The rapid adoption of Uncrewed Aerial Vehicles (UAVs) has driven aviation authorities to propose distributed Uncrewed Traffic Management (UTM) architectures. Several studies have advocated blockchain as a promising technology to meet these requirements. However, since UTM is a safety-critical and highly regulated domain, compliance with standards and regulatory frameworks is as crucial as performance and security. This work benchmarks two distributed architectures aligned with current regulatory frameworks: the Linux Foundation's InterUSS platform and a Hyperledger Fabric-based private ledger. Our findings reveal that blockchain-based systems require architectures specifically designed for aeronautical performance constraints.
