General Grant Proposal - eSim Wallet

• Project: Blockchain powered eSIM

Project Overview

Overview

This proposal is for a renewal grant for a mobile-based hardware crypto wallet using eSIMs with remote provisioning of accessibility. The initial grant details can be found https://hackmd.io/swQfOzVmR4OuwqER7EeOfQ

Project Details

In the first grant, the team successfully completed a proof of concept demonstrating that remote provisioning and issuing of private keys over eSIM is feasible. They also explored and refined the process for launching this technology in a production environment, with the goal of onboarding many non-Web3 users to a cryptographically secure environment.

This renewal grant will support major activities such as production release, Devcon engagement, and research and development on Zero-Knowledge (ZK) technology, among others. More details are provided in the roadmap section.

The nature of this proposal involves using flexible deliverables while adhering to the projected roadmap which can be found below. During the grant period, team will be non-profit and not take any commision from the data plan sale in order to accerlate the adoption of this technology. The team is non-profit and anything earned from the sale of eSIMs and data bundles will be directly used to maintaining servers, sponsoring gas fees using paymasters and remaining goes to incentivising users.

Development Roadmap

The roadmap for the next six months will focus on production release, incorporating feedback, and R&D on OpenRSP. The modern cryptography aspect of this project is in this grant proposal, calling it OpenRSP(an advance Remote SIM Provisioning), utlising the concept Zero Knowledge Proof , MPC and more for data integrity and removal of trusted third party for open source eSIM stack benefitting different stakeholders and users.

July - September (3 months)

1. Implement account abstraction and enable passkey authentication, replacing device wallet smart contracts.
2. Submit the final smart contract for security audit (PSE audit team support requested).
3. Prepare for entity registration, necessary for production release from Airalo and eSIM (advised by EF’s lawyer; it will be an LLC with no profit generation).
4. Design and develop Android and iOS apps for users to purchase data plans (with support from Pollen Labs).
5. Conduct closed beta testing for 100-300 users.
6. Submit a Devcon proposal to offer the wallet as an official perk for all attendees.
7. Draft and review OpenRSP*.

October - December (3 months)

1. Iterate based on closed beta results.
2. Polish and prepare for Devcon release.
3. Review and design OpenRSP engineering, followed by implementation.
4. Release the app in multiple countries via iOS App Store and Google Play Store.
5. Identify use cases and collaborate with other protocols to enhance the experience.

Addtional info

Arpit and Mitsu agreed that the team will only use the fund for open-source development and not for others e.g., the fee to set up an entity.

What's OpenRSP?

Open Source Remote SIM Provisioning (OpenRSP) systems should inherit the secure and efficient activation of embedded SIMs (eSIMs) in a variety of devices from traditional RSP and utilise modern cryptography for data integrity resulting in trustworthy systems by removing trusted parties involved in the system.

Recent advancements in cryptographic techniques have significantly enhanced both the security and efficiency of these systems.

Exploring the application of state-of-the-art cryptography, including Zero-Knowledge Proofs (ZKP) and garbled circuits, to develop a highly secure, privacy focused and trustworthy RSP framework.

Designing this with the motivation of incorporating ZKP for device and user authentication, ensuring that authentication can be performed without revealing sensitive information to establish a secure handshake for network access. This method leverages the properties of ZKP to maintain privacy while proving possession of valid credentials. Additionally, garbled circuits are employed to secure profile management operations, allowing encrypted data to be processed without exposing it, thus ensuring end-to-end confidentiality.

We address the key management challenge through Identity-Based Cryptography (IBC). By using identities as public keys, IBC simplifies the key distribution process and enhances security. This framework is designed to be open-source, promoting collaboration among various stakeholders in the ecosystem and fostering innovation and interoperability.

We will be providing a detailed analysis of the theory, implementation, challenges and potential benefits of incorporating these advanced cryptographic techniques into eSIM technology.

Our result will demonstrate that the proposed framework not only significantly improves the security and privacy of the RSP process but also lays the foundation for a more trustworthy and collaborative environment in the digital communication domain.
