Introduction to Decentralized Identity Management

Last quarter, our team discovered the importance of decentralized identity management when we were building a blockchain-based application. We tried to use traditional identity management systems, but they were not scalable or secure. Here's what we learned when we started exploring Polkadot, Substrate, and Verifiable Credentials.

The Problem with Traditional Identity Management

Traditional identity management systems are centralized, which makes them vulnerable to single-point failures and data breaches. They are also not scalable, which makes them unsuitable for large-scale applications. When we tried to use traditional identity management systems for our application, we encountered several issues, including poor performance and high latency.

How Polkadot, Substrate, and Verifiable Credentials Work

Polkadot is a decentralized platform that enables interoperability between different blockchain networks.
