Digital currency mining circuitry having shared processing logic

US20160125040: 21 Inc.

An integrated circuit may be provided with cryptocurrency mining capabilities. The integrated circuit may include control circuitry and a number of processing cores that complete a Secure Hash Algorithm 256 (SHA-256) function in parallel. Logic circuitry may be shared between multiple processing cores. Each processing core may perform sequential rounds of cryptographic hashing operations based on a hash input and message word inputs. The control circuitry may control the processing cores to complete the SHA-256 function over different search spaces. The shared logic circuitry may perform a subset of the sequential rounds for multiple processing cores. If desired, the shared logic circuitry may generate message word inputs for some of the sequential rounds across multiple processing cores. By sharing logic circuitry across cores, chip area consumption and power efficiency may be improved relative to scenarios where the cores are formed using only dedicated logic.

System and method for analyzing transactions in a distributed ledger

US9298806:  Coinlab, Inc.

A system and method configured for analyzing transactions in a distributed ledger. The system may identify transactions where addresses and/or groupings of addresses are co-spent together and determine whether the addresses and/or groupings of addresses should be associated with each other. Addresses may be associated with each other in a grouping of addresses and/or potential grouping of addresses because they likely belong to the same entity. The system may identify different strengths and/or confidence levels of groupings of addresses and/or potential groupings of addresses. Strong groupings, relatively strong potential groupings, and/or other groupings of addresses, potential groupings of addresses, and/or groups may be grouped, associated, analyzed, and/or presented together. As such, the system may provide a comprehensive analysis of addresses associated with a given entity.

System and Method for Converting Cryptocurrency to Virtual Assets Whose Value is Substantiated by a Reserve of Assets

US20150332256: Bitreserve Ltd.

A computer-based system converts cryptocurrency into a virtual asset. The system includes a user account database server configured to store data of a plurality of user accounts. The stored data pertains to each user account and indicates an accounting of obligations of the system to the user. The system also includes a cryptocurrency account server configured to receive, from a networked device of a user, a transfer of crypto currency, from an external cryptocurrency account. In response to receipt of such a transfer, the cryptocurrency account server is configured to update the data pertaining to the obligations of the system to the user. The system also includes a user interface server configured to receive a request from the user for conversion of cryptocurrency to an asset. In response to receipt of the request, the system updates the data pertaining to the user account of the user.
