Frequently asked

Does The Quantum Protocol work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version The Quantum Protocol declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which platform or loader does The Quantum Protocol support?

NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for The Quantum Protocol?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

How do I install The Quantum Protocol?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download The Quantum Protocol safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from CurseForge, where the author last updated it on 21 Jun 2026. We do not host files or republish descriptions. Available download links point to the author’s own release.

Not indexed yet. Score 51 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
