# Multi-Cloud Image Build Setup
This document explains how to set up the CI/CD pipeline for building Lux Network node images on AWS, GCP, and Azure.
## Overview
The workflows automatically build machine images when:
- A new version tag is pushed (`v*`)
- A GitHub release is published
- Manually triggered via workflow dispatch
## Required GitHub Secrets
### AWS Secrets
| Secret | Description | How to Obtain |
|--------|-------------|---------------|
| `AWS_AMI_ROLE_ARN` | IAM role ARN for OIDC authentication | See AWS Setup below |
### GCP Secrets
| Secret | Description | How to Obtain |
|--------|-------------|---------------|
| `GCP_PROJECT_ID` | Google Cloud project ID | GCP Console |
| `GCP_WORKLOAD_IDENTITY_PROVIDER` | Workload Identity Federation provider | See GCP Setup below |
| `GCP_SERVICE_ACCOUNT` | Service account email | See GCP Setup below |
### Azure Secrets
| Secret | Description | How to Obtain |
|--------|-------------|---------------|
| `AZURE_CLIENT_ID` | Azure AD application ID | See Azure Setup below |
| `AZURE_CLIENT_SECRET` | Azure AD application secret | See Azure Setup below |
| `AZURE_TENANT_ID` | Azure AD tenant ID | Azure Portal |
| `AZURE_SUBSCRIPTION_ID` | Azure subscription ID | Azure Portal |
| `AZURE_RESOURCE_GROUP` | Resource group for images | Create in Azure |
---
## AWS Setup
### 1. Create OIDC Identity Provider
```bash
# Create the OIDC provider for GitHub Actions
aws iam create-open-id-connect-provider \
--url https://token.actions.githubusercontent.com \
--client-id-list sts.amazonaws.com \
--thumbprint-list 6938fd4d98bab03faadb97b34396831e3780aea1
```
### 2. Create IAM Role
```bash
# Create trust policy file
cat > trust-policy.json << 'EOF'
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Federated": "arn:aws:iam::YOUR_ACCOUNT_ID:oidc-provider/token.actions.githubusercontent.com"
},
"Action": "sts:AssumeRoleWithWebIdentity",
"Condition": {
"StringEquals": {
"token.actions.githubusercontent.com:aud": "sts.amazonaws.com"
},
"StringLike": {
"token.actions.githubusercontent.com:sub": "repo:luxfi/node:*"
}
}
}
]
}
EOF
# Create the role
aws iam create-role \
--role-name GitHubActionsLuxAMI \
--assume-role-policy-document file://trust-policy.json
```
### 3. Attach Permissions
```bash
# Create policy for Packer AMI building
cat > packer-policy.json << 'EOF'
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"ec2:AttachVolume",
"ec2:AuthorizeSecurityGroupIngress",
"ec2:CopyImage",
"ec2:CreateImage",
"ec2:CreateKeypair",
"ec2:CreateSecurityGroup",
"ec2:CreateSnapshot",
"ec2:CreateTags",
"ec2:CreateVolume",
"ec2:DeleteKeyPair",
"ec2:DeleteSecurityGroup",
"ec2:DeleteSnapshot",
"ec2:DeleteVolume",
"ec2:DeregisterImage",
"ec2:DescribeImageAttribute",
"ec2:DescribeImages",
"ec2:DescribeInstances",
"ec2:DescribeInstanceStatus",
"ec2:DescribeRegions",
"ec2:DescribeSecurityGroups",
"ec2:DescribeSnapshots",
"ec2:DescribeSubnets",
"ec2:DescribeTags",
"ec2:DescribeVolumes",
"ec2:DetachVolume",
"ec2:GetPasswordData",
"ec2:ModifyImageAttribute",
"ec2:ModifyInstanceAttribute",
"ec2:ModifySnapshotAttribute",
"ec2:RegisterImage",
"ec2:RunInstances",
"ec2:StopInstances",
"ec2:TerminateInstances"
],
"Resource": "*"
}
]
}
EOF
aws iam put-role-policy \
--role-name GitHubActionsLuxAMI \
--policy-name PackerAMIBuilder \
--policy-document file://packer-policy.json
```
### 4. Add Secret to GitHub
```bash
# Get the role ARN
aws iam get-role --role-name GitHubActionsLuxAMI --query 'Role.Arn' --output text
# Add to GitHub secrets:
# AWS_AMI_ROLE_ARN = arn:aws:iam::YOUR_ACCOUNT_ID:role/GitHubActionsLuxAMI
```
---
## GCP Setup
### 1. Create Service Account
```bash
PROJECT_ID="your-gcp-project"
# Create service account
gcloud iam service-accounts create github-packer \
--project=$PROJECT_ID \
--display-name="GitHub Actions Packer"
# Grant permissions
gcloud projects add-iam-policy-binding $PROJECT_ID \
--member="serviceAccount:github-packer@$PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/compute.instanceAdmin.v1"
gcloud projects add-iam-policy-binding $PROJECT_ID \
--member="serviceAccount:github-packer@$PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/compute.imageAdmin"
gcloud projects add-iam-policy-binding $PROJECT_ID \
--member="serviceAccount:github-packer@$PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/iam.serviceAccountUser"
```
### 2. Setup Workload Identity Federation
```bash
# Create workload identity pool
gcloud iam workload-identity-pools create github-pool \
--project=$PROJECT_ID \
--location="global" \
--display-name="GitHub Actions Pool"
# Create provider
gcloud iam workload-identity-pools providers create-oidc github-provider \
--project=$PROJECT_ID \
--location="global" \
--workload-identity-pool="github-pool" \
--display-name="GitHub Provider" \
--attribute-mapping="google.subject=assertion.sub,attribute.actor=assertion.actor,attribute.repository=assertion.repository" \
--issuer-uri="https://token.actions.githubusercontent.com"
# Allow GitHub to impersonate service account
gcloud iam service-accounts add-iam-policy-binding \
github-packer@$PROJECT_ID.iam.gserviceaccount.com \
--project=$PROJECT_ID \
--role="roles/iam.workloadIdentityUser" \
--member="principalSet://iam.googleapis.com/projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/github-pool/attribute.repository/luxfi/node"
```
### 3. Get Provider URL
```bash
# Get the provider resource name
gcloud iam workload-identity-pools providers describe github-provider \
--project=$PROJECT_ID \
--location="global" \
--workload-identity-pool="github-pool" \
--format="value(name)"
# Output format: projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/github-pool/providers/github-provider
```
### 4. Add Secrets to GitHub
```
GCP_PROJECT_ID = your-gcp-project
GCP_WORKLOAD_IDENTITY_PROVIDER = projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/github-pool/providers/github-provider
GCP_SERVICE_ACCOUNT = github-packer@your-gcp-project.iam.gserviceaccount.com
```
---
## Azure Setup
### 1. Create Resource Group
```bash
az group create --name luxfi-images --location eastus
```
### 2. Create App Registration
```bash
# Create app registration
az ad app create --display-name "GitHub Actions Lux Packer"
# Get the app ID
APP_ID=$(az ad app list --display-name "GitHub Actions Lux Packer" --query "[0].appId" -o tsv)
# Create service principal
az ad sp create --id $APP_ID
# Create client secret
az ad app credential reset --id $APP_ID --display-name "github-actions"
```
### 3. Assign Permissions
```bash
SUBSCRIPTION_ID=$(az account show --query id -o tsv)
RESOURCE_GROUP="luxfi-images"
# Grant Contributor on resource group
az role assignment create \
--assignee $APP_ID \
--role "Contributor" \
--scope "/subscriptions/$SUBSCRIPTION_ID/resourceGroups/$RESOURCE_GROUP"
# Grant permissions to create VMs (for Packer)
az role assignment create \
--assignee $APP_ID \
--role "Virtual Machine Contributor" \
--scope "/subscriptions/$SUBSCRIPTION_ID"
```
### 4. Create Shared Image Gallery (Optional)
```bash
# Create gallery for image distribution
az sig create \
--resource-group $RESOURCE_GROUP \
--gallery-name luxdGallery
# Create image definition
az sig image-definition create \
--resource-group $RESOURCE_GROUP \
--gallery-name luxdGallery \
--gallery-image-definition luxd \
--publisher luxfi \
--offer luxd \
--sku node \
--os-type Linux \
--os-state Generalized \
--hyper-v-generation V2
```
### 5. Add Secrets to GitHub
```
AZURE_CLIENT_ID = <App ID from step 2>
AZURE_CLIENT_SECRET = <Secret from step 2>
AZURE_TENANT_ID = <Your Azure AD tenant ID>
AZURE_SUBSCRIPTION_ID = <Your subscription ID>
AZURE_RESOURCE_GROUP = luxfi-images
```

# Native Build Infrastructure
## Cluster Ownership (NO MIXING)
| Cluster | Org | Purpose |
|---------|-----|---------|
| **lux-k8s** | `luxfi` | Lux blockchain infrastructure + CI runners |
| **hanzo-k8s** | `hanzoai` | Hanzo AI services + CI runners |
## lux-k8s ARC Setup
```
lux-k8s (do-sfo3-lux-k8s)
├── arc-system/ (ARC v0.13.1 controller)
│ └── lux-build listener (luxfi org)
└── lux-runners-amd64/ (1-4 auto-scaling nodes)
└── g-8vcpu-32gb nodes (dedicated CI, NoSchedule taint)
└── Ephemeral runner pods (Docker-in-Docker, 8 CPU / 28Gi)
