Right now? It's a 2D grid of tiny pixels up for sale. Each pixel represents a parcel of LAND (a scarce, non-fungible digital asset) that you can buy using MANA (an finite supply ERC-20 token). But by Q4 2018 (the "Silicon Age"), Decentraland will feature a 3D rendered, distributed VR world. You'll be able to create 3D scenes, content, and applications on your LAND, and monetize them. Casinos, music venues, businesses, underwater architecture – anything you can build. The world will be shared through multiplayer support with avatars and live chat.
Ok, hold your horses; like we said, as of July 2018 the full 3D VR experience is still under development. However, you can head over to the Decentraland marketplace (market.decentraland.org) right now to browse for 10m x 10m LAND parcels, identified by coordinates (x,y), and buy with MANA. Devs recommend connecting and unlocking a MetaMask or Mist account before using the marketplace. Ledger hardware wallets are also an option (you'll need browser support). You'll find a more complete tutorial https://docs.decentraland.org/decentraland/marketplace/ here
This game is very true to its democratic principles. For example, some parcels are organized into Districts, themed communities based on similarity in use and interests of the owners. The themes of the Districts were actually the result of a community vote! You can find a list of the original District Proposals on GitHub.
When Silicon Age launches, you'll be able to create anything from static 3D scenes and audio to more interactive applications or games, and monetize them. The content on Decentraland will be stored and distributed via the IPFS network, while data hashes (ownership and transactions) are validated on the Ethereum blockchain. The 3D world will be accessible from mobile devices, web browsers and VR headsets.
To prepare for the Silicon Age, study up on the technical aspects of Decentraland with their friendly documentation at https://docs.decentraland.org/.
· Decentraland will deliver the first ever decentralized VR world. · The community will have full control over the content and economy of the metaverse. · You can buy LAND (non-fungible assets) with MANA (ERC-20) tokens. · You'll be able to monetize the goods and services you create in the 3D world.
