COMPUTER IMPLEMENTED METHODS AND SYSTEMS FOR PUBLIC KEY INFRASTRUCTURE AND IDENTITY VERIFICATION

Resumen de: US20260342541A1

Embodiments provide secure and flexible technical solutions for the verification of a user's identity, the creation of a web of trust, and/or the implementation of a PKI or Web of Trust. Some embodiments may be particularly suited for use in conjunction with a blockchain. The disclosure enables a validating entity to apply their own rules, policies and criteria for selection and/or combination of identity resources e.g. documents from a set of such resources that have been made available by a user. Thus, the user has control over which documents are made available to the validating entity, while the validating entity is able to select which, how many, and what type of resources it deems acceptable in order to successfully establish the user's identity. Access to a resource controlled by the validating entity is granted or denied as a result of the attempt to validate that the user is who they say they are based upon the resources they have provided.

Additional mechanisms enable other players to challenge pending zones or override owned zones through predefined conditions during time-bound challenge periods. Staking transactions and ownership transfers are recorded on a blockchain ledger 108, enabling secure and verifiable management of virtual territory ownership.

HARDWARE-ANCHORED POLICY-GOVERNED ARTIFICIAL INTELLIGENCE CODE GOVERNANCE SYSTEM

Resumen de: US20260342590A1

A hardware-anchored system generates software code by an artificial intelligence model executing within a trusted execution environment (TEE). A cryptographic attestation module binds, as a single signed structure, a hardware-rooted measurement of the TEE, a model identifier, and the inputs to the generated code. Validation agents independently evaluate the code; a consensus engine produces a decision; and a policy enforcement engine determines acceptance against machine-readable constraints. A tamper-resistant provenance ledger records the inputs, code, attestation evidence, validation outputs, decision, and acceptance, and may anchor digests to a public blockchain. A deployment orchestrator deploys conditional on acceptance. The code, attestation evidence, and decision 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.

SYSTEM AND METHOD FOR EXECUTION-DEPENDENT CONTROL OF TRANSACTION PROCESSING USING BLOCKCHAIN-BASED CREDENTIAL TOKENS

Resumen de: WO2026222511A1

Systems and methods are disclosed for execution-dependent control of transaction processing in a distributed ledger environment. A smart contract deployed on a blockchain network maintains on- chain state variables associated with a non-transferable credential token bound to an entity. Transaction execution logic invokes a verifier at transaction initiation to evaluate a lifecycle and validity status of the credential token based on the on-chain state variables. When the credential token is in an invalid state, execution of a transaction request fails closed and is rejected prior to commitment to the distributed ledger, preventing any resulting state change. Transaction execution is permitted only when the credential token is in a valid state. By coupling credential evaluation inseparably to transaction execution, the disclosed systems modify execution behavior of the distributed ledger to deterministically constrain transaction processing without reliance on off-chain validation or post-execution review.

Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain. The multi-party computation system configures the computer nodes configured to manage the first shard chain to perform the transaction validation process according to the multi-party computation scheme.
