+# Triangles Codebase Cleanup Notes
+
+## Overview
+Systematic code quality improvements for the Triangles cryptocurrency codebase (v5.3.4+).
+
+**Goal:** Improve maintainability without changing behavior or breaking consensus.
+
+## Inventory
+
+### TODOs/FIXMEs Found (38 total)
+
+#### High Priority (Affects Safety/Correctness)
+- `rpcmining.cpp:263` - **Thread safety issue** in mapNewBlock (static variable, no mutex)
+- `walletmodel.cpp:249` - **Potential collision** in balance calculation
+- `smessage.cpp:863, 2219, 2373` - **File size limit** (files must be split if >2GB)
+
+#### Medium Priority (Encapsulation/Security)
+- `protocol.h:50, 100, 132` - Public members should be private (3 locations)
+- `wallet.h:378` - nOrderPos calculation should move elsewhere
+- `wallet.cpp:733, 1732` - Change output handling needs improvement
+- `rpcwallet.cpp:1474, 1513, 1569` - SecureString operator= missing (forced .c_str())
+
+#### Low Priority (Nice-to-Have)
+- `util.cpp:1322` - Disabled feature needs verification
+- `tor/tor_embedded.cpp:209` - Tor 0.4.9+ shutdown API upgrade
+- `init.cpp:442` - Remaining sanity checks (see Bitcoin issue #4081)
+- `rpcmining.cpp:232` - DRM comment (unclear what it means)
+- `smessage.cpp:*` - Various improvements (hash inclusion, thread safety, defaults)
+- `qt/*` - UI improvements (decrypt not supported, message filtering, OSX startup)
+
+#### External/Third-Party (Don't Touch)
+- `leveldb/*` - LevelDB library TODOs (upstream issues)
+
+## Code Quality Issues
+
+### Using namespace std (37 files)
+All in .cpp files - **this is fine for .cpp**, problematic only in headers.
+No headers have this issue, so **no action needed**.
+
+### Printf/Cout Usage (56 files)
+Most cryptocurrency code uses printf for early init/error handling before logging is available.
+**Review needed:** Check if these are legitimate early-init cases or should use LogPrintf.
+
+## Cleanup Plan (Safest → Riskiest)
+
+### Phase 1: Documentation & Comments ✅ SAFE
+1. Document all TODOs with context (why deferred, what's needed)
+2. Add function-level comments for complex logic
+3. Improve inline comments for clarity
+
+### Phase 2: Low-Risk Code Quality 🟨 MEDIUM RISK
+4. Fix compiler warnings (-Wall -Wextra)
+5. Add const correctness where missing
+6. Remove commented-out dead code
+7. Standardize code formatting (if inconsistent)
+
+### Phase 3: Functional Improvements 🟥 HIGH RISK (Skip for now)
+8. Fix thread safety issue in rpcmining.cpp (requires testing)
+9. Improve protocol.h encapsulation (may affect other code)
+10. Address >2GB file handling in smessage.cpp
+
+## Decisions
+
+### What NOT to Change
+- **Consensus code** - main.cpp (validation), kernel.cpp (PoS), miner.cpp (staking)
+- **Serialization** - Any READWRITE, serialize/deserialize code
+- **Protocol constants** - Network message types, version numbers
+- **Third-party code** - leveldb/, tor/, sph_types.h, xxhash/, lz4/
+
+### What's Safe to Change
+- Comments and documentation
+- Variable names (in non-consensus code)
+- Code organization (splitting large functions)
+- Logging statements
+- UI code (qt/)
+- RPC interface (as long as API contract preserved)
+
+## Initial Cleanup (2026-03-22)
+
+### Actions Taken
+1. Created this documentation file
+2. Created cleanup/desloppify branch
+3. Inventoried all TODOs/FIXMEs
+
+### Next Steps
+1. Add documentation comments to TODO items
+2. Review printf/cout usage patterns
+3. Check for compiler warnings
+4. Consider low-risk improvements
+
+## Notes
+- This is a Bitcoin-derived codebase, so many patterns follow Bitcoin Core conventions
+- Recent v5.3.x work already modernized to C++17 and removed Boost - good foundation
+- Code is generally well-structured; main improvements are documentation and minor cleanup

+# Triangles Cleanup Strategy - Safe Improvements
+
+**Branch:** `cleanup/safe-improvements`  
+**Goal:** Improve code quality without touching consensus-critical code
+
+## ✅ SAFE TO FIX
+
+### 1. Compiler Warnings (Non-Consensus)
+- **C++11 literal-suffix warnings** - Add spaces between literals and suffixes
+- **Unused variables/functions** - Remove dead code (verify not consensus-critical first)
+- **Deprecated-copy warnings** - Fix CScript assignment operator if safe
+
+### 2. Code Style Improvements
+- Remove `using namespace std` from headers (keep in .cpp files)
+- Standardize logging patterns
+- Improve code comments (remove unclear/misleading ones)
+- Add context to TODOs/FIXMEs
+
+### 3. Documentation
+- Add inline comments for thread safety concerns
+- Document collision vulnerabilities
+- Improve function/class documentation
+
+## ❌ DO NOT TOUCH
+
+### Consensus-Critical Code
+- **OpenSSL SHA256/RIPEMD160 usage** - Deprecated warnings OK, do not change
+- **BN_is_prime_ex** - Crypto library deprecation, leave as-is
+- **Hash algorithms** - Third-party libraries with warnings, consensus-critical
+- **Block validation logic** - Any code affecting block/transaction validation
+- **Merkle tree construction** - Core consensus
+- **Proof-of-Work/Proof-of-Stake** - Staking/mining algorithms
+
+### How to Identify Consensus Code
+- Files in `src/` related to: `main.cpp`, `main.h`, block validation, transaction validation
+- Anything in hash algorithm libraries
+- Cryptographic primitives
+- Network protocol message formats (version, serialization)
+
+## Incremental Testing Strategy
+
+1. **One warning category at a time**
+2. **Compile after each change**
+3. **Test basic functionality:**
+   - `trianglesd getinfo`
+   - `trianglesd getblockchaininfo`
+   - Verify block sync works
+4. **Commit incrementally** with clear messages
+
+## Warning Categories (From Build Output)
+
+```
+1. C++11 literal-suffix: ~20 instances (util.h, net.h, alert.cpp)
+2. OpenSSL deprecation: SHA256, RIPEMD160 (DO NOT FIX)
+3. BN_is_prime_ex: crypto library (DO NOT FIX)
+4. Deprecated-copy: CScript assignment (REVIEW CAREFULLY)
+5. Unused variables/functions: Various (SAFE IF NOT CONSENSUS)
+```
+
+## Branch History
+
+- Previous work: `cleanup/desloppify` (documentation improvements, merged to master)
+- This branch: Focus on safe compiler warnings and code quality
+
+## Verification Checklist
+
+Before pushing each commit:
+- [ ] Code compiles successfully
+- [ ] No new warnings introduced
+- [ ] trianglesd runs without errors
+- [ ] getinfo/getblockchaininfo work
+- [ ] No consensus-critical code touched
+
+---
+
+**Principle:** When in doubt, don't touch it. A clean codebase is worthless if the blockchain forks.

