Blockchain for IoT: A Big Idea Meets Hard Design Questions – CoinDesk
One of the most ambitious ideas in blockchain is that the technology could enable not just people and businesses to transact with each other seamlessly, but also machines.
If this scenario, first articulated a few years ago, comes to pass, devices ranging from refrigerators to automobiles would not only collect and share data as part of the emerging internet of things (IoT), they would also be endowed with cryptocurrency wallets and unique, blockchain-based identities.
The business possibilities from this physical internet of value are vast, potentially expanding the transactional economy in once-unimaginable ways. Self-driving cars might pay each other to cut ahead, for instance; a fridge equipped with sensors would know when it’s running low on milk and zap the grocer some crypto to deliver a fresh carton.
