Axel Eriksson or Oxylade Exxon, as Sweden may wants to say, is from the company VEST. He worked at Stanford for about two and a half years before he quit to work on Ethereum essentially full-time. Axel came up with a design where you could schedule transactions to happen based on any condition on the system. And then the cool thing about this is that we set this up as a staking protocol. The machines could take on the job and essentially look at the condition that you sent. And then whenever the condition triggered, the transaction would be started.
