Install

Pedash runs on Linux. Install:

./scripts/install.sh

Setup

Pedash must be pointed at a Hyperledger Indy pool and cloud agent. Get and run a local copy of both:

./scripts/cloudagent.sh

Hyperledger Indy testnet, mainnet and even permissioned independent deployments can easily be configured by changin the genesis transaction file. Simply place the genesis transaction in pedash/genesis.txn. See the Hyperledger Indy docs for which transaction to use for which network (including creating your own). By default, Pedash is configured for a local deployment - no need to change the file.

Usage

The demo sets up a secure channel between a credential issuer (database owner) and a prover (accessor). After setup, there is an E2E pairwise encrypted channel between the two. The issuer sends a credential for accessing the permissioned database to the accessor.

Terminal 1:

cd pedash
python3 issuer.py

Terminal 2:

cd pedash
python3 prover.py

Note for WSL users: install docker in the Windows environment, then connect to it in WSL.
