08:42:30 Hello. I am interested in timestamp proofs using monero. 08:42:31 After reading a bit here and there, the best approach I have found is the following: 08:42:33 1) Suppose I have a 256bit secret `S` 08:42:35 2) Create a new wallet with `S` as seed, say with public monero address `A` 08:42:37 3) Send some XMR to `A`. The transaction is included in the blockchain and thus has a timestamp. 08:42:39 4) Eventually disclose `S`. Anybody can verify that `A`, generated from `S` has received some XMR at the given date. 08:42:41 5) [...] of course the XMR in `A` will now be stolen by somebody. 08:42:43 Is this the best approach to the problem? Any other ideas? 08:45:19 makkiato: hi. What level of accuracy & precision are you looking to achieve? In [4] you mention "given date" - is that all the accuracy you require? 08:49:31 neac: hi! Yes, since the timestamp I am looking for is a blockchain block, I guess the precision is indeed quite limited. But yes, +/- 1h is what I am thinking about at the moment. 08:49:33 I am basically thinking about something like opentimestamps.org, but simpler and homemade, and based on monero. 08:49:35 One variant of the above "protocol" would to use `S` to generate the private view key only, and use a random private spend key. This way we fix point (5): after release of `S` everybody can view A but not spend its xmr. 08:51:12 Sounds interesting. 08:51:13 (Although this isn't the ideal forum for such discussion, really. Perhaps consider moving it to https://matrix.to/#/#monero-research-lounge:matrix.org?) 08:52:02 Thank you, I did not know that channel. I will move there :)
