A Brief Introduction to Fuel

Fuel is a modular execution level (MEL), comparable to Layer 2 protocols such as Polygon (Matic). However, it also possesses certain unique characteristics which we’ll delve into a bit later.

The Fuel Labs team offers smoother performance without sacrificing the security and decentralization advantages inherent to Ethereum. Fuel’s primary mission is to ensure maximum possible security and flexibility in terms of throughput capacity.

But what does this MEL actually mean? The team defines MEL as a verifiable computational system designed for a modular blockchain stack.

But why this particular solution? After all, Ethereum scaling tools like ZK-Rollups and Optimistic-Rollups are currently being widely promoted. The team provided a simple answer to this question: while these solutions do offer some cost savings for users, the increase in throughput capacity they provide is rather modest.

So how does MEL differ from Layer 2? Actually, it all depends on the context. In the current stage of blockchain technology development, all Layer 2 protocols can be seen as modular execution levels (MELs), but not all MELs can be classified as Layer 2.

Key technological aspects of Fuel include:

• the ability to execute parallel transactions instead of sequential ones
• a proprietary virtual machine
• a developer experience built around its own programming language, Sway

We’ll end our introduction to the project here. Thank you for your attention!
