OKLink区块链浏览器实用指南篇：利用链上数据把握减半行情

进入2020年，加密货币市场最热的话题当属“减半”了。在减半行情的推动下，以BTC为首的减半币种展现出了极强的上行趋势。如何抓住这一波行情，评估正确时机？当然，这个问题的答案可以说是争议纷纷，但有一个参考标准是大家都认可的：链上数据。

In 2020, the hottest topic in the crypto-currency market was “50-50.” The BTC-led currency, driven by halving, showed a very strong upward trend. How to capture this wave and assess the right timing? Of course, the answer to this question is controversial, but there is one criterion that we all agree on: data on the chain.

区块链浏览器-链上数据解析平台

链上数据为加密货币投资提供了行情数据之外另一个维度的参考，可以说是加密货币投资中的重要指标之一。获取这些数据，最直接的方法还是区块链浏览器。

The data on the chain provide an additional dimension to the encryptive money investment, and can be said to be one of the key indicators in the encrypt currency investment. The most direct way to get these data is through the block web browser.

区块浏览器是一个专业化的区块链信息查询入口。通过区块浏览器，可以搜索交易记录，查询转账进度，也可以通过查询钱包地址来获得该地址下的余额、交易详情等信息。除了这些基本信息，大部分区块浏览器还提供可视化的统计信息图表。

Block browser is a specialized block chain information query entry. Through block browsers, you can search transaction records, query transfer progress, or you can search wallet addresses to obtain information about the balance under the address, transaction details, etc. In addition to these basic information, most block browsers provide visualized statistical information charts.

据了解，区块链浏览器是OKLink在区块链+大数据领域落地的首款基础性应用，也将是OKLink合规业务战略的重要组成部分。OKLink区块链浏览器目前支持BTC、BCH、BSV、LTC、USDT、OKCHAIN（测试网）等多币种的链上数据总览，以及最新区块/交易推送、富豪地址排名、地址/交易追溯等功能。下面，我们就以OKLink区块浏览器为例，看看如何查询数据，最大化数据背后的价值。

It is understood that the block chain browser is the first base application where OKLink landed in the block chain plus the big data area and will be an important part of the OKLink compliance business strategy. The OKLink block chain browser currently supports multi-currency data sheets such as BTC, BCH, BSV, LTC, USDT, OKCHAIN (test network) and the latest block/transaction drive, rich address ranking, address/transaction back-to-back functions. Next, we will take the example of the OKLink block browser to see how to search the data and maximize the value behind the data.

如何通过区块链浏览器获取链上数据

首先，打开OKLink（www.oklink.com），在首页搜索框选择币种，输入地址/交易哈希或者区块高度即可查看区块数据。我们以BTC为例，进行信息查询。

First, open OKLink (www.oklink.com), select the currency in the search box on the first page, and enter the address/transaction Hashi or block height to see block data. We use BTC, for example, for information queries.

可以看到，每一个区块首先会有一个区块号。此外，BTC区块数据还包括两部分：基本信息和当前区块所含的所有BTC交易数据。在交易栏里，可以看到多笔该区块所打包等交易。其中，左边是付款地址，右边的是接收地址。在付款地址的上方，还有一长串的字符“2dca4061ed9b3be552eab7f124f2b73bde62e50e438fb2dd2df6069416456044”，点击这串字符（哈希值），可以看到这笔交易的详细记录。

You can see that each block will first have a block number. In addition, the BTC block data include two parts: basic information and all BTC transactions contained in the current block. In the bar, you can see several transactions such as the packaged transactions in the block. The left is the payment address and the right is the receiving address. On the top of the payment address, there is a long string "2dca4061ed9b3be552eab7f124f2b73bde62e50e438fb2d2d2df6069164605044" and a detailed record of the transaction can be found by clicking on the string (Hashi value).

链上数据与加密货币投资

当前的链上数据，绝大部分都是交易和投资为目的产生的，链上的资金不是直接转入了交易所就是在去交易所的路上。区块浏览器提供的信息比较大而全，数据分析功能往往要视各个不同产品是否提供统计图表。链上数据分析的重点与难点是挖掘账户/地址之间的关联关系。

Most of the data in the current chain are generated for trade and investment purposes, and the funds in the chain are either transferred directly to the exchange or on the way to the exchange. Block browsers provide larger and more complete information, and data analysis often depends on whether or not different products provide statistical charts.

