Publication number: 20240113861Abstract: Technologies are shown for high granularity metric (HGM)-based control for smart contract execution. In accordance with some aspects, a function call associated with one or more methods of a smart contract on a blockchain is detected by identifying an entrance or exit of the function call in a kernel for smart contract execution on the blockchain. The function call is added to a function call stack, and one or more detected HGMs are identified in the function call stack. A comparison of the detected HGMs in the function call stack against one or more control rules is performed. Execution or completion of the function call is blocked based on the comparison.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Inventors: Venkata Siva Vijayendra BHAMIDIPATI, Michael CHAN, Derek CHAMORRO, Arpit JAIN, Ashok Srinivasa MURTHY

Patent number: 11899783Abstract: Technologies are shown for system level function based access control for smart contract execution on a blockchain. Access control rules control function calls at a system level by utilizing function boundary detection instrumentation in a kernel that executes smart contracts. The detection instrumentation generates a call stack that represents a chain of function calls in the kernel for execution of a smart contract. The access control rules are applied to the function call stack to allow or prohibit specific functions or function call chains. Access control rules can also define allowed or prohibited parameter data in the function call chain. If the function call chain or parameters do not meet the requirements defined in the access control rules, then the function call can be blocked from executing or completing execution. The access control rules can produce sophisticated access control policies based on complex function call chains.Type: GrantFiled: January 7, 2022Date of Patent: February 13, 2024Assignee: eBay, Inc.Inventors: Venkata Siva Vijayendra Bhamidipati, Michael Chan, Derek Chamorro, Arpit Jain, Ashok Srinivasa Murthy

Patent number: 11888966Abstract: Technologies are shown for HGM based control for smart contract execution. HGM control rules control function calls at a system level utilizing function boundary detection instrumentation in a kernel that executes smart contracts. The detection instrumentation generates a call stack that represents a chain of function calls in the kernel for a smart contract. The HGM control rules are applied to HGMs collected from the call stack to allow or prohibit specific HGMs observed in functions or function call chains. HGM control rules can use dynamic state data in the function call chain. If the dynamic state data observed in function call chains does not meet the requirements defined in the HGM control rules, then the function call can be blocked from executing or completing execution. The HGM control rules can be generated by executing known sets of acceptable or vulnerable smart contracts and collecting the resulting HGMs.Type: GrantFiled: June 27, 2022Date of Patent: January 30, 2024Assignee: eBay Inc.Inventors: Venkata Siva Vijayendra Bhamidipati, Michael Chan, Derek Chamorro, Arpit Jain, Ashok Srinivasa Murthy

Patent number: 11683169Abstract: Systems and methods for managing keys in a computer memory are described. In some embodiments, location addresses are determined for two key elements. A periodic time interval that is based on a time duration for performing a transaction involving a distance between the key elements is determined. One key element may be stored at a location address and then relocated to another location address after the periodic time interval has passed. In some embodiments, areas the computer memory may remain static during relocation of the key element.Type: GrantFiled: June 7, 2021Date of Patent: June 20, 2023Assignee: EBAY INC.Inventors: Michael J.

Patent number: 11676135Abstract: Technologies are shown for selecting a provider to service a client service request using a predictive metrics based consensus protocol to select a provider and create a service request transaction block to service the client service request. A client service request is received and forwarded to a set of providers. Proposed transactions are received from the providers and scored based on a predictive metric. A proposal transaction is selected based on the scoring and the selected transaction is written as a block on a service transaction blockchain. The provider for the selected transaction detects the block on the blockchain and performs the requested service. The client detects the block on the blockchain and transfers payment to the provider. Selection can be based on predictive metrics in the providers or macro metrics determined in miner nodes in combination with provider reputation, currency, load sharing, fairness, provisioning, and static and dynamic criteria.Type: GrantFiled: January 14, 2020Date of Patent: June 13, 2023Assignee: EBAY INC.Inventors: Venkata Siva Vijayendra Bhamidipati, Derek Chamorro, Michael Chan, Arpit Jain, Ashok Srinivasa Murthy, Anirudh Kamalapuram Muralidhar
