# SFI Nodes * SFI Nodes serve as the foundational building blocks of the Singularity Finance Layer-2 (L2) blockchain. They play a crucial role in decentralisation, transaction validation and overall network security. By enabling the platform to maintain its integrity, SFI Nodes facilitate the scaling necessary to meet the demands of decentralised applications. The rollout of SFI Nodes will occur in phases, commencing with Verifier Nodes in Q1 2025, followed by the introduction of a fault proof mechanism. * The phased approach to deploying the Nodes infrastructure—from Verifier Nodes to Fault Proofs—represents a meticulously planned roadmap towards achieving full decentralisation. Initially, Verifier Nodes will provide an efficient validation mechanism. As the ecosystem matures, the introduction of Fault Proofs will enable permissionless validation and dispute resolution, ensuring the system remains trustless and secure. * Once the Fault Proof system is fully integrated, the network will be poised for further scalability by decentralising sequencers, thereby eliminating any centralised control points. This strategy effectively balances immediate scalability needs with the long-term objective of establishing a fully decentralised and trustless Layer-2 ecosystem. Detailed guidance on running the nodes will be released in Q1 2025, coinciding with updates on Optimism's feature rollout for the upcoming year. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
