Nutzergesteuertes Offline-Token-System mit TEEs

Resumen de: DE102025117723A1

Offenbart wird ein Verfahren zur Durchführung einer Transaktion mit einem digitalen Token oder einer digitalen Währung zwischen einer sendenden Partei und einer empfangenden Partei ohne bestehende Netzwerkverbindung. Zumindest die sendende Partei verfügt über eine vertrauenswürdige Ausführungsumgebung (TEE). Die TEE verfügt über eine vorbestimmte Anzahl von Stammzertifikaten, die von einer vertrauenswürdigen Partei signiert wurden und sowohl die Authentizität der TEE-Hardware als auch der auf der TEE laufenden Software attestieren. Die TEE verwaltet ein Blockchain-Konto, dessen privater Schlüssel ausschließlich in der TEE gespeichert ist. Der digitale Token oder die digitale Währung wurde vor der Transaktion auf das Blockchain-Konto der TEE übertragen. Die TEE bereitet die Transaktion vor und signiert sie. Die empfangende Partei führt eine erweiterte Fernattestierung durch, um die Authentizität der TEE der sendenden Partei und ihrer Software anhand lokal gespeicherter Informationen über die Stammzertifikate zu verifizieren. Nach erfolgreicher Fernattestierung überträgt die TEE der sendenden Partei die Transaktion an die empfangende Partei. Die empfangende Partei empfängt die Transaktion und speichert sie lokal so, dass entweder die sendende Partei oder die empfangende Partei die Transaktion zu einem späteren Zeitpunkt in der Blockchain registrieren kann. Der gesamte Offline-Transaktionsablauf wird von der TEE gesteuert. Alle beteiligten TEEs befolgen dass

METHODS AND DEVICES FOR PROPAGATING BLOCKS IN A BLOCKCHAIN NETWORK

Resumen de: EP4838834A2

0001 Methods and devices for propagating blocks in a blockchain network. At a mining node, while hashing a first block header of a first candidate block, the mining node sends, to other mining nodes, a first message specifying transactions and their order in a first ordered set of transactions contained in the first candidate block. The mining also receives a second message specifying transactions and their order in a second ordered set of transactions contained in a second candidate block being mined by a second mining node. If the mining node succeeds in mining the candidate block it notifies other mining nodes by providing them with a coinbase transaction, hash value, and timestamp. If another mining node is successful, then the mining node receives information from the other mining node from which, in conjunction with the second message, it can assemble the second candidate block and validate it.

HYBRID BLOCKCHAIN-BASED CONSENT MANAGEMENT

Resumen de: WO2026231158A1

A hybrid blockchain-based system for real-time, privacy-preserving consent management in a distributed node infrastructure creates immutable consent hashes that are stored on-chain for tamper-proof tracking, while encrypted sensitive data is stored off-chain. Smart contracts are used for dynamic consent control and automated enforcement; zero-knowledge proofs (ZKPs) to verify consent status without revealing personal information; decentralized identifiers (DIDs) for decentralized identity authentication; immutable blockchain records to create a tamper-proof, auditable consent history; and real-time propagation of consent changes across data partners. Unlike centralized systems, the invention in certain embodiments uses a distributed ledger to store immutable consent records. The decentralized nature of the ledger ensures that there is no single point of failure for the system, and enhances trust and transparency.

MUTABLE BLOCKCHAIN-BASED GENERAL LIABILITY TOKEN (GLT) SYSTEM WITH INTEGRATED STATISTICAL AND AI MONITORING FOR TAX COMPLIANCE AND SPECIALIZED IMPLEMENTATIONS FOR VAT INPUT CREDITS (VICT) AND GOVERNMENT TAX TOKEN (GTT)

Resumen de: WO2026229767A1

A blockchain-based framework for managing transferable obligations via digitally-encoded negative-value tokens. The system introduces the General Liability Token (GLT), whose balances are mutable, divisible, and aggregable within wallets to settle multiple obligations along upstream/downstream flows. Each wallet also maintains a non-transferable Unspendable Statistical Token (UST) updated per transaction; smart contracts read UST to recalibrate GLT balances and enforce dormancy and recovery (recursive liability tracing). An optional AI layer flags anomalous patterns for escalation. The framework supports implementations including VAT Input Credit Tokens (VICT) and Government Tax Tokens (GTT), enabling tokenized input-credit transfer and consumption-tax flows without reliance on cash refunds or centralized reconciliation. All lifecycle operations (issuance, split/merge, transfer, burning, dormancy, recovery) are executed on a permissioned blockchain, providing auditable, scalable, and fraud-resistant compliance infrastructure applicable beyond taxation to other obligation-management domains.

SYSTEMS AND METHODS FOR ON-CHAIN/OFF-CHAIN INTERACTIONS

Resumen de: US20260352487A1

The present technology includes systems and methods for low-latency, stateful interactions between two parties in a blockchain environment by shifting execution of application logic off-chain while preserving security and verifiability. An off-chain communication channel is established in association with an on-chain smart contract, allowing the parties to exchange a sequence of cryptographically authenticated state updates that collectively represent a current interaction state. A respective update is validated through coordinated cryptographic operations between the parties, forming a verifiable chain of state transitions. The disclosed approach reduces on-chain transaction overhead while maintaining trust, enabling applications such as interactive gaming, streaming services, and incremental payment systems.

Bitcoin-Anchor Authentication System with Spend-Triggered Revocation and Optional Hierarchical Delegation

Resumen de: US20260350229A1

A computer-implemented method, system, and non-transitory computer-readable medium for authentication and access control. A verifier generates a challenge message and receives a digital signature over the challenge message from an entity. The verifier recovers a Bitcoin public key and a corresponding Bitcoin address mathematically from the digital signature without the Bitcoin public key having been transmitted by the entity. The verifier determines an authentication anchor associated with the entity, the authentication anchor comprising a Bitcoin address or locking script or a designated unspent transaction output, and queries Bitcoin blockchain data to determine whether a revocation condition associated with the authentication anchor has occurred. Access is authorized only when the digital signature is valid and the authentication anchor is unrevoked. Embodiments include hierarchical delegation, multi-signature anchors, continuous session monitoring, and registry-based identification.

Resumen de: US20260352451A1

0000 A quantum-resistant system manages the key and model lifecycle of an artificial intelligence model within a trusted execution environment (TEE). A key management engine generates, seals, rotates, and revokes post-quantum keys bound to a hardware-rooted measurement. A secure model update module applies attested changes linking a prior state to a new state. A verifiable fine-tuning module binds, as a single signed unit, digests of training data, gradients, and resulting weights to the measurement. A tamper-evident provenance ledger records the operations and may anchor digests to a public blockchain. The system may mint a self-sovereign agent identity for consumption by a separate orchestration subsystem. Keys, updates, and evidence exist unencrypted only within the TEE and are tamper-evidently bound to the measurement, so an operator cannot alter or suppress them without invalidating the attestation.
