easiest way to understand why crypto has pmf is to try withdrawing 5 figs from a bank account

Today we announced the FUEL token.
Used in our effort to decentralize sequencing and improve UX by eliminating gas fees outright.
For too long, blockchains have operated like a pay to play model, making it wholly uncompetitive with a web2 experience. This changes today.
Thanks to the execution improvements of the Fuel architecture, fees are going to zero, and with that we might as well go all the way and make it free for users outright. More details to come on how we do this throughout the week.
With that, none of this would be possible without the Fuel community. They have been eating glass for years, and we want to ensure we do a launch worthy of their support.
In addition, we want to take a last step to grow our community before launch, so we have partnered with a few awesome teams to help us do that.
It’s been a wild ride building Fuel, and today we start a new chapter.
LFG. ⛽️

Fuel Genesis is coming.
Introducing FUEL—the native token of the Fuel network.

Imagine rearchitecting and rebuilding:
- The EVM
- Solidity
- Foundry
- Indexers
- geth (without consensus)
- A complete block explorer
- A complete wallet
- WalletConnect
All with modern design and making it all work nicely together.
That’s what the Fuel team did for Ignition. And I couldn’t be more proud of them.
Ignition is just the beginning ⛽️

I see people all the time tell me that crypto “isn’t innovating” or “what are the use cases”.
They have completely missed the plot.
Just stablecoins and multisigs are an insanely incredible use case for crypto.
You can start groups, companies and organizations in seconds with built in majority governance and send and recieved money around the world without borders, with no need for a government to approve or enforce the rules.
You can pay people in 13 seconds or less. You can pay hundreds of people in 13 seconds or less.
There is no barrier to creating these other than some very menial fees.
On just this alone, crypto is worth trillions.
Stop trying to find magical use cases for things. Let’s take a step back and look at what we have already. And we haven’t even gotten started yet with the possibilities of multisigs and stablecoins.
I’m not even including uniswap, decentralized stables or fancy Defi here. Just USDC and a multisig, it’s incredible.

The race to scale and develop blockchains is on, with VMs, modular frameworks and rollups leading the charge.
But their constraints are the hidden barriers to blockchain scalability.
Let’s dive deeper in Part II of our Ethereum series 🧵

Fuel 🔢 The 🔢 Future
Today, we welcome you to join the Fuel Points Program, an opportunity to qualify for future incentives as we progress toward Fuel Mainnet launch.
This is your chance to join us in shaping the future of Ethereum rollups.

Few tips for @fuel_network Attackathon on @immunefi.
Tip 1: Start looking for bugs on FuelVM. There's way more to discover there than meets the eye.
Tip 2: Looking for bugs in Sway? Start with the compiler. Don't know Rust? See how the same code in sway acts on Fuel vs equivalent on EVM. Any differences? Worth investigating.
Tip 3: FuelVM, Sway Compiler, Fuel Network Bridge are important for a Fuel so any bug found there will be up to most importance.
Tip 4: Not sure where to start? Take a look at FuelVM. Not sure how to understand something? Talk to people on Immunefi Discord, to other SRs and Fuel Network team in general.
Tip 5: Always write a PoC.

So, I've been quietly working on a new project over the last year... and it's time to share a bit about it 😉
It's time to bring Ethereum back to it's roots, time to bring back the magic that made it so special.
Let me tell you a bit about why I'm so excited about @fuel_network
Rodrigo Araújo retweeted
Solidity to @SwayLang Transpiler achieved externally 🫡
We added an S2S transpiler to the Fuel Toolchain to make it easy for Solidity developers to learn Sway, transpile Solidity contracts, and onboard to Fuel:

It's called @fuel_network V1

A new approach to State Growth.
You can now find @IAmNickDodson's post reposted on Fuel's Mirror: fuel.mirror.xyz/OrgKx3EOE07Y…

I’ve given several talks about state growth recently, and seeing more discussions about the topic, I thought I’d do a quick overview of the problem and the approach we’re taking with Fuel.

2024 will be our biggest year yet.
In Q4 2023, we released WebAuthn, Fuel Indexer, New Sway Standards, and more.

Today I will discuss why the FuelVM is the EVM but greatly improved and what this means for the future of blockchain.

The Fuel team did some hacking around DevConnect.
We built a working prototype of WebAuthn P-256 enabled native transaction signing (using account abstraction) live on Testnet.
No seed phrases, no install, biometric enabled!
Try it now: authn-sign.vercel.app
A quick 🧵
Rodrigo Araújo retweeted
Also bringing a couple of major additions to the @fuel_network TS SDK ⚡️ that will be ready just in time for Istanbul! 🇹🇷
The team has been working so hard, and the DX boost is absolutely going to be worth it. So excited to get people to try it out next week 🫡

Fuel's native bridge is now open 🌉
Anyone can now bridge between Ethereum's Sepolia Network and the Beta-4 testnet.
Enter Fuel: alpha.fuel.network/bridge

The trouble with comments in code.
- No comments is bad. Most people agree. ~40% of code falls here.
- Too many comments is bad. Fewer people agree. My eyes and scrolling finger hurt in this ~40% of code.
Coding is a team sport.
Use comments. Not too much. Mostly the unobvious.