```
## Platform Matrix — All Native
| Platform | Runner | Type |
|----------|--------|------|
| Linux amd64 | `lux-build` | Self-hosted on lux-k8s (8 CPU, 32Gi) |
| Linux arm64 | `ubuntu-24.04-arm` | GitHub-hosted native Ampere |
| macOS arm64 | `macos-latest` | GitHub-hosted native Apple Silicon |
| Windows x64 | `windows-latest` | GitHub-hosted native |
**Note**: DOKS sfo3 has no real ARM64 nodes (`g6_5` is premium AMD64, not Ampere).
Native arm64 builds use GitHub's Arm runners instead.
## Helm Releases (lux-k8s arc-system)
| Release | Chart | Purpose |
|---------|-------|---------|
| `arc` | gha-runner-scale-set-controller | ARC controller |
| `lux-build` | gha-runner-scale-set | amd64 runners for luxfi |

# GitHub Actions Release Workflow - Technical Explanation
## Overview
This document explains the technical implementation of the automated release workflow for Lux Node.
## Architecture
### Workflow Design Philosophy
The release workflow follows these principles:
1. **Single Responsibility**: Each job does one thing well
2. **Reusable Components**: Leverages existing build workflows as reusable components
3. **Fail Fast**: Version validation happens first before any builds
4. **Parallel Execution**: All platform builds run concurrently
5. **Atomic Release**: All artifacts collected before release creation
### Job Dependency Graph
```
┌──────────────────┐
│ validate-version │ (30s)
└────────┬─────────┘
│
┌────┴────┬───────────┬──────────┐
│ │ │ │
┌───▼────┐ ┌─▼─────┐ ┌───▼────┐ ┌──▼─────┐
│ubuntu │ │ubuntu │ │ macos │ │windows │ (10-15 min each)
│amd64 │ │arm64 │ │ │ │ │
└───┬────┘ └─┬─────┘ └───┬────┘ └──┬─────┘
└────────┴───────────┴──────────┘
│
┌──────▼────────┐
│create-release │ (2-3 min)
└───────────────┘
```
**Total Time**: ~15-20 minutes (parallel builds are the bottleneck)
## Job Details
### 1. validate-version
**Purpose**: Ensure semantic version is valid and < v2.0.0
**Outputs**:
- `version`: Version number without 'v' prefix (e.g., "1.20.1")
- `is_prerelease`: Boolean indicating if version is pre-release
**Logic**:
```bash
# Extract version from tag
TAG="${GITHUB_REF#refs/tags/}" # refs/tags/v1.20.1 → v1.20.1
VERSION="${TAG#v}" # v1.20.1 → 1.20.1
# Validate major version
MAJOR=$(echo "$VERSION" | cut -d. -f1) # 1.20.1 → 1
if [ "$MAJOR" -ge 2 ]; then
exit 1 # Fail workflow
fi
# Detect pre-release (contains - or +)
if echo "$VERSION" | grep -qE '[-+]'; then
is_prerelease=true
fi
```
**Why < v2.0.0?**
Go modules semantics require v2+ to use versioned import paths:
```go
// v1.x.x (current)
import "github.com/luxfi/node/vms"
// v2.x.x would require:
import "github.com/luxfi/node/v2/vms"
```
Enforcing v1.x.x prevents accidental breaking changes to import paths.
### 2. build-* Jobs
**Pattern**: Uses `uses: ./.github/workflows/build-*-release.yml`
**Why Reusable Workflows?**
- DRY principle: Don't duplicate build logic
- Maintainability: Update build logic in one place
- Consistency: Same build process for manual and automated releases
**Secrets Inheritance**:
```yaml
secrets: inherit
```
Passes all repository secrets to reusable workflows (AWS credentials, S3 buckets, etc.)
**Input Passing**:
```yaml
with:
tag: ${{ needs.validate-version.outputs.version }}
```
Some workflows accept tag as input for artifact naming.
### 3. create-release
**Purpose**: Collect all artifacts and create GitHub Release
**Steps**:
#### a. Download Artifacts
```yaml
uses: actions/download-artifact@v4
with:
path: ./artifacts
```
**Result**: All build artifacts downloaded to `./artifacts/`
**Directory Structure**:
```
./artifacts/
├── jammy/
│ └── luxd-v1.20.1-amd64.deb
├── focal/
│ └── luxd-v1.20.1-amd64.deb
└── build/
└── luxd-macos-v1.20.1.zip
```
#### b. Organize Files
Copies all artifacts to `./release/` directory with flat structure.
**Why Flatten?**
- Simpler asset URLs
- Easier for users to find files
- Consistent naming across platforms
#### c. Generate Checksums
```bash
cd ./release
sha256sum * > SHA256SUMS
```
**Format**:
```
a1b2c3d4... luxd-v1.20.1-amd64.deb
e5f6g7h8... luxd-macos-v1.20.1.zip
```
**User Verification**:
```bash
# Download file and checksums
curl -LO <file-url>
curl -LO <checksums-url>
# Verify
grep <filename> SHA256SUMS | sha256sum -c
```
#### d. Generate Changelog
Uses git log between previous tag and current:
```bash
PREV_TAG=$(git describe --tags --abbrev=0 HEAD^)
git log --pretty=format:"- %s (%h)" ${PREV_TAG}..HEAD
```
**Output Format**:
```markdown
## What's Changed
- Add new feature X (abc123)
- Fix bug in Y component (def456)
- Update dependencies (ghi789)
**Full Changelog**: https://github.com/luxfi/node/compare/v1.20.0...v1.20.1
```
#### e. Create Release
Uses `gh` CLI for release creation:
```bash
gh release create "v1.20.1" \
./release/* \
--title "Lux Node v1.20.1" \
--notes-file CHANGELOG.md \
--latest # or --prerelease for pre-releases
```
**Why gh CLI?**
- Official GitHub tool
- Handles authentication automatically
- Simpler than REST API
- Uploads all files in one command
## Workflow Triggers
### Tag Pattern Matching
```yaml
on:
push:
tags:
- 'v[0-1].*.*'
```
**Pattern Breakdown**:
- `v` - Literal 'v' character
- `[0-1]` - Major version 0 or 1
- `.*` - Any minor version
- `.*` - Any patch version
**Matches**:
- ✅ `v1.0.0` (first release)
- ✅ `v1.20.1` (production release)
- ✅ `v1.99.999` (high version numbers)
- ✅ `v1.20.1-rc.1` (release candidate)
- ✅ `v1.20.1+build.123` (build metadata)
**Rejects**:
- ❌ `v2.0.0` (major version 2)
- ❌ `v3.1.0` (major version 3)
- ❌ `1.20.1` (missing 'v' prefix)
- ❌ `version-1.20.1` (wrong format)
## Pre-release Detection
**Logic**:
```bash
if echo "$VERSION" | grep -qE '[-+]'; then
is_prerelease=true
fi
```
**Semantic Versioning**:
- `-` indicates pre-release: `1.20.1-rc.1`, `1.20.1-beta.2`
- `+` indicates build metadata: `1.20.1+build.123`
**GitHub Behavior**:
- Pre-releases: Shown with "Pre-release" badge, not marked as "Latest"
- Stable releases: Shown with "Latest release" badge
## Artifact Naming Conventions
Each platform has its own naming scheme:
| Platform | Pattern | Example |
|----------|---------|---------|
| Ubuntu AMD64 | `luxd-{version}-amd64.deb` | `luxd-v1.20.1-amd64.deb` |
| Ubuntu ARM64 | `luxd-{version}-arm64.deb` | `luxd-v1.20.1-arm64.deb` |
| macOS | `luxd-macos-{version}.zip` | `luxd-macos-v1.20.1.zip` |
| Windows | `node-win-{version}.zip` | `node-win-v1.20.1.zip` |
**Why Different Patterns?**
- Historical convention from existing build scripts
- Platform-specific package managers expect different formats
- Windows uses `node` instead of `luxd` (legacy naming)
## Error Handling
### Build Failure
**Scenario**: One platform build fails
**Behavior**:
- `create-release` job never runs (depends on all builds)
- Workflow marked as failed
- No partial release created
**Recovery**:
1. Fix build issue
2. Delete failed tag: `git tag -d v1.20.1 && git push --delete origin v1.20.1`
3. Re-tag and push
### Partial Artifact Collection
**Scenario**: Some artifacts missing during collection
**Behavior**:
- `Organize release files` step silently skips missing files (`|| true`)
- Release created with available artifacts
- Missing platforms will have no binary attached
**Detection**:
- Check `Release summary` in job output
- Verify all expected platforms in asset list
**Recovery**:
1. Identify which build workflow failed
2. Fix workflow
3. Manually trigger failed workflow with same tag
4. Download new artifacts
5. Upload to existing release: `gh release upload v1.20.1 <file>`
## Performance Optimization
### Parallel Builds
All platform builds run simultaneously:
```yaml
build-ubuntu-amd64:
