U.S. Patent 10796024 was awarded to Blockchain ASICs Inc. on October 06, 2020 and is entitled “Cryptographic ASIC for derivative key hierarchy.” The first named inventor is Edward L. Rodriguez De Castro of San Francisco, CA. The abstract contains an overview of the patent disclosure:

A cryptographic ASIC, method, and computer program product for creating, interacting with, and identifying an information stream via a derivative key hierarchy. A user with a programmed transform-enabled cryptographic circuit may process a predetermined input message to obtain a predetermined output message indicating an identity of a particular information stream, such as a blockchain. This user can also process other input messages, such as for verifying a blockchain, but cannot replicate the programmed transform-enabled cryptographic circuit without a transform key. At the medium level of the hierarchy, a user with the transform key can replicate the programmed transform-enabled cryptographic circuit, as well as process input messages and identify an information stream. However, only a user with knowledge of a user passphrase, from which the transform key may be derived during or after circuit manufacture, is capable of creating an information stream, such as a blockchain.
