holoholona is a on-chain lottery and gaming platform built on Solana. every draw is trustless: ticket purchases, pool accumulation, winner selection, and prize distribution all happen via open-source smart contracts with no admin keys.

players connect a Solana wallet (Phantom, Solflare, or Backpack), purchase tickets in SOL, and wait for the scheduled draw. winners are determined by a Verifiable Random Function (VRF) — a cryptographic proof that the outcome was random and could not have been predicted or manipulated by anyone.

1. player purchases ticket — SOL is sent to the game's on-chain pool account
2. draw triggers at scheduled time or pool threshold
3. VRF oracle (Switchboard) generates a verifiable random seed on-chain
4. smart contract selects winner(s) deterministically from seed
5. prize SOL is distributed automatically — no claim needed
6. draw record is written to chain: seed, proof, tx signature, winner (anonymized)

holoholona uses Switchboard VRF — Solana's decentralized oracle network for verifiable randomness. each draw produces:

• VRF seed — the random value generated by the oracle network
• proof — a cryptographic proof that the seed is genuinely random and unmanipulated
• tx signature — the Solana transaction that records the draw result on-chain

any player can independently verify any draw on the Solana Explorer using the transaction signature. the draws history page provides a verify link for each draw.
