    Emma introduced Ultrain trust computing in her speech, and described her entrepreneurial history. She also made a few suggestions for entrepreneurs on the conference: First of all, to acquire first-hand and second-hand knowledge, accumulate your own big database, and love learning more cross-border knowledge. Secondly, be an interesting person, cultivate interest in international affairs, politics, history, religion, culture, and art. If you have energy, you can also work hard to cultivate a deep hobby and maintain the mind love nature and sports.

    alt text

    Third, to fully understand your enthusiasm and goals, and to determine whether you are suitable for starting a business, you need to understand that entrepreneurship is difficult. It means long-term investment and responsibility, and requires entrepreneurs to have very comprehensive capabilities. Entrepreneurship requires an adventurous spirit and an attitude to change results. To make the impossible possible, you must also understand that entrepreneurship is likely to fail, gain nothing, and waste years of youth and financial resources. Finally, entrepreneurs can find their own public hobbies, mostly to make contribution for society, just as Emma has always supported Cambodia's ACCB animal protection base.

    December, 11th, 2019. Beijing

    SECOO Group (NASDAQ: SECO) and Ultrain successfully held “The Global Luxury Consumption Alliance” Launch Press Conference jointly today. It is a critical strategic cooperation between the two organizations to seriously bring the luxury goods authentication and transaction model to the next level, adopting AI and blockchain as the innovative technology infrastructure. The “Global Luxury Consumption Alliance Chain” is an alliance to welcome all important luxury industry stakeholders, including brands, designers, online and offline retail channels, regulators and customs, and all the way to the end users together to best operate the logistics and authenticity issues, to lower the cost of trust among all parties and to bring the highest efficiency of transaction and satisfaction for the end consumer. This major initiative shows how much SECOO cares about high-tech enabled innovation to push the boundaries of business models and to not only serve its own businesses, but also to bring benefits to the entire luxury consumption industry globally.

    According to McKinsey’s “2019 China Luxury Consumption Report”, in 2018, Chinese luxury consumption at home and abroad reached close to 120 billion USD, which is one-third of global luxury consumption. Online sales are projected to increase by two to three times from the current scale by 2025. Nonetheless, anti-counterfeiting traceability is still a major pain point of the global luxury industry when it comes to endless “cheap copy” and “high imitation”. Public Blockchain technology with its truly decentralized, tamper-prooftraceability with extremely customizable application logic on the chain has provided a solution. The characteristics of its technology offer a new dimension to luxury identification and quality guarantee.

    In June 2018, SECOO has already launched its first version and the industry’s first luxury blockchain application for commercial use. Every product on chain has a unique ID attached to the physical good. By using the SECOO App, users can scan the code to query the anti-counterfeit traceability information of the products.

    In April 2019, SECOO continued to increase the authenticity R&D effort and jointly established the “SECOO AI Laboratory” with the Academy of Sciences Computing Institute. As Secoo already owns the largest identification center with high quality big data in Asia, the Ai-Model-Driven identification of products can be realized and users are provided with a faster, safer and more reliable identification method that brings reliable results.

    The cooperation between Secoo and Ultrain is an example of the long term dedication of Secoo into R&D and innovation.

    Led by SECOO and many other crucial partners from the industry, the "Global Luxury Consumption Alliance" currently provides traceability information on chain with privacy protections built-in. Through today’s partnership with Ultrain, SECOO Blockchain will obtain three major core tech competencies which excel globally to achieve its goals, they are ”VDF-based R-PoS consensus algorithm”, “random dynamic sharing technology”, and “programmable zero-knowledge proof on chain”. With these core know-hows, the GLCA will completely solve the core pain points of low TPS, high cost, and lack of privacy protection in the commercial implementation of blockchain technology. A high-performance, low-cost, high-security blockchain service platform is formed today for the luxury industry. The GLCA will continue to invite more upstream and downstream players to join, to contribute to a better identification alliance and transaction efficiencies to all luxury goods consumers.

    Experts have pointed out that, in the future, blockchain alliance competition will not only be based on the improvement of the underlying technology, but also the benefits of the distribution mechanism of the alliance and long-term fairness issues. Referring to Libra, launched by Facebook, its alliance association-like governance and public-oriented architecture have shown the embryonic characteristics of the public alliance chain.

    Zhiyu(Emma)Liao, Ultrain cofounder

    Ultrain co-founder & CEO Ray Guo commented, “based on Ultrain's block-chain technology, the “Global Luxury Consumption Alliance” has massive decentralized nodes capabilities, on-chain data privacy protection capabilities, and high concurrency and tamper-resistant computing capabilities, which provides a solid foundation for the construction of this alliances”. Emma Liao, Co-founder of Ultrain mentioned: “blockchain/trust computing technology has great value in the luxury industry. Transparency and synchronized operation can optimize the industry's value chain in many ways, new way of engagement and incentive methods are implemented, which result with utmost convenience and benefits to all end users. I hope our cooperation with SECOO will make a significant impact and valuable contribution to the global luxury consumption field. "

    Zhonghui Lei, Vice President of SECOO stated, “the strategic cooperation with Ultrain is a crucial step of our innovation upgrade.” “SECOO will also invite more partners to build this alliance with multiple professional services for the luxury industry. We believe that on boarding C2C second-hand trading platforms empowered by it has a great merit and high-end consumer communication, customer loyalty programs among all other services.”

    1 区块链技术是什么

    当我们谈到区块链技术,大多数人想到的可能是去中心化的记账,但什么是去中心化的记帐呢?我们先看记帐这个词,”记”是指记录编写,“帐”广义上可以指数据,“记账“就是对数据的存储和计算操作;而什么是去中心化呢?就是组成区块链系统的众多计算机,并不是由一个中心化的机构或组织拥有,而是由众多机构、组织、群体等共同拥有的。所以,从本质上说,区块链技术就是一个去中心化计算机网络基础上,对数据进行存储或操作的技术,该技术的特点是,任何数据存入到这个系统后,该数据都不可销毁,不可篡改。

    2 区块链技术的商业价值

    2.1 区块链技术的商业价值本质

    区块链技术对比传统的分布式数据库技术,有什么优点呢?核心就是区块链技术是去中心化的,而传统的分布式数据库技术是中心化的。

    去中心化对比中心化有什么好处呢?我们以新浪举例,新浪是一个中心化的信息平台,大众只能阅读新浪提供的新闻,如果新浪篡改或删除已发布的新闻,大众是很难感知的;如果是一个去中心化的信息平台,在新闻发布后,没有任何人,包括平台自身,能篡改或删除这些已经发布的新闻,所以大众可以完全信赖这些新闻发布后没有被篡改过。

    正是基于这种不可篡改的区块链技术特点,我们可以建立一个低成本的信任中心,解决商业社会中信任成本高昂的痛点。

    信任是商业社会的基础,建立信任是商业交易的前提,缺乏信任,任何商业交易合作关系都不可能长久。在商业社会发展早期,信任是依赖血缘关系,在私人人际关系的基础上建立的,影响范围有限,且需要大量的时间去培育,成本高昂。

    而后,基于“契约”、“合同“做为束缚,以法律和制度为保障,通过违法必罚的法律逻辑所形成的违法成本预期,我们建立了制度信任,制度信任是现代商业社会运行的基本准则和基石。制度信任有效扩大的信任的应用范围,但是由于其需要一整套的社会规章、制度、法条做保障,其运行成本依然高昂。

