如何利用以太坊区块链浏览器查询链上数据？

对于区块链领域的投资者而言，无论是参与交易所的IEO还是进行代币投资，都需要了解投资项目的价值以及代币的分配情况。这时，最常见的方式就是通过区块链浏览器查询数字资产的链上详情。下面，我们就以Tokenview的以太坊区块链浏览器为例，来介绍一下如何查询以太坊链上的相关信息。

For investors in block chains, whether IEOs participate in the exchange or invest in tokens, there is a need to understand the value of investment projects and the distribution of tokens. In this case, the most common way is to search for details on the digital asset chain through a block-chain browser.

1.我们需要在浏览器搜索框中输入要查询的以太坊地址。以地址0xe7af11370c3bab51230d8307454350bdf6d68f4a为例，以下是我们的搜索结果。

1. We need to type in the browser search box an address to search for. For example, the address 0xe7af 11370c3bab51230d83305435bdf6d68f4a is our search result.

在地址信息页面，我们可以查看到该地址的余额、代币余额、交易笔数、余额排行和Nonce等信息。

On the address information page, we can look at the balance of the address, the currency balance, the number of transaction notes, the line of the balance and Nonce.

我们也可以通过点击“复制”快速复制地址，点击右侧的“二维码”展示该地址的二维码形态，方便我们通过手机钱包进行扫码转账。

We can also display the two-dimensional code form of the address by clicking on a " copying " quick copy address and clicking on a " two-dimensional code " on the right, so that we can scan the transfer through our mobile wallet.

根据地址信息，我们可以得知该地址属于MCH并持有210.69个ETH。此外，该地址自创建以来的交易总笔数为538笔，并且在以太坊网络中的所有地址余额排名为25675名。

On the basis of the address information, we can find out that the address belongs to the MCH and holds 210.69 ETHs.

Nonce指的是，由这个地址发起的交易，每增加一笔，nonce就加1。因此，该地址发起的转账次数为458次，而总转账次数为538次，其中包括作为接收方的交易。

Nonce refers to the number of transactions initiated by this address, plus one for each additional transaction. Thus, the address initiates 458 transfers, compared to a total of 538 transfers, including transactions as recipients.

以太坊拥有众多合约和Token，如ERC20和ERC721等。这里的代币余额统计了该地址下的所有Token余额。

There are a number of contracts and Tokens, such as ERC20 and ERC721.

我们还可以追溯每项Token的近期交易记录和查看地址近半年内的余额变化图。这些信息有助于我们更好地理解项目的具体情况，降低投资风险。

We can also trace every Token's recent transaction record and look at the balance change map for almost six months. This information helps us to better understand the specifics of the project and to reduce investment risk.

总的来说，在考虑投资某种代币资产之前，我们可以通过以太坊区块链浏览器查询相关的链上数据，从而更好地了解项目的实际情况，减少投资风险。

In general, before considering investing in a token asset, we can access the relevant chain data through the Taiwan block web browser to better understand the actual situation of the project and reduce investment risk.
