一、什么是区块链浏览器
I, what is a block-chain browser
区块链浏览器简单来说是一种搜索工具，我们通过输入某钱包地址或某笔交易ID，就可以查询此钱包的余额和任意一笔交易的详细信息：比如当前比特币的转账费用是多少、给你转账的地址有多土豪、一笔转账究竟何时到账……当然，我们也可以通过输入块高，块哈希等来搜索某一特定区块的所有内容。
The block chain browser is simply a search tool, and by entering a wallet address or a transaction ID, we can search for details of the balance of the wallet and any transaction: for example, how much bitcoin is being transferred, how much money is being transferred to you, and when a transfer is going to be accounted for.
有了区块链浏览器之后，每一个区块所记载的内容都可以从区块链浏览器上进行查阅。每一条区块链都有自己的浏览器，用户不能通过区块链浏览器进行跨链查询。更具体的例子，比特币只能通过比特币浏览器查询，而不能使用以太坊浏览器查询。有些网站为了方便用户查询，将多条链的区块链浏览器集中在一个网站上。
With a block-chain browser, each block can be viewed from a block-chain browser. Each block-chain has its own browser, and users cannot cross-link through a block-chain browser. More specifically, Bitcoin can only search through a bitcoin browser, rather than using an e-discovery browser.
二、常见的区块链浏览器有哪些?
What are the usual block-chain browsers?
Blockchain.org
[xxid]60,3081[/xxid]
Blockchain.com，网站最近改为Blockchain.org，应该是最出名的比特币浏览器了。根据现在浏览器标准，具备基本的功能：按照区块、交易或者地址进行搜索，安全可靠，界面美观。还可以查看到过去24小时与比特币活动相关的财富统计数据。
Blockchain.com, recently changed to Blockchain.org, should be the most famous bitcoin browser. According to current browser standards, there are basic features: search by block, transaction, or address, secure, interface. You can also look at wealth statistics associated with Bitcoin activities over the past 24 hours.
Blockchair.com
[xxid]60,3086[/xxid]
“你可以搜索到区块链世界的一切内容”这是Blockchair.com的口号，这个网站也确如它的口号所言。可搜索BTC、BCH和ETH区块链上各种有价值的信息，其中包括内存池的大小、手续费、节点的数量、难度值。Blockchair一直在不断完善，其海量搜索也一直是无敌的。你甚至可以在上面搜索编入区块链的词语或者段落，好奇者可以到上面搜索看他们的故乡、球队或者孩子的名字是不是已经永久刻录在区块链上。
"You can search all the contents of the block chain world." This is the slogan of Blockchair.com. This website is exactly what it says. You can search for all the valuable information on the BTC, BCH and ETH blocks, including the size of the memory pool, the fees, the number of nodes, and the difficulty. Blockchair has been perfecting it, and the amount of search has been invincible. You can search even the words or paragraphs of the block chain, and curious people can search it to see if the names of their homes, teams or children have been permanently inscribed on the block chain.
Tokenview.com是一个支持多个区块链的浏览器，由一个中国团队开发，于今年初上线。网站还不是很完善，有些翻译上的小问题，但是支持的区块链数量是无人能敌的。支持20多个主流区块链的搜索，一个浏览器就可以满足搜索大部分区块链交易和地址的需求。该网站还有一份站上各个币种的富人榜。
Tokenview.com, a browser that supports multiple block chains, was developed by a Chinese team and went online at the beginning of the year. The website is not yet perfect, with minor translation problems, but the number of block chains supported is unmatched. In support of more than 20 mainstream block chains, a browser can satisfy the need to search for most block chain transactions and addresses.
Etherscan.io
[xxid]60,3078[/xxid]
市面上有不少做得不错的以太坊浏览器，但Etherscan.io是最受欢迎的，而这是有原因的。这个浏览器在查找智能合约、Gas费用、浏览DEX活动做得尤其好。但最重要的Etherscan用于查看钱包地址里的代币余额，其他一些提供以太坊相关服务的钱包例如Metamask和Myetherwallet则不能总是那么可靠。
The market has a lot of well done Etheria browsers, but Ethercan.io is the most popular, and for some reason. This browser is particularly good at finding smart contracts, Gas fees, and viewing DEX activities. But the most important Etherscan is used to view the currency balance in wallet addresses, while other wallets that provide Ether-related services, such as Metamask and Myethherwallet, are not always reliable.
