New pending patent applications are published by the USPTO on Thursdays. Both of this week's Spotlight Applications concern blockchain (distributed ledger, smart contracts) and digital rights management broadly construed. Both applications also concern semiconductors. Assigned to nChain, the first application discloses techniques for implementing logic gate functionality using a blockchain. Assigned to NXM, the second application discloses techniques for a blockchain identification system.

The invention presents a solution in which blockchain Transactions are created to implement the functionality of a logic gate. The invention may be implemented on the Bitcoin platform or an alternative blockchain platform. The transaction includes a locking script which comprises instructions selected so as to implement the functionality of a logic gate, such as the XOR gate. When the script is executed (because a second transaction is attempting to spend the output associated with the locking script) the inputs will be processed by the conditional instructions to provide an output of TRUE or FALSE. The inputs are pre-processed by one or more computing agents so that they are evaluated to TRUE or FASLE prior to being used as inputs to the script. The second transaction is transmitted to the blockchain network for validation and, if determined to be valid, it will be written to the blockchain. Validation of the second transaction can be interpreted as a TRUE output. Thus, the locking script of the first transaction provides the functionality of the desired logic gate. The invention provides numerous advantages and can be used in a wide variety of applications, such as for the implementation of control systems and unit.
20190141048, "Blockchain identification system," assigned to NXM Technologies Inc. (CA)
A computing device comprises a processor module executing software to conduct a transaction, a networking module enabling connections to a peer-to-peer network, and an ASIC coupled to the processor module and the networking module. The ASIC comprises a blockchain server, an encryption module, and a memory storing a distributed ledger. The ASIC performs a calculation of a memory block within a predetermined minimum time and a predetermined maximum time. The block is stored in the distributed ledger by the blockchain server and is transmitted to the peer-to-peer network by the networking module.
