Individual wagers follow a detailed path from when a player starts a bet to when the outcome is delivered. Each bet passes through several processing stages involving interface actions, blockchain operations, and automated calculations. Blockchain-based lottery games carry out bets through coordinated steps across distributed systems. Ethereum Keno wagers travel from player devices to platform servers and then to smart contracts before results return. Every stage has unique timing and processing needs that affect how quickly bets finish and payouts reach players.

Number selection submission

Players initiate bets by choosing numbers through interface elements that highlight selections visually. The selected numbers are stored temporarily in the browser memory while players finalise quantity decisions and review their picks. Submission happens through dedicated buttons that package selection data alongside stake amounts into transaction requests.

The interface constructs bet objects containing all necessary information for processing. These data structures include player addresses, selected number arrays, wager quantities in ETH, and timestamps. The formatted bet data transmits to platform servers that validate completeness before forwarding to blockchain layers for permanent recording.

Wallet approval process

Ethereum transactions require explicit wallet authorisation before execution. Players receive prompts from wallet software requesting permission to broadcast bet transactions. These approval interfaces display transaction details including gas fees, destination contract addresses, and data payloads representing bet parameters.

• Gas price selection determines transaction priority.
• Spending limit confirmation for token approvals
• Transaction data verification showing the bet contents
• Nonce values ensuring proper transaction ordering
• Signature generation proving wallet ownership

The approval step introduces player control over transaction finalisation. Rejecting prompts cancels bets without consequences, while approving initiates irreversible blockchain submission. The explicit consent mechanism protects against unauthorised transactions while adding interaction friction that some players find cumbersome.

Smart contract reception

Approved transactions are broadcast to Ethereum network validators who include them in upcoming blocks. Smart contracts monitor their addresses and detect incoming bet transactions during block processing. The contract logic parses transaction data, extracting bet parameters and player information needed for outcome generation.

Contract code validates received data against game rules. Bet amounts must meet minimums, selected number quantities must fall within allowed ranges, and player addresses must maintain sufficient balances covering wagers fees.

Random generation execution

Successful validation triggers random number generation within smart contract environments. The contracts employ verifiable randomness sources combining blockchain data with oracle inputs or commit-reveal schemes. These mechanisms produce unpredictable outcomes while maintaining verifiability that prevents manipulation. The generated random values map to keno ball selections through modulo operations or similar distribution algorithms.

Outcome determination logic

Contract code compares player-selected numbers against generated draw results. Match counting algorithms identify intersections between the two sets, tallying how many player choices appear within drawn numbers. The count determines which paytable entry applies for payout calculation. Predetermined multiplier tables embedded in the contract code specify returns for each match scenario.

Payout distribution sequence

Calculated payouts trigger automated token transfers from contract reserve pools to player addresses. The smart contract executes these transfers atomically within the same transaction, processing the bet, ensuring immediate settlement without separate payout operations. Winners receive funds directly to their wallet addresses without requiring additional claims. Failed bets are complete without payout transfers, simply recording outcomes without balance modifications beyond initial wager deductions.
