AWS and Blockchain
Blockchain was invented to solve one particular problem: distributed consensus on a sequence of transactions, where the choice of which transaction to include from a set of conflicting transactions is irrelevant.<p>The latter property here is key to understanding where blockchain is useful. It was created to solve the &quot;double spend problem&quot;, ie. two transitions that spend the same coin but send it to different recipients (and so they conflict and cannot both be included in the canonical list of transactions). A double spend is the result of the sender either (a) making a mistake, or (b) attempting fraud. In both cases the important property is that as long as only a single of these conflicting transactions is included, the systems works.<p>Only if your problem exhibits the above property (<i>and</i> it&#x27;s a distributed system) does using a blockchain make sense.
