Demo

Stack components:

• ipld-eth-db database for statediffed data
• Local geth + lighthouse blockchain "fixturenet" running in statediffing mode
• ipld-eth-server-1 which runs an ETH RPC API and a GQL server; they both serve data from ipld-eth-db
  • It runs an in-process go-nitro node for payments required for configured RPC requests
• A MobyMask v3 watcher that pays the ipld-eth-server-1 for ETH RPC requests
• A MobyMask v3 app that pays the watcher for reads (GQL queries) and writes

Setup

• On starting the stack, MobyMask watcher creates a payment channel with the ipld-eth-server-1's (in-process) Nitro node. Check watcher logs and wait for the same:

  docker logs -f $(docker ps -aq --filter name="mobymask-watcher-server")
  
  # Expected output:
  # vulcanize:server Peer ID: 12D3KooWKLqLWU82VU7jmsmQMruRvZWhoBoVsf1UHchM5Nuq9ymY
  # vulcanize:server Using chain URL http://fixturenet-eth-geth-1:8546 for Nitro node
  # ...
  # ts-nitro:util:nitro Ledger channel created with id 0x65703ccdfacab09ac35367bdbe6c5a337e7a6651aad526807607b1c59b28bc1e

  # vulcanize:server Starting server... +0ms
  

• Keep the above command running to keep track of incoming payments and GQL requests from the MobyMask app

• In another terminal, export the payment channel id to a variable:

  export WATCHER_UPSTREAM_PAYMENT_CHANNEL=<PAYMENT_CHANNEL_ID>
  

• Check the payment channel status:

  docker exec payments-nitro-rpc-client-1 npm exec -c "nitro-rpc-client get-payment-channel $WATCHER_UPSTREAM_PAYMENT_CHANNEL -s false -h ipld-eth-server-1 -p 4005"
  
  # Expected output:
  # {
  #   ID: '0x8c0d17639bd2ba07dbcd248304a8f3c6c7276bfe25c2b87fe41f461e20f33f01',

  #     Payee: '0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce',
  #     Payer: '0xbbb676f9cff8d242e9eac39d063848807d3d1d94',
  #     PaidSoFar: 0n,
  #     RemainingFunds: 1000000000n
  #   }
  # }
  

• In another terminal, check ipld-eth-server-1's logs to keep track of incoming payments and RPC requests from the MobyMask watcher:

  docker logs -f $(docker ps -aq --filter name="ipld-eth-server-1")
  

• MetaMask flask wallet setup for running the MobyMask app:

  • Get the geth node’s port mapped to host:

    docker port payments-fixturenet-eth-geth-1-1 8545
    

  • In MetaMask, add a custom network with the following settings:

    # Network name
    Local fixturenet
    
    # New RPC URL
    http://127.0.0.1:<GETH_PORT>
    
    # Chain ID
    1212
    
    # Currency symbol
    ETH
    

  • Import a faucet account with the following private key:

    # Faucet PK
    # 0x570b909da9669b2f35a0b1ac70b8358516d55ae1b5b3710e95e9a94395090597
    

  • Create an additional account for usage in the app; fund it from the faucet account

• Get the generated root invite link for MobyMask from contract deployment container logs:

  docker logs -f $(docker ps -aq --filter name="mobymask-1")
  
  # Expected output:
  # ...
  #   "key": "0x60e706fda4639fe0a8eb102cb0ce81231cf6e819f41cb4eadf72d865ea4c11ad"
  # }
  # http://127.0.0.1:3004/#/members?invitation=<INVITATION>
  

Run

MobyMask App

• Open app in a browser (where MetaMask was setup) using the invite link

• Run the following in browser console to enable logs:

  localStorage.debug = 'ts-nitro:*'
  # Refresh the tab for taking effect
  

• In the app’s debug panel, check that the peer gets connected to relay node and watcher peer

• Open the NITRO tab in debug panel

  • Click on Connect Wallet to connect to MetaMask (make sure that the newly funded account is active)
  • Click on Connect Snap to install/connect snap

• Perform DIRECT FUND with the preset amount and wait for the MetaMask confirmation prompt to appear; confirm the transaction and wait for a ledger channel to be created with the watcher

• Perform VIRTUAL FUND with amount set to 10000 and wait for a payment channel to be created with the watcher

• Perform phisher status check queries now that a payment channel is created:

  • Check the watcher logs for received payments along with the GQL queries:

  • The watcher makes several ETH RPC requests to ipld-eth-server-1 to fetch data required for satisfying the GQL request(s); check ipld-eth-server-1 logs for charged RPC requests (eth_getBlockByHash, eth_getBlockByNumber, eth_getStorageAt):

• Change the amount besides PAY button in debug panel to >=100 for phisher reports next

• Perform a phisher report and check the watcher logs for received payments:

• Check the watcher - ipld-eth-server-1 payment channel status after a few requests:

  docker exec payments-nitro-rpc-client-1 npm exec -c "nitro-rpc-client get-payment-channel $WATCHER_UPSTREAM_PAYMENT_CHANNEL -s false -h ipld-eth-server-1 -p 4005"

  #   }
  # }
  

Clean Up

• In the MobyMask app, perform VIRTUAL DEFUND and DIRECT DEFUND (in order) for closing the payment channel created with watcher

• Run the following in the browser console to delete the Nitro node's data:

  await clearNodeStorage()
  

• Run the following in the browser console to clear data in local storage:

  localStorage.clear()
  

• On a fresh restart, clear activity tab data in MetaMask for concerned accounts
