What Is A Blockchain Explorer?

Spread the love

The open design of Bitcoin and its infrastructure makes it easy to look at network info. One way to achieve this is by using a blockchain explorer. These useful resources offer access to a variety of data sets at no extra cost.

Leveraging Blockchain Transparency

Building a blockchain explorer would not be feasible without the native functionality of the blockchain. The technology is clear, accessible and timeless. If the data is registered on the blockchain and validated by the network, it cannot be updated in the future.

Systems such as Bitcoin and Ethereum mean that all knowledge is freely available. Any citizen on this planet has free access to the data and data flowing through these networks. A blockchain explorer can be a viable method to make data more accessible and easier to ingest.


What Is A Blockchain Explorer?

A blockchain explorer provides a way for anyone to look at past and present network activity for a blockchain ecosystem. It does not apply to just Bitcoin, as every cryptocurrency or public blockchain can provide this transparent access. For Bitcoin, different explorers exist, such as Blockchair, Blockchain.com, et cetera. These platforms offer the same functionality, but some may have better charts and in-depth data analysis.

When using a blockchain explorer, a lot of data becomes accessible to the user. This includes past and current network transactions, the size of network blocks, a block’s hash, the mining difficulty of the network, and so forth. Unlike the traditional financial system, transparency is critical when dealing with cryptocurrencies and blockchains.

“Don’t Trust, Verify” is a common saying in this industry. Thanks to blockchain explorers, everyone can verify the data, rather than trusting data aggregators or other people.

The Technical Aspect

Contrary to what some may think, a blockchain explorer is not just a website. It is a living organism that continually monitors a public blockchain for additional data and statistics. There is a Command Line Interface to interact with this “database” of information to obtain this data. As this is not the most user-friendly way of presenting data, a Graphical User Interface is required. That Interface is the blockchain explorer.

Common datasets to be presented through a blockchain explorer include:

  • The current price of Bitcoin in US Dollars
  • The current network hashrate – provided through proof-of-Work or proof-of-Stake
  • The mining difficulty and next estimated difficulty
  • Current and past transactions, as well as the daily network performance
  • Mempool size (the mempool is the collection of network transactions not yet processed or confirmed by the network)
  • The circulating supply of Bitcoin
  • The size of the Bitcoin blockchain
  • The number of network nodes
  • A lot more details that are intriguing and fascinating

A blockchain network contains many different metrics that all reflect crucial aspects of keeping the network up and running.

Investigating The Bitcoin Rich List

Even in the Bitcoin world, several addresses will have more BTC than the regular user can collect. These addresses are part of the “Rich List,” a metric one can find on websites such as BitInfoCharts. It contains the addresses holding the most BTC, as well as when users last moved funds.

When we take one of the addresses from this list, address “1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF” and enter it into the Blockchair Bitcoin Block Explorer, we can analyze a lot of data.

We are presented with the address information, its balance, and when the address last received a Bitcoin transaction. The block explorer also depicts the number of transactions to data, as well as its QR code.

Below that, we have an overview of the Bitcoin transactions involving this particular Bitcoin address. The value of every transaction can be denominated in BTC or US Dollar. All of the past and current network activity applying to “1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF” is available for analysis immediately.

After clicking on an individual transaction – this one, for example – we can see the block ID of when the network broadcasted it through, the time of the transaction, its fee, who sent it, and whether its privacy score.

This latter metric is found on select block explorers. A higher score indicates it is harder to link this address to an online or real-world identity. This score of 50 is not great, but this transaction may not require a layer of privacy either.


Understanding the intricacy of bitcoin and blockchain technologies is also viewed as a steep learning curve. That’s not always the case, due to the blockchain explorers and other instruments at one’s disposal.

It helps to see the open existence of these modern financial networks. In addition, this makes it possible to flag highly illegal transactions to deter bribery and money laundering. It does compromise anonymity, but developers have never developed networks like Bitcoin and Ethereum to provide privacy.
