Merges the HD wallet work and process-based I2P integration from the
SAMI-PC hd-wallet branch into v6 master. Conflict resolution keeps
v6 embedded I2P (CI2PEmbedded) as primary, includes process-I2P
files for reference, preserves FastImportBlockFile() from hd-wallet,
and keeps v6 version numbers (6.0.0) and wAddressStack Qt layout.
BIP152 Compact Blocks (main.cpp, net.cpp, protocol.h):
- SipHash-2-4 short IDs (48-bit) for transaction identification
- Compact block relay with mempool reconstruction
- Merkle root verification before acceptance
- Graceful fallback to full block on any mismatch
- Collision detection for ambiguous short IDs
RocksDB Column Families (txdb-rocksdb.cpp/h):
- 5 CFs: default, blockindex, txindex, utxo, addrindex
- Per-CF tuning: UTXO optimized for point lookups, addrindex for scans
- Backward-compatible: falls back to default CF for pre-migration data
- Prefix-based routing in ReadRaw/WriteRaw/EraseRaw/ExistsRaw
Fork Detector (main.cpp, net.cpp, net.h):
- Background thread checks local tip vs peer median every 60s post-IBD
- Alerts on divergence > forkthreshold (default 5 blocks)
- Optional auto-rebuild trigger on severe divergence
Cross-Network Tor↔I2P Discovery (net.cpp, init.cpp):
- I2P seed addresses loaded into addrman alongside onion seeds
- Address relay bridges .onion and .b32.i2p between networks
- IsI2PAddr/IsOnionAddr helpers for network-type detection
Configurable Outbound Connections (net.cpp, init.cpp):
- -maxoutboundconnections flag (range 4-32, default 8)
Mempool Fee-Priority Boost (miner.cpp):
- 2x fee weight in PoS block assembly for higher staking rewards
SAM v3 Direct Streaming (i2p/i2p_embedded.cpp/h):
- CI2PSamSocket class with full SAM v3 protocol
- SESSION CREATE + STREAM CONNECT handshake
- Factory method on CI2PEmbedded for native I2P connections
- SAM bridge readiness check in bootstrap loop
Triangles already has a node-identity signing system (getwalletaddr/walletaddr
in onion_v3.cpp:4793-4848) that lets peers cryptographically prove they own
their .onion address. The problem: that handshake only fires at startup, so
a long-running sync daemon that takes 12+ hours to bootstrap gets exactly ONE
discovery round at minute 0 — and then never asks again.
This commit wires the existing signing + discovery machinery into the main
peer-connection loop, not just startup:
* src/net.h: add nLastGetaddrTrigger + nSignedPeerBonus fields to CNode
* src/net.cpp: in ThreadOpenConnections2, when connected onion peers < 4
AND 5min cooldown elapsed, re-fire getaddr + getseederlist on every
connected .onion peer. getwalletaddr is left alone (it generates a new
receiving key per call; signed peers are cached 24h anyway).
* src/tor/onion_v3.cpp: when HandleWalletAddrResponse verifies a peer's
signature, set nSignedPeerBonus=1 so sync peer selection prefers them.
* src/syncmanager.cpp: signed-peer bonus used as tiebreaker in peer sort
(after reliability score, before blocks-delivered).
Why this matters: real-world from-zero sync of the Triangles chain took
~18 hours because only 2-3 of the 14 seed .onion nodes were reliably
reachable from any given Tor instance. With periodic re-discovery, the
daemon now has a chance to find the 12 others when the 2-3 drop.
Verified: built clean (15:59), test daemon climbed from 70,828 → 73,997+
at ~1.9 blk/s with new binary, SYNC-SIGN message confirmed firing.
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).

7 sync/relay optimizations for faster block propagation on Tor-only network:
1. Improved unsolicited block push: track nBestKnownHeight from inv/block
messages instead of static nStartingHeight, so peers that sync up
receive direct block pushes
2. Reduced redundant-request timeout from 20s to 5s for faster failover
3. Pipeline improvement: continuous download window refill after every
accepted block + refill interval reduced from 5000 to 500 blocks
4. Sendheaders (BIP 130-style): negotiate header-based block announcements
to save one round-trip vs inv->getdata->block
5. Compact block relay: send header + prefilled coinbase/coinstake + short
tx IDs. For typical PoS blocks (0-2 txs) this is the complete block
with no follow-up needed. Includes getblocktxn/blocktxn for missing txs
6. Adaptive peer timeouts: use rolling average latency (EMA 7/8) to set
per-peer request and stall timeouts instead of fixed constants
7. Dual-peer requesting during IBD: request each block from two peers
simultaneously, use whichever arrives first

- Add checkpoints through block 2,209,000 to lock canonical chain
- Ban peers on incompatible forks (no common blocks after 3 getblocks)
- Auto-checkpoint: finalize blocks at MAX_REORG_DEPTH to prevent deep reorgs
- Require 10% trust delta for side-chain reorgs (first-seen advantage)
- Add gencheckpoints RPC command for easy future checkpoint generation

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 C++11 literal-suffix warnings in util.h, net.h, and alert.cpp.
Required space between string literal and macro per C++11 standard.
No functional changes - formatting only.
Fixed missing braces in CNode constructor (net.h:327-329) that caused
PushVersion() to execute unconditionally for ALL connections instead of
only outbound connections.
This bug caused inbound peers (seed nodes) to:
1. Send version on connection (unintended)
2. Send version again when receiving peer's version (intended)
3. Trigger Misbehaving(1) on peer side for duplicate version
4. Get disconnected by peer (ProcessMessage fails → CloseSocketDisconnect)
Result: Seed nodes could only serve ~120 blocks before disconnect,
making sync nearly impossible.
Bump version to 5.2.1.

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).

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
