How does Etherscan work?
Etherscan leverages the Ethereum blockchain, enabling access to all stored data. Utilizing a mix of technologies such as blockchain explorers, web3 libraries, and decentralized applications (dapps), it presents the information in a user-friendly manner. Etherscan work involves three steps mentioned below.
Etherscan utilizes an Application Programming Interface (API) to function effectively.
An API serves as a collection of programming directives facilitating interaction between distinct software components. For Etherscan, the API establishes a connection between the block explorer and the Ethereum blockchain.
Consider this analogy: an API is akin to a phone book containing a directory of names and numbers. To contact someone, search for their name in the phone book and obtain their number.
On the Ethereum network, every transaction gets transmitted to all nodes present. Subsequently, nodes authenticate the transaction and incorporate it into the blockchain.
Through the Etherscan API, the block explorer can obtain information from the Ethereum blockchain, like the transaction hash, timestamp, payment amount, and gas consumed.
Besides that, the API enables the block explorer to fetch additional details, such as the current block height and the gas price.
After obtaining data from the Ethereum blockchain, the block explorer must save it in a specific location.
Etherscan utilizes a relational database, commonly referred to as an “SQL database,” which is a variety of databases that maintains data within tables.
Every table possesses a distinct configuration, and the information within them correlates to data found in other tables. Thanks to this connection, the block explorer can effortlessly access and exhibit the data.
Producing the data marks the final stage. This is when the block explorer utilizes the Ethereum blockchain data and displays it in a comprehendible form for humans.
What Can You Do On Etherscan?
Having gained an understanding of Etherscan’s functionality, we can now explore the various tasks it enables us to perform.
Search For Addresses
Etherscan enables users to look up any Ethereum address and view all associated transactions. Additionally, it displays the address balance and the relevant smart contract code.
With Etherscan, keeping track of all activities related to specific Ethereum addresses becomes effortless.
Search For Transactions
If you have the particular identifier of a transaction, you can find it using Etherscan. This is a distinct string consisting of numbers and letters known as the transaction hash. This can help you pinpoint the transaction without difficulty.
When using Etherscan, users can learn the details of a transaction they searched for. This includes the amount transferred, the gas used in the transaction, when it occurred, as well as both addresses of the sender and recipient.
Search For Blocks
Etherscan enables you to explore and examine blocks within the blockchain.
Blockchain technology stores information in blocks, forming an interlinked chain. Each block accumulates data, from transaction records to pictures or videos. These blocks are systematically added to the blockchain in an orderly, chronological sequence.
Searching for a block can give you an abundance of information. You can easily observe the timestamp, block height, and the amount of gas used. Furthermore, you can see the transactions included within the block you search.
Search For Smart Contracts
Etherscan empowers users to actively explore and locate smart contracts. As you delve into a specific smart contract, the platform unveils its underlying code for your perusal.
Auditing a smart contract’s code for errors or vulnerabilities is possible by viewing the transactions made to that contract and its current balance. This provides an efficient way to review the integrity of any given smart contract, ensuring that it can safely be used without any risk of faults.
How To View Transactions And Wallets On Etherscan
To explore a wallet address on Etherscan, open the “Transactions” tab. This will show you all the Ethereum transactions (Txns) conducted and all the gas (Gwei) consumed associated with that specific wallet address. Delve deep and discover all the valuable information regarding the activity in the wallet.
On Etherscan’s Homepage, type in the wallet address and click “Search” to be directed to a webpage that shows all the information concerning that particular wallet. The data included will be its ETH balance, its value in US dollars, and an overall view of the wallet’s transaction history.
To view more detailed information about the transactions involving an address, click on the Transactions tab in the wallet. Doing this will open a new page displaying each transaction’s transaction ID, block height, and confirmation time.
The block height indicates which block the transaction was incorporated in. Not only that, but it also reveals the source and beneficiary addresses, together with the complete transaction fee. This knowledge offers an enhanced level of confusion and intricacy.
To discover and trace a single transaction, users need the transaction hash or TxHash, a distinct alphanumeric code that specifically tags the transaction on the blockchain. By searching the TxHash, individuals can track and research any particular transaction from the blockchain with accuracy and confidence.
When users type in the Transaction Hash into the search bar on Etherscan, the website will produce a list of information on the related transaction. Going to the Transactions tab enables the users to view additional details, including the transaction status (successful, pending or failed) and the amount transferred.
