摘要

A computer implemented method of updating a database system for a blockchain version control system, including a smart contract version control system, wherein proxied smart contracts each refer to a single centralized version controller smart contract which contains an index of smart contract logic code addresses, the method including the steps of: (i) updating a smart contract logic code addresses in an index so as to update the proxied smart contracts, and (ii) updating the database system for the blockchain version control system, to reflect the updating of the smart contract logic code addresses. There is further disclosed a computer implemented method of auctioning an item for a seller.
