How RFC 18 Lets DoubleZero Match Traffic to the Right Links

Edge feeds need speed. Unicast needs bandwidth. RFC 18 lets DoubleZero's network give each what it needs, onchain. Why This Matters DoubleZero is a physical network assembled from links contributed by many operators. Those links are not uniform. They differ in latency, in bandwidth, and in what they are good for: a short low-latency metro hop is a different resource from a thin, high-latency intercontinental long-haul. A network that routes everything down a single lowest-latency topology sen

Proving Location with Physics: Geolocation Verification on DoubleZero

Location on the internet is a best-effort guess. IP geolocation databases have somewhere between 50–70% city-level accuracy under good conditions, and worse in the cloud and colocation environments where most production infrastructure lives. GPS is precise but requires hardware access to datacenter rooftops that simply isn't practical at scale. Self-attestation, or where an operator independently reports where they are, is trivially, fakeable and offers no assurance for compliance or governance.

Making Shred Propagation Observable: The DoubleZero Edge Scoreboard

Scoreboard is a new, highly dynamic observability tool that benchmarks shred delivery speed across the DoubleZero protocol and other shred providers. This transparency supports DoubleZero Edge, a new platform on the DoubleZero network, delivering market-data primitives at institutional speed. This Scoreboard, along with other tools across a public-facing performance dashboard at data.malbeclabs.com, offers real-time views of overall network performance, foregrounding Malbec Labs’ commitment to
