# How Do We Ensure Fairness in Penny Win?

At Penny Win, every winner is chosen using a transparent and tamper-proof process. Here's how it works:<br>

1. **Track Participation Times:** When a product is about to be allocated, we take the timestamps of the last 10 participation entries (or all entries if there are fewer than 10). These are turned into numbers and added together.
2. **Blockchain Fairness:** To add randomness, we wait for the next Ethereum block after the final participation. The block's hash value is converted into a number, ensuring no one can predict it.
3. **Final Winning Number:** The two values (timestamps and blockchain hash) are combined. The sum is divided by the total participants to get the remainder, which determines the winner.
4. **Guaranteed Transparency:** Every step uses publicly verifiable data, making the process truly fair.
