A diamond is a single address with the functionality of multiple contracts that are independent from each other but can share internal functions, libraries and state variables

I tried to make it very clear what an Ethereum diamond is and how it works in the latest revision of the Diamond Standard. Did I succeed?

## Simple Summary

A new smart contract paradigm that works today.

A diamond is a contract that implements the Specification in this standard.

Diamonds are powerful, organized, modular, optionally upgradeable, flexible, unlimited in size, and transparent.

I’m very much a beginner, but I was able to follow what you wrote for the most part. I get what the diamond pattern is and, had I the Solidity knowledge, I could start writing one.

Personally, I’d like to see more examples of facets and how they’re written. The code examples really helped solidify the concepts.

That’s great. Have you seen the Diamond reference implementation? It is good to look at how its contracts are written: https://github.com/mudgen/Diamond And the reference implementation is useful to get started writing a diamond.

More examples are coming. Also, I hope bloggers/writers will write some diamond tutorials.
