Stake.com provide on their site a facility for players to retrieve the original
un-hashed* server seed for their "Stake Originals" games. This in normal circumstances allows a player to verify bets in Stake.com's
Provably Fair process.
The problem is that there is a limited time frame in which a player can obtain the
un-hashed server seed. So if a player for whatever reason is delayed in verifying their bets, the server seed may not be available to them and as a consequence those bets are no longer verifiable or
Provably fair. Stake do not inform the players that there is a time limit on the
Provably Fair process, nor do they specify what that timeframe is.
If Stake.com have imposed a deadline on server seed retrieval, I think it's a reasonable expectation that players be informed that there is a restriction on server seed retrieval and what that restricted time frame is exactly.
Personally I think when a player changes seed, the original server seed should be published in their bet archive. Then Stake's
Sometimes Provably Fair can be just provably fair.
*It's not currently possible to un-hash a server seed as sha256 encryption is one way. However I use the term un-hashed here as it is the term Stake.com use on their website.https://stake.com/provably-fair/server-seed-unhash
