Topic: Bitcoin-like network over bluetooth (Read 1775 times)

I think bitcoin should have failsafe backup connection incase internet collapsed when big things happen such World War triggered. New protocol doesn't depend on current internet infrastructure like Dash7 or near-field communications should be consider to implement on bitcoin network.

I thought of this peer to peer mesh network over bluetooth .It will be feasible in a scenario such as a class room or a any crowded public place, 30-40 people sitting in close proximity within the range of bluetooth(~10 m).Like shared usage of other devices software and hardware services.The main problem is that of routing algorithms as the units are changing position constantly one may join the mesh or leave the mesh at any time.

This potential is yet to harnessed .   

Just use this forum's search function and search for Dash7 or near-field communications.  I have written much on this particular subject here.  Otherwise just go to google and search for Dash7 and you should find all that you want to know.

As for the embedded devices and smartphones thing, it's coming.

Sounds interesting...


Could you provide me a link to this discussion?  I am very much interested in the scalability limits and minimum hardware/bandwidth requirements for bitcoin to 'work'.  If there were some way to proove that a functioning bitcoin client needs {some minimum hardware requirements} to function, that would be useful...  Ultimately, I would like to see bitcoin clients running as embedded devices inside smartcards, cellphones, etc.

Dash7 networking would work well for a general Bitcoin/smartphone network, as well as a great many other similar needs.

It has already been pointed out that 200kbs isn't fast enough for spreading a future full block (something that I would contest), but other methods of getting blocks are available to an Android based 'lightweight' client than just one digital radio.  If Dash7 radios become half as common as Bluetooth, such smartphones would be able to send text messages (modified Jabber)  even in a citywide blackout over great distances due to the natural propagation of 443 mhz combined with the ad-hoc meshing abilities of Dash7.  Bitcoin transactions could be spread far and wide, rapidly looking for a path to the Internet, using Dash7's "general broadcast message" mode.  Which would be heard by most Dash7 radios in a 2 klick radias of the sending smartphone, and be included into the transaction queue of every such smartphone that had a running Bitcoin client, to be further forwarded by those Bitcoin clients at every opprotunity.  Such a Dash7, or Dash7/NFC, smartphone owner need not have Internet access on their own phone in order to transact using Bitcoin in real time; but may need occasional access (via open WiFi hotspot perhaps) in order to keep their own blockchain up to date.  This means that said user would be able to spend coins that their blockchain already knows that they have at will, but not spend coins that were sent to them since the last time their client was able to update it's own blockchain.

Won't work.  Bluetooth on cellphone is no more than ~10 feet.

Like what?  I see no link or other references.

 Now we have Android on the way this could be much more feasible.

I think better to have a completely separate network this way than trying to shoe-horn Bitcoin into this. A completely new design. 

 The main difference here being the intermittency of the network.

However, such a network would be as interesting as Bitcoin because it would be completely separate from Bitcoin. In fact, it would be usable in places where there is no internet... or phone system.

 Have we heard of any attempts to make a cell/peer-to-peer/`mesh?` network over bluetooth like this?


The usefulness of such a network and the fact that this doesn't exist says a lot to me about how pervasive centralization is these days. Big opportunity to make changes here.
