@ -26,15 +26,31 @@ This simple use case showcases many interesting and distinctive aspects of NuCyp
|
|||
- The Doctor never interacts with Alicia or the Heart Monitor:
|
||||
he only needs the encrypted data and some policy metadata.
|
||||
|
||||
### How to run the demo
|
||||
### Decentralized Network Demo
|
||||
|
||||
Ensure that you already have `nucypher` installed.
|
||||
|
||||
Run a fleet of federated Ursulas in a separate terminal:
|
||||
First, configure the demo by making exporting environment variables
|
||||
with your provider and wallet details for ethereum and polygon.
|
||||
|
||||
```sh
|
||||
(nucypher)$ python ../run_demo_ursula_fleet.py
|
||||
```bash
|
||||
export DEMO_L1_PROVIDER_URI=<YOUR ETH PROVIDER URL>
|
||||
export DEMO_L2_PROVIDER_URI=<YOUR POLYGON PROVIDER URL>
|
||||
export DEMO_L2_WALLET_FILEPATH=<YOUR WALLET FILEPATH>
|
||||
export DEMO_ALICE_ADDRESS=<YOUR ALICE ETH ADDRESS>
|
||||
```
|
||||
This will create a local network of federated Ursulas that will be used by the demo for re-encryption of data.
|
||||
|
||||
Alternatively you can use the provided .env.template file by making a copy named .env
|
||||
and adding your provider and wallet details. To set the variables in your current session run:
|
||||
`export $(cat .env | xargs)`
|
||||
|
||||
Optionally, you can change the network the demo is running on by changing the value of `L1_NETWORK` and `L2_NETWORK`.
|
||||
If you change these values be sure to also change `L1_PROVIDER_URI` and `L2_PROVIDER_URI` accordingly.
|
||||
|
||||
Available options for `L1_NETOWRK` are `ibex` or `mainnet`.
|
||||
Available options for `L2_NETWORK` are `mumbai` or `mainnet`
|
||||
|
||||
Ensure Alice's account has a bit of MATIC on polygon to pay for the policy.
|
||||
|
||||
Subsequently, running the demo only involves running the `alicia.py` and `doctor.py` scripts.
|
||||
You should run `alicia.py` first:
