Quick start

Install dependencies

sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum solc

git clone git@gitlab.com:prometeus_/prometeus.git
cd prometeus

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Init and start dev node with contract

cd node
./init.sh

or to start already initialized node

geth --dev --datadir chaindata/ --minerthreads 1 console

Now dev node with preloaded smart contract is runing on localhost.

Open second terminal and run DataValidator function to initialize new DataOwner in local dev node.

It will create new blockchain accoount, save encrypted DataOwner for more details see the link

cd ../tests
python transactions.py

PoC endpoints using

The system has deployed with local dev geth node and have no any transactions with main blockchain. Thera hosts to serve PoC endpoints:

• https://api.prometeus.io
• https://storage.prometeus.io

First create DataValidator account in PoC enviroment

Initialize DataValidator endpoint

https://api.prometeus.io/init_data_validator

it returns new account related credentials with some coins on balance

Initialize DataOwner endpoint

https://api.prometeus.io/init_data_owner

• creates blokchain account for DataOwner and link it with DataValidator blokchain account
• map DataValidator->DataOwner is stored in smart contract
• encrypt DataOwner data set and save file to the store

    "data":"DataOwner data to store",
