The major disadvantage of all cryptocurrencies versus cash is that without connectivity, they are all completely fucking useless, and therefore worthless.
Can we solve that with Masternode mesh blockchain technology?
I think this should be made to exist. Anyone here know much about crowdfunding?
Darkcoin. Private. Instant transactions. Works on Mars*
*space/underwater/middle of the ocean/up Everest, if you have a wireless router running a MN onboard your spaceship/submarine/ocean liner/sherpa.
This would be like a perfect dream.
There have been some talks on the subject elsewhere (Can bitcoin survive without the Internet?, Nick Szabo: "Reliable & secure P2P broadcast crucial to block chain protocols. Radio more secure than simulated broadcast on Internet.", and [BitPool] Mesh networks to bypass ISPs, for example) and although this seems to be a very important subject no final solutions have yet been brought up.
The point is that in case of a major Internet failure (caused by wars, natural disasters, corrupt governments, etc) the blockchain would become "hostage". The idea is to have a "backup network" in wich Darkcoin could function: An indepentent mesh network to coexist running in parallel with the Internet, but with its own infrastructure.
Maybe the Masternode technology will finally make it possible.
Thanks for the links.
DrCrypto on DCT brought up a good problem: in the case that someone else on the 'main' network also has access to the funds in a wallet, they could be double spent on the 'main' and 'offline' networks. Kind of a fringe case but no answer to it has yet occurred to me.
