M9 Uplink
Authentication
BitSat B1 uplink notes SHALL send bitcoin blocks in a reliable, digitally authenticated data envelope to satellite

would it have been possible (or desirable) to design the sats in such a way that anybody would've been able to connect to one of them and send it a block?

You may know issues on mining, according to your one paper, these satellites generate 18.5 W of electricity, also cooling is a big issue without water & air outside the atmosphere.

Whatever the benefit beside geekness will be, looks like only proof of stake can run fully independent in space.

What about experts from universits ? Maybe they can help with it too, but I am not sure about that investors, can kickstart help us ?

Are there any basic specs for the satellites up anywhere ... just would like to know some basics, dimensions, weight?

More than just basic...

Check out DunveganSpace.com for one-page info sheet + 93-page design specification.


cool, thanks.

ps: Lagrange, as in "Lagrange points", is one word, named after Joseph Louis Lagrange mathematician/dynamicist who discovered those points.

What about a system where the Block chain is carved up and stored on people's PCs in smaller chunks, actually, they are probably working on this already, a bit like i2p

Imagine that they are already a couple of BitSats up there, how the average Joe uses them?

Joe has modern a android device (i.e. nexus 5) and a average laptop.

A satellite receiver.

The project specification indicates that the receiver should be made with Common, Off The Shelf (COTS) parts, and may be purchased or built by a skilled hobbyist.

Ireland's RTE Long Wave radio station on 252kHz is to close down this January.  That's 18kHz of bandwidth that could cover all of the British Isles and reach all it's 68Million people from a single transmitter.  Plus I'd imagine that Northern France and maybe the low countries could also receive the transmission.  The blockchain plus a Digital Radio Mondiale coded audio station could be broadcast with the 18kHz of bandwidth using the Digital Radio Mondiale codec.  Or more data like alternative blockchains could potentially be transmitted instead.  LW transmissions have good penetration into large buildings.  So an external antenna on the outside of the building would not be needed.
Yes.  Ideally blockchain data, plus other useful data, can be transmitted if bandwidth is available.  For example, the next probable goal for transmission would be live bitcoin transaction data.  This enables mining (assuming you have an uplink somewhere), by delivering a "full feed" of bitcoin protocol data.

After blocks + TXs, there are plenty of other useful things one can imagine.

With the full 18kHz of bandwidth at 252kHz LW it looks like you could potentially transmit up to ~25kbps (Mode D) to ~60kbps (Mode A) using the Digital Radio Mondiale codec.  So almost 11MB could be transmitted per hour in Mode D.  Or about 1.8GB per week in Mode D.  Which is about 94GB per year in mode D.

Kryptoradio are broadcasting blockchain data in a 7.5kbps channel on the UHF band using the DVB-T1(or possibly)T2 codec in Finland.  Using the Digital Radio Mondiale codec you could broadcast =>7.1kbps over a 5kHz channel on SW/MW/LW.  Although renting SW transmitter broadcast time costs around $25k per month for 24/7/365 broadcasts.  5kHZ though is about a quarter of the bandwidth that current AM radio broadcast stations use on MW or LW.

The three links in the OP are not working for me?

Fixed.  Thanks for pointing that out.

Some things got moved to BitSat.org.
