Clearnet (SearXNG)

BlepoOS's clearnet layer aggregates results from the open web using SearXNG — the same architectural pattern as DuckDuckGo and Startpage, but operated as Empoorio community infrastructure.

Design

• Multiple SearXNG nodes — no single point of failure
• HTTP/JSON integration from the aephoron-blepoos Rust crate (the same crate serves the results page)
• HTTPS mandatory for all clearnet endpoints
• Fallback chain when a node is unreachable

Provider trait

BlepoOS uses a unified Provider trait in the monorepo:

// components/blepoos/src/lib.rs
pub trait Proveedor {
    fn buscar(&self, consulta: &str, categoria: Categoria, pagina: u32) -> Result<Respuesta, Error>;
}

Clearnet providers wrap SearXNG instances. Web3 providers use Tantivy. The merge layer combines both.

Privacy

• Queries are not logged for advertising profiles
• No Empoorio user analytics on search content
• Node operators see aggregated uptime metrics only (public /metricas page)

Multi-node roadmap

Phase	Goal
1.1	Single SearXNG node (blepoos.aephoron.com) — live
1.2	Configurable node list in browser settings
1.3	Community node registry on EmpoorioChain
1.4	DMS rewards for nodes meeting uptime SLOs

Fallback behavior

If the node does not answer the health probe (/healthz, remembered for one minute), the browser sends the same query to DuckDuckGo and tells the user once — search never hard-fails. The return to BlepoOS is automatic.
