Abstract—Financial enterprises increasingly face architectural decisions regarding the use of permissioned, consortium, public, or hybrid blockchain networks as digital assets, tokenized instruments, and distributed ledger technologies move from experimentation to production deployment. Much of the existing discourse frames blockchain adoption as a binary choice between private and public networks, overlooking the reality that financial use cases exhibit materially different requirements across privacy, governance, compliance, scalability, interoperability, and market access. This paper advances a use-case-driven architectural framework for blockchain adoption in financial enterprises, arguing that architecture selection should be determined by functional and regulatory requirements rather than ideological preferences for decentralization. Drawing on academic literature, industry research, and emerging regulatory guidance, the study comparatively examines permissioned, consortium, and public blockchain architectures within the context of core financial use cases, including enterprise resource planning integration, primary asset issuance, secondary market trading, and settlement. The analysis highlights how permissioned and consortium networks provide strong governance, confidentiality, and compliance alignment for internal operations and regulated issuance, while public blockchains offer liquidity, composability, and interoperability advantages for secondary markets and open settlement. The paper proposes a hybrid architectural reference model in which multiple blockchain network types coexist across the asset lifecycle, interconnected through interoperability layers and compliance-aware integration mechanisms. This approach reflects the evolving structure of financial market infrastructure and provides a practical foundation for scalable, compliant, and future-ready blockchain deployment in financial enterprises.
