Finding a Block by Transaction ID (TXID) on Ethereum with Bitcoin CLI

You're not alone in your quest for accurate block information, especially when working with multiple cryptocurrency exchanges or wallets. In this article, we'll explore the best ways to find a specific block by transaction ID (TXID) using Bitcoin CLI.

Background: Understanding TXIDs and Blocks

Before diving into the solution, it's essential to understand how TXIDs work in Ethereum. A TXID is a unique identifier for a transaction on the Ethereum blockchain. Each transaction has a corresponding TXID, which can be used to retrieve information about the transaction, including the block it was mined on.

Method 1: Using gettransaction command with -id option

The Bitcoin CLI provides a way to query transactions using the gettransaction command. You can use the -id option to specify the TXID of the transaction you're looking for.

To find a specific block by TXID, follow these steps:

Start your Bitcoin CLI session: bitcoin-cli

Use the gettransaction command with the -id option and your desired TXID.

bitcoin-cli gettransaction -id

Replace with the actual TXID you want to find.

Method 2: Using getblock command

If you need more information about the block, such as its hash or count, you can use the getblock command. You can also combine both methods by using the -id option for transactions and then filtering blocks based on their hash or count.

To find a specific block by TXID, follow these steps:

Start your Bitcoin CLI session: bitcoin-cli

Use the gettransaction command to retrieve transaction data.

bitcoin-cli gettransaction -id

Once you have the transaction data, use the getblock command with the -txid option to filter blocks by TXID.

bitcoin-cli getblock -txid

Tips and Variations

If you want to find a block that contains multiple transactions, use the -toaddress option with the transaction ID. For example: bitcoin-cli gettransaction -id -toaddress

To find blocks within a specific range, add the fromblock or toblock option followed by your desired start and end block IDs. For example: bitcoin-cli getblock -txid --from 1234567890 --to 2345678901

Conclusion

Finding a block by transaction ID (TXID) can be achieved using both the gettransaction command with the -id option and the getblock command. By understanding how TXIDs work on the Ethereum blockchain, you'll be able to efficiently locate specific blocks within your cryptocurrency portfolio or exchange data.