    而随着区块链技术的出现,基于不可篡改这个技术特点,人类历史上第一次出现了不依赖第三方主观意志的客观信任,实现了基于机器保证的机器信任。数据保存在区块链上后,就没有任何人或机构可以篡改该数据,基于机器或者说算法的保障,大众可以信任该数据的真实可靠。把这里的数据换为商业社会中常见的合同或者说商业利益分配规则,就可以通过区块链技术保障该利益分配规则的真实、透明、可靠、有效、可信,同时基于区块链技术的特点,我们无需一整套的社会制度去保障,该利益分配规则会在区块链平台上自动计算并执行,从而极大的降低了商业社会在交易执行时的信任成本。

    总的来说,区块链信任创造性地扩大了信任的范围,降低信任的成本,进一步推动了人类信任客观化的进程,为更大范围内的全球一体化协作开辟了新的可能。

    2.2 商业信任的进一步分析

    在分析区块链商业场景前,我们不妨再考察一下商业语境下的信任。信任是商业交易或交换关系成立的基础,其核心是交易双方或多方商业利益分配的规则,涉及到交易关系,那就存在着交易的甲乙双方。抽象来看,交易关系分为两种:

    l 一种是一方强势,比如甲方强势,那乙方如果希望交易成立,就需要完全信任甲方,甲方是这个交易关系中的强信任源;

    l 一种是双方均势,这时双方的信任关系是弱的,甲乙双方都是弱信任源,如果希望达成交易,需要依靠更多的约束和成本(比如商品社会的契约体系)来建立信任,否则就很难建立交易关系;

    在这里,我们再介绍一下“信任源”以及其强弱的定义。“信任源”就是在交易关系中,可以向对方提供信任背书的能力;在商业实践过程中,我们发现在商业交易关系中,占据行业强势地位,可以制定行业利益分配规则,可以提供行业信用背书,场景中其他方都能够信任的企业或机构,可以视为强信任源;不占据行业强势地位,无法提供行业信用背书的企业或机构,我们称为弱信任源;比如供应链金融场景中,某央企做为行业龙头企业,每年向10家中小企业下达采购订单20亿,该10家企业又向100家中小企业下达采购订单;银行可以根据订单金额对这110家企业提供供应链金融服务,但贷款金额的认定,最终一定是追溯到该央企的订单金额,实际上依赖的是该央企的信用背书,在这里我们称该央企为该业务场景中的强信任源,中间接单的中小企业由于并不能提供充足的信用背书,我们称为弱信任源。

    2.3 区块链技术应用的商业场景分析

    从本质上说,区块链技术是为了多机构和组织间进行协作时,降低互相间信任成本而诞生的技术,我们可以从大到小来分析,哪些商业场景需要建立信任,需要建立什么强度的信任:

    2.3.1 基于全球共识信任背书的商业场景

    基于全球共识的商业场景,是全球一体化协作的商业实现,是全球经济一体化的实现目标,为实现这个目标,需要能建立全球性的共识,比如全球公民的共识,或全球国家间的共识。在全球化迅猛发展的今天,类似的商业场景已经逐步出现了:

    A. Facebook的Libra项目

    Libra项目本质上是希望建立一个超主权的世界性货币,可以在世界范围内流动,用于价值交换和结算。这就需要在全球范围内,包括全球的组织,机构和个人,建立对Libra价值的共识和信任,能够接受其用于交易和清算。在这种场景下,无法存在一个强的信任源(除非建立世界国家),在联盟中的所有方都是弱信任源,需要合作建立具备公信力的联盟。

    B. 国家间的大宗商品贸易平台

    我们设想一个这样的场景,多个主权国家之间,希望不基于某一种特定法币(因为存在过度依赖单一法币被单向收割的情况),进行大宗商品的直接交易,建立一个国家间大宗商品贸易平台。由于各个主权国家间存在的天然不信任(国与国之间不存在永恒的朋友,只有永恒的利益),该平台无法由单一一个国家或企业建立,因为这样该国家或企业就可以控制该平台上的数据(引导平台规则对己方有利),相当于必须完全信任该国家或企业。在这种场景下,也无法存在一个强的信任源,在联盟中的所有方都是弱信任源,需要合作建立更为平权的联盟。

    2.3.2 国家主权级信任背书的商业场景

    中国央行近期准备发行的人民币数字货币就是最好的例子。DC/EP( Digital Currency Electronic Payment)是中国自己的数字货币,它的定位和人民币一样,只是以数字货币的形式表现出来的。DC/EP和人民币一样,由中国政府提供信任背书,由于中国政府做为一个强信任源存在,DC/EP中做为参与方的各家商业银行完全信任这个强信任源即可,所以在DC/EP的场景中,存在二级发行架构,在央行发行M0货币层面,央行做为一个强信任源存在,各商业银行信任该信任源即可;所以我们现在看到的DC/EP的技术架构,在央行层面采用的是中心化的技术架构,而在商业银行层面则建议采用区块链技术架构。

    2.3.3 自然垄断性行业信任背书的商业场景

    自然垄断性行业,在一个行业中,若由一家企业生产和供应整个市场的产品和服务,其总成本小于由两家以上企业供应同等数量产品和服务的成本之和,则意味着该行业在制度上确保垄断的供应是有经济效率的,理论上称此类行业为自然垄断行业。在中国,垄断性行业包括石油石化、烟草、电信、电力、武器、铁路、航空、银行等8个行业。

    在这些行业中,天然存在一家或多家巨头,他们联合占据了市场大半的份额,拥有控制行业上下游,制定行业利益分配规则的话语权,他们可以做为行业中的强信任源存在。在大部分时候,因为其一家独大的地位,他们并不需要与其他公司联盟构建商业生态,其他公司按其指定的规则行事即可;

    但在两种情况下,他们需要建立联盟,

    第一种情况,跨行业合作:以我们实际接触过的供应链金融场景举例,A医院每年由200家左右的供应商供应近10亿人民币的各种物料,供应商们希望用医院的采购订单从B银行进行融资,B银行需要确认订单有效,但医院在这时不愿意对订单进行确权,此时,可以构建A医院,B银行和众多供应商间的联盟,在其中共享订单数据,而B银行可以基于这些订单数据以及历史订单记录,对符合条件的供应商提供融资。在这种情况下,B银行需要进行跨行业的合作,并建立跨行业的信任,此时就可以通过区块链技术,与A医院和多家供应商一起构建一个联盟,实现基于订单的供应链金融的业务。在这种情况下,往往还是存在一家做为强信任源,由其推动商业的落地,在本例中B银行就是该强信任源。

    第二种情况,行业巨头间的合作:在自然垄断的情况下,行业中仅存在一家巨头的情况越来越难以被政府和民众接受,更多的情况下行业中会同时存在多家巨头,有时多家巨头之间出于降低行业成本,提升行业效率的目的,需要在建立信任的基础上进行合作,这里的典型就是R3联盟。R3区块链联盟成立于2015年9月,创始成员包括巴克莱银行,毕尔巴鄂比斯开银行(BBVA),澳大利亚联邦银行,瑞士信贷,高盛,摩根大通,苏格兰皇家银行,道富银行,瑞银集团等9家公司,目前已经有数十家国际银行和金融机构加入,成员遍及全球。其致力于通过区块链技术降低银行间复杂的结算、清算等核心业务场景的成本。在这种情况下,联盟成员可以视为是弱信任源,需要共同合作寻求联盟。

