'Pruning' allows node operators to save 2/3 of storage space while keeping
|
|
the full transaction history. Pruning works by removing 7/8 of unnecessary
|
|
ring signature data. The 1/8 remaining data will be available to the other
|
|
nodes and will be used to sync with the network. Other pruned nodes will
|
|
have a random 1/8 of the data, which they will also make available to the
|
|
network. There are no privacy or security downsides when using a pruned
|
|
node.
|
|
|
|
There are three ways to prune:
|
|
|
|
- *Synchronize a pruned node from scratch:* You will download and sync only
|
|
1/3 of the full blockchain.
|
|
|
|
- *Prune an existing node:* The already existing blockchain will be pruned,
|
|
but this will not result in a smaller blockchain. Instead, it will mark
|
|
parts of the file as free, so that future data will use that free space,
|
|
causing the file to not grow until free space grows scarce.
|
|
|
|
- *Create a new pruned blockchain from a full one:* A full blockchain that
|
|
you already have will be used to create a new, pruned blockchain.
|
|
|
|
Pruned nodes are very useful and preferable to @remote-nodes, but if
|
|
possible, users should run a full node and opt for pruning only in case if
|
|
necessary.

The 'database pruning' feature [was
|
|
added](https://github.com/monero-project/monero/pull/4843) on January
|
|
2019. See the [blog post]({{ site.baseurl }}/2019/02/01/pruning.html) for
|
|
more information.
