Integration Philosophy

Anya Core follows a modular, secure, and standards-compliant integration approach:

Core Principles

  1. BIP Compliance: All Bitcoin integrations follow official Bitcoin Improvement Proposals
  2. Web5 Standards: Full compatibility with Web5 specifications and protocols
  3. ML Interoperability: Support for ONNX, TensorFlow, PyTorch, and custom models
  4. Security First: Defense-in-depth with multiple security layers
  5. Performance Optimized: Async-first architecture with efficient resource usage
  6. Developer Friendly: Comprehensive APIs with clear documentation

Design Patterns

// Standard integration pattern
pub trait Integration {
    type Config: Configuration;
    type Error: std::error::Error;

    async fn initialize(config: Self::Config) -> Result<Self, Self::Error>;
    async fn health_check(&self) -> Result<HealthStatus, Self::Error>;
    async fn shutdown(&mut self) -> Result<(), Self::Error>;
}

// Event-driven integration
pub trait EventHandler<T> {
    async fn handle_event(&self, event: T) -> Result<(), Self::Error>;
}

// Resource management
pub trait ResourceManager {
    async fn acquire_resource(&self) -> Result<Resource, Self::Error>;
    async fn release_resource(&self, resource: Resource) -> Result<(), Self::Error>;
}

Integration Types

1. Core System Integration

Direct integration with Anya Core's internal systems:

  • Extension API: Native Rust extensions with full system access
  • Plugin System: Sandboxed plugins with controlled access
  • Event System: Publish/subscribe event handling
  • Resource Management: Shared resource pools and lifecycle management

2. Blockchain Integration

Core Integration Architecture

Extension System Architecture

use anya_core::{Extension, Context, ExtensionResult};

#[async_trait]
pub trait Extension: Send + Sync {
    // Basic extension metadata
    fn name(&self) -> &str;
    fn version(&self) -> &str;
    fn description(&self) -> Option<&str> { None }

    // Lifecycle management
    async fn initialize(&mut self, ctx: &Context) -> ExtensionResult<()>;
    async fn shutdown(&mut self) -> ExtensionResult<()> { Ok(()) }

    // Health and monitoring
    async fn health_check(&self) -> ExtensionResult<HealthStatus>;
    async fn metrics(&self) -> ExtensionResult<Metrics> { Ok(Metrics::default()) }

    // Event handling
    async fn handle_event(&self, event: Event) -> ExtensionResult<()> { Ok(()) }

    // Configuration management
    fn config_schema(&self) -> Option<ConfigSchema> { None }
    async fn update_config(&mut self, config: Config) -> ExtensionResult<()> { Ok(()) }
}

Context and Dependency Injection

// Context provides access to core services
pub struct Context {
    bitcoin: Arc<BitcoinService>,
    web5: Arc<Web5Service>,
    ml: Arc<MLService>,
    storage: Arc<StorageService>,
    event_bus: Arc<EventBus>,
    config: Arc<Config>,
}

impl Context {
    // Service access
    pub fn bitcoin(&self) -> &BitcoinService { &self.bitcoin }
    pub fn web5(&self) -> &Web5Service { &self.web5 }
    pub fn ml(&self) -> &MLService { &self.ml }

    // Resource management
    pub async fn acquire_lock(&self, resource: &str) -> Result<ResourceLock, Error>;
    pub async fn get_storage(&self, namespace: &str) -> Result<Storage, Error>;

    // Event system
    pub async fn publish_event(&self, event: Event) -> Result<(), Error>;
    pub async fn subscribe<T>(&self, handler: impl EventHandler<T>) -> Result<Subscription, Error>;

    // Configuration
    pub fn config(&self) -> &Config { &self.config }
    pub async fn get_secret(&self, key: &str) -> Result<String, Error>;
}

// Define permissions and roles
let bitcoin_read = Permission::new("bitcoin.read");
let bitcoin_write = Permission::new("bitcoin.write");
let admin_role = Role::new("admin").with_permissions(vec![bitcoin_read, bitcoin_write]);

// Security context
let security_context = SecurityContext::new(user_id, vec![admin_role]);

// Authorization check
if security_context.has_permission(&bitcoin_write) {
    // Allow operation
    Ok(())
} else {
    Err(SecurityError::InsufficientPermissions)
}

Encryption and Key Management

use anya_security::{EncryptionManager, KeyManager, EncryptionAlgorithm};

// Key management
let key_manager = KeyManager::new(KeyConfig {
    key_store_type: KeyStoreType::Hardware,

    sensitive_data,
    EncryptionContext {
        key_id: "user_data_key".to_string(),
        additional_data: Some(user_id.as_bytes()),
    }
).await?;

let decrypted_data = encryption_manager.decrypt(
    encrypted_data,
    EncryptionContext {
        key_id: "user_data_key".to_string(),
        additional_data: Some(user_id.as_bytes()),
    }
).await?;

