Nick Dodson: Fuel Labs – Modular Execution Blockchains

As crypto adoption increases, so does the pressing need for blockchain scalability. Monolithic blockchains provide data availability, consensus and execution on a single, base layer, which makes scaling them a difficult endeavour. Multiple layer-2 (L2) scaling solutions have been proposed to address computation and/or data availability, but they reach the same design bottlenecks: limited bandwidth, account state models, sequential transaction processing, etc. Modular blockchains separate the core functionalities, redesigning them as customisable building blocks. This allows for greater flexibility and scalability, adapting blockchain structure to its intended function.

We were joined by Nick Dodson, CEO and co-founder of Fuel Labs, to discuss modular execution layers and how they approach different aspects of blockchain design and scalability.

Topics covered in this episode:

• Nick’s background and founding Fuel Labs
• Why most blockchain designs are not scalable
• The vision behind Fuel Labs’ modular execution layer
• The difference between L2 roll-ups and modular execution layers
• Blockchain design philosophies and integrations
• UTXO and multi-thread parallel transactions
• UTXO vs. account model systems
• Fuel Labs’ own virtual machine (VM)
• Multiple native assets support
• Developer experience switching to Sway DSL
• Bridging to a settlement layer and interoperability
• Building on Fuel
