Abstract
Methods and systems for authorizing transaction requests from user device based on blockchain asset-based access control rules. A server receives a digital signature from a user device and independently generates the message that was signed by the user device. The user device does not send the public key. The server derives the public key from the message and the digital signature and then queries the blockchain network to confirm it corresponds to a valid wallet address. The server obtains ownership data associated with the wallet address from the blockchain network and, based on the ownership data, determines whether to authorize a requested transaction.
