The architecture of the BC-SBOM is composed of 4 layers, each serving a distinct function within the system. The service layer provides essential services for registering SBOMs, querying dependency information, and propagating vulnerability alerts. The smart contract layer manages dependencies between software components and constructs a global view using smart contracts. The data repository layer stores and shares both SBOMs and DID documents. The blockchain network layer ensures the integrity and transparency of transactions in a decentralized manner.
