# FOS — Blockchain Collectibles Platform > FOS is a decentralized digital art protocol on the Base Network (Ethereum L2). We offer unique digital collectibles (NFTs) with an automated, trustless reward distribution mechanism. ## About FOS FOS replaces traditional centralized intermediaries with transparent, immutable smart contracts. The platform is non-custodial — we never hold user funds. All transactions are executed automatically via publicly auditable smart contracts on the Base Network. ## How It Works FOS operates in repeating cycles called "Cycle of 500": - Each cycle starts with the first mint and ends at the 500th collectible (the "Green Eye") - The 500th mint triggers an automated reward distribution to participants - Recipients are selected via Chainlink VRF (provably fair random number generator) - All logic is on-chain, transparent, and tamper-proof ## Collectible Tiers - **FOS Buddy** — Entry tier (~$3 USD in ETH) - **FOS Samurai** — Mid tier (~$13 USD in ETH) - **FOS Noble** — Premium tier (~$25 USD in ETH) Free gas-only mints are available at specific numbers: #10, #100, #200, #300, #400. ## Key Features - Non-custodial: users maintain full control of their assets - Built on Base Network (Ethereum L2): low gas fees, fast transactions - Chainlink VRF for provably fair randomness - Automated reward distribution via smart contracts - Affiliate program with 82% commission on direct referrals - Growth campaign leaderboard with milestone rewards ## Technology Stack - Blockchain: Base Network (Ethereum Layer-2) - Smart Contracts: Solidity, ERC-721 - Randomness: Chainlink VRF v2 - Price Feeds: Chainlink Price Oracles ## Pages - [Home](https://fos.ooo/) - [Whitelist](https://fos.ooo/app/whitelist.php): Join the whitelist for free mint access - [Free Mint](https://fos.ooo/app/FreeMint.php): Mint collectibles for gas fees only - [Games / Gallery](https://fos.ooo/app/game.php): Browse NFT collectibles - [Roadmap](https://fos.ooo/app/roadmap.php): Development timeline - [FAQ](https://fos.ooo/app/faq.php): Frequently asked questions - [About Us](https://fos.ooo/app/about-us.php): Mission and philosophy - [Documentation](https://fos.ooo/document): Full technical documentation - [Privacy Policy](https://fos.ooo/app/privacy.php) - [Terms & Conditions](https://fos.ooo/app/terms-condition.php) ## Community & Social - Website: https://fos.ooo - X (Twitter): https://x.com/fos_ooo - Discord: https://discord.gg/hUwCxKPRbG - Telegram: https://t.me/fos_telegram - YouTube: https://www.youtube.com/@Fos-youtube - GitHub: https://github.com/fosooo ## Detailed Information For comprehensive content, see: https://fos.ooo/llms-full.txt ## Legal FOS is NOT a lottery, gambling site, or financial product.
