- n3t 3y agoExactly. What your parent described is a type of trusted timestamping and one doesn't need blockchain to implement it. [0]: https://en.wikipedia.org/wiki/Trusted_timestamping https://en.wikipedia.org/wiki/Trusted_timestamping
- NoImmatureAdHom 3y agoThanks--I didn't know the generic term.
- NoImmatureAdHom 3y agoYep, true. I can imagine cases where it is relevant, though. Like...something happens in the past, and people only become interested in it at some point in the future. For instance, Alice is accused of a crime that happened a month ago. There exists photo / video of Alice that is attested this way proving she hasn't committed the crime, and this is taken by Bob who seems to be an uninterested third party. It doesn't preclude criminal Alice from setting up this situation in advance given her intent to commit a crime, but it does seem to make it way harder.
