Migration from boost to std-library equivalents and removal of unreachable
code paths. Touches infrastructure only — no consensus rule or wallet
serialization changes.
Dead code removed:
- IRC bootstrap (irc.cpp/h, 417 lines): orphan from pre-Tor era, no callers.
- Alert system (alert.cpp/h + sendalert RPC + Qt UI signal, ~500 lines):
retired post-V5 fork; old peers' alert messages now hit the unknown-cmd
default branch, logged + ignored.
- Legacy P2P handlers in main.cpp: "checkpoint" (already a no-op stub since
V5 fork master-key removal), "checkorder"/"reply" (2010-era Receive-by-IP
feature), plus their unused supporting structures (CRequestTracker,
PushRequest overloads, mapRequests/cs_mapRequests, mapReuseKey).
- Unreachable RPCs clearwallettransactions and scanforalltxns (~175 lines):
defined in rpcwallet.cpp but never registered in the dispatch table.
- Stale -alertnotify CLI help text (option was advertised but never wired).
boost::filesystem -> std::filesystem (C++17):
- 30 source files, 5 headers. namespace fs = boost::filesystem swapped to
namespace fs = std::filesystem; boost::filesystem::ifstream/ofstream
replaced with std::ifstream/ofstream (path-aware in C++17);
fs::system_complete -> fs::absolute; boost::filesystem::filesystem_error
-> std::filesystem::filesystem_error.
- Build system: dropped Boost::filesystem from link libs and Boost
components; PCH includes updated.
- Added explicit <filesystem> includes where types were previously
available only transitively (db.h, rpcblockchain.cpp).
boost::thread -> std::thread (12 files):
- sync.h CCriticalSection/CWaitableCriticalSection now alias
std::recursive_mutex/std::mutex. boost::unique_lock and
boost::condition_variable / boost::mutex::scoped_lock swapped to std
equivalents; sync.cpp boost::thread_specific_ptr -> thread_local
std::unique_ptr.
- init.cpp boost::thread_group rewritten as std::vector<std::thread> with
manual join loop. boost::thread::hardware_concurrency ->
std::thread::hardware_concurrency.
- main.cpp/wallet.cpp -blocknotify/-walletnotify shell-out threads now use
std::thread(...).detach() — fixes a latent bug where modern boost::thread
destructor would call std::terminate on the joinable thread.
- util.cpp NewThread now catches std::system_error.
- No interruption_point/interrupt usage anywhere — pure mechanical swap.
boost::chrono / boost::posix_time -> std::chrono (3 of 5 files):
- util.h: MilliSleep, GetTimeMillis, GetTimeMicros rewritten on std::chrono
(system_clock for epoch math, sleep_for for delays).
- snapshotnet.cpp: sleep_for swapped.
- DoS_tests.cpp: timing harness uses steady_clock.
- Skipped: rpcdump.cpp (boost::posix_time::time_input_facet has no clean
std::get_time equivalent) and qt/qtipcserver.cpp (locked to
boost::posix_time by boost::interprocess::message_queue::timed_receive).
Other housekeeping:
- Dropped unnecessary "using namespace boost;" from txdb-leveldb.cpp,
txdb-rocksdb.cpp, walletdb.cpp, db.cpp (verified no unqualified boost
names in those TUs).
- Removed unused extern declaration for clearwallettransactions.
Build fixes for non-unity builds on MinGW64/GCC 15:
- net.cpp: dropped stale #include "irc.h".
- addrman.cpp + main.cpp: explicit <cmath> include for sqrt/pow (was
arriving transitively via boost headers).
- rpcblockchain.cpp + init.cpp: defensive #undef STRICT/ADVISORY/PERMISSIVE
since windows.h macros collide with the Checkpoints:: enum values when
std headers reorder include flow.
- tor_embed_hooks.cpp: triangles_tor_check_interrupted now polls fShutdown
instead of boost::this_thread::interruption_requested (we never used
boost interruption — the hook was always effectively a no-op).
- snapshotnet.cpp: fs::remove error handle uses std::error_code.
- serialize.h: added <ios> for std::ios::badbit/failbit (was relying on
transitive include via boost).
Note: unity builds currently fail on this branch due to std::byte (C++17)
colliding with COM 'byte' typedef from shlobj.h when 'using namespace std;'
from earlier files in the unity slice leaks into util.cpp's parse of
shlobj.h. Build with -DENABLE_UNITY_BUILD=OFF (the default).

