Ethereum: How to get confirmations of a transaction using bitcoind?

Get Ethereum Transaction Confirmations Using Bitcoind

Now that you have successfully installed and running Bitcoin Core (BTC) on your Linux server, you can now explore how to check transaction confirmations using the “bitcoin-cli” command line interface. Here is a step-by-step guide to help you do it:

Step 1: Identify the Transaction

First, let’s identify the transaction you are interested in. You can use the following command to list all transactions on your Bitcoin Core instance:

bitcoin-cli gettransaction -id  --count=10

Replace “” with the hexadecimal address of the transaction you want to check.

For example, if you want to verify a specific transaction, say txid123, use the following command:

bitcoin-cli gettransaction -id txid123 --count=10

This will list all transactions with an ID that matches . You can then select the transaction you want by its index (e.g. index=0 for the first transaction).

Step 2: Verify confirmations

Once you have identified the transaction, use the following command to verify its confirmations:

bitcoin-cli gettransaction -id txid123 --confirm --count=10

The --confirm option will prompt you to enter a confirmation number for each block. The output will show the transactions with the corresponding confirmations.

For example, if you want to check the confirmations of the first 10 blocks:

bitcoin-cli gettransaction -id txid123 --confirm --count=10

This will list all transactions with their corresponding confirmations.

Interpreting the output

The output of the command may vary depending on your system and the number of transactions. Here is a general breakdown:

• The gettransaction command returns a JSON object containing information about each transaction, including its ID, block number, timestamp, and confirmations.

• Each confirmation is represented by an array of objects, where each object contains the following keys:

+ index: The index of the block in which the transaction was confirmed.

+ previoushash: The hash of the previous block in the chain (not relevant to your question).

+ timestamp: The timestamp when the confirmation occurred.

Example output

{
"result": {
"txid": "0x123456789012345678901234567890",
"vsize": 100,
"wbits": 0,
"fee": -1500000000,
"nonce": 20000,
"blockhash": "0xabcdefxyz"
},
"txns": [
{
"index": 1,
"previoushash": null,
"timestamp": "2023-03-16T14:30:00Z",
"confirmations": 2
}
]
}

In this example, the first transaction has a confirmation number of 2. Each subsequent transaction in the list has an additional confirmation number (3, 4, etc.).

Conclusion

Using the bitcoin-cli command line interface, you can now verify the confirmations of Ethereum transactions on your Bitcoin Core instance. This feature is especially useful when working with large data sets or when you need to ensure the integrity of your blockchain.

Remember to always consult the official [Bitcoin Core documentation]( for more information on the bitcoin-cli command line interface and its options. Happy querying!
