v0.3.0.0 — Legacy Remade

This is a mandatory hard-fork release. Nerva activates hard fork 13 (CryptoNight-Adaptive v6) at block 4,320,000 (approximately 21 July 2026, ~19:00 UTC). All node operators, miners, exchanges, and services must upgrade to v0.3.0.0 before that block to stay on the network.

What's New

Consensus — Hard Fork 13

  • CryptoNight-Adaptive v6 proof-of-work — 8 MB scratchpad and a randomized VM program, activating at block 4,320,000 (#101)
  • Revalidate the transaction pool at hard-fork boundaries (#103)

Performance

  • Optimized Keccak permutation, ported from Monero #8262 (#104)
  • assume-valid height to skip PoW verification for historical blocks during sync, cutting initial sync time (#93)

Platforms & Builds

  • Fully static musl Linux builds — portable, dependency-free binaries for x86_64, ARMv8, ARMv7, and i686 (#109)
  • iOS (arm64) build support, shipping a device + simulator wallet .xcframework (#99, #107)

Bug Fixes & Security

  • Lock the block cache in get_cna_v6_data to prevent a data race (#111)
  • Fix a 32-bit Windows crash, a block-cache use-after-free, and 32-bit AES-NI handling (#108)
  • Defer Ctrl-C handling off the signal context to prevent a FreeBSD coredump (#102)
