About Decentraland
Decentraland is a pioneering virtual world where the boundaries of imagination and technology blend seamlessly. Built on the Unity engine, our platform streams and renders a vast, continuous environment filled with diverse, user-generated content. As avatars explore this immersive landscape, they encounter new creations daily, from games and puzzles to scenes and artworks—all crafted by our vibrant community of creators.
Our platform goes beyond traditional gaming experiences. Users can attend live music events, conferences, exhibitions, dance parties, and more, all within a richly detailed metaverse. Decentraland started as a proof-of-concept for digital real estate ownership on the blockchain but has evolved into an ever-expanding world where anything is possible. Join us as we continue to push the boundaries of what a virtual world can be.
