PayPal blockchain transaction validation and storage patent
Summary
The USPTO granted Patent US12597026B2 to PayPal, Inc. on April 7, 2026. The patent covers a system and method for validating and storing blockchain transaction data using challenge-response authentication and cryptographic hash verification across linked data blocks. The patent, filed as Application No. 18596060 with 20 claims, was granted nearly two years after its March 2024 filing date.
What changed
The USPTO issued Patent US12597026B2 to PayPal, Inc. for a blockchain-based transaction validation and storage system. The patent describes operations including receiving transaction data, incorporating transaction data into a challenge-response authentication process for data block verification, using cryptographic hash data from prior blockchain blocks, and validating data blocks based on the security process. The 20 granted claims cover the system architecture, cryptographic verification methods, and blockchain integration mechanisms.
For PayPal, this grant reinforces intellectual property protection for blockchain transaction validation technology in financial services. For competitors in fintech, digital payments, and cryptocurrency services, the patent defines a protected method for blockchain-integrated transaction authentication that may require design-around analysis if developing similar systems. The CPC classifications (G06Q 20/ series for financial transaction systems and H04L 9/ series for cryptographic mechanisms) indicate the scope of protected subject matter.

Abstract
A system includes a memory and a processor configured to execute computer instructions stored in the memory that when executed cause the system to perform operations. The operations include receiving transaction data associated with a transaction via a transaction component. The operations include incorporating at least a portion of the transaction data into a security process associated with challenge-response authentication of a data block for the transaction data. The data block includes cryptographic hash data for another data block in a blockchain associated with the data block. The operations include validating the data block associated with the blockchain based on the security process.
