The aim of this project is to create a toolset for broadcasting datato DVB-T and receiving it. It uses Kryptoradio protocol and issuitable to all kinds of low bandwidth data. The main use case isBitcoin broadcasting over digital television.

The Bitcoin serialization tool must be connected to a trusted peer (abitcoin node run by yourself) because transactions and blocks are notverified to keep this tool as simple as possible without compromizingsecurity. For information about the Bitcoin part, see subdirectorybitcoin/.

The data stream produced bykryptoradio-encoder uses PES packetformat that is compatible with DVB encoder hardware.

See ourproject page for alonger description.

While the receiver tool is still under development there is a hex dumper tool available in the source tree directoryscripts/dump/. Happy hacking!

You may safely skip this if you want to just receive Kryptoradio. Hereare very brief installation instructions for broadcasting components:

sudo apt-get install cabal-install libghc-aeson-dev libghc-blaze-builder-dev libghc-cmdargs-dev libghc-http-types-dev libghc-stm-dev libghc-scientific-dev libghc-text-dev libghc-wai-dev libghc-warp-dev libghc-websockets-devcabal updatecd encodercabal installcd ..cd data_sources/exchangecabal installcd ../..

The resulting binaries are~/.cabal/bin/kryptoradio-exchange and~/.cabal/bin/kryptoradio-encoder.

Even if you don't have the hardware you may run the encoder in "mock" mode. Ask me for help.
