Fascinating idea. In the areas that this would work, would it not be simpler to just use a normal cell phones data connection or SMS?

- pronoiac 12y agoSay the blockchain's growing by a gigabyte a month.[1] I don't think SMS can support that much, especially times so many devices. Using a tv signal is more robust - you can support millions of devices, and transient 3G network failures will have less or no effect.

- zouppen 12y agoIf you stick to centralized solution then that would work nice and might be good enough. However Kryptoradio allows to do it by just listening incoming transactions and blocks.
