> "These two things don't seem to obviously go together." That actually makes a lot of sense: if you consider some of the security challenges associated with IoT, e.g. an IoT door lock, then a smart contract where you have m of n signatures needed to unlock it (think of them like a modified escrow with policy side, too), then you can see the play here. The transaction to open the door gets signed only if that policy is met at each of the m signatures. You might have a lock device signature, a home signature, and a home owner signature. There are lots of microtransactions in IoT (good and potentially bad). Smart contracts can mitigate / isolate risk and ultimately reduce attack surface vulnerabilities. Block chain is a necessary part of this to work. For more info check out "bitcoin 2.0".
