随着新基建领域的确立，区块链技术正以前所未有的速度蓬勃发展，并已成为2020年度备受瞩目的新兴主流技术关键词。然而，提及区块链，公众普遍将其与比特币、以太坊等加密货币挂钩。
With the establishment of new infrastructure areas, block chain technology is flourishing at an unprecedented pace and has become a prominent new mainstream technology key word for 2020. However, with reference to block chains, the public generally links them to encrypted currency such as Bitcoin and Taiku.
据Cointelegraph报道，数字资产情报公司CipherTrace发布的报告显示，仅在2020年前五个月内，犯罪分子利用新冠疫情肆虐之际，通过诈骗等多种途径吸收了近14亿美元的非法资金。
According to Cointeelegraph, a report issued by the digital asset intelligence company CipherTrace showed that nearly $1.4 billion of illicit money had been absorbed by criminals through various means, including fraud, only during the first five months of 2020, when the epidemic was taking advantage of.
这短短五个月里，14亿美元的巨大金额令人瞠目，反映出加密货币市场的资产保护措施尚存严重不足。今年六月初，PIEXGO、UEX、LMEX、FUBT等诸多交易平台相继被质疑涉嫌“跑路”，尽管各平台纷纷澄清仅为黑客攻击导致提现暂停，但仅仅依靠声明难以消除消费者的疑虑。
In just five months, 1.4 billion dollars is a staggering amount, reflecting a serious shortfall in asset protection in the crypto-money market. Many trading platforms, such as PIEXGO, UEX, LMEX, and FUBT, were subsequently questioned as being suspected of “runaways” at the beginning of June.
此外，加密货币被盗及交易所遭受攻击的现象频发，且其与洗钱等违法行为密切相关，如臭名昭著的丝绸之路案例所示。加密货币的匿名性加大了资产追踪的难度，虽然这种特性在一定程度上保护了用户的隐私安全，但也给不法分子提供了可乘之机。
In addition, the theft of encrypted money and the frequent attacks on exchanges are closely linked to offences such as money-laundering, as demonstrated by the notorious Silk Road case. The anonymity of encrypted money makes asset tracing more difficult, although it provides some protection for the privacy of users, but also offers opportunities for outlaws.
同时，加密货币的公开性也是一个显著特征——所有交易都会记录在区块链上，任何人都可通过区块链浏览器等工具查询交易信息。因此，在交易所遭遇暂停充值或提现、受到攻击等情况时，除了官方声明之外，观察交易所地址余额的变化也可以成为验证事实的一种方式。
At the same time, the openness of encrypted money is also a notable feature — all transactions are recorded on the block chain, and anyone can search for transaction information through tools such as block-chain browsers. Thus, in cases where the exchange is subject to suspensions or withdrawals, attacks, etc., observing changes in the stock balance of the exchange, in addition to official statements, can also be used as a means of establishing the facts.
区块链溯源技术与比特币浏览器的应用区块链浏览器堪称区块链基础设施中的基石。每个区块链主网启动后，首要任务即是构建浏览器，以便外界直观获取链上交易、地址等信息。它不仅是查询链上信息和提供投资决策依据的工具，在诸如反洗钱这样的案件追踪中，同样发挥着重要作用。
A block-chain browser is a cornerstone of the block-chain infrastructure. After each block-chain main network is activated, the first task is to build a browser so that the outside world can visualize transactions, addresses, etc. on the chain. It is not only a tool for searching information on the chain and providing the basis for investment decisions, but it also plays an important role in tracking cases such as anti-money-laundering.
丝绸之路案的破获就充分体现了区块链浏览器的关键作用。曾任联邦检察官的Kathryn Haun指出，犯罪分子利用比特币进行交易，而正是依托于比特币的底层技术——区块链技术，FBI得以完成刑事调查。
The discovery of the Silk Road case amply reflects the key role of block-chain browsers. Kathryn Haun, a former federal prosecutor, pointed out that criminals used bitcoin for trading, and that it was the bottom technology of bitcoin – block-chain technology – that enabled the FBI to complete its criminal investigation.
