Overview

Archival node sync form zero state support, reduced block broadcasts apply latency (faster new blocks availability), faster archival blocks download, configurable liteserver rate limits, multiple performance optimizations.

Changelog

  • Added archive node sync from zero support
  • Improved archive downloads: peer pinning, cooldowns, retries, hedged downloads, and checkpoint backpressure.
  • Improved broadcast flow: hot masterchain/shard caches, delayed compressed decode, and multi-block pending queues per chain.
  • Added liteserver configurable rate limits: per-IP request limits, connection limits, keep-alive timeout.
  • Improved live sync latency with priority masterchain broadcasts and faster catch-up from cached full blocks.
  • Hardened state checkpoints: non-zero states now must be saved together with full block and proof artifacts.
  • State snapshots no longer persist state-only checkpoints without block artifacts.
  • Block history lookups now return only blocks with served-full artifacts.
  • Hardened block metadata validation against forged served-full flags and direct next refs.
  • Fixed checkpoint completion so older flushes do not drop newer applied states.
  • Optimized liteserver sendMessage, account proof cache, block data loading, and non-final state cell lookup.
  • Added configurable large-BOC read workers and persistent-state BOC batch size.
  • Reduced Pebble cell-store allocations by reusing write batches.
  • Improved liteserver errors parity with the C++ node.
  • Metrics now expose applied masterchain progress separately from persisted state.
  • Changed several defaults in config.
  • Updated tonutils-go.
