This can reduce the disk usage from over 100GB to +around 2GB. + +Running a node in pruned mode disables the RPCs `importwallet`, `importaddress`, +and `importprivkey`. + +To enable block pruning set `prune=` on the command line or in `bitcoin.conf`, +where `N` is the number of MiB to allot for raw block & undo data. + +A value of `0` disables pruning. The minimal value above `0` is `550`. Your +wallet is as secure with high values as it is with low ones. Higher values +merely ensure that your node will not shut down upon blockchain reorganizations +of more than 2 days - which are unlikely to happen in practice. In future +releases, a higher value may also help the network as a whole because stored +blocks could be served to other nodes. + ### Reduce Traffic Some node operators need to deal with bandwith caps imposed by their ISPs.
