Each offsite copy of git repository will give alert then, as all hashes in chain changed at some moment. Same principle as blockchain. On 2018-01-08 09:54, tglassey@earthlink.net wrote:

better than plain old PKI. that in computer networking?
Regards, Bill Herrin There's probably some potential in using a blockchain for things
configuration management. You can authenticate who made what change and when (granted, we can kinda-sorta do this already with the various authentication and logging mechanisms, but the blockchain is an immutable, permanent record inherently required for the system to work at all).
That immutable, sequenced chain of events would let you do things
"make my test environment look like production did last Thursday at 9AM" trivially by reading the blockchain up until that timestamp,
Or when you know you did something 2 months ago for client A, and you need your new NOC guy to now do it for client B -- the blockchain becomes the documentation of what was done. We can build all of the above in other ways today, of course. But
running a fork of the chain for the new test environment to track its own changes during testing. there's certainly something to be said for a vendor-supported solution that is inherent in the platform and requires no additional infrastructure. Whether or not that's worth the complexities of managing a blockchain on networking devices is, perhaps, a whole other discussion. :)
- Peter Why to reinvent git? :) Lot of tools available also, to see diff on git commits, to see who did commit, and what exactly he changed. (it is possible to cryptographically sign commits, as well, and yes,
