A Decentralized Approach to Award Game Achievements.

Blockchain technology allows players to own in-game assets and to be rewarded with NFTs or tokens for their game achievements, thus can be a game changer for all the gaming industry. One central issue is how to check that conditions for achievements are met (e.g., that the player completed level 10). Current approaches open cheating backdoors (e.g. if the client checks the conditions) or introduce centralization points (if a backend checks the condition). Ideally, we would like to “run” games on chain, but so far that has not been possible due to the high computational cost, especially on Ethereum; however, the development of technologies like proofs of computation can solve this problem. Being able to run games on the blockchain, new decentralized rewarding systems can be built to ensure the fair and transparent rewarding of game achievements.
