Smart contracts, blockchains (distributed ledgers), and rights management broadly construed are the themes of today's Spotlight Patents. Both of today's Spotlight Patents are assigned to Wells Fargo Bank. The first patent addresses techniques for quantum entanglement authentication (QEA) / quantum consensus. The second patent addresses techniques for quantum-safe blockchain vault systems.
11,218,471, "Systems and methods for quantum consensus," assigned to Wells Fargo Bank.
Systems, apparatuses, and methods are disclosed for quantum entanglement authentication (QEA). An example method includes transmitting a first number and a second electronic identification of a second subset of the first set of entangled quantum particles to a second computing device, transmitting a second number and a first electronic identification of a first subset of a first set of entangled quantum particles to a first computing device, wherein each entangled quantum particle in the first set of entangled quantum particles is entangled with a respective entangled quantum particle in a second set of entangled quantum particles, receiving, from the first computing device, a first session key, receiving, from the second computing device, a second session key and in an instance in which the first session key corresponds to the second session key, authenticating a session between the first computing device and the second computing device.
11,212,110, "Quantum-safe blockchain vault system," assigned to Wells Fargo Bank.
Arrangements of the present disclosure relate to a method for securing data located in a blockchain having a plurality of blocks. The method includes creating a pointer within a block of the plurality of blocks, the pointer pointing to a security vault located external to the blockchain. The method further includes copying the block, storing the copied block in the security vault using the pointer, and securing the security vault.
