Xaya

Xaya is a blockchain-based platform designed to host decentralized, provably fair online games. It provides a framework for developers to build games where most of the game state and outcomes are recorded on a public blockchain, enabling players to verify results without relying on a centralized server.

Technically, Xaya employs a separation between game logic and game state, allowing multiple games to run atop a shared security layer. Game actions are submitted as transactions, and the consequential state transitions are anchored in the blockchain. The design emphasizes determinism and verifiability, with mechanisms to prevent cheating and to prove fairness.

Xaya supports a range of game types, from board and strategy games to more complex multiplayer titles. It promotes open-source development and community governance, with developers able to publish games and players able to contribute to the ecosystem. The native asset is used to pay for on-chain resources and incentivize participation, while community members can vote on governance proposals.

History and reception: The project emerged in the mid-2010s as part of the blockchain gaming movement, with ongoing development and occasional milestones such as testnet launches and partnerships. The user base remains relatively small compared to mainstream gaming, but Xaya is cited in discussions of on-chain game state and provable fairness as an early approach to decentralized gaming platforms.
