U.S. Patent 10447478 was awarded to Microsoft Technology Licensing, LLC on October 15, 2019 and is entitled “Cryptographic applications for a blockchain system.” The first named inventor is John Marley Gray of Snoqualmie, WA. The abstract contains an overview of the patent disclosure:

A method is provided for delegating behavior of a smart contract associated with a blockchain to code that is not part of the blockchain. A system directs execution by a virtual machine of the smart contract. During execution of the smart contract, the smart contract sends to a cryptlet container service, via a cryptodelegate, a request to delegate a behavior to a cryptlet that executes on an attested host. During execution the cryptlet container service identifies a host for executing code of the cryptlet in an appropriate cryptlet container. The cryptlet container service directs the identified host to execute the code of the cryptlet to perform the delegated behavior. After the delegated behavior is performed, the cryptlet container service receives from the cryptlet a response to the requested behavior. The cryptlet container service sends the response to the smart contract on the blockchain that is verified by the cryptodelegate. Link to Full Patent
