After the game ends, how do players verify whether the server seed used for the current round matches the promise made before placing the bet?
The 28BET Hash Seed Game follows a process of "publishing hashes before betting and providing used seeds after settlement," allowing players to check game results and verify seed records themselves.
What is the SHA-256 Seed Pre-Disclosure?
SHA-256 can be understood as generating a digital fingerprint for data. The same content is computed in the same way to obtain the same hash value. The output of SHA-256 is 256 bits, usually displayed in 64 hexadecimal characters. Technical Description
At 28BET, the process is divided into three stages:
- Before Betting: The system provides the SHA-256 hash for the server's seed, but the seed itself has not yet been disclosed.
- After settlement completion: Players can obtain the server seed they have used through the in-game verification feature.
- Self-Check: Recalculate the seed's SHA-256 and compare it with the hash saved before betting.
The key point of verification is: **Based on the hash saved before the note below, not just comparing the two strings of data obtained simultaneously after settlement. **
Method 1: Use 28BET "Match Seed Verification"
Before placing a bet
View and save the full SHA-256 hash pre-published by this bureau. You can copy the text or take screenshots for retention, and also record the client seed.
After completing the settlement
- Initiate 'Bureau's seed verification.'
- Check the "SHA-256 saved before betting", client seeds, and nonces.
- Click "Check Seed."
- After successful verification, the screen will display "Seed matches the pre-bet hash" and provide the server seed you have used.
If you need to conduct further self-checking, you can use the manual method below.
Method 2: Calculate SHA-256 yourself
Prepare the following two complete documents:
- SHA-256 cache saved before betting.
- The 'Used Server Seed' obtained after settlement.
In the SHA-256 calculation tool, select text input/UTF-8 mode, paste the complete used server seed, and then compare the calculation result verbatim with the previously saved hash.
The correct way to check is:
SHA-256 (UTF-8 text for the full server seed)
= SHA-256 saved before betting
Please note when calculating:
- Enter only server seeds; do not add client seeds or nonces.
- Do not add spaces, line breaks, quotation marks, or separators.
- Do not use hexadecimal decoding mode; Even if the seed appears to be a hexadecimal string, it should still be treated as text input.
- Do not use data containing "......" or that is cut off by the screen.

You can also run the following command on the terminal to replace the prompt text in quotes with the full used server seed:
printf '%s' 'Paste the complete used server seed' | shasum -a 256
The first 64 characters of the output are the calculation results. 'printf '%s'' does not add extra line breaks, which helps avoid common check-up differences.
Why does Nonce show as 0?
28BET currently uses a brand-new server seed per round, so Nonce is fixed at 0. It represents the serial number within that seed, not the total number of games played by the account.
Client seeds and Nonce are part of this bureau's records, but when checking the "pre-published hash of server seeds," they do not need to be concatenated.
What Does Successful Verification Mean?
Successful verification means the obtained server seed matches the hash promise saved before the bet.
It is important to distinguish: ** Seed consistency verification does not equate to reproducing the complete game result or verifying the entire payout algorithm. ** SHA-256 is also not blockchain proof; successful verification does not guarantee winning or profit.
If the verification is inconsistent, please first check whether the information is complete, whether you have selected the wrong game number, and whether the input mode is correct. If you still have questions, keep your game position number, pre-betting hash, and verification screen, then contact customer service for verification.
