Blockchain and eSIM are disruptive technologies in the mobile industry facing resistance from established players. Despite this, they are slowly being adopted due to innovation and companies that see the value in change. Both technologies have a secure future and it's only a matter of time before eSIMs become the norm, with blockchain helping to drive their adoption.

How i started,

In the summer of 21, I began studying blockchain development. Combining it with my electronics and communication engineering background, I created a project titled "Blockchain-based Dynamic Spectrum Sharing" in my 7th semester (July22 - Nov22). This platform enabled more efficient spectrum auctions and later i found out there’s a whole new space combining these two stacks and an entirely new field of study.
Here’s the repo of that project.

EthIndia Fellowship 3.0

In this fellowship i’m aiming to build a working prototype, if not

At least i’ll end this fellowship with a feasible sustainable design of an eSIM which is backed by blockchain and cryptography resulting in multiple solution such as:

• Fraud Management

• Identity as a Service

• 5G enablement

• IOT connectivity

• Security

Introduction

The development of a blockchain-powered eSIM (embedded SIM) on the Ethereum network is a critical step towards the creation of a decentralized phone system that provides users with greater security, privacy, and efficiency in their communication options. The use of smart contracts on the Ethereum network will ensure that the eSIM is decentralized and not controlled by a single entity, providing users with greater control over their communication options.

NOTICE: Building a blockchain powered eSIM will require discussions followed by adjustments with carrier providers and device companies.

eSIM

An eSIM(embedded-SIM) is a form of programmable SIM card that is embedded directly into a device.

Instead of an integrated circuit located on a removable universal integrated circuit card (UICC), typically made of PVC, an eSIM consists of software installed onto an eUICC chip permanently attached to a device.

Once an eSIM carrier profile has been installed on an eUICC, it operates the same as a physical SIM, complete with a unique ICCID and network authentication key generated by the carrier.

The eSIM standard was first released in 2016; since that point, eSIM has begun to replace physical SIM in domains including cellular telephony.

Since 2010, the GSMA had been discussing the possibility of a software-based SIM.

To avoid any confusion, suggesting the following way of looking at the definition:

"eSIM is the whole service - SIM + eUICC + platform
eUICC is the software that allows provisioning."

Abstract

This project aims to build a blockchain-powered eSIM solution that integrates with the user's crypto wallets. The unique ID of the eSIM will be mapped with the user's crypto wallets, allowing them to access applications, make transactions, and more, with just a single step process using their fingerprint. The eSIM will provide cryptographic identity services and will be backed by zero-knowledge proofs to ensure the privacy and security of the user's data.

Overview

The goal of this project is to create a seamless and secure eSIM solution that integrates with the user's crypto wallets. The unique ID of the eSIM will be linked to the user's crypto wallets, enabling them to access applications and services using their fingerprints. The eSIM will provide cryptographic identity services and will be backed by zero-knowledge proofs to ensure the privacy and security of the user's data. The blockchain technology will be used to store and manage the eSIM data, providing a secure and decentralized solution that is resistant to data breaches and other security threats.

Metrics

The success of this project will be measured by a number of key metrics, including:

• User adoption: the number of users who have adopted the blockchain-powered eSIM solution

• User satisfaction: the level of satisfaction reported by users of the eSIM solution

• Security: the number of successful and attempted security breaches, and the success rate of security measures in preventing these breaches

• Interoperability: the number of different applications and services that the eSIM solution is compatible with

Acceptance Criteria

The following are the acceptance criteria for this project:
