# Raffle FAQ

## Is It Really Random? 

Capybara uses Pyth Entropy for blockchain Random Number Generation (RNG), which generates truly random numbers through a secure commit-reveal process. Two parties create secret numbers, commit them on-chain, then reveal and combine them with the blockchain’s blockhash for extra unpredictability. This ensures randomness is completely secure, tamper-proof, and fair for all users. For more information, check out [Pyth Entropy](https://www.pyth.network/blog/pyth-entropy-random-number-generation-for-blockchain-apps).

## Where is the Prize from?

Prizes for each lottery round come from two sources:

* Ticket Purchases: 90% of the Kaia spent on tickets goes into the prize pool, 10% goes to the treasury.
* Rollover Prizes: If no one wins in a prize bracket, the unclaimed Kaia rolls over to the next round and is redistributed among the prize pools.