Bitcoin.com
[xxid]35,2891[/xxid]
最后，我们还要提一下Bitcoin.com的区块浏览器。界面简洁，极简主义的设计让你可以非常快速查找BCH和BTC网络上的交易。支持扫描二维码查看钱包地址，钱包底部还有一个按键可以切换新旧BCH地址，还有其他一些功能。
Finally, we would like to mention Bitcoin.com's block browser. The interface is simple and extremely simple design allows you to search very quickly for transactions on the BCH and BTC networks. A two-dimensional view of the wallet address is supported, and there is a key at the bottom of the wallet to switch to the old and new BCH address, as well as some other features.
btc.com
[xxid]60,3082[/xxid]
btc.com提供便于使用的区块查询服务和工具，拥有丰富的统计数据。目前隶属于比特大陆旗下，比特大陆是一家专注于高速、低功耗定制芯片设计研发的科技公司，拥有低功耗高性能的16nm工艺集成电路的量产经验，成功设计量产了多款ASIC定制芯片和集成系统。重点面向世界的中小型企业及个人用户，目前公司客户遍及全球多个国家和地区。

三、如何查询区块链交易信息?
III. How to query block chain trading information?
以btc.com为例，打开后网站分为三大板块：最近出块、矿池算力和网络状态。
In the case of btc.com, the site was opened and divided into three main sections: the recent release of blocks, the capacity of the ponds and the state of the network.
1、最近出块：可以看到当前比特币的最新区块高度是多少，经常有团队说在比特币某某区块高度的时候分叉一个新的币，就可以查看这个来估计分叉时间。
1. More recently: See how high the current latest bitcoin is, and there are often groups that say that they can split a new coin at the height of a particular bitcoin, and look at this to estimate the time of the split.
2、矿池算力：可以看到当前各大矿池的算力数据。
2. Pond computing: Data on the capacity of current major ponds can be seen.
3、网络状态：在转账的时候需要关注这个版块的两个信息是：未确认交易和当前最佳手续费。如果未确认数量很大，在转账的时候肯定会很慢，要做好心理准备。如果转账着急就可以参考当前最佳手续费来填写矿工费缩短交易时间。
3. Network status: The two messages that need to be taken into account when transferring the block are: unacknowledged transactions and current best handling fees. If not identified, the transfer must be slow and psychologically prepared.
以地址 1DPTGteNKY7AhvLT5cTCP5bAtga74QjksT 为例查询交易信息：
Queries transaction information by address 1DPTGtNKY7AhvLT5cTCP5bAtga74QjksT:
点击搜索后就可以看到下图的界面。会显示总接收的比特币数量、总的交易数量和历史交易。Txid就是这笔交易的交易编号，当你充值到交易所未到账时，交易所会让提供转账的Txid，就像我们淘宝购物出问题客服会让你提供订单编号一样。
Click on the search to see the interface below. The total number of bitcoins received, the total number of transactions and historical transactions are shown. Txid is the transaction number of the transaction, and the exchange will allow Txid, who provides transfers, as if we were shopping for trouble suits that would allow you to provide order numbers.
点击Txid可以查看这笔交易的详细信息，比如矿工费和确认数。确认数是指有多少个区块包含了你的这笔交易记录。
Click on Txid to see details of the transaction, such as miners’ fees and confirmations. The confirmations refer to how many blocks contain your transaction records.
四、如何查询以太坊ERC20代币(token)相关信息?
iv. How to access Ether's ERC20 token information?
以太坊区块链浏览器可以查询查询符合 ERC-20 标准的Token以及相关信息。以币乎的代币KEY为例，使用的网站是Etherscan.io：
Token, which meets the ERC-20 standard, and related information can be consulted by the Taiwan Block Chain Browser. In the case of currency KEY, the website used is Etherscan.io:
1、打开代币的View Tokens
1. View Tokens, which opens the token
2、输入KEY点击Find,选择对应的Token
2. Enter the KEY click on Find and select the corresponding Token
3、查看KEY代币相关信息
Three. Check the KEY tokens.
如果懂技术, 可以去看Token的合约代码, 不同的项目有不同的代币发行方式，如锁定等，可以通过这些信息判断是否按其白皮书中的规划执行。还是以KEY为例，点击上图中的ERC-20合约即可查询，如下图：
If you understand technology, you can look at Token’s contract code, and different projects have different forms of currency issuance, such as locking, which can be used to determine whether to execute as planned in his white paper. Or, for example, Key, click on the ERC-20 contract in the figure above, as follows:
4、查看KEY代币的持仓情况
Four, check KEY's holdings.
我们通过点击tokenholder可以看到这个币的持仓情况。并且根据白皮书来了解这个币的持有情况。
We can see the hold of the coin by clicking on tokenholder. And we can see the hold of the coin on the basis of the white paper.
可以通过查看holder的持币变化并且结合市场的变化，来做一些基础的投资判断。利用好区块链浏览器，可以让我们获取更多有用的信息。
Some basic investment judgements can be made by looking at holder's currency changes and taking into account market changes. Using good block chains browsers, we can get more useful information.