Secure Communication

use anya_security::{TlsConfig, CertificateManager};

// TLS configuration
let tls_config = TlsConfig {
    cert_file: "/etc/ssl/certs/anya.crt".into(),
    key_file: "/etc/ssl/private/anya.key".into(),
    ca_file: Some("/etc/ssl/certs/ca.crt".into()),

    auto_renewal: true,
    renewal_threshold: Duration::from_days(30),
    acme_provider: Some(AcmeProvider::LetsEncrypt),
});

cert_manager.ensure_valid_certificate().await?;

Testing Integration

Unit Testing

use anya_testing::{TestContext, MockBitcoinClient, MockWeb5Client};

#[tokio::test]
async fn test_bitcoin_integration() {
    let test_ctx = TestContext::new().await;
    let mock_bitcoin = MockBitcoinClient::new()
        .with_balance(bitcoin::Amount::from_btc(1.0).unwrap())
        .with_network(Network::Regtest);

    test_ctx.register_mock_service("bitcoin", Box::new(mock_bitcoin));

    let extension = MyExtension::new();
    extension.initialize(&test_ctx).await.unwrap();

    // Test extension functionality
    let result = extension.get_balance("test_wallet").await.unwrap();
    assert_eq!(result.as_btc(), 1.0);
}

Integration Testing

use anya_testing::{IntegrationTestSuite, TestNetwork};

#[tokio::test]
async fn test_full_integration() {
    let test_suite = IntegrationTestSuite::builder()
        .with_bitcoin_testnet()
        .with_web5_test_environment()
        .with_ml_test_models()
        .build()
        .await;

    // Test cross-system integration
    let transaction = test_suite.bitcoin()
        .create_transaction(recipient, amount)
        .await?;

    let credential = test_suite.web5()
        .create_transaction_credential(transaction)
        .await?;

    let classification = test_suite.ml()
        .classify_transaction(transaction)
        .await?;

    assert_eq!(classification.category, "payment");
    assert!(credential.verify().await?);
}

Best Practices

Performance Optimization

  1. Use async/await throughout: Never block the runtime
  2. Connection pooling: Reuse connections for external services
  3. Caching strategies: Implement appropriate caching layers
  4. Resource limits: Set proper limits for CPU, memory, and I/O

Error Handling

use anya_core::{AnyaError, ErrorKind};

// Proper error handling
#[derive(Debug, thiserror::Error)]
pub enum IntegrationError {
    #[error("Bitcoin RPC error: {0}")]
    BitcoinRpc(#[from] bitcoincore_rpc::Error),

    #[error("Web5 DID resolution failed: {0}")]
    DidResolution(String),

    #[error("ML model inference error: {0}")]
    MlInference(#[from] anya_ml::ModelError),

    #[error("Configuration error: {0}")]
    Configuration(String),
}

impl From<IntegrationError> for AnyaError {
    fn from(err: IntegrationError) -> Self {
        AnyaError::new(ErrorKind::Integration, err)
    }
}

Configuration Management

use anya_config::{Config, ConfigBuilder, Environment};

// Hierarchical configuration
let config = ConfigBuilder::new()
    .add_source(File::with_name("config.toml"))
    .add_source(Environment::with_prefix("ANYA"))
    .add_source(CommandLine::new())
    .build()?;

// Type-safe configuration
#[derive(Deserialize)]
struct IntegrationConfig {
    bitcoin: BitcoinConfig,
    web5: Web5Config,
    ml: MLConfig,
    security: SecurityConfig,
}

let integration_config: IntegrationConfig = config.try_deserialize()?;

Monitoring and Observability

use anya_monitoring::{Metrics, Tracing, HealthCheck};

// Metrics collection
let metrics = Metrics::new()
    .with_prometheus_exporter()
    .with_custom_metrics(vec![
        Counter::new("bitcoin_transactions_total"),
        Histogram::new("web5_did_resolution_duration"),
        Gauge::new("ml_model_memory_usage"),
    ]);

// Distributed tracing
#[tracing::instrument(skip(self))]
async fn process_transaction(&self, tx: Transaction) -> Result<(), Error> {
    tracing::info!("Processing transaction: {}", tx.txid());

    let span = tracing::span!(Level::INFO, "validate_transaction");
    let _guard = span.enter();

    // Process transaction
    Ok(())
}

// Health checks
let health_check = HealthCheck::builder()
    .add_check("bitcoin_rpc", || {
        Box::pin(async {
            bitcoin_client.get_blockchain_info().await.is_ok()
        })
    })
    .add_check("web5_resolvers", || {
        Box::pin(async {
            web5_client.resolve_test_did().await.is_ok()
        })
    })
    .build();
