Design and develop a software technique based on differential privacy and its extensions to ensure an optimal trade-off between utility and the privacy of personal data in graphs and crowdsourcing systems for centralized and decentralized models. The goal is to implement a privacy protection solution for users while maintaining system efficiency.

Propose solutions for the challenges of current blockchain networks, such as scalability, latency, and privacy. The solutions are based on Layer 2 blockchain technology, such as the Lightning Network.
Design and develop a blockchain platform containing profiles that can be used to exchange expertise, services, or products. This platform can generate cryptocurrencies and may be used as a management system to track services and products. Numerous privacy-preserving solutions must be proposed to protect user data.