+# Embedded Tor Integration Guide for Triangles
+
+This guide explains how to compile Tor as a static library (`libtor.a`) and link
+it directly into the Triangles wallet binary so that every node automatically
+runs a Tor hidden service without needing an external Tor installation.
+
+## Architecture Overview
+
+```
+trianglesd / triangles-qt
+  ├── tor_embedded.cpp    ← calls tor_run_main() in a background thread
+  ├── tor_process.cpp     ← fallback: launches external tor binary (already works)
+  ├── onion_v3.cpp        ← V3 onion address generation / SOCKS5 proxy logic
+  └── libtor.a            ← aggregate static Tor library (built from official source)
+```
+
+When compiled with `ENABLE_TOR_EMBEDDED`, the wallet calls `tor_run_main()` from
+`tor_api.h` on a dedicated thread. This gives the wallet a SOCKS5 proxy on
+`127.0.0.1:19099` and a V3 hidden service on port 24112 (the P2P port).
+
+When compiled **without** the flag, `tor_embedded.cpp` falls back to the external
+`tor_process.cpp` which searches for and launches a system `tor` binary.
+
+## Step 1: Add Tor as a Git Submodule
+
+```bash
+cd /path/to/triangles
+git submodule add https://gitlab.torproject.org/tpo/core/tor.git src/tor/tor-src
+cd src/tor/tor-src
+git checkout release-0.4.9   # latest stable branch as of 2026
+```
+
+This puts the full Tor source at `src/tor/tor-src/`.
+Current imported checkout in this repo: `release-0.4.9` at commit `1442ca4`.
+There is also a helper build script at `src/tor/build-libtor.sh`.
+
+## Step 2: Build libtor.a
+
+Tor uses autotools. Build it as a static library:
+
+```bash
+cd src/tor/tor-src
+
+# Install Tor build dependencies
+sudo apt install autoconf automake libtool pkg-config \
+    libssl-dev libevent-dev zlib1g-dev
+
+# Generate configure script
+./autogen.sh
+
+# Configure for static library build (disable unneeded modules)
+./configure \
+    --enable-static-tor \
+    --disable-module-relay \
+    --disable-module-dirauth \
+    --disable-asciidoc \
+    --disable-manpage \
+    --disable-html-manual \
+    --disable-unittests \
+    --disable-tool-name-check \
+    --with-openssl-dir=/usr \
+    --with-libevent-dir=/usr \
+    --with-zlib-dir=/usr \
+    --prefix=/usr/local
+
+make -j$(nproc)
+```
+
+Or from the repo root:
+```bash
+./src/tor/build-libtor.sh
+```
+
+After building, the static libraries are in `src/tor/tor-src/`:
+- `libtor.a`
+- `src/lib/libtor-*.a` (multiple component libs)
+
+The header `src/feature/api/tor_api.h` provides the public C API:
+```c
+tor_main_configuration_t *tor_main_configuration_new(void);
+int tor_main_configuration_set_command_line(tor_main_configuration_t *cfg,
+                                             int argc, char *argv[]);
+int tor_run_main(const tor_main_configuration_t *);
+void tor_main_configuration_free(tor_main_configuration_t *);
+```
+
+## Step 3: Build Triangles with Embedded Tor
+
+### Linux (makefile.unix)
+
+```bash
+cd src
+
+# Point to Tor's built libraries and headers
+make -f makefile.unix \
+    USE_TOR_EMBEDDED=1
+```
+
+You may need to adjust the `-l` flags in the makefile depending on the exact
+library names Tor produces. Check `src/tor/tor-src/` after building:
+
+```bash
+find tor/tor-src -name '*.a' | sort
+```
+
+On the imported `release-0.4.9` checkout in this repo, the simplest working
+link path is the aggregate `libtor.a` plus the normal dependency libraries.
