# Avalanche Subnets

## Concepts

1. Avalanche's high-level components: Avalanche -> Subnets -> Chains -> VMs
2. Every subnet / chain / vm has an unique ID.
3. Blackhole: `0x0100000000000000000000000000000000000000`, it is unchangeable.

## Launch Node (avalanchego)

Check the [official doc](https://docs.avax.network/nodes/build/run-avalanche-node-manually) for launching a node (including AWS/GCP).

You can set optional custom configs by the `--chain-config-dir` parameter, and the default directory path is `$HOME/.avalanchego/configs/chains/`.

References
1. [Avalanchego Config and Flags](https://docs.avax.network/nodes/maintain/avalanchego-config-flags#--chain-config-dir-string)
1. [Chain Configs](https://docs.avax.network/nodes/maintain/chain-config-flags)
1. [Subnet Chain Configs](https://docs.avax.network/subnets/customize-a-subnet#chain-configs)

## Create a Subnet

Create subnet by `subnet-cli`.
1. `subnet-cli` uses the key specified in file `$PWD/.subnet-cli.pk` on the P-Chain to pay for the transaction fee.
1. `subnet-cli` uses Fuji by default. To use mainnet, add `--public-uri https://api.avax.network` ([details](https://docs.avax.network/subnets/subnet-cli#network-selection)).
1. [Avalanche transaction fee](https://docs.avax.network/quickstart/transaction-fees) lists the subnet action fees.

Launch validator. When running `avalanchego`, add

* `-—http-host=0.0.0.0`: Make MetaMask can access the RPC URL
* `--http-allowed-hosts="*"`: Allow traffic from the RPC node (since v1.10.3)

```sh
./avalanchego \
--track-subnets=81vK49Udih5qmEzU7opx3Zg9AnB33F2oqUTQKuaoWgCvFUWQe\
--network-id=fuji \
--http-host=0.0.0.0 \
--http-allowed-hosts="*" \
--public-ip=
```

## Add Validator to Subnet

High-level concepts

1. Make a node as validator
1. Visit [wallet.avax.network](https://wallet.avax.network/wallet/earn)
1. Follow the steps in [this official doc](https://docs.avax.network/nodes/validate/add-a-validator#add-as-a-validator).
1. Ensure there is sufficient balance on P-Chain.
1. Add the validator to the subnet
1. Ues subnet admin to run `subnet-cli`. Find the Subnet admin in the Subnets section below.
1. In general, you will run `subnet-cli` on your notebook instead of validator nodes.
1. You can use [`avalanchego-api-scripts/subnet-cli/install-subnet-cli-testnet.sh`](https://github.com/numbersprotocol/avalanchego-api-scripts/blob/main/subnet-cli/subnet-cli-add-subnet-validator-testnet.sh) to install.
1. Run the command

```shell
# testnet
subnet-cli add subnet-validator \
--node-ids="NodeID-7TwAjiRpTbNcqUx6F9EoyXRBLAfeoQXRq" \
--subnet-id="81vK49Udih5qmEzU7opx3Zg9AnB33F2oqUTQKuaoWgCvFUWQe"

# mainnet
subnet-cli add subnet-validator \
--node-ids="NodeID-BXTBUqX8gitUDtVam4fhRWGD1SfeHGoBx" \
--subnet-id="2gHgAgyDHQv7jzFg6MxU2yyKq5NZBpwFLFeP8xX2E3gyK1SzSQ" \
--public-uri "https://api.avax.network"
```

1. `subnet-cli` will find private key from `$PWD/.subnet-cli.pk` by default.
1. The wallet needs to have 0.001 AVAX at least on P-Chain (Fuji).

If you see `Error: validator not found` when adding a validator to subnet and confirmed that you've re-staked successfully, you can check if the node is running as P-Chain validator by checking the node's explorer page: `https://subnets-test.avax.network/validators/NodeID-`. After re-staking, P-Chain needs minutes to update the validator status.

## Renew Validator

If the validator's staking duration is expired, the staking amount and rewards will be sent to the staking wallet on P-Chain automatically. You can follow the same steps above to add it as a validator again.

