Libera

Libera is a gaming platform on zkSync Era and Scroll that aggregates free and paid browser games, letting players discover titles, compete, collect items and sell them on a marketplace under one account. The platform token settles market trades and tournament entries, publishers set their own item output and pricing, and items belong to players on-chain.

Fairness rests on verifiable randomness: before each round the user seed, server seed and a nonce are hashed into a commitment, the server seed is published afterwards, and a player can recompute the hash to confirm the outcome was untouched. Randomness also draws on Chainlink VRF and Pyth entropy, with models watching the output distribution for anomalies. A developer console handles listing, tuning and retention data. Games pass a listing review and must describe how items are produced and settled before they appear, which lets players read the economic structure up front.
