Seed rotation
Replacing the active server seed with a new one, which reveals the old seed so its bets can be verified.
Seed rotation (or changing the seed pair) ends the current server seed and starts a new one. When that happens the casino reveals the old server seed and shows you the hash of the next one.
Why rotation must come before reveal
A server seed can only be revealed once no more bets will be made with it. If you could see the active seed, you could compute future results. So you cannot verify bets until you rotate. This is by design, not a flaw.
When to rotate
- Before you start a new session, set a new client seed, which usually rotates the server seed.
- When you want to verify a set of bets, rotate and use the revealed seed.
- If you are unsure whether you recorded the hashed seed, rotate and start again with a fresh commitment you have noted.
Worked example
You play 500 bets on server seed A. You click rotate. The casino reveals seed A, shows the hash of seed B, and resets your nonce to 0. You can now verify all 500 bets on seed A.
