Blockchain Read Receipt System Using Cryptographic Verification
Summary
USPTO published patent application US20260100844A1 for a blockchain-based read receipt system. The invention by Liuxuan Pan and Adina Wineman describes a computer-implemented method for requesting cryptographic read receipts for messages using blockchain transactions locked by cryptographic puzzles. The application was filed on September 4, 2023 under Application No. 19115136 and assigned CPC classifications in H04L cryptography categories.
What changed
USPTO published patent application US20260100844A1 for a blockchain-based read receipt verification system. The application discloses a method where a sender generates a cryptographic puzzle tied to a message, locks a blockchain output with a locking script requiring the puzzle solution, and determines message receipt by detecting output unlock. The system uses H04L cryptographic classifications for blockchain verification.
For technology companies developing messaging or blockchain systems, this application indicates potential patent activity in cryptographic verification methods. Parties should monitor the prosecution of this application for claim scope and consider whether their systems may implicate similar cryptographic verification approaches if the patent issues.
What to do next
- Monitor for patent grant or examiner actions
- Review claims for potential licensing implications

Abstract
A computer-implemented method of requesting a read receipt for a message using a blockchain, the read receipt evidencing that the message has been opened, the method being performed by a first party and comprising: sending the message, and/or an encrypted version thereof, to a second party; generating a cryptographic puzzle based on the message; generating a request blockchain transaction, wherein the request blockchain transaction comprises a first output locked by a first locking script, wherein the first locking script is configured to, when executed together with a first unlocking script of a response blockchain transaction, require the first unlocking script to comprise a solution to the cryptographic puzzle; and determining that the message has been opened in response to determining that the first output has been unlocked.
