Assignee:  Inveniam Capital Partners (New York, NY) with total patents of: 45 (since 2005)
Counsel:  Firm: Koffsky Schwalb LLC
1st Invent:  Paul Snow (Austin, TX)
Inventors:  Genders: F=0, M=1
Abstract:
2000 char max
Hardware and software resources are load balanced when processing multiple blockchains. As more and more entities (whether public or private) are expected to generate their own blockchains for verification, a server or other resource in a blockchain environment may be over utilized. For example, as banks, websites, and retailers issue their own private cryptocoinage, the number of financial transactions may clog or hog networking and/or hardware resources. A blockchain load balancing mechanism thus allocates resources among the multiple blockchains.

Abstract:
2000 char max
A method executed by a computing device includes selecting a contingency-action token (CAT) of an object distributed ledger that meets minimum CAT requirements. The method further includes determining reassignment information for the selected CAT. The method further includes facilitating taking control of the selected CAT of a blockchain of the object distributed ledger using a securely passing process and updating the selected CAT utilizing the reassignment information for the CAT to produce an updated CAT. The method further includes causing generation of a new block affiliated with the updated CAT via the blockchain of the object distributed ledger using the securely passing process, where the new block includes the updated CAT.

Abstract:
2000 char max
A system for decentralized identification of a file access permission includes a front-end program and an access control server. The front-end program includes at least one credential. The front-end program extracts attribute data of a corresponding access condition and a definition file identifier (ID) of the credential from the credential based on a check rule message related to a specified file, to form a multi-credential proof file. The access control server obtains an issuer decentralized identifier (DID) and a first public key corresponding to the multi-credential proof file by querying a blockchain for all of the credential definition files corresponding to the multi-credential proof file, confirms that each piece of the attribute data in the multi-credential proof file is correct, and all of the attribute data in the multi-credential proof file meets the access condition, and then grants the front-end program an access permission corresponding to the specified file.
