Finnish National TV Broadcaster Starts Sending Bitcoin Blockchain 73

New submitter Joel Lehtonen (3743763) writes "The Finnish national digital TV broadcaster Digita is co-operating with startup company Koodilehto to start transmission of Bitcoin blockchain and transactions in Terrestrial Digital TV (DVB-T) signal that covers almost the entire Finnish population of 5 million people. The pilot broadcasting starts September 1st and lasts two months. The broadcast can be received by a computer with any DVB-T adapter (like this $20 dongle). A commercial production phase is planned to begin later this year."

    So how precisely is this useful? It allows both Alice and Bob to confirm Alice indeed sent X BTC to Bob. But if Alice is going to send Bitcoins to Bob anyway, then she need to have some means of uploading the details of her transaction.

      The point of the service is you can use cheap and small receivers on embedded systems to confirm transactions, for example for vending machines etc. The mobile internet coverage is not as wide as radio signal, nor is it as cheap.

        If there's no internet coverage, how does the customer make the transaction ?

      The blockchain is big, and it's the same for everyone, so broadcasting it is efficient. It also has the benefit of giving everyone a view of the blockchain that is independent of the individual position in the network, which could make some attacks more difficult.

      The summary was quite lacking. For those not wanting to rtfa, here's what it says under why broadcasting the blockchain in a way that can be picked up by low cast receivers is or might be useful. An AC post below also mentions that TV coverage may be better than mobile internet coverage.

      This scheme makes it easy to construct affordable receivers that do not need mobile data connections in order to follow bitcoin traffic and to react to the received bitcoin payments. This would make it possible to build bitcoin counterpart for cash payment terminals, anything from a cash register to a coin operated self-service laundry. If the receiver application follows only transactions relevant to itself, it will be possible to build it using even an ARM microcontroller.

      Also, it allows an alternative way to access the bitcoin network in cases where only a very low speed Internet connection is available. And, for all the tin foil hat wearers out there, this is a way to connect to bitcoin network without a trace! You only need online access when you want to make transactions yourself.

      The data stream can contain other information, such as exchange rates between bitcoins and traditional currencies.

    Finnish TV sending money over the airwaves to their customers? :-)

    BTW I had a Scandinavian girlfriend at some time, but I don't know exactly which country she was from, but definitely not from Finland, because each time when we were having sex, she yelled: No, no, I'm not Finnish!
