Kryptoradio – Bitcoin broadcasting tool and more!

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

The Bitcoin serialization tool must be connected to a trusted peer (a
bitcoin node run by yourself) because transactions and blocks are not
verified to keep this tool as simple as possible without compromizing
security. For information about the Bitcoin part, see subdirectory
bitcoin/.

The data stream produced by kryptoradio-encoder uses PES packet
format that is compatible with DVB encoder hardware.

See our project page for a
longer description.

How to just hex dump the traffic

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

How to install and use Kryptoradio receiver

See receiver/.

How to compile broadcasting components

You may safely skip this if you want to just receive Kryptoradio. Here
are 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-dev
cabal update
cd encoder
cabal install
cd ..
cd data_sources/exchange
cabal install
cd ../..

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.
