Checking Rainbet Results With Seeds and a Nonce
With provably fair, a player can confirm that the outcome was set before the bet went in and did not shift with the amount staked. The seed method applies to most Originals.
Three values to know
| Value | What it is |
|---|---|
| Client seed | A string set by you, which you can change whenever you like |
| Server seed | Created by the server. Until the bet is made, only its hash is visible |
| Nonce | A counter that begins at 0 and goes up by one for every bet on the same seed pair |
Sequence is what matters here. The server seed goes out as a hash before the bet, which means it cannot be altered after the result is known. Once you rotate the seed pair, the original seed is revealed so you can compare it.
Step by step
- Go to the Fair Play tab inside an Original to see which seeds are active. The server seed appears as a hash.
- Make a bet.
- Rotate the seed pair, and the server seed that was used until then is revealed.
- From the Bets screen, open the bet you wish to check.
- Follow that bet's Provably Fair link to see the values it used.
- Compare them in the Verify tab or with the algorithm published for the game.
Games that get randomness from a blockchain
According to Rainbet itself, Case Battles and EOS Roulette draw their randomness from EOS blockchain blocks — public events that nobody can predict beforehand — which places the source outside the platform.
The rest of the games
Rainbet states that slots and live games are run by their providers on random number generators audited by independent laboratories. Verification works differently for them. The list of Originals is on Rainbet Originals.
Frequently asked questions
What is proven by provably fair?
That the outcome was set before the bet went in, and did not shift with what or how much you staked.
At what point does the server seed become visible?
Until the bet is made, only its hash is shown. Once you rotate the seed pair, the original is revealed, so earlier bets can be checked.
Is it possible to change the client seed?
Yes, whenever you like. The player sets this value.
Can slots be checked in the same way?
No. Rainbet states that slots and live games use independently audited random number generators. Checking on the player's side applies to Originals.
