With the rise of blockchain technology and the advent of play-to-earn models, Card games have evolved into dynamic ecosystems where players can not only engage in gameplay but also earn real-world value. The first chapter focuses on the design aspects of blockchain-based ecosystems specifically for Dawnshard, a unique deck Card Game. It delves into the core principles of creating an immersive and rewarding player experience. Various factors such as game mechanics and balance are examined to ensure an engaging environment for players.
