Blockchain IoT Foundations – Chief Scientist

I've been fortunate enough to attend the first meeting of what then became the Trusted IoT consortium, held in Berkeley in late 2016. The key idea was, combining properties of blockchain such as identity and immutable ledger with sensor data where provenance, authenticity, location, and governance are crucial for actions taken on the basis of the sensor data stream. It still takes an effort to wrap your mind around the way the two areas, Blockchain and IoT, interoperate. Various objects need to be ascertained as being something, belonging to someone, and being somewhere. One example is Supply Chain -- when a container is shipped from say Shanghai to Oakland, the buyer, the seller and the shipper all need to know, and to be able to prove, that it follows a certain state machine -- with loading, sailing, arrival, customs, and unloading, sequenced one after the other in time.
