QoreChain Light Node

v3.1.1 — aligned with qorechain-core@v3.0.2. Adds a PQC regression test suite (keygen, sign, verify, and tamper-detection) that guards the v3.0.2 signature-verification fix, and runs it in CI. No runtime behaviour change from v3.1.0.

Light node client for the QoreChain network. Provides two editions:

• SX (Server eXperience) — headless daemon with CLI for server deployments
• UX (User eXperience) — embedded web dashboard with CLI for desktop use

Features

• Header verification via skipping verification light client
• Delegated staking with multi-validator split
• Auto-compound rewards with configurable intervals
• Reputation-aware validator rebalancing
• Real-time network telemetry (validators, consensus, bridge, tokenomics)
• On-chain registration with heartbeat liveness proofs
• 3% block reward eligibility for active light nodes
• Post-quantum cryptography support (Dilithium-5)
• Interactive onboarding wizard that runs a PQC self-test, accepts the chain RPC endpoint, and imports or generates a Dilithium-5 validator key
• Local-only mode so the node can prove its PQC stack works even before the chain itself is deployed
• Live PQC self-test — lightnode-sx selftest runs keygen → sign → verify → tamper-detection in under a second

Quick Start

First-time setup

# 1. Build (or pull the Docker image)
CGO_ENABLED=1 go build -o build/lightnode-sx ./cmd/lightnode-sx/

# 2. Run the onboarding wizard — PQC self-test + endpoint + key prompts
build/lightnode-sx onboard

# 3. Start the daemon
build/lightnode-sx start

The wizard asks for:

• Chain RPC endpoint — paste the URL (e.g. https://rpc.qorechain.io:26657), or leave blank to run in local-only mode while the chain itself is still being deployed.
• Private key — paste a hex-encoded Dilithium-5 key, or type g to generate a fresh one on this node.

If you leave the endpoint blank the daemon will start in local-only mode — the PQC stack is fully exercised and the web dashboard shows a banner explaining the state. Re-run onboard once the chain is live to point at a real RPC.

Build from Source

# SX edition (server daemon)
CGO_ENABLED=1 go build -o build/lightnode-sx ./cmd/lightnode-sx/

# UX edition (dashboard + daemon)
CGO_ENABLED=1 go build -o build/lightnode-ux ./cmd/lightnode-ux/

Docker

docker compose up lightnode-sx    # server edition
docker compose up lightnode-ux    # dashboard edition (port 8080)

Verify the PQC stack any time

lightnode-sx selftest

Runs 5 checks: keygen, sign, verify-valid, reject-tampered-sig, reject-tampered-msg.

Configuration
