# Summary Continuum is Fermi Labs’ cryptographic sequencing layer that produces publicly verifiable, microsecond-granularity FIFO orderings for any L1 or roll-up. Using a VDF-backed commit-reveal protocol, Continuum enforces ordering without centralized trust, making it the first practical “provably fair” sequencer for high-frequency DeFi. While tightly integrated with Fermi DEX, Continuum is chain-agnostic and can gate transaction flows for AMMs, roll-ups, and cross-chain bridges. ### Functionalities * Microsecond-Resolution Ordering – A pipelined Wesolowski VDF (FPGA-accelerated option) timestamps incoming commitments; reveals are validated on-chain, anchoring order in time. * Proof-of-Fair-Inclusion – Anyone can verify that a transaction’s position adheres to the sequencer’s emitted Merkle root, guaranteeing censorship-free inclusion or irrefutable fraud proof. * Cross-Chain Compatibility – Bridge adapters relay VDF proofs to EVM chains, the SVM, or any CosmWasm runtime, enabling uniform ordering across multiple venues. * DoS-Resilient Pacing & Slashing – Rate-limit windows prevent spam; mis-ordering or withholding reveal data burns sequencer stake. * Composable Hooks & Webhooks – Libraries for Solidity, Rust (Anchor), and Typescript let dApps gate state changes on Continuum proofs with two function calls. * Geo-Distributed Relayer Mesh – Public relayers buffer transactions, replicate sequencing proofs, and broadcast to multiple RPCs to mitigate single-relay failure. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.fermilabs.xyz/continuum/summary.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