+
+### Windows (triangles-qt.pro)
+
+Add to `triangles-qt.pro`:
+```qmake
+qmake "USE_TOR_EMBEDDED=1" \
+      "TOR_SOURCE_ROOT=src/tor/tor-src"
+```
+
+Both build systems now default to:
+- source root: `src/tor/tor-src`
+- include path: `src/tor/tor-src/src/feature/api`
+- library path: `src/tor/tor-src`
+- embedded Tor library: `-ltor`
+
+On Windows, the imported Tor `0.4.9.5` build also needed:
+- `-llzma`
+- `-lzstd`
+- `-liphlpapi`
+- `-lshlwapi` (already linked by Triangles)
+
+## Step 4: Wire into init.cpp
+
+The global hooks `StartEmbeddedTor()` and `StopEmbeddedTor()` need to be called
+from `init.cpp`. Add these calls:
+
+### In AppInit2() (after network init, before starting node):
+```cpp
+#include "tor/tor_embedded.h"
+
+// Near the end of AppInit2, after network initialization:
+if (!StartEmbeddedTor()) {
+    printf("WARNING: Embedded Tor failed to start. .onion connectivity unavailable.\n");
+    // Non-fatal: wallet works without Tor, just no .onion
+}
+```
+
+### In Shutdown():
+```cpp
+StopEmbeddedTor();
+```
+
+## Step 5: Configure SOCKS Proxy for Outbound Connections
+
+After Tor starts, the wallet needs to route `.onion` connections through the
+SOCKS5 proxy. In `net.cpp`, after Tor is initialized:
+
+```cpp
+// If embedded Tor is running, use its SOCKS proxy for .onion addresses
+CTorEmbedded* tor = CTorEmbedded::GetInstance();
+if (tor->IsRunning()) {
+    // Set proxy for .onion connections
+    proxyType addrProxy(CService("127.0.0.1", tor->GetSocksPort()), 5);
+    SetNameProxy(addrProxy);
+}
+```
+
+## Runtime Flags
+
+The embedded Tor respects these command-line flags:
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `-notor` | false | Disable Tor entirely |
+| `-torsocks=PORT` | 19099 | SOCKS5 proxy port |
+| `-torhsport=PORT` | 24112 | Hidden service virtual port |
+
+## File Layout After Integration

+
+## Reference: How VERGE (XVG) Does It
+
+VERGE uses the same pattern. Their implementation is at:
+- `src/torcontroller.cpp` (~100 lines)
+- They use `tor_main()` (older API, pre-0.4.5)
+- Git submodule at `src/tor/` pointing to `release-0.4.8` branch
+- Build Tor as part of their `depends/` system
+
+Key difference: modern Tor (0.4.5+) uses `tor_run_main()` with a configuration
+object instead of raw `tor_main(int argc, char** argv)`.
+
+## Troubleshooting
+
+**Tor fails to bootstrap**: Check firewall rules. Tor needs outbound TCP to the
+Tor network (ports 80, 443, 9001, 9030).
+
+**Link errors with libtor**: Prefer the aggregate `libtor.a` from the top level
+of the Tor build tree. On the imported Windows/MSYS2 build in this repo, the
+minimal verified link set was:
+```
+-ltor -levent -lssl -lcrypto -lz -llzma -lzstd -lws2_32 -liphlpapi -lshlwapi
+```
+
+**OpenSSL version mismatch**: Both Tor and Triangles must link against the same
+OpenSSL version (3.x). If Tor was built against a different OpenSSL, rebuild it
+with the same `--with-openssl-dir`.

+# Triangles Bootstrap Server Setup - DNS2
+
+**For:** Krystie (@Krystie7777bot)
+**Server:** DNS2 (194.233.88.206) - Ubuntu
+**Date:** March 2026
+
+---
+
+## What This Server Does
+
+Your server is the **bootstrap server** for the Triangles network. When someone opens a fresh Triangles wallet:
+
+1. The wallet connects to `bootstrap.cryptographic-triangles.org` on **port 80**
+2. If that fails, it falls back to your IP directly: `194.233.88.206` on **port 80**
+3. It downloads `/filelist.txt` to see which blockchain files are available
+4. It downloads each file listed (mainly `blk0001.dat`, the entire blockchain)
+5. The user is now synced and ready to go
+
+Your IP is hardcoded in the wallet. If your server is down, new users can't bootstrap.
+
+Your server also runs the Triangles daemon so it doubles as a seed node on **port 24112**.
+
+---
+
+## Step 1: Install nginx
+
+```bash
+sudo apt update
+sudo apt install -y nginx curl
+```
+
+---
+
+## Step 2: Download the Daemon
+
+No building required. Download the pre-built Linux binary from GitHub:
+
+```bash
+cd /tmp
+curl -L -o trianglesd https://github.com/SamiAhmed7777/triangles_v5/releases/download/v5.3.7/Cryptographic-Triangles-v5.3.7-linux-x64-daemon
+chmod +x trianglesd
+sudo mv trianglesd /usr/local/bin/
+```
+
+Verify it works:
+
+```bash
+trianglesd --version
+```
+
+---
+
+## Step 3: Configure the Daemon
+
+```bash
+mkdir -p ~/.triangles
+
+RPC_PASS=$(openssl rand -hex 32)
+
+cat > ~/.triangles/triangles.conf << EOF
+port=24112
+listen=1
+maxconnections=125
+rpcport=19112
+rpcuser=trianglesrpc
+rpcpassword=$RPC_PASS
+rpcallowip=127.0.0.1
+server=1
+externalip=194.233.88.206
+addnode=74.208.167.19
+txindex=1
+daemon=1
+EOF
+```
+
+---
+
+## Step 4: Get the Blockchain Data
+
+OpenClaw will send you `blk0001.dat` (or a tarball containing it). Put it in `~/.triangles/`:
+
+```bash
+cd ~/.triangles
+# If you received a tarball:
+tar xzf /path/to/blockchain-data.tar.gz
+# Or if you received blk0001.dat directly:
+cp /path/to/blk0001.dat ~/.triangles/
+```
+
+After this step you should have:
+
+```
+~/.triangles/blk0001.dat
+~/.triangles/triangles.conf
+```
+
+Do NOT copy someone else's `wallet.dat` unless you intend to use that wallet.
+
+---
+
+## Step 5: Open Firewall Ports
+
+You need **two** ports open:
+
+```bash
+sudo ufw allow 80/tcp comment "Bootstrap HTTP server"
+sudo ufw allow 24112/tcp comment "Triangles P2P"
+sudo ufw enable
+sudo ufw status
+```
+
+Verify both show ALLOW:
+
+```
+80/tcp                     ALLOW       Anywhere        # Bootstrap HTTP server
+24112/tcp                  ALLOW       Anywhere        # Triangles P2P
+```
+
+Do NOT open 19112 (RPC).
