爭(zhēng)議伴隨區(qū)塊鏈成長(zhǎng)。 </div> <div id="2bbnk7a" class="m-txt"><div class="cat7nzj" id="multi-text" class="f-cb"><p>若從2008年中本聰發(fā)明比特幣算起，區(qū)塊鏈技術(shù)走進(jìn)大眾的視野已經(jīng)10年。這個(gè)自誕生之日起就不斷自我革新的物種，始終顛覆著社會(huì)的認(rèn)知，也誕生過(guò)一個(gè)個(gè)造富神話。</p> <p>與此同時(shí)，爭(zhēng)議與討論也伴隨著區(qū)塊鏈的成長(zhǎng)，人們對(duì)這項(xiàng)新技術(shù)創(chuàng)新的看法依然大相徑庭，莫衷一是。</p> <p>“在過(guò)去的一段時(shí)間內(nèi)，有一些ICO，它們的機(jī)制、組織非?；靵y，到最后演變成了一個(gè)‘零和博弈’。我們所說(shuō)的區(qū)塊鏈的目的，是使得世界變得更加開(kāi)放、更加透明，而不是去消耗資源。”2018年9月11日，在萬(wàn)向區(qū)塊鏈實(shí)驗(yàn)室主辦、上海市虹口區(qū)人民政府指導(dǎo)的2018上海區(qū)塊鏈國(guó)際周-第四屆區(qū)塊鏈全球峰會(huì)上，以太坊創(chuàng)始人Vitalik Buterin談道。</p> <p>對(duì)此，中國(guó)銀行前行長(zhǎng)李禮輝表示認(rèn)同，他認(rèn)為區(qū)塊鏈整體上并不成熟，區(qū)塊鏈技術(shù)規(guī)?；瘧?yīng)用還處于研發(fā)和實(shí)驗(yàn)狀態(tài)，需要更扎實(shí)的技術(shù)探索和制度研究。</p> <p>“區(qū)塊鏈業(yè)者需要聆聽(tīng)、思考、交流、討論，更需要探索、實(shí)踐、創(chuàng)新、變革。”李禮輝說(shuō)。</p> <p><strong>進(jìn)步與藩籬</strong></p> <p>李禮輝認(rèn)為，包括區(qū)塊鏈在內(nèi)的新技術(shù)的成功，需要滿足4個(gè)基本要素：更高的效率、更低的成本、更具商業(yè)價(jià)值的經(jīng)濟(jì)規(guī)模和更被認(rèn)可的可靠性與安全性。</p> <p>在分布式、多中心、有中介的聯(lián)盟鏈架構(gòu)下，李禮輝認(rèn)為區(qū)塊鏈實(shí)體應(yīng)用有兩個(gè)方面值得重視：一是建立多緯度直接交互架構(gòu)，在參與方多、高幅度性金融交易的場(chǎng)景中實(shí)現(xiàn)眾多參與方之間零距離、零時(shí)差的交通，可以做到協(xié)同治理、精簡(jiǎn)流程、提高效率、節(jié)約成本；二是建立可信數(shù)據(jù)登記與證實(shí)平臺(tái)。</p> <p>前者有例如中國(guó)郵儲(chǔ)銀行的資產(chǎn)托管系統(tǒng)、微眾銀行的聯(lián)合貸款管理及對(duì)賬系統(tǒng)、平安的金融一賬通等；后者則有中鈔絡(luò)譜區(qū)塊鏈開(kāi)放平臺(tái)、螞蟻區(qū)塊鏈可信數(shù)據(jù)存證平臺(tái)等。</p> <p>而分布式、去中心、自組織的公有鏈架構(gòu)也出現(xiàn)了越來(lái)越多的商業(yè)應(yīng)用。</p> <p>“有一批技術(shù)專家和創(chuàng)業(yè)者正在研發(fā)基于公有鏈架構(gòu)的區(qū)塊鏈技術(shù)應(yīng)用，試圖打造規(guī)?；墟溒脚_(tái)，形成點(diǎn)對(duì)點(diǎn)、去中心的分布式商業(yè)模式。有人把它稱之為‘DAPP’（Decentralized Application，分布式應(yīng)用），DAPP的應(yīng)用不需要太高的交易速度，但是足以形成集群效應(yīng)。