introduction
Today, blockchain technology is changing with each passing day, Bitcoin is not only widely accepted as a digital asset, but its underlying technology is constantly evolving and innovating.With the gradual expansion of Bitcoin’s ecosystem, various Layer2 solutions have sprung up like rain, which aims to improve the scalability, efficiency and security of the Bitcoin network.This article will explore multiple innovative Bitcoin Layer2 projects. Through the detailed analysis of the technical principles, team backgrounds, financing conditions, and development roadmaps of these projects, we will understand how they promote the innovation and development of Bitcoin ecosystems.
BABYLON: Cross -chain pledge and Bitcoin economy security
Babylon uses the native pledge of Bitcoin (BTC) through cryptography to provide other blockchain provides a security guarantee for equity (POS).This mechanism not only brings chain income to BTC, but also attracted widespread market attention.
In terms of technology realization, Babylon’s pledge process depends on cryptography completely, without a third -party bridge or custodian.BTC pledges can achieve pledge through transactions with two UTXO outputs.The first UTXO is written in the lock script. After the expiration, the pledged person can unlock the BTC with a private key; the second UTXO is transferred to the temporary Bitcoin address.Code science standards.When the pledgers run the POS chain node and verify the only effective block, sign it with the EOTS private key.
If the pledged operator operates honestly, only one signature of one effective block will be awarded by the POS chain; if you try to sign two blocks at the same time, the EOTS private key will be launched, and anyone can use the private privately.The BTC of the key to the pledged pledge achieved the penalty, prompting the pledged to maintain honesty.BABYLON also provides BTC timestamp service, and the checkpoint data of any blockchain checkpoint will be uploaded to the OP_RETURN of BTC to enhance security.
Babylon’s pledge is a cross -chain pledge. The pledged Bitcoin retains the script on the Bitcoin network. The pledgers can specify the verification person to earn benefits on the corresponding POS chain.By pledged the BTC to provide economic security for other POS chains, BTC can obtain revenue without leaving the main network. It has opened a new track for BTC pledge and will greatly change the BTC ecological gameplay.
According to DEFILLAMA data, the current BTC market size is more than $ 10 billion, of which the active income is 4 billion US dollars, and the yield is between 0.01%and 1.25%. Generally, it is necessary to entrust a third -party CEFI institution or bridge or package BTC.The pledge rewards of POS blockchain are usually ranging between 5%and 20%.Through Babylon’s pledge business, BTC does not need to host to third -party institutions, and can get 50 times the traditional BTC income, which has huge growth potential.
Nevertheless, most BTC holders are passive holders, 25%of BTCs have not been used for more than 5 years, and 67%of BTC holding time for more than 1 year. Therefore, it is difficult to persuade BTC holders to participate in pledge.BABYLON is undergoing pledge of testing networks and is planned to launch the main network test on May -June. It has not yet announced the launch of the liquidity pledged BTC voucher assets.
Babylon was founded in 2022 by David TSE and Fisher YU professor of Stanford University.Professor YU is a member of the American Academy of Engineering and is famous for its fair scheduling algorithm in the field of wireless communication.On December 7, 2023, Babylon completed a $ 18 million financing, Polychain Capital and Hack VC led, Framework Ventures, Polygon Ventures, Okx Ventures, and iosg Ventures.On February 24, 2024, the Binance Lab announced the investment in BABYLON.In May 2024, Babylon completed a new round of financing of $ 70 million and Paradigm led.
Chakra: Bitcoin re -pledge agreement driven by ZK
Chakra is a Bitcoin re -pledge agreement driven by ZK, aiming to establish a safe Bitcoin POS system.By using ZK-Starks and middleware chain, the Chakra network has established a native modular paradigm for the expansion of the BTC ecology.On April 30, Chakra announced the completion of a new round of strategic financing. Starkware, Bixin Ventures, Cogotent Ventures, etc. participated in the investment, and the specific amount and valuation information was not disclosed.
Chakra aims to solve liquidity and interoperability challenges, and releases the huge value of Bitcoin.With the help of Chakra, other BTC second -layer solutions can focus on the execution layer without paying too much attention to the settlement of Bitcoin infrastructure.
Chakra networks unlock liquidity through shared settlement layers and obtain economic security, and then empower the BTC ecological participants.The projects and DAPPs of BTC Layer2 will benefit from the strong liquidity network effects in this security and vibrant ecosystem.
By generating UTXO containing time locks, Chakra allows Bitcoin to pledge without transferring assets without transferring assets.Chakra uses stark to implement the proof system.Compared with Snark, Stark provides a zero -knowledge certificate solution that does not require credible settings. Chakra uses Starks technology to realize ZK light clients.And security.By introducing Cairovm, Chakra further enhances the scalability and transparency of the system.
Nubit_org: Agreement to expand the availability of Bitcoin data
Nubit is a protocol for BTC expansion data usability (DA) scenario. It organizes a DA chain similar to Celestia by running POS consensus and regularly upload Nubit’s DA data to the main BTC chain.Nubit has no intelligent contract capabilities and requires Rollup based on its DA.The user uploads data to Nubit. These data are confirmed to enter the “soft confirmation” state by POS consensus, and then Nubit uploads the data root to the BTC main chain to complete the final confirmation.Users need to upload data labels in the BTC main chain to query the original data in the Merkel Tree of Nubit nodes.