    2.3.4 松散企业联盟间信任背书的商业场景

    除了自然垄断性行业外,还存在着大量的充分市场竞争的行业,包括科研、制造(机械、纺织等)、物流、零售、文化娱乐(教育、文学、IP、游戏)、医药生化、食品、地产、农牧渔、服务业(餐饮、旅行)等。在这些行业中,并不存在着一家独大的情况,所以也并不存在由一家或几家可以制定行业利益分配规则的情况。当这些企业间希望建立联盟时,面临的一个核心问题就是如何建立互信。这时,这些联盟成员都是弱信任源,需要共同形成联盟。

    与普通大众的认知相反,企业间的这种信任往往是非常难以建立起来的。以我们合作的一家国内头部加盟制快递公司举例,快递总部已经提供完善的快递单结算系统,可以每日与各区加盟的快递商进行结算,但各区加盟商还是会每天用本子把自己当天发送的快递件信息记录下来,并与总部的结算系统进行对账,核心就是加盟商并不信任总部的系统,总觉得会错结或漏结快递单。这还是在一个加盟体系下的情况,如果是更松散的没有法律上的商业绑定关系的联盟,建立信任更是困难,基本是无法建立的。

    正是因为这个原因,在传统的商业环境和技术条件下,在充分市场竞争行业希望形成类似的商业联盟生态,是非常困难和投入极大的,类似阿里巴巴是投入上百亿建立了基于支付体系的信任体系后,才完成了电商商业生态的构建。但在新的商业环境和技术条件下,能否通过区块链技术,低成本的构建类似的商业生态呢?

    在我们的商业实践中,有类似想法的企业很多,我以一家与我们合作的新三板上市公司举例。该公司的主要业务是提供生物质能源,就是把木材、麦秆等等这些东西处理后代替煤,进行燃料的一个替换升级,该技术在前几年已经被中国认定为是零碳排放技术,能有效地节约能源,降低碳排放量,保护环境。在供能过程中,他们可以对节省的碳排放量进行统计,将减少的碳排放量在碳排放交易所进行交易,对企业产生一个新的收入。

    这种新的商业模式面临的问题是,他们提供的锅炉基本上都是小型锅炉,如6吨、8吨这种体积,但碳排放交易基本是50万吨起。所以,他们需要把所有锅炉燃烧后的减排数量收集在一起,统一和碳排放交易所之间进行批量交易。

    但这个数据到底由谁来统计呢?如果是该公司它本身的系统去统计的话,碳排放交易所不会认可,因为公司自己有可能修改数据谋取利益;如果找第三方统计,第三方可能与该公司进行串谋,也不可信;这个商业模式需要极高的信任成本才能成立,基本就不可行了。

    此时,区块链技术提供的零成本的信任能力就可以很好的解决这个问题。我们与该公司共同合作落地了一套碳排放区块链解决方案,该公司的锅炉上安装有名叫热质仪的IoT设备,用于记录每天锅炉的燃烧量,我们通过无线传输的技术,可以通过该设备直接把燃烧的热量数据写到区块链上并存储。通过这个数据,可以很方便地推算出碳减排量。由于区块链的不可篡改特性,碳排放交易的参与各方都可以认定该数据的真实、有效和可靠,该商业模式就可以落地了。

    该平台建成后,行业内类似的生物质能源公司都可以用加盟的形式加入到该联盟,使用该平台的能力实现碳排放交易,形成一个充分竞争环境下的联盟平台。区块链技术在这里通过技术建立了一个低成本,强信任源的信任中心,支撑了该商业模式的落地。

    3 我们需要什么样的区块链技术来支持这些商业场景

    区块链技术,从本质上是用来降低多机构和组织间的信任成本。但信任并不一定需要依赖区块链技术来建立,如果机构和组织间已经形成了一个强信任源,则区块链在这里起到的作用较为有限,主要用于减少联盟间的信任摩擦,提高信任传递的效率,降低信任成本;如果机构和组织间都是弱信任源,通过传统的中心化技术基本无法解决这个问题,区块链技术可以很好的用较低的成本建立一个不依赖主观第三方的,机构间互信的基于技术的强信任源,从而实现商业模式的颠覆式创新。

    在现阶段,区块链技术从特点上分为两大类,联盟链和公有链。这两类技术各有优劣,应用于不同的商业场景,我们来逐一分析:

    3.1 公有链

    定义:公有链是指任何人都可以自由加入,自由退出,无访问限制(Permissionless)的区块链网络系统。每个互联网用户都可以通过在自己的计算机上安装公有链软件,加入到公有链网络中来,拥有对该网络的所有读写权限,并统一对外提供区块链服务。

    技术特点:

    l 节点数量多:公有链可以支持大规模计算机组网,典型的公有链系统比特币和以太坊的计算机网络都有近百万台计算机组成;

    l 性能低:传统的公有链,如比特币和以太坊,整个系统每秒只能处理20笔以内的交易,性能无法支撑传统的商业应用;近两年发展的区块链3.0技术,通过VRF、VDF、分片等多种技术优化手段,已经可以在保证安全和去中心化的特点下,将性能提升到原有的50-100倍,每秒能处理1000笔以上的交易,接近传统中心化处理系统的能力;

    l 去中心化:公有链网络是一个开放的动态网络,互联网用户可以随意的加入和退出,组成该网络的计算机并不被一个或几个中心控制,是大众所拥有的,所以能最大程度的保证该网络中存储的数据不被篡改和删除。

    由于组成网络的计算机被大众拥有的特点,没有人可以通过任何的技术手段篡改其上的数据,所以公有链网络提供了一个不依赖第三方主观意志的客观信任平台,是一个基于技术的独立的强信任源,这是公有链技术的最大特点。

    3.2 联盟链

    联盟链是由符合某种条件的成员组成的联盟来管理的区块链。它不像公有链那样对全社会开放,只有经过许可的可信节点才能参与组成该联盟链网络,并可以使用该网络的所有读写权限,其它用户仅有部分权限。

    技术特点:

    l 节点数量有限:联盟链系统一般由4到7台计算机组成,其技术能支持的组网计算机数量有限;

    l 性能高:由于组成网络计算机数量少,借助成熟的分布式计算技术,联盟链的计算性能一般都可以达到每秒处理1万笔交易;

    l 半中心化:联盟链系统的计算机一般由组成联盟的多家机构分别提供,用于联盟成员互相间确保对方没有作弊,是可信的;

    由于联盟链系统的计算机是由多家机构提供的,这比由一家机构提供的中心化的系统的可信度有所提升,增加了作弊难度,但如果多家机构进行串谋,还是可以对该联盟链系统中的数据进行修改和删除,所以,联盟链系统本质上依赖的是外界对组成联盟链的多家机构的信任,其不能成为一个独立的强信任源,但适用于对强信任源进行信任传递的场景。

    3.3 应用场景分析

    了解了区块链中公有链和联盟链的技术特点,我们可以分析一下各应用场景的适用技术:

    alt text

    为什么连 BAT 都很难参与到区块链技术的竞争中?

