📌 Blockchain-Based Identity Systems Summary
Blockchain-based identity systems use blockchain technology to create and manage digital identities in a secure and decentralised way. Instead of storing personal data on a single server, information is recorded across a distributed network, making it harder for hackers to tamper with or steal sensitive data. These systems often give users more control over their own information, allowing them to decide who can access specific details about their identity.
🙋🏻♂️ Explain Blockchain-Based Identity Systems Simply
Imagine a digital ID card that only you can control, and instead of being kept in one office, copies of the information are securely stored across many places at once. This means you can prove who you are without worrying that someone can easily steal or change your details, and you decide who gets to see what.
📅 How Can it be used?
A project could use blockchain-based identity systems to let users log in securely without needing a central username and password database.
🗺️ Real World Examples
The city of Zug in Switzerland introduced a blockchain-based digital ID for residents. With this system, citizens can prove their identity for local government services, sign documents electronically, and access e-voting, all while maintaining control over their personal data.
Some universities use blockchain-based identity systems to issue digital diplomas. Graduates receive a secure digital certificate they can share with employers, who can then verify its authenticity instantly without needing to contact the university.
✅ FAQ
How does a blockchain-based identity system keep my personal information safer?
A blockchain-based identity system spreads your information across many computers instead of keeping it all in one place. This makes it much harder for hackers to break in and steal or change your details. You also get more control over who can see your information, so you can share only what is needed.
Can I choose what information to share with others using a blockchain identity?
Yes, these systems are designed to give you more say over your own data. For example, you might only need to prove you are over 18 without revealing your exact date of birth. You decide what to share and with whom, helping to keep your private details safe.
What are some benefits of using blockchain for digital identity compared to traditional methods?
Blockchain systems reduce the risk of large data leaks because there is no single database for people to target. They also let you manage your own identity, which can make signing up for services faster and easier. Plus, you can use one digital identity in many places, which helps cut down on paperwork and forgotten passwords.

💡Other Useful Knowledge Cards
Knowledge Base System
A knowledge base system is a digital tool that stores, organises, and retrieves information to help users find answers to their questions. It can contain articles, guides, FAQs, and other resources, making information easy to access and manage. These systems are often used by businesses and organisations to support staff and customers, helping them solve problems efficiently.
Cloud Infrastructure Security
Cloud infrastructure security refers to the set of policies, controls, technologies, and processes designed to protect the systems and data within cloud computing environments. It aims to safeguard cloud resources such as servers, storage, networks, and applications from threats like unauthorised access, data breaches, and cyber-attacks. Effective cloud infrastructure security ensures that only authorised users and devices can access sensitive information and that data remains confidential and intact.
Distributed Hash Tables
A Distributed Hash Table, or DHT, is a system used to store and find data across many computers connected in a network. Each piece of data is assigned a unique key, and the DHT determines which computer is responsible for storing that key. This approach allows information to be spread out efficiently, so no single computer holds all the data. DHTs are designed to be scalable and fault-tolerant, meaning they can keep working even if some computers fail or leave the network.
Voice Broadcasting
Voice broadcasting is a technology that allows pre-recorded voice messages to be sent automatically to many phone numbers at once. It is often used by businesses, organisations, and government agencies to communicate quickly with a large group of people. This method saves time compared to making individual calls and ensures that the message is delivered consistently to everyone.
Data Virtualization
Data virtualisation is a technology that allows users to access and interact with data from multiple sources without needing to know where that data is stored or how it is formatted. Instead of physically moving or copying the data, it creates a single, unified view of information, making it easier to analyse and use. This approach helps organisations work with data spread across different databases, cloud services and storage systems, saving time and reducing complexity.