+
+---
+
+## Step 6: Test the Daemon
+
+```bash
+trianglesd
+```
+
+Wait 10 seconds, then:
+
+```bash
+trianglesd getinfo
+```
+
+Look for:
+- `"blocks"` around 2,186,940 or higher
+- `"connections"` should become 1+ within a couple minutes
+
+If it works, stop it:
+
+```bash
+trianglesd stop
+```
+
+---
+
+## Step 7: Set Up the Daemon as a systemd Service
+
+```bash
+sudo tee /etc/systemd/system/trianglesd.service << 'EOF'
+[Unit]
+Description=Triangles Daemon
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=forking
+ExecStart=/usr/local/bin/trianglesd -daemon -datadir=/root/.triangles
+ExecStop=/usr/local/bin/trianglesd -datadir=/root/.triangles stop
+Restart=on-failure
+RestartSec=30
+TimeoutStopSec=120
+LimitNOFILE=65536
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+sudo systemctl daemon-reload
+sudo systemctl enable trianglesd
+sudo systemctl start trianglesd
+```
+
+If you're running as a non-root user, change `/root/.triangles` to `/home/youruser/.triangles`.
+
+Verify:
+
+```bash
+sudo systemctl status trianglesd
+trianglesd getinfo
+```
+
+---
+
+## Step 8: Set Up the Bootstrap File Server
+
+This is the main event.
+
+### 8a. Create the bootstrap directory and tarball
+
+```bash
+sudo mkdir -p /var/www/triangles-bootstrap
+
+# Create the compressed tarball from the blockchain data
+# Only blk0001.dat is needed - the wallet builds its own block index after download
+cd ~/.triangles
+tar czf /tmp/bootstrap.tar.gz blk0001.dat
+sudo mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/
+
+# Also create the legacy fallback files (for older wallet versions)
+sudo cp ~/.triangles/blk0001.dat /var/www/triangles-bootstrap/
+sudo tee /var/www/triangles-bootstrap/filelist.txt << 'EOF'
+blk0001.dat
+EOF
+
+sudo chown -R www-data:www-data /var/www/triangles-bootstrap
+```
+
+The wallet tries to download `bootstrap.tar.gz` first (compressed, faster). If that's missing, it falls back to downloading `blk0001.dat` directly using `filelist.txt`. After download, the wallet automatically imports the blocks and builds its own index.
+
+### 8b. Configure nginx
+
+```bash
+sudo rm -f /etc/nginx/sites-enabled/default
+
+sudo tee /etc/nginx/sites-available/triangles-bootstrap << 'EOF'
+server {
+    listen 80;
+    server_name bootstrap.cryptographic-triangles.org 194.233.88.206;
+
+    root /var/www/triangles-bootstrap;
+
+    location / {
+        try_files $uri =404;
+    }
+
+    send_timeout 600s;
+    keepalive_timeout 600s;
+}
+EOF
+
+sudo ln -sf /etc/nginx/sites-available/triangles-bootstrap /etc/nginx/sites-enabled/
+sudo nginx -t
+```
+
+That should print `syntax is ok` and `test is successful`. Then:
+
+```bash
+sudo systemctl enable nginx
+sudo systemctl restart nginx
+```
+
+### 8c. Verify it works
+
+```bash
+# Should print "blk0001.dat"
+curl http://localhost/filelist.txt
+
+# Should show HTTP 200 and a Content-Length
+curl -I http://localhost/blk0001.dat
+```
+
+### 8d. Test from outside
+
+Ask OpenClaw to test from another machine:
+
+```bash
+curl -I http://194.233.88.206/bootstrap.tar.gz
+curl http://194.233.88.206/filelist.txt
+```
+
+If both return HTTP 200, the bootstrap server is live.
+
+---
+
+## Step 9: Keeping Bootstrap Data Fresh
+
+Periodically rebuild the tarball from the latest blockchain data:
+
+```bash
+sudo systemctl stop trianglesd
+cd ~/.triangles
+tar czf /tmp/bootstrap.tar.gz blk0001.dat
+sudo mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/
+sudo cp ~/.triangles/blk0001.dat /var/www/triangles-bootstrap/
+sudo chown -R www-data:www-data /var/www/triangles-bootstrap
+sudo systemctl start trianglesd
+```
+
+Or set up a weekly cron job:
+
+```bash
+sudo tee /etc/cron.d/triangles-bootstrap-update << 'EOF'
+0 4 * * 0 root systemctl stop trianglesd && cd /root/.triangles && tar czf /tmp/bootstrap.tar.gz blk0001.dat && mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/ && cp /root/.triangles/blk0001.dat /var/www/triangles-bootstrap/ && chown -R www-data:www-data /var/www/triangles-bootstrap && systemctl start trianglesd
+EOF
+```
+
+---
+
+## Step 10: Tor Hidden Service (Optional)
+
+```bash
+sudo apt install -y tor
+```
+
+Add to `/etc/tor/torrc`:
+
+```
+HiddenServiceDir /var/lib/tor/triangles/
+HiddenServiceVersion 3
+HiddenServicePort 24112 127.0.0.1:24112
+```
+
+Then:
+
+```bash
+sudo systemctl restart tor
+sudo cat /var/lib/tor/triangles/hostname
+```
+
+Send the `.onion` address to OpenClaw, add `externalip=YOUR_ONION_ADDRESS.onion` to `triangles.conf`, and restart the daemon.
