The following discussion highlights the prototype's ability to enable uniform data access across multiple blockchains, facilitating cross-chain query processing. It notes limitations, including the current focus on equality-based filters and the lack of advanced blockchain-specific features. The section concludes with an outlook on future research opportunities, such as improving blockchain data storage and enhancing decentralized application platforms.

Desk crits, adapted for CS1, provide informal, personalized feedback to students as they solve problems, helping instructors track progress, adjust difficulty, and offer support.

Discover groundbreaking insights from blockchain innovator Douwe Faasen in this exclusive interview. Learn how his journey—from early Bitcoin faucets to launching HyveDA—is reshaping data availability, scalability, and decentralization on Ethereum and beyond. Explore the future of rollups, ZK technology, and decentralized infrastructure in this must-read conversation.

This section demonstrates how the prototype application processes typical blockchain queries, with examples showing the identification of transactions within blocks, timestamp-based filtering, and cross-chain data retrieval. It highlights the ability to query across multiple blockchains (e.g., Ethereum and Avalanche), locate transactions with matching timestamps, and track asset transfers, making it suitable for scenarios like cross-chain swaps.

The study adapts Problem-Solving Studio (PSS) with pair programming, using dynamic scaffolding and a "problem ladder" to keep students engaged, challenged, and motivated while learning programming.

Mobile pentesting is about finding creative ways to break into an app. It’s different from standard web pentesting because mobile apps: Android and iOS each have their own rules, security models, and quirks. Common challenges include dealing with root/jailbreak detection, bypassing SSL pinning, and analyzing both client-side and server-side logic.

This literature review highlights the benefits and challenges of pair programming in education, emphasizing its positive impact on software quality and student learning, while noting the need for better instructional design and pairing strategies.

This section demonstrates the feasibility of implementing the proposed cross-chain query language through a prototype application. The application, built using Python 3.9 and web3.py, interacts with local blockchain nodes (Bitcoin, Ethereum, Cardano, and Avalanche) to execute queries. The implementation was tested on a consumer-grade laptop with fully validating nodes, showing that query performance is dependent on local hardware and not affected by network latency....

Object-oriented programming, inheritance, and subtyping may have specific meanings that don't translate into other languages, depending on the first language you learn.

The appendix illustrates a real Bitcoin testnet multisig transaction, showing how the protocol ensures trustless transactions with the use of private keys, digital signatures, and publicly available blockchain data.

Multisig technology offers a promising, trustless solution for cross-border disputes, but it faces challenges in gaining widespread use in international arbitration due to its complexity and the slow adoption by arbitration institutions. Despite its potential, multisig must align with existing legal frameworks to become a standard method for resolving disputes.

Bitcoin’s multisig arbitration process, despite its technological self-enforcement, cannot be viewed as an autonomous legal order due to its recent adoption, privacy concerns, and lack of widespread commercial usage. It is better suited for integration into international arbitration law.

Multisig e-awards, though self-enforcing, require authentication for legal recognition. The process varies by jurisdiction, but under flexible common law approaches, electronic signatures and transaction data can authenticate them.

Blockchain multisig transaction data could fulfill the "in writing" requirement for arbitration awards, providing verifiable, unaltered proof stored in a permanent distributed ledger.

Blockchain-based electronic signatures could be legally valid for arbitration awards. This paper examines the role of digital signatures under the eIDAS Regulation and arbitration law.