At present, there are already 100 BTC L2 on the market. If you choose to upload the DA to the BTC block, even if the BTC block is filled, the main network can only support up to 20 L2.Therefore, how to connect with BTC and use its security guarantee, there is a huge narrative gap, Nubit’s DA re -packaging idea is an interesting solution.
Nubit has carried out the first round of Pre-Alpha Testnet. Users can earn points or run light nodes by linked BTC accounts.The first round of the test network has ended and plans to conduct the second phase of the test network.Nubit’s angel round financing participants include Boundce Finance and BRC20 founder Domo, and completed $ 3 million Pre-SEED round financing. DAO5, OKX Ventures, Primitive Ventures and others participated.
Lorenzo: BTC’s liquidity pledge protocol
Lorenzo, based on Babylon, is a liquidity pledge protocol that provides a rapid deployment service of L2-As-A-Service, which aims to reduce the pledgee’s penalties and release the liquidity of pledged BTC assets.The pledgers deposit the BTC into Lorenzo’s multi -signal address, which can obtain the equal amount of STBTC on its chain as a liquidity proof and receive the pledge income.
The Lorenzo chain itself is shared by Babylon Bitcoin. It is an EVM compatible Bitcoin L2. In the future, it will use a modular method to help more BTC L2 deployment.The Lorenzo chain is the direct interoperability of these L2 chains.Currently, Lorenzo has announced cooperation with Babylon, Boundcebit, etc., and plans to launch a test network based on the COSMOS architecture.It is currently in Babylon’s fourth test network cooperation to conduct liquidity re -pledge testing.
According to ROOTDATA, Lorenzo was invested by Binance, MH Ventures, and NGC Ventures. The specific details were not announced.Currently Lorenzo announced the start of the pre -pile Babylon event and jointly organizing the Bitlayer Mining Gala Heiter Mine Festival. Users can pile the BABYLON activity page to pile the BTC to get STBTC. All Lorenzo will receive BabyLon as soon as Lorenzo participated in BABYLON.Praising, but due to the upper limit of the Babylon pledge, the actual pledge progress may be determined by the pledge limit that may exist in BABYLON.

Paul Sztorc, the proposal of DriveChain, is the founder and CEO of Layrtwolabs. He is a former researcher and statistician of Yale University. He is also a senior practitioner of Bitcoin. He has elaborated the concept of DriveChain in BIP300 and BIP301.
DriveChain is a BTC -side chain technology. Through the hash rate custody mechanism and miner scoring system, it will achieve the large -scale side chain expansion of Bitcoin without changing the core safety and decentralized characteristics of Bitcoin.The basic mechanism is to create a new Bitcoin address. Any funds sent to this address will be locked. Only when all miners agree can these funds be expected.The miners reached a consensus through the “scoring” system. Once the score of a certain transaction is high enough, the transaction will be released, and the funds will be transferred from the side chain to the main chain.
DriveChain allows Bitcoin network to use new use cases through side chain experiments, such as issuing assets, complete private transactions, status blockchain contracts, etc., without having to sacrifice the core security and decentralized characteristics of Bitcoin.The roadmap of the project has begun to implement, and the test network has Launcher of Linux, Mac and Windows.The code is open source, the completion is better, and the update is frequent.

Conclusion
The number of Bitcoin Layer2 projects is growing rapidly, and there are currently nearly 100. In general, it can be divided into four categories.
The first category is the EVM -side chain. This is the largest number of projects. Most of them are mostly deployed EVM chains by Rollup modularized methods. Using POS consensus, the entrepreneurial threshold is low, and strong capital operation capabilities are required to effectively start.Some of these projects have tried to introduce the latest modularization solutions such as ZK.
The second type of project continues Bitvm’s design ideas and innovates in verification methods, which introduces BTC security to a certain extent.However, this type of project has chosen to go online to develop an EVM + POS main network to develop the ecology. It is essentially no different from the first type of EVM side chain. There are certain narrative expectations and often obtain some high financing. This is also VC.Circuit for centralized investment.
The third type of project focuses on BTC’s deposit pledge, and uses BTC as the assets pledged by POS. It introduces the concept of BTC pledge similar to Eigenlayer, trying to attract more BTC savings.The leading project BABYLON has innovated the cryptographic level on the pledge of BTC. Most of the other projects are innovated at the business level, such as introducing BTC pledge into CEFI to create more benefits.We believe that the mainstream of the BTC pledge will be the mainstream of the future ecology. Before the realization of BITVM, the pledge security guarantee will solve the BTC narrative problem of the above BTC EVM side chain.
The fourth type of projects have been explored more in the native BTC, such as further developing UTXO models, and trying to create new side chain asset binding solutions based on UTXO.BTC’s native exploration also includes the continued exploration of the joint mining side chain.There are also a few projects trying to promote BTC upgrades and introduce more script operators to expand the BTC ecology, which is currently the most DEGEN line.
The BTC ecosystem is in the rapid development stage, and various innovative projects are constantly emerging to solve the challenges of the Bitcoin network in terms of scalability, security and efficiency.From Babylon’s cross -chain pledge to Nubit’s extended data availability, from the Lorenzo’s liquidity pledge protocol to Bitsmiley’s comprehensive DEFI protocol. These projects have jointly promoted the diversified development of the Bitcoin ecosystem through different technical paths and business models.Through continuous attention and participation in these cutting -edge projects, communities and developers will be able to better grasp the future development trend of blockchain technology and jointly build a more efficient, secure, and diverse blockchain ecosystem.
