# Demo
|
||
|
||
Stack components:
|
||
* `ipld-eth-db` database for statediffed data
|
||
* Local geth + lighthouse blockchain "fixturenet" running in statediffing mode
|
||
* `ipld-eth-server` which runs an ETH RPC API and a GQL server; serves data from `ipld-eth-db`
|
||
* A go-nitro deployment acting as the Nitro node for `ipld-eth-server`
|
||
* A modified reverse payment proxy server (based on the one from go-nitro) that proxies requests to `ipld-eth-server`'s RPC endpoint; it talks to `ipld-eth-server`'s Nitro node to accept and validate payments required for configured RPC requests
|
||
* A MobyMask v3 watcher that pays the `ipld-eth-server` for ETH RPC requests
|
||
* A MobyMask v3 app that pays the watcher for reads (GQL queries) and writes
|
||
* An example ERC20 Ponder app that pays the `ipld-eth-server` for ETH RPC requests
|
||
|
||
## Setup
|
||
|
||
* On starting the stack, MobyMask watcher creates a payment channel with the `ipld-eth-server`'s Nitro node. Check watcher logs and wait for the same:
|
||
|
||
```bash
|
||
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
|
||
# ...
|
||
# ts-nitro:util:nitro Virtual payment channel created with id 0x29ff1335d73391a50e8fde3e9b34f00c3d81c39ddc7f89187f44dd51df96140e
|
||
# 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:
|
||
|
||
```bash
|
||
export WATCHER_UPSTREAM_PAYMENT_CHANNEL=<PAYMENT_CHANNEL_ID>
|
||
```
|
||
|
||
* Check the payment channel status:
|
||
|
||
```bash
|
||
docker exec payments-nitro-rpc-client-1 npm exec -c "nitro-rpc-client get-payment-channel $WATCHER_UPSTREAM_PAYMENT_CHANNEL -h go-nitro -p 4005"
|
||
|
||
# Expected output:
|
||
# {
|
||
# ID: '0x8c0d17639bd2ba07dbcd248304a8f3c6c7276bfe25c2b87fe41f461e20f33f01',
|

# AssetAddress: '0x0000000000000000000000000000000000000000',
|
||
# Payee: '0xaaa6628ec44a8a742987ef3a114ddfe2d4f7adce',
|

# Payer: '0xbbb676f9cff8d242e9eac39d063848807d3d1d94',
|
||
# PaidSoFar: 0n,
|
||
# RemainingFunds: 1000000000n
|
||
# }
|
||
# }
|
||
```
|
||
|
||
* In another terminal, check the reverse payment proxy server's logs to keep track of incoming payments and RPC requests:
|
||
|
||
```bash
|
||
docker logs -f $(docker ps -aq --filter name="nitro-reverse-payment-proxy")
|
||
```
|
||
|
||
* MetaMask flask wallet setup for running the MobyMask app:
|
||
|
||
* Get the geth node’s port mapped to host:
|
||
|
||
```bash
|
||
docker port payments-fixturenet-eth-geth-1-1 8545
|
||
```
|
||
|
||
* In MetaMask, add a custom network with the following settings:
|
||
|
||
```bash
|
||
# 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:
|
||
|
||
```bash
|
||
# 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:
|
||
|
||
```bash
|
||
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:
|
||
|
||
```bash
|
||
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:
|
||
|
||
```bash
|
||
# Expected output:
|
||
# ...
|
||
# laconic:payments Serving a paid query for 0x86804299822212c070178B5135Ba6DdAcFC357D3
|
||
# vulcanize:resolver isPhisher 0x98ae4f9e9d01cc892adfe6871e1db0287039e0c183d3b5bb31d724228c114744 0x2B6AFbd4F479cE4101Df722cF4E05F941523EaD9 TWT:ash1
|
||
# vulcanize:indexer isPhisher: db miss, fetching from upstream server
|
||
# laconic:payments Making RPC call: eth_chainId

# laconic:payments Making RPC call: eth_getBlockByHash
|
||
# laconic:payments Making RPC call: eth_chainId
|
||
# laconic:payments Making RPC call: eth_getStorageAt
|
||
```
|
||
|
||
* The watcher makes several ETH RPC requests to `ipld-eth-server` to fetch data required for satisfying the GQL request(s); check the payment proxy server logs for charged RPC requests (`eth_getBlockByHash`, `eth_getBlockByNumber`, `eth_getStorageAt`):
|
||
|
||
```bash
|
||

```
|
||
|
||
* 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:
|
||
|
||
```bash
|
||
# Expected output:
|
||
# ...
|
||
# vulcanize:libp2p-utils [6:50:2] Received a message on mobymask P2P network from peer: 12D3KooWRkxV9SX8uTUZYkbRjai4Fsn7yavB61J5TMnksixsabsP

|

```
|
||
|
||
* Check the watcher - ipld-eth-server payment channel status after a few requests:
|
||
|
||
```bash
|
||
docker exec payments-nitro-rpc-client-1 npm exec -c "nitro-rpc-client get-payment-channel $WATCHER_UPSTREAM_PAYMENT_CHANNEL -h go-nitro -p 4005"
|
||
|

|
||
# }
|
||
# }
|
||
```
|
||
|
||
### ERC20 Ponder App
|
||
|
||
* Run the ponder app in it's container:
|
||
|
||
```bash
|
||
docker exec -it payments-ponder-app-1 bash -c "pnpm start"
|
||
|
||
# Expected output:
|
||
# 09:58:54.288 INFO payment Creating ledger channel with nitro node 0xAAA6628Ec44A8a742987EF3A114dDFE2D4F7aDCE

|
||
```
|
||
|
||
* On starting the Ponder app, it creates a payment channel with the `ipld-eth-server`'s Nitro node and then starts the historical sync service
|
||
|
||
* The sync service makes several ETH RPC requests to the `ipld-eth-server` to fetch required data; check the payment proxy server logs for charged RPC requests (`eth_getBlockByNumber`, `eth_getLogs`)
|
||
|
||
```bash
|
||

|
||
# ...
|
||
```
|
||
|
||
* Export the payment channel id to a variable:
|
||
|
||
```bash
|
||
export PONDER_UPSTREAM_PAYMENT_CHANNEL=<PAYMENT_CHANNEL_ID>
|
||
```
|
||
|
||
* Check the ponder - ipld-eth-server payment channel status:
|
||
|
||
```bash
|
||
docker exec payments-nitro-rpc-client-1 npm exec -c "nitro-rpc-client get-payment-channel $PONDER_UPSTREAM_PAYMENT_CHANNEL -h go-nitro -p 4005"
|
||
|
||
# Expected output ('PaidSoFar' is non zero):

|
||
# RemainingFunds: 999785000n
|
||
# }
|
||
# }
|
||
```
|
||
|
||
## 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:
|
||
|
||
```bash
|
||
await clearNodeStorage()
|
||
```
|
||
|
||
* On a fresh restart, clear activity tab data in MetaMask for concerned accounts
