Run a Triangles (TRI) cryptocurrency node on Raspberry Pi 4/5 or any ARM64 server. Includes Tor integration, systemd service, and optional blockchain bootstrap.

Quick Start

One-liner install

curl -sSL https://raw.githubusercontent.com/SamiAhmed7777/tri-pi/main/bootstrap.sh | sudo bash

Downloads the latest release, installs dependencies, creates a systemd service, and offers blockchain bootstrap. Ready in ~60 seconds.

Manual install

# Download latest release
wget https://github.com/SamiAhmed7777/tri-pi/releases/latest/download/tri-pi-$(curl -fsSL https://api.github.com/repos/SamiAhmed7777/triangles_v5/releases/latest | jq -r .tag_name | sed 's/^v//')-arm64.tar.gz
tar xzf tri-pi-*.tar.gz

# Install
sudo ./install.sh

What's Included

File	Purpose
`bin/trianglesd`	Native ARM64 binary (stripped, ~5MB)
`install.sh`	Interactive installer with bootstrap option
`bootstrap.sh`	One-liner installer (fetches latest release)
`BOOTSTRAP.md`	Blockchain bootstrap guide
`docs/BUILD.md`	Build-from-source instructions

After Installation

# Start the node
sudo systemctl start triangles

# Check status
trianglesd -datadir=/root/.triangles getinfo

# Watch sync progress
watch -n5 'trianglesd -datadir=/root/.triangles getinfo | grep blocks'

# View logs
journalctl -u triangles -f
tail -f /root/.triangles/debug.log

# View Tor onion address
cat /root/.triangles/onion/hostname

Common commands

trianglesd -datadir=/root/.triangles getblockcount      # Current block height
trianglesd -datadir=/root/.triangles getpeerinfo         # Connected peers
trianglesd -datadir=/root/.triangles getstakinginfo      # Staking status
trianglesd -datadir=/root/.triangles getnewaddress       # New address
trianglesd -datadir=/root/.triangles getbalance           # Wallet balance

Tip: Create an alias to save typing:

echo 'alias tri="trianglesd -datadir=/root/.triangles"' >> ~/.bashrc && source ~/.bashrc
tri getinfo

System Requirements

	Minimum	Recommended
Platform	Raspberry Pi 4 (64-bit)	Raspberry Pi 5 or ARM64 VPS
OS	Ubuntu 24.04, Pi OS 64-bit	Ubuntu 24.04 LTS
RAM	2 GB	4 GB
Storage	5 GB free	10 GB free
Network	Internet (Tor supported)	Wired ethernet

Blockchain Bootstrap

Syncing from genesis takes days/weeks on a Pi. The installer offers a pre-synced blockchain download (~1.3 GB) that gets you running in minutes.

If bootstrap fails during install (server unreachable from your network), you can manually transfer:

# From a machine that can reach the bootstrap server:
curl -O https://bootstrap.cryptographic-triangles.org/tri-bootstrap.tar.gz
scp tri-bootstrap.tar.gz pi@your-pi:/tmp/

# On the Pi:
sudo systemctl stop triangles
cd /root/.triangles
tar xzf /tmp/tri-bootstrap.tar.gz
sudo systemctl start triangles

Tor Integration

trianglesd manages Tor automatically:

Starts Tor as a child process on port 19099
Generates a .onion hidden service address
Connects to onion seed nodes
No manual Tor configuration needed

Do NOT set onion= or tor= in the config — the daemon handles everything.

Automated Builds

New releases are built automatically via GitHub Actions when upstream triangles_v5 publishes a release. The CI uses QEMU ARM64 emulation on GitHub-hosted runners.

Manual trigger: Actions → "Build TRI-PI ARM64" → "Run workflow". You can leave the version blank to build the latest upstream release, or provide a specific upstream tag such as v5.8.1.

Network

Port	Protocol	Purpose
24112	TCP	P2P network
19199	TCP	RPC (localhost only)
19099	TCP	Tor SOCKS (internal)
