A method for creating and exchanging tokenized assets combines a dual ownership structure with a tiered exchange system. The method involves issuing membership non-fungible tokens to cooperative members, creating a tokenized asset through a legal entity and property ownership non-fungible token, and implementing a smart contract to generate property tokens representing fractional ownership. The exchange system for these property tokens implements sequential buying windows, providing initial exclusive access to non-token holders, followed by access to regional cooperative members, then global cooperative members, and finally institutional buyers. This approach may promote progressive decentralization of ownership while maintaining secure blockchain-based transfers within the cooperative framework. The method may enable fractional ownership of various assets, automated distribution of benefits, and a controlled secondary market structure that balances liquidity provision with ownership diversification.

A new approach is proposed to support hardware-based update of a software (e.g., a firmware) of an electronic device in a non-functional state. Under the proposed approach, the software is stored securely on a resource (e.g., a non-volatile storge) protected by a hardware-based lock mechanism. A first agent acquires a lock and authenticate the software. When a boot failure (e.g. authentication of the software fails) of the electronic device happens, an alert indicating the failure is generated and sent to a second agent (e.g., a sideband master) through an alert mechanism. The second agent then acquires a lock from the hardware-based lock mechanism to obtain exclusive excess to the resource and update the software stored in the non-volatile storage through, e.g., block write and / or read operations. The second agent then verifies that the software has been updated successfully so that the electronic device becomes functionally again.

Disclosed is a method for implementing a Zero Trust Architecture (ZTA) to secure network resources by eliminating lateral threat movement and minimizing attack surfaces. A zero trust policy engine, positioned inline between user devices and network resources, receives and evaluates access requests by verifying user and device identities along with context information. Based on dynamic risk scores derived from these evaluations, the engine enforces least-privileged, identity-based access policies, selectively granting access exclusively to authorized resources. Connections are terminated and re-established through secure proxy techniques, with continuous inspection of traffic for threats and data loss. Adaptive security measures, including isolation through pixel-streaming and context-aware access adjustments, further enhance protection. This architecture integrates seamlessly with cloud-based security service platforms, supporting workload-to-workload security, external entity integration, and comprehensive compliance reporting through audit trails and dashboards.
