Token Standard of Product Crowd Sale

日置玲於奈

For the sake of consumer protection in blockchain industry, we propose this token functions “Advanced NFT” as a login system & blockchain-account system.
In this systems, one Non-Fungible Token proves one license of a software, and enables the holder to login/use it. Simply, holder = user.

(1) First of all, Advanced NFT has an additional public key attached to itself.

It’s called “subkey”.
To login, a signature of this subkey is required.

(2) A subkey and its private key can be generated from a password safely.

So user can use password to login the software, and can easily backup it as a private key. So there’s no need of wallets to login.

(3) Account of blockchain own NFT.
