Blockchain Explorer is an application that allows you to view the contents of a type database blockchain. Blockchain is the most common base, so we can see what transactions have just been approved, what are waiting for approval, how much cryptocurrency and tokens is on which account, as well as from what address and when they were sent there.

The article is part of free training - Cryptocurrencies - how to start and survive? A course for everyone!

Blockchain Explorer Ethereum

Now that you know what a blockchain explorer is, we'll explain how to use it now. The easiest way to show it in practice, how Blockchain Explorer works. We will do it on an example network of the second most important cryptocurrency, i.e. Ethereum (ETH)on which blockchain the most is based tokens.

There are many blockchain explorer applications. In our opinion, one of the most convenient is ETHplorer. There is a search engine on its main page. We can enter the portfolio address, which content we want to check, the number of the transaction whose course we want to track or the name of the token issued in the ethereum network (most often in the ERC20 standard) about which we want to learn something. We will start with this last action.

We enter the search engine Nexus and go to the page full of information about this token.

Information page of the Nexo token in the blockchain explorer

At the center of the information page, you can see a graph of the token price change.

At the top, below its name and also in the table on the left, there is information about the contract number (Contract), or the unique identifier of a given token in the blockchain network. Many tokens can have the same name. For a blockchain database, the address of the contract is important.

investor it's useful one; when he wants to transfer the given token with or on your wallet, and by default this token is not in the wallet database. Then, he must provide information about himself token symbol (in this case, NEXO), his contract address and the number of decimal places he shares (Decimals in the table on the right).

Other interesting information that we can find on this page number of transfers, made with these tokens in the entire history of their existence (Transactions), total number of tokens in circulation (Total Supply) and their current market capitalization, as well number of portfolioson which tokens are currently stored (Holders).

In the blockchain explorer we have the possibility to suspect which wallets are the richest in a given type of tokens. To do this, click the "Holders" tab.

List of the richest portfolios of a given token in the blockchain explorer

As it turns out, the two largest Nexo portfolios have a total of almost 60% of all tokens. Portfolio owners are unknown to us. At the address they do not have their name or company name. However, a bit more inquiring and looking for information about the distribution of tokens, it can sometimes be determined that, for example, a given pool of tokens is currently excluded from circulation on the so-called cold wallet and will be used only in the next years of the project ... or the portfolio belongs to the platform of a given project, therefore it collects the resources of many thousands of users. The same applies to the portfolios of cryptocurrency exchanges, which usually burst at the seams in terms of the content of accumulated funds.

How do you check the status and history of our portfolio in the blockchain explorer?

As before, we found an information page about NEXO tokens, the same now we are going to the side of our portfolioby typing in the search engine on ETHplorer his address.

Wallet address ethereum network consists of 0x at the beginning and 40 characters, including numbers and letters.

Status and history of the portfolio in the ethereum network

After going to our portfolio in the blockchain explorer, address of our portfolio is displayed on the white bar at the top. Below is a chart of exchange of its value.

In the table on the left information about the current number of stored ether coins (for me, 0,000777 ETH with the value 0,23 $). Below is the sum of ETH, which in the history of the portfolio entered and came out.

In the table on the right Balances, or account balance. It shows the number of stored ETHs and tokens. In the column on the left is the name of the token, on the right its number.

Below we have Transfers, or transfer history. We will find there information about the date of the transaction, its number (Tx), the address from which the token or ether was sent and the destination address. The right names of tokens, their number and value during the transfer and today.
