## Pruning
As of May 2020, the full Monero blockchain file is about 80 GB. One can store a pruned blockchain, which is about 28 GB.
A pruned blockchain can only serve part of the historical chain data to other peers, but is otherwise identical in
functionality to the full blockchain.
To use a pruned blockchain, it is best to start the initial sync with --prune-blockchain. However, it is also possible
to prune an existing blockchain using the monero-blockchain-prune tool or using the --prune-blockchain monerod option
with an existing chain. If an existing chain exists, pruning will temporarily require disk space to store both the full
and pruned blockchains.
