How does Etherscan work?
Etherscan is a blockchain explorer that allows users to search and explore the Ethereum blockchain for transactions, tokens, addresses, and other activities. It is a powerful tool that can be used to track the movement of funds, monitor the activity of smart contracts, and research the history of Ethereum-based projects.
How Etherscan works
Etherscan works by connecting to a number of Ethereum nodes and downloading the blockchain data. It then indexes this data and stores it in a database. This allows users to search for specific transactions, addresses, or blocks, and to view detailed information about them.
Here is a more detailed explanation of how Etherscan works:
Collecting data: Etherscan connects to multiple Ethereum nodes to gather the latest blockchain data.
Indexing data: Once the data is collected, it is indexed to make it easily searchable. Indexing involves organizing the data in a way that allows for efficient retrieval based on specific parameters.
Storing data: The indexed data is then stored in a database. This database allows Etherscan to quickly retrieve and display information when users search for specific transactions, addresses, or blocks.
User interface: Etherscan provides a user-friendly interface that allows users to easily search for and view blockchain information. The interface is designed to be intuitive and accessible to both technical and non-technical users.
Real-time updates: Etherscan continuously monitors the Ethereum blockchain for new transactions and updates its database accordingly. This ensures that users have access to the most up-to-date information.
Etherscan is a valuable tool for anyone who is interested in Ethereum or who uses Ethereum-based applications. It can be used to track the movement of funds, monitor the activity of smart contracts, and research the history of Ethereum-based projects.
How to use the Etherscan gas tracker?
The Etherscan gas tracker is a tool that can be used to estimate the gas fees required to process a transaction on the Ethereum blockchain. The gas tracker displays five main pieces of information:
- Gas Price: The current gas price in Gwei. Gwei is the smallest denomination of Ether, and it is equal to 0.000000001 Ether.
- Estimate Confirmation Time: The estimated time it will take for a transaction to be confirmed at the current gas price.
- Base Fee: The minimum gas price that must be paid for a transaction to be processed.
- Priority Fee: The additional gas price that is paid to miners to prioritize your transaction.
- High, Average, and Low: The current gas prices for high, average, and low priority transactions.
To use the Etherscan gas tracker, you can follow these steps:
- Go to the Etherscan gas tracker website.
- Select the network you are using (e.g., Ethereum Mainnet, Ropsten, Kovan).
- View the current gas prices and estimate confirmation times.
- If you are sending a transaction, set the gas price you want to pay.
- Submit your transaction.
You can also use the Etherscan API to get the current gas prices. The API endpoint for the gas tracker is https://api.etherscan.io/api?action=eth_gasPrice.
Here is an example of how to use the Etherscan API to get the current gas price:
curl https://api.etherscan.io/api?action=eth_gasPrice
This will return a JSON object with the current gas price in Gwei.
The Etherscan gas tracker is a useful tool for estimating the gas fees required to process a transaction on the Ethereum blockchain. By using the gas tracker, you can avoid paying too much in gas fees and ensure that your transaction is processed quickly.
