Weekly #1 (May 05-11, 2025)
Weekly Highlights
Breakthrough in Transaction Speed: Fuel has become the first blockchain rollup on Ethereum to achieve transaction confirmations in under 100 ms (51 ms regionally, 6 ms with co-located nodes), making it the world’s first real-time rollup on Ethereum. Fuel’s technology, featuring the FuelVM and a parallel UTXO-based transaction model, delivers high performance without compromising security or decentralization. This unlocks opportunities for real-time applications such as trading platforms, gaming, DeFi, and more. Demos are available: Testnet (free) at testnet.swayfarm.xyz, Mainnet (requires ETH) at swayfarm.xyz.
Capability Demonstration: A Twitter post showcased a video of a game featuring a rabbit, where each action triggers a transaction, highlighting Fuel’s real-time confirmation speed. The post emphasized: “Real-time is here, and it’s never looked better.” Links to the testnet and mainnet were included.
Technical Details: Another Twitter post explained how Fuel achieves confirmation speeds faster than the blink of an eye (~100 ms). Transactions receive a “soft” pre-confirmation in 6–51 ms via a P2P network, with final settlement on Ethereum occurring later. This eliminates delays typical of other L2s, providing a web2-like instant response. The technology leverages parallel UTXO processing, a register-based virtual machine, and P2P pre-confirmations while maintaining L1 security.
AMA Session: Fuel announced and held an AMA session on Twitter, focusing on real-time confirmations and their impact on users. The community was invited to submit questions and topics for discussion.
Token Purchase Program: The Fuel Network Foundation reported successfully completing 50% of its $1M FUEL token purchase program, acquiring $500K worth of tokens. All tokens were transferred to a public address on Ethereum mainnet. The program, initiated earlier, involves weekly purchases of $250K over four weeks to replenish the ecosystem treasury.
Conclusion: During the week of May 5–11, 2025, Fuel made a significant leap forward by introducing real-time technology that removes blockchain speed barriers. The demonstrations, AMA, and transparent financial strategy bolster community trust and highlight the project’s ambitions within the Ethereum ecosystem.
Weekly #2 (May 12-18, 2025)
Weekly Highlights
Welcome to the latest weekly roundup of Fuel Network’s developments! From groundbreaking infrastructure advancements to developer tools and ecosystem growth, here’s a concise summary of what happened during May 12–18, 2025.
1. Decentralized Sequencer Launched
Fuel Network, in collaboration with Simply Staking, introduced its decentralized sequencer, addressing the centralization bottleneck in most rollups. Unlike traditional setups relying on a single sequencer, Fuel distributes transaction ordering across multiple validators, ensuring:
No single point of failure: The rollup continues even if a validator goes offline.
Censorship resistance: No single entity can block transactions.
MEV democratization: A planned MEV auction system will return value to FUEL token holders.
Regulatory compliance: Reduced reliance on centralized entities.
Technical Highlights:
Built on Cosmos SDK with a modular architecture bridging Ethereum and Fuel.
Minimal hardware requirements for validators (4 CPU cores, 8 GB RAM, 200 GB disk).
FuelStreamX, a temporary multi-signature settlement system, will transition to zero-knowledge proofs.
Transparent transaction processing with Ethereum event prioritization and validator consensus.

