Resumen de: WO2026039126A1
Systems and methods for securely accessing information pertaining to an upstream entity using a verifiable credential with an embedded distributed identifier includes generating an authorization request for access to the information by a downstream entity. The authorization request includes a decentralized identifier associated with the downstream entity and is transmitted to a content storage entity. An authorization notification corresponding to the authorization request is received. An authorization token is retrieved. The authorization token includes a verifiable credential generated by the upstream entity and incorporating the decentralized identifier. A request transaction including a request to access the information pertaining to the upstream entity and the authorization token is generated and transmitted to the content storage entity. A verification challenge corresponding to the request transaction based on the verifiable credential is received and a response is transmitted. A reply transaction is received granting access to the information pertaining to the upstream entity.

A computer-implemented method of processing a blockchain transaction request comprises receiving (2014; 3014; 4012) a blockchain transaction request and directing (2020; 3020; 4020) the blockchain transaction request to a specific node of a blockchain. The specific node interrupts (2030) execution of the blockchain transaction request, and directly or indirectly performs (2046) at least one service in relation to the blockchain transaction request.

This application provides a data management method, and the method includes: A client receives a backup plan configured by a user for to-be-backed-up data; the client divides the to-be-backed-up data into c data blocks based on a quantity of cloud nodes used for backup and a quantity of backup copies, and stores the c data blocks in n cloud nodes on multi-cloud platforms in a distributed manner, where for at least one data block in the c data blocks, the multi-cloud platforms store b backup copies of the at least one data block; and the client provides, for a blockchain network, metadata of the data stored on the multi-cloud platforms, so that the blockchain network encodes the metadata into a backup identifier, and stores the backup identifier, where the backup identifier is used to address the data stored on the multi-cloud platforms. In this method, cloud-chain convergence is performed with reference to features of the blockchain network of being decentralized, secure, and reliable, to improve security of multi-cloud backup data and eliminate a single-point security bottleneck in a conventional method.
Resumen de: CN120981828A
The blockchain system is capable of participating in distributed transactions using a two-stage commit protocol ("2PC"). In a 2PC, a computer system, such as a DBMS or blockchain system, submits transactions that change data (e.g., database, world state) using two stages. To participate in a distributed transaction using a 2PC, a blockchain system performs a "staged transaction". The staged transaction passes through a 2PC stage. In the preparation stage, the new value of the world state record is temporarily stored in the stage record as a stage value. In a second stage, if a distributed transaction is to be submitted, a world stage record is set to a stage value.

Methods are disclosed whereby a coordinating party generates a first blockchain transaction that is configured to verify that a second blockchain transaction supplied to the first transaction contains at least two data values, and consequently release an amount of a digital asset. The first data value is generated by a first party digitally signing a first message. Similarly, the second data value is generated by a second party digitally signing a second message. The second party must have knowledge of both the first and second data values to generate the second transaction, with the first data value, along with a blockchain transaction template, sent by the first party to the second party. The method can be used as a VAT automation protocol, with VAT sent directly to HMRC
