Blockchain 50/50 Raffle
ETH5050 uses blockchain technology to make 50/50 raffles more fair, more transparent, and more accessible than ever. Smart contracts deployed on Ethereum Layer 2 networks handle every aspect of the raffle lifecycle — from ticket sales to winner selection and instant prize distribution.
How Blockchain Technology Powers ETH5050 Raffles
The blockchain is more than just a ledger — it's the enforcement layer that makes 50/50 raffles genuinely trustworthy. When a raffle is created on ETH5050, a new smart contract is deployed to an Ethereum L2 blockchain. This contract contains all the rules of the raffle encoded directly in code: the ticket price, the total supply, the end time, and the 50/50 payout formula.
Once deployed, the contract cannot be modified. No one — not the creator, not ETH5050 — can change the rules mid-raffle or alter the outcome. The blockchain's immutability is the guarantee. When the draw happens, the result is determined by on-chain state that no single party controls, producing a winner that is provably fair and resistant to manipulation.
Smart Contract Security
ETH5050 contracts are audited and immutable. Once a raffle is deployed, the code cannot be changed — by anyone.
Blockchain Immutability
Every ticket and transaction is written permanently to the blockchain. There is no "undo" — the history is complete and unalterable.
Ethereum L2 Speed
Blockchain raffles on Layer 2 networks finalize in seconds, not minutes. Low gas makes tickets accessible to all participants.

The Blockchain Stack Behind ETH5050
Ethereum Compatibility
All ETH5050 contracts are EVM-compatible, running on the same virtual machine as Ethereum mainnet — battle-tested and widely audited.
Layer 2 Scaling
Deploying on Base, Optimism, Arbitrum, and Linea brings Ethereum security at L2 speed and cost. Ticket transactions cost fractions of a cent.
Open-Source Contracts
ETH5050 smart contracts are publicly visible on each network's block explorer. Any developer can read, audit, and verify the logic independently.
No Upgradeable Proxies
Raffle contracts are not upgradeable proxies. What you see when a raffle is created is exactly what runs — forever. No backdoors.
