Who’s sticking around Layer-1?

As the Ethereum Layer-2 (“L2”) space continues to grow, we will see a reexamining of what each layer’s purpose might mean. Ethereum has been largely inaccessible to the masses for some time due to, among other reasons, high transaction fees. As L2s begin to alleviate this pain, many are beginning to ask what will the future hold for L1 Ethereum? What purpose will it serve?

As cheaper L2 scaling solutions come online in the coming months, projects will have to make decisions about accessibility and scale. We propose a new use for L1, as we begin a slow migration to other execution environments in the second layer. …

Fuel Labs and Burner Wallet team up for world takeover

Today we release an experimental version of Burner Wallet powered by Fuel.

Burner Wallet has been a mainstay of Ethereum technology over the past two years, being used in hundreds of settings at Ethereum’s largest events. The success of the Burner Wallet has come from the focusing on providing an easy UX that beginners can easily use.

One important factor in this user experience is ensuring that transactions can process quickly, reliability and with little-to-no transaction fee. …

Fuel Labs Inc. introduces Yul+ a new low-level language for Ethereum.

Today, Fuel Labs introduces Yul+, which adds various QoL features to Yul, a low-level intermediate language for the Ethereum Virtual Machine.

Yul is an incredible little language written by the Solidity Developers as a compilation target for further optimizations. It features a simplistic and functional low-level grammar. It allows the developer to get much closer to raw EVM than Solidity, and with that comes the promise to drastically improved gas usage.

Fuel Labs has implemented its initial open-beta optimistic rollup contract largely with Yul, but we noticed that with the addition of even a tiny number of basic language additions, our code could become more legible and efficient. …

Fuel is a complete optimistic rollup sidechain currently operating on Ethereum’s Ropsten and Görli testnets.

Today we will go through getting started with Fuel!

Why Use Fuel?

  • 💸 Cost: extremely low transaction fees for any ERC-20 tokens or ether (below 3500 gas per tx, to be 2400 in v1.0 VS currently ~21–50,000 gas)
  • Speed: quick zero-conf. transaction times (below 1.4s, avg. 0.8 seconds)
  • 🔀 Meta-transactional: pay fees in any ERC-20 token or ether
  • 🛣️ High throughput: can handle extremely high volumes of token and ether transactions (i.e. in the 10s of thousands per second)
  • Production direction: our architecture is carefully crafted for large-scale fault-tolerant consumer hardware settings for both validation and usage, without any reliance on novel cryptography, trusted setups, or expensive or customized computing…


Scaling arrives all the same…and now it’s here

A little over two months we announced that sustainable scaling would be coming to Ethereum in the form of Fuel, the most advanced, efficient, and secure optimistic rollup. As of a few days ago, the long wait is finally over: our first public testnet is now live, and the code is open-source! Fuel v0 is a series of short-lived testnets that test stability and performance, and will see a series of improvements over the coming months. We’re aiming for launching a long-lived testnet of Fuel v1 by the end of Q1 2020.

Fuel v0 Features

⛽ The Fuel v0 testnets will be a series of short-lived testnets as we iteratively improve performance and stability and add new features (which we’ll discuss in the next section). …


A future with sustainable, trustless scaling for Ethereum

Two months ago, a small group of Ethereum engineers and researchers got together to work on what would later be popularized by Vitalik Buterin as optimistic rollups. Our work was based on the research and efforts of the ConsenSys researcher John Adler, who spec’ed out the technique as a viable scalability solution several months prior. He described a scalability approach on Ethereum that involved no consensus changes to layer-1, and could be implemented right away to help relieve Ethereum’s state bloat issue caused primarily by ERC-20 token (and specifically, Tether stablecoin) transfers. …
