“…Moreover, TEE is known to be prone to attacks like meltdown [15] and spectre [16]. In late 2021, Zhipeng et al [26], proposed a solution named select-storage to feed external data to smart contracts. The proposed solution offers an efficient storage of data being fed into the smart contract but, no mechanism for data authentication and privacy has been offered.…”

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.

“…of deterministic routines (which cannot be changed after being published on the network) to facilitate the registration and consultation of data. Among the most diverse applications, SCs have been used to mediate communication between IoT solutions and DLTs [6]. In addition, Distributed Applications (DApps) are based on SCs to deliver a user-friendly solution for monitoring chain actors to interact with data in the DLT [7].…”

The complementarity of distributed ledger technologies such as Blockchain and the Internet of Things has gained increasing attention in the literature. In order to facilitate the immutable validation and registration of the data collected by the devices, the so-called smart contracts have been used and distributed applications have been developed to increase the adhesion of the actors. Thus, this work presents a tool for experimentation to evaluate the performance and scalability of distributed applications in the context of the Internet of Things. The proposed tool is flexible and allows experimentation with different technologies and configurations. This work contributes to the convergence among immutable information recording, deterministic computation, and sensing of physical world quantities.
