BIT5050 On-Chain Raffle Protocol
On-Chain Raffle — BIT5050
An on-chain raffle is a specific technical claim. It means every entry is a blockchain transaction. It means the draw executes via smart contract using verifiable on-chain randomness. It means the payout is recorded on a public ledger — permanently, immutably, auditable by anyone with a block explorer.
BIT5050 is the on-chain raffle protocol that delivers all three. Live on 15+ blockchain networks, with no off-chain components in the draw path, no operator custody over funds, and no human trigger required to execute. The contract runs. The chain records it. Anyone can verify it.

The Technical Standard
What Is an On-Chain Raffle?
An on-chain raffle is a raffle where every critical function — ticket entry, winner selection, and prize distribution — occurs as a verifiable transaction on a public blockchain. Nothing happens off-chain. There is no server, no backend database, and no operator logic that participants cannot inspect.
The phrase "on-chain" is the most precise technical qualifier for a blockchain raffle. It distinguishes protocols where the draw genuinely executes on the blockchain from hybrid systems that accept entries on-chain but resolve the draw via a centralized server, an off-chain random number generator, or an admin account that must manually trigger the payout.
On BIT5050, the distinction is complete. This is what a genuine on-chain raffle means. BIT5050 is built to this standard on every chain it deploys on.
Entries are on-chain
Every ticket purchase is a blockchain transaction with a transaction hash. The entry is immutable from the moment the block confirms.
The draw is on-chain
When raffle conditions are met, the smart contract triggers the draw using entropy derived from blockchain state. No API call. No server. No oracle dependency. The blockchain is the source of truth.
The payout is on-chain
The winning wallet receives funds in the same transaction as the draw. The transfer is recorded on-chain. The result cannot be reversed or disputed.
Verification is public
Anyone — participant, observer, regulator, or auditor — can look up any BIT5050 draw on any block explorer and verify the entry list, the randomness seed, the winner selection, and the payout. No permission required.
Three Verifiable Phases
How BIT5050's On-Chain Raffle Works
The BIT5050 on-chain raffle protocol operates through three verifiable phases. The entire lifecycle of every BIT5050 on-chain raffle is a sequence of public blockchain transactions. There is no moment in the process that occurs off-chain, on a server, or in a private database.

Entry Phase — Every Ticket Is a Transaction
A raffle creator deploys a BIT5050 smart contract on any supported chain. The contract address is public. Any wallet can send the required ticket amount to the contract. Each send is a blockchain transaction: it has a hash, a block timestamp, a sender address, and a value. The contract records each entry in its state. The accumulated pot is visible by querying the contract — no dashboard needed, no API call required, just a block explorer and the contract address.
Draw Phase — Executed by the Contract, Verified by the Chain
When the raffle's entry conditions are met — minimum ticket count reached, draw window elapsed — the smart contract executes the draw automatically. The randomness used to select the winner is derived from blockchain state at the time of execution: block hash data, transaction ordering, and accumulated entry entropy combined into a verifiable seed. Any developer can reproduce the calculation from the on-chain data and confirm that the winner selection was mathematically inevitable given the block's state. No server generated it. No operator chose it.
Payout Phase — Automatic, Instant, On-Chain
In the same transaction as the draw, the contract sends 50% of the pot to the winner's wallet and 50% to the raffle creator's wallet. These transfers are blockchain transactions — permanent, public, and irrevocable. The winner receives funds without claiming. The creator receives their cut without requesting. The chain settles the raffle in one atomic operation.

Mathematical Transparency
The 50/50 On-Chain Raffle Model
BIT5050's on-chain raffle uses a 50/50 payout model — the most transparent raffle mechanic available on any chain.
When the draw executes on-chain, 50% of the total pot is transferred to the winner's wallet in the same transaction, and 50% of the total pot is transferred to the raffle creator's wallet, less the protocol fee. Both transfers are on-chain transactions — independently verifiable by anyone.
Winner receives: 50% of total ticket sales
Creator earns: 50% of total ticket sales (less protocol fee)
Both transfers: On-chain, in the draw transaction, irrevocable
The 50/50 split is hardcoded in the smart contract. The raffle creator cannot change it after deployment. The protocol cannot override it. The chain enforces it. At any point during a live on-chain raffle, any participant can query the contract and calculate the exact current prize — 50% of the total entries collected to that moment. No hidden rake. No mystery deduction. The math is on-chain.
The Trust Elimination Argument
Why "On-Chain" Is the Only Standard That Matters for Raffles
The raffle format has a fundamental trust problem: whoever runs the draw controls the outcome. In traditional raffles, you trust the operator. In hybrid blockchain raffles — where entries are on-chain but the draw happens off-chain — you still trust the operator for the most critical step.
A genuine on-chain raffle eliminates this trust requirement from the draw itself. When the smart contract executes the winner selection using blockchain-state randomness, there is no operator to trust. The chain produced the entropy. The contract applied the logic. The result is mathematically predetermined by the block's state — verifiable by any party independently.
BIT5050 holds to this standard strictly. Every raffle on every chain uses on-chain draw execution with no off-chain dependency in the winner selection path. This is not a feature toggle or a premium option. It is the baseline for every on-chain raffle on the BIT5050 protocol.

Frequently Asked Questions
Frequently Asked Questions
What is an on-chain raffle?+
An on-chain raffle is a raffle where every function — ticket entry, winner selection, and prize distribution — occurs as a verifiable transaction on a public blockchain. Nothing is resolved off-chain or by a centralized server. Every step can be independently verified on a block explorer.
How is an on-chain raffle different from a regular blockchain raffle?+
A regular blockchain raffle may accept entries on-chain but resolve the draw via an off-chain server or centralized RNG. An on-chain raffle executes the draw using blockchain-state randomness with the smart contract as the sole executor. BIT5050 uses fully on-chain draw execution with no off-chain dependency.
Which chains does BIT5050's on-chain raffle protocol support?+
BIT5050 is live on Ethereum, Base, Solana, Avalanche, TON, Bittensor, Cardano, Sui, BNB Chain, Moonbeam, Hyperliquid, Polkadot, and more — 15+ blockchain networks on mainnet.
How can I verify the result of an on-chain raffle?+
Look up the raffle's smart contract address on any block explorer for that chain. The draw transaction contains the randomness seed, the winner selection logic execution, and the payout transfers. Any developer can independently reproduce the winner calculation from the on-chain data.
What is the 50/50 mechanic in BIT5050's on-chain raffle?+
The smart contract splits the pot automatically at draw time: 50% goes to the winner and 50% goes to the raffle creator. The split is hardcoded in the contract and enforced by the chain — it cannot be changed after deployment and is visible to any participant at any time.
Do I need a token to run an on-chain raffle on BIT5050?+
No. BIT5050 has no governance token. You run an on-chain raffle using the native currency of your chosen chain — ETH, SOL, AVAX, TON, BNB, and so on.
Is BIT5050 a non-custodial on-chain raffle protocol?+
Yes. Ticket proceeds are held exclusively by the smart contract from the moment of entry to the moment of payout. BIT5050 never has access to participant funds. The contract distributes the pot automatically at draw time.
