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 transparency with public information that is continuously updated, and explorable by anyone.

Scoreboard presents a performance story told across multiple layers of metrics across the physical network and DoubleZero protocol: 

• Head-to-head latency comparisons between existing Solana shred providers
• First arrival / win rate data, or what % of the time DoubleZero delivers shreds fastest, with a toggle between “edge leaders only” and “all slots” views
• Regional probe data from nodes in Frankfurt, Singapore, Amsterdam, Tokyo, London, Salt Lake City, and New York 

There is no singular data point that tells the story of DoubleZero, due to regional performance variations, but taken in whole, the Malbec Labs Scoreboard transparently illuminates the latency advantage, consistency, and quality of shreds at the data propagation level, not just the blocks. 

Head-to-head latency comparisons 

This dashboard competitively measures Edge leader shreds and Edge retransmit shreds, as well as other shred distribution services win rates, including Jito Shredstream, and Turbine, Solana’s native propagation mechanism, by slots across nodes. The goal of this page is to observe: when a validator sends a shred, which method delivers it first: DoubleZero multicast, Jito Shredstream, or the Turbine tree? 

Also at top of the page are the total number of active validators that are connected to DoubleZero that are publishing shreds via multicast as well as the total cumulative stake weight that those validators represent.

Network performance continues to improve with increased adoption. For interested validators, they can learn more about connecting and publishing at docs.malbeclabs.com.

Win Rate Data

As most know, when a validator is the designated leader for a slot, they are the one producing new blocks. DZ Edge delivers the raw block data faster in these measured scenarios, specifically during the slots where a DoubleZero-connected validator is leading. Of those slots, the win rate for DoubleZero Edge is typically ~90%.

As Solana has thousands of slots, and leadership rotates across all validators constantly, regional transmit groups are measured as well. 

DZ Edge Leaders populates first, showing a win rate percentage, or how often the node is the fastest path for market data across every opportunity it had to compete, when slots with the scheduled leader are publishing shreds to DZ Edge. This is combined across leaders and retransmits at the top of the page. By clicking into All Slots, DZ Edge is also visible alongside Jito Shredstream and Turbine at p95, or then 95th percentile of latency, when 95% of deliveries are faster across all observed slots.*

Regional Probe Data

The nuance of the physical network is why there is no single metric that captures the totality of the DZ Edge advantage. 

Data scrolls on a slot by slot basis, broken down by the nodes at left, with details about the slot leaders at right, showing who the leader is and who wins.

Each node can be opened to show IP address, geographic location, the pubkey of the validator that is running on each node and connectivity. 

Below the live feed, this view is expanded to display performance metrics comparing DZ Edge Win Rates to Jito Shredstream and Turbine per location at p50 (p95) latency scales, the median and a stress test perspective. 

Conclusion

On average, Solana leader shreds published via DoubleZero Edge reached recipients 6 milliseconds faster than with other shred distribution services in early testing. During periods of high block congestion or degraded network conditions, DoubleZero Edge delivers its most pronounced latency advantage. In these scenarios, it delivers shreds up to 20+ milliseconds faster in Europe, 80+ milliseconds faster in the U.S., and over 100 milliseconds faster in Asia.**

DoubleZero Edge, with the transparency of Scoreboard, provides independently verifiable, real-time shred delivery data. In a world where milliseconds determine outcomes, independently verifiable performance data matters.
