I had a look at your idea and I must say that I'm impressed with it as it does give MOIN a use case and also can be used as added security on websites. We haven't heard from KingCaper in a while so hopefully we get an update from him soon and get his opinion on this idea as I'm all for it.
Thanks, I think as the idea develops it could be refined, but the core concept it's good. Yes, it could be used as an alternative to google authenticator or email/text based authentication. I think multi-factor authentication could be a unique feature too, which would require multiple user addresses to be confirmed before access is granted.
From a coin supply perspective, current supply is 9 million with a total of 21 million, so assuming the 2FA project got mass adoption, we would likely have to ensure there was enough going around to maintain usability. I am also unsure if the coins sent for Authentication should be burned or sent to a central wallet for MOIN development. We can work out the details later though.
Beyond this, there are some key things I'd love from a MOIN project wish list. Effectively, a real privacy based eco-system.
- Mobile wallet storage
- Mobile encrypted chat (in-wallet private / group chat)
- The ability to sync a mobile and desktop wallet / chat
- Two-factor authentication (as described in image)
- Multi-factor authentication (similar to 2FA but requires 51% (2+ more people) of specified addresses to approve access
- Cold staking
- Hardware wallet storage
Well I think it can work even with the current max supply as the dev could just lower the amount of MOIN needed for authentication and also depending on the price it can be lowered or increased. I believe I mentioned cold staking in here a while ago as I think its another good way to stake and I have seen several projects do this and have had great success with it.
