  • Circuit and method for overcoming memory bottleneck of ASIC-resistant cryptographic algorithms
    Patent number: 11706020
    Abstract: An application-specific integrated circuit (ASIC) and method are provided for executing a memory-hard algorithm requiring reading generated data. A processor or state machine executes one or more steps of the memory-hard algorithm and requests the generated data. At least one specialized circuit is provided for generating the generated data on demand in response to a request for the generated data from the processor. Specific embodiments are applied to memory-hard cryptographic algorithms, including Ethash and Equihash.
    Type: Grant
    Filed: May 3, 2022
    Date of Patent: July 18, 2023
    Assignee: ePIC Blockchain Technologies Inc.
