ERPC Improves Performance of Solana RPC and Geyser gRPC — Achieves P99 Latency Reduction of Approximately 200ms in Asia by Utilizing DoubleZero's Dedicated Fiber Network

ELSOUL LABO B.V. (Headquarters: Amsterdam, Netherlands; Representative Director & CEO: Fumitake Kawasaki) and ERPC, operated by Validators DAO, announce that they have implemented performance improvements in Solana RPC (HTTP / WebSocket) and Solana Geyser gRPC, achieving a P99 latency reduction of approximately 200ms, particularly in the Asia region.

This improvement is due to the integration of DoubleZero's dedicated fiber network into ERPC's infrastructure. As a result of implementation across all regions, the most significant improvement was observed in the Asia region, where the concentration of Solana validators is low and high-speed data distribution has been structurally challenging. Both the Tokyo and Singapore regions have recorded a P99 reduction of approximately 200ms, and similar improvements have been observed in the Sydney region, which is currently undergoing test operations. The Sydney region is close to public release.

Measurements were conducted using the RPC Benchmark published by ThorLabs, with comparisons made under conditions close to actual transaction load.

Why the Difference in the Asia Region — Solana's Network Structure and Geographical Constraints

The majority of Solana validators are concentrated in Europe, particularly Central Europe centered around Frankfurt, due to historical and economic reasons. In regions with a high density of validators, data propagation between nodes is completed with a small number of hops, resulting in low and stable communication latency.

On the other hand, the Asia region has fewer validators and is physically distant from the European validator concentration areas in terms of block data propagation paths. When routed via the public internet, this distance directly accumulates as latency. As the number of relay points along the path increases, so does jitter, leading to a decrease in communication quality stability.

This structural geographical handicap has made it difficult to secure a fast and stable environment for Solana development and operation in Asia.

DoubleZero — Dedicated Fiber Network Bypassing the Public Internet

DoubleZero is a dedicated fiber network specialized for blockchain validator communication. It propagates data between validators through independent, high-performance fiber links, bypassing public internet routes.

On the public internet, data passes through multiple relay points and is affected by congestion and route fluctuations. DoubleZero bypasses this route and achieves reduced latency and suppressed jitter by performing optimized route control over dedicated links. Furthermore, at the network edge, duplicate transactions and spam traffic are filtered by dedicated hardware, thereby reducing the processing load on validators and nodes.

ERPC has integrated this DoubleZero network into its infrastructure across all regions. In regions where validators are already densely concentrated, such as Europe and North America, the original communication conditions were already good, so the extent of improvement is relatively smaller. However, in the Asia region, where validator density is low and latency via the public internet was high, the effect of route shortening by dedicated fiber was direct and significant.

Significance for Solana Developers in Asia

This improvement offers substantial benefits not only to validator operators but also to all developers who are developing and providing Solana dApps in the Asia region.

Applications utilizing Solana access the network through RPC. The speed of Solana experienced by users—whether it's displaying wallet balances, sending and confirming transactions, updating DeFi positions, or minting NFTs—is determined by the RPC's response speed. A P99 improvement of 200ms directly translates into a noticeable increase in application speed.

Furthermore, similar improvements have been achieved in real-time data streaming using Solana Geyser gRPC. For use cases that subscribe to on-chain data changes in real-time—such as obtaining price feeds, monitoring account states, and tracking transactions—access from Asia can now expect response quality close to that of Europe.

Until now, ensuring a fast Solana development environment in Asia inevitably involved performance compromises due to geographical constraints. ERPC, by leveraging DoubleZero's dedicated fiber network, is structurally resolving this limitation. Moving forward, as numerous innovations emerge on the Solana chain from Asia, ERPC will support their scale from the infrastructure side.

High-Quality Infrastructure Supported by Epics DAO Validators

As of March 2026, the Epics DAO validator, which operates as the SWQoS endpoint and Epic Shreds distribution source for ERPC, has reached the 3rd overall position globally among all Solana validators (score 99.93). It continues to maintain this level of performance while holding approximately 200,000 SOL in active stake.

Improvements in validator performance directly translate into enhanced quality of SWQoS endpoints, increased speed of Epic Shreds distribution, and improved quality of Solana RPC. The current DoubleZero integration improvements are built upon this world-class validator-supported infrastructure.

The platform as a whole continues to accelerate, not just peaking at the time of purchase, but through both validator growth and infrastructure improvements—this is ERPC's structural strength.

Everything at Zero Distance — ERPC Platform's Integrated Environment

ERPC integrates all necessary services for Solana infrastructure within a single platform.

Solana RPC, Solana Geyser gRPC, Solana Shredstream (Epic Shreds), bare metal servers, high-performance VPS, ERPC Global Storage—all of these are connected via internal network paths, and communication between services does not pass through the public internet. By simply deploying on the platform, you gain the fastest communication conditions, optimized configurations, and Solana-specific tuning from the outset.

This DoubleZero integration is an infrastructure layer improvement that enhances the overall communication quality of the entire platform. The combination of ERPC's zero-distance design and DoubleZero's dedicated fiber network achieves an optimized communication environment not only for proximate communication within the platform but also for global data propagation paths.

SLV — Start Solana Operations with AI Agents

SLV is an AI Agent Kit for Solana developers. By setting up the environment with a configuration wizard and launching the AI Console, you can start operating Solana validators and RPCs using natural language.

By deploying an environment built with SLV on the ERPC platform, you can benefit from all infrastructure optimizations, including this DoubleZero integration, without additional configuration.

5 Consecutive Years of WBSO Approval

ELSOUL LABO has received approval for 5 consecutive years since 2022 under the Dutch government's R&D support program, WBSO. They continue to conduct research and development on Solana RPC infrastructure based on ultra-low latency and automation of validator placement and operation orchestration, with the results directly reflected in platform performance improvements.

The integration of next-generation network technologies like DoubleZero is an extension of this research and development. The results of R&D are cumulative, and the angle of improvement increases over time.

Next-Generation Option — AS200261 Solana-Specialized Data Center

ELSOUL LABO has been granted its own ASN (AS200261) by RIPE NCC and is proceeding with the establishment of a top-tier new data center specialized for Solana. In addition to a unified hardware configuration featuring the latest generation AMD EPYC 5th Gen, AMD Threadripper PRO 5th Gen (e.g., 9975WX), and NVMe 5th Gen, it will achieve optimal network route design through its own ASN.

It is scheduled to open this month and will serve as the foundation for further acceleration of the entire platform. The initial batch is already sold out by reservation, but subsequent batches will be offered in order of waitlist.
