Follow-up to the doc rebrand, addressing the previously out-of-scope legacy:
- Currency unit: strCurrencyUnits (chainparams.cpp) and CURRENCY_UNIT
(amount.cpp) "HUSH" -> "DRAGONX". Both are display-only (RPC help + metrics);
no logic comparisons, verified.
- depends mirrors: libsodium/boost/utfcpp fetched from git.hush.is/attachments;
repointed to canonical upstream (GitHub release / archives.boost.io / GitHub
tag) with the existing sha256 hashes verified to match those sources.
- Seeds: nodes_main.txt now lists the five node[1-5].dragonx.is IPs (DNS-resolved)
instead of Hush nodes; regenerated src/chainparamsseeds.h (was compiling Hush
seed IPs as the fixed fallback); generate-seeds.py header now says DragonX;
hush_seed_nodes.txt updated to DragonX seeds.
- Deleted Hush-history / wrong-for-DragonX files: contrib/snapshot/ (block-500000
Hush airdrop, ~10MB), notary_seeds.txt (Hush notaries; DragonX isn't notarized),
and the Hush emission scripts hush_supply, hush_supply_old, hush_halvings,
hush_block_subsidy_per_halving (hardcode Hush's 340000/12.5 economics).
Kept: hush_scanner (engine invoked by dragonx_scanner) and the "The Hush
developers" copyright headers (lineage credit).

nMinimumChainWork was defined in chainparams but never checked, and IsInitialBlockDownload
decided "synced" from tip timestamp/height alone -- so an eclipsed or bootstrapping node
could be fed a cheap low-work fake chain with recent timestamps and trust it. Reset the
stale mainnet floor (0x281b32ff3198a1 was ABOVE the live chain, would have bricked mainnet)
to the real chainwork at height ~3,100,000, and hold a node in IBD until its tip reaches the
floor. Gated to the DRAGONX symbol so ephemeral assetchains from the same binary are not
trapped in IBD; the check can only keep a node in IBD, never force it out (no false-sync risk).
Complements the header-flood fix (b9fdc7981): that stops invalid-PoW headers off the real tip;
this stops valid-but-cheap fake chains from a fake genesis.

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
In 3.10.4 release, Hush checkpoints were added as DragonX checkpoints, causing nodes to not sync and ban seeds and other nodes that updated. These are DragonX checkpoints from a synced node but need to be verified with others that have synced nodes.
Our code requires sapling activation at height 1 so we can simplify this function
which should lead to some performance improvements since it is called from many
places, including mining code.
