## Paradox's Perspective

### Project Overview
During the residency, the main objective was to achieve multisig confirmation for Safe Global using zkEmail. This feature has multiple use cases, such as providing two-factor authentication for your safe account or enabling DAOs to approve transactions by simply replying to an email, which can be challenging when coordinating with safe signers. We were excited to find partners who were interested in integrating email wallet signers into their DAOs during the residency. Another target was to complete the audit fixes for zk-regex, which was conducted by zkSecurity and successfully achieved.

### Projects that were a part of this residency:
- zkEmail
- Cursive
- ZK-P2P
- Proof of Passport
- MynaWallet
- AnonAadhar
- MoPro
- App Attest
- and more

You can watch all the project demos [here](https://www.youtube.com/live/rT7zLiOYX8s?si=BcqlRg03BeTr9AuV).

### Learnings
Throughout the month, we encountered numerous theoretical and practical learnings. Several workshops and lectures covered topics such as **Binius**, **Fully Homomorphic Encryption (FHE)**, and a new proving scheme called **zkBoogi**. Some of these videos and lectures are available on our [YouTube channel](https://www.youtube.com/@sigsing/videos). Building scalable projects presented a rewarding challenge. We discovered that working together in person accelerates development significantly compared to remote coordination. Additionally, it was fascinating to gain an in-depth understanding of other residents' projects.

### Project Synergies
The difference between working in person and remotely was like night and day. Discussing the architecture of the multisig confirmation in person was incredibly efficient and fast.

Preparing our demos was greatly aided by having people test them end-to-end, ensuring everything worked smoothly. This helped us identify critical bugs and scalability issues that might have otherwise been missed.

### Personal Reflections
Overall, I feel the residency was a great success and a testament to the benefits of in-person collaboration for fast development and growth of projects with Privacy Scaling & Explorations (PSE). The most fun memories were from the field trip to Kyoto.
