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:

But there's certainly something to be said for a vendor-supportedsolutionthat 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 wholeotherdiscussion. :) > - PeterWhy 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, they are chain signed, as "blockchain")
