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 This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.fermilabs.xyz/continuum/summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
