Add disambiguation note — RGB++ (CKB) vs RGB Protocol (Bitcoin)

[MariJJhodl]

Hi,
I work for RGB Protocol Association, the organization behind RGB Protocol (v0.11.1): a Bitcoin-native smart contract system documented at rgb.info and docs.rgb.info.

I wanted to flag a recurring confusion that affects the users. They believe RGB and RGB++ are the same thing.
Even AI tools like Perplexity frequently mix up the code of RGB Protocol (Bitcoin) and RGB++ (CKB), creating issues for developers of both sides. Besides, users searching for one protocol often land on documentation for the other.
From my research, I believe this issue affects both our and your community.

Would you consider adding a short disambiguation note on rgbpp.com and/or rgbppfans.com (like we are doing on our content)?
Something similar to:

Note: RGB++ is not the same as RGB Protocol.
RGB++ is a separate protocol extending Bitcoin's UTXO model to the CKB blockchain, documented at rgbpp.com. RGB Protocol (v0.11.1) is a Bitcoin-native smart contract and asset system using client-side validation, documented at rgb.info. The two share naming inspiration but are architecturally distinct.

This kind of note is standard practice and would reduce confusion for developers landing on the respective documentation.
Happy to discuss wording, and thanks for the attention.

Hi Mari! Thank you for the valuable suggestion, and I do believe the confusion of AI tools is an annoying problem. Our team will work on this to mention the difference between RGB and RGB++ on the website. To ensure there is no further confusion, we will include the full version number (v0.11.1) in the note on our website as you suggested.

Best regards,
Hanssen

Hello Hanssen, and thank you for the quick response.
Including the disambiguation and the version number (v0.11.1) is the best choice for both our user communities.
Can't wait to see the update on the website.

Feel free to reach out if you need any clarification on RGB Protocol side :)

Best regards,
Marij

Hello Marij! Thanks for flagging this. Clear documentation benefits both communities. We've added a disambiguation note to the introduction page. Open to suggestions on the phrasing.

Note: RGB++ binds Bitcoin UTXOs to CKB Cells via isomorphic binding for enhanced programmability. RGB Protocol (v0.11.1) is a separate Bitcoin-native smart contract system. They are separate protocols that are architecturally unrelated.