needs: validate-version
# ...
build-ubuntu-arm64:
needs: validate-version
# ...
# All depend only on validate-version, not each other
```
**Time Savings**:
- Sequential: ~60 minutes (4 platforms × 15 min each)
- Parallel: ~15 minutes (longest build time)
- **Improvement**: 75% faster
### Shallow Checkout
Most jobs use default shallow checkout (depth=1):
```yaml
- uses: actions/checkout@v4
```
**Exception**: `create-release` job needs full history for changelog:
```yaml
- uses: actions/checkout@v4
with:
fetch-depth: 0
```
## Security Considerations
### Minimal Permissions
```yaml
permissions:
contents: write # Create releases, upload assets
id-token: write # OIDC for AWS authentication
```
**Not Granted**:
- `actions: write` - Cannot modify workflows
- `packages: write` - Cannot publish packages
- `issues: write` - Cannot create issues
### Secret Handling
All secrets passed via `secrets: inherit`:
```yaml
build-ubuntu-amd64:
secrets: inherit # Passes AWS_DEPLOY_SA_ROLE_ARN, BUCKET
```
**Best Practice**: Never log secrets, never use in conditionals
### Checksum Verification
Forces users to verify downloads:
```bash
# Generate checksums
sha256sum * > SHA256SUMS
# Users verify with:
sha256sum -c SHA256SUMS
```
## Testing Strategy
### Manual Test Tag
Create test release without polluting real releases:
```bash
# Use version with "test" keyword
git tag -a v1.99.99-test -m "Test release workflow"
git push origin v1.99.99-test
# Monitor: https://github.com/luxfi/node/actions
# Cleanup after testing
git push --delete origin v1.99.99-test
git tag -d v1.99.99-test
gh release delete v1.99.99-test --yes
```
### Automated Test Script
Use included test script:
```bash
./scripts/test-release-workflow.sh 1.99.99-test
```
**Script Features**:
- Version validation
- Git cleanliness check
- Tag conflict detection
- Workflow monitoring
- Automatic cleanup
## Debugging
### Enable Debug Logging
Add to workflow:
```yaml
env:
ACTIONS_STEP_DEBUG: true
ACTIONS_RUNNER_DEBUG: true
```
### Check Job Logs
1. Visit workflow run: https://github.com/luxfi/node/actions/workflows/release.yml
2. Click specific run
3. Expand failed job
4. Read error messages
### Common Issues
**Issue**: "Resource not accessible by integration"
- **Cause**: Missing `contents: write` permission
- **Fix**: Add permission to workflow
**Issue**: "Unable to download artifact"
- **Cause**: Artifact name mismatch
- **Fix**: Check `upload-artifact` name in build workflow
**Issue**: "gh: command not found"
- **Cause**: GitHub CLI not installed in runner
- **Fix**: Add `- uses: cli/gh-action@v2` or use gh CLI pre-installed
## Future Enhancements
### Potential Improvements
1. **Docker Image Publishing**: Add Docker build job
2. **Homebrew Formula Update**: Auto-update brew formula
3. **Release Notes Template**: Use `.github/release-template.md`
4. **Asset Signing**: GPG sign all binaries
5. **Download Stats**: Track download metrics
6. **Auto-changelog**: Generate from commit conventions
7. **Slack Notification**: Notify team on release
8. **Rollback Support**: Tag previous version as latest if needed
### Metrics to Track
- Build time per platform
- Artifact size trends
- Download counts per platform
- Release frequency
- Time to production

# Release Workflow Documentation
## Overview
The `release.yml` workflow automates building and publishing Lux Node binaries for all platforms when semantic version tags are pushed.
## Workflow Architecture
### 1. Trigger Mechanism
**Tag Pattern**: `v[0-1].*.*`
- ✅ Accepts: `v1.0.0`, `v1.20.1`, `v1.999.999`, `v1.20.1-rc.1`
- ❌ Rejects: `v2.0.0`, `v2.1.0`, `v3.0.0` (requires `/v2` import path per Go modules)
**Rationale**: Go modules require major version 2+ to use `/v2`, `/v3` etc. in import paths. Since Lux uses `github.com/luxfi/node` (no version suffix), we enforce v1.x.x only.
### 2. Job Flow
```
validate-version (validates tag < v2.0.0)
├─> build-ubuntu-amd64 ───┐
├─> build-ubuntu-arm64 ───┤
├─> build-macos ──────────┼──> create-release (combines all artifacts)
└─> build-windows ────────┘
```
### 3. Platform Builds
Uses **reusable workflows** (existing build-*-release.yml files):
| Platform | Workflow | Artifact Name | Binary Format |
|----------|----------|---------------|---------------|
| Linux AMD64 (Ubuntu 22.04) | `build-ubuntu-amd64-release.yml` | `jammy` | `.deb` package |
| Linux AMD64 (Ubuntu 20.04) | `build-ubuntu-amd64-release.yml` | `focal` | `.deb` package |
| Linux ARM64 (Ubuntu 22.04) | `build-ubuntu-arm64-release.yml` | `jammy` | `.deb` package |
| Linux ARM64 (Ubuntu 20.04) | `build-ubuntu-arm64-release.yml` | `focal` | `.deb` package |
| macOS (Universal) | `build-macos-release.yml` | `build` | `.zip` archive |
| Windows AMD64 | `build-win-release.yml` | Various | `.exe` or `.zip` |
### 4. Release Creation
**GitHub Release includes**:
- All platform binaries
- `SHA256SUMS` checksum file
- Auto-generated changelog (git log since previous tag)
- Pre-release flag (if version contains `-` or `+`)
- "Latest" badge (for stable releases only)
## Usage
### Creating a Release
1. **Tag the commit**:
```bash
git tag -a v1.20.1 -m "Release v1.20.1"
git push origin v1.20.1
```
2. **Monitor workflow**:
- Visit: https://github.com/luxfi/node/actions/workflows/release.yml
- Watch all build jobs complete (typically 15-20 minutes)
3. **Verify release**:
- Visit: https://github.com/luxfi/node/releases
- Check all platform binaries are attached
- Verify SHA256SUMS file
### Pre-release Creation
For release candidates or beta versions:
```bash
git tag -a v1.20.1-rc.1 -m "Release Candidate 1 for v1.20.1"
git push origin v1.20.1-rc.1
```
**Behavior**:
- Creates GitHub Release with "Pre-release" badge
- Does NOT mark as "Latest"
- Changelog includes "(Pre-release)" note
### Deleting a Failed Release
If a release fails and needs to be retried:
```bash
# Delete remote tag
git push --delete origin v1.20.1
# Delete local tag
git tag -d v1.20.1
# Delete GitHub Release (via web UI or gh CLI)
gh release delete v1.20.1 --yes
# Fix issues, then re-tag and push
git tag -a v1.20.1 -m "Release v1.20.1"
git push origin v1.20.1
```
## Testing the Workflow
### Dry Run (Test Tag)
Create a test tag to verify workflow without publishing:
```bash
# Create test tag locally
git tag -a v1.99.99-test -m "Test release workflow"
# Push to remote (triggers workflow)
git push origin v1.99.99-test
# After testing, clean up
git push --delete origin v1.99.99-test
git tag -d v1.99.99-test
gh release delete v1.99.99-test --yes
```
### Local Validation
Test semver validation logic locally:
```bash
# Test valid versions
for ver in 1.0.0 1.20.1 1.999.999 "1.20.1-rc.1"; do
MAJOR=$(echo "$ver" | cut -d. -f1)
if [ "$MAJOR" -ge 2 ]; then
echo "✗ v${ver}: REJECT"
else
echo "✓ v${ver}: ACCEPT"
fi
done
# Test invalid versions
for ver in 2.0.0 2.1.0 3.0.0; do
MAJOR=$(echo "$ver" | cut -d. -f1)
if [ "$MAJOR" -ge 2 ]; then
echo "✓ v${ver}: REJECT (correct)"
else
echo "✗ v${ver}: ACCEPT (should reject)"
fi
done
```
## Troubleshooting
### Issue: "Version >= v2.0.0" Error
**Cause**: Attempted to tag v2.x.x or higher
**Solution**: Use v1.x.x versions only. For v2+, update import paths to `github.com/luxfi/node/v2` throughout codebase first.
### Issue: Build Workflow Fails
**Symptoms**: `create-release` job never runs
**Diagnosis**:
1. Check individual build job logs
2. Common issues:
- AWS credentials expired (check secrets)
- Build script failures (check `./scripts/run_task.sh build`)
- Dependency resolution issues
**Solution**:
1. Fix build issues in individual workflow
2. Delete failed release tag
3. Re-tag and push
### Issue: Missing Artifacts
**Symptoms**: Some platform binaries not attached to release
**Diagnosis**:
1. Check `Download all artifacts` step in `create-release` job
2. Verify artifact names match expected patterns
**Solution**:
1. Update `Organize release files` step to match actual artifact structure
2. Check individual build workflows upload artifacts correctly
### Issue: Changelog Empty
**Symptoms**: Release notes say "Initial Release" but previous tags exist
**Cause**: Shallow git checkout (missing history)
**Solution**: Workflow uses `fetch-depth: 0` to fetch full history. If issue persists:
1. Check git repository configuration
2. Verify previous tags are pushed to remote
## Security Considerations
### Permissions
Workflow requires minimal permissions:
- `contents: write` - Create releases and upload assets
- `id-token: write` - AWS OIDC authentication (for build workflows)
### Secrets Required
All secrets inherited from repository settings:
- `AWS_DEPLOY_SA_ROLE_ARN` - AWS role for S3 uploads (build workflows)
- `BUCKET` - S3 bucket name (build workflows)
- `GITHUB_TOKEN` - Automatically provided by GitHub Actions
### Checksum Verification
Users can verify downloads:
```bash
# Download release binary and SHA256SUMS
curl -LO https://github.com/luxfi/node/releases/download/v1.20.1/luxd-macos-v1.20.1.zip
curl -LO https://github.com/luxfi/node/releases/download/v1.20.1/SHA256SUMS
# Verify checksum
grep luxd-macos-v1.20.1.zip SHA256SUMS | sha256sum -c
```
## Workflow Outputs
### GitHub Release
**URL Format**: `https://github.com/luxfi/node/releases/tag/v{VERSION}`
**Contains**:
- Release title: "Lux Node v{VERSION}"
- Changelog: Auto-generated from git commits
- Assets:
- `luxd-{version}-amd64.deb` (Ubuntu 22.04)
- `luxd-{version}-amd64.deb` (Ubuntu 20.04)
- `luxd-{version}-arm64.deb` (Ubuntu 22.04)
- `luxd-{version}-arm64.deb` (Ubuntu 20.04)
- `luxd-macos-{version}.zip`
- `node-win-{version}.zip` or `.exe`
- `SHA256SUMS`
### Job Summary
GitHub Actions summary page shows:
- Release version
- Platform artifact table (file names, sizes)
- SHA256 checksums
- Link to release page
## Maintenance
### Adding New Platforms
To add a new platform (e.g., FreeBSD):
1. Create new build workflow: `.github/workflows/build-freebsd-release.yml`
2. Add job to `release.yml`:
```yaml
build-freebsd:
needs: validate-version
uses: ./.github/workflows/build-freebsd-release.yml
secrets: inherit
```
3. Update `create-release` job dependencies:
```yaml
needs:
- validate-version
- build-ubuntu-amd64
- build-ubuntu-arm64
- build-macos
- build-windows
- build-freebsd # Add here
```
4. Update artifact collection logic in `Organize release files` step
### Updating Changelog Format
Edit the `Generate changelog` step:
```yaml
- name: Generate changelog
run: |
# Custom changelog format
git log --pretty=format:"- **%s** by @%an (%h)" ${PREV_TAG}..HEAD > CHANGELOG.md
```
### Customizing Release Title
Edit the `Create GitHub Release` step:
```yaml
FLAGS="--title \"Lux Network Node ${TAG} - Codename XYZ\""
```

# Contributing to Lux Node
Thank you for your interest in contributing to Lux Node! This document provides guidelines and instructions for contributing to the project.
To start developing on Lux Node, you'll need a few things installed.
- Golang version >= 1.23.9
- gcc
- g++
On MacOS, a modern version of bash is required (e.g. via [homebrew](https://brew.sh/) with `brew install bash`). The version installed by default is not compatible with Lux Node's [shell scripts](scripts).
## Running tasks
This repo uses the [Task](https://taskfile.dev/) task runner to simplify usage and discoverability of development tasks. To list available tasks:
```bash
./scripts/run_task.sh
```
## Issues
We are committed to fostering a welcoming and inclusive community. Please be respectful and considerate in all interactions.
- Do not open up a GitHub issue if it relates to a security vulnerability in Lux Node, and instead refer to our [security policy](./SECURITY.md).
- Use welcoming and inclusive language
- Be respectful of differing viewpoints and experiences
- Gracefully accept constructive criticism
- Focus on what is best for the community
- Show empathy towards other community members
## Getting Started
### Prerequisites
- Go 1.21.12 or higher
- Git
- Make
- GCC/G++ compiler
### Setting Up Your Development Environment
- If you want to start a discussion about the development of a new feature or the modification of an existing one, start a thread under GitHub [discussions](https://github.com/luxfi/node/discussions/categories/ideas).
- Post a thread about your idea and why it should be added to Lux Node.

./scripts/run_task.sh generate-protobuf
```
#### Autogenerated mocks
💁 The general direction is to **reduce** usage of mocks, so use the following with moderation.
Mocks are auto-generated using [mockgen](https://pkg.go.dev/go.uber.org/mock/mockgen) and `//go:generate` commands in the code.
- To **re-generate all mocks**, use the command below from the root of the project:
```sh
./scripts/run_task.sh generate-mocks
```
- To **add** an interface that needs a corresponding mock generated:
- if the file `mocks_generate_test.go` exists in the package where the interface is located, either:
- modify its `//go:generate go run go.uber.org/mock/mockgen` to generate a mock for your interface (preferred); or
- add another `//go:generate go run go.uber.org/mock/mockgen` to generate a mock for your interface according to specific mock generation settings
- if the file `mocks_generate_test.go` does not exist in the package where the interface is located, create it with content (adapt as needed):
```go
// Copyright (C) 2019-2025, Lux Industries, Inc. All rights reserved.
// See the file LICENSE for licensing terms.
package mypackage
//go:generate go run go.uber.org/mock/mockgen -package=${GOPACKAGE} -destination=mocks_test.go . YourInterface
```
Notes:
1. Ideally generate all mocks to `mocks_test.go` for the package you need to use the mocks for and do not export mocks to other packages. This reduces package dependencies, reduces production code pollution and forces to have locally defined narrow interfaces.
