随着比特币扩容讨论的加热,过去半年里比特币的二层解决方案层见迭出。

理想中的比特币二层应当不仅继承比特币的安全特性,还需构建一个可扩展且支持编程的链上金融基础设施。

Bitlayer引领了基于BitVM的比特币二层解决方案,采用分层虚拟机技术(Layered Virtual Machine),利用零知识证明(zkp)和乐观验证(op)机制来支持各类计算。 此外,Bitlayer还通过OP-DLC和BitVM桥搭建了双通道双向锁定资产桥,从而实现与比特币第一层相等的安全性。

于此同时,一条链的成功少不了生态的建设。Bitlayer目前已与80个项目达成生态构建与合作,意向TVL已经突破10亿美金,

一、 Bitlayer 的设计以及优势

Bitlayer的主要技术创新在于采用最新的BitVM计算范式和OP-DLC桥。

与其他比特币第二层解决方案相比,Bitlayer旨在解决第二层面临的三个核心问题,并提出了相应的解决方案:

  1. 无需信任的双向锚定(Trustless 2-Way Peg) — — 结合OP-DLC与BitVM桥,引入了超越传统多签模式的创新模型。

  2. 第一层验证(Layer 1 Verification) — — 通过BitVM继承比特币的安全性。

  3. 图灵完备性(Turing-Completeness) — — 支持多种虚拟机,实现了100%与以太坊虚拟机(EVM)兼容的环境。

设计架构

乐观验证

Bitlayer 采用与 Optimistic Rollup 相同的乐观执行机制,结合MATT提案(Merkelize All The Things)的架构方案。系统将基于欺诈证明和挑战-响应协议,不会对比特币的共识规则进行任何修改。

我们知道将一个大型程序提交到Taproot地址需要大量的链下计算和通信,但是其在链上的占用非常小。只要双方合作,他们就能执行任意复杂的、具有状态的链下计算,而不会在链上留下任何痕迹。仅在出现争议的情况下,才需要在链上执行。如有参与者证明交易无效性,交易就会被回滚。

Bitlayer通过链下计算和通信,然后以压缩格式将状态和零知识证明一起提交到一层区块链,减少了数据负载和相关成本,实现二层的扩容。

构建无需信任的跨链桥

桥接资产的安全性一直是第二层解决方案的关键,核心问题在于资产控制的方法。最常见的行业方法是第二层平台运营商基于MPC-TSS(多方计算和阈值签名方案)或Schnorr技术设置多签名账户,用户将其资产转入这些账户。这种传统方法导致用户完全失去对其资产的控制, 而Bitlayer利用OP-DLC + BitVM技术,使得用户可以保留对其资产的部分控制,my assets are my own。

通过双通道双向挂锁桥,Bitlayer不仅能满足第一层用户对BTC存取操作的自主控制需求,也保证了原生二层用户能够顺利提现。

分层虚拟机

为实现金融功能如抵押借贷、Swap和复杂合约,比特币二层需具备可编程执行能力的虚拟机(VM)。

Bitlayer引入分层虚拟机(LVM),前端执行智能合约与后端零知识证明生成解耦,支持多种智能合约和零知识证明验证器。借助Taproot,简化了ZK-STARKs验证,保证安全性与计算灵活性。

通过在 LVM 框架内集成对 EVM 的支持,开发者可以无缝地利用现有基于 EVM 的智能合约,同时从分层架构提供的增强执行能力中受益。

二、Bitlayer 生态百花齐放

在生态建设方面,依托强大的合作资源,目前Bitlayer的生态合作伙伴高达80家,其中包括基础设施、稳定币、钱包、检索等。我们相信在主网上市以后,Bitlayer的生态会呈现百花齐放的状态。

目前的生态伙伴包括:StarkWare、Hacken、AWS Cloud、Ankr、Polyhedra、Macaron、Trustin、Babylon、Particle Network、Meson、Nubit、BitSmiley、TokenPocket、Xverse、Flash Protocol、Umoja.xyz、RunesTerminal、Lamina、NFTGO、Giants Planet、Surf Protocol 、Tria、Tonka Finance、Ordimint和Caliber。

为了激励开发在Bitlayer上建设,3月29日Bitlayer 官方公布系列生态激励计划,首期活动Ready Player One将向生态构建者和项目方发放价值5000万美元的公链代币奖励,并鼓励Dex、Wallet、NFT Marketplace、Lending、LSD、Bridge、Stablecoin等类型项目在Bitlayer上建设。

