# BZZZ Installation & Deployment Plan
## Architecture Overview
BZZZ employs a sophisticated distributed installation strategy that progresses through distinct phases: initial setup, SSH-based cluster deployment, P2P network formation, leader election, and finally DHT-based business configuration storage.
## Key Principles
1. **Security-First Design**: Multi-layered key management with Shamir's Secret Sharing
2. **Distributed Authority**: Clear separation between Admin (human oversight) and Leader (network operations)
3. **P2P Model Distribution**: Bandwidth-efficient model replication across cluster
4. **DHT Business Storage**: Configuration data stored in distributed hash table post-bootstrap
5. **Capability-Based Discovery**: Nodes announce capabilities and auto-organize
## Phase 1: Initial Node Setup & Key Generation
### 1.1 Bootstrap Machine Installation
```bash
curl -fsSL https://chorus.services/install.sh | sh
```
**Actions Performed:**
- System detection and validation
- BZZZ binary installation
- Docker and dependency setup
- Launch configuration web UI at `http://[node-ip]:8080/setup`
### 1.2 Master Key Generation & Display
**Key Generation Process:**
1. **Master Key Pair Generation**
- Generate RSA 4096-bit master key pair
- **CRITICAL**: Display private key ONCE in read-only format
- User must securely store master private key (not stored on system)
- Master public key stored locally for validation
2. **Admin Role Key Generation**
- Generate admin role RSA 4096-bit key pair
- Admin public key stored locally
- **Admin private key split using Shamir's Secret Sharing**
3. **Shamir's Secret Sharing Implementation**
- Split admin private key into N shares (where N = cluster size)
- Require K shares for reconstruction (K = ceiling(N/2) + 1)
- Distribute shares to BZZZ peers once network is established
- Ensures no single node failure compromises admin access
### 1.3 Web UI Security Display
```
┌─────────────────────────────────────────────────────────────────┐
│ 🔐 CRITICAL: Master Private Key - DISPLAY ONCE ONLY │
├─────────────────────────────────────────────────────────────────┤
│ │
│ -----BEGIN RSA PRIVATE KEY----- │
│ [MASTER_PRIVATE_KEY_CONTENT] │
│ -----END RSA PRIVATE KEY----- │
│ │
│ ⚠️ SECURITY NOTICE: │
│ • This key will NEVER be displayed again │
│ • Store in secure password manager immediately │
│ • Required for emergency cluster recovery │
│ • Loss of this key may require complete reinstallation │
│ │
│ [ ] I have securely stored the master private key │
│ │
└─────────────────────────────────────────────────────────────────┘
```
## Phase 2: Cluster Node Discovery & SSH Deployment
### 2.1 Manual IP Entry Interface
**Web UI Node Discovery:**
```
┌─────────────────────────────────────────────────────────────────┐
│ 🌐 Cluster Node Discovery │
├─────────────────────────────────────────────────────────────────┤
│ │
│ Enter IP addresses for cluster nodes (one per line): │
│ ┌─────────────────────────────────────────────────────────────┐ │
│ │ 192.168.1.101 │ │
│ │ 192.168.1.102 │ │
│ │ 192.168.1.103 │ │
│ │ 192.168.1.104 │ │
│ └─────────────────────────────────────────────────────────────┘ │
│ │
│ SSH Configuration: │
│ Username: [admin_user ] Port: [22 ] │
│ Password: [••••••••••••••] or Key: [Browse...] │
│ │
│ [ ] Test SSH Connectivity [Deploy to Cluster] │
│ │
└─────────────────────────────────────────────────────────────────┘
```
### 2.2 SSH-Based Remote Installation
**For Each Target Node:**
1. **SSH Connectivity Validation**
- Test SSH access with provided credentials
- Validate sudo privileges
- Check system compatibility
2. **Remote BZZZ Installation**
```bash
# Executed via SSH on each target node
ssh admin_user@192.168.1.101 "curl -fsSL https://chorus.services/install.sh | BZZZ_ROLE=worker sh"
```
3. **Configuration Transfer**
- Copy master public key to node
- Install BZZZ binaries and dependencies
- Configure systemd services
- Set initial network parameters (bootstrap node address)
4. **Service Initialization**
- Start BZZZ service in cluster-join mode
- Configure P2P network parameters
- Set announce channel subscription
## Phase 3: P2P Network Formation & Capability Discovery
### 3.1 P2P Network Bootstrap
**Network Formation Process:**
1. **Bootstrap Node Configuration**
- First installed node becomes bootstrap node
- Listens for P2P connections on configured port
- Maintains peer discovery registry
2. **Peer Discovery via Announce Channel**
```yaml
announce_message:
node_id: "node-192168001101-20250810"
capabilities:
- gpu_count: 4
- gpu_type: "nvidia"
- gpu_memory: [24576, 24576, 24576, 24576] # MB per GPU
- cpu_cores: 32
- memory_gb: 128
- storage_gb: 2048
- ollama_type: "parallama"
network_info:
ip_address: "192.168.1.101"
p2p_port: 8081
services:
- bzzz_go: 8080
- mcp_server: 3000
joined_at: "2025-08-10T16:22:20Z"
```
3. **Capability-Based Network Organization**
- Nodes self-organize based on announced capabilities
- GPU-enabled nodes form AI processing pools
- Storage nodes identified for DHT participation
- Network topology dynamically optimized
### 3.2 Shamir Share Distribution
**Once P2P Network Established:**
1. Generate N shares of admin private key (N = peer count)
2. Distribute one share to each peer via encrypted P2P channel
3. Each peer stores share encrypted with their node-specific key
4. Verify share distribution and reconstruction capability
## Phase 4: Leader Election & SLURP Responsibilities
### 4.1 Leader Election Algorithm
**Election Criteria (Weighted Scoring):**
- **Network Stability**: Uptime and connection quality (30%)
- **Hardware Resources**: CPU, Memory, Storage capacity (25%)
- **Network Position**: Connectivity to other peers (20%)
