Do you mean something like Blockstream Satellite (https://blockstream.com/satellite/)?

I think this is the thread you mentioned
https://bitcointalk.org/index.php?topic=1532466.0

There was some talk about that a while ago, here is an article I was able to find
https://www.rtl-sdr.com/receiving-the-bitcoin-blockchain-from-satellites-with-an-rtl-sdr/

And one more...

And at least I was first to the idea

Not even remotely.

Proof? :)

16:25 < gmaxwell> Eliel: If you can raise about a grand a month I'd be glad to run a satellite blockchain feed that can be recieved by fairly inexpensive hardware.

08:53  * cjd thinks the future holds someone leasing a satellite transponder and any tx which pays him a few thousand satoshi gets pushed to the satellite and bcasted to thousands of nodes simultaniously.
08:53 <@gmaxwell> cjd: So I've gotten quotes in sat bandwidth, it's pretty cheap if you don't want much.
08:54 <@gmaxwell> cjd: at least for capacity on C-band transponders.
08:54 <@gmaxwell> Yea. :( well, its easy, but you need either a bigger antenna or low data rate.
08:55 <@gmaxwell> cjd: with a big (1.5m) antenna I can easily bit the blockchain in a 10KHz channel that costs only $50/month.

10:12 < gmaxwell> And if you want to think ahead, it's quite easy to broadcast blockchain updates via satellite... and it only takes on transciever to heal the network in a disconnected zone.

14:03 < gmaxwell> jgarzik: Old C-band sat bandwidth is not terribly expensive.  I got a quote a while back for $350/month for 100KHz bandwidth on a bird that should be visible to all of north america, central america, and some of south america.
14:04 < gmaxwell> and 100KHz is wide enough that you could fit the blockchain maxrate there with low order modulation and lots of FEC and hopefully pick it up with a fairly small dish even though its cband.

12:04 < gmaxwell> bandwidth on old C-band geosync sats  is cheap... we could be brodcasting the blockchain for <$100/mo.  Antenna is pretty big though.
12:04 < gmaxwell> Bandwidth on stuff that can use a small antenna is more expensive, alas.. though I've never gotten exact quotes on it.

I still want to know if there’s a 2 way system for this, if not it’s pretty redundant,

Here are a few randomly selected public IRC discussions about satellite transmission of Bitcoin data.


But hey, if you want to take credit for suggesting something that we'd been discussing for at least 4 years and had even started to implement before my post, knock yourself out.  That isn't half as crappy as wishing you'd patented it and thus actually gotten in the way of anyone actually doing it...

Kinda sad that you claim to have come up with it but seem to not get the point.

Two way isn't all that that interesting, relative to the complexity/economics of it: There are 1001 ways to send a transaction.  There are commercial two way sat internet services-- they charge by the byte and would cost about $50k - $150k per month to get the blockchain streamed,  but only cost cents for a single transaction.  You can send single transactions by SMS, you can send them on QR codes printed on postcards.  You can send them along with the order you make to the party you're paying however you are doing that, etc.

A 2 way service is essentially what I’m questioning here and whether it’s at all possible to do (also, a way to buy something that’ll connect to those block stream satellites would be good too :) ).