    通过上表我们可以发现,在国家主权级共识和自然垄断性共识场景下,联盟链具有巨大的优势;而在全球共识、竞争性市场共识和行业巨头合作的场景下,公有链具有巨大的优势;做为两个不同的赛道,这两个市场都将是万亿美金级别的市场,都有着广阔的市场前景和发展空间。

    1.1 区块链技术发展趋势

    从我个人的角度看,联盟链和公有链只是区块链技术发展过程中的不同的路径,最终这两项技术将合二为一,各取所长,核心的目标都是能通过技术建立一个客观的第三方强信任源。而他们都需要突破区块链技术由安全、去中心化和性能构成的不可能三角,实现技术的颠覆性、突破性发展,才能更好的支撑业务的变革。

    1.1.1 公有链的发展趋势

    公有链技术做为一个分布式计算、密码学、博弈论等多学科技术综合体,其技术难度非常高。公有链希望构建一个能支撑商业运行的全球性去中心化计算机,但传统的公有链技术还远远未能实现这个目标,主要体现在:

    l 节点集中化:去中心化是公有链最大的特点,网络中独立节点数量越多,网络的去中心化程度就越高,该网络越无法被控制。虽然比特币网络有1百万台左右的矿机组成,但由于其共识设计考虑的不周全(集中在一个机房的机器可以算的更快,具有更高的经济效益),比特币网络的公开IP只有1万个左右,实际上比特币网络可以看作只有1万台计算机组成,这对于支撑一个庞大的万亿美金级别的经济体来说,安全性和去中心化程度是远远不够的。我们需要通过两个方向解决这个问题:从共识角度,消除机器集中带来的经济效益;从网络角度,支持混合网络部署,能自动支持公有云网络、专网、公网、家庭网络的混合部署,最大限度增强网络中独立机器的数量;

    l 性能低下:传统的公有链,如比特币和以太坊,整个系统每秒只能处理20笔以内的交易,性能无法支撑传统的商业应用;需要通过新的创新型的共识设计,在保证安全和去中心化的特点下,将性能提升到原有的50-100倍,每秒至少能处理1000笔以上的交易,接近传统中心化处理系统的能力;

    l 成本高:传统的公有链,由于组成其网络的所有计算机,在一个共识周期内只能同时处理一样的智能合约,导致使用该网络的成本非常高昂,是同等规模云计算成本的100倍以上。为了解决这个问题,需要通过分片等多种技术手段,降低其使用成本到一个合理区间;

    1.1.2 联盟链的发展趋势

    做为以分布式计算技术为基础的联盟链技术,在解决了高性能的前提下,为了拓展其应用场景,下一步的发展趋势一定是提升其组网的节点数量,并解决在节点数量大幅提升后带来的性能、安全性一系列技术挑战,将会面对公有链一样的技术挑战。

    1.2 在中国我们需要什么样的区块链技术

    任何商业的发展和技术的发展都需要符合当地的政策法规和监管要求。中国现行的政策是“无币区块链“,我认为在中国发展的区块链技术应该符合这样的特点:可运行在复杂网络环境下,支持大规模节点,可控可信的高性能许可链。

    l 复杂网络环境:自动支持公有云网络、专网、公网、家庭网络的混合部署;

    l 大规模:理论设计支持100万以上节点组网;

    l 高性能:单链TPS 1000,全网TPS可支持100万;

    l 可控:对全网所有节点状态实时监控,实时跟踪;

    l 可信:所有接入网络的计算机节点,其节点拥有人都需要完成实人身份认证才可以接入;

    l 许可:需要取得许可才能接入网络;

    l 激励:该网络需要有激励,才能让更多人有加入的意愿,与传统的采用数据货币激励的网络不同,应遵循中国监管要求的“无币区块链”,所以该网络的激励不应该采用数字货币的形式激励,而应该建立在DC/EP的基础上,基于DC/EP进行激励;

    1.3 在世界我们需要什么样的区块链技术

    从世界范围看,如果希望建立能支持全球共识的区块链网络,我们需要一个更灵活,更开放,更安全,更动态,更公平的区块链网络:

    l 更开放:该网络是一个全球化部署的网络,才能形成全球性的共识;需要有足够多的独立节点,保证其网络的中立性和可信性,独立节点数量应该至少在百万级别;

    l 更灵活:该网络应该能适应不同国家和地区的法律监管的需要,能够在符合当地监管和法律政策的范围内灵活调整其组网规则;

    l 更安全:KYC的本质是保障链的安全性,在一个国家内可以通过这种方式实现对安全的保障,在跨国的环境下,KYC信息本身就无法跨国流动,所以需要在技术上能像比特币一样,自洽的(博弈论+密码学+分布式技术)实现高安全级别;

    l 更动态:该网络应该可以基于外部环境的变化,包括网络传输环境、节点可信环境、经济体系环境等,动态调节网络能力,使其一直保持在足够稳定、足够健壮、足够安全、足够去中心化的特点;

    l 更公平:考虑到在全球范围内的共识,可能不仅需要支持商业经济生态,还会具备一定的社会属性,该网络的设计需要考虑到多帕累托主体参与以及平衡;

    1.4 区块链未来发展展望

    总的来说,区块链技术的竞争,在经过联盟链和公有链技术的合二为一后,最终将发展为组网能力的竞争。由于区块链技术提供的是一个第三方的强信任源的能力,哪个技术组建的网络中独立节点数量越多,谁就越能提供可靠的强信任源。一个100万独立节点组成的区块链网络提供的不可篡改能力一定高于一个10万独立节点组成的区块链网络。

    而另一个很有意思的特点是,这是一个BAT都很难参与的竞争。如果同样是由100万台计算机构成的区块链网络,一方机器是由互联网用户提供的,一方机器是阿里提供的,则阿里提供的这个区块链网络存在两个致命的劣势:1.100万台机器由互联网用户提供,组网的成本为0,而阿里提供,则阿里需要承担组网的全部高额机器购置成本;2.由阿里提供机器的网络,该网络阿里是具备控制并篡改其上数据内容的能力的,信任该区块链网络,就相当于信任阿里的信用背书,在这种情况下采用阿里的云计算服务似乎是一个更好的选择。

    区块链技术在快速发展,从公有链角度,国际上包括以太坊2.0,Dfinity,Algorand,国内有Conflux和Ultrain团队都在快速接近支持去中心化、安全和高性能的区块链3.0技术目标;从联盟链角度,蚂蚁金服区块链团队和腾讯区块链团队也在快速接近突破大规模网络节点支持这个目标,希望在未来的两年内,区块链技术能有突破性的进展,在商业落地上取得长足的进步,让去中心化的商业生态发展可以初见端倪。

    On the evening of November 29th, the offline meeting of the developers of Ultrain technology "Blockchain technology revealed-zero-knowledge proof and cross-chain in-depth interpretation" was held on time in Hangzhou, and most of the guests on the site were senior developers, Technology company executives. During the event, Wang Husen, the chief cryptologist of Ultrain, and Su Yu, the technical director of the Ultrain, respectively carried out technical sharing and received a warm response from the present guests. The chief digital officer of Ultrain Li Jin also had in-depth exchanges with everyone at the scene!

    alt text

    First,Husen introduced zero-knowledge proof. He said that zero-knowledge proof, as an important privacy protection technology, can play a key role in many scenarios such as subway security inspections, hotel accommodation, bank loans, commercial insurance, and e-commerce shopping.

