Fuel Network (FUEL)

What is Fuel Network (FUEL)?

Fuel Network is a modular execution layer designed to tackle the core scalability challenges hindering Ethereum’s widespread adoption. It operates as an optimistic rollup, meaning it executes transactions off-chain and periodically posts the results to the Ethereum mainnet. What sets Fuel apart is its unique architecture, which emphasizes parallel transaction execution and a focus on minimizing on-chain state. This design translates to potentially higher throughput and lower transaction fees compared to traditional rollups.

The network aims to offer a more efficient and developer-friendly environment for decentralized applications (dApps). It achieves this through the Fuel Virtual Machine (FuelVM), an enhanced version of the Ethereum Virtual Machine (EVM). FuelVM supports parallel transaction processing, allowing multiple transactions to be executed concurrently, significantly increasing processing capacity. This represents a fundamental shift from the sequential transaction execution model of the EVM, which can be a bottleneck for complex applications. Moreover, FuelVM supports multiple native assets, simplifying the creation and management of custom tokens within the Fuel ecosystem.

FUEL, the native token of the Fuel Network, plays a crucial role in securing the network, incentivizing participation, and facilitating various ecosystem activities. Deployed as an ERC-20 token on Ethereum, FUEL is designed to migrate and function natively within the Fuel Network’s Layer 2 environment. The Fuel Network’s architecture aims for a blend of speed, efficiency, and decentralisation, positioning it as a promising solution for scaling Ethereum and empowering the next generation of dApps.

How Does Fuel Network (FUEL) work?

Fuel Network operates as a modular execution layer that leverages optimistic rollup technology to enhance Ethereum’s scalability. Its core innovation lies in its ability to process transactions in parallel, a significant departure from the sequential transaction processing of the Ethereum mainnet. This parallel execution is made possible by the FuelVM, a virtual machine designed to efficiently handle concurrent transactions and multiple native assets.

At a high level, Fuel works by aggregating transactions off-chain into batches. These batches are then submitted to the Ethereum mainnet as a single transaction, reducing the burden on the mainnet and lowering gas fees for users. Since Fuel is an optimistic rollup, it assumes that the transactions within these batches are valid unless proven otherwise. Validators, or sequencer proposers, play a crucial role in ensuring the integrity of the network. These validators stake FUEL tokens to propose and validate blocks. If a submitted batch is deemed fraudulent, a challenge period ensues, allowing participants to submit a “fraud proof” to the Ethereum mainnet. If the fraud proof is successful, the invalid batch is rejected, and the dishonest validator is penalized.

This system of optimistic validation, combined with parallel transaction execution, enables Fuel to achieve significantly higher transaction throughput compared to Ethereum’s mainnet. This allows for complex dApps with a large number of transactions to operate more efficiently and cost-effectively. The decentralised sequencer architecture, based on a Proof-of-Stake (PoS) model using Tendermint consensus, further contributes to the network’s security and reliability. The Tendermint consensus mechanism facilitates fast and secure block production, ensuring that transactions are processed quickly and accurately. By integrating these advanced technologies, Fuel Network provides a robust and scalable solution for Ethereum’s growing needs.

Fuel Network (FUEL) Key Features and Technology

Fuel Network boasts several key features and technological advancements that set it apart from other Layer 2 scaling solutions. One of its primary strengths is **parallel transaction execution**, powered by the FuelVM. Unlike the Ethereum Virtual Machine (EVM), which executes transactions sequentially, FuelVM enables multiple transactions to be processed simultaneously. This drastically increases transaction throughput and reduces latency, leading to a more responsive and efficient user experience.

Another notable feature is its focus on **state-minimised execution**. By reducing the amount of state data that needs to be stored on-chain, Fuel minimizes the cost and complexity of operating the network. This allows for faster transaction processing and lower gas fees. FuelVM also supports **multiple native assets**, meaning developers can create and manage custom tokens directly within the Fuel ecosystem without relying on standard ERC-20 token contracts. This simplifies the development process and reduces gas costs associated with token creation and management.

The Fuel Network utilises a **decentralised sequencer** built on Proof-of-Stake (PoS) using the Tendermint consensus mechanism. This ensures that the network is secure and reliable, as validators stake FUEL tokens to propose and validate blocks. The Tendermint consensus mechanism facilitates fast block production and finality, which helps to reduce confirmation times and improve the overall user experience. Furthermore, the design of the network provides a more secure and transparent transaction environment.

Finally, Fuel introduces **Application-Specific Sequencing (ASS)**, a mechanism that allows dApps to influence the order and inclusion of transactions. This feature enables advanced functionalities like gasless transactions and personalized user experiences, making it easier for developers to build innovative and user-friendly applications on the Fuel Network. These key features and technologies, working in concert, position Fuel Network as a powerful and versatile scaling solution for Ethereum.

What is Fuel Network (FUEL) used for?

The FUEL token has several critical roles within the Fuel Network ecosystem, making it an integral part of the network’s functionality and growth. Primarily, FUEL is used for **securing the network**. Validators are required to stake FUEL tokens in order to participate in block production and validation.

By staking FUEL, validators earn rewards in the form of transaction fees and newly minted tokens, further encouraging their participation and commitment to the network’s security.

Secondly, FUEL is used to **pay for chain resources**, such as data availability, ordering, and block inclusion on the Fuel sequencer. This ensures that network resources are allocated fairly and efficiently, preventing spam and abuse. By requiring users to pay for these resources in FUEL, the network creates a sustainable economic model that supports its long-term operation and growth.

Another key use case for FUEL is to enable **Application-Specific Sequencing (ASS)**. This innovative mechanism allows decentralised applications (dApps) to influence the order and inclusion of transactions, enabling features like gasless transactions and customized user experiences. Stakers can bond their FUEL to specific applications, earning rewards and enabling gasless transactions for users. This creates a market for Layer 2 chain resources, improving user experience by eliminating transaction fees.

Beyond these core functions, FUEL also plays a significant role in **ecosystem growth**. Over 51% of the total FUEL supply is allocated to community incentives, ecosystem development, and research and development (R&D). These funds are used to attract developers, support innovative projects, and promote the adoption of the Fuel Network. Fuel’s Points Program and partnerships with platforms like Legion, Impossible Finance, and Bitget further incentivise community participation and contribute to the overall growth and vibrancy of the Fuel ecosystem. In summary, FUEL is a multi-faceted token that plays a crucial role in securing the network, allocating resources, enabling advanced functionalities, and driving ecosystem growth.
