+# MobyMask v3 Demo
+
+Instructions to setup and deploy an end-to-end MobyMask v3 stack (fixturenet-optimism + watchers + web-app) locally using [laconic-stack-orchestrator](/README.md#install)
+
+## Setup
+
+* Clone required repositories:
+
+  ```bash
+  laconic-so --stack mobymask-v3-demo setup-repositories --pull
+  ```
+
+* Build the container images:
+
+  ```bash
+  laconic-so --stack mobymask-v3-demo build-containers
+  ```
+
+* Install MetaMask Flask extension in a chromium browser from chrome web store and follow the setup instructions
+
+## Deploy
+
+* Create a spec file for the deployment:
+
+  ```bash
+  laconic-so --stack mobymask-v3-demo deploy init --output mobymask-v3-demo-spec.yml
+  ```
+
+* Create a deployment from the generated spec file:
+
+  ```bash
+  laconic-so --stack mobymask-v3-demo deploy create --spec-file mobymask-v3-demo-spec.yml --deployment-dir mobymask-v3-demo-deployment
+  ```
+
+* Copy over the demo config to place it at an appropriate path:
+
+  ```bash
+  cp mobymask-v3-demo-deployment/config/watcher-mobymask-v3-demo/local/config.env mobymask-v3-demo-deployment/
+  ```
+
+### Start the stack
+
+* Start the deployment:
+
+  ```bash
+  laconic-so deployment --dir mobymask-v3-demo-deployment start
+
+  # Useful ports exposed on host
+  # 3001: MobyMask v3 watcher 1 GQL endpoint
+  # 9090: MobyMask v3 watcher 1 relay node endpoint
+  # 9091: MobyMask v3 watcher 2 relay node endpoint
+  # 9092: MobyMask v3 watcher 3 relay node endpoint
+  # 8080: MobyMask snap
+  # 3004: MobyMask v3 app
+  ```
+
+  Note: This may take several minutes as it configures and runs the L1, L2 chains and the watchers; you can follow the progress from containers' logs
+
+* To list and monitor the running containers:
+
+  ```bash
+  laconic-so deployment --dir mobymask-v3-demo-deployment ps
+
+  # With status
+  docker ps
+
+  # Check logs for a container
+  docker logs -f <CONTAINER_ID>
+  ```
+
+## Demo
+
+Follow [demo](./demo.md) to try out the MobyMask app
+
+## Clean up
+
+To stop all services running in the background, while preserving data:
+
+  ```bash
+  laconic-so deployment --dir mobymask-v3-demo-deployment stop
+  ```
+
+To stop all services and also delete data:
+
+  ```bash
+  laconic-so deployment --dir mobymask-v3-demo-deployment stop --delete-volumes
+
+  # Also remove the deployment directory
+  rm -rf mobymask-v3-demo-deployment
+  ```
+
+## Known Issues
+
+* Resource requirements (memory + time) for building the `cerc/foundry` image are on the higher side
+  * `cerc/optimism-contracts` image is currently based on `cerc/foundry` (Optimism requires foundry installation)

+# Demo
+
+## Setup
+
+* Follow logs and check that all 3 watchers are running in consensus:
+
+  ```bash
+  # Follow the logs in three different terminals and keep them running
+  docker logs -f $(docker ps --filter "name=mobymask-watcher-1" -q)
+  docker logs -f $(docker ps --filter "name=mobymask-watcher-2" -q)
+  docker logs -f $(docker ps --filter "name=mobymask-watcher-3" -q)
+
+  # Expected output when all three are running in consensus:
+  # ...
+  # 2024-02-21T10:42:23.932Z laconic:consensus State changed to 3 (FOLLOWER) with term 286
+  # 2024-02-21T10:42:23.932Z laconic:consensus State changed to 2 (CANDIDATE) with term 287
+  # 2024-02-21T10:42:24.406Z laconic:consensus State changed to 1 (LEADER) with term 287
+  # ...
+
+  # At any moment, only one of watchers is the 'LEADER'
+  ```
+
+* In MetaMask, go to settings add a custom network with the following settings:
+
+  ```bash
+  # Network name
+  Local Optimism
+
+  # New RPC URL
+  http://127.0.0.1:8545
+
+  # Chain ID
+  42069
+
+  # Currency symbol
+  ETH
+  ```
+
+  Switch to the newly added network
+
+* Import a pre-funded account (using it's private key) for Nitro client in the MobyMask app:
+
+  ```bash
+  # PK: 689af8efa8c651a91ad287602527f3af2fe9f6501a7ac4b061667b5a93e037fd
+  # Address: 0xbDA5747bFD65F08deb54cb465eB87D40e51B197E
+  ```
+
+## Run
+
+### Open MobyMask app
+
+* Copy the generated invite link from MobyMask deployment container logs:
+
+  ```bash
+  docker logs -f $(docker ps -a --filter "name=mobymask-1" -q)
+
+  # A SIGNED DELEGATION/INVITE LINK:
+  # ...
+  # http://127.0.0.1:3004/#/members?invitation=<INVITATION>
+  ```
+
+* Open the invite link in browser where MetaMask was setup
+
+* In the app’s debug panel (bottom-right), check from `PEERS` and `GRAPH` tabs that the peer gets connected to relay nodes and watcher peers
+
+* Perform phisher status checks from the app
+  * First 10 queries are served for free; repeat until the free quota is exhausted
+  * Same can be seen in the watcher-1's logs (the app makes all the GQL queries to watcher-1):
+
+    ```bash
+    # ...
+    # 2024-02-21T11:01:20.084Z laconic:payments Query rate not configured for "latestBlock", serving free query

+    ```
+
+### Setup app's Nitro node
+
+* Open the `NITRO` tab in debug panel
+
+* Click on `Connect Wallet` button to connect to MetaMask (use the imported account with funds)
+
+* Click on `Connect Snap` to install / connect snap; the watcher Nitro clients should show up in the `NITRO` tab
+
+* Click on `DIRECT FUND` button against watcher-1's Nitro account (`0xAAA6628Ec44A8a742987EF3A114dDFE2D4F7aDCE`) to create a ledger channel with the pre-set amount
+  * Confirm the tx in MetaMask popup; wait some time for the tx to be confirmed and ledger channel to be created
+  * The progress can be followed from watcher-1's logs
+  * The created ledger channel should now be visible in the `NITRO` tab; click on `REFRESH` button otherwise
+
+* Change amount to `10000` and click on `VIRTUAL FUND` button to create a virtual payment channel
+  * This results in a payment channel between the app and watcher-1
+  * The payment channel's details should now be visible along with a `PAY` and `VIRTUAL DEFUND` buttons
+
+* Close the debug panel
+
+### Paid queries and mutations
+
+* Perform phisher status checks now that a payment channel has been created
+  * Amount set in the debug panel's `NITRO` tab is sent along with each request to the watcher
+  * Check the watcher-1 logs for the received payments:
+
+    ```bash
+    # ...

+
+* Rate for mutations is set to `100` in the watcher; go back to the `NITRO` tab in the debug panel and change amount value besides `PAY` button to >=100
+
+* Perform a phisher report
+  * Enter a new record(s) and click on `Submit batch to p2p network` button
+  * Among all three watchers running in consensus, whoever is the `LEADER` at time of reporting sends a tx to the chain
+  * Check all the watchers' logs:
+
