Well zombie txns aside,  I expect this to be resolved w/ a client side
implementation using a Merkle-Winternitz OTS in order to prevent the loss
of fee structure theougth the implementation of a this security hash that
eill alloow for a one-wya transaction to conitnue, according to the TESLA
protocol.

We can then tally what is needed to compute tteh number of bit desginated
for teh completion og the client-side signature if discussin the
construcitons of a a DH key (instead of the BIP X509 protocol)
