There have been schemes for trusted timestamping (e.g. based on PKI) around for a long time: https://en.wikipedia.org/wiki/Trusted_timestamping NB Having worked in the area I find document security (particularly authenticity) to be a fascinating subject and its not inconceivable that a blockchain based solution could be interesting but I'd love to see how such a thing would actually work in practice and some kind of idea why it is better than earlier approaches. "because blockchain" isn't really an argument. |
