DECENTRALIZED AND SCALABLE STATE MANAGEMENT

Resumen de: EP4757240A2

This disclosure enhances a resilient high-bandwidth state-transition computer by incorporating a novel decentralized platform. The decentralized platform introduces a hierarchical, multi-level architecture utilizing node-sets and validation clusters to achieve exceptional scalability, fault tolerance, and data integrity. Entities, comprising distinct data sets, are distributed across node-sets, each maintaining a blockchain to record state changes. Node-set-level Merkle trees provide efficient data verification within node-sets, while a global Merkle tree combines node-set states into a unified representation of the global state, verified through consensus among validation clusters. This multi-dimensional cryptographic linking, enhanced by inter-node-set activations, creates a robust and tamper-proof system capable of handling millions of entities and ensuring data consistency across a distributed network.

TAX-ADVANTAGED BUSINESS OWNERSHIP TRANSFER SYSTEM

Resumen de: US20260154755A1

0000 The present disclosure provides a method for facilitating a tax-advantaged business transaction with automated risk mitigation. A conditional sales agreement is generated between a government entity and a business entity of a business owner. A net-revenue bond with interest obligations is structured. Payments from business operations are processed through automated withholding calculations. A distribution of funds to the business owner and the government entity is structured based on tax savings. Geographic information system data indicating location-based hazards affecting the business entity is received and correlated with business performance metrics to generate composite risk scores, which are used to automatically adjust payment processing and fund distribution. Exit procedures are triggered when the composite risk scores exceed predetermined thresholds. Blockchain-based smart contracts that automatically execute terms of the conditional sales agreement are implemented. Smart contract oracles are utilized to integrate real-time geographic information system data and payment information.

MEMORY-EFFICIENT CRYPTOGRAPHIC COMPUTATIONS IN SECURE COMMUNICATIONS

Resumen de: WO2026117674A1

A computer-implemented method enhances the efficiency and security of cryptographic tasks for modular exponentiation, digital signatures, key generation, and blockchain transaction verification. The method includes receiving a cryptographic task, retrieving a set of operands from memory, decomposing them into smaller parameters to construct multiple cryptographic sub- tasks, allocating non-overlapping memory regions for each sub-task and processes them in parallel. For each sub-task, a pair of variables is initiated in memory, followed by a bit-by-bit iteration through one of the parameters. During this iteration, the variables are updated based on each bit value. Once the iteration is complete, the value of the first variable is stored as an intermediate result in the corresponding memory region. Upon completing all parallel sub-tasks, the device aggregates the intermediate results to produce the final output of the cryptographic task, which is then used to generate verification data for secure communication.

SYSTEM AND METHOD FOR PROPORTIONAL INTEREST DISTRIBUTION IN FIXED-INCOME SECURITIES

Resumen de: WO2026115422A1

A modular computer system allocates income payments for financial instruments based on the precise duration of investor ownership. An ownership ledger stores records for digital fractional ownership units, including investor identifiers and time-stamped ownership intervals. An allocation engine retrieves ownership data and income payment information from a custodial entity, calculates an income amount per fractional unit using a fractionalization factor, determines time-weighted proportional income amounts for units held during a payment period, and aggregates the results to obtain total income per investor. The engine generates structured, machine-readable payment instructions identifying the instrument, investor account, payment period, and computed amount, and transmits the instructions to a disbursement system that updates internal ledgers and electronically distributes payments. The system supports fixed and variable interest rate transactions, off-exchange trades, and centralized or blockchain-based ownership records.

DISTRIBUTED COMPUTING SYSTEM WITH TOKEN-BASED SELECTION FREQUENCY CONTROL INDEPENDENT OF CONSENSUS WEIGHT

Resumen de: WO2026117638A1

A distributed computing system implements consensus where token holdings determine node selection frequency but not voting weight. Unlike proof-of-stake systems coupling stake with power, all selected nodes receive equal consensus voting weight regardless of tokens held (zero to millions). The system may employ multi-bucket partitioning preventing plutocratic control by dividing nodes based on aggregate stake thresholds. Zero-token nodes can participate and earn rewards. Transaction fees may be eliminated through staking-for-throughput allocation where tokens provide bandwidth rights. Applications may define custom consensus rules while base layer maintains voting equality. Operating on consumer hardware without specialized equipment, the system decouples economic incentive from political power, solving blockchain plutocracy while enabling true decentralization without capital barriers. An index token mechanism may link base token value to aggregate application activity.
