Claim 19:
20. The blockchain system of claim 18, wherein, on condition that the processor, via the address abstraction smart contract, has registered the externally owned account corresponding to the user identity as the user blockchain identity by performing the third process, and
in response to receiving the transaction registering request including the transaction message from the user terminal, at the process of (I), the processor, via the address abstraction smart contract, instructs the user terminal to generate the user identity corresponding to the user certificate, and
in response to the user terminal transferring an executable transaction including the user identity and the transaction message to a specific blockchain node on which the executable transaction is to be executed and in response to the address abstraction smart contract receiving a verification request for the user identity from the specific blockchain node, at the process of (II), the processor, via the address abstraction smart contract, (i) verifies whether the user blockchain identity corresponding to the user identity included in the executable transaction exists and (ii) when the user blockchain identity corresponding to the user identity is confirmed to exist, transfers the transaction message to the blockchain network so as to be executed and registers an execution result of the executable transaction on the blockchain network.
