System and Method for Asset Rights Enforcement Using a Dual-Token Trust Architecture

Resumen de: US20260211982A1

0000 Systems and methods are disclosed for enforcing rights in an asset using a dual-token trust architecture. An asset to be held in trust is defined and stored in memory. A trustee token, representing custodial or fiduciary control of the asset, is generated and transferred to a trustee wallet address, with the transfer recorded on a blockchain. A beneficiary token is generated and transferred to a beneficiary wallet address distinct from the trustee wallet address. The beneficiary token functions as a cryptographic receipt evidencing one or more enforceable rights in the asset, while ownership or control of the asset remains with the trustee via the trustee token. The disclosed architecture separates asset custody from beneficiary rights and enables enforceable asset management across a wide range of asset types, including intellectual property rights, licenses, tickets or access credentials, digital currencies or stablecoins, and tokenized real-world assets.

Blockchain Architecture for Fiat-Denominated Smart Contract Execution via Oracle-Linked NAV

Resumen de: US20260212331A1

0000 A system and method are disclosed for executing fiat-denominated transactions using cryptocurrency coins fully collateralized by off-chain financial assets. The system calculates a dynamic Net Asset Value (NAV) by dividing the fair value of collateral assets, net of liabilities, by the number of outstanding coins. The NAV is periodically published to the blockchain via an oracle interface to ensure authenticity. All user interactions—purchases, redemptions, and transfers—are initiated through smart contracts that accept fiat-denominated inputs. Smart contracts retrieve the NAV from the blockchain and deterministically compute the required number of coins. This architecture performs all fiat-to-coin conversions on-chain through immutable contract logic, eliminating reliance on external systems. Authentication, balance verification, and ledger updates are enforced on-chain, with transaction events emitted for transparency. By embedding returns in the NAV and avoiding identity-based income distribution, the system enables technically robust, pseudonymous yield accrual compatible with decentralized blockchain infrastructure.
