A secure communication is established between the lightweight blockchain client and the TEE. The TEE receives a request from the lightweight blockchain client for at least one transaction or address of the lightweight blockchain client. The TEE obtains unspent transaction output (UTXO) information with respect to the request from the lightweight blockchain client from a UTXO database by oblivious database access using an oblivious RAM (ORAM) protocol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system of preserving privacy for usage of lightweight blockchain clients","description":"A method of preserving privacy for usage of a lightweight blockchain client in a blockchain network includes using, in a full blockchain node of the blockchain network, a trusted execution environment","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11303445","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