The seeds.cryptographic-triangles.org endpoint uses Caddy with auto-TLS,
so the daemon's seed fetcher now connects over HTTPS (port 443) using
OpenSSL instead of plain HTTP (port 80) which got a 308 redirect.
Also hardcodes 5 known onion seed addresses in onionseed.h as a fallback
for initial peer discovery when the HTTPS endpoint is unreachable.

reduce lock contention with 20K+ transaction wallets
- StakeMiner: continue instead of exit when CreateNewBlock fails
- Wrap all NotifyTransactionChanged/NotifyAddressBookChanged signal
emissions in try/catch to absorb stale slot exceptions
- Add -zapwallettxes flag: strips all tx records from wallet.dat
keeping only keys, then rescans blockchain to rebuild history

Replace per-transaction CTxIndex spent tracking with per-output UTXO
database (CUtxoEntry). ConnectBlock writes/erases UTXOs as blocks are
processed. FetchInputs reads directly from UTXO DB instead of
deserializing full transactions from disk.
Persist nChainTrust in block index (dbformat v3) to skip expensive
recalculation on every startup. Only populate setStakeSeen for last
500 blocks instead of all 2M+.
Lazy fallback to old CTxIndex path for databases upgrading from
pre-UTXO format - no big-bang migration required.
Fixes pre-existing bugs in introdialog.cpp (extra brace) and
net_bootstrap.cpp (namespace extern).

Every Triangles wallet is now a Tor node. Staking rewards subsidize
Tor infrastructure.
Core changes:
- Embedded Tor 0.4.9.6 as git submodule
- ConnectNode rejects all non-.onion peers
- Tor failure is fatal - wallet requires Tor to operate
- All proxies forced through embedded Tor SOCKS
- Clearnet (IPv4/IPv6) disabled at startup
- HTTP seed fetch routes through Tor proxy (removed boost::asio dep)
- Merged PoW cleanup: -623 lines of dead mining code
- Stripped dead LEGACY/MIXED bootstrap modes from net_bootstrap
- RPC getnetworkinfo reports tor_native mode
Tooling:
- scripts/bump-version.sh syncs version across all 17+ files
- Version bumped to 5.6.0 across all packaging manifests

- Hardcoded DNS3 (74.208.167.19), DNS2 (194.233.88.206), and Contabo (100.98.123.59) as fixed seeds
- Nodes will automatically connect to these on first run
- No manual addnode configuration needed
- Full mesh network connectivity built into the code
LookupHost expects std::vector<CNetAddr>& but was passed a single
CNetAddr, breaking compilation on all platforms.

Replace all hardcoded seed addresses (onion, clearnet, DNS) with a
dynamic HTTP-based seed list fetched from seeds.cryptographic-triangles.org
on startup. New getseedlist RPC exposes known .onion peers from the
address manager for a collector script to publish.
Any wallet that comes online with an onion address is automatically
discovered by peers via P2P addr exchange and appears in the seed list
within minutes. No binary rebuilds needed when addresses change.

