MetaAuth

MetaAuth - An on-chain OTP generator and authenticator, providing enhanced security by granting ownership of OTP to you. Hundreds of thousands of on-chain properties were stollen because of ungranted operation, unauditted contract codes or false security overriden protocol. We propose a new authentication protocol named MetaAuth, which generates and verifies OTPs on blockchain systems. We can provide enchanced security by granting the ownership of OTP to yourself, where nobody can make decisions without your permission.
