BMAN:ZK互操作龙头Polyhedra的3个重要技术突破
作者:BMAN,ABDCE创始人;来源:作者推特@BMANLead
最近互操作三巨头接连上线,将掀起互操作赛道的小阳春。
Polyhedra代币ZK 3月上线;Wormhole代币W 4月上线;LayerZero预计Q2上线。
其中Polyhedra是唯一的ZK选手,也抢到了ZK这个漂亮的Ticker,完成了Polychain领投的10亿美金融资,成为名副其实的ZK互操作龙头。
过去3年,Polyhedra团队20多位博士及密码学专家围绕ZK互操作已取得了数十项突破,Polyhedra发明的DeVirgo和Virgo是目前最快的ZKP协议之一。普通用户用笔记本或手机无需从服务器下载大量数据(众所周知这一致是业界难题)即可成为Prover。
deVirgo具有近乎完美的线性可扩展性,在具有M台计算机的分布式计算网络中,证明生成时间可以缩短近乎M倍。此外,在deVirgo中,跨分布式计算网络的通信在Virgo中的主要计算(GKR部分)中被最小化。使用deVirgo,zkBridge的证明生成速度可以进一步提升,比使用单线程Virgo要快100倍。
过去3年,Polyhedra基于zk,做出了3个重要的技术突破:
1、zkBridge和zkLightClient
Polyhedra发明了行业首个zkBridge,zkBridge脱胎于2022年网络安全顶会ACM CCS论文,指导教授是美国国家科学院院士. A16z Crypto首席科学家,Vitailk的密码学技术顾问Dan Boneh:

过去3年链上用户通过zkBridge在数百万个钱包,25条链和 80多个生态系统中发送了超过 2000 万笔跨链交易。
Polyhedra发明的ZK轻客户端zkLightClient还为 Layer1 和 Layer2 互操作提供超过450万条消息传输。互操作三巨头之一的LayerZero也在使用zkLightClient作为默认的去中心化验证网络(DVN)。
2、以太坊全节点证明:
Polyhedra利用ZK增强BLS 签名验证,显着减少以太坊验证节点和全节点之间的通信大小。这一创新增强为以太坊更精简和扩容铺平了道路,zk轻客户端zkLightClient使每个验证者都可以签署每个块,允许单个zk-proof来验 512 个BLS签名,仅需要200到300 字节的通信。
Polyhedra创造的单时隙最终性(SSF)还显着减少以太坊的延迟。 它与先进的ZKP deVirgo和改进的签名方案结合,增强以太坊的速度和用户体验,也是Vitalik最看重的以太坊里程碑之一。
3、比特币互操作:
比特币生态在发展的初期,已经呈现数十条Layer2群雄逐鹿的格局,但数十条Layer2也急需可以互操作的基础设施,Polyhedra是在比特币生态互操作走的最前的龙头。
zkBridge已经支持了比特币生态的最大的可互操作性,连接比特币钱包、Layer2、DeFi和基础设施。甚至在比特币和其他链之间,也可以基于ZK进行去信任的互操作。
结语:
过去3年,Polyhedra发明了最快的ZK算法deVirgo,连接超过 25 个网络,完成了4000 万个zk证明,2000万笔跨链交易,且每笔交易只需要1条消息,相比之下,Wormhole 需要 10 亿条消息来验证总共 300 万笔交易,Polyhedra是当下最高效的互操作龙头项目。
在未来几年,我们期望在数学和ZKP领域取得1000倍的性能提升,这将使得区块链完全互操作的愿景得以实现。
未来链与链之间将实现:
1、资产的互操作;2、信息的互操作;3、协议的互操作。
未来A链的协议,可以自动和和B链的协议可组合和可互通,链与链之间将成为万链互联的状态。而Polyhedra就像其中文「多面体」一样成为万链互联的基础设施。
Author, founder, source, author, Twitter, the three giants of interoperability have recently launched one after another, which will set off the interoperability track. The Xiaoyangchun token will be launched on a monthly basis, and the token is expected to be launched on a monthly basis. Among them, the only player has also grabbed this beautiful $100 million financing, which has become a veritable interoperability leader. In the past year, many doctors and cryptographers in the team have made dozens of breakthroughs around interoperability, and the invention is one of the fastest protocols at present. Ordinary users do not need to download from the server for notebooks or mobile phones. As we all know, a large number of data is a problem in the industry, which can become nearly perfect linear scalability. In a distributed computing network with computers, the generation time of the certificate can be shortened by nearly times. In addition, the communication of the mid-span distributed computing network is minimized in the main computing part of the network, and the generation speed can be further improved by twice as fast as that of using a single thread. Last year, based on an important technological breakthrough, the industry first network security summit theory was invented. Professor Wen is the cryptology technical consultant of the chief scientist of the National Academy of Sciences. In the past years, users have sent more than 10,000 cross-chain transactions in millions of wallet chains and multiple ecosystems, and the light client has also provided more than 10,000 messages for interoperability. One of the three giants of interoperability is also using Ethereum as the default decentralized verification network. The enhanced signature verification significantly reduces the communication between the Ethereum verification node and the whole node. This innovation and enhancement paves the way for the simplification and expansion of Ethereum. The light client allows each verifier to sign each block, allowing a single signature to be verified only in bytes. The single-slot finality created by the communication also significantly reduces the delay of Ethereum. It is also one of the most important milestones in Ethereum to enhance the speed and user experience of Ethereum. Bitcoin interoperability has shown dozens of competing patterns in the early stage of development. However, dozens of infrastructures that are also in urgent need of interoperability are the foremost leaders in bitcoin ecological interoperability, and have supported the biggest interoperability of bitcoin ecology. Connecting bitcoin wallets and infrastructures can be based on the conclusion of interoperability between bitcoin and other chains. In the past year, the fastest algorithm was invented to connect more than 10,000 networks and complete 10,000 cross-chain transactions, and each transaction only needs 100 million messages to verify a total of 10,000. This transaction is the most efficient interoperability leading project at present. In the next few years, we expect to achieve double performance improvement in mathematics and fields, which will realize the vision of complete interoperability of blockchain. In the future, the interoperability of assets and information will be realized between chains, and the protocols of future chains can be automatically combined and interoperable. Chain to chain will become the state of interconnection, and just like its Chinese polyhedron, it will become the infrastructure of interconnection. 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
