What is Etherscan and why you need it?
Etherscan is a blockchain explorer and analytics platform that tracks and sorts the Ethereum blockchain's data into easily navigable information. It acts as a search engine for Ethereum-related activities, allowing users to retrieve detailed information about ERC-20 token transactions, NFT mints, smart contract details, wallet balances, and more.
Blockchain Explorers
Blockchain explorers are search engines that allow users to access information about specific blockchains and wallet addresses. This includes details such as amounts transacted, sources and destinations of funds, and the transactions' status.
Blockchain explorers function by utilizing Application Programming Interfaces (APIs) and blockchain nodes to aggregate various datasets from a blockchain. The gathered data is then organized using a database and presented to the user in a searchable format. This systematic process enables users to extract virtually any data related to transactions, wallets, and blockchains.
The key functionality of a blockchain explorer lies in its ability to provide a user-friendly platform for users to access intricate details of transactions, including the amount transacted, sources and destination of funds, and the status of the transactions. Essentially, it allows users to view the transaction history of any wallet address, including the latest transactions and amounts. This significantly improves transparency on a blockchain.
How Does Etherscan Work?
The inner workings of Etherscan rely on a system called JSON-RPC, which interacts with an API to retrieve Ethereum data. In simple terms, Etherscan sends different queries and requests to a Remote Procedure Call (RPC) endpoint and receives the latest data in return.
RPCs are protocols used to communicate with a node (or multiple nodes) on a blockchain network from a remote system or application. RPCs allow external programs or systems to interact with the blockchain node to perform various tasks such as querying data, submitting transactions, or executing specific functions within the blockchain network. This enables developers to build applications that interact with the blockchain without needing to run a full node locally.
This system allows Etherscan to maintain an organized data record in real time, constantly retrieving and adding data in a structured manner. The result is a platform that can respond accurately and almost instantly to users' requests about almost any Ethereum-related activity.
Etherscan presents this near real-time data to users through its user-friendly interface. Users can search for any desired Ethereum data and navigate different sections of the website to find what they're looking for.
