Performing Bitcoind in Pruning Mode: a guide
In the world of cryptocurrency and blockchain development, performing multiple nodes on a single computer can be beneficial for a variety of reasons, such as increased safety and faster transaction processing times. However, this also means that older blocks are being discarded, leaving less data available to users like you.
One way to mitigate these problems is through pruning mode, allowing you to perform only the necessary information of each block on your local machine, discarding most of what is stored elsewhere. In this article, we will go through a step -by -step guide on how to install and configure Bitcoind in pruning mode.
** Why pruning your bitcoind?
Before we dive into the process, we will discuss quickly why you may want to execute your bitcoind in pruning mode:
* Security : When discarding older blocks, you reduce the attack surface for possible safety vulnerabilities.
* Speed : Performing a complete knot can be slower than running a pruning node, optimized for performance.
* Space : With more data stored, it has less us on the local machine can help in storage space problems.
Pruning bitcoind: a step by step guide
- Install pruning node software
: First, download and install the official pruning node software on the [Official Website] ( The latest version is usually available on Github.
- You can do this by editing the
config.jsonfile in the pruning node root directory.
Here are some example configuration options:
Prune.minblock: the minimum number of blocks to be maintained. Set it as a lower value if you want more data stored on your local machine.
Prune.maxblock: the maximum number of blocks to be maintained. Set so high enough to buy the pruning process is efficient, but it is not so high that it takes a long time to complete.
`Json
{
"Prune": {
"Minblock": 100000, // Keep at least the first 10 million blocks
"Maxblock": 2000000 // Keep up to 2 million blocks
}
}
- Start the pruning node : After setting the settings, start the pruning node using
./Node.sh. Make sure you are in the directory where your pruning knot software is installed.
`Bash
./node.sh -f config.json
`
- Check your configuration
: Once started, make sure your pruning configuration is correct, checking updates or running a complete knot on your machine to ensure it is working as expected.
- Run the Bitcoind in Pruning Mode : To execute Bitcoind in pruning mode, use the
prunecommand instead of the normal ‘bitcoindcommand.
Bash
./node.sh -c prune -f config.json
`
Troubleshooting tips
- If you find problems with the pruning node locking or not working properly, make sure your configuration is correct and try to rest the pruning node.
- Remember that pruning nodes can consume more CPU and memory than normal nodes; Therefore, closely monitor the use of resources.
Following these steps and adjusting pruning settings according to your needs, you can effectively execute Bitcoind in pruning mode. Remember to regularly update your configuration and test your configuration before deploying it on a live network.
Conclusion
Bitcoind pruning is a great way to balance safety, performance and storage space. Following these steps and adjusting the settings according to your specific use case, you can optimize your pruning knot for the best results.
