Thanks for clearing that up.
It seems to me that this is a very fragile solution - as you are well aware, most users would lack the technical sophistication to kept such receipts safely (eventual data loss being my main concern here), which really only leaves the hosted wallet option.
I am inferring from the information that you have provided so far that it is game over if the user loses the receipts?
In that case, all of the user's balances are one third-party-company-going-away step from the void.
It is possible (quite possible, in fact) that I misunderstood something, but if the picture I painted above does match what the technology can do.. then I don't see how even someone technical like me could get the warm fuzzy feeling (tm) using this technology..
In timeless words by timeless people.. sh.t happens.
Yep. Fortunately, you could also store an encrypted receipt on the blockchain using a
customoperation. It would just end up being slightly more expensive to store them on-chain. It's not like there aren't cool solutions to that 'storing' problem. Not having that problem would be nicer though - of course.Well, if you manage to secure the private keys for your accounts, you should be able to do so as well for receipts. You could easily store them next to the wallet of private keys in your browser (though that would require regular backups instead of just a single backup) - but I (and probably also Dan) agrees that the storage problem in the STEALTH solution is somewhat delicate.
Shit doesnt need to happen. Thats just a poor excuse. Why does security continue to be the bottle neck for many of these crypto currencies.
