How to build in crypto.
I'm Connor and I write threads explaining all the concepts you need to master blockchain development.
My goal is to demystify crypto's key ideas and help enthusiasts break into the industry.
Here's a running list of my threads. Enjoy and please share!

Avalanche revolutionizes every layer of the blockchain.
But there's one innovation that stands above the rest.
When I discovered it, I immediately decided to quit my job and go all in.

Should we ban bots on Pangolin?
After the XAVA token sale, community members have had enough of bots pushing out human traders. Many have suggested we add a captcha to our website and only allow real people to take part.
Here's why that won't work.

One year ago today, the Avalanche Ethereum Bridge launched and I deployed the

Avalanche had no users and no dapps.
Just a dream.
Now, we have a thriving ecosystem and an AMAZING Pangolin V2. I can't wait for everyone to try it.

You can now create and launch your own customized Ethereum Virtual Machine (EVM) Subnet from a json config.

Want to build in crypto but don't know where to get started?
Over the next few weeks, I'm tweeting a crash course on how to break into smart contract development. It's the most in-demand skill in crypto. But almost no one knows how to do it.
First, what are smart contracts?

By the end of next year, smart contract developers will no longer be the hottest commodity in crypto.
Instead, it will be subnet engineers who can build and manage the platform for application specific L1s and L2s.
So start learning Avalanche-CLI now anon.

There are currently two ways to go all-in on Subnets.
- Building custom blockchains yourself
- Building tooling to make it easier for others to do so.
We're still in the early days but, there's already enough functionality to build some cool shit.

If you've paid attention to Avalanche-CLI's development, you may have noticed that we've reached an inflection point.
Our MVP for permissionless subnets is basically complete.

Eventually, someone will create a VM that's superior to the EVM, and the world will adopt it.
That VM can launch on Avalanche without the protocol needing to reinvent itself.
This future proofs the network.

• The C-Chain is an EVM chain for smart contracts
• The X-Chain is a UTXO-based chain for payments
• The P-Chain is a custom chain for platform governance and validator setup

To understand the power of subnets, we need to talk about blockchain scalability.
Without sacrificing decentralization, there are two ways to expand blockchain capacity: vertically or horizontally.
In short, faster chains or more chains.

Not to overshadow the bigger news today, but I need to give Avalanche-CLI one last shout out in 2022.

As builders create new subnets, this list of chains will grow.

I am neck deep in Avalanche Subnet docs this week.
Huge improvements are going to start rolling out very soon!

109
There's a hidden downside to building on non-EVM chains.
Hackers have attacked the EVM for fun and profit for over six years. Because of those hacks, we now understand several major classes of Solidity vulnerabilities.
Newer chains don't have that advantage.
5
8
103
The EVM is the present, but it won't be the future.
Custom VM development will take over the world, but we're still so early.
Here's a glimpse into the future🔮
19
30
107
But that's not the only one!
Others are the Bitcoin Script VM, Cardano's UTXO model, Solana's transaction engine, etc.
An Avalanche subnet can run any of these.

7
97
1. Vertical scaling.
Process transactions faster.
The current bottleneck here is storing smart contract call data. Each new block updates the client's internal data structures. These updates require several non-contiguous writes to disk.

Shoutout to all the crypto investors who read my subnet thread over the weekend.

We're really close to a huge Avalanche-CLI release.

The EVM's biggest flaw might be transaction and signature decoding.
With most dapps, I have no idea what I'm signing on my ledger.
If someone hacked my browser and feeds me a bad tx to sign, they can probably also feed me a bad hash to confirm against on screen.
Ugly UX.

Small CLI release today. Mostly just a few bug fixes while we work on bigger changes. I recommend upgrading for some improved stability.

88
But of course, there's a catch.
For chains to operate in parallel, they need to be independent.
That means that individual chains need to be self-contained ecosystems. If you want interoperability, you need to add a cross-chain communication layer.

Warms my heart seeing Subnet Show finally taking off.

2. Horizontal scaling.
Increase capacity by executing multiple blockchains in parallel.
This is where you can have almost unlimited throughput gains.

Is every Avalanche dapp an Ethereum clone?
The ecosystem must be totally derivative. No original work here!
But if you look closer, you'll see something surprising.👇

87
Currently, most Avalanche traffic runs on the C-Chain. That's where DeFi and NFTs currently thrive.
But if you've ever staked or delegated your AVAX, you've used the P-Chain.

85
Across ecosystems, people are making incremental improvements.
Most come by creating more efficient data structures or enforcing beefier hardware requirements.
These gains are gradual and likely won't lead to 1000x returns.

Well, here's a few benefits to building a subnet instead.
1. Abstracted low-level complexity
2. Instant access to liquidity
3. Choice of gas token

Forks can even bootstrap with old chain state.
For example, you could create a Bitcoin subnet and airdrop AVAX-Bitcoin to all existing BTC holders.

Subnets require two things to build:
1. A virtual machine: How to process transacations
2. A validator set: Who can process transactions
