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

Getting Confirmations of Ethereum Transactions using Bitcoind

As you have successfully installed and are running Bitcoin Core (BTC) on your Linux server, you can now explore how to verify the confirmations of transactions using the bitcoin-cli command-line interface. Here’s a step-by-step guide to help you achieve this:

Step 1: Identify the Transaction

First, let’s identify the transaction you’re 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 verify.

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

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

This will list all transactions with an ID matching . You can then select the desired transaction 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 display the transactions with their corresponding confirmations.

For example, if you want to verify 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’s 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 where 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 ۲. Each subsequent transaction in the list has an additional confirmation number (۳, ۴, etc.).

Conclusion

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

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