Each scanned block deep-copied the newest witness of every note with history to start that block's entry, although a block without shielded outputs changes no witness, and spent or pending notes never change theirs. A note's 100-entry list was 100 separate copies, mostly identical. The list now holds Arc-shared witnesses. The per-block duplicate is an Arc::clone, and Arc::make_mut copies the newest entry only for unspent, non-pending notes and only in blocks with at least one shielded output. Every entry is still written in full, so the file is unchanged, and a spend takes its own copy of the witness. A loaded wallet is not de-duplicated, so the saving builds up over the next 100 blocks. No output change: the saved bytes are identical; notes use less memory. With 1000 live notes x 100 witnesses (a 70 MB file), RssAnon after 100 blocks without outputs is 18 MiB instead of 189 MiB and such a block scans in 1.0 ms instead of 2.1-2.7 ms; when every block has an output, the live bytes stay about the same. The witness tests, the 1000-seed oracle and a differential run against the unmodified backend (every witness entry and the whole saved file after every operation; only the cleared lists and the chosen spend notes may differ) all pass, and the measured wallet saves to the same SHA-256 as with the old build.

Building
Quick Setup
The setup script detects your OS, installs all build dependencies, and validates your environment:
./setup.sh # Install core build deps (interactive)
./setup.sh --check # Just report what's missing
./setup.sh --all # Core + Windows/macOS cross-compile + Sapling params
./setup.sh --win # Also install mingw-w64 + libsodium-win

Build Steps
### Clone repository (if not already)
git clone https://git.dragonx.is/dragonx/ObsidianDragon.git
cd ObsidianDragon/
Windows Build
./build.sh --win-release
Release Build
./build.sh --linux-release # Linux release + AppImage
./build.sh --win-release # Windows cross-compile
./build.sh --mac-release # macOS .app bundle + DMG
./build.sh --clean --linux-release # Clean + Release
Running
-
Start dragonxd (if not using embedded daemon):
dragonxd -daemon -
Run the wallet:
cd build/bin ./ObsidianDragon
The wallet will automatically connect to the daemon using credentials from ~/.hush/DRAGONX/DRAGONX.conf.
Using Custom Node Binaries
The wallet checks its own directory first when looking for DragonX node binaries. This means you can test new or different branch builds of hush-arrakis-chain/hushd without waiting for a new wallet release:
- Build or download the node binaries you want to test
- Place them in the same directory as the wallet executable (e.g.
build/bin/) - Launch the wallet — it will use the local binaries instead of the bundled ones
Search order:
- Wallet executable directory (highest priority)
- Embedded/extracted daemon (app data directory)
- System-wide locations (
/usr/local/bin,~/dragonx/src, etc.)
This is useful for testing new branches or hotfixes to the node software before they are bundled into a wallet release.
Configuration
Configuration is stored in ~/.hush/DRAGONX/DRAGONX.conf:
rpcuser=your_rpc_user
rpcpassword=your_rpc_password
rpcport=21769
