Abstract
With the emergence of blockchain and smart contracts, traditional digital applications 1
such as identity management, supply chain management, banking and finance etc. are expected 2
to be transformed into Decentralized Applications (DApps). Blockchain interoperability is a new 3
and exciting aspect of blockchain technology that is quickly gaining popularity in many industries. 4
However, the widespread use of blockchains has not yet been achieved because DApps running on the 5
blockchain using smart contracts require access to authentic off-chain data. Users are more conscious 6
of their personal data privacy and consequently are more reluctant to share their data, posing a 7
challenge in the adoption of DApps. To solve this challenge, we present a novel quantum-resistant, 8
data authentication and zero-knowledge proof scheme named zk-DASTARK. Based on our proposed 9
scheme, we present a novel framework which can be used to feed authenticated off-chain data to 10
DApps without compromising user data privacy. Our proposed framework is quite efficient against 11
well-known off-chain data authentication frameworks. The proposed framework is implemented on 12
state-of-the-art quantum-resistant IOTA Blockchain and is highly efficient as it takes approximately 13
60 ms to generate a proof and approximately 10 ms to verify a proof.
