WorldSign

No. Your room file is never stored. It is held in memory only for the seconds it takes to process, and then it is gone. Nothing is written to disk, nothing is kept in a backup, and there is no copy of your room anywhere on this server.

The signed file you download is kept for 15 minutes so you can download it, and is deleted after that whether you collected it or not. One download link, one use.

A set of identifiers worked out from your file. Think of it as a description rather than a photograph. From what is stored, your room cannot be rebuilt, viewed, or handed to anyone, and there is no way back from it to anything you built. It is only enough to recognise your room again if it turns up somewhere else.

Alongside it: the title and author name you typed, the date, and the labels you gave the copies you handed out.

It stays a working .world file, and it looks and plays exactly as it did before. Nothing is added and nothing is removed. A signed room has been loaded in 3DXChat, edited, and saved again with no trouble at all.

Your original is not touched. The signed file is a separate copy.

It is the private half of your signature, encrypted with the server's key and with your passphrase on top. Two things need it, and nothing else can do either. One is handing the room over for good, which gives you your original file back. The other is registering an updated build of it.

Losing it does not cost you your proof of authorship, because the registry remembers your room regardless. It only means those two operations are no longer possible for that signature. There is no recovery, by us or anyone; that is what makes it worth having.

Put their file into Verify any world. You will get a plain answer: whether it is your registered room, how much of it is yours, and whether the file can be traced back to a specific copy you handed out.

Show that result to whoever is arbitrating. Anyone can run the same check on the same file and get the same answer. You do not have to be trusted, and neither do we.

If you labelled the copies when you handed them out, usually yes. Each copy is marked differently, so the file itself says which one it came from. The report gives the odds of that pointing at the wrong person, and it will refuse to name anybody at all unless those odds are overwhelming. Naming the wrong person is worse than naming nobody.

If you handed out one copy to everybody, it can prove the room is yours but not who passed it on.

Use Sign an updated world instead, with the new file and the previous .wsig. It joins the same record as a new version, so your whole history stays in one place, and a copy someone took from an older build is still recognised as yours.

Not once you have registered it. After that, any attempt to register your room is refused and told whose room it is. That holds whether they upload it whole, cut it down, strip the marks out of it, or bury it inside a bigger file.

Before you have registered it, nothing can help you: the registry records who was first, so being first is the whole point. Sign a room when you finish it, not when you have a problem.

Honestly: yes, by someone determined enough. Anyone who is willing to damage the file can eventually work the mark out of it. We would rather say so than pretend otherwise.

That is exactly why the registry exists and why it is the part that matters. What it recognises is the thing a thief cannot afford to change, because changing it enough would mean no longer having your room at all. Even with every mark stripped out, the file still matches the record you made first.

No account, no email, no password. You type an author name, which is how you re-sign your own rooms later, so use the same one each time. A contact address is optional and is never shown to anyone verifying a file.

Verification needs nothing at all, no account and no upload of anything of yours.

Three a day from one connection. Signing is slow, heavy work, and the limit keeps the service usable for everybody. Checking files is not limited in any way that a person would notice.

If you genuinely need more than that, for a big handover or a lot of copies at once, ask on Discord.

Release ownership, with the signed .world and its .wsig. You get your original file back, exactly as it was before signing, down to the last byte. The mark is taken out, not painted over.

The registry entry stays. That record is what proves you were first, and removing a mark is about handing over a clean file, not erasing history.

Some connections are refused before they reach the service. A VPN, a Tor exit, or a network in a region that has been shut out will all do it. It is not about you personally and it is not a ban.

Try again from your normal connection with the VPN off. If that is not possible, ask on Discord and we will sort it out.
