Origins of Blockchain Explorers

So, where did all this start? The concept of blockchain explorers arrived alongside blockchain technology primarily for resolving difficulties in investigating blockchains for transactions. For example, you want to verify whether a person’s claim of sending you cryptocurrencies is true or not. In some cases, the transaction might have been stalled or rejected completely.

Furthermore, navigating blockchains presented formidable difficulties, especially due to formatting of data in a specific manner. Blockchain stores and organizes data in an organized manner, thereby presenting it in an indexed and grouped format. Therefore, additional software was mandatory for ensuring better accessibility and readability of the information on blockchain.

Command-line interface offered the best instrument for exploring the information about transactions on blockchains. However, professional programming expertise is required for exploring the transactions on blockchain through a command-line interface. Therefore, an easy-to-use graphical user interface for navigating through blockchain transactions was necessary for usability of blockchain platforms.

The first-ever blockchain explorer, tailored for Bitcoin blockchain, was introduced in November 2010, just around the time when Bitcoin was going live. The explorer offered information regarding Bitcoin, and subsequently, it was shifted to, which displays real-time stats for Bitcoin blockchain. However, there were many other real-time stats pages prior to Bitcoin block explorers, such as getblockcount and getdifficulty. Here is a simple visual overview of the history of blockchain explorers –
