Gattaca Launches Ethereum Consensus Client Silver with Sub-10ms p99 Latency

ChainCatcher report: Blockspace infrastructure company Gattaca has announced the launch of Silver, an open-source Ethereum consensus client. The company operates the Ethereum block builder Titan Builder and the relay Titan Relay. Gattaca states that Silver was built from scratch with the goal of supporting shorter slots and post-quantum security while maintaining decentralization, censorship resistance, privacy, and security. Silver is currently in alpha stage, with audits and final testing yet to be completed. Gattaca claims that Silver’s state transition function has a p99 latency of less than 10 milliseconds—approximately 10 times faster than other clients. During a mainnet window from October 17 to 20, 2026, Silver, Prysm, Lighthouse, and Grandine processed the same 20,300 canonical blocks. Silver’s median block processing latency was 6.5 milliseconds, with a p99 of 9.5 milliseconds; the slowest block in the sample took 17.8 milliseconds. The next lowest median latency was 33.5 milliseconds, and the next lowest p99 was 91 milliseconds. All four clients ran as super-nodes, subscribed to all 64 attestation subnets, and hosted all 128 data columns, using the execution client ethrex v29.0.1. The above comparison used consensus processing metrics available to each client and excluded execution client processing time. Silver is built on Gattaca’s Flux framework, utilizing six bound CPU cores for parallel processing, and includes a low-latency peer-to-peer network, a state hashing library, formally verified BLS and KZG cryptographic libraries, and a node cluster for slashing protection. In another comparison, super-nodes—compared to default configurations—had to verify approximately 32 times more attestations and about 16 times more KZG proofs, yet block processing latency and resident memory remained in similar ranges.
