Every online crypto roulette bet produces a log, but the location and accessibility of that log vary by platform type. On fully on-chain platforms, each bet writes a permanent transaction to the public blockchain at the moment it is placed. The platform does not hold that record. It exists on the ledger independently, readable by anyone with the wallet address. On centralised platforms, the log lives inside the platform’s own database, visible only through the account interface the platform provides.
What information does each bet record contain?
On-chain bet records contain the wallet address, a unique transaction hash, the block timestamp, the wagered amount, and the contract function called. That last element is particularly useful on platforms where bet type and selection are encoded into the contract interaction, because it means the specific wager placed is part of the permanent record rather than just the amount.
Centralised platform logs capture more game-level detail. Round identifiers, outcomes, balance changes before and after each bet, and server-generated timestamps are all typically present. The trade-off is that none of this data sits outside the platform’s control. Its accuracy cannot be verified independently, and its availability depends entirely on the platform’s continued operation and willingness to provide access.
Where do bet logs live across different platform types?
- On-chain platforms store every bet as a discrete blockchain transaction. The full session history is reconstructable from the wallet address alone, without logging into the platform or requesting any data from it.
- Hybrid platforms divide the record. Deposits and withdrawals appear on-chain while individual bets are stored internally. A complete picture of a session requires checking both the blockchain and the platform’s own history section, because neither source alone covers everything.
- Centralised platforms keep the entire log internally. The blockchain shows only the deposit that funded the session and the withdrawal that followed it. Nothing in between leaves an on-chain trace regardless of how many bets were placed or how long the session ran.
- Live dealer formats on centralised platforms sometimes add a visual layer alongside the numerical log. Round recordings give a reference point for each outcome that pure data logs cannot provide, which can matter when a dispute involves the physical result of a spin rather than a processing error.
What does the log mean when something goes wrong?
When a bet outcome is disputed, the type of log available determines what evidence exists and who controls it.
An on-chain log is neutral ground. Both the player and the platform see the same immutable record. Neither can alter it, and neither needs the other’s cooperation to access it. The transaction hash, timestamp, and wagered amount are fixed from the moment the block was confirmed, and a block explorer retrieves them without any platform involvement whatsoever.
A centralised log places the player in a dependent position. The platform presents its own records during any dispute, and the player has no external source to cross-check them against. Most platforms operate with accuracy and good faith, but the structural limitation remains regardless. The absence of an independent reference means the resolution of any dispute rests on the platform’s records being both complete and honestly presented, rather than on data that neither party can manipulate after the fact.
