Cryptographic Security for Electronic Transactions

US20160203477: Modernity Financial Holdings Ltd

Various embodiments include a wallet service that processes a cryptocurrency deposit into a cryptocurrency wallet account maintained in a wallet service system. The wallet service can receive an authentication parameter to authenticate the cryptocurrency deposit and record a transfer of a cryptocurrency amount from a first cryptocurrency address to a second cryptocurrency address. In response to and substantially immediately after authenticating the authentication parameter, the wallet service can exchange the cryptocurrency amount associated with the cryptocurrency deposit for fiat currency proceeds and deposit the fiat currency proceeds into a fiat reserve account. The wallet service can then associate exchangeable credit equal to the fiat currency proceeds to the cryptocurrency wallet account. In response to receiving a user-initiated request to spend a target portion of the exchangeable credit, the cryptocurrency wallet service can exchange, from the fiat reserve account, for cryptocurrency proceeds equal to the target portion.

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.
