PART 1Executive Overview
1Definition

Blockchain for decentralized identity management is a technology that leverages blockchain's immutable ledger to create secure, self-sovereign digital identities. These identities are stored on a distributed network without relying on central authorities.

2Problem It Solves

Addressing issues such as identity theft, fraud, and privacy breaches by providing a tamper-proof and decentralized solution for managing digital identities.

PART 2Technical & Manufacturing
4How It Works

Each identity transaction or update is recorded as a block in the blockchain, creating an unalterable and transparent history of the identity’s lifecycle. Users control their own keys to authenticate transactions, ensuring that only they can manage their data.

5Materials Used
6Manufacturing / Creation Process

The manufacturing process involves developing smart contracts and cryptographic protocols to ensure the security and integrity of the blockchain network. No physical goods are manufactured; rather, it is software development focused.

7Build Process

Developers create and test smart contracts that define the rules for identity verification and data access. These contracts are then deployed on a blockchain platform such as Ethereum or Hyperledger Fabric.