1. Prefer using reflect mode to generate mocks than source mode, unless you need a mock for an unexported interface, which should be rare.
- To **remove** an interface from having a corresponding mock generated:
1. Edit the `mocks_generate_test.go` file in the directory where the interface is defined
1. If the `//go:generate` mockgen command line:
- generates a mock file for multiple interfaces, remove your interface from the line
- generates a mock file only for the interface, remove the entire line. If the file is empty, remove `mocks_generate_test.go` as well.

## Architecture
### Multi-Chain Design
Primary network (P/X/C) uses Quasar consensus via `luxfi/consensus`.
All new native chains use Quasar (BLS + Corona + ML-DSA). No snow/snowball.
| Chain | Purpose | VM | Consensus |
|-------|---------|-----|-----------|
| **P-Chain** | Staking, validators, L1 validators | PlatformVM | Quasar |
| **X-Chain** | UTXO-based asset exchange | XVM | Quasar |
| **C-Chain** | EVM smart contracts | EVM | Quasar |
| **A-Chain** | AI inference, model registry | AIVM | Quasar |
| **B-Chain** | Cross-chain bridge operations | BridgeVM | Quasar |
| **D-Chain** | DEX (order book, perpetuals) | DexVM | Quasar |
| **G-Chain** | On-chain graph database | GraphVM | Quasar |
| **I-Chain** | Decentralized identity (DID/VC) | IdentityVM | Quasar |
| **K-Chain** | Post-quantum key management | KeyVM | Quasar |
| **M-Chain** | Threshold signing (MPC) | ThresholdVM | Quasar |
| **O-Chain** | Oracle price feeds | OracleVM | Quasar |
| **Q-Chain** | Post-quantum consensus coordination | QuantumVM | Quasar |
| **R-Chain** | Cross-chain message relay | RelayVM | Quasar |
| **S-Chain** | Service node coordination | ServiceNodeVM | Quasar |
| **T-Chain** | Cross-chain teleport (bridge+relay+oracle) | TeleportVM | Quasar |
| **Z-Chain** | Zero-knowledge proofs (FHE) | ZKVM | Quasar |
### Consensus Layer
Located in `/consensus/` (separate package `github.com/luxfi/consensus`):
- **Quasar**: Production consensus -- BLS12-381 + Corona (lattice) + ML-DSA-65 (FIPS 204)
- **Chain Engine**: Linear blockchain consensus (Nova sub-protocol)
- **DAG Engine**: Directed acyclic graph for parallel processing (Nebula sub-protocol)
- **PQ Engine**: Post-quantum finality layer
Sub-protocols: Photon (sampling) -> Wave (voting) -> Focus (confidence) -> Ray/Field (finality)
### Virtual Machines
Located in `/vms/`:
- **platformvm**: Staking, validation, network management
- **xvm**: Asset transfers, UTXO model
- **dexvm**: DEX with order book, perpetuals, AMM
- **thresholdvm**: Threshold MPC and FHE for confidential computing
- **quantumvm**: PQ consensus coordination (ML-DSA, Corona)
- **identityvm**: Decentralized identity (DID, verifiable credentials)
- **keyvm**: Post-quantum key management (ML-KEM, ML-DSA)
- **bridgevm**: Cross-chain bridge with MPC attestation
- **oraclevm**: Decentralized oracle network
- **aivm**: AI inference verification
- **graphvm**: On-chain graph database
- **relayvm**: Cross-chain message relay
- **servicenodevm**: Service node epoch management
- **teleportvm**: Unified bridge+relay+oracle
- **zkvm**: Zero-knowledge proof verification
- **proposervm**: Block proposer wrapper VM
### Key Interfaces
**p2p.Sender** (from `github.com/luxfi/p2p`):
```go
type Sender interface {
SendRequest(ctx context.Context, nodeIDs set.Set[ids.NodeID], requestID uint32, request []byte) error
SendResponse(ctx context.Context, nodeID ids.NodeID, requestID uint32, response []byte) error
SendError(ctx context.Context, nodeID ids.NodeID, requestID uint32, errorCode int32, errorMessage string) error
SendGossip(ctx context.Context, config SendConfig, msg []byte) error
}
```
**Keychain Interfaces** (from `github.com/luxfi/keychain`):
```go
type Signer interface {
SignHash([]byte) ([]byte, error)
Sign([]byte) ([]byte, error)
Address() ids.ShortID
}
type Keychain interface {
Get(addr ids.ShortID) (Signer, bool)
Addresses() set.Set[ids.ShortID]
}
```
## Package Dependencies
### CRITICAL: Use Lux packages only
- ✅ `github.com/luxfi/node`
- ✅ `github.com/luxfi/geth` (NOT go-ethereum)
- ✅ `github.com/luxfi/consensus`
- ✅ `github.com/luxfi/keychain`
- ✅ `github.com/luxfi/ledger`
- ✅ `github.com/luxfi/lattice` (FHE)
- ❌ `github.com/ava-labs/*`
- ❌ `github.com/ethereum/go-ethereum`
### Import Aliasing
Avoid conflicts with consensus packages:
```go
import (
platformblock "github.com/luxfi/node/vms/platformvm/block"
consensusblock "github.com/luxfi/consensus/engine/chain"
)
```
## Token Denomination
LUX uses **6 decimals** (microLUX base unit) on P-Chain/X-Chain:
| Unit | Value |
|------|-------|
| µLUX (MicroLux) | 1 (base) |
| mLUX (MilliLux) | 1,000 |
| LUX | 1,000,000 |
| TLUX (TeraLux) | 10^18 |
**Supply Cap**: 2 trillion LUX (2 × 10^18 µLUX)
C-Chain uses standard EVM 18 decimals (Wei).
See `utils/units/lux.go` for constants.
## Key Technical Decisions
### Genesis Architecture
```
github.com/luxfi/genesis (JSON config) → github.com/luxfi/node/genesis/builder (type conversion)
```
- Genesis package has no node dependencies
- Builder package handles type conversions (string → ids.NodeID, uint64 → time.Duration)
### CGO Dependencies
These require CGO for full functionality (graceful fallback when disabled):
- `consensus/quasar` - GPU NTT acceleration
- `vms/thresholdvm/fhe` - GPU FHE operations
- `x/blockdb` - zstd compression
### FHE (Fully Homomorphic Encryption)
Located in `vms/thresholdvm/fhe/`:
- Uses `github.com/luxfi/lattice/multiparty` for DKG
- Lattice-based cryptography only (no fallbacks)
- Threshold decryption via Warp messaging
**Precompile Addresses:**

### ZAP Transport (Zero-Copy App Proto)
ZAP is the default high-performance binary wire protocol for VM<->Node communication.
gRPC support is available via build tag for testing/compatibility.
**Build Tags:**
```bash
go build # ZAP only (default, production)
go build -tags=grpc # gRPC support (for testing/compatibility)
```
**Key Packages:**
- `github.com/luxfi/api/zap` - Core wire protocol and message types
- `github.com/luxfi/vm/rpc/sender` - p2p.Sender over ZAP/gRPC
- `vms/rpcchainvm/sender/` - Node-side sender implementation
- `vms/platformvm/warp/zwarp/` - ZAP-based warp signing client/server
**Wire Protocol Format:**
```
[4 bytes: length][1 byte: message type][payload...]
```
**Performance Benefits:**
- Zero-copy serialization (buffer pooling via sync.Pool)
- ~5-10x faster serialization than protobuf
- ~2-3x lower latency (no HTTP/2 overhead)
- ~30-50% CPU reduction on hot paths
**Sender Usage:**
```go
// ZAP transport (default)
s := sender.ZAP(zapConn)
// gRPC transport (requires -tags=grpc build)
s := sender.GRPC(senderpb.NewSenderClient(grpcConn))
```
**Warp over ZAP:**
The `zwarp` package implements warp signing via ZAP:
```go
// Client implements warp.Signer over ZAP
client := zwarp.NewClient(zapConn)
sig, err := client.Sign(unsignedMsg)
// BatchSign for HFT optimization
sigs, errs := client.BatchSign(messages)
```
## RNS Transport (Reticulum Network Stack)
The node supports RNS as an alternative transport layer alongside TCP/IP, enabling mesh networking, LoRa connectivity, and offline-first validator operation.
