&gt; throw a beefy server at the list of transactions, and since you know how much money arrived in someone&#x27;s possession on a given date, you can now trace it backwards by crunching the numbers.<p>I hope you realize that you haven&#x27;t actually described a process for tracing Bitcoin transactions. You can&#x27;t just take an arbitrary problem, say &quot;throw a computer at it&quot;, and consider it solved.<p>I don&#x27;t mean to be abrasive, but you are clearly ignorant of the state of affairs of Bitcoin anonymity systems. Look up coinjoin, for starters. When you have highly-connected (in the graph sense), properly conducted mixing systems, you can&#x27;t just &quot;trace the transactions&quot;.
