Worked on the Syndica/sig repository to deliver a robust WebSocket subscription system for real-time Solana RPC notifications, focusing on both performance and reliability. Leveraged Zig for backend and concurrent programming, integrating a unified WebSocket and HTTP RPC server that supports lifecycle-driven notifications for slots, accounts, programs, logs, and signatures. Introduced a new runtime with SlotStateCache to optimize account caching and notification delivery, while enhancing startup logging and thread safety. Addressed health signaling by refining health checks to use processed slots, and improved CI stability through targeted test adjustments. Emphasized event-driven architecture, error handling, and efficient network programming throughout development.

Apr 1, 2026April 2026 (2026-04) performance summary for Syndica/sig. Delivered a comprehensive WebSocket subscription upgrade and health signaling improvements that materially increase real-time visibility and reliability for clients and operators. Key features delivered include a full WebSocket subscription suite (slotSubscribe, accountSubscribe, programSubscribe, logsSubscribe, signatureSubscribe) whose notifications are lifecycle-driven and ordered according to replay slot events. The runtime was rebuilt around a new Runtime + SlotStateCache, enabling efficient caching of modified accounts at slot freeze and improving the correctness and performance of processed/confirmed/finalized notifications. Startup logging was enhanced, bank creation notifications were improved, and thread-safety in the notification path was strengthened. Expanded encoding support (base58, base64, base64+zstd, jsonParsed, dataSlice) and added filters (dataSize, memcmp, tokenAccountState) while preserving zero-lamport tombstones and last-modified-slot metadata for accounts. Implemented end-to-end logsSubscribe and signatureSubscribe (Agave-compatible payloads) with associated tests and testnet validation. Adjacent architectural tweaks include getWithModifiedSlot in accounts DB and consensus cleanup to reduce stale code. Health reporting fix: getHealth now uses the processed slot for startup/catch-up comparisons, improving accuracy during initialization. Overall impact includes more reliable real-time notifications, improved health signaling during catch-up, and better-validated testnet behavior, delivering meaningful business value for operators and clients.
