# Solving Real-World Failures
Current identity systems have well-documented failures:
**Problem: Disconnected Databases**\
Your driver's license database doesn't talk to your tax records, which don't connect to your health records. Result? **Endless repetition and inconsistency**.
**Solution:**\
Blockchain creates a **single source of truth** that all authorized parties can verify without storing duplicate copies.
***
**Problem: Outdated Records**\
Change your address, but **some database doesn't update?** You might get denied services or receive critical documents at the wrong location.
**Solution:**\
Every update to your blockchain identity is **permanently recorded with a timestamp**. All authorized parties see the most current, verified information instantly.
***
**Problem: Identity Fraud**\
Criminals **create fake identities or steal real ones** to access benefits, commit crimes, or open fraudulent accounts.
**Solution:**\
Blockchain makes every identity immutable and traceable. Any attempt to tamper with data becomes **immediately evident** to all participants in the network.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/introduction-to-blockchain-technology/the-future-of-technology/solving-real-world-failures.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
