Thanks to the widespread deployment of TLS, users can access private data over channels with end-to-end confidentiality and integrity. What they cannot do, however, is prove to third parties the provenance of such data, i.e., that it genuinely came from a particular website. Existing approaches either introduce undesirable trust assumptions or require server-side modifications. Users' private data is thus locked up at its point of origin. Users cannot export data in an integrity-protected way… Expand
N-for-1 Auth: N-wise Decentralized Authentication via One Authentication
TLDR
N-for-1-Auth is presented, a system that preserves distributed trust by enabling a user to authenticate to servers independently, with the work of only one authentication, thereby offering the same user experience as in a typical centralized system. Expand
ROSEN: RObust and SElective Non-repudiation (for TLS)
A versatile non-repudiation service that can be used directly and without application-specific modifications is desirable in many realistic use-cases. Since TLS is one of the most popular currentExpand
Wolverine: Fast, Scalable, and Communication-Efficient Zero-Knowledge Proofs for Boolean and Arithmetic Circuits
TLDR
A new protocol for constant-round interactive ZK proofs that simultaneously allows for a highly efficient prover and low communication and an improved subfield Vector Oblivious Linear Evaluation (sVOLE) protocol with malicious security that is of independent interest is presented. Expand
Decentralized Reputation
TLDR
This work develops a privacy-preserving reputation scheme for collaborative systems such as P2P networks in which peers can represent themselves with different pseudonyms when interacting with others, allowing honest peers to maintain their good record even when switching to a new pseudonym while preventing malicious ones from making a fresh start. Expand
An event driven framework for smart contract execution
TLDR
The platform design of EDSC is presented, which shows a 2.2 to 4.6 times reduced total latency of event-triggered smart contracts, demonstrating the effectiveness of the design in supporting time-sensitive applications. Expand
Blockchain Oracle Design Patterns
TLDR
This paper will study and analyze blockchain oracles with regard to how they provide feedback to the blockchain and smart contracts, and classify the blockchain oracle techniques into two major groups such as voting-based strategies and reputationbased ones. Expand
CanDID: Can-Do Decentralized Identity with Legacy Compatibility, Sybil-Resistance, and Accountability
TLDR
CanDID provides strong confidentiality for user’s keys, real-world identities, and data, yet prevents users from spawning multiple identities and allows identification (and blacklisting) of sanctioned users. Expand
CeFi vs. DeFi - Comparing Centralized to Decentralized Finance
TLDR
In this work, a structured methodology is provided to differentiate between a CeFi and a DeFi service, and it is shown that certain DeFi assets do not necessarily classify as CeFi assets, and may endanger the economic security of intertwined DeFi protocols. Expand
Diving Into Blockchain's Weaknesses: An Empirical Study of Blockchain System Vulnerabilities

TLDR
This research presents a novel and scalable approach to solve the challenge of integrating nanofiltration and X-ray diffraction analysis into the design of smart grids. Expand
EDSC: An Event-Driven Smart Contract Platform
TLDR
This paper presents EDSC, a novel smart contract platform design based on the event-driven execution model as opposed to the traditionally employed transaction- driven execution model, and proposes its design under the Ethereum framework, and the design can be easily adapted for other existing smart contract platforms.

Town Crier: An Authenticated Data Feed for Smart Contracts
TLDR
An authenticated data feed system called Town Crier is presented, which acts as a bridge between smart contracts and existing web sites, which are already commonly trusted for non-blockchain applications and defines and proves its basic security properties in the Universal Composibility (UC) framework.
