US Patent 11019059 Blockchain-based admission processes for protected entities

A method and system for blockchain-based access to a protected entity are provided. The method includes granting access tokens of a first-type to a client; identifying, in a blockchain network, a conversion transaction identifying a request to convert the first-type of access tokens with access tokens of a second-type, wherein the transaction designates at least the protected entity; determining a conversion value for converting the first-type of access tokens into the second-type of access tokens, wherein the conversion value is determined based on at least one access parameter; converting, based on the determined conversion value, a first sum of the first-type of access tokens into a second sum of the second-type of access-tokens; and granting the client access to the protected entity when the sum of the second-type of access tokens is received as a payment from the protected entity.