    Compared to Ethereum, Ultrain's zero-knowledge proof component has the following advantages: 1. The price is more affordable 2. Customizable: Use programmable logic to support arbitrary business logic. In comparison, Ethereum logic needs to be developed, and many basic modules of third-party clients are not supported or unstable. 3. Easy to use: Key generation, certification, verification and other functions can be completed with one click. 4. Template: support for certificate, ERC721, ERC20 templates, which is more convenient than Ethereum and does not require secondary development.

    In the application of blockchain, Husen mentioned: At present Ultrain zero-knowledge proof can play an important role in cross-chain and data privacy, especially for encryption processing of plain text. If you want to transfer anonymous assets, you only need to export the anonymous assets in clear text to prove that they are yours.

    alt text

    Immediately after, Yu introduced Ultrain's resource management and multi-chain management to the guests. In practical scenarios, Ultrain will provide trust computing services for enterprise applications, and then enterprises will deploy DApps to the chain. Any blockchain application on the Ultrain chain will convert user requests into chain requests. Users only need to use DApp applications like ordinary Internet applications, which greatly reduces the threshold for users.

    All Ultrain computing resources are divided into several shares, and each resource purchased by the developer is determined. Ultrain's resource management design makes all resources like sandboxes protect the developer's right to use, and at the same time limits its outward extension, which can effectively prevent EIDOS from congesting EOS.

    Over time, some DApps will require more and more computing resources, while others will become less and less. Free resources are available for free flow, so that resources can be maximized.

    alt text

    Yu said that the key reason why Ultrain can provide enough resources to users and has a more affordable price than Ethereum is its multi-chain parallel expansion model. All accounts will be registered on the main chain, but at the same time the side chain will provide specific services.

    In addition, he also focused on the security issues in a multi-chain architecture: Suppose that a chain has 10,000 miners, and one person wants to do evil, and only needs to control 2/3 miners can control this chain, but if the chain is expanded in parallel Next, this one chain was expanded to 100 chains, the control difficulty was reduced, and the cost of evil was reduced. How to solve the security problem under the premise of parallel expansion? Ultrain uses a random scheduling method, which allows miners to randomly schedule on different chains, which greatly reduces the probability of an attacker controlling a specific side chain.

    Then a problem that comes with it is that if miners are transferred to different chains, they must get the historical data and status of this chain. It is time-consuming to replay blocks in sequence. How to solve it? Ultrain adopts the world state snapshot method. Miners use the world state snapshot to recover to the world state of the specified block, thereby quickly joining the consensus process of the new side chain. In addition, how does Ultrain guarantee the correctness of the world state snapshot? In the main side chain management protocol, the side chain uses the form of oracle to submit the hash value of the world state snapshot of the chain to the main chain system contract for later miners to verify the world state snapshot file.

    Q & A

    alt text

    Question 1: Why is Ultrain cheaper than Ethereum?
    Answer: Ethereum has a low TPS, and it takes a long time to perform an ordinary transaction, so the computing resources are more expensive. In addition, the size of Ethereum is huge, making any small changes requires a large cost, and it is difficult to optimize the shortcomings.

    Question 2: What are the similarities and differences between Ultrain's cross-chain and Boca?
    A: Boca is working hard to achieve on-chain asset, transaction transfer, and shared security, using effective relay chain nodes to provide security for all parachains, and linking current well-known chains (such as Ethereum) through parachain transfer bridges. To make the ecology more prosperous.

    If you have a preliminary understanding of the logic of Poca and Ultrain, you will find at first glance that the two seem to be completely different, but there is actually no essential difference. They just illustrate similar solutions from different perspectives. Ultrain pays more attention to the relationship, showing the relationship of the multi-chain structure at a certain moment; and from the perspective of interaction, Boca shows the interaction relationship between different colors. Parachain is analogous to side chains; validator and fisherman are analogous to mines; collator is analogous to transaction nodes; relay chain is analogous to main chain chain.

    The only difference is the composition of the main chain (relay chain). Ultrain is a group of mines to maintain the operation of the main chain, and Boca is the logic of all relay nodes to run the relay chain to achieve cross-chain communication and other management logic. In fact, the core idea of Boca and Ultrain is very similar, but Ultrain is more pragmatic and hopes to provide computing resources as soon as possible.

    Question 3: What is common between blockchain and AI technology?
    A: Blockchain is not committed to solving artificial intelligence problems, but is more inclined to make data shared and trusted, and to make transactions shared and trusted. Blockchain can be understood as transforming production relations, while artificial intelligence is improving productivity. The combination of the two will enable the commercial landing of many application scenarios.

    As a new generation of commercial blockchain infrastructure, we have always emphasized that leading technology is the cornerstone of our project development, and excellent technology developers are an integral part of our ecology. Ultrain will also continue to host high-quality online and offline technology events, and everyone is welcome to sign up for it!

    11月29日晚,Ultrain 超脑链线下技术开发者见面会「区块链硬核技术揭密——零知识证明及跨链深度解读」于杭州准时举行,现场来宾多为资深开发人士、科技公司高管。活动中,Ultrain 首席密码学家王虎森、技术总监苏羽分别展开了技术分享,并得到了在场嘉宾的热烈反响,Ultrain 首席数字官李津也在现场与大家进行了深度交流!

    alt text

    王虎森首先向大家介绍了零知识证明。他表示,零知识证明作为隐私保护重要技术,可以在地铁安检、酒店住宿、银行贷款、商业保险、电商购物等众多场景起到关键作用。

    相对于以太坊,Ultrain 的零知识证明组件有以下优势:1.价格更加实惠 2.可定制:使用可编程逻辑,支持任意业务逻辑。相比较而言,以太坊逻辑需研发,且第三方客户端很多基本模块不支持或者不稳定。3.易用:可一键完成密钥生成、证明、验证等功能。4.模版化:已支持存证、ERC721、ERC20 模板,相比以太坊更加方便,不需要二次开发。

    在区块链应用上,王虎森提到:目前 Ultrain 零知识证明可在跨链、数据隐私上起到重要作用,尤其是对于对明文的加密处理。想要把匿名资产转移,只需把匿名资产以明文方式导出,就能证明是你的。

    alt text

    紧接着,苏羽向在场嘉宾介绍了 Ultrain 的资源管理和多链管理。在实际场景下,Ultrain 会面向企业应用提供信任计算服务,再由企业部署 DApp 到链上。任何 Ultrain 链上的区块链应用,都会将用户请求转化为链的请求,用户只需像使用普通互联网应用一样使用 DApp 应用,这大大降低了用户的使用门槛。

    Ultrain 的所有计算资源都分成若干份,开发者购买的每一份资源都是确定的。Ultrain 的资源管理设计使所有资源像沙盒一样,保护开发者的使用权利,与此同时也限制了其向外延伸,从而能够有效避免 EIDOS 使 EOS 拥塞的局面发生。

