Blockchain is no better at transferring log files than regular PKI.

Blockchain could be used to authenticate that forensic evidence presented
later is the same evidence that was originally logged by the individual who
collected it where the agency responsible for custody of the evidence is
not trusted or where there have been claims evidence tampering. Interesting
law enforcement application. Dubious utility in networking where the
networking staff are a trusted authority.

AFAICT, blockchain is no better at this than regular PKI and regular PKI is
much less expensive to operate.

That's not obvious to me. Assuming the time-exceeded message was modified
to include the necessary data, how would blockchain authenticate the
responding router?