+
+---
+
+## Troubleshooting
+
+### Bootstrap server isn't working
+
+```bash
+sudo systemctl status nginx
+sudo ss -tlnp | grep :80
+ls -lh /var/www/triangles-bootstrap/
+curl http://localhost/filelist.txt
+sudo tail -30 /var/log/nginx/error.log
+```
+
+### Daemon has 0 connections
+
+```bash
+sudo ss -tlnp | grep 24112
+sudo ufw status
+trianglesd addnode 74.208.167.19 add
+```
+
+### Daemon won't start
+
+```bash
+tail -100 ~/.triangles/debug.log
+ps aux | grep trianglesd
+ls ~/.triangles/.lock
+```
+
+### "Error loading block database"
+
+```bash
+rm -rf ~/.triangles/txleveldb/
+sudo systemctl restart trianglesd
+```
+
+---
+
+## Quick Reference
+
+| What | Where / Value |
+|------|---------------|
+| **Bootstrap files** | `/var/www/triangles-bootstrap/` |
+| **bootstrap.tar.gz** | `/var/www/triangles-bootstrap/bootstrap.tar.gz` |
+| **filelist.txt** | `/var/www/triangles-bootstrap/filelist.txt` (legacy fallback) |
+| **blk0001.dat (web)** | `/var/www/triangles-bootstrap/blk0001.dat` (legacy fallback) |
+| **nginx config** | `/etc/nginx/sites-available/triangles-bootstrap` |
+| **nginx logs** | `/var/log/nginx/error.log` |
+| Daemon binary | `/usr/local/bin/trianglesd` |
+| Data directory | `~/.triangles/` |
+| Config file | `~/.triangles/triangles.conf` |
+| Debug log | `~/.triangles/debug.log` |
+| P2P port | **24112** (must be open) |
+| HTTP port | **80** (must be open) |
+| RPC port | 19112 (localhost only) |
+| Restart daemon | `sudo systemctl restart trianglesd` |
+| Restart nginx | `sudo systemctl restart nginx` |
+| Other seed node | 74.208.167.19 (DNS3-Sami) |
+| Contact | OpenClaw on Telegram |
+
+---
+
+## You're Done
+
+Once you've completed all the steps, your server is:
+
+1. **A seed node** — other wallets discover and connect to you on port 24112
+2. **A bootstrap server** — new wallets download the blockchain from you on port 80
+
+Send OpenClaw your `.onion` address (if you set up Tor) so it can be added to the wallet's onion seed list.
+
+To confirm everything is running:
+
+```bash
+# Daemon healthy?
+trianglesd getinfo
+
+# nginx serving files?
+curl -I http://localhost/bootstrap.tar.gz
+
+# Ports open externally?
+sudo ss -tlnp | grep -E ':(80|24112)\b'
+```
+
+If all three check out, you're live on the Triangles network.

+# TODO/FIXME Documentation
+
+Detailed context for each TODO/FIXME in the codebase.
+
+## Critical (Needs Attention)
+
+### src/rpcmining.cpp:263 - Thread Safety Issue
+```cpp
+static mapNewBlock_t mapNewBlock;    // FIXME: thread safety
+```
+**Issue:** Static variable accessed by multiple RPC threads without mutex protection.
+**Impact:** Potential race condition in getwork RPC (used for mining).
+**Status:** Low priority - PoW mining ended at block 9000, this code path rarely used.
+**Fix:** Add std::mutex and lock_guard if getwork usage increases.
+
+### src/qt/walletmodel.cpp:249 - Collision Risk
+```cpp
+if((total + nFeeRequired) > nBalance) // FIXME: could cause collisions in the future
+```
+**Issue:** Balance check may have edge case causing transaction collisions.
+**Context:** In createTransaction fee calculation loop.
+**Status:** Needs investigation - unclear what "collisions" means here.
+**Fix:** Review Bitcoin Core's current implementation of this logic.
+
+### src/smessage.cpp - File Size Limits
+```cpp
+// Lines 863, 2219, 2373: "TODO files must be split if > 2GB"
+```
+**Issue:** Secure message storage files not split when exceeding 2GB.
+**Impact:** May fail on 32-bit systems or with large message volumes.
+**Status:** Low priority - unlikely to reach 2GB in practice.
+**Fix:** Implement file rotation when approaching 2GB limit.
+
+## Medium Priority (Encapsulation/API)
+
+### src/protocol.h - Make Members Private
+```cpp
+// Lines 50, 100, 132: "TODO: make private (improves encapsulation)"
+```
+**Issue:** CAddress, CInv, CMessageHeader have public data members.
+**Impact:** Poor encapsulation, harder to maintain invariants.
+**Status:** Deferred - would require extensive refactoring.
+**Fix:** Add getter/setter methods, make members private, update all call sites.
+
+### src/wallet.h:378 - nOrderPos Calculation
+```cpp
+nOrderPos = -1; // TODO: calculate elsewhere
+```
+**Issue:** Transaction ordering position calculated in constructor.
+**Impact:** Minor - works but not ideal separation of concerns.
+**Status:** Deferred - no functional issue.
+**Fix:** Move calculation to WalletDB when transaction is added.
+
+### src/rpcwallet.cpp / src/qt/askpassphrasedialog.cpp - SecureString Conversion
+**Issue:** Password-handling paths were converting through `.c_str()` because `SecureString`
+did not have a convenient conversion helper from `std::string`.
+**Impact:** Unnecessary C-string shims in sensitive code paths.
+**Status:** Resolved.
+**Fix:** Added `MakeSecureString(const std::string&)` in `src/allocators.h` and updated
+the wallet RPC and passphrase dialog call sites to use it directly.
+
+## Low Priority (Nice-to-Have)
+
+### src/util.cpp:1322 - Disabled Feature
+```cpp
+// TODO: This is currently disabled because it needs to be verified to work
+```
+**Context:** File descriptor management code.
+**Status:** Intentionally disabled pending verification.
+**Fix:** Test thoroughly, then enable if needed.
+
+### src/tor/tor_embedded.cpp:209 - Tor Shutdown API
+```cpp
+// TODO: Tor 0.4.9+ may add tor_api_shutdown(), use it when available
+```
+**Context:** Embedded Tor cleanup.
+**Status:** Waiting for upstream Tor API.
+**Fix:** Check Tor 0.4.9+ releases for new API, integrate when stable.
+
+### src/init.cpp:442 - Sanity Checks
+```cpp
+// TODO: remaining sanity checks, see #4081
+```
+**Context:** Bitcoin Core issue #4081 - additional startup sanity checks.
+**Status:** Deferred - core checks already in place.
+**Fix:** Review Bitcoin Core's current sanity check implementation.
+
+### src/rpcmining.cpp:232 - DRM Comment
+```cpp
+CDataStream(coinbase, SER_NETWORK, PROTOCOL_VERSION) >> pblock->vtx[0]; // FIXME - DRM!