**Specification**: [LP-9701](../lps/LPs/lp-9701-reticulum-network-stack.md)
### Endpoint Types
The `net/endpoints` package supports three addressing modes:
```go
// IP address
endpoint := endpoints.NewIPEndpoint(netip.MustParseAddrPort("203.0.113.50:9631"))
// Hostname (DNS resolved)
endpoint, _ := endpoints.NewHostnameEndpoint("validator.example.com", 9631)
// RNS destination (mesh/LoRa)
endpoint, _ := endpoints.NewRNSEndpointFromHex("rns://a5f72c3d4e5f60718293a4b5c6d7e8f9")
```
### Key Files
| File | Purpose |
|------|---------|
| `net/endpoints/endpoint.go` | Unified endpoint abstraction (IP, hostname, RNS) |
| `network/dialer/rns_transport.go` | RNS transport implementation |
| `network/dialer/rns_identity.go` | Classical identity (Ed25519 + X25519) |
| `network/dialer/rns_identity_pq.go` | Hybrid PQ identity (+ ML-DSA + ML-KEM) |
| `network/dialer/rns_link.go` | Encrypted link protocol with PQ support |
| `network/dialer/rns_announce.go` | Destination discovery and announcements |
### Configuration
```yaml
# ~/.lux/config.yaml
rns:
enabled: true
configPath: ~/.lux/reticulum
announceInterval: 5m
interfaces:
- AutoInterface
- TCPClientInterface
linkTimeout: 30s
postQuantum: true # Enable hybrid PQ mode
requirePostQuantum: false # Allow classical-only peers
```
## Post-Quantum Cryptography (Hybrid Mode)
RNS transport supports hybrid post-quantum cryptography combining classical algorithms with NIST-standardized post-quantum primitives (TLS 1.3-like approach).
### Cryptographic Suite
| Purpose | Classical | Post-Quantum | Security |
|---------|-----------|--------------|----------|
| Identity Signing | Ed25519 | ML-DSA-65 | NIST Level 3 |
| Key Exchange | X25519 | ML-KEM-768 | NIST Level 3 |
| Session Encryption | AES-256-GCM | - | 256-bit |
| Key Derivation | HKDF-SHA256 | - | - |
### Forward Secrecy
- **Ephemeral Keys**: Fresh X25519 + ML-KEM keypairs generated per session
- **Key Destruction**: Ephemeral private keys zeroed after handshake
- **Hybrid Derivation**: `combined_secret = X25519_shared || ML_KEM_shared`
- **Defense-in-Depth**: Secure if either algorithm remains unbroken
### Wire Format Sizes
| Component | Classical | Hybrid | Delta |
|-----------|-----------|--------|-------|
| Public Identity | 64 bytes | ~3.2 KB | +3.1 KB |
| Signature | 64 bytes | ~2.5 KB | +2.4 KB |
| Key Exchange | 64 bytes | ~1.2 KB | +1.1 KB |
| Handshake Total | ~256 bytes | ~7.5 KB | +7.2 KB |
### Backward Compatibility
- **Capability Exchange**: Handshake advertises PQ support
- **Graceful Fallback**: Falls back to classical if peer lacks PQ
- **Mixed Networks**: PQ and classical validators coexist
- **Policy Enforcement**: `requirePostQuantum: true` rejects classical peers
### Testing PQ Forward Secrecy
```bash
# Run hybrid PQ tests
go test -v -run "TestHybrid" ./node/network/dialer/... -count=1
# Key tests:
# - TestHybridIdentity_SignVerify (ML-DSA-65 signatures)
# - TestHybridIdentity_Encapsulate_Decapsulate (ML-KEM-768)
# - TestHybridRNSLink_Handshake (full hybrid handshake)
# - TestHybridRNSLink_ForwardSecrecy (ephemeral key destruction)
# - TestHybridToClassical_Fallback (backward compatibility)
```
## Common Gotchas
### 1. P2P Sender Interface
Node's rpcchainvm implements `p2p.Sender` (from `github.com/luxfi/p2p`) for cross-chain messaging.
The `sender` package is a gRPC implementation of `p2p.Sender`.
### 2. Chain Tracking
Nodes don't automatically track chains. Use:
```bash
--track-chains=<ChainID>
```
Or create config: `~/.lux/runs/.../node*/chainConfigs/<ChainID>.json`
### 3. Genesis blobSchedule
Mainnet genesis requires Cancun fork config:
```json
"blobSchedule": {
"cancun": {
"max": 6,
"target": 3,
"baseFeeUpdateFraction": 3338477
}
}
```
### 4. Network Snapshots
CLI creates new directories on restart. Use snapshots:
```bash
lux network save --snapshot-name <name>
lux network start --snapshot-name <name>
```
### 5. EIP-3860 Historic Blocks
For importing pre-merge blocks, Shanghai must be active based on `ShanghaiTime`, not merge status.
### 6. Genesis Hash Mismatch on Restart
**Problem**: "db contains invalid genesis hash" error when restarting nodes.
**Cause**: Genesis bytes are rebuilt from JSON config on each start. Due to non-deterministic JSON serialization (map iteration order), the rebuilt bytes differ from the original, causing hash mismatch.
**Solution**: Genesis bytes are now cached to `genesis.bytes` file in the node's data directory. On subsequent restarts, the cached bytes are used directly. This happens automatically when using `--genesis-file`.
### 7. VM Config Format Mismatch
**Problem**: "failed to parse config: unknown codec version" for T-Chain (ThresholdVM) or Z-Chain (ZKVM) in dev mode.
**Cause**: Two issues:
1. Genesis builder passes JSON config (`{"version":1,"message":"..."}`) to VMs that expect binary codec format
2. Dev mode's automining config injection converts all chain configs to JSON, breaking binary-codec VMs
**Solution**:
- `genesis/builder/builder.go`: T-Chain and Z-Chain use `[]byte(config.TChainGenesis)` (empty bytes for defaults) instead of `getGenesis()` which returns JSON
- `chains/manager.go`: `injectAutominingConfig` only injects for `EVMID`, skipping binary-codec VMs
**Alternative**: Use `--genesis-raw-bytes` flag to pass base64-encoded pre-built genesis bytes directly.

## Security Notes
### Mainnet Readiness (2025-12-31)
- Memory exhaustion protection (IP tracker limits, bloom filter caps)
- BLS signature CGO/pure-Go consistency
- Replay attack prevention with timestamp validation
- Safe math in DEX operations
### 11. P-Chain Block Sync (isMissingContextError "not found")
**Problem**: New validator node stays at P-chain height 0 even after connecting to testnet peers. Blocks received via Put/PushQuery are silently discarded.
**Root Cause**: `HandleIncomingBlock` returns `"not found"` when the block's parent isn't in the local state. `isMissingContextError` didn't recognize `"not found"` as a missing-context condition, so `requestContext` (GetAncestors) was never called.
**Fix** in `chains/manager.go`, `isMissingContextError`:
```go
// Added "not found" pattern:
strings.Contains(errStr, "not found") // parent block not in local state
```
**Effect**: Now when a block arrives whose parent is unknown, the handler sends `GetAncestors` to the peer, receives the full ancestor chain, and processes blocks in order, advancing the P-chain height.
**Note**: The network layer (`network.go:sequencerID`) already correctly maps native chain IDs (P, C, X, etc.) to `PrimaryNetworkID` for validator set lookups — no separate gossip fix needed.
### Known CGO Stubs
When CGO disabled, these use CPU fallbacks:
- `consensus/quasar/gpu_ntt_nocgo.go`
- `vms/thresholdvm/fhe/gpu_fhe_nocgo.go`
- `vms/zkvm/accel/accel_mlx.go`
### 8. ZAP CreateHandlers for VM HTTP Endpoints
**Problem**: C-chain and D-chain RPC endpoints returning 404 despite VMs running.
**Cause**: The `zap.Client` in `vms/rpcchainvm/zap/client.go` did not implement the `CreateHandlers` interface. The node checks for this interface to register HTTP handlers (like `/rpc`, `/ws`) with the HTTP server.
