 what will be done if quantum computers can compute the private key of the
 ed25519 master pubkey "of the hidden services". Large-scale/medium scale
 quantum computers would possibly be able to compute the private key of the
 master pubkey of the hidden service then they would be able to impersonate
 the hidden service.
