Libplanet is a .NET library for creating the multiplayer online game in a decentralized fashion, which means the whole gameplay occurs on a peer-to-peer network among equal nodes rather than an authorized central server. Under the hood, it incorporates many features (e.g., digital signature, BFT consensus, data replication) of a blockchain.
It has competitive advantages over other solutions for decentralized gaming:
Embeddable: A game app does not have to communicate with another running process, hence it doesn't require extra marshaling or processes management. To draw a parallel, Libplanet is closer to SQLite than MySQL or PostgreSQL.
Isomorphic: Libplanet is a .NET library, so every game logic can be written in the same language, C#, and run on the blockchain. No glue code or "smart contracts" are needed.
Token-independent: Unlike almost every blockchain system, it does not force users to create and deal with yet-another-cryptocurrency. Your game can be free to play, and enjoyed by regular gamers.