    随着时间的发展,有些 DApp 需要的计算资源将越来越多,有的则将越来越少,空闲资源可供自由流动,从而使得资源得到最大化应用。

    alt text

    Ultrain 计算资源套餐

    苏羽表示,Ultrain 之所以能够提供足够多的资源给用户、并有着比以太坊更加实惠的价格,关键的原因在于其多链平行扩容模型。所有账号将被注册在主链,但与此同时侧链将提供具体服务。

    此外,他还重点阐述了多链架构下的安全问题:假设一条链有 10000 个矿工,一个人想要作恶,只需控制 2/3 个矿工就可以控制这条链,但如果在平行扩容链下,这 1 条链就被扩容成了 100 条链,控制难度降低,作恶成本变低。如何在平行扩容前提下解决安全问题?Ultrain 采取的是随机调度方式,即让矿工在不同链上随机调度,大大降低攻击者控制特定侧链的概率。

    那么随之而来的一个问题是,矿工调动到不同链上,必须得到这条链的历史数据和状态,要依次重放区块非常耗时,如何解决?Ultrain 采取的是世界状态快照方式,矿工利用世界状态快照恢复到指定区块的世界状态,从而快速加入新的侧链的共识过程。此外,Ultrain 又是如何保证世界状态快照的正确性呢?在主侧链管理协议中,侧链采用 oracle 的形式来提交本链世界状态快照的哈希值到主链系统合约,供后面加入的矿工用来校验世界状态快照文件。

    Q & A

    alt text

    问题1:为什么 Ultrain 相比于以太坊费用更加便宜?

    答:以太坊 TPS 较低,进行一个普通交易都需要较长时间,故计算资源更贵。此外,以太坊规模庞大,做任何小型改动都需要付出较大成本,很难对不足之处进行优化。

    问题2:超脑的跨链和波卡有什么异同?

    答:波卡在努力实现链上资产、交易转移及共享安全,使用有效的中继链节点,为所有平行链提供安全性,并通过平行链转接桥链接当下知名的链(如以太坊),从而让生态更繁荣。

    如果大家初步了解过波卡和Ultrain的逻辑,就会发现乍⼀看,两者似乎完全不同,但实际上没有本质区别。它们只是从不同角度阐述了相似的解决方案。Ultrain 更加注重关系,展现多链结构在某一时刻的关系;而波卡从交互的视角,展现了不同⻆色的相互作用关系。平行链(parachain)类⽐于侧链;⻅证节点(validator)和钓⻥人(fisherman)类⽐于矿⼯;收集⼈(collator)类比于交易节点;中继链(relay chain)类比于主链。

    ⼆者唯一不同是主链(中继链)的组成。Ultrain 是由一组矿⼯来维持主链的运⾏,⽽波卡是由所有⻅证节点共同运⾏中继链的逻辑,以实现跨链交易以及其他管理逻辑。其实波卡和 Ultrain 实现的核心思路很像,但 Ultrain 的更务实,希望尽快提供计算资源。

    问题3:区块链与AI技术有什么共通之处?

    答:区块链并不致力于解决人工智能问题,而是更偏向于使数据共享、可信,使交易共享、可信。区块链可以理解为改造生产关系,而人工智能则是提高生产力。两者结合,将能实现众多应用场景的商业落地。

    作为新一代的商业区块链基础设施,我们一直以来都强调,领先的技术是我们项目发展的基石,优秀的技术开发者更是我们生态中不可或缺的一部分。Ultrain 也会持续举办诸如此次的线上线下优质技术活动,欢迎大家届时踊跃报名参加!

    When I first met Xi, I only knew that she was a member of the operation of our Blockchain Charity Project "Wandering Baby" and did not know her well.

    It wasn't until I received information on stray animals from her that I knew that she had always been committed to adopting a large number of dogs, and had run her own animal rescue station.

    And the first 24 dogs launched on the "wandering Baby" platform were all pulled back from the death line and carefully cared for and raised by her.

    Among them is Husky Cici, who was rescued by her from the dog meat car and has since lived a happy and peaceful life:

    alt text

    Alaska Guoguo, which was going to be killed in a slaughterhouse, but was rescued by Xi in time to take care of it, became particularly sticky:

    alt text

    The German shepherd Mumu, who was also rescued from the dog meat car by Xi, took a long time to calm down from panic:

    alt text

    The golden dog Bean that was sold by the original owner at the market for 600 yuan and was taken back by Xi. After a long period of depression, it have finally been able to open up to humanity and live in harmony now:

    alt text

    White who was abandoned in the hospital and obviously has reached the age of "old man", but he is so strong now:

    alt text

    There is also a small Chinese rural dog Apple who was cruelly abandoned by the original owner in a plastic bag near the trash due to a disabled eye, but was rescued by Xi, and since then he lived strongly:

    alt text

    In addition, the most impressive thing for me is the Labrador dog Jiao Jiao. Due to severe pneumonia, the original owner left her in the pet hospital, and even when Xi came and wanted to take Jiao Jiao to the hospital for treatment, the original owner was still reluctant to settle the original hospitalization fee. In the end, Xi paid all the costs, transferred Jiao Jiao with pneumonia in her body to the point where she had severe stagnant water, and transferred to hospital for treatment for a long time. She spent a lot of time, energy, and money to finally recover Jiao Jiao. Life is not a child's play. When you want a pet to accompany you, please be prepared to be responsible for its life.

    alt text

    Whenever there are several extreme cases in society, people always say: I don’t know that human nature can be so bad. Faced with the staff of an animal rescue station like Xi, we just want to say one thing: human nature can be so beautiful.

    Life is not high or low, and the variety and physical conditions are by no means a measure of the right to life.

    We often think that if there are more loving people in the world, such as Xi, the status of stray animals will eventually improve.

    If you also want to participate in the rescue of stray animals, if you also want to give a love to stray animals, and let your donation record be recorded on the chain forever and cannot be tampered with, please scan the following small program. Each of your love and support will be a force for stray babies to thrive.

    alt text

    Ultrain will also continue to use blockchain technology to contribute to philanthropy. As of now, in pet assistance, we are only cooperating with "Where Dogs Go", the largest pet community in China. The Pet Center contacted us to let more dogs get the love of people.

    If this world can be made better, then we must not humiliate our mission.

    小编最初接触汐子时,只知道她是配合我们区块链慈善项目「流浪宝贝」运营的一员,对她不甚了解。

    直至从她手中接过流浪动物们的资料,我才知道:她一直以来都致力于在京城自费收养大量的狗狗们,并自营了流浪动物救助站。

    而本期「流浪宝贝」小程序上线的第一批 24 只狗狗,无一不是被她从死亡线上拉回、并用心照顾与抚养。

    这其中,有被汐子从狗肉车上救回、并从此过上了幸福祥和生活的哈士奇 Cici:

    替代文字

    有下一秒就将在屠宰场沦为锅中肉、却又及时被汐子救回悉心照料,从此变得特别黏人的阿拉斯加大果:

    替代文字

    有同样被汐子从狗肉车上救回、花费了很长时间才从惊恐中缓过神的德国牧羊犬木木:

    替代文字

    有被原主人以600块在集市上卖出、被汐子接回后仍郁郁寡欢许久,至今终于能对人类敞开心扉和谐共处的金毛毛豆:

    替代文字

    有曾被遗弃在医院、明明已经到了“老爷子”的年龄,力气大得却还像正值壮年的大白熊大白:

    替代文字

    还有因一只眼睛残疾被原主人残忍遗弃在垃圾桶旁塑料袋里等死、却被路过的汐子救出,并从此乖巧努力又坚强地活着的中华田园犬小爱:

    替代文字

    除此之外,最让小编印象深刻的还是一只叫娇娇的拉布拉多。它因患有重度肺炎,被原主人丢弃在宠物医院,甚至于当闻讯赶来的汐子表示想带娇娇转院治疗时,原主人仍不愿结清原住院费。最后,汐子支付了所有费用,带着体内肺炎已经严重到积水程度的娇娇转院治疗并悉心照料了很长一段时间,花费了大量时间精力财力,终于让娇娇得以痊愈。性命不是儿戏,当你想要养一只宠物得以陪伴,也请做好要为它的生命负责的准备。

    替代文字

    ... ...

