This repositery contains zkSNARK implementation in ZoKrates to prove in ZK signed GPS locations

Follow the instruction below to setup ZoKrates and ZoKtrates pyCrypto library to generate signed GPS data hashes

Install ZoKrates

check https://github.com/Zokrates/ZoKrates

be sure to have zokrates binary available in your $PATH be sure to set $ZOKRATES_HOME properly

Make sure you are running a python 3 runtime.

git clone https://github.com/Zokrates/pycrypto.git
pip install -r requirements.txt

End-to-end example

./generate_powha.sh

#generate hashes for geodata the generator script works with Python2, there is a problem with geohash library in Python3 (vinsci/geohash#4)
