Abstract
Embodiments of the invention are systems and methods for computer game tournaments using digital assets stored in a digital asset wallet, comprising: a multiplayer system on a middleware server, wherein a single-player computer game on a computing device uses an application programming interface to communicate with the multiplayer system and to become a multiplayer game; a core system on a middleware server, wherein the core system manages computer game tournaments for the computer game on the computing device; a database server, wherein the database server stores information for the multiplayer system and the core system; and a smart contract, wherein the smart contract is deployed on a blockchain and the smart contract stores digital asset balances for users.
