IBM is using the ethereum block chain protocol to transform the IoT. They are calling their project ADEPT (Autonomous Decentralized Peer-to-Peer Telemetry). You can find the video of their demo at CES here
and a comprehensive overview here
Its really great to see larger companies adopting the block chain. It seems like an inevitable progression.
I get the impression that DPoS is great for the coordination of human action but not as appropriate for the coordination of machines. How does the bitshares block chain protocol fit in the context of IoT, if it all?
