Conclusions

Let's think about killer application that target mass markets outside of crypto. What could those be? Ideas?

TLDR. I want to be able to hand someone a crypto currency token and want them to trust that the value is on it, and I can't spend it behind their back.

THIS IS AN OLDER IDEA, REPLACE THE OLD NAMES WITH THE NEW ONES

"interesting. it will be pretty tricky to make sure a transfer is valid (ie no double spends), however there should be some way to use hashing, multisig and encryption to enable this.

not sure about the fiat side of things (regulations), but at some point this would make it much easier of people to adopt crypto. making possession of it trump any hidden copies is the key. there might be some research about this already, my guess is that it will need to use zero knowledge proofs"

"Interesting, I like the idea of real world connections to crypto, will need to think more about this one.

I think you should look into NFC as your communication method or maybe clever QR (address on outside private key on inside fold) this would be much cheaper while still having the same type of effect."

MICRO MONEY rev 2

Is intended to be a Micro SD Card wallet technology to help facilitate Off-Blockchain transactions. This would allow various crypto types and amounts to be put on a normal or custom printed Micro SD Card to be holdable, tradeable, refillable, and collectable.

WHY:
Right now paper money is a wonderful anonymous tool. Unfortunately paper money cannot be sent through the Internet. Micro Money is an idea to combine tangible currency with Internet capabilities as well as provide an easy to use crypto-coin container for the public.

For the general public it is easier to understand harder concepts like crypto currencies if it is tangible and you can hold it in your hand. I also wanted something more dynamic then a paper wallet or a non electronic collectible wallet token. And I've observed that humans love to collect miniatures, whether they are micro-machine toys, DnD figurines, doll houses, train sets, models, muscle men, gi joe, etc, etc, etc. Basically this is cool, fun, and something I would not mind owning and I hope others would as well.
(DISCLAIMER: This is not intended to be a replacement for the trezor or other similar wallets but a functional, secure method that promotes off-blockchain transactions.)

I envision it working something like this:

HOW it works for the user:
1.The user obtains a Micro SD Card, regular off the shelf or custom printed with coin logos.
2. The user inserts the card into a reader.
3. The user loads the SuperNET wallet and selects the Micro Money app.
4. The user selects the type of crypto to load and the amount from the wallet.
5. The app then loads that amount onto the card. (The app only allows one value per card to be added)
6. The user can now remove the card for trading or storage.
7. If the user wishes to verify the balance on the card it is held near a NFC device to verify.
8. If the user wishes to spend the value on the card it is inserted, and transfer/spend is selected and it is transferred by the wallet. (The Micro Money card is now empty at this point and ready to repeat step 1.)

HOW it works for the app:
1. A new Micro SD Card is formated per the app. (A partition is setup)
2. If possible one of the partitions is hidden.
3. The app generates wallet keys for the type of crypto selected.
4. The value selected by the user is transferred to this new wallet.
5. On the hidden partition, a hash of the private key and a hash of the public key is created.
The idea is to not make it easy for the public to know either key so the value is effectively locked to the card.
6. To prevent double spends the wallet keys should be un-viewable and/or un-retrievable by the user in the app and the wallet.
7. To verify balance on the card, the app uses NFC and translates the public key hash and verifies balance.
8. To spend/transfer from the card the app translates the private key, moves the value it contains, then deletes the keys. The user now repeats step 1.

This is an excellent idea! It helps brake down the barriers of exchanges and what some people have called crypto; "pretend money" Don't see any technical barriers but, lots of marketing and education would be needed. Does it make sense to redirect current development & marketing initiatives to something like this?
