I would like to do a fast bootstrap of the Ethereum blockchain with minimal disk space usage. Can geth do a pruned fast sync?

  • Actually, only Geth can do a fast sync, and yes, it results in a pruned database :) Mar 29, 2016 at 10:07

Use geth --fast:

--fast              Enable fast syncing through state downloads

This only downloads the blockchain and verifies the proof-of-work. It does not commit all transactions included in the blocks and therefore can be considered a pruned sync since not the whole state is recalculated.

After the blockchain was downloaded, the client requests the latest state-trie from other nodes and saves it. This is additional data, but this way you can synchronize faster and reduce the disk space requirements by around 80%.