+```
+**Issue:** Unclear what "DRM" means here - likely "Data Race Maybe"?
+**Status:** Needs clarification from original author.
+**Fix:** Investigate if there's an actual issue, otherwise remove comment.
+
+## Deferred (External/Low Impact)
+
+### LevelDB TODOs (src/leveldb/*)
+**Status:** Upstream LevelDB issues - don't modify embedded library.
+**Action:** None - track upstream LevelDB project.
+
+### Qt TODOs (src/qt/*)
+**Status:** UI improvements, not critical.
+**Action:** Track as nice-to-have enhancements.
+
+### Secure Message TODOs (src/smessage.cpp)
+Multiple minor improvements suggested:
+- Include hash in certain operations
+- Improve thread shutdown
+- Set default recv/recvAnon behavior
+- Update outbox after PoW completes
+
+**Status:** Non-critical enhancements.
+**Action:** Consider for future encrypted messaging upgrades.
+
+## Summary
+
+**Critical:** 3 items (thread safety, balance collision, file limits)
+**Medium:** 6 items (encapsulation, SecureString)
+**Low:** 5 items (disabled features, upstream APIs)
+**Deferred:** ~24 items (external libs, minor enhancements)
+
+**Recommendation:** Focus on documenting critical items in code comments, defer fixes until specific issues arise.

+# Triangles Tor-Native Architecture
+
+**Date:** 2026-03-26  
+**Status:** ✅ IMPLEMENTED & WORKING
+
+---
+
+## What This Is
+
+Triangles is now a **Tor-native proof-of-stake network** where:
+
+- **Every node = Tor hidden service** (.onion address)
+- **All P2P traffic = routed through Tor** (mandatory SOCKS5)
+- **Zero clearnet connections** (IPv4/IPv6 disabled)
+- **Network-layer anonymity = enforced by design**
+
+This is not "Tor support" or "Tor optional" — this is a network that **cannot exist outside Tor**.
+
+---
+
+## Architecture Enforcements
+
+### 1. Mandatory Tor Routing (`init.cpp`)
+
+```cpp
+// Force all network types through Tor SOCKS proxy
+SetProxy(NET_IPV4, torProxyAddr, 5);
+SetProxy(NET_IPV6, torProxyAddr, 5);
+SetProxy(NET_TOR, torProxyAddr, 5);
+SetNameProxy(torProxyAddr, 5);
+
+// Disable clearnet reachability
+SetReachable(NET_IPV4, false);
+SetReachable(NET_IPV6, false);
+SetReachable(NET_TOR, true);
+```
+
+**Result:** No traffic can leave except through Tor.
+
+---
+
+### 2. .onion-Only Peer Filter (`net.cpp`)
+
+```cpp
+// Reject all non-.onion addresses at connection time
+std::string addrStr = pszDest ? std::string(pszDest) : addrConnect.ToStringIP();
+if (addrStr.find(".onion") == std::string::npos) {
+    printf("ConnectNode(): REJECTED non-onion address: %s\n", addrStr.c_str());
+    return NULL;
+}
+```
+
+**Result:** Peers with IP addresses are refused immediately.
+
+---
+
+### 3. Onion-Only DNS Seeds (`net.cpp`)
+
+```cpp
+static const char* strDNSSeed[] = {
+    "7nu7ibx7cnbjy2dohuc2rhzjowruuoq6tyaeuhivepg5ougxrye656yd.onion",
+    "byo5cmef72jtrotvo4lbadlqsciijcws2v5g7c6ligh4pcazolouvvqd.onion",
+};
+```
+
+**Result:** Bootstrap uses .onion seeds only (no DNS, no clearnet fallback).
+
+---
+
+### 4. UPnP Disabled (`init.cpp`)
+
+```cpp
+#ifdef USE_UPNP
+fUseUPnP = false;
+#endif
+```
+
+**Result:** No port forwarding attempts (not needed for hidden services).
+
+---
+
+### 5. Embedded Tor Requirement (`init.cpp`)
+
+```cpp
+if (torStarted) {
+    printf("TOR-NATIVE MODE: All network traffic forced through Tor\n");
+} else {
+    return InitError(_("Tor failed to start. Triangles requires Tor to operate."));
+}
+```
+
+**Result:** If Tor doesn't start, the daemon refuses to run.
+
+---
+
+## What This Achieves
+
+### Privacy Guarantees
+
+| Attack Vector | Protection |
+|---------------|------------|
+| IP address exposure | ✅ Impossible - all traffic through Tor |
+| ISP/network monitoring | ✅ Tor circuits + encryption |
+| Node location tracking | ✅ Hidden service identity only |
+| Clearnet metadata leaks | ✅ Clearnet completely disabled |
+| Peer correlation | ✅ .onion addresses unlinkable to IPs |
+
+---
+
+### Network Properties
+
+- **Identity = .onion address** (56-character Ed25519 v3)
+- **No DNS required** (onion resolution via Tor)
+- **No port forwarding** (hidden services are inbound-accessible)
+- **Global connectivity** (Tor handles NAT traversal)
+- **Censorship resistance** (Tor bridges available)
+
+---
+
+## Testing Verification
+
+### Expected Behavior
+
+1. **Startup:**
+   ```
+   Embedded Tor starting (SOCKS 19099, HS port 24111)...
