Bitcoin: Bitcoin-qt and Bitcoind see the bitcoin.conf file differently

Conflicting Bitcoin Core Files: A Guide to Understanding the Difference Between Bitcoin-Qt and Bitcoind

When using Bitcoin Core (BTC) on a Raspberry Pi, it’s not uncommon to have different versions of the software installed side by side. Specifically, with Bitcoin 25.1, there can be confusion about how to manage different files in the bitcoin.conf configuration file.

In this article, we’ll explore the differences between the Bitcoin-Qt and Bitcoind binaries provided by the BTC package, as well as their proper locations in the bitcoin.conf file.

What are Bitcoin-QT and Bitcoind?

Bitcoin-QT is a standalone application that acts as an alternative to Bitcoind. It’s essentially a Qt-based interface for interacting with your Bitcoin wallet and blockchain. While Bitcoind is the core software that runs the Bitcoin network and wallet functions, Bitcoin-QT acts as a front-end application.

In most cases, Bitcoin-Qt and Bitcoind can coexist on the same system, each serving different purposes:

  • Bitcoind is responsible for managing the Bitcoin network and updating the blockchain.
  • Bitcoin-QT provides an interface through which you can interact with your wallet and manage transactions.

However, their location in the bitcoin.conf file is different. The location of the files can affect how the system configures and uses them.

Understanding the location of Bitcoin-Qt and Bitcoind in bitcoin.conf

If you are using Bitcoin 25.1 on your Raspberry Pi, you may be confused between the two different files mentioned above:

  • bitcoin.conf usually provides general settings for the Bitcoin Core installation.

* The .bitcoin/bin/ directory may contain files specific to each application.

Here’s what they might look like in the bitcoin.conf file:


bitcoin.conf

[seed]

network=mainnet

Specify the network to use

displayname=My Bitcoin Core

In this example, the “[core]” section contains general settings for the base installation. The “.bitcoin/bin/” directory likely contains some Bitcoind-related files, such as the bitcoind executable and possibly a “settings.conf” file.

However, when using Bitcoin-Qt, you will need to change the “display name” setting in the “[core]” section to reflect your choice:


bitcoin.conf

[seed]

network=mainnet

Specify the network to use

displayname=BTCQt

Set the display name for Bitcoin-QT

In this case, the “display name” setting will change to reflect the use of Bitcoin-QT.

Handling Conflicting Files in bitcoin.conf

To resolve conflicts between two different files, follow these steps:

  • Update the [main] section

    : Make sure that the main installation settings are accurate and up-to-date.

  • Check for Conflicting Configurations: Check the “display name” setting to see if it matches one of the applications installed on your system.

If you understand how Bitcoin-Qt and Bitcoind interact with the corresponding locations in the bitcoin.conf file, you should be able to resolve any conflicts that arise during use.

In summary, while Bitcoin-QT and Bitcoind can coexist, handling conflicting files requires attention to detail. By following the steps below, you can ensure that your Bitcoin Core installation runs smoothly on your Raspberry Pi.
