If I have a NFT concert ticket, how do I get into the concert? What do the people at the gates do to determine that I may enter?
Do I print a piece of paper? Do I show them a picture on my phone or something? Can't the previous owners of the NFT show the same picture? Can't anyone show the same picture on their own phone?
You hold the ticket on a wallet on your phone, then you scan a QR code at the door that prompts you to sign a message from your wallet. Signing a message is instantaneous and verifies you control the key that owns that ticket.
No infrastructure in venues integrating NFTs but it’s no different than a traditional ticket.
Your NFT could have an associated QR code read at the door. In case of conflict there’s only one owner with access to the associated wallet and will be able to proof ownership via app / website…
Someone could make an app that only shows a QR code for NFTs you own. Someone else could make an app that shows QR codes for NFTs they don't own.
I suppose your right that it usually wouldn't matter, but in case of conflict you better be prepared to sign something with your private key. If NFTs make most of society familiar with public and private keys, message signing, etc, it will be a win.
A QR code is a number too and not a very large one. Small enough I think to fit on-chain in the tokenURI field of an ERC721 contract. Not eve need of ipfs or arweave to store an image.
Yep, if someone else tries to access with your ticket you can always sign with your wallet somewhere to resolve the conflict.
We will probably see crypto wallets integrated in our phones and associated OSs pretty soon to make everything smooth.
I don't think that will work. My public key is public. The ticket's public key is public. Right?
Thus, anyone can make QR codes that show the 2 public keys. It's trivial. This is the "showing a picture" scenerio I mentioned above. Anyone can show the right picture, especially since the picture that needs to be shown is public information.
