Triangles is a privacy-focused cryptocurrency featuring Proof-of-Stake consensus, Tor v3 onion routing, and built-in encrypted messaging. Originally launched in July 2014, the chain was revived in March 2026 after being frozen since December 2022.

Key Features

Proof-of-Stake - Energy-efficient block production with 33% annual staking rewards (coin-age based)
Hash9 Algorithm - Unique 13-step hash cascade (Fugue, Hamsi, Groestl, Blake, BMW, Skein, Keccak, Shavite, JH, Luffa, Cubehash, Echo, SIMD)
Encrypted Messaging - Send and receive encrypted messages directly through the wallet
Tor v3 Integration - Connect and transact over the Tor network with v3 onion hidden services
120-second Block Time - Fast confirmations with 2-minute target spacing

Network Status

The Triangles network is live with seed nodes operating on both clearnet and Tor:

Clearnet Seeds:

194.233.88.206:24112
74.208.167.19:24112

Tor v3 Seeds:

gxvrhv3qitnc6kobrhsrse46bmcfitnybapor3or3oczzuxn6hfzxyid.onion:24112
futmtrvh6j34t7s6yjdxfia6iwuyfzwh4k5eqfof5kfhoqk3xmi3qoqd.onion:24112

DNS Seeds:

seed2.cryptographic-triangles.org

Building from Source

Linux (Ubuntu 24.04 / Debian 12+)

Install dependencies:

sudo apt-get install -y build-essential libboost-all-dev libssl-dev \
    libdb5.3++-dev libevent-dev zlib1g-dev libminiupnpc-dev

Build the daemon:

cd src/leveldb && make libleveldb.a libmemenv.a && cd ..
make -j$(nproc) -f makefile.unix USE_UPNP=0
strip trianglesd

Linux (AlmaLinux 9 / RHEL 9)

Install dependencies:

sudo dnf install -y gcc-c++ make boost-devel openssl-devel libevent-devel \
    zlib-devel miniupnpc-devel

BDB 5.3 C++ bindings must be built from source on RHEL-based systems (the libdb-devel package does not include C++ headers). Download BDB 5.3.28 from Oracle and build with --enable-cxx.

Then build as above.

Windows (MSYS2 MinGW64)

Open an MSYS2 MinGW64 shell and install:

pacman -S mingw-w64-x86_64-boost mingw-w64-x86_64-openssl \
    mingw-w64-x86_64-db mingw-w64-x86_64-miniupnpc \
    mingw-w64-x86_64-qt5-base mingw-w64-x86_64-qrencode

Build the Qt wallet:

qmake triangles-qt.pro
make -j$(nproc)

Running

First Run

mkdir -p ~/.triangles
cat > ~/.triangles/triangles.conf << 'EOF'
port=24112
rpcport=19112
rpcuser=trianglesrpc
rpcpassword=<generate-a-strong-password>
rpcallowip=127.0.0.1
staking=1
txindex=1
listen=1
server=1
daemon=1
addnode=194.233.88.206
addnode=74.208.167.19
externalip=<your-public-ip>
EOF

trianglesd

The node will connect to seed nodes and sync the blockchain automatically.

Existing Wallet Holders

If you have a wallet.dat from the original Triangles network:

Place your wallet.dat in ~/.triangles/ (Linux) or %APPDATA%\triangles\ (Windows)
Start the wallet - it will sync the blockchain and your balance will appear automatically
No migration or special action is needed - all keys and balances are preserved

Staking

To stake, your wallet must be:

Running with staking=1 in the config
Connected to at least one peer
Containing coins with sufficient coin-age (mature inputs)

Check staking status:

trianglesd getstakinginfo

Encrypted Messaging

Send and receive encrypted messages between wallet addresses:

# Enable messaging
trianglesd smsgenable

# Send a message
trianglesd smsgsend <your-address> <recipient-address> "Hello from Triangles!"

# Check inbox
trianglesd smsginbox all

# Send anonymous message
trianglesd smsgsendanon <recipient-address> "Anonymous message"

Messages are encrypted end-to-end using AES and distributed through the peer network in time-bucketed batches.

Tor Support

To connect through Tor, install the Tor daemon and add to your config:

# triangles.conf
proxy=127.0.0.1:9050

To run your own hidden service, add to /etc/tor/torrc:

HiddenServiceDir /var/lib/tor/triangles/
HiddenServiceVersion 3
HiddenServicePort 24112 127.0.0.1:24112

Then set externalip=<your-onion-address> in triangles.conf.