Before validation staking expires, any wallet can not stake to a validator again. If you try to do so on wallet.avax.network, you will get the error message

> couldn't issue tx: attempted to issue duplicate validation for NodeID-A2Z8m7egVLhKf1Qj14uvXadhExM5zrB7p

Validator version distributions: [mainnet](https://explorer-xp.avax.network/validators), [testnet](https://explorer-xp.avax-test.network/validators)

[Renew Numbers Validators](https://app.asana.com/0/1202305127727547/1202919355642524/f) (internal task)

### BLS Public Key and BLS Signature

If you're asked to provide BLS Public Key and BLS Signature, you can get them by running the following command on the validator node:

```sh
curl -X POST --data '{
"jsonrpc":"2.0",
"id" :1,
"method" :"info.getNodeID"
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/info
```

It should return something like this.

```sh
{
"jsonrpc": "2.0",
"result": {
"nodeID": "NodeID-5mb46qkSBj81k9g9e4VFjGGSbaaSLFRzD",
"nodePOP": {
"publicKey": "0x8f95423f7142d00a48e1014a3de8d28907d420dc33b3052a6dee03a3f2941a393c2351e354704ca66a3fc29870282e15",
"proofOfPossession": "0x86a3ab4c45cfe31cae34c1d06f212434ac71b1be6cfe046c80c162e057614a94a5bc9f1ded1a7029deb0ba4ca7c9b71411e293438691be79c2dbf19d1ca7c3eadb9c756246fc5de5b7b89511c7d7302ae051d9e03d7991138299b5ed6a570a98"
}
},
"id": 1
}
```

The publicKey is your BLS Public Key, and proofOfPossession is your BLS Signature. Avalanche uses your public key as the signing message ([source 1](https://docs.avax.network/nodes/validate/add-a-validator#validation-period), [source 2](https://docs.avax.network/nodes/maintain/node-backup-and-restore#nodeid)).

## RPC

[MetaMask RPC rule](https://docs.avax.network/subnets/deploy-a-smart-contract-on-your-evm#step-1-setting-up-metamask): `http://NodeIPAddress:9650/ext/bc/BlockchainID/rpc`

### Set RPC

Use Nginx as RPC load balancer.

```sh
$ vim /etc/nginx/sites-available/default
```

### Test RPC

Test POST on the RPC node locally:

```sh
$ cat check_version.sh
#!/bin/bash

curl -X POST --data '{
"jsonrpc": "2.0",
"id": 10508,
"method": "eth_chainId"
}' -H "Content-Type: application/json" http://localhost
```

Testing result:

```sh
$ ./check_version.sh
{"jsonrpc":"2.0","id":10508,"result":"0x290c"}
```

## Upgrade Node (avalanchego)

[Upgrade Your AvalancheGo Node](https://docs.avax.network/nodes/maintain/upgrade-your-avalanchego-node)

1. Backup node

```sh
cd
cp ~/.avalanchego/staking/staker.crt .
cp ~/.avalanchego/staking/staker.key .
```

1. Download pre-build `avalanchego` and `subnet-evm`
1. Copy `subnet-evm` binary to `avalanchego/plugins/`
1. Stop the running `avalanchego`
1. Start the new `avalanchego`

Notes

1. When upgrading node, you need to upgrade EVM and plugins as well.

> Plugin is the part of the installation. And it has to be upgraded along with the main executable, yes.

Since `avalanchego v1.9.6`, there are two breaking changes

1. There is no `avalanchego/plugins/evm` (Subnet EVM) because it has been merged into `avalanchego` directly.
1. The default plugins directory is `~/.avalanchego/plugins/`

```
$ tree avalanchego-v1.9.6
avalanchego-v1.9.6
└── avalanchego

$ tree ~/.avalanchego/plugins/
/home//.avalanchego/plugins/
└── kmYb53NrmqcW7gfV2FGHBHWXNA6YhhWf7R7LoQeGj9mdDYuaT
```

## Update subnet-evm

1. Download the latest pre-built binary on [subnet-evm GitHub](https://github.com/ava-labs/subnet-evm).
1. Copy the subnet-evm binary to `~/.avalanchego/plugins/`
1. Restart node (`avalanchego`)

## Updating Utilities

See `chains/update-validator-{mainnet,testnet}.sh`.

## Network Upgrades: Enable/Disable Precompiles

## Customize Subnet and EVM

> Each blockchain has some genesis state when it’s created.
> Each Virtual Machine defines the format and semantics of its genesis data.

Config directory structure

```sh
$ tree ~/.avalanchego/configs/
/home/ubuntu/.avalanchego/configs/
├── chains
│ └── 29YUizsFS9pFPvYjsSKB23M2QAooU1yCE2dfSw6pBhpL46SA18
│ └── config.json
└── subnets
└── 2fQBahhq3F9eip8KobMgjbvBEahW3153kvAy6YPDrGMTceZcGG.json
```

Tips
1. After updating `config.json`, `avalanchego` needs to be restarted.
2. If you add fee recipient, the fee recipient will get 100% gas fee.

