Bitcoin’s Latency–Security Analysis Made Simple Northwestern University University of Illinois at Urbana-Champaign Copyright By PowCoder代写 加微信 powcoder non-lockstep synchrony model [6, 10–12]. The fundamental fault tolerance limit of the Nakamoto consensus has also been obtained [2, 4]. Most existing latency-security analysis of the Nakamoto consensus focused on asymptotic results. This means they showed that transactions