假如一個(gè)公有鏈有1億個(gè)DAPP，每個(gè)DAPP能創(chuàng)造10億美元的價(jià)值，這個(gè)公有鏈就有10億美元的價(jià)值。” 李禮輝說(shuō)。</p> <p>盡管如此，李禮輝仍然認(rèn)為區(qū)塊鏈技術(shù)規(guī)?；纳逃眠€需要突破一系列的技術(shù)與制度的瓶頸。比如，隱私保護(hù)、監(jiān)督機(jī)制、智能合約技術(shù)、私鑰保護(hù)技術(shù)等方面仍然需要探討、考察以及進(jìn)化。“規(guī)?；€上自組織的經(jīng)濟(jì)業(yè)態(tài)如何實(shí)現(xiàn)？數(shù)學(xué)算法能否成功地替代中心、中介、法律、執(zhí)法者？算力優(yōu)勢(shì)會(huì)不會(huì)構(gòu)成壟斷妨礙公平？地下灰/黑色交易能否得到有效地管控？”</p> <p>在比特大陸創(chuàng)始人兼首席執(zhí)行官吳忌寒看來(lái)，區(qū)塊鏈的隱私性與安全性是存在矛盾的。“最早的UTXO（Unspent Transaction Output，未被花費(fèi)的交易輸出）模型和賬戶模型，在系統(tǒng)安全性方面有明顯的優(yōu)勢(shì)，因?yàn)樗械臄?shù)據(jù)都是記錄在鏈上，所有人都可以對(duì)腳本的執(zhí)行過(guò)程進(jìn)行閱讀觀察，所以它的安全性非常強(qiáng)。但同時(shí)它的隱私性是不夠的，因?yàn)樗械逆溕辖灰锥伎梢员挥^察到。比如，有一些地下網(wǎng)絡(luò)市場(chǎng)，他們用比特幣作為結(jié)算貨幣，這些交易的流向容易被追蹤。”</p> <p>另一方面，區(qū)塊鏈本身的技術(shù)中立性也帶來(lái)了挑戰(zhàn)。吳忌寒認(rèn)為，區(qū)塊鏈未來(lái)十年的發(fā)展，最為主要的應(yīng)用還是在金融場(chǎng)景，這當(dāng)中會(huì)有非常復(fù)雜的立法與監(jiān)管的問(wèn)題需要研究。“區(qū)塊鏈技術(shù)的中立性是很難打破的，因?yàn)閰^(qū)塊鏈?zhǔn)亲杂傻?，有一個(gè)受到監(jiān)管的區(qū)塊鏈，會(huì)有一個(gè)繼續(xù)保持技術(shù)中立性區(qū)塊鏈技術(shù)的出現(xiàn)，來(lái)替代管制區(qū)塊鏈。立法者要基于中立的區(qū)塊鏈去發(fā)展自己的監(jiān)管技術(shù)。”</p> <p>以太坊創(chuàng)始人Vitalik Buterin在會(huì)上也表達(dá)了類似的觀點(diǎn)，他認(rèn)為區(qū)塊鏈機(jī)制會(huì)面臨四大挑戰(zhàn)：礦工或驗(yàn)證者的操縱、隱私的保護(hù)、反Sybil攻擊、共謀的可能性。</p> <p>可以看到的是，區(qū)塊鏈技術(shù)在帶來(lái)更加透明數(shù)據(jù)的同時(shí)，也帶來(lái)了公平、倫理、技術(shù)等多方面的制約因素，正因如此，區(qū)塊鏈要真正實(shí)現(xiàn)大規(guī)模、大效率、高可靠性的商業(yè)化應(yīng)用還有很長(zhǎng)的路要走。用李禮輝的話說(shuō)，通向未來(lái)的道路依然云遮霧罩、山高水遠(yuǎn)，重點(diǎn)是如何進(jìn)一步突破區(qū)塊鏈底層應(yīng)用的關(guān)鍵技術(shù)，如何加快區(qū)塊鏈技術(shù)標(biāo)準(zhǔn)化建設(shè)和區(qū)塊鏈金融監(jiān)管制度的建設(shè)，加快區(qū)塊鏈技術(shù)人才培養(yǎng)和隊(duì)伍建設(shè)。