METHOD, APPARATUS, AND NON-TRANSITORY MACHINE-READABLE STORAGE MEDIUM FOR BLOCKCHAIN TRANSACTIONS

Resumen de: WO2026167065A1

The present disclosure relates to a method for secure blockchain transactions using a decentralized multi-hop proxy network (DMHPN). The method comprises obtaining an encrypted message containing original transaction information, which is routed through a plurality of proxy nodes. Each proxy node decrypts its respective segment using a unique Elliptic Curve Diffie-Hellman (ECDH) shared encryption key to determine the next hop. The final proxy node decrypts the complete transaction data and submits it to the blockchain. The encrypted message excludes identifiers of the transaction initiator and destination blockchain node, enhancing privacy. This method improves security and decentralization by making only the intended proxy node access its segment of the data, maintaining anonymity throughout the transaction while preventing unauthorized access and ensuring privacy in blockchain interactions.

Desimone Jason

Resumen de: US20260236855A1

The present disclosure describes a system and method for a cryptographic and digital ticketing platform that extends the interconnectivity between artist, event and attendees. Digital articles are secured by way of blockchain technology, as well as cryptographic keys that document these interactions within a network and on a digital wallet. Tickets and articles are escrowed, locked, or staked for the purpose of generating a yield or return on the investment for authenticated and verified event attendee. The ecosystem for event and fan interactions is thereby elevated by offering incentives for attendance, allowing artists, attendees, and venues to share and deposit digital media into encrypted wallets, and offering rare digital assets in addition to a monetary return on the investment of their ticket or as a reward for their fan loyalty. Post-event, artists and events distribute digital rewards, collectibles, NFTs and exclusive interactions to event attendees and loyal fans, through one central application. Biometrics and geolocation tagging may also assist with attendance and monitorization of attendees for potential rewards and interactions.
