The method comprises: a client sending a first request message for acquiring an anonymous identifier to a server; when the first request message passes verification against a real user information table previously uploaded to a private blockchain, the server generating an anonymous identifier on the basis of a user authentication identifier, uploading anonymous user information comprising the anonymous identifier to an anonymous user information table of a consortium blockchain, and returning the anonymous identifier to the client; the client sending a second request message for acquiring an anonymous credential to a first management node; and when it is verified on the basis of the anonymous user information table that a user corresponding to the anonymous identifier has permission to access a target building device, the first management node generating an anonymous credential corresponding to the anonymous identifier, and returning the anonymous credential to the client.

ELEVATING OPTIMISTIC CONCURRENCY CONTROL IN PERMISSIONED BLOCKCHAINS WITH EXECUTE-ORDER-VALIDATE DESIGN PARADIGM

Resumen de: WO2025213464A1

A method for handling blockchain transaction where a client transmits a request to endorse a transaction with a special indication that such transaction should be batched with other transactions to one or more endorsing peers. Moreover, each endorsing peer simulates persisting the transaction invocation request to the ledger and, if the simulation is successful, adds an identifier for the transaction, TxID and invocation parameters to a WriteSet and sends a response to the client. In addition, the client sends an order request for the transaction to an ordering service for the inclusion of the transaction in a block, such as a gossip message received by each peer, which validates and commits the transaction. Moreover, a coordinator invokes a transaction that triggers the batch execution of a group of such pending transactions, such as all transactions of the batch are executed as one transaction representing the impact of all batched transactions.

Scalable Cluster Based Scoring with Multi-Queue Dynamic Scheduling Consensus Mechanism in Blockchain

Resumen de: US2025323805A1

Systems and methods are disclosed to revolutionize blockchain consensus mechanisms by introducing a novel, inclusive framework that enhances efficiency, scalability, and environmental sustainability. Central to this breakthrough are a cluster-based scoring system and a multi-queue dynamic scheduling mechanism, designed to replace resource-intensive consensus models like Proof of Work and Proof of Stake. This approach allows nodes to participate based on merit, determined through an iterative scoring process within clusters, democratizing access, and participation across the blockchain network. The system dynamically adjusts mining complexity as the blockchain evolves, ensuring scalability and reducing energy consumption. A key innovation is the introduction of cooldown periods to prevent dominance by any single node, promoting fairness and security. This decentralized, efficient, and scalable solution paves the way for broader blockchain adoption, maintaining the technology's foundational principles while addressing its traditional limitations.

DETERMINING A COMMON SECRET FOR THE SECURE EXCHANGE OF INFORMATION AND HIERARCHICAL, DETERMINISTIC CRYPTOGRAPHIC KEYS

Resumen de: EP4633082A1

A method (300) and system (1) of determining a common secret for two nodes (3, 7). Each node (3, 7) has a respective asymmetric cryptography pair, each pair including a master private key and a master public key. Respective second private and public keys may be determined based on the master private key, master public key and a deterministic key. A common secret may be determined at each of the nodes based on the second private and public keys. In one example, a node (3, 7) may determine the common secret based on (i) a second private key based on the node's own master private key and the deterministic key; and (ii) a second public key based on the other node's master public key and the deterministic key. The invention may be suited for use with, but not limited to, digital wallets, blockchain (e.g. Bitcoin) technologies and personal device security.

ELECTRONIC VOTING PLATFORM AND METHOD THEREOF

Resumen de: EP4632702A1

The present invention concerns the topic of electronic voting; that is, a voting method in which each voter can express his vote, even remotely, via an IT platform. This is a topic in which the interest is due to the fact that many electoral consultations represent quite complex events, because they mobilize a large number of people and must offer very high standards of security; consequently, they are significantly costly events.Electronic voting represents a way to reduce the costs of electoral consultations, to make them more efficient, and therefore also an instrument that can potentially be used more frequently. Moreover, an electoral consultation can be seen as a particular case of information management (a rather complex case, moreover) which, as such, should represent an almost natural, albeit challenging, field of application for information technologies.The proposed solution involves using at least a pair of servers configured to manage the voters and their votes separately, so as to allow, through an "Anonymous Kerberos" type approach, both the certain and reliable identification of the voters and the the anonymity of their vote: the latter is an essential guarantee to protect the freedom of voting.The voting platform indicated in the invention is configured to support a series of IT services combined in an original and complex way. In particular, the main state-of-the-art information technologies used by the invention concern encryption services as well as service
