Interacts with Blockchain-SSM chaincode on Hyperledger Fabric, offering modules for direct API communication, CouchDB optimization, and complex query facilitation using a Signing State Machine approach.
Kotlin SDK for interacting with Blockchain-SSM (Signing State Machines) chaincode on Hyperledger Fabric.
// Spring Boot auto-configuration for chaincode operations

// Spring Boot auto-configuration for CouchDB queries
implementation("io.komune.c2:ssm-couchdb-spring-boot-starter:${Versions.c2}")
// Spring Boot auto-configuration for combined data queries

Communicates directly with the blockchain API for queries and transactions over Signing State Machines.
// Data models and query function definitions
implementation("io.komune.c2:ssm-chaincode-dsl:${Versions.c2}")
// F2 function implementations
implementation("io.komune.c2:ssm-chaincode-f2:${Versions.c2}")
Queries CouchDB attached to the blockchain to optimize costly requests (listing SSMs, sessions).
// Data models and query function definitions
implementation("io.komune.c2:ssm-couchdb-dsl:${Versions.c2}")
// F2 function implementations
implementation("io.komune.c2:ssm-couchdb-f2:${Versions.c2}")
Combines chaincode and CouchDB modules for complex queries.
// Data models and query function definitions
implementation("io.komune.c2:ssm-data-dsl:${Versions.c2}")
// F2 function implementations
implementation("io.komune.c2:ssm-data-f2:${Versions.c2}")
Transaction management for SSM operations.
// Data models
implementation("io.komune.c2:ssm-tx-dsl:${Versions.c2}")
// F2 function implementations
implementation("io.komune.c2:ssm-tx-f2:${Versions.c2}")
All F2 functions are implemented as Spring Beans for dependency injection.
make lint # Run detekt static analysis
make build # Build and publish to Maven local
make test # Run all tests (requires dev environment)
A pre-configured Hyperledger Fabric network is provided via Docker Compose:
make dev up # Start sandbox services
make dev down # Stop sandbox services
make dev logs # Follow service logs
Before running tests:
make test-pre # Pull images, start containers, configure /etc/hosts
Pre-configured Hyperledger Fabric Network with generated cryptographic materials and SSM chaincode installed. See c2-sandbox/README.md for details.
REST API gateway for blockchain operations. Builds as Docker image c2-chaincode-api-gateway.
