Official client daemon for Kryvora Network nodes.

Overview

Kryvora is a decentralized physical infrastructure network designed for distributed verification and worker coordination. The kryvora-node daemon connects worker hardware to the Kryvora Hub, executes telemetry probes, verifies peer state, and reports proof of availability.

Node Licensing & Genesis Key Requirement

Operating a Kryvora verification node requires an active Genesis Node Key. The Genesis Node Key is an on-chain soulbound verification credential deployed on Arbitrum One:

• Contract: 0xBCf2cD12D1D37578fA7C69805fE77788e866BE1a
• Network: Arbitrum One (Chain ID: 42161)
• Portal: https://node.kryvora.network

Before launching the daemon, obtain your node bootstrap token by connecting your wallet at node.kryvora.network. Unauthenticated nodes without a valid bootstrap token will be rejected by the Coordination Hub (hub.kryvora.network:4188).

System Requirements

Hardware specs for running a standard verification worker:

• CPU: 2 cores minimum (x86_64 or arm64)
• Memory: 2 GB RAM minimum, 4 GB recommended
• Storage: 20 GB available SSD storage
• Network: Stable broadband connection with inbound port 4177 open for local telemetry probes

Quick Start

Option 1: Automated Script (Linux systemd)

Run the installation script to fetch the binary and register the systemd service:

curl -sSL https://raw.githubusercontent.com/kryvora-network/kryvora-node/main/install.sh | bash

The script will prompt for your Genesis Node Key bootstrap token and register the systemd service.

Check service status:

sudo systemctl status kryvora-node

Option 2: Docker Compose

1. Clone the repository:

git clone https://github.com/kryvora-network/kryvora-node.git
cd kryvora-node

2. Copy the configuration template and set your token:

cp config.example.yaml config.yaml
# Edit config.yaml and insert your bootstrap_token under auth:
# Or set KRYVORA_BOOTSTRAP_TOKEN in your environment

3. Start the node container:

KRYVORA_BOOTSTRAP_TOKEN="your_token_here" docker compose up -d

4. Verify logs:

docker compose logs -f kryvora-node

Option 3: Build from Source

Requirements: Go 1.22 or higher.

git clone https://github.com/kryvora-network/kryvora-node.git
cd kryvora-node
make build
./bin/kryvora-node --config config.yaml --token "your_token_here"

Configuration

Configuration is loaded from config.yaml or set via environment variables.

Key	Type	Default	Description
node.id	string	auto-generated	Unique identifier for worker node
node.listen_addr	string	0.0.0.0:4177	Local address for telemetry and metrics
node.data_dir	string	/var/lib/kryvora	Local state and task database directory
auth.bootstrap_token	string	""	Mandatory: Genesis Node Key activation token
hub.endpoint	string	https://hub.kryvora.network:4188	Upstream coordination hub address
hub.heartbeat_interval	int	30	Interval in seconds between hub pings
telemetry.enabled	bool	true	Expose Prometheus metrics on /metrics

Local Endpoints

When running, the daemon exposes the following endpoints on port 4177:

• GET /health: JSON response indicating daemon lifecycle status
• GET /status: Peer connectivity, current block height, and sync state
• GET /metrics: Prometheus-compatible telemetry counters

Example query:

curl -s http://127.0.0.1:4177/status
