Ethereum: How can I get confirmations of a transaction using bitcoind?

Receiving Ethereum transaction confirmations with Bitcoind

Now that you have successfully installed and run Bitcoin Core (BTC) on your Linux server, you can now learn how to check transaction confirmations using the bitcoin-cli command line interface. Here’s a step-by-step guide to help you with that:

Step 1: Define a transaction

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

bitcoin-cli gettransaction -id  --count=10

Replace with the hexadecimal address of the transaction you want to verify.

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

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

This will list all transactions with an identifier matching . Then you can select the desired transaction by its index (for example, index=0 for the first transaction).

Step 2: Confirmation Check

After 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. Transactions with corresponding confirmations will be displayed in the output.

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

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

This will display a list of all transactions with their corresponding confirmations.

Interpretation of output

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

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

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

+ index: block index 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 the confirmation number ‘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 Ethereum transaction confirmations 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.

Don’t forget to always refer to the official [Bitcoin Core documentation]( for more information about the `bitcoin-cli’ command line interface and its parameters. Good luck with your requests!
