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. + ## Debugging This section contains general instructions for debugging failed installs or problems encountered with Monero. First, ensure you are running the latest version built from the Github repo.
