Witness data does not contribute to utxo set. The discount on storing
data in witness creates an incentive to store data exactly in the
witness and not in the parts contributing to utxo set.
$ du -sh blocks/ chainstate/
569G blocks/
9.3G chainstate/
Witness data is part of the "blocks" directory which is not
latency-critical and can be stored on a slow and cheap storage device.
Directory "chainstate" contains the data needed to validate new
transactions and should fit into a fast storage device otherwise
initial block download takes weeks. It is important to maintain the
incentives structure, resulting in a small chainstate.
