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.

0000 A system and method for accurate dividend distribution in investment products using proportional yield and temporal shifting. The disclosed system and method addresses challenges arising from real-time asset transfers and multi-day compounded rates. Specifically, the system calculates adjusted balances for investors by tracking ownership intervals across blockchain transactions, ensuring precise dividend distribution even during cross-chain transfers. It de-compounds multi-day rates provided by fund administrators into daily rates and schedules dividend payments accordingly, accounting for weekends, holidays, and other non-business days. By utilizing high-precision analytics and real-time synchronization between blockchains, the system ensures that dividend accruals are fair and accurate, even during asset transfers or when compounded rates span multiple days so that investors are paid equitably based on their actual holdings, regardless of transaction timing or cross-chain events.

0000 A method includes causing, based at least in part on a delta value, a cross-chain message comprising a transaction payload to be generated to perform a cross-chain operation from a source blockchain to a destination blockchain. The delta value is indicative of a difference between a total number of tokens having an attribution property in circulation of the source blockchain and a number of tokens having the attribution property in circulation of the source blockchain that are accounted for by one or more vaults of one or more primary blockchains. The attribution property identifies a token issuer. The method further includes causing the transaction payload to be applied to the destination blockchain to perform the cross-chain operation, wherein the cross-chain operation is performed with an associated space complexity that, based on use of the delta value for token reattribution, is sublinear with respect to a total number of token issuers.

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.

Resumen de: WO2026150235A1
This invention discloses a decentralized system and method for lottery and betting events using single-transaction participation on a distributed ledger network (e.g., a blockchain). Each participant merges payment and selections into a single on-chain record, either a Lottery Ticket Transaction (LTT) or a Betting Ticket Transaction (BTT), thereby reducing complexity. Outcomes can be determined on-chain via a random generator or off-chain via external oracles or AI-based processes, with authorized wallets submitting verified results. The system automatically allocates multi-tiered prizes and can be configured with fixed or dynamic pricing, bridging, token swapping, or fallback scenarios. A pseudonymous mechanism preserves user privacy while maintaining transparent, immutable records. By eliminating separate payment and selection steps, the invention streamlines lottery and wagering operations, supports cross-chain interoperability, and scales effectively for both large- and small-scale game businesses. Optional AI modules, compliance interfaces, and zero-knowledge proofs further enhance fairness, security, and adaptability across diverse commercial contexts.

Existing DAO governance systems operate entirely in software, allowing majority voters to execute proposals regardless of risk controls, enabling privileged actors to forge compliance logs, and forcing regulators to rely on unverifiable system reports. The present invention addresses these limitations by executing governance-critical logic within Trusted Execution Environments (TEEs), hardware-isolated processor regions inaccessible to operating systems, cloud providers, and blockchain nodes. The architecture introduces five elements: a Multi-TEE Quorum Verification Layer requiring agreement from three independent TEEs before authorization; an On-Chain Attestation Registry preventing counterfeit governance engines; a Regulatory Verification Network enabling independent compliance validation; a Post-Quantum Attestation Layer securing evidence for long-term retention; and Automated Treasury Safeguards including hardware-enforced freezes, circuit breakers, and insurance triggers. When violations are confirmed by quorum, cryptographic keys are destroyed, hardware counters advance, and network isolation activates, making non-compliant execution physically impossible while producing zero-knowledge proofs usable across multiple regulatory frameworks.