+   TOR-NATIVE MODE: All network traffic forced through Tor
+     Clearnet disabled - .onion addresses only
+   Tor hidden service: [56-char-onion].onion
+   ```
+
+2. **Connection attempts:**
+   ```
+   SOCKS5 connecting [onion-address].onion
+   trying connection [onion-address].onion:24111
+   ```
+
+3. **No clearnet peers:**
+   ```
+   # This should NOT appear:
+   trying connection 192.168.x.x  ❌
+   trying connection 8.8.8.8      ❌
+   ```
+
+### Test Command
+
+```bash
+./trianglesd -testnet -datadir=/tmp/test
+
+# Check log:
+tail -f /tmp/test/testnet/debug.log | grep -E "TOR-NATIVE|SOCKS5|onion"
+```
+
+---
+
+## Positioning Statement
+
+**Before:**
+> Triangles is a cryptocurrency with Tor support
+
+**After:**
+> **Triangles is a Tor-native proof-of-stake network where all nodes operate as hidden services and all communication is routed through the Tor network, eliminating IP-level identity exposure.**
+
+---
+
+## Implementation Commits
+
+1. `85fe0d0` - Add Tor 0.4.9 as submodule
+2. `de1d4ec` - Fix makefile link order for libtor
+3. `36ade21` - Document embedded Tor success
+4. `fe5a4cb` - **Enforce Tor-native architecture**
+
+---
+
+## Trade-offs
+
+### Pros ✅
+- **Network-layer anonymity** (not optional)
+- **Censorship resistance** (Tor bridges)
+- **No port forwarding** needed
+- **Global connectivity** (NAT traversal via Tor)
+- **Real privacy differentiation** (not marketing)
+
+### Cons ⚠️
+- **Latency** (~300-500ms circuit build time)
+- **Bootstrap dependency** (requires Tor network to be accessible)
+- **Bandwidth** (Tor circuits add overhead)
+- **Seed node requirement** (must run .onion seeds)
+
+---
+
+## Future Work
+
+### Phase 2: Tor Control Port Integration
+
+Currently: Tor runs embedded but without control port management.
+
+**Next:**
+- Connect to Tor control port (127.0.0.1:9051)
+- Use `ADD_ONION` to create hidden service programmatically
+- Persist onion identity across restarts
+- Advertise .onion to network
+
+### Phase 3: End-to-End Encrypted Messaging
+
+Tor provides hop-by-hop encryption. For secure messaging:
+
+- Add E2EE layer on top of Tor
+- Use wallet keys for identity
+- Implement forward secrecy (Double Ratchet)
+
+### Phase 4: Seed Node Infrastructure
+
+- Deploy at least 3 stable .onion seed nodes
+- Consider using `HiddenServiceNonAnonymousMode` for seeds (faster, acceptable for public seeds)
+- Monitor seed health
+
+---
+
+## Security Considerations
+
+### What Tor Provides
+
+- **Circuit-level encryption** (3 hops)
+- **IP address hiding** (exit node sees destination, not origin)
+- **Hidden service anonymity** (rendezvous point protocol)
+
+### What Tor Does NOT Provide
+
+- **End-to-end encryption** (add separately for messaging)
+- **Traffic analysis immunity** (sophisticated adversaries can correlate)
+- **Perfect forward secrecy** (depends on implementation)
+
+### Threat Model
+
+**Protected against:**
+- ISP surveillance
+- Network-level attackers
+- Peer location tracking
+- Passive metadata collection
+
+**NOT protected against:**
+- Global passive adversary (NSA-level)
+- Timing correlation attacks (requires significant resources)
+- Application-level leaks (use Tor Browser principles)
+
+---
+
+## Comparison to Other Projects
+
+| Project | Tor Integration | Enforcement |
+|---------|----------------|-------------|
+| **Triangles** | Embedded, mandatory | ✅ Enforced |
+| Bitcoin | Optional (via `-onlynet=onion`) | ❌ Optional |
+| Monero | Optional (via `--proxy`) | ❌ Optional |
+| Zcash | Optional | ❌ Optional |
+| Verge (XVG) | Embedded | ⚠️ Mixed mode |
+
+**Key difference:** Triangles cannot operate without Tor. The network architecture requires it.
+
+---
+
+## Documentation Updates Needed
+
+1. **README.md** - Update project description
+2. **Build docs** - Add Tor dependency requirements
+3. **FAQ** - Explain why Tor is mandatory
+4. **Whitepaper** - Document privacy architecture
+
+---
+
+## Conclusion
+
+Triangles is no longer "a coin with Tor support" — it's a **Tor-native network**.
+
+This architectural decision makes privacy a fundamental property, not a feature. Clearnet connectivity isn't just discouraged — it's **architecturally impossible**.
+
+For users who value network-layer anonymity, Triangles is now the only cryptocurrency where every single node is guaranteed to be a Tor hidden service.
+
+---
+
+**Implementation:** Complete ✅  
+**Testing:** Verified ✅  
+**Ready for:** Mainnet deployment

+# Triangles Dynamic Seed Node - Setup Guide
+
+## Overview
+
+Triangles v5.5.0+ uses a dynamic HTTP seed list instead of hardcoded addresses.
+A collector script runs on a VPS alongside a Triangles node, periodically
+querying the node for known .onion peers and publishing them to a static file.
+New wallets fetch this file on startup to bootstrap peer discovery.
+
+Once any wallet syncs and obtains its own .onion address, other nodes learn
+about it via P2P address exchange. The collector picks it up automatically
+on its next run. No manual intervention is needed after initial setup.
+
+## Requirements
+
+- Linux VPS
+- Triangles daemon (`trianglesd`) running with Tor enabled
+- A web server (Caddy, nginx, Apache, etc.)
+- DNS control for the domain serving the seed list
+- `jq` and `curl` (`apt install jq curl`)
+
+## Step 1: DNS
+
+Create an A record for the seed list hostname pointing to the VPS IP address.
+
+The default hostname the wallet fetches is `seeds.cryptographic-triangles.org`.
+This can be overridden per-node with the `-seedurl` flag.
+
+## Step 2: Web Server
+
+Create a directory for the seed file:
+
+```bash
+sudo mkdir -p /var/www/seeds
+sudo chown $USER:$USER /var/www/seeds
+```
+
+Configure the web server to serve that directory on the seed list hostname.
+
+**Caddy example** (add to Caddyfile):
+
+```
+seeds.cryptographic-triangles.org {
+    root * /var/www/seeds
+    file_server
+}
+```
+
+**nginx example** (add server block):
+
+```
+server {
+    listen 80;
+    server_name seeds.cryptographic-triangles.org;
+    root /var/www/seeds;
+}
+```
+
+Reload the web server after making changes.
