PRIVATE SMART CONTRACT EVENTS IN A PERMISSIONED BLOCKCHAIN

Resumen de: WO2026030240A1

Herein is privacy for a smart contract that contains chaincode that sends chaincode events. In a configurable and backwards compatible way, broadcast of a chaincode event can be restricted. Before committing a transaction to a blockchain and without storing a newly generated private event into the transaction, the following are stored into the private event: an event payload, a hash of the payload and, unlike the state of the art, an identifier of a subscriber or organization that can receive the private event. After committing the transaction is an asynchronous detection that the identifier of the subscriber is associated with the event and, responsively, the payload of the event is sent to the subscriber.

Secure Message Lifecycle Management Using Off-Chain Storage and Blockchain-Anchored Event Records

Resumen de: AU2026200240A1

Abstract A computer-implemented method for managing secure message content is described. Message content associated with a message is received and stored in an off-chain content store. A payload identifier is generated that uniquely identifies the content independently of its physical storage location, and a first cryptographic hash of the stored content is computed. An off-chain mapping store holds a mapping record keyed by the payload identifier, including location data for retrieving the content and the first hash. A message event item including the payload identifier, the first hash and message lifecycle data is serialised into a canonical representation, hashed to obtain an event hash, and immutably anchored on a blockchain. Upon a subsequent access request, the associated message event item is re- serialised and verified against the blockchain event hash before the payload identifier is used to locate and retrieve the content. A third hash of the retrieved content is compared with the first hash to decide whether to release or withhold the content. Abstract an b s t r a c t a n g o C) an a n : o

DETECTING BATCHED TRANSACTIONS

Resumen de: EP4687089A1

A computer implemented method to obtain a batch transaction detection model that uses a machine learning process to detect that a transaction of a digital currency is a batch transaction is described. The method comprises obtaining transaction data from a block in a blockchain, wherein the transaction data comprises a plurality of items, each item having a set of features and associated feature values. The method further comprises generating an aggregated transaction data set of the transaction data and labelling the aggregated transaction data set according to whether the transaction is a batch transaction.

The redundant features are features determined not to be predictive for detecting batch transactions and wherein collinear features are features determined to be highly correlated with each other. The method then trains, tests and validates the batch transaction detection model using the reduced transaction data set; where the trained batch transaction detection model is adapted to determine whether a transaction is a batch transaction on the basis of the values of the features determined to be relevant to batch transaction detection.

Blockchain Records with Third Party Digital Signatures as an Enhanced Trust Element

Resumen de: US20260031994A1

A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.
