20210359838 | BLOCKCHAIN TRANSACTION MANAGER - A blockchain transaction manager implements a method of managing submission of blockchain transactions to a node in a blockchain network by validating a received blockchain transaction and enqueuing the validated received blockchain transaction in a transaction queue, preparing at least one transaction attribute of the received blockchain transaction and placing the received blockchain transaction in a persistence queue, digitally signing or certifying the received blockchain transaction, attempting to submit the digitally signed or certified blockchain transaction to the node, and polling a blockchain status of the submitted blockchain transaction. Processes are provided for automatically recalculating blockchain transaction processing fees in the blockchain transaction attributes. Processes are also provided for repairing transaction attributes when the blockchain transaction has been rejected and submitting the repaired blockchain transaction to the node. Also, nonces are automatically assigned to received blockchain transactions and reassigned when the associated blockchain transaction has been rejected. | 2021-11-18 |
20210359839 | MULTI-BLOCKCHAIN DIGITAL TRANSACTION INFORMATION SEGREGATION SYSTEM - The systems and methods of the multi-blockchain transaction information segregation system of the present disclosure receive a first digital transaction, which includes first digital transaction information and second digital transaction information, through a network via broadcast by a first transaction device. A primary blockchain address provided on a primary blockchain is then identified in the first digital transaction, and a primary blockchain smart contract that is stored on the primary blockchain in association with the primary blockchain address is accessed. The primary blockchain smart contract is then executed to cause the first digital transaction information to be stored on the primary blockchain, and the second digital transaction information to be stored on a secondary blockchain that is separate from the primary blockchain. In a specific example, the first digital transaction information identifies a physical property, and the second digital transaction information identifies a purchase price of the physical property. | 2021-11-18 |
20210359840 | MANAGEMENT SYSTEM FOR ASSET DYNAMIC VALUE BASED ON BLOCKCHAIN AND METHOD THEREOF - A management system for asset dynamic value based on blockchain and a method thereof are disclosed. In the management system, an asset management host, an asset holding host and a transaction object host serving as nodes on a blockchain network are provided; the asset management host creates a smart contract associated with an asset to record statuses of funds, holdings and sub-assets; the asset holding host and the transaction object host are permitted to execute functions in the smart contract, so as to perform the transfer between the funds and the holdings and store the sub-assets in the smart contract. Therefore, the technical effect of improving convenience and credibility in dynamic management of asset value can be achieved. | 2021-11-18 |
20210359841 | DATA STORAGE, DATA CHECK, AND DATA LINKAGE METHOD AND APPARATUS - Methods, systems, and apparatus, including computer programs encoded on computer storage media, for data tracing are provided. One of the methods includes: receiving a data backtracking request, the data backtracking request comprising a version identifier of a first data version of a target object; obtaining, from the blockchain, version identifiers of a plurality of second data versions of the target object and a plurality of data blocks in the blockchain, wherein the second data versions comprise an initial data version of the target object, and at least one of the obtained data blocks comprises a version identifier of the initial data version; and determining, based on the version identifier of the initial data version, data content corresponding to the initial data version of the target object. | 2021-11-18 |
20210359842 | GUARANTEED ENCRYPTOR AUTHENTICITY - Embodiments described herein provide cryptographic techniques to enable a recipient of a signed message containing encrypted data to verify that the signer of the message and the encryptor of the encrypted data are the same party, or at the least, have joint possession of a common set of secret cryptographic material. These techniques can be used to harden an online payment system against interception and resigning of encrypted payment information. | 2021-11-18 |
20210359843 | THRESHOLD SCHEME ENABLED SYMMETRIC KEY MEMBER DELETION - A method of securing, by a managing node, communication in a network of member nodes including a first member node. Communication is secured using a (k, n | 2021-11-18 |
20210359844 | SYSTEM FOR EXCHANGING SYMMETRIC CRYPTOGRAPHIC KEYS USING COMPUTER NETWORK PORT KNOCKING - A system is provided for exchanging symmetric cryptographic keys using computer network port knocking. The system may receive, from a networked computing device, a first series of packets on a first series of ports which may signify a request to open a secure network connection. Once the secure network connection has been opened, the system may receive a second series of packets on a second series of ports which may be used as seed values to generate a symmetric cryptographic key. Finally, the system may then receive a third series of packets on a third series of ports which may signify the end of the second series of packets (e.g., the seed values). In this way, the system may exchange symmetric key values with the networked computing device which may then be used to open secure communication channels between the system and the computing device. | 2021-11-18 |
