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
- Security-First Design: Multi-layered key management with Shamir's Secret Sharing
- Distributed Authority: Clear separation between Admin (human oversight) and Leader (network operations)
- P2P Model Distribution: Bandwidth-efficient model replication across cluster
- DHT Business Storage: Configuration data stored in distributed hash table post-bootstrap
- Capability-Based Discovery: Nodes announce capabilities and auto-organize
Phase 1: Initial Node Setup & Key Generation
1.1 Bootstrap Machine Installation
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:
-
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
-
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
-
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

Phase 3: P2P Network Formation & Capability Discovery
3.1 P2P Network Bootstrap
Network Formation Process:
-
Bootstrap Node Configuration
- First installed node becomes bootstrap node
- Listens for P2P connections on configured port
- Maintains peer discovery registry
-
Peer Discovery via Announce Channel
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" -
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:
- Generate N shares of admin private key (N = peer count)
- Distribute one share to each peer via encrypted P2P channel
- Each peer stores share encrypted with their node-specific key
- 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:
- Each node calculates its fitness score
- Nodes broadcast their scores and capabilities
- Consensus algorithm determines leader (highest score + network agreement)
- Leader election occurs every 24 hours or on leader failure
- 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:
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:
- GPU Memory Threshold: Model must fit in available VRAM
- Redundancy: Minimum 3 copies across different nodes
- Geographic Distribution: Spread across network topology
- 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):
-
User Defines Custom Roles via web UI:
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"] -
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
-
Role Key Distribution:
- Store role key pairs in DHT with UCXL addresses
- Distribute to authorized users via secure channels
- Revocation handled through DHT updates
