A Bitcoin system with no mining and no history transactions: Build a compact Bitcoin system

Abstract

We give an explicit definition of decentralization and show you that\ndecentralization is almost impossible for the current stage and Bitcoin is the\nfirst truly noncentralized currency in the currency history. We propose a new\nframework of noncentralized cryptocurrency system with an assumption of the\nexistence of a weak adversary for a bank alliance. It abandons the mining\nprocess and blockchain, and removes history transactions from data\nsynchronization. We propose a consensus algorithm named Converged Consensus for\na noncentralized cryptocurrency system.\n
