There is absolutely no reason that the networking equipment itself can't
both operate the blockchain and keep a full copy. It's a pretty good
bet that your own routers will probably be online;Â if not, you have
bigger problems.
The storage requirements aren't particularly onerous. The entire
Bitcoin blockchain is around 150GB, with several orders of magnitude
more transactions (read: config changes) than you're likely to see even
on a very large network. SSDs are small enough and reliable enough now
that the physical space requirements are quite small.

You (presumably) trust your own routers. There is absolutely no reason
that your own little network can't run your own private blockchain.  In
fact, for my use case of configuration management, you wouldn't WANT to
use a single global public blockchain.
