Smart contracts, (blockchains, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to MSFT, the first patent addresses techniques for secure transactions using cryptlet smart contract. Assigned to IBM, the second patent addresses techniques for verification of conditions of a blockchain transaction.
11488121, “Cryptlet smart contract,” assigned to Microsoft.
The disclosed technology is generally directed to secure transactions. In one example of the technology, a smart contract is generated based at least in part on a schema and provided information. The smart contract may be caused to be deployed on a ledger as a smart contract ledger instance. A unique address associated with the deployed smart contract ledger instance may be received. A cryptlet binding for a first contract cryptlet that is associated with the smart contract ledger instance may be generated. The cryptlet binding may be sent to the first contract cryptlet. Responsive to a state change associated with the first contract cryptlet, an update may be communicated to the smart contract ledger instance.
11489672, “Verification of conditions of a blockchain transaction,” assigned to IBM.
An example operation may include one or more of connecting, by a multi-party smart contract server, to a blockchain network configured to store cryptographic proofs, generating, by the multi-party smart contract server, a proposed transaction, providing, by the multi-party smart contract server, the proposed transaction to a plurality of participant nodes, receiving, by the multi-party smart contract server, responses to the proposed transaction from the participant nodes, executing, by the multi-party smart contract server, a smart contract to request from respondent participant nodes attestations of required conditions of the smart contract, receiving and verifying, by the multi-party smart contract server, the attestations from the respondent participant nodes, and executing the proposed transaction and posting a cryptographic proof of a successful execution to the blockchain, by the multi-party smart contract server, in response to a satisfaction of the required conditions of the smart contract.
