Abstract: Abstract Business Process Management (BPM) systems are increasingly employed to automate and coordinate complex, multi-actor workflows across organizational boundaries. However, conventional cloud-based BPM solutions continue to face enduring challenges related to trust, data transparency, and auditability. This paper introduces a hybrid Cloud–Blockchain architecture that integrates the scalability and efficiency of cloud computing with the immutability and traceability of blockchain to enable secure and transparent BPM application composition. In the proposed model, large-scale process data and documents are securely processed and stored in the cloud, while metadata and cryptographic hashes are anchored on the blockchain to ensure integrity, authenticity, and verifiability. The architecture is structured into three core layers: (1) a BPM Orchestration layer responsible for coordinating workflow execution and managing cross-layer communication; (2) a Cloud Layer providing scalable computation and encrypted storage; and (3) a Blockchain Layer ensuring tamper-proof logging, smart contract–based validation, and trusted auditability. By combining cloud scalability with blockchain transparency, the architecture enhances BPM reliability and data integrity while minimizing reliance on centralized intermediaries. Future research will focus on implementing and evaluating the proposed model using Hyperledger Fabric and a BPM engine such as Camunda to assess performance, scalability, and security trade-offs in real-world scenarios.
