#BlockstreamSatellite

If #BlockstreamSatellite wasn't using #cringe #Bitcoin but #Monero it would've been a cool idea for an #anonymous #messaging system...

Anyone know who to talk to at #SES / #Intelsat and/or #Eutelsat to get #narrowband #SCPC (or #MCPC for Audio / #Radio bandwith)?

  • Cuz I imagine something like that wouldn't be that expensive given that it's like easy to mux & demux and requiring less bandwith than an actual TV or radio station broadcast...

OFC people will rightfully point at #IridiumBurst ¹ and #Iridium #SBD² but those require #subscriptions³ & expensive, custom devices and whilst in turn one can send free #SMS to #Iridium devices, those are limited to like 50 and one can't use a nice #API to basically make them.

Cuz a C-band mesh reflector & LNB is at least feasible to obtain and setup in most places that have no Internet.

Blocksteam Satellite's Page showing it's coverage, which beyond the EU, USA, West Afica, China, India and Japan seems to be lacking.

Notably not covering big chunks of the Middle East, Central Asia, Russia and the entirety of South America south the Darien Gap.

It would've been a way better coverage area if it used solely C-Band Global Beams.

@dbread @ticho @delta @torproject Seriously, I'd rather use #CryptoBro stuff like #BlockstreamSatellite ¹ to message people because it's cheaper than #IridiumBurst² and doesn't require them to have a contract & expensive device or me know their #IMEI and coarse location.

@adisonverlice I mean, I could see something like an #IrDA or #BLE / #WiFi thingy that basically exchanges packages kinda like a bulk delivery that one just slaps onto a device.

  • Kinda the #DataMule idea some folks suggested to do with like( informal) (mini)bus services in the global south to get large amounts of data to areas that have no internet or only slow narrowband connectivity at best.

A ground-based alternative to #BlockstreamSatellite would be kinda cool espechally since they use #Shitcoin (#Bitcoin) and transfer of data is just absurdly expensive by pricing.

On May 31 at 12:00 UTC we will update the #BlockstreamSatellite frequencies used on Telstar 11N (T11N).

This update will affect both the Europe and Africa beams, so users in those regions must upgrade to keep receiving the signal.
