Keep in mind that the operation is irreversible. If you ever need to check an old transaction and that block was discarded you need to start syncing from scratch
5/16: The downside of pruned nodes is that they cannot maintain a transaction index and a rescan requires synchronizing from scratch.
It depends! If your wallet uses for example compact block filters, you can keep the filters even after pruning the corresponding blocks. That allows you to scan the filters to find which blocks you need, even if you don't have the actual blocks anymore. I think this was merged into Bitcoin Core about half a year ago.
Bitcoin Core has supported automatically pruning the blockchain since 0.11. Pruning the blockchain allows for significant storage space savings as the vast majority of the downloaded data can be discarded after processing so very little of it remains on the disk.
Manual block pruning can now be enabled by setting -prune=1. Once that is set, the RPC command pruneblockchain can be used to prune the blockchain up to the specified height or timestamp.
-prune=1and using thepruneblockchaincommand.
