Smart contracts (blockchains, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to Wells Fargo Bank, the first patent addresses a quantum-safe blockchain vault system. Assigned to BCDB, the second patent addresses object oriented smart contracts for UTXO-based blockchains.
11695570, “Quantum-safe blockchain vault system,” assigned to Wells Fargo.
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 location external to the blockchain. In response to a request to protect data inside the block, the method further includes creating a security vault at the location, copying the block, and storing the copied block in the security vault using the pointer.
11694197, “Object oriented smart contracts for UTXO-based blockchains,” assigned to BCDB, Inc.
Disclosed is method and system for turning existing object-oriented programming languages into smart contract languages without introducing new syntactic features. The invented method and system provide a protocol that enables storing a history of computations on a decentralized computer network, such as UTXO-based blockchain system, for any object-oriented computer language. The invented method and system further provide for storing and updating data on blockchains, where such blockchains may be used in cryptocurrency applications and for smart contracts.