**Solution**: Added `CreateHandlers` method to `zap.Client` that:
1. Sends `MsgCreateHandlers` via ZAP wire protocol to the VM
2. Receives `CreateHandlersResponse` with list of handlers (prefix + server address)
3. Creates `httputil.NewSingleHostReverseProxy` for each handler
4. Returns `map[string]http.Handler` for registration
**File Modified**: `vms/rpcchainvm/zap/client.go`
**Verification**:
```bash
curl -s -X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \
http://localhost:9640/ext/bc/C/rpc
# Returns: {"jsonrpc":"2.0","id":1,"result":"0x17870"}
```
### 9. Root "/" Endpoint Handler
**Feature**: The node's root endpoint ("/") provides EVM compatibility and node information.
**Behavior**:
- **GET /**: Returns JSON node information (nodeId, networkId, version, chains, endpoints)
- **POST /**: Proxies JSON-RPC requests directly to C-chain `/ext/bc/C/rpc`
- **OPTIONS /**: Returns CORS preflight headers
**Files Modified**: `server/http/router.go`, `server/http/server.go`
**Types**:
```go
type RootInfo struct {
NodeID string `json:"nodeId,omitempty"`
NetworkID uint32 `json:"networkId,omitempty"`
Version string `json:"version,omitempty"`
Ready bool `json:"ready"`
Chains struct { C, P, X string } `json:"chains"`
Endpoints struct { RPC, Websocket, Info, Health string } `json:"endpoints"`
}
type RootInfoProvider interface {
GetRootInfo() RootInfo
}
```
**Usage**:
```bash
# Get node info
curl http://localhost:9650/
# Send EVM JSON-RPC directly to root (proxied to C-chain)
curl -X POST -H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \
http://localhost:9650/
```
**Implementation Notes**:
- The Server interface exposes `SetRootInfoProvider(provider)` to configure node info
- When no provider is set, returns default endpoint paths
- POST errors return proper JSON-RPC error format if C-chain unavailable
### 10. BLS Key Not Loaded into Validators Manager
**Problem**: Health check shows "validator doesn't have a BLS key" despite BLS keys being correctly configured in genesis.
**Cause**: The `initValidatorSets()` function in `/vms/platformvm/state/state.go` was skipping validator population when `NumNets() != 0`. This happened because:
1. Network layer might pre-populate validators (without BLS keys) before state initialization
2. When `initValidatorSets()` runs, it sees validators exist and skips adding them with proper BLS keys
3. The health check queries `n.vdrs.GetValidator()` which returns validator with nil PublicKey
**Solution**: Modified `initValidatorSets()` to always add validators (not skip when `NumNets() != 0`). The `AddStaker` method replaces existing entries, so validators get updated with proper BLS keys.
**File Modified**: `vms/platformvm/state/state.go` (line ~2144)
**Before**:
```go
if s.validators.NumNets() != 0 {
// skip re-adding them here
return nil
}
```
**After**:
```go
if s.validators.NumNets() != 0 {
log.Info("initValidatorSets: validator manager not empty, will update with BLS keys")
}
// Continue to add validators with proper BLS keys
```
**Verification**:
```bash
curl -s http://localhost:9650/ext/health | jq '.checks.bls'
# Should show: "message": "node has the correct BLS key"
```
## Benchmark Results (Single Node)
Testing conducted on a single Lux validator node (testnet mode, macOS):
| Metric | Result |
|--------|--------|
| Sustained TPS | 1,091 TPS (60s benchmark) |
| Peak TPS | 1,094 TPS (5 workers) |
| Query Performance | 840 queries/sec |
| Query Latency | 17.67ms avg |
| Optimal Concurrency | 5 workers |
| Total Transactions | 65,497 txs/min |
**Concurrency Scaling:**
| Workers | TPS |
|---------|-----|
| 1 | 438 |
| 5 | 1,094 (optimal) |
| 10 | 684 |
| 20 | 521 |
**Key Findings:**
- Single node achieves ~1,100 TPS sustained with optimal concurrency
- Higher concurrency (>5 workers) decreases TPS due to nonce contention
- Query latency is consistent at ~18ms
- Testnet mode uses K=20 Lux consensus (vs K=1 dev mode)
**Benchmark Command:**
```bash
cd ~/work/lux/benchmarks
LUX_ENDPOINT="http://localhost:9640/ext/bc/C/rpc" \
PRIVATE_KEY="<funded_key>" \
./bin/bench tps --chains=lux --duration=60s --concurrency=5
```

[![Build Status](https://github.com/luxfi/node/actions/workflows/ci.yml/badge.svg)](https://github.com/luxfi/node/actions)
[![Go Version](https://img.shields.io/badge/go-1.21.12-blue.svg)](https://golang.org/)
[![License](https://img.shields.io/badge/license-BSD--3--Clause-blue.svg)](LICENSE)
Node implementation for the [Lux](https://lux.network) network -
a blockchains platform with high throughput, and blazing fast transactions.
## Features
- **High Performance**: Optimized for throughput with sub-second finality
- **Multiple Consensus**: Support for Flare/Focus/Horizon/Quasar consensus protocols
- **EVM Compatible**: Full Ethereum Virtual Machine support on C-Chain
- **Multi-Chain Architecture**: Platform (P), Exchange (X), and Contract (C) chains
- **Custom Nets**: Create custom blockchain networks with configurable VMs
- **Cross-Chain Transfers**: Native cross-chain asset transfers between chains
- **L1 Validators**: Support for L1 (Layer 1) validator operations with BLS signatures
- **LP-118 Protocol**: Implementation of LP-118 for warp message handling and aggregation
## Installation
Lux is an incredibly lightweight protocol, so the minimum computer requirements are quite modest.
Note that as network usage increases, hardware requirements may change.
The minimum recommended hardware specification for nodes connected to Mainnet is:
- CPU: Equivalent of 8 AWS vCPU
- RAM: 16 GiB
- Storage: 1 TiB
- Nodes running for very long periods of time or nodes with custom configurations may observe higher storage requirements.
- OS: Ubuntu 22.04/24.04 or macOS >= 12
- Network: Reliable IPv4 or IPv6 network connection, with an open public port.
If you plan to build Lux Node from source, you will also need the following software:
- [Go](https://golang.org/doc/install) version >= 1.23.9
- [gcc](https://gcc.gnu.org/)
- g++
### Building From Source
#### Clone The Repository
Clone the Lux Node repository:
```sh
git clone git@github.com:luxfi/node.git
cd node
```
This will clone and checkout the `master` branch.
#### Building Lux Node
Build Lux Node by running the build task:
```sh
./scripts/run_task.sh build
```
The `node` binary is now in the `build` directory. To run:
```sh
./build/node
```
### Binary Install (GitHub Releases)
Download the [latest build](https://github.com/luxfi/node/releases/latest) for your operating system and architecture.
The Lux binary to be executed is named `luxd`.
#### Linux (amd64/arm64)
```sh
VERSION="vX.Y.Z"
GOARCH="amd64" # or arm64
curl -L -o node.tar.gz "https://github.com/luxfi/node/releases/download/${VERSION}/node-linux-${GOARCH}-${VERSION}.tar.gz"
tar -xzf node.tar.gz
./luxd --help
```
#### macOS (amd64/arm64)
```sh
VERSION="vX.Y.Z"
curl -L -o node.zip "https://github.com/luxfi/node/releases/download/${VERSION}/node-macos-${VERSION}.zip"
unzip node.zip
./luxd --help
```
### Docker Install
Make sure Docker is installed on the machine - so commands like `docker run` etc. are available.
Building the Docker image of latest `node` branch can be done by running:
```sh
./scripts/run-task.sh build-image
```
To check the built image, run:
```sh
docker image ls
```
The image should be tagged as `ghcr.io/luxfi/node:xxxxxxxx`, where `xxxxxxxx` is the shortened commit of the Lux source it was built from. To run the Lux node, run:
```sh
docker run -ti -p 9630:9630 -p 9631:9631 ghcr.io/luxfi/node:xxxxxxxx /node/build/node
```
## Running Lux
### Connecting to Mainnet
To connect to the Lux Mainnet, run:
```sh
./build/node
```
You should see some pretty ASCII art and log messages.
You can use `Ctrl+C` to kill the node.
