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.

DISTRIBUTED STORAGE AND AUTHENTICATION SYSTEM

Resumen de: WO2026030594A1

An authorized computing device receives indications of data actions taken end users on a user platform. Each data action is selected from a group comprising an edit action, a create action, or a delete action. The authorized computing device collects the data actions to form a batch of data actions. The batch of data actions include data actions that have occurred within a range of time. The authorized computing device generates a Merkle tree corresponding to the batch of data actions. Each leaf of the Merkle tree is associated with a respective data action in the batch of data actions. The authorized computing device published a root node of the Merkle tree to a smart contract associated with the user platform on a blockchain. The root node of the Merkle tree is used to verify individual data actions in the batch of data actions.

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 method then uses a feature selection method to remove from the aggregated transaction data redundant features and collinear features, in order to generate a reduced transaction data set having substantially independent features relevant to batch transaction detection. 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.

TRACING FLOW OF TAGGED FUNDS ON A BLOCKCHAIN

Resumen de: US20260030633A1

A system for “tagging” funds identified on a blockchain and associating a weight value therewith. The tagging profile is developed into a propagation profile wherein weight values are inherited from the tagging profile s.

ZELUS WALLET LLC [US]
Zelus Wallet, LLC

Resumen de: US20260030616A1

A user operating an endpoint app chooses to obtain a blockchain-based asset on a target blockchain. The user does not have blockchain transaction credentials for the target blockchain, but does have blockchain transaction credentials for a source blockchain. The endpoint app hierarchically creates target blockchain transaction credentials for the user, using an initial seed of entropy that was used to create the user's source blockchain transaction credentials. A backend component automatically obtains an amount of target blockchain cryptocurrency sufficient to obtain the blockchain-based asset on the target blockchain, in exchange for source blockchain cryptocurrency of the user. The obtained target blockchain cryptocurrency and the hierarchically created target blockchain transaction credentials are used to automatically obtain the blockchain-based asset on the target blockchain, such that once the transaction is completed, the obtained blockchain-based asset is registered to the address of the user's hierarchically created target blockchain transaction credentials.
