New pending patent applications are published by the USPTO on Thursdays. Today's Spotlight Applications concern aspects of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Factom, the first application discloses techniques for smart contracts in blockchain environments. Assigned to EZBlock, Ltd , the second application
20200044857, "Smart contracts in blockchain environments," assigned to Factom, Inc.
Digital or "smart" contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular decision table and/or the digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the decision table and/or the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.
20200045019, "Blockchain joining for a limited processing capability device and device access security," assigned to EZBlock Ltd (KY)
A computer-implement method comprises: selecting a trusted computing node via smart contract on a blockchain; completing remote attestation of the selected trusted computing node; writing secret information to an enclave of the selected node; causing a thin device to establish a private connection with the selected node without revealing the secret information; and causing the selected node to act as a proxy on the blockchain for the device. Another method comprises: receiving a signed device access request from a device owner; validating, by the verification node, the received request; executing, by a verification node, a smart contract on a blockchain based on the received request; and producing, based on the executed smart contract, an output command to access the device for the device to validate, decrypt and execute.