### Connecting to Testnet
To connect to the Testnet, run:
```sh
./build/node --network-id=testnet
```
### Creating a Local Testnet
The [lux-cli](https://github.com/luxfi/lux-cli) is the easiest way to start a local network.
```sh
lux network start
lux network status
```
## Bootstrapping
A node needs to catch up to the latest network state before it can participate in consensus and serve API calls. This process (called bootstrapping) currently takes several days for a new node connected to Mainnet.
A node will not [report healthy](https://docs.lux.network/docs/api-reference/health-api) until it is done bootstrapping.
Improvements that reduce the amount of time it takes to bootstrap are under development.
The bottleneck during bootstrapping is typically database IO. Using a more powerful CPU or increasing the database IOPS on the computer running a node will decrease the amount of time bootstrapping takes.
## Generating Code
Lux Node uses multiple tools to generate efficient and boilerplate code.
### Running protobuf codegen
To regenerate the protobuf go code, run `scripts/run-task.sh generate-protobuf` from the root of the repo.
This should only be necessary when upgrading protobuf versions or modifying .proto definition files.
To use this script, you must have [buf](https://docs.buf.build/installation) (v1.31.0), protoc-gen-go (v1.33.0) and protoc-gen-go-grpc (v1.3.0) installed.
To install the buf dependencies:
```sh
go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.33.0
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.3.0
```
If you have not already, you may need to add `$GOPATH/bin` to your `$PATH`:
```sh
export PATH="$PATH:$(go env GOPATH)/bin"
```
If you extract buf to ~/software/buf/bin, the following should work:
```sh
export PATH=$PATH:~/software/buf/bin/:~/go/bin
go get google.golang.org/protobuf/cmd/protoc-gen-go
go get google.golang.org/protobuf/cmd/protoc-gen-go-grpc
scripts/run_task.sh generate-protobuf
```
For more information, refer to the [GRPC Golang Quick Start Guide](https://grpc.io/docs/languages/go/quickstart/).
### Running mock codegen
See [the Contributing document autogenerated mocks section](CONTRIBUTING.md####Autogenerated-mocks).
## Versioning
### Version Semantics
Lux Node is first and foremost a client for the Lux network. The versioning of Lux Node follows that of the Lux network.
- `v0.x.x` indicates a development network version.
- `v1.x.x` indicates a production network version.
- `vx.[Upgrade].x` indicates the number of network upgrades that have occurred.
- `vx.x.[Patch]` indicates the number of client upgrades that have occurred since the last network upgrade.
### Library Compatibility Guarantees
Because Lux Node's version denotes the network version, it is expected that interfaces exported by Lux Node's packages may change in `Patch` version updates.
### API Compatibility Guarantees
APIs exposed when running Lux Node will maintain backwards compatibility, unless the functionality is explicitly deprecated and announced when removed.
## Supported Platforms
Lux Node can run on different platforms, with different support tiers:
- **Tier 1**: Fully supported by the maintainers, guaranteed to pass all tests including e2e and stress tests.
- **Tier 2**: Passes all unit and integration tests but not necessarily e2e tests.
- **Tier 3**: Builds but lightly tested (or not), considered _experimental_.
- **Not supported**: May not build and not tested, considered _unsafe_. To be supported in the future.
The following table lists currently supported platforms and their corresponding
Lux Node support tiers:
| Architecture | Operating system | Support tier |
| :----------: | :--------------: | :-----------: |
| amd64 | Linux | 1 |
| arm64 | Linux | 2 |
| amd64 | Darwin | 2 |
| amd64 | Windows | Not supported |
| arm | Linux | Not supported |
| i386 | Linux | Not supported |
| arm64 | Darwin | Not supported |
To officially support a new platform, one must satisfy the following requirements:
| Lux Node continuous integration | Tier 1 | Tier 2 | Tier 3 |
| ---------------------------------- | :-----: | :-----: | :-----: |
| Build passes | &check; | &check; | &check; |
| Unit and integration tests pass | &check; | &check; | |
| End-to-end and stress tests pass | &check; | | |

### Consensus Transport
- ZAP binary wire protocol (`papers/lux-zap-wire-protocol.tex`) for consensus messages.
- Zero-allocation serialization path -- no GC pressure under load.
- Warp messaging for cross-chain: BLS aggregate signatures verified on-chain (`papers/lux-warp-messaging.tex`).
### Validator Security
- Zero-trust validator architecture (`papers/lux-zero-trust-validators.tex`).
- HSM boundary design for validator keys (`papers/lux-hsm-boundary.tex`).
- Hybrid certificate chains with PQ trust anchors (`papers/lux-hybrid-certificates.tex`).
- Reproducible builds with content-addressed attestation (`papers/lux-reproducible-builds.tex`).
## Key Management
### Validator Keys
- BLS signing keys stored in HSM (PKCS#11) or secure enclave where available.
- Threshold key generation via DKG -- no single party holds the full key.
- Key rotation via live secret resharing (LSS protocol) without chain downtime.
### HD Wallets
- BIP-32/44 hierarchical deterministic derivation.
- secp256k1 and secp256r1 key paths.
- Hardware wallet integration (Ledger, Trezor) for end-user keys.
### MPC Custody (M-Chain)
- FROST t-of-n for Schnorr/Taproot custody.
- CGGMP21 t-of-n for ECDSA custody (Ethereum, Bitcoin legacy).
- Session lifecycle management with NATS transport.
- Formal proofs: `papers/proofs/proof-crypto-frost.tex`, `papers/proofs/proof-crypto-cggmp21.tex`.
### Bridge Custody
- Teleport bridge uses MPC group keys -- no single custodian.
- Per-chain governance: each chain's bridge parameters are sovereign.
- Configurable key rotation delay.
- Formal proof: `papers/proofs/proof-bridge-teleport.tex`.
## Audit History
### Round 1 -- December 2025 (Component Audits)

| `audits/2025-12-30-warp-audit.md` | Warp cross-chain messaging |
| `audits/2025-12-30-zkvm-audit.md` | ZKVM (Z-Chain) |
Summary report: `security/2025-12-30-final-security-analysis.md`
Status report: `security/2025-12-30-FINAL-STATUS.md`
164 total findings (17 critical, 42 high, 58 medium, 47 low). Identified development placeholders (XOR stubs, length-only verification) in advanced features not yet in production. Core chains (P-Chain, X-Chain, C-Chain) passed clean.
### Round 3 -- January/March 2026 (Smart Contracts)
Two focused audits on the Solidity contract stack:
| Report | Scope |
|--------|-------|
| `audits/standard-2026-01-30/` | `@luxfi/standard` contract suite -- 832 tests, 105 fuzz tests |
| `audits/2026-03-25-comprehensive-security-audit.md` | `lux/standard` v1.6.5, `lux/liquid` v1.1.0, `liquidity/contracts` |
The March 2026 comprehensive audit used red/blue adversarial methodology with Foundry, Slither, Semgrep, Aderyn, Halmos (symbolic execution), and Lean 4 (theorem proving).
Results: 15 critical, 13 high, 10 medium, 3 low -- all remediated. 1,383 tests passing. 48 Halmos symbolic proofs + 33 Lean 4 theorems + 33 Foundry invariant tests.
Post-remediation risk: LOW. CI enforces Slither (fail-on: medium), Semgrep, Aderyn, and `forge fmt` on every push to main.
### Current Status
All critical and high findings from the contract audits are resolved. The December 2025 node audit identified development stubs in post-quantum and zero-knowledge subsystems that are not deployed to production; these are tracked and being replaced with real implementations as each subsystem matures.
## Formal Verification
50 mechanized proofs in `papers/proofs/`, covering:
- **Consensus**: safety, liveness, BFT thresholds, finality composition, validator economics
- **Cryptography**: BLS aggregation, FROST unforgeability, CGGMP21 UC-security, ML-DSA, ML-KEM, SLH-DSA, Corona, TFHE, CKKS, Verkle commitments, hybrid signatures, threshold composition, linear secret sharing
- **DeFi**: AMM invariants, order book correctness, flash loan safety, router correctness, governance, fee models
- **Bridge**: Teleport protocol, warp message security/delivery/ordering
- **Network**: peer discovery and eclipse resistance
- **Build**: reproducibility, attestation, coeffect algebra, cross-ecosystem verification
- **Trust**: authority lattice, vouch model, revocation
See `papers/INDEX.md` for the full list.
