Summary

Cryptographic FIFO sequencing at microsecond resolution.

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.
