   but personally i support keeping ancient utxo logs because it means
   people in trouble can store their experiences and evidence in the
   permanent logs.

   ....

   USPS doesn't keep the history record as other blockchains, removing the
   immutable trait, which I consider dangerous for privacy.
   At the same time people can store their evidences and make them
   available or delete them if that is convenient.
   It's a pity that USPS is being overlooked.

   USPS sounds important.  One thing we consider when protecting
   information on security lists is the problem of "rubberhosing" -- being
   physically forced by someone else to remove the security from the
   information, to keep your own life, health, or livelihood.  Hence a way
   is needed to protect crucial information from deletion _even_by
   its_owner_.  But you've probably heard this already.