    每当社会上发生几起极端案件,人们总会说:我竟不知人性可以坏到如此地步。而面对像汐子这样动物救助站的工作人员,我们只想说一句:原来人性也可以是如此的美好。

    生命没有高低贵贱,品种及身体条件也绝不是一把有关生存权利的度量尺。

    我们常想,如果这个世界上能多一些诸如汐子这样的爱心人士,流浪动物的现状也终将得以改善。

    如果你也想参与到流浪动物救助中来,如果你也想要为流浪动物献上一份爱心,并且让自己的捐赠记录从此记载在链上永续留存不可篡改,欢迎点击以下小程序。你的每一份爱心助养,都必将成为流浪宝贝们得以茁壮成长的力量。

    Ultrain 也将持续用区块链技术为慈善事业尽心尽力。截至目前,在宠物救助上,我们仅在与中国第一大宠物社区「狗狗去哪儿」合作(汐子救助的以上24只狗狗均属于其平台照料范围),也欢迎全国各地需要帮助的宠物中心与我们联系,让更多狗狗得到社会各界人士的爱心。

    倘若能让这个世界就此变得更加美好,那么想必,我们也不辱使命。

    Is EOS smashed?

    I have to say that EIDOS is a very smart design, it kicked the BM's ass.

    alt text

    Why is it that it kicked BM's ass instead of EOS's ass? Because strictly speaking, EOS as a public chain, an infrastructure, a network consisting of direct connections from super nodes, has always been running well, effectively providing blockchain services.

    According to EOS New York, the “EOS main net is almost paralyzed” by the major media is actually an exaggeration or even a misunderstanding. EOS has never been paralyzed, just you can't afford it. According to the data from https://eosflare.io/, the peak value of TPS is only 910, and there is room for EOS design capacity.

    The problem is not in the network performance of EOS, but in the design of BM. The original resource strategy of the chain is not designed to serve the application better, but for marketing. Higher turnouts (community management), completely free use, etc., these gimmicks are indeed eye-catching. Based on such a starting point, there is a strategy for allocating computing resources based on the amount of mortgage. The following questions are all from this.

    (1) Resource instability

    CPU, NET is obtained by mortgage EOS, it is unstable. Simply put, when more people mortgage more EOS to get the CPU, NET, your resources are diluted. For example, let's assume that there are 3 seconds to perform the transfer. If you mortgage 100 EOS to get CPU resources, I mortgaged 200 EOS to get CPU resources. I am 2:1 for you, then the system will Assign 2 seconds of CPU resources to help me do things, 1 second of CPU resources to help you do things; then when extremes happen, I mortgage a lot of EOS to buy the CPU, let's say I am 1000:1 for you, then you only have very Less CPU is executed. At this time, you may use more EOS to buy the CPU. When everyone does this, the CPU price becomes huge, and everyone is in a vicious circle. It is possible that a CPU with 0.1 EOS collateral can complete a transfer, and in a competitive environment it will become possible that 100 EOS collaterals are not enough to complete a transfer.

    (2) The cost of learning for ordinary users has increased sharply

    Originally, the blockchain threshold has been very high, and this design of BM has increased the difficulty. DAPP is more difficult to promote and can only compete among stock users. As a normal user, such as Plaza Aunt, she not only has to understand the public key, private key, but also CPU, NET, RAM. Even if she got the CPU hard, such as 10 ms. This is awkward, what concept can be said that ordinary people can hardly understand. What is even more ridiculous is that it is actually changing. It can still be used for 10 ms today, and it may become 0.01 ms tomorrow. Even ordinary transfers can't be done. How do you let ordinary people use it?

    (3) Is EOSREX serving small and medium-sized retail investors?

    Due to the large amount of EOS being mortgaged, it is difficult for small retail investors to get computing resources to use DAPP, which seriously affects the promotion of DAPP. At this time, BM did not reflect on the resource allocation strategy, but introduced another ambitious design EOSREX, which was intended to allow large customers to lend EOS to retail investors to obtain computing resources, and then use DAPP. But how can the interest rate of the big family be better than the rate of return? Not some small and medium-sized people are eating this chicken rib. The chicken ribs are chicken ribs, there is always some meat. However, the product itself has a financial design flaw that exposes the risk of maturity mismatch to users who purchase REX. That is, when you want to get it back, REX doesn't necessarily sell it. It is hard to imagine that big families will participate.

    Of course, EOSREX as a DeFi product is not a big deal. It just wants to use it to patch the resource strategy. It is inevitable that it will be wishful thinking.

    (4) There is no primary or secondary business

    The core functions are not prioritized with common applications, and stability is worrying. Specifically, the case of EIDOS is that when a nuclear bomb-level MLM application like EIDOS goes online, the core functions are instantaneous. But technically, EOS is not awkward, but you are too poor to afford. Looking at the people's exchanges and increasing the CPU mortgage, you can guarantee that the transfer business is basically unaffected. One side is said to be free, and it is expensive to use. Is it very split? BM is a good interpretation: free is the most expensive.

    (5) "Garbage" DAPP's paradise

    Any DAPP can be deployed to the chain at a low cost, but it can act as a catalyst, causing an infinite amplification of the chain, exposing the entire chain and other applications on the chain to risk.

    Can Ultrain solve this problem?

    Before answering this question, we must first declare that the above analysis of the EOS problem is only for the singularity of BM resource management. EOS as an open source project, technically, we still appreciate it.

    The reasons for EOS congestion have been resolved from multiple perspectives. The fundamental problem is the resource design of the EOS chain, not the throughput. Ultrain avoided these issues from the beginning of the design.

    (1)Ultrain's multi-chains architecture mode

    alt text

    Ultrain adopts a multi-chains architecture mode which is the main and side chains. The main chain is not deploying DAPP, focusing on the transfer of core assets UGAS and the management of side chains.

    DAPP is deployed on the side chain, so even if you want to deploy an application such as EIDOS to Ultrain, it will not affect core functions such as transfer.

    (2) Innovative resource management allocation model

    Although the application of the nuclear bomb level does not affect the core function of the main chain, does it have any effect on the side chain it deploys?
    The answer is that the impact is small.

    Ultrain is a service provider that distributes resources to DAPP in a pre-sale manner. The capacity of any DAPP is limited by the amount of resources purchased. This pre-sale resource is stable and inelastic. It is a strict sandbox that locks DAPP inside. Any DAPP can only affect side chains within this range.

