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
- Add CheckRandomXSolution() to validate RandomX PoW in nSolution field
- Add ASSETCHAINS_RANDOMX_VALIDATION activation height per chain
(DRAGONX: 2838976, TUMIN: 1200, others: height 1)
- Add CRandomXInput serializer for deterministic RandomX hash input
- Fix CheckProofOfWork() to properly reject invalid PoW (was missing
SMART_CHAIN_SYMBOL check, allowing bypass)
- Call CheckRandomXSolution() in hush_checkPOW and CheckBlockHeader
Without this fix, attackers could submit blocks with invalid RandomX
hashes that passed validation, as CheckProofOfWork returned early
during block loading and the nSolution field was never verified.
The build system supports using CC to control the C compiler
and CXX to control the c++ compiler used but src/cc was hardcoded
to use the binary "gcc". Now it respects the custom value of
$CC environment variable if it exists.
