Deep Motion Masking for Secure, Usable, and Scalable Real-Time Anonymization of Virtual Reality Motion Data (read more here)
Interest and investment in Virtual Reality (VR) and the metaverse have surged with major tech companies entering the space. However, concerns arise as studies show that motion tracking telemetry in VR is as identifiable as fingerprint scans, posing privacy risks. Despite previous attempts to anonymize VR data, a state-of-the-art identification model is presented, bypassing known defenses. A new "deep motion masking" approach is proposed for real-time anonymization, demonstrating increased usability and privacy in a large-scale user study (N = 182).

Landscape for hashing-based SNARKs (read more here)
In my latest blog posts, I delve into work just unveiled by Ben Diamond and Jim Posen (D&P) that, in my view, reshapes the landscape for hashing-based SNARKs. D&P have fine-tuned the Ligero/Brakedown polynomial commitment scheme particularly when it's used to commit to small values. When combined with sum-check-based SNARKs like Lasso and Jolt, this paves the way for much faster SNARKs for standard hash functions like Keccak.

Trac, Tap, and Pipe: Pioneering Protocols in the Bitcoin Ecosystem (read more here)
TTP — Trac, Tap, and Pipe — marks a significant evolution in the Bitcoin ecosystem. Trac core serves as a decentralized indexer and oracle, enhancing data management and security. Tap extends the ordinals protocol, boosting liquidity and introducing DeFi features. Pipe, a fork of ordinals, integrates advanced functionalities into Bitcoin. Together, these protocols signify a shift from a meme-centric approach to a focus on utility and infrastructure, paving the way for future innovations in cryptocurrency.
Blockchain-Based Distributed Network Architecture for Internet of Things (read more here)
IoT networks, widely deployed for convenience and cost-efficiency, face vulnerability issues due to inadequate self-protection and imperfect architectures. This exposes IoT devices to cyber threats, jeopardizing information security and availability. Thus, safeguarding network infrastructure and ensuring data protection from malicious entities are crucial in communication network design. The thesis primarily explores two IoT scenarios: routing protection and authentication for smart community devices.

Curve was exposed for having an oracle manipulation vulnerability (read more here)
An attacker only needs a single extra block in most pools to manipulate the Curve price_oracle 10x-500x higher. This manipulation can be hidden such that there is no possible way to look at the pool and know that it is being manipulated.
The intents bridge: Cross-chain value transfer and the future of interoperability (read more here)
In the cross-chain ecosystem, users rely on bridges to transfer value. Value transfer bridges use onchain liquidity or offchain liquidity to fill orders. Intents designs are likely to dominate in the future as using offchain liquidity offers users meaningful savings and a better user experience.

A comprehensive analysis of Hong Kong's Virtual Asset Service Provider (read more here)
To align with the October 2022 Policy Statement on Hong Kong's virtual asset development, the Legislative Council passed amendments to the Anti-Money Laundering Ordinance on December 7, 2022. This marks the official commencement of the new Virtual Asset Service Provider (VASP) licensing system on June 1, 2023. The article provides insights into the VASP system's background, virtual asset definitions, license application requirements, exchange compliance, dual licensing, and transitional arrangements, offering clarity on the impending regulatory framework.