    This time, EIDOS actually only costs a very small amount of cost to deploy DAPP, as small as can be ignored, really empty gloves white wolf. What really destroyed EOS was the speculators of countless wool, who took up a lot of resources and launched a DDOS attack on EOS.

    This is not the case with Ultrain, which is completely limited by the resources it purchases. If its business geometry increases, but does not replenish the resource package in time, then the DAPP itself will be congested, downtime, and will not affect other applications of this side chain.

    (3) How does the resource flow?

    Careful people may have noticed that Ultrain's several technical weekly reports have repeatedly mentioned the resource market, which is designed for resource circulation. Assuming that EIDOS wants to expand, it must enter the market to purchase packages from other DAPP service providers and use real money to compensate other affected DAPP service providers.

    Regarding the resource market, we will give you a more detailed introduction after the function is launched.

    EOS 瘫痪了吗?

    不得不说,EIDOS 是个很聪明的设计,它狠狠地踢了 BM 的屁股。

    alt text

    为什么说是踢了 BM 的屁股,而不是EOS的屁股呢?因为严格来说 EOS 作为公链、一个基础设施、一个由超级节点直连组成的网络,一直都运行良好,有效地提供了区块链的服务。

    EOS New York 表示,各大媒体充斥的“ EOS 主网近乎瘫痪”,其实是一种夸大甚至是误读。EOS 从来没有瘫痪,只是你用不起而已。根据 https://eosflare.io/ 的数据,TPS 的峰值也只是到了 910,根据 EOS 的设计容量还有余地。

    问题并不出在 EOS 的网络性能,而是 BM 奇技淫巧的设计。链上资源策略的设计初衷不是更好的服务于应用,而是为了营销。更高的投票率(社区治理)、完全免费的使用等等,这些噱头确实能够吸引眼球。基于这样的出发点才有了根据抵押量来分配计算资源的策略。以下几个问题皆源于此。

    (1)资源不稳定性

    CPU,NET 是靠抵押 EOS 获得的,它是不稳定的。简单说就是当更多人抵押更多 EOS 来获得 CPU,NET 后,你的资源就被稀释了。举个例子,假设有 3 秒的时间用来执行转账,如果你抵押了 100 EOS 用来获得 CPU 资源,我抵押了 200 EOS 用来获得 CPU 资源,我对你是 2:1,那系统就会分配 2 秒 CPU 资源帮我做事,1 秒 CPU 资源来帮你做事;然后当极端情况发生时,我抵押了大量的 EOS 来购买 CPU,比方说我对你是 1000:1, 那你就只有很少的 CPU 来执行了。这个时候你可能就会用更多的 EOS 去购买 CPU,当所有人都这么做的时候,CPU 价格变得巨高,大家陷入了恶性循环中。本来可能 0.1 个 EOS 抵押获得的 CPU 就能完成一笔转账,在竞争环境下会变成可能 100 个 EOS 抵押获得的 CPU 都不够完成一笔转账。

    (2)普通用户学习成本陡增

    本来区块链门槛已经很高了,BM 的这个设计更是增加了难度。DAPP 更加难以推广,只能在存量用户里面争夺。作为一个普通用户,比如广场大妈,她不仅要去理解公钥、私钥,还要知道CPU、NET、RAM。即使她千辛万苦拿到了 CPU,比如10 ms 。这是个啥,什么概念,可以说普通人基本无法理解。更让人匪夷所思的是它居然在变,今天还能用 10 ms,明天就可能变成 0.01 ms。连笔普通的转账都做不了。你让普通人怎么使用呢?

    (3)EOSREX 是服务中小散户的吗?

    由于大量 EOS 被抵押,导致小散户很难拿到计算资源去使用 DAPP,严重影响了 DAPP 的推广。这个时候 BM 并不是反思资源分配策略,而是推出了另一个宏大设计 EOSREX,本意是想让大户出借 EOS 给散户去获得计算资源,进而可以使用 DAPP。可是那聊胜于无的收益率,怎么能引起大户的兴趣?还不是一些中小散在吃这根鸡肋。鸡肋就鸡肋吧,总还有点肉。可是这个产品本身存在金融设计漏洞,将期限错配的风险完全暴露给购买 REX 的用户。也就是你想取回的时候,REX 不一定卖的出。很难想象大户会参与。

    当然,EOSREX 作为一种 DeFi 产品,本身并无可厚非,只是想用它来给资源策略打补丁,难免一厢情愿了。

    (4)业务没有主次

    核心功能,跟普通应用没有区分优先级,稳定性堪忧。具体到 EIDOS 这个 case,就是当类似 EIDOS 这种核弹级传销应用上线后,核心功能瞬间瘫痪。但是技术上讲,EOS 没有瘫痪,只是你太穷了,用不起。看看人家交易所,大量增加 CPU 抵押后,可以保证转账业务基本不受影响。一边号称免费,一边又贵的用不起。是不是很分裂。BM 很好的诠释了:免费的才是最贵的。

    (5)“垃圾” DAPP 的乐园

    任何 DAPP 都可以很低成本部署到链上,却可以起到催化剂的作用,对链造成无限放大的影响,将整条链以及链上其他的应用都暴露在风险之中。

    Ultrain 能解决这个问题吗?

    在回答这个问题之前,先要声明一点,以上对 EOS 问题的剖析,仅仅针对 BM 资源管理的奇技淫巧。EOS 作为一个开源项目,从技术上讲,我们还是非常欣赏的。

    上面已经从多个角度解析了 EOS 拥塞的原因,它的根本问题在于 EOS 链的资源设计,而不是吞吐量。而 Ultrain 在设计之初就从架构设计上避免了这些问题。

    (1)Ultrain 的多链架构模式

    alt text

    Ultrain 采用了主侧链的多链架构模式,主链是不部署 DAPP 的,专注于核心资产 UGAS 的转账和侧链的管理。

    DAPP 是部署在侧链上,所以即便想 EIDOS 这样的应用部署到 Ultrain 上,也不会影响转账等核心功能。

    (2)创新的资源管理分配模型

    虽然核弹级的应用不会影响主链的核心功能,那么对它部署的侧链有没有影响呢?

    答案是,影响不大。

    Ultrain 是通过预售的方式将资源分配给 DAPP 的服务商。任何 DAPP 的容量都受限于购买资源的数量。这个预售的资源是稳定的,并且无弹性的。它是一个严格的沙盒,将 DAPP 关在里面。任何 DAPP 只能在这个范围内影响侧链。

    这次 EIDOS 其实只消耗了极少的成本来部署 DAPP,少到可以忽略,真的空手套白狼。真正摧毁 EOS 的是无数的薅羊毛的投机者,是他们占用了大量资源,对 EOS 发起 DDOS 攻击。

    而在 Ultrain 上面这种情况是不会发生的,DAPP 的业务规模完全受限于它购买的资源。如果它的业务几何级数增长,但是没有及时补充资源套餐,那么这个 DAPP 自身会拥塞,宕机,不会影响这条侧链的其他应用。

    (3)资源如何流转?

    细心的同学可能注意到,最近 Ultrain 的几期技术周报多次提及资源市场,就是为了资源流转而设计的。假设 EIDOS 想扩容,那么它必须进入市场从其他 DAPP 服务商那里购买套餐,用真金白银补偿受影响的其他 DAPP 服务商。

    关于资源市场,功能上线后,我们会给大家更详细的介绍。