- **Geographic Distribution**: Network latency optimization (15%)
- **Load Capacity**: Current resource utilization (10%)
**Election Process:**
1. Each node calculates its fitness score
2. Nodes broadcast their scores and capabilities
3. Consensus algorithm determines leader (highest score + network agreement)
4. Leader election occurs every 24 hours or on leader failure
5. **Leader ≠ Admin**: Leader handles operations, Admin handles oversight
### 4.2 SLURP Responsibilities (Leader Node)
**SLURP = Service Layer Unified Resource Protocol**
**Leader Responsibilities:**
- **Resource Orchestration**: Task distribution across cluster
- **Model Distribution**: Coordinate ollama model replication
- **Load Balancing**: Distribute AI workloads optimally
- **Network Health**: Monitor peer connectivity and performance
- **DHT Coordination**: Manage distributed storage operations
**Leader Election Display:**
```

```
## Phase 5: Business Configuration & DHT Storage
### 5.1 DHT Bootstrap & Business Data Storage
**Only After Leader Election:**
- DHT network becomes available for business data storage
- Configuration data migrated from local storage to DHT
- Business decisions stored using UCXL addresses
**UCXL Address Format:**
```
ucxl://bzzz.cluster.config/network_topology
ucxl://bzzz.cluster.config/resource_allocation
ucxl://bzzz.cluster.config/ai_models
ucxl://bzzz.cluster.config/user_projects
```
### 5.2 Business Configuration Categories
**Stored in DHT (Post-Bootstrap):**
- Network topology and node roles
- Resource allocation policies
- AI model distribution strategies
- User project configurations
- Cost management settings
- Monitoring and alerting rules
**Kept Locally (Security/Bootstrap):**
- Admin user's public key
- Master public key for validation
- Initial IP candidate list
- Domain/DNS configuration
- Bootstrap node addresses
## Phase 6: Model Distribution & Synchronization
### 6.1 P2P Model Distribution Strategy
**Model Distribution Logic:**
```python
def distribute_model(model_info):
model_size = model_info.size_gb
model_vram_req = model_info.vram_requirement_gb
# Find eligible nodes
eligible_nodes = []
for node in cluster_nodes:
if node.available_vram_gb >= model_vram_req:
eligible_nodes.append(node)
# Distribute to all eligible nodes
for node in eligible_nodes:
if not node.has_model(model_info.id):
leader.schedule_model_transfer(
source=primary_model_node,
target=node,
model=model_info
)
```
**Distribution Priorities:**
1. **GPU Memory Threshold**: Model must fit in available VRAM
2. **Redundancy**: Minimum 3 copies across different nodes
3. **Geographic Distribution**: Spread across network topology
4. **Load Balancing**: Distribute based on current node utilization
### 6.2 Model Version Synchronization (TODO)
**Current Status**: Implementation pending
**Requirements:**
- Track model versions across all nodes
- Coordinate updates when new model versions released
- Handle rollback scenarios for failed updates
- Maintain consistency during network partitions
**TODO Items to Address:**
- [ ] Design version tracking mechanism
- [ ] Implement distributed consensus for updates
- [ ] Create rollback/recovery procedures
- [ ] Handle split-brain scenarios during updates
## Phase 7: Role-Based Key Generation
### 7.1 Dynamic Role Key Creation
**Using Admin Private Key (Post-Bootstrap):**
1. **User Defines Custom Roles** via web UI:
```yaml
roles:
- name: "data_scientist"
permissions: ["model_access", "job_submit", "resource_view"]
- name: "ml_engineer"
permissions: ["model_deploy", "cluster_config", "monitoring"]
- name: "project_manager"
permissions: ["user_management", "cost_monitoring", "reporting"]
```
2. **Admin Key Reconstruction**:
- Collect K shares from network peers
- Reconstruct admin private key temporarily in memory
- Generate role-specific key pairs
- Sign role public keys with admin private key
- Clear admin private key from memory
3. **Role Key Distribution**:
- Store role key pairs in DHT with UCXL addresses
- Distribute to authorized users via secure channels
- Revocation handled through DHT updates

- **Business Data**: Encrypted before DHT storage
- **Network Communication**: All P2P traffic encrypted
- **Key Recovery**: Master key required for emergency access
### Network Security
- **mTLS**: All inter-node communication secured
- **Certificate Rotation**: Automated cert renewal
- **Access Control**: Role-based permissions enforced
- **Audit Logging**: All privileged operations logged
## Monitoring & Observability
### Network Health Metrics
- P2P connection quality and latency
- DHT data consistency and replication
- Model distribution status and synchronization
- Leader election frequency and stability
### Business Metrics
- Resource utilization across cluster
- Cost tracking and budget adherence
- AI workload distribution and performance
- User activity and access patterns
## Failure Recovery Procedures
### Leader Failure
1. Automatic re-election triggered
2. New leader assumes SLURP responsibilities
3. DHT operations continue uninterrupted
4. Model distribution resumes under new leader
### Network Partition
1. Majority partition continues operations
2. Minority partitions enter read-only mode
3. Automatic healing when connectivity restored
4. Conflict resolution via timestamp ordering
### Admin Key Recovery
1. Master private key required for recovery
2. Generate new admin key pair if needed
3. Re-split and redistribute Shamir shares
4. Update role signatures with new admin key
This plan provides a comprehensive, security-focused approach to BZZZ cluster deployment with clear separation of concerns and robust failure recovery mechanisms.
