[5.4.9.11], 2026-03-04, testnet pre-release

This is a testnet-only pre-release (5.4.9.0 → 5.4.9.11) targeting block v14 mandatory activation on testnet at height 3126500. It is not intended for mainnet deployment; its purpose is to validate all v14 consensus changes before a coordinated mainnet hard fork. Mainnet nodes should not upgrade to this version.

The headline consensus change in this release is block v14, which activates three interdependent features: BIP65 (OP_CHECKLOCKTIMEVERIFY), BIP112/BIP68 (OP_CHECKSEQUENCEVERIFY and sequence-locked inputs), and Hash Time-Locked Contract (HTLC) support via the new createhtlc, claimhtlc, and refundhtlc RPCs. Block v14 also activates v3 beacons, which require a cryptographic BOINC account ownership proof (RSA-SHA512 signature issued by the BOINC project server) before a beacon is accepted, closing the historical gap where anyone who knew a CPID could advertise a beacon for it. (This historical gap was closed by the verification code process required for beacon v2, which has been used since Fern, but the verification code process is very inconvenient, especially new crunchers.) New beaconauth and advertisebeaconv3 RPCs support the v3 beacon flow, and a dedicated GUI wizard page guides researchers through the process.

Block v13 was made mandatory on testnet at height 2870000 during this release cycle. It activates a broad set of consensus features, much of whose infrastructure was built in the 5.4.6.0 release but gated behind the v13 block version:

  • Mandatory sidestaking: Protocol-enforced sidestake allocations (e.g. to the Gridcoin foundation) via administrative contract, validated in the block reward claim checker, with up to 4 mandatory sidestake outputs on the coinstake transaction. The sidestake registry, GUI management interface, and listmandatorysidestakes RPC were introduced in 5.4.6.0 (#2704).
  • Superblock v3 contracts carrying per-project all-CPID total credit data, required to support automated greylisting.
  • AutoGreylist: Automated greylisting of unresponsive BOINC projects based on Zero Credit Days (ZCD) and Whitelist Activity Score (WAS), with scraper convergence integration, GUI greylist state display, and an auto-greylist-override contract type. The system has received significant refinement since initial activation: flutter fixes for scraper quiescent periods, a benefit-of-doubt fix, removal of redundant fields from history output, and several crash and correctness fixes.
  • Changeable magnitude unit and magnitude weight factor: Configurable via protocol entries (administrative contracts with keys magnitudeunit and magnitudeweightfactor), enabling the network to adjust the research emission rate and the ratio of magnitude-to-balance weight in voting without a hard fork (#2781).
  • Enhanced constant block reward (CBR): Refactored GetConstantBlockReward with a ceiling raised to 500 GRC (from 20 GRC), controllable via protocol entry (blockreward1). Also corrected Active Vote Weight (AVW) computation for balance-only polls (#2781).
  • Contract payload version upgrades: Project contracts advance from v2 to v3, protocol and scraper contracts from v1 to v2, and voting, claim/MRC, and beacon contracts from v2 to v3. These version bumps enable the new payload formats required by several of the above features and by v3 beacons (which are further gated behind v14).

The build system has been thoroughly modernized. Autotools (configure.ac, Makefile.am) have been removed entirely; CMake is now the sole supported build system. Qt6 is now supported (alongside Qt5), Linux Flatpak packaging with CI/CD artifact publication is available, official Docker container images (headless and GUI) are published, macOS DMG packaging is fixed and an Intel DMG CI build is added, Windows NSIS installer generation via CPack is supported, and Alpine/Musl Linux CI coverage is added. Boost 1.89+ and GCC 15 compatibility are addressed. A new ENABLE_DEBUG_LOCKORDER CMake option and improved lock-order diagnostic output aid concurrency debugging.

GUI improvements include a v3 beacon ownership proof wizard page, thin-space thousands separators in coin amounts, transaction type tooltips and Help menu documentation links, a fix for stale researcher status display after beacon activation or revocation, fractional-scaling support with Qt6, Unicode data directory path handling on Windows, BOINC data directory resolution when native and Flatpak BOINC coexist, and macOS quit-hang and DMG packaging fixes. The terminology "investor" is replaced throughout with "non-cruncher".
