Former radio amateur Jeff Garzik ex-KB4UZB plans to develop a CubeSat BitSat to distribute block chain data for the digital currency Bitcoin.

Jeff’s amateur radio license expired in 2006 and in recent years during his spare time he has been a Bitcoin core-developer, contributing to the core Bitcoin protocol.

He says that a satellite node could help defend the Bitcoin network from a Sibyl attack, which is where malicious computers flood a node on the peer-to-peer network with bad data.

It is reported that so far he has raised 37 Bitcoins (about $32,000) in funding for the project.
