METHOD AND SYSTEM FOR SECURING PERSONAL IDENTIFIABLE INFORMATION (PII) IN BLOCKCHAIN

Resumen de: US20260105183A1

Current approaches allow storage of Personal Identifiable Information (PII) data on blockchain, however the user will not be allowed to delete any data from blockchain because of data immutability. As a result, even if the user doesn't want the data to remain on the blockchain platform, there is no option to delete it. Method and system disclosed herein provides an approach, in which PII data is stored in a ledger by encrypting it using a salt and key. When the user doesn't want the data to be stored in the blockchain ledger, the system deletes, upon receiving a PII data deletion request from the user, the key and the salt stored in the off-chain system, wherein the deletion of the key and the salt ensures permanent inaccessibility of PII data from the secondary blockchain ledger.

DECENTRALIZED PRIVACY-PRESERVING REWARDS WITH CRYPTOGRAPHIC BLACK BOX ACCUMULATORS

Resumen de: US20260105493A1

A decentralized and trust-minimizing computer architecture for computing rewards for users of an advertising system includes cryptographic black box accumulators (BBA), which is a cryptographic counter that only the issuer can update. An attention application requests initialization of a BBA from a guardian and subsequently requests updates to the BBA to track interactions between a user of the attention application and ads on the attention application. The guardian signs updates to the BBA to reach agreement on the state of ad interactions. The attention application may randomize the BBA and submit requests via an anonymous channel such that no participant can link two encounters with the BBA to each other or link the BBA to a specific attention application, thus improving user privacy. Reward redemption requests can be made based on a known policy and committed to a public blockchain for verification by observers that the protocol is operating correctly.

SMART CONTRACT CALLING METHODS, EXECUTION METHODS, COMPUTER DEVICES, AND STORAGE MEDIA

Resumen de: US20260104870A1

Smart contract calling is described. A blockchain node receives a transaction that calls a contract.

Each process of executing the Wasm bytecode includes: starting a Wasm virtual machine instance, creating a linear memory corresponding to the instance based on the cached Wasm module object, and filling the linear memory. Code is executed in a code segment in the Wasm module object based on the filled linear memory and the input parameter.

DECOUPLING NATIVE AND NON-NATIVE TOKENS IN BLOCKCHAIN TRANSACTIONS INTRODUCTION

Resumen de: WO2024254572A1

Certain aspects of the present disclosure provide techniques and apparatus for efficiently processing transactions on a. blockchain. An example method generally includes receiving, at a relay service, a request to execute a transaction on a blockchain. Generally, the request includes a request to transfer a quantity of a. first type of token on the blockchain from a transmitter wallet to a receiver wallet identified in the request and incurs a transaction overhead on the blockchain in a. second type of token. The request is modified based on the quantity of the first type of token, the transaction overhead in the second type of token, and a policy defining a source from which the transaction overhead is to be retrieved. The transaction is executed on the blockchain based on the modified request without transferring the second type of token from the transmitter wallet to satisfy the transaction overhead.

Transaction System and Method

Resumen de: US20260099830A1

0000 The invention relates to systems and methods for executing a digital-asset transaction using a dual-tier messaging architecture. A central messaging server provides tamper detection and message-integrity verification while routing bilateral messages between transacting devices. A permissioned-blockchain channel manages a smart-contract escrow that holds digital assets in cold storage. A fiat-rail channel integrates a real-time payment protocol to obtain bank or rail confirmation that fiat funds are credited to a seller account. Upon receipt of settlement evidence and a validated session state, the escrow releases the digital asset from a seller cold-storage wallet to a buyer cold-storage wallet. Embodiments may capture a seller opt-in via a banking application, generate a dual-ledger audit trail across permissioned and public blockchains, and emit transaction identifiers for cross-system reconciliation. The approach improves compliance, reduces counterparty risk, and provides verifiable audit artifacts for regulated settlement of digital-asset transfers.