Weekly #3 (May 19-25, 2025)
Weekly Highlights
1. Fuel Ignition Mainnet Upgraded (v0.41.9)
On May 14, 2025, the Fuel Ignition mainnet was successfully upgraded to fuel-core v0.41.9. This release includes multiple performance improvements and new protocol capabilities.
New Features
Updated P2P Protocol Format Nodes now communicate using a more efficient format, improving error handling and network stability.
Transaction Expiration Policy Transactions now have a defined lifespan. If they aren’t processed within a set time, they expire automatically—freeing up network resources and avoiding congestion.
Support for ZK Opcodes (ecop, epar) FuelVM can now verify Groth16, Plonk, and FFlonk proofs natively. This adds foundational support for zk-enabled applications and privacy-preserving smart contracts.
Dynamic Gas Pricing Based on Ethereum DA Costs Transaction fees are now partially influenced by the cost of Ethereum data availability (DA). This ensures economic alignment and sustainable network operations.
Portable Database Backup and Restore Node operators can now easily create and restore backups for improved node management.
Fixes and Optimizations
DA Relayer Optimization Reduced redundant queries to Ethereum, improving DA efficiency and reducing load.
GraphQL and Gas Pricing Enhancements Improved performance and accuracy of GraphQL queries and gas calculations.
Faster Data Access with SeqLocks SeqLocks now enable concurrent, low-latency access to shared data—improving node throughput.
Better Compatibility and Compression Fixed backward compatibility issues and improved compression for Ethereum DA payloads.
Enhanced Metrics and Monitoring New observability tools have been added for better tracking of node and network health.
2. Fuel Token Buyback Program Update
On May 15, 2025, the Fuel Network Foundation announced the continuation of its FUEL token buyback program.
✅ The initial $1M buyback has been completed—all tokens were moved to a public Ethereum address.
🔁 A new phase began on May 19, with $250K in weekly buybacks planned over a 3-week period.
📊 Program outcomes will be reviewed after the cycle ends.
Details and discussions are available on the Fuel Forum.
3. Native Assets on Fuel
On May 21, 2025, the Fuel team highlighted the advantages of native asset support in Fuel’s UTXO-based model.
Key Highlights:
No Token Approvals Required Unlike Ethereum, all assets on Fuel are native—no contracts or approvals needed, reducing security risks.
Atomic Multi-Asset Transfers Easily send multiple assets (e.g., 1 ETH, 250 USDC, and 5000 game tokens) in one transaction, with a single signature and one fee.
Simplified UX and Safer Code Native assets reduce both the number of user interactions and attack vectors.
Efficient Mass Operations Example: payroll distribution in USDC and company shares within a single atomic transaction.
4. FuelVM Performance Deep Dive
On May 22–23, 2025, the team shared a detailed look into FuelVM, the execution engine powering the Fuel network.
What Makes FuelVM Stand Out?
Register-Based VM Architecture Inspired by modern CPUs like ARM and RISC-V, FuelVM uses a register model (not a stack like EVM), leading to significant speed improvements.
UTXO-Based State Management Unused outputs are discarded, keeping the state minimal. Each output is uniquely identified by a 32-byte ID.
Parallel Execution with Access Lists FuelVM uses access lists to identify non-overlapping state changes. This allows multiple transactions to run in parallel—achieving up to 21,000 TPS per M4 core.
No State Bloat Predicates and scripts leave no permanent trace. Large data is stored as NFT-like packets and unpacked only when needed, minimizing on-chain bloat.
Real-World Applications

Weekly #4 (May 26-01, 2025)
Weekly Highlights
Fuel Embraces EigenDA for Scalable Data Availability
May 28, 2025 — Fuel Ignition transitioned from Ethereum DA to EigenDA, a high-throughput, low-cost data availability layer built on Ethereum.
Why It Matters:
Massive Scalability: EigenDA enables up to 150,000 TPS through parallel transaction execution across CPU cores.
Lower Costs: DA via EigenDA is significantly cheaper due to restaked ETH instead of calldata gas fees.
Modular Architecture: Separating execution (FuelVM) and DA allows for optimized performance and flexibility.
Developer Ready: Teams are encouraged to use the Sway language to build high-performance applications on Fuel.

Solving the DA Cost Challenge
May 29, 2025 — Fuel released an in-depth explanation on how high DA costs during network congestion affect transaction fees.
Key Takeaways:
EigenDA delivers stable fees and scalability:
15 MB/s throughput (mainnet)
Up to 100 MB/s planned
DA is cheaper because it leverages restaked ETH, not calldata.
Fuel joins other modular chains (like Mantle, Polygon CDK) in optimizing by decoupling execution and data availability.

Tackling State Bloat with UTXO & FuelVM
May 26, 2025 — In a new thread, Fuel addressed the blockchain state bloat issue—where increasing state size leads to slower performance and higher costs.
Fuel’s Solution:
UTXO Model: Eliminates the need for contracts to manage assets.
Predicates: Enable complex spend conditions without persistent state.
Native Multi-Asset Support: Assets are built-in, not wrapped contracts.
This results in:
Minimal state growth
Faster, cheaper transactions
A safer and simpler UX