Haun在接受采访时表示，政府部门及相关执法机构如国税局、FBI和国土安全调查局等，在调查过程中借助区块链浏览器，运用链上数据追踪技术找寻到了有力证据。
In an interview, Haun stated that government departments and relevant law enforcement agencies, such as the IRS, the FBI and the Homeland Security Investigation Agency, had relied on block-link browsers in the course of their investigations to find strong evidence using data tracking techniques on the chain.
区块链浏览器无疑是实现溯源技术不可或缺的重要工具。无论是实时追踪单一交易，还是追溯涉及成千上万笔交易的情况，都能发挥作用。例如，在比特币浏览器中输入交易产生的唯一交易ID（txid, transaction ID），就能清晰掌握资金流向。
A block-chain browser is undoubtedly an essential tool to achieve traceability technology. Either a single transaction is tracked in real time or thousands of transactions are traced back to work. For example, entering the only transaction ID (txid, transaction ID) generated by the transaction in a bitcoin browser provides a clear picture of the flow of funds.
区块链FBI再度升级：OKLink区块链浏览器推出地址标签功能地址标签，顾名思义，就是在发送/接收加密货币的虚拟地址上附加标签，从而更快识别不同虚拟地址背后的主体身份，追踪各个地址间资金流动轨迹。
Address labels, by definition, add labels to virtual addresses where encrypted currency is sent/received, thereby faster identifying the subject behind different virtual addresses and tracking the movement of funds between addresses.
目前市面上的区块链浏览器很少收录地址标签。然而，6月10日，全球首家区块链大数据上市企业欧科云链推出的OKLink区块链浏览器宣布，已在全球范围内为其添加了三千万个主流交易所地址标签。用户现在可以在OKLink区块链浏览器的交易详情和地址详情等页面查看已收录的地址标签。
Currently, block chain browsers on the market rarely include address labels. On June 10, however, the OkLink block web browser, launched by the world’s first block chain big data company, Ocowin, announced that 30 million mainstream exchange address labels had been added to it globally. Users can now view the accepted address tags on pages such as transaction details and address details of the OKLink block chain browser.
欧科云链OKLink产品副总裁张超表示，这只是第一步，OKLink将交叉对比交易关系，进一步分析标记出更多交易所、矿池等地址标签，致力于构建一个自动追踪的智能分析工具，以便用户利用这些地址标签查询潜在的风险交易并标记异常地址。
Mr. Zhang, Vice-President of the OkLink product, Ocowin Chain, said that this was only a first step, and that OKLink would cross-check trading relationships, further analyse the identification of additional address labels, such as exchanges, pits, etc., and work on the construction of an automated tracking smart analysis tool to enable users to use these address labels to search for potential risk transactions and mark unusual addresses.
数据是区块链网络的根本。欧科集团创始人徐明星曾在多个公开场合强调，区块链技术的本质是一个分布式的、不可逆的数据库。
Data are fundamental to the network of block chains. The founder of the EUCO Group, Star Seo, has stressed on several public occasions that the essence of block chain technology is a distributed and irreversible database.
正如张超所述，通过对区块链公开、透明、不可篡改的数据深入挖掘，可以揭示数据背后的诸多价值，如地址画像、量化交易等。OKLink已完成对各类资产的全周期数据分析和挖掘，并针对地址交易特性建立了更为丰富的标签体系。这些基础使得他们能够逐步实现智能化分析、地址画像等功能，尤其在反洗钱等领域有着强烈的应用场景需求。
As Zhang has stated, deep digging of open, transparent and non-manufacturing data on block chains reveals many of the values behind the data, such as address drawings, quantitative transactions, etc. OKLink has completed full-cycle data analysis and excavation of various types of assets, and has developed a richer labeling system for the characteristics of address transactions. These bases allow them to move progressively towards such functions as intelligent analysis, address drawings, etc., with a strong demand for applications in areas such as anti-money-laundering.
在新冠疫情的影响下，区块链技术的价值愈发凸显，而不断涌现的安全事件也引起了业界对安全问题的高度重视，加密货币资产安全保障即将进入全新的2.0时代。
With the impact of the new crown epidemic, the value of block chain technology has become more evident, and emerging security incidents have given rise to high-priority security concerns in the industry, with the security of encrypted monetary assets about to enter a new 2.0-year era.