目前Bitlayer还在于180家潜在合作伙伴谈深度合作,并且正在筹备一系列吸引用户参与Bitlayer社区建设的激励活动,包括推出Galxe和TaskOn忠诚度积分和生态项目打榜活动,以及官方NFT等。

三、展望未来

路线图

距离比特币减半到来还有不到10天的时间, Bitlayer 主网V1将于近期启动。

在未来的1–2年中,我们坚信未来能看到更多比特币原生的创新在Bitlayer构建与部署。Bitlayer能借助比特币东风,成为比特币生态发展风向标。

The source is heated up with the discussion of bitcoin expansion. In the past six months, the two-tier solution layer of bitcoin has emerged one after another. The ideal two-tier solution layer of bitcoin should not only inherit the security characteristics of bitcoin, but also build an extensible and programming-supporting chain financial infrastructure, leading the two-tier solution of bitcoin based on hierarchical virtual machine technology, using zero-knowledge proof and optimistic verification mechanism to support all kinds of calculations. In addition, a dual-channel and two-way locking asset bridge is built through the and bridge to realize bitwise. At the same time, the success of a chain is indispensable to the ecological construction. At present, the ecological construction and cooperation intention have been reached with 10 projects, and the design and advantages have exceeded 100 million US dollars. The main technological innovation lies in adopting the latest computing paradigm and bridge. Compared with other bitcoin second-tier solutions, it aims to solve the three core problems faced by the second layer and put forward corresponding solutions. Two-way anchoring and bridge without trust introduces an innovative model that transcends the traditional multi-sign mode. The first-level verification of type I realizes the environment design architecture compatible with Ethereum virtual machine by inheriting the security of Bitcoin and Turing completeness. Optimistic verification adopts the architecture scheme combined with the same optimistic execution mechanism. The system will be based on fraud proof and challenge response protocol, and will not modify the consensus rules of Bitcoin. Source technical white paper: We know that submitting a large program to an address requires a lot of offline calculation and communication, but it takes up a lot of space on the chain. Often, as long as both parties cooperate, they can perform any complicated offline calculation with status without leaving any trace on the chain. Only when there is a dispute, they need to perform it on the chain. If a participant proves that the transaction is invalid, the transaction will be rolled back through offline calculation and communication, and then the status and zero-knowledge proof will be submitted to the first-tier blockchain in a compressed format, reducing the data load and related costs, realizing the expansion of the second floor and building a cross-chain bridge without trust to bridge the security of assets. The most common industry method is that the second-tier platform operators set up multi-signature accounts based on multi-party computing and threshold signature scheme or technology, and users transfer their assets to these accounts. This traditional method leads to users completely losing control of their assets, but the technology enables users to retain some control of their assets. The dual-channel bidirectional padlock bridge can not only meet the independent control needs of the first-tier users for access operations. It also ensures that the native two-tier users can successfully withdraw the hierarchical virtual machine. In order to realize financial functions such as mortgage lending and complex contracts, the virtual machine with programmable execution ability is introduced into the second tier of Bitcoin. The front-end execution of intelligent contracts and the back-end zero-knowledge proof generation are decoupled to support a variety of intelligent contracts and zero-knowledge proof verifiers. By simplifying the verification, the security and computational flexibility are guaranteed. By integrating the support within the framework, developers can seamlessly use the existing intelligent contracts. Benefiting from the enhanced execution ability provided by the hierarchical structure, two ecological flowers blossom in ecological construction, relying on strong cooperation resources. At present, there are as many ecological partners as possible, including infrastructure stability, currency wallet search, etc. We believe that the ecology will be in a state of blooming after listing on the main network. The current ecological partners include and in order to stimulate development, the first phase of a series of ecological incentive plans was officially announced last month, and the public will be distributed to the ecological builders and project parties with a value of million dollars. At present, projects such as chain token reward and encouragement are still under construction. At present, potential partners are talking about in-depth cooperation, and a series of incentive activities are being prepared to attract users to participate in community construction, including launching and loyalty points and ecological project ranking activities, as well as the official road map for the future. The main network will be launched in the near future. In the next year, we firmly believe that more bitcoin native innovations can be built and deployed with the help of bits. Coin Dongfeng has become the vane of bitcoin ecological development. Recently, it has received $10,000 in financing. Famous angel investors including CEO, co-founder, CEO, chief technology officer and founder have all participated in this round of financing, and the seed round of financing has received strong support from ecosystem partners, including. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
