## Architecture Integration
|
||||
|
||||
### MCP Integration Points
|
||||
|
||||
All consensus agents integrate with the MCP (Model Context Protocol) coordination system:
|
||||
|
||||
```javascript
|
||||
// Memory coordination for persistent state
|
||||
await this.mcpTools.memory_usage({
|
||||
action: 'store',
|
||||
key: 'consensus_state',
|
||||
value: JSON.stringify(consensusData),
|
||||
namespace: 'distributed_consensus'
|
||||
});
|
||||
|
||||
// Performance monitoring
|
||||
await this.mcpTools.metrics_collect({
|
||||
components: ['consensus_latency', 'throughput', 'fault_tolerance']
|
||||
});
|
||||
|
||||
// Task orchestration
|
||||
await this.mcpTools.task_orchestrate({
|
||||
task: 'consensus_round',
|
||||
strategy: 'parallel',
|
||||
priority: 'high'
|
||||
});
|
||||
```
|
||||
|
||||
### Swarm Coordination
|
||||
|
||||
Agents coordinate with the broader swarm infrastructure:
|
||||
|
||||
- **Node Discovery**: Integration with swarm node discovery mechanisms
|
||||
- **Health Monitoring**: Consensus participation in distributed health checks
|
||||
- **Load Balancing**: Dynamic load distribution across consensus participants
|
||||
- **Fault Recovery**: Coordinated recovery from node and network failures
|
||||
|
||||
## Usage Patterns
|
||||
|
||||
### Basic Consensus Setup
|
||||
|
||||
```javascript
|
||||
// Initialize Byzantine consensus for high-security scenarios
|
||||
const byzantineConsensus = new ByzantineConsensusCoordinator('node-1', 7, 2);
|
||||
await byzantineConsensus.initializeNode();
|
||||
|
||||
// Initialize Raft for leader-based coordination
|
||||
const raftConsensus = new RaftConsensusManager('node-1', ['node-1', 'node-2', 'node-3']);
|
||||
await raftConsensus.initialize();
|
||||
|
||||
// Initialize Gossip for scalable information dissemination
|
||||
const gossipCoordinator = new GossipProtocolCoordinator('node-1', ['seed-1', 'seed-2']);
|
||||
await gossipCoordinator.initialize();
|
||||
```
|
||||
|
||||
### Security-Enhanced Consensus
|
||||
|
||||
```javascript
|
||||
// Add security layer to consensus protocols
|
||||
const securityManager = new SecurityManager();
|
||||
await securityManager.generateDistributedKeys(participants, threshold);
|
||||
|
||||
const secureConsensus = new SecureConsensusWrapper(
|
||||
byzantineConsensus,
|
||||
securityManager
|
||||
);
|
||||
```
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
```javascript
|
||||
// Benchmark and optimize consensus performance
|
||||
const benchmarker = new ConsensusPerformanceBenchmarker();
|
||||
const results = await benchmarker.runComprehensiveBenchmarks(
|
||||
['byzantine', 'raft', 'gossip'],
|
||||
scenarios
|
||||
);
|
||||
|
||||
// Apply adaptive optimizations
|
||||
const optimizer = new AdaptiveOptimizer();
|
||||
await optimizer.optimizeBasedOnResults(results);
|
||||
```
|
||||
|
||||
### State Synchronization
|
||||
|
||||
```javascript
|
||||
// Set up CRDT-based state synchronization
|
||||
const crdtSynchronizer = new CRDTSynchronizer('node-1', replicationGroup);
|
||||
const counter = crdtSynchronizer.registerCRDT('request_counter', 'G_COUNTER');
|
||||
const userSet = crdtSynchronizer.registerCRDT('active_users', 'OR_SET');
|
||||
|
||||
await crdtSynchronizer.synchronize();
