# Architecture - [Continuum Overview](https://docs-v2.fermilabs.xyz/architecture/editor.md): Continuum is a modular blockchain with separation of concerns - Sequencing, Execution, Consensus, and DA are handled at different levels of the stack. - [Proof of Sequence](https://docs-v2.fermilabs.xyz/architecture/sequencing.md): Proof of Sequence embeds transactions in a proof of elapsed time. It achieves verifiable fair ordering layer subject to VDF limits. - [Execution](https://docs-v2.fermilabs.xyz/architecture/execution.md): Fermi Trade runs on a custom execution stack built on soverign sdk - [ContBFT](https://docs-v2.fermilabs.xyz/architecture/contbft.md): ConfBFT is designed for consensus over deterministic blocks - [Security Properties & Risks](https://docs-v2.fermilabs.xyz/architecture/security-properties-and-risks.md): This page elaborates on the claimed security properties, as well as known risks, of the continuum model. --- # 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-v2.fermilabs.xyz/architecture.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.