</p> <p><strong>呼喚國(guó)際標(biāo)準(zhǔn)</strong></p> <p>ISO TC/307主席Craig Dunn表示，如今的區(qū)塊鏈正在慢慢被主流社會(huì)接受，越來(lái)越多的相關(guān)方都開(kāi)始了解區(qū)塊鏈、投資區(qū)塊鏈、利用區(qū)塊鏈，同時(shí)也有很多人持懷疑的態(tài)度，他們置疑區(qū)塊鏈的潛力——這個(gè)時(shí)候就需要對(duì)發(fā)展賦予真正的含義，即國(guó)際標(biāo)準(zhǔn)。</p> <p>“標(biāo)準(zhǔn)不是為了限制、阻礙創(chuàng)新，是為了刺激和鼓勵(lì)創(chuàng)新，更重要的是為例降低創(chuàng)新的成本，特別是新技術(shù)創(chuàng)新的成本。”Craig說(shuō)，“開(kāi)發(fā)技術(shù)的人應(yīng)該鼓勵(lì)最佳實(shí)踐標(biāo)準(zhǔn)和行為準(zhǔn)則，一切的核心是社會(huì)的利益，這也是國(guó)際標(biāo)準(zhǔn)的意義所在。”</p> <p>Craig以國(guó)際手機(jī)標(biāo)準(zhǔn)為例，正是由于該標(biāo)準(zhǔn)的出臺(tái)，消費(fèi)者可以在不同的國(guó)家用同一臺(tái)手機(jī)，通信運(yùn)營(yíng)商可以節(jié)省大量投資并減少用戶轉(zhuǎn)化成本。而從3G、4G到5G，標(biāo)準(zhǔn)的制定也有利于快速部署技術(shù)。他說(shuō)，“在環(huán)境中，技術(shù)的應(yīng)用是不一致的，但是技術(shù)的標(biāo)準(zhǔn)仍然是非常有效的，這就體現(xiàn)出技術(shù)標(biāo)準(zhǔn)以及創(chuàng)新的有效性。”</p> <p>據(jù)介紹，在國(guó)際標(biāo)準(zhǔn)委員會(huì)中，有165個(gè)會(huì)員國(guó)參與國(guó)際標(biāo)準(zhǔn)的制定過(guò)程，有50個(gè)國(guó)家（包括中國(guó)）參與區(qū)塊鏈標(biāo)準(zhǔn)的制定過(guò)程。而技術(shù)委員會(huì)TC 307存在的目的就是希望能夠滿足區(qū)塊鏈領(lǐng)域標(biāo)準(zhǔn)化不斷增長(zhǎng)的需求，以提供國(guó)際共識(shí)方式來(lái)提升該技術(shù)的安全性、隱私性、可擴(kuò)展性、互操作性，鼓勵(lì)這一技術(shù)的廣泛普及。</p> <p>對(duì)此，Craig談到，標(biāo)準(zhǔn)可以由政府、中央監(jiān)管機(jī)構(gòu)來(lái)制定，可以通過(guò)共識(shí)來(lái)制定，也可以通過(guò)事實(shí)來(lái)制定，這三種類型的標(biāo)準(zhǔn)制定都各有優(yōu)劣。</p> <p>“有些人會(huì)說(shuō)現(xiàn)在區(qū)塊鏈領(lǐng)域制定標(biāo)準(zhǔn)還為時(shí)過(guò)早，因?yàn)檫@項(xiàng)技術(shù)還不成熟。過(guò)早的制定標(biāo)準(zhǔn)會(huì)有風(fēng)險(xiǎn)，沒(méi)有辦法適應(yīng)未來(lái)的發(fā)展——分布式區(qū)塊技術(shù)確實(shí)存在這樣的風(fēng)險(xiǎn)；如果讓市場(chǎng)所形成的事實(shí)標(biāo)準(zhǔn)來(lái)決定的話，并不是非常公平，而是由公司、機(jī)構(gòu)來(lái)指導(dǎo)制定的，并且不一定永遠(yuǎn)都是最佳標(biāo)準(zhǔn)。”基于此，Craig認(rèn)為基于共識(shí)的制定方法是區(qū)塊鏈國(guó)際標(biāo)準(zhǔn)制定的最優(yōu)解。</p>
