
B² Network has released the "B² Mainnet Discovery and Bitcoin Halving Commemorative Event," which includes a series of exploration activities. There are currently two ongoing activities, and by completing the corresponding tasks, you can receive airdrop rewards!
B² Discovery URL: https://bsquared.network/discovery/
Okapi event URL: https://app.okapi.xyz/discovery/campaign/b-ecosystem-discovery…
UXLink event URL: https://dapp.uxlink.io/discover/detail?id=1779158074653667348
① Okapi event: After entering the event URL, connect your wallet, write a review for B² Network to create an Okapi Vault, then return to the main interface, select Okapi Drops, and then choose B² Network.
Participate in other activities within the platform to receive additional rewards.
② UXLink event: In order to seamlessly onboard more web2 users to web3, B² Network and UXLink have launched this event. After entering the website, follow the instructions to connect your wallet, follow and retweet to complete the task, then click on "UXLINK NFT" in the upper right corner to mint NFTs, and receive triple airdrop rewards from UXLink, B² Network, and LayerCraft!
Summary: B² Network has cleverly designed a modular architecture and greatly expanded the scalability of the BTC ecosystem by using zk rollup and B² Hub while ensuring security! It is backed by investments from well-known institutions and partnerships with leading projects, all of which contribute to making B² one of the most feasible Bitcoin L2 solutions. For users, it also offers various activities to acquire B² tokens at a low cost, making it worth considering for early adoption!
