OrdexCoin Core vASSERT version

OrdexCoin with vASERT difficulty adjustment feature.

This repository contains the Docker-based build system and the source overlay (Ordexcoin-Core-vASERT-4790.zip) that applies branding and configuration changes on top of Bitcoin Core v25.0.

Build

Requires Docker. No other dependencies needed.

Linux

./build-docker-linux.sh

Output: build/ordexcoin-v25.0.0-linux-x86_64.tar.gz

Binaries: ordexcoind, ordexcoin-cli, ordexcoin-tx, ordexcoin-wallet, ordexcoin-util, ordexcoin-qt

Static build

Builds all dependencies from source (Boost, Qt 5.15, BDB 4.8, libevent, etc.) and links them statically. The daemon binaries have no external shared library dependencies beyond libc/libstdc++:

./build-docker-linux.sh --static
# or equivalently:
./build-docker-linux-static.sh

Output: build/ordexcoin-v25.0.0-linux-x86_64-static.tar.gz

Binaries: ordexcoind-static, ordexcoin-cli-static, ordexcoin-tx-static, ordexcoin-wallet-static, ordexcoin-util-static, ordexcoin-qt-static

Windows (cross-compile)

./build-docker-windows.sh

Output: build/ordexcoin-v25.0.0-windows-x86_64.zip

Binaries: ordexcoind.exe, ordexcoin-cli.exe, ordexcoin-tx.exe, ordexcoin-wallet.exe, ordexcoin-util.exe, ordexcoin-qt.exe, libordexcoinconsensus-0.dll

Notes

• First build downloads and builds all dependencies from source (Boost, Qt 5.15, BDB 4.8, etc.). Allow 1-2 hours for Windows, 30-60 minutes for Linux. Subsequent builds cache unchanged layers.

Patches Applied

All changes are applied by the Dockerfiles (Dockerfile.linux, Dockerfile.windows) on top of Bitcoin Core v25.0 baseline.

1. Backslash path normalization (extract-zip.py)

Root cause of initial build failure. The source overlay zip was created on Windows and uses backslash path separators (\). Python's zipfile.extractall() on Linux creates directories literally named build-aux\m4\ instead of build-aux/m4/. This causes:

• configure.ac calls ORDEXCOIN_QT_INIT and ORDEXCOIN_QT_CONFIGURE
• These macros are defined in ordexcoin_qt.m4 inside the zip
• But the file ends up at build-aux\m4\ordexcoin_qt.m4 (with backslash dir name)
• aclocal scans build-aux/m4/ (forward slash) and finds only the old bitcoin_qt.m4
• ORDEXCOIN_QT_INIT is never defined → PKG_CHECK_MODULES cascade failure

Fix: Replaced z.extractall() with a custom Python helper that normalizes \ → / during extraction:

for name in z.namelist():
    norm = name.replace('\\', '/')
    dst = os.path.join(outdir, norm)
    if norm.endswith('/'):
        os.makedirs(dst, exist_ok=True)
    else:
        os.makedirs(os.path.dirname(dst), exist_ok=True)
        data = z.read(name)
        with open(dst, 'wb') as f:
            f.write(data)

2. Config filename rename

util/system.cpp and util/system.h contain the constant BITCOIN_CONF_FILENAME which must produce ordexcoin.conf:

s/BITCOIN_CONF_FILENAME/ORDEXCOIN_CONF_FILENAME/g
s/\"bitcoin\.conf\"/\"ordexcoin\.conf\"/g

3. Datadir path

The default data directory is set via string literals in util/system.cpp. The bare-string patterns "/.bitcoin" and ".bitcoin" are replaced:

s|\"/\\.bitcoin\"|\"/\\.ordexcoin\"|g
s|\"\\.bitcoin\"|\"\\.ordexcoin\"|g

4. Branding / window titlebars

GUI window title bars, splash screen, and about dialog use the application name string:

s/\"Bitcoin Core\"/\"OrdexCoin Core\"/g
s/\"Bitcoin\"/\"Ordexcoin\"/g

Applied to Qt source files, translation files.

5. Symbol and identifier renames

Source-level identifiers to match the fork namespace:

• BitcoinUnits → OrdexCoinUnits
• BitcoinAmountField → OrdexCoinAmountField
• BTC → OXC (ticker symbol)
• BITCOIN_URI_BEGIN → ORDEXCOIN_URI_BEGIN
• bitcoin-util → ordexcoin-util (in help text)
• bitcoin-wallet → ordexcoin-wallet (in help text)

6. Binary name in error messages

User-facing error messages referencing the bitcoind binary name:

s/\bbitcoind\b/ordexcoind/g

7. Symlinks for renamed source files

The zip overlay renames many files (e.g., bitcoin.cpp → ordexcoin.cpp) but does not create symlinks for files that other build targets expect. Created explicitly:

ln -sf ordexcoin.cpp src/bitcoin.cpp
# and similar for headers, Qt files, locale .ts files

8. Locale translation symlinks

Translation .ts files were renamed to ordexcoin_*.ts but Qt's lupdate/lrelease searches for bitcoin_*.ts:

for f in src/qt/locale/ordexcoin_*.ts; do
    base=$(basename "$f" | sed 's/ordexcoin/bitcoin/')
    [ ! -e "src/qt/locale/$base" ] && ln -sf "$(basename "$f")" "src/qt/locale/$base"
done

9. Signed message magic string

The magic string used for signed message verification was renamed from Bitcoin Signed Message:\n to Ordexcoin Signed Message:\n to prevent cross-chain signature reuse.

10. Makefile.qttest.include ENABLE_TESTS wrapper

The zip file shipped a broken Makefile.qttest.include missing the ENABLE_TESTS conditional guard. Wrapped with:

if ENABLE_TESTS
... content ...
endif

11. Permission fixes for build scripts

The zip file lacks execute permissions on several scripts. Set explicitly:

chmod +x share/genbuild.sh
chmod +x depends/config.guess depends/config.sub depends/gen_id

12. "bitcoin-node" and RPC example references

Help text referencing bitcoin-node and bitcoin-cli in usage examples were updated to ordexcoin-node and ordexcoin-cli.

Verification

Both Linux and Windows binaries have been verified clean of user-facing branding residue:

• strings ordexcoind | grep "\.bitcoin" — only the legitimate BIP URL en.bitcoin.it remains
• strings ordexcoind | grep "\bBITCOIND\b" — no matches
• strings ordexcoind | grep "bitcoin\.conf" — no matches

The only remaining bitcoin strings in the binary are legitimate protocol references (addresses, transactions, BIP specification URLs, and copyright attributions), which correctly describe the underlying Bitcoin protocol that OrdexCoin implements.
