    1. Okay, so what’s the blockchain? It’s a database. Unlike most databases, it’s not controlled by one entity and it’s not easily rewritten. Instead, it’s a ledger, a permanent, examinable, public database. One can use it to record transactions of various sorts. It would be a really good way to keep track of property records, for example.

These devices need to be resistant to hacking. They need to be able to communicate value such as money or assets like electricity, peer-to-peer. Consider electricity, if you imagine that your neighbor's home is generating energy from a solar panel and you've got a device that needs to buy that electricity, then those two devices need away to be able to contract, bargain, and execute a payment peer-to-peer.