Fixes multiple concurrency bugs exposed during shutdown when Tor proxy
connections are failing:
- Reorder shutdown: stop network threads before destroying Tor V3 services
- Make RPC listener responsive to fShutdown (poll_one+sleep vs blocking run_one)
- Wrap StopRequests() in try/catch and drain io_service on exit
- Fix leaked CNode AddRef in ThreadSocketHandler2 and ThreadMessageHandler2
(return→break so Release loop executes)
- Guard vNodes.size() read with cs_vNodes lock (data race)
- Guard Qt UI signal callbacks with fShutdown check (use-after-free)
- Add cs_vNodes lock in CNetCleanup global destructor
- Force-disconnect remaining nodes in StopNode() after threads stop
- Make Tor maintenance thread sleep in 500ms intervals for prompt shutdown

Peer connectivity (small network optimizations):
- Reduce hardcoded seed fallback delay from 30s to 10s
- Reduce peer retry interval from 600s to 120s
- Lower staking minimum peers from 3 to 1
- Relay addr messages to all connected peers instead of just 2
UI responsiveness:
- Add progress reporting to ScanForWalletTransactions (every 10K blocks)
- Use TRY_LOCK in WalletModel::pollBalanceChanged to avoid blocking UI
- Use TRY_LOCK in TransactionTablePriv::refreshWallet with retry
Auto-bootstrap:
- Add bootstrap.h/cpp with HTTP download via boost::asio
- On first run, prompt user to download blockchain snapshot from
bootstrap.cryptographic-triangles.org directly into data directory
- Downloads filelist.txt manifest then each file with progress dialog
- Falls back to IP 194.233.88.206 if DNS fails
- Gracefully continues to P2P sync if bootstrap unavailable

Major sync performance overhaul:
- Assumevalid: skip FetchInputs/ConnectInputs for blocks below
checkpoint (2,186,940). Only write txindex entries. Eliminates
millions of LevelDB reads during initial sync.
- Skip SyncWithWallets during IBD with automatic post-IBD wallet
rescan from genesis and SecureMsg chain scan.
- Skip wallet best-chain locator update during IBD so restarts
trigger proper rescan.
- Remove send/receive buffer limits (were 1MB/5MB, now unlimited).
The 1MB send buffer was the root cause of ~180 block stalls -
ProcessMessages stops reading when nSendSize >= SendBufferSize().
- Reduce IBD pipeline batch from 500 to 100 blocks for faster
re-requesting with near-instant block processing.
- Seed getblocks limit raised to 20000 during IBD (was 500).
- Faster message handler polling during IBD (10ms vs 100ms).

Adds CTorProcess which finds and launches an external Tor binary as a
subprocess, providing a SOCKS5 proxy on port 19099 and a v3 hidden
service on port 24112. The wallet auto-detects Tor from common install
locations or the app directory. Falls back gracefully to clearnet-only
if Tor is not found. Also fixes Tor-only network restriction that
blocked IPv4/IPv6, and bumps version to 5.1.7.

Critical fix: revert initial sync from getheaders back to getblocks.
The headers-first change (05b1fd1) broke chain continuation — after
downloading the first 2000 blocks, fresh nodes would stall because
the getheaders path has no orphan-based continuation mechanism.
The getblocks/inv/orphan cycle is required for full chain sync.
Also adds getblocks fallback to the headers handler so if headers
are used via other paths, sync still continues.
Other changes:
- Extract REST API into separate rest.cpp/rest.h
- Add REST rate limiting and CORS support

Startup optimization (fixes multi-minute hang on 2M+ block chain):
- Skip computing SHA-256 stake modifier checksum for blocks below last
checkpoint (was doing 2M+ unnecessary hashes on every startup)
- Reduce default -checkblocks from 2500 to 50 (disk read savings)
- Add progress percentage reporting during block index load
Headers-first sync (faster initial sync):
- Switch initial sync from getblocks to getheaders protocol
- Add PushGetHeaders and headers message handler in net/main
- Downloads 80-byte headers first, then requests blocks — allows
the node to learn chain structure before downloading full blocks
Address-index accelerated wallet rescan:
- New ScanForWalletTransactionsFromIndex() uses address index to find
only transactions touching wallet keys (skips scanning every block)
- Follows spend chains to find related transactions
- Falls back to full scan if index unavailable
- Track index sync state with addressIndexBestChain/StartHeight in LevelDB
