Thread on How to Create an $AVAX Subnet Part 1! 👇👇👇

This thread is very basic and will not cover all the processes involved.

Hopefully this thread is used strictly to gain context regarding the overview of how Subnets are created.

Please do all research possible.

1/

Before we begin, I will provide the outline of what we intend to cover.

- Demystifying Subnets
- Clarifying the term Subnet
- What is an EVM instance?
- What are validator requirements?
- How to deploy a Subnet
- Concluding Thoughts
- Links to Github repositories

Let’s begin:

This is for all audiences even if you don’t have a technical background but are interested in Subnets please read this thread.

I will try my best to break this down as simply as I can.

Here's four helpful preliminary ideas for comprehension:

3/

1. Blockchains are just code.
2. Subnets are just code.
3. Code is written in programming languages.
4. This code is open for anyone to learn.

Here’s a great thread compilation by Connor Daly that outlines what you need to get started as a dev.

4/

Open-source code is made free for anyone to modify, change, alter, or implement.

Open source is how we advance. #Ethereum was made open source, same with #Bitcoin.

This is why we are able to improve upon their code. As anyone is allowed to play with it.

5/

We actually have a major shortage in blockchain devs.

As blockchains aren’t yet mainstream, most developers are learning skills to deploy Web2 applications.

But if you start today or within the next decade, you will have a distinct advantage over Web2 devs.

6/

Now let’s begin.

What is a Subnet?

Simply put, a Subnet is a set of validators.

A Subnet validates a set of blockchains Each blockchain is validated by exactly one subnet.

You can run an EVM or your own custom blockchain on a subnet.

7/

Public Subnets have built in cross subnet communication capabilities.

#Ethereum is an EVM, EVM actually stands for Ethereum Virtual Machine.

If you want to have your own Ethereum chain on a Subnet, you need to run a Subnet EVM.

8/

Think of this as an operating system, like Mac or Windows.

Subnet EVM is refined from Coreth EVM.

You don’t have to code it on your own, as the devs over at Ava-Labs have made this open source.

9/

Now with a Subnet EVM, you define your gas mechanism.

You can have a feeless EVM or implement a gas fee structure.

In this guide we won’t cover the specifics of modifying the EVM.

Let’s just focus on getting a subnet up and running.

10/

Remember we said a Subnet is a set of validators?

What's required to run a validator?

Each validator is a node. A node has low system requirements, they can actually run-on hardware as minimal as a raspberry pi.

The more validators we have = the more decentralized.

11/

To run a validator, you need 2,000 $AVAX staked and locked.

If you want to get started, then Amazon has recently offered a validator service under AWS.

12/

Currently the fastest way to create a subnet is subnet-cli (Command Line Interface).

Suppository Here:
github.com/ava-labs/subne…

This CLI simplifies the process by refining the subnet creation to a wizard tool.

13/

Now what do we do Bubba?

Follow the actual tutorial to see the in-depth processes!

- Generate the control keys
- Create the Subnet
- Verifying Success
- Adding Subnet Validators
- Issuing Validator Transaction
- Whitelisting the Subnet
- Private Subnets

14/

When a subnet is created two things are specified:

1. A Threshold
2. Set of Keys

These are created so we can add a validator using threshold signatures.

For this thread we will call them Subnet’s Control Keys.

15/

Also, for this thread we'll call a control key’s signature a Control Signature.

You can generate the control keys here:

docs.avax.network/build/tutorial…

16/

Create The Subnet:

All we have to do is call platform.createSubnet within the code, The response gives us the transaction’s ID.

Which is also the ID of the newly created Subnet.

You can create a Subnet here:

docs.avax.network/build/tutorial…

17/

Verifying Success:

To make sure we did everything right and nothing failed or resulted in error.

We can call platform.getSubnets to get all Subnets that exist.

The response we receive after the call should confirm that our subnet was created.

18/

You can verify if you successfully created a Subnet here:

docs.avax.network/build/tutorial…

19/

Now let’s add a validator to a Subnet.

Right now, you can only add validators to subnets with API calls, not with Avalanche Wallet.

Assuming you have a Subnet ID, threshold of 2, and username has at least 2 control keys.

20/

Next is to add the subnet via the API method platform.addSubnetValidator to receive a signature.

Use These Parameters:

- nodeId: The ID of the node
- subnetId: The ID of the subnet
- startTime and endTime: The set time a validator starts/stops validating

21/

- weight: the sample weight for consensus.

Weight explained:

This is very cool, I just wanted to bring context Avalanche was built with efficiency in mind.

Being one of the top eco efficient blockchains through working only when needed, not wasting any.

22/

For Example:

If sample weight is set to 1, then your validator will be included in about 1 in every 100 samples during consensus.

Not wasting resources being involved in the other 99 samples. By default, snow-sample-size is 20.

23/

Tangent over. Back to parameters:

- changeAddr: Any change resulting from this transaction will be sent to this address.

- username and password: Self-explanatory, username and password of the user that pays the transaction fee.