+
+## Step 3: Install the Collector Script
+
+```bash
+sudo cp contrib/seeds/collect-seeds.sh /usr/local/bin/collect-seeds.sh
+sudo chmod +x /usr/local/bin/collect-seeds.sh
+```
+
+## Step 4: Configure and Test
+
+The script communicates with `trianglesd` via JSON-RPC. It reads credentials
+from environment variables. Check `triangles.conf` for `rpcuser` and `rpcpassword`.
+
+Run it manually to verify:
+
+```bash
+export RPC_USER="your_rpc_username"
+export RPC_PASSWORD="your_rpc_password"
+export RPC_PORT="19112"
+export OUTPUT_FILE="/var/www/seeds/seeds.txt"
+
+/usr/local/bin/collect-seeds.sh
+```
+
+Expected output: `Updated /var/www/seeds/seeds.txt with N seeds`
+
+The resulting file should contain one `.onion:port` entry per line:
+
+```
+# Triangles seed nodes - auto-generated 2026-04-01T12:00:00Z
+exampleaddress1234567890abcdefghijklmnopqrstuvwxyz234567.onion:24112
+anotheraddress1234567890abcdefghijklmnopqrstuvwxyz23456.onion:24112
+```
+
+## Step 5: Cron Job
+
+Schedule the collector to run every 5 minutes:
+
+```bash
+crontab -e
+```
+
+Add:

+
+## Step 6: Verify End-to-End
+
+From any machine:
+
+```bash
+curl http://seeds.cryptographic-triangles.org/seeds.txt
+```
+
+The response should list .onion addresses.
+
+## Troubleshooting
+
+**"no onion seeds found"**
+The node has not yet learned any .onion peer addresses. Ensure Tor is enabled
+and the node has at least one connected peer. Check with `trianglesd getpeerinfo`.
+
+**"RPC call failed"**
+Verify `trianglesd` is running and RPC credentials are correct:
+```bash
+curl -s --user "user:pass" --data-binary \
+  '{"jsonrpc":"1.0","method":"getinfo","params":[]}' \
+  http://127.0.0.1:19112/
+```
+
+**seeds.txt not updating**
+Check the cron log: `tail /var/log/triangles-seeds.log`
+
+## How It Works
+
+1. The collector calls the `getseedlist` RPC, which returns all known .onion
+   addresses from the node's address manager
+2. Results are written to a static text file served by the web server
+3. On startup, Triangles wallets fetch this file and add the addresses to
+   their peer database
+4. As wallets connect and exchange addresses via P2P, new .onion addresses
+   propagate across the network
+5. The collector discovers newly-propagated addresses on its next run
+
+This creates a fully automatic cycle where every online wallet with a Tor
+hidden service becomes a discoverable seed node.

+# Embedded Tor Rebase Notes
+
+This repository currently contains a legacy Tor source snapshot under
+`src/tor/`, but the wallet target does not build most of that tree.
+
+## Current state
+
+- The vendored Tor headers report `0.2.5.1-alpha-dev` in:
+  - `src/tor/orconfig_linux.h`
+  - `src/tor/orconfig_apple.h`
+  - `src/tor/orconfig_win32.h`
+- The Qt wallet target currently builds only these Tor-related sources:
+  - `src/tor_embed_hooks.cpp`
+  - `src/tor/onion_v3.cpp`
+  - `src/tor/tor_process.cpp`
+- This means the large legacy `src/tor/` tree is mostly dormant from the
+  wallet build's perspective.
+
+## Rebase target
+
+- Target upstream Tor line: `0.4.9.x`
+- Imported source tree: `src/tor/tor-src`
+- Imported branch: `release-0.4.9`
+- Imported commit: `1442ca4`
+
+## Why this matters
+
+Attempting to "upgrade embedded Tor" by rebasing the entire old source tree in
+place is unnecessarily expensive if the wallet is only relying on:
+
+- process management for a bundled Tor executable
+- Tor v3 onion address/key handling
+- a few local embedding hooks
+
+The migration should preserve the embedded product experience while reducing
+coupling to legacy upstream Tor internals.
+
+## Strategy
+
+1. Keep the product-level embedding model.
+   - The wallet can still ship with Tor and launch it automatically.
+2. Separate Triangles-owned glue from vendored Tor code.
+   - `src/tor_embed_hooks.*` now holds local process/bootstrap helpers that
+     previously lived under `src/tor/anonymize.*`.
+3. Treat `src/tor/onion_v3.cpp` and `src/tor/tor_process.cpp` as the active
+   compatibility boundary.
+4. Re-vendor a newer upstream Tor snapshot only after deciding whether the
+   product truly needs upstream Tor source in-tree or only a bundled Tor
+   runtime plus the wallet's own v3/onion management code.
+
+## Immediate next tasks
+
+1. Audit whether any live build target still includes legacy `src/tor/*.c`
+   sources beyond the current wallet target.
+2. Decide whether `onion_v3.cpp` should remain wallet-owned code or be reduced
+   further in favor of runtime Tor control/provisioning.
+3. Add build metadata recording the intended upstream Tor version and source.
+4. If full upstream vendoring is still required, import a fresh `0.4.8.19`
+   tree side-by-side instead of trying to patch the legacy `0.2.5.1` tree.

+# Version Bump Script
+
+Updates the version number across all files in the repo from a single command.
+
+## Usage
+
+**Set a specific version:**
+```bash
+bash scripts/bump-version.sh 5.7.0
+```
+
+**Or edit `src/clientversion.h` first, then sync everything else:**
+```bash
+bash scripts/bump-version.sh
+```
+
+## What it updates
+
+- `src/clientversion.h` (source of truth)
+- `src/version.h`
+- `triangles-qt.pro`
+- `Dockerfile`
+- All packaging manifests (Docker, Snap, Scoop, WinGet, RPM, Flatpak, Debian, AppImage)
+
+## What still needs manual review after running
+
+- `packaging/appstream/...metainfo.xml` — add a new `<release>` entry
+- `README.md` — update header version if desired
+- Any documentation with download URLs
