区块链是公开透明的分布式账本，每个全节点都有一个完整的账本。想查询账本中的信息，要怎么做，你需要区块链浏览器这个工具来帮你。
Block chains are publicly and transparently distributed accounts, with a complete account book for each node. To search for information in the ledger, you need a block chain browser to help you.
1.什么是区块链浏览器
1. What is a block chain browser?
区块链浏览器可以简单理解为“区块链+浏览器”。
Block chain browsers can be easily understood as " block chain plus browsers ".
区块链上记录的内容，都可以通过区块链浏览器查询。
The contents recorded on the block chain can be searched through the block chain browser.
每一条区块链都有自己的区块链浏览器，如比特币有比特币区块链浏览器，以太坊有以太坊区块链浏览器，公信宝有公信宝区块链浏览器，区块链浏览器不可以跨链查询，如以太坊的只能查询以太坊。
Each block chain has its own block chain browser, e.g. Bitcoin has a bitcoin block chain browser, ethay has an Itha block chain browser, public treasures have a public trust block chain browser, and block chain browsers are not allowed to cross the chain, e.g. Ether has only access to Etheria.
不同区块链浏览器可以查询到的信息也不同，通常可以查询到区块中包含区块高度、哈希值、发布时间和开采的矿工、交易信息等等，部分还可查询全网算力、算力难度等内容。
The information that can be accessed by the various block chains browsers is also different and usually contains block heights, Hashi values, release times and mining miners, trade information, etc., as well as part of the search for full-network computing, difficulty in calculating, etc.
2.以太坊区块链浏览器—Etherscan
Etherscan
下面主要讲以太坊区块链浏览器，其区块信息查询浏览器是Etherscan, 网址 https://etherscan.io/，使用Etherscan可以查看自己的交易详情以及以太坊中的任何信息。
The following is mainly a sectional block-chain browser with a block information query browser, Ethercan, at https://otherscan.io/, which allows you to view your transaction details and any information in Ethercan.
不习惯英文，可以输入网址https://etherscan.io/language.aspx，切换为中文，不过翻译的一般，浏览器界面如下：
If you are not used to English, you can enter the web site https://otherscan.io/language.aspx and switch it to Chinese, although normally translated, the browser interface is as follows:
以太坊区块链浏览器可查询到的信息非常多，以下讲其中的三点：
There is a great deal of information that can be found in the Tetau block chain browser, three of which are described below:
1）交易信息查询
1) Transaction Information Query
Step1:打开浏览器输入地址或交易哈希值
Step1: Open browser to enter address or transaction Hashi value
Step2:查看查询结果
Step2: View Query Results
上图是地址（0x7B74C19124a9ca92C6141A2ED5F92130fc2791F2)的所有交易信息以及资产数量。点击某一条交易 TxHash 可以查询交易的详细信息。
The figure above shows all transactions and the number of assets at the address (0x7B74C19124a9ca92C6141A2ED5F92130fc2791F2).
注：以上地址是在浏览器中随意挑选的
Note: The above addresses are randomly selected from the browser
2）ERC-20 代币查询
2) ERC-20 Currency Query
ERC-20是以太坊上的一种 Token 标准，现在很多代币就是符合ERC-20标准的代币，可以使用 Etherscan 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：
The ERC-20 is a Token standard in the Taiku, and now many of the tokens are those that meet the ERC-20 criteria. The Ethercan can be used to query Token and related information that meet the ERC-20 criteria. For example, the currency is KEY:
Step1:打开代币的View Tokens
Step1: View Tokens, which opens the token.
Step2:输入KEY点击Find
Step2: Enter KEY on Find
Step3:选中KEY对应的Token Contract点击
Step3: Select the TOKEN CONTACT click for KEY
Step4:查看KEY代币相关信息
Step4: look at KEY money information.
3）合约代码查询
3) Contract Code Query
3.区块链浏览器可获取数据做分析
3. Block-chain browsers can obtain data for analysis
用好了区块链浏览器，可以分析追踪查询到很多信息。
With a block chain browser, a lot of information can be traced for analysis.
