$\pi$QLB: A Privacy-preserving with Integrity-assuring Query Language for Blockchain. (arXiv:2212.14141v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The increase in the adoption of blockchain technology in different
application domains e.g., healthcare systems, supplychain management, has
raised the demand for a data query mechanism on blockchain. Since current
blockchain systems lack the support for querying data with embedded security
and privacy guarantees, there exists inherent security and privacy concerns on
those systems. In particular, existing systems require users to submit queries
to blockchain operators (e.g., a node validator) in plaintext. This directly
jeopardizes users' privacy as the submitted …