## Precompile: Minting Native Coins

```
> contract = await ethers.getContractAt("NativeMinterInterface", "0x0200000000000000000000000000000000000001")

> [admin] = await ethers.getSigners()

> await admin.getBalance()
BigNumber { value: "99999999999845284000000300" }

> r = await contract.mintNativeCoin(admin.address, 100)

> await admin.getBalance()
BigNumber { value: "99999999999793712000000400" }
```

Check the [official doc](https://docs.avax.network/subnets/customize-a-subnet#minting-native-coins) for the details.

## Admin

[avalanchego-api-scripts](https://github.com/numbersprotocol/avalanchego-api-scripts) is the admin toolkit.

### Confirm Updated Node Is Working

Node will show "consensus starting" for both C-Chain and P-Chain:

```
[10-02|06:32:32.114] INFO snowman/transitive.go:401 consensus starting {"lastAcceptedBlock": "2L56FDEYAemMKTJ2uD1MnGpC1pC2WBgeNtwyjh6AhgTffvCWR2"}
[10-02|06:32:32.117] INFO

snowman/transitive.go:401 consensus starting {"lastAcceptedBlock": "22egidV1exdWT8ckaAf8dv9YiWAs2ESmY2NmtJUwNqBGCyNef2"}
[10-02|06:32:41.919] INFO avalanche/transitive.go:346 consensus starting {"lenFrontier": 1}
```

Now, you can check if the Node is running normally.

Using `info.peers` to check all the nodes and versions in a subnet. The nodes might not be validators. The node running the command will not be listed in the result. Remember to add `--public-ip=` when running `avalanchego`. Check public IPs are correct and uptimes are > 98.

# HTTPS RPC Provider

Concept: Nginx with Certbot as reverse proxy redirects RPC requests to the validators.

# Websocket RPC Provider

Concept: Nginx with Certbot as reverse proxy redirects RPC requests to the websocket endpoint of validators.

Websocket log subscription example using Python:

```sh
pip3 install websockets
```

```python
import asyncio
import json

from websockets import connect

async def get_event():
async with connect('wss://testnetrpc.num.network/ws') as ws:
await ws.send('{"jsonrpc":"2.0", "id": 1, "method": "eth_subscribe", "params": ["logs", {"topics": []}]}')
subscription_response = await ws.recv()
print(subscription_response)
while True:
try:
message = await asyncio.wait_for(ws.recv(), timeout=60)
print(json.loads(message))
except asyncio.TimeoutError:
pass
except Exception as e:
print(f'Error: {e}')
break

if __name__ == '__main__':
asyncio.run(get_event())

```

# Self-Hosted Faucet

https://faucet.num.network

1. Create product build.

2. Copy `build/client/*` to `/var/www/html/faucet/`.
3. Update Nginx config.

```
+upstream faucet {
+ server localhost:8000
+}
...
- root /var/www/html;
+ root /var/www/html/faucet;
...
+ location /api/ {
+ proxy_pass http://faucet
+ }
```

4. Run product server: `npm start`
5. Utility commands

```
$ sudo service nginx configtest
$ sudo service nginx reload

# Wrapped NUM

We completed a technical survey and verified some concepts on the testnet.

If you are interested in wrapped ERC20 token, refer to [canonical-wnum](https://github.com/numbersprotocol/canonical-wnum/).

# Bridge

To bridge native NUM to ERC20/BEP20 NUM, you can use [XY Finance](https://app.xy.finance/) ([audit report](https://docs.xy.finance/getting-started/security)).

To know more about NUM token, you can visit the [NUM token website](https://num.numbersprotocol.io/).

# Archieve Node

Archive Node provides full history of the blockchain and does not need to be a validator.

[Running an Archival Node](https://docs.avax.network/dapps/launch-your-ethereum-dapp#running-an-archival-node)
* [state sync bootstrapping has to be off](https://docs.avax.network/nodes/build/set-up-node-with-installer#running-the-script).
* [~2TB storage size for archive node](https://support.avax.network/en/articles/6158842-nodes-faq)

Make a Full Node instance to be an Archive Node instance:
1. Create an instance from full node image
1. Increase disk space to 2TB
1. Delete `~/.avalanchego/staking/*`
1. Update network config
* mainnet: `~/.avalanchego/configs/chains/2PDRxzc6jMbZSTLb3sufkVszgQc2jtDnYZGtDTAAfom1CTwPsE/config.json`
* testnet: `~/.avalanchego/configs/chains/2oo5UvYgFQikM7KBsMXFQE3RQv3xAFFc8JY2GEBNBF1tp4JaeZ/config.json`
