&gt; Bitcoin&#x27;s computation does the job of securing the blockchain by forcing an attacker to spend computation cycles to match up the computation done for these hashes.<p>So we could call this approach to scaling communications, &quot;brute-force messaging&quot;?  (..since it also forces anyone who wants to enlarge its available message space to pre-compute hashes ...with an ongoing race condition, so &quot;raced, brute-force messaging&quot;?)  Scaling seems a bit off though, since its design enforces &quot;expensive, frantic scarcity&quot;.  That seems rather limited for a growing population&#x27;s needs for communications around an increasingly valuable resource base.
