Blockchain technology has revolutionized numerous industries, offering transparency, security, and decentralization. The blockchain explorer is a tool crucial for understanding and navigating the intricate workings of cryptocurrency networks.

In this article, we delve into the significance of this tool for both users and developers and examine how it works using the example of GetBlock’s ETH Explorer.

The Explorer: A Window to Blockchain Inner Workings

Applications that gather comprehensive data from across cryptocurrency networks, revealing the ongoing operations within these networks on a real-time basis, are commonly referred to as explorers or even “scanners”.

They offer users and developers a window into what exactly happens within these networks.

a) For Users:

It provides a user-friendly interface to track transactions, monitor smart contracts, and verify the integrity of data stored on the blockchain.

Users can seamlessly navigate through the entire transaction history, inspect wallet balances, and gain insights into the network’s activity in real-time: whether it’s verifying the status of a transaction or exploring the token holdings of a particular address.

ETH Explorer, for instance, empowers users with transparency and visibility into Ethereum’s inner workings.

b) For Developers:

Developers rely on blockchain explorers as an indispensable tool for dApp development and auditing smart contracts.

By leveraging APIs and comprehensive data visualization capabilities, developers can debug transactions, analyze gas usage, and optimize contract deployment.
A blockchain explorer facilitates the exploration of block details, transaction hashes, and contract interactions, enabling developers to gain a deeper understanding of the network’s architecture.

Moreover, it plays a vital role in ensuring the security and reliability of decentralized applications (DApps) by allowing developers to audit transactions and monitor contract executions.

Ethereum Explorer: Sourcing Decentralized Data

ETH Explorer aggregates data from nodes running on the Ethereum network. These nodes synchronize with each other to maintain a consistent and up-to-date record of transactions and smart contracts.

These apps utilize APIs to interact with these nodes, fetching information such as block headers, transaction data, and contract bytecode.

Through a combination of web scraping and direct node communication, ETH scanners construct a comprehensive view of the network, which is then presented to users and developers through an intuitive web interface.

How Ethereum Explorer Works?

As an illustrative example, let’s examine the workings of GetBlock’s ETH Explorer, a popular choice among users and developers alike.

GetBlock’s scanner tool employs its own distributed network of Ethereum nodes to source decentralized data in real time. Upon receiving a user query, the app fetches relevant information from these nodes and aggregates it into a cohesive view.

Through a combination of RESTful APIs and WebSocket connections, ETH Explorer provides users with instant access to:

• block data,
• transaction details,
• smart contract interactions.

Additionally, this blockchain explorer offers advanced features such as transaction tracing, event logs, and contract verification, enhancing its utility for both casual users and seasoned developers.

Insights from GetBlock’s ETH Explorer

As mentioned above, cryptocurrency network scanners source information from various types of nodes within the cryptocurrency network ecosystem. These nodes can be categorized into two main types: those provided by external service providers and self-hosted nodes.

External service providers, such as GetBlock, offer Remote Procedure Call (RPC) nodes for more than 55 networks that users and developers can access to retrieve blockchain data. GetBlock operates its own network of RPC nodes specifically designed to provide reliable and up-to-date information. By utilizing its own nodes, GetBlock ensures the accuracy and integrity of the data it gathers and displays to users.

In contrast, self-hosted nodes are operated and maintained by individual users or organizations within the cryptocurrency network. These nodes require users to set up and manage their own infrastructure, which can be a more complex and resource-intensive endeavor compared to relying on external providers.

Overall, whether sourcing data from external service providers or self-hosted nodes, blockchain explorers play a crucial role in aggregating and presenting information in a user-friendly manner.

Every explorer serves as a cornerstone of blockchain technology, offering users and developers a window into the inner workings of decentralized networks.

Whether it’s tracking transactions, auditing smart contracts, or exploring cryptocurrency-related data, ETH Explorer plays a pivotal role in driving innovation and transparency within decentralized ecosystems. It will remain an indispensable tool for unlocking its full potential and fostering decentralized innovation.
