Environment
- avalanchego: v1.11.11
- subnet-evm: v0.6.9
- Avalanche's high-level components: Avalanche -> Subnets -> Chains -> VMs
- Every subnet / chain / vm has an unique ID.
- Blackhole:
0x0100000000000000000000000000000000000000, it is unchangeable.
Check the official doc 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/.

Create subnet by subnet-cli.
subnet-cliuses the key specified in file$PWD/.subnet-cli.pkon the P-Chain to pay for the transaction fee.subnet-cliuses Fuji by default. To use mainnet, add--public-uri https://api.avax.network(details).- Avalanche transaction fee lists the subnet action fees.

- Make a node as validator
- Visit wallet.avax.network
- Follow the steps in this official doc.
- Ensure there is sufficient balance on P-Chain.
- Add the validator to the subnet
-
Ues subnet admin to run
subnet-cli. Find the Subnet admin in the Subnets section below.- In general, you will run
subnet-clion your notebook instead of validator nodes. - You can use
avalanchego-api-scripts/subnet-cli/install-subnet-cli-testnet.shto install.
- In general, you will run
-
Run the command
# 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"
-
subnet-cliwill find private key from$PWD/.subnet-cli.pkby default. -
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-<node-id>. After re-staking, P-Chain needs minutes to update the validator status.
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

Renew Numbers Validators (internal task)
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:
curl -X POST --data '{
"jsonrpc":"2.0",
"id" :1,
"method" :"info.getNodeID"
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/infoIt should return something like this.

Notes
-
When upgrading node, you need to upgrade EVM and plugins as well.
jpop32 — 05/12/2021 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
- There is no
avalanchego/plugins/evm(Subnet EVM) because it has been merged intoavalanchegodirectly. - The default plugins directory is
~/.avalanchego/plugins/
$ tree avalanchego-v1.9.6

$ tree ~/.avalanchego/plugins/
/home/<account>/.avalanchego/plugins/
└── kmYb53NrmqcW7gfV2FGHBHWXNA6YhhWf7R7LoQeGj9mdDYuaT
- Download the latest pre-built binary on subnet-evm GitHub.
- Copy the subnet-evm binary to
~/.avalanchego/plugins/<vmID> - Restart node (
avalanchego)
See chains/update-validator-{mainnet,testnet}.sh.

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=<public-ip> when running avalanchego. Check public IPs are correct and uptimes are > 98.

We completed a technical survey and verified some concepts on the testnet.
If you are interested in wrapped ERC20 token, refer to canonical-wnum.
To bridge native NUM to ERC20/BEP20 NUM, you can use XY Finance (audit report).
To know more about NUM token, you can visit the NUM token website.
Archive Node provides full history of the blockchain and does not need to be a validator.
Make a Full Node instance to be an Archive Node instance:
-
Create an instance from full node image
-
Increase disk space to 2TB
-
Delete
~/.avalanchego/staking/* -
Update network config