以BTC为例，首先我们需要从链上交易数据中统计出每日的活跃地址数，然后拿到对应时间的BTC市值，通过做对数-线性拟合建立比特币市值和活跃地址数之间的关系。按照这样的方法，我们就可以用模型对不同币种进行估值。当市值高于估值时，说明币种价值被高估，这就可以给投资加密货币提供一定的参考。

In the case of BTC, first, we need to calculate the number of active addresses per day from the transaction data on the chain, then get BTC's market value at the corresponding time, and establish a relationship between the market value of bitcoins and the number of active addresses by making logarithm-linear collating. In this way, we can model the valuation of different currencies. When the market value is higher than the valuation, it is stated that the value of the currency is overestimated, which will provide some reference for investment encoded currencies.

减半币种关键数据统计与对比

Halve Key Data Statistics and Comparisons

回到今年最热的话题“减半”，如何利用区块浏览器，分析链上数据，把握投资时机呢？打开OKLink，点击浏览器，在下拉菜单中选择币种，可以看到活跃地址数、链上交易量（链上交易笔数、链上交易量等统计图表。其中，“链上交易量”这一数据用在了很多加密货币估值方法里，作为指定加密资产网络效用的评估指标。换句话说，“链上交易量”可以用来判断某个指定加密资产是否正在被实际使用。

Returning to the hottest topic of this year, how can you use block browsers to analyse data on the chain and seize investment opportunities? Open OKLink, click on the browser, select the currency in the drop-down menu, and see statistical charts of the number of active addresses, the volume of transactions on the chain (the number of pens on the chain, the volume of transactions on the chain, etc.). In this case, the data “the volume of transactions on the chain” is used in many encrypted currency valuation methods as an indicator of assessment of the utility of designated encrypted asset networks. In other words, “the volume of transactions on the chain” can be used to determine whether a specified encrypted asset is actually being used.

我们根据OKLink的信息，统计了上半年三大减半币种BTC、BCH、BSV的活跃地址数与链上交易数据。可以看到，虽然都将迎来减半，BTC的活跃地址数在过去的一个月里依旧稳居第一。此外，BCH的链上交易量遥遥领先。这样，我们就可以推断出，目前市场中的主力交易者以做多为主，正在囤积大量BCH，因此才会出现链上交易量激增。

On the basis of OKLink's information, we have calculated the number of active addresses and chain transactions in three of the three semi-half currency BTCs, BCHs, and BSVs in the first half of the year. As can be seen, the number of active addresses in BTC has remained at the top of the chain for the past month, although it will be halved. Moreover, the number of transactions in the BCH chain is far ahead.

2月18号北京时间12点，BCH活跃地址数在小幅增长之后达到近三日峰值，结合BCH的价格来看，活跃地址数大幅在到达一个数值后迅速下跌，而价格曲线也呈现了同样的趋势。可以看到，链上数据对投资策略起到了一定的参考作用。

At 12 p.m. Beijing time on February 18, the number of BCH active addresses peaked at almost three days after a small increase, and the number of active addresses fell sharply after reaching a single value, and the price curve showed the same trend. As can be seen, the data on the chain served as a useful reference for investment strategies.

区块链以其可信任性、安全性和不可篡改性，可以让更多数据被解放出来。而我们在谈到链上数据，以及到底哪些用户需要这些数据的时候，往往忽视了一个事实，那就是：每个人都需要。举例来说，当你需要查询交易状态时，只需打开区块浏览器，输入交易哈希就能看到该笔交易的确认数。如果用户是矿工，通过区块浏览器可以获得最直接的全网算力信息与难度变化数据，从而对矿场内的资源进行更合理地分配以及相应的套保等手段。

同时，区块链的可追溯性使得数据从采集、交易、流通，以及计算分析的每一步记录都可以留存在区块链上，使得链上数据的质量获得前所未有的强信任背书，也保证了数据分析结果的正确性和数据挖掘的效果。未来，OKLink会陆续支持更多主流币种的数据查询，也会依据链上数据的这些优点，拓展更多应用场景。

At the same time, the traceability of the block chain allows each step of the data collection, transaction, circulation, and computational analysis to be retained on the block chain, allowing the quality of the data on the chain to gain an unprecedented level of trust endorsement, and ensuring the accuracy of the data analysis results and the effect of the data mining. In the future, OKLink will support more data queries in mainstream currencies, and will expand the application landscape based on these advantages of the data on the chain.
