Have a look at the <a href="https:&#x2F;&#x2F;ethereum.org" rel="nofollow">https:&#x2F;&#x2F;ethereum.org</a> project to see how this could work out. If these kind of distributed systems for messaging, data distribution and storage as well as consensus scale, intelligent agents will be able to interact with services and each other faster, efficiently and more secure than before.
