- Update compiler references from gcc-8 to gcc-15 across build system
(build-mac.sh, darwin.mk, Makefile_custom)
- Use system Rust (rustup) instead of bundled Rust 1.32.0 for librustzcash
to fix rlib linker incompatibility on macOS Sequoia
- Replace deprecated std::random_shuffle with std::shuffle (net.cpp,
transaction_builder.cpp, wallet.cpp)
- Fix -std=gnu17 -> -std=gnu++17 for C++ targets (libzcash, libhush)
- Fix nodiscard warning in glibcxx_sanity.cpp
- Replace deprecated OSMemoryBarrier with std::atomic_thread_fence in LevelDB
- Add -Wno-error=deprecated-declarations to CXXFLAGS for third-party headers
- Fix REMAINING_ARGS unbound variable in build.sh
- Add --disable-tests handling to build-mac.sh
- Update README with correct macOS build dependencies and instructions
Fresh-syncing nodes rejected the on-chain min-diff block at the
RANDOMX_VALIDATION activation height (2838976) because GetNextWorkRequired
computed the expected nBits from the preceding normal-difficulty blocks,
producing 469847994 instead of the on-chain 0x200f0f0f (HUSH_MINDIFF_NBITS).
This caused all seed nodes to be banned with "Incorrect diffbits" and the
node could never sync past that height.
Two changes:
1. GetNextWorkRequired (pow.cpp): Return nProofOfWorkLimit at the exact
RANDOMX_VALIDATION activation height, matching the on-chain diff reset.
2. ContextualCheckBlockHeader (main.cpp): Raise DragonX daaForkHeight to
RANDOMX_VALIDATION + 62000, covering the window where nBits was never
validated (diff reset at 2838976 through the attack at ~2879907).
Tested by invalidating block 2838975 and reconsidering — node re-validated
through the diff reset and attack window, syncing back to tip with zero
bad-diffbits rejections.
Bump version to 1.0.1.
Build release binaries inside an Ubuntu 20.04 Docker container
to produce executables with lower GLIBC requirements, compatible
with older Linux distributions.
- Add Dockerfile.compat (Ubuntu 20.04 base, full depends rebuild)
- Add .dockerignore to exclude host build artifacts from context
- Add --linux-compat flag to build.sh with Docker build/extract/package
- Strip binaries inside container to avoid root ownership issues
Minimal rebrand (see compliant-rebrand branch for full rebrand):
- Rename binaries: hushd/hush-cli/hush-tx → dragonxd/dragonx-cli/dragonx-tx
- Default to DRAGONX chain params without -ac_* flags (randomx, blocktime=36, private=1)
- Update configure.ac: AC_INIT([DragonX],[1.0.0])
- Update client version string and user-agent to /DragonX:1.0.0/
- Add chainparams.cpp with DRAGONX network parameters
- Update build.sh, miner.cpp, pow.cpp for DragonX
- Add bootstrap-dragonx.sh utility script
- Update .gitignore for release directory
Share single RandomX dataset across all mining threads:
- Add RandomXDatasetManager with readers-writer lock, reducing RAM from
~2GB per thread to ~2GB total plus ~2MB per thread for the VM scratchpad
- Add LogProcessMemory() diagnostic helper for Linux and Windows
