Privacy-focused dApps

This track would challenge participants to develop decentralized applications that prioritize privacy. Examples of dApps could include private messaging platforms, anonymous social networks, or privacy-focused file-sharing tools.

Privacy-enhancing smart contracts

In this track, participants would be tasked with creating smart contracts that incorporate privacy features. This could include protocols that use zero-knowledge proofs, ring signatures, or other privacy-preserving techniques to keep user data confidential.

Privacy in DeFi

With decentralized finance becoming increasingly popular, it's more important than ever to prioritize privacy in these transactions. This track would ask participants to develop tools, platforms, or protocols that enhance privacy in the DeFi space. For example, this could include anonymous lending platforms, privacy-focused stablecoins, or tools for protecting transactional data.

Privacy and security for blockchains

Finally, this track would challenge participants to develop new approaches to securing and protecting blockchain networks. This could include new consensus mechanisms that prioritize privacy, techniques for enhancing network privacy and confidentiality, or tools for safeguarding against malicious actors.

Privacy-focused data analytics

In this track, participants would be challenged to develop tools, platforms or protocols that enable secure, private, and anonymous data analytics. The goal is to explore how to make data analytics more accessible while still maintaining user privacy.

Privacy-enhancing hardware

With the rise of the Internet of Things (IoT), there is a growing need for hardware that prioritizes user privacy. In this track, participants would be asked to develop hardware devices that incorporate privacy features such as encryption, decentralized identity, or secure communication protocols.

Privacy and AI

As artificial intelligence (AI) becomes more prevalent, it is essential to consider how to protect user privacy in these applications. This track would challenge participants to develop privacy-preserving AI tools or platforms that enable secure and confidential data analysis and decision-making.

Privacy and digital identity

Digital identity is becoming increasingly important as we shift to a more digital world. In this track, participants would be asked to explore innovative ways to safeguard user identity and personal information while still enabling seamless access to digital services and applications.


Week 1

Submission Deadline and Initial Judging

Participants will submit their project proposals by the deadline, outlining their ideas and describing how their projects incorporate privacy features. The judges will review the proposals and select the most promising projects to move on to the next round.

Week 2-3

Project Development

The selected participants will have two weeks to develop their projects. During this time, participants will have access to mentors and resources to help them develop their ideas and implement their privacy features. There will be regular check-ins with mentors to ensure that participants are making progress and to provide additional support as needed.

Week 4

Final Judging and Presentations

The finalists will be invited to present their projects to a panel of judges and a live audience.
Each participant will have a fixed amount of time to demonstrate their work and answer questions from the judges.

The judges will evaluate the projects based on features defined below.

The winners will be announced at the end of the week, and prizes will be awarded to the top performers.

Throughout the month, there will be networking opportunities for participants, mentors, and judges to connect and share ideas. There may also be opportunities for participants to showcase their projects to potential investors or partners in the privacy and decentralized finance space.

In addition, there may be educational sessions, workshops, and panel discussions on topics related to privacy, decentralized finance, and blockchain technology. These sessions would provide participants with additional insights and knowledge to inform their projects.

Overall, the goal of the program is to provide participants with a supportive and collaborative environment in which to develop their ideas and to highlight the importance of privacy in the decentralized finance ecosystem.
