Abstract
Decentraland is a virtual reality platform powered by the Ethereum blockchain. Users
can create, experience, and monetize content and applications. Land in Decentraland
is permanently owned by the community, giving them full control over their creations.
Users claim ownership of virtual land on a blockchain-based ledger of parcels.
Landowners control what content is published to their portion of land, which is
identified by a set of cartesian coordinates (x,y). Contents can range from static 3D
scenes to interactive systems such as games.
Land is a non-fungible, transferrable, scarce digital asset stored in an Ethereum smart
contract. It can be acquired by spending an ERC20 token called MANA. MANA can also
be used to make in-world purchases of d...

Introduction
Decentraland provides an infrastructure to support a shared virtual world, also known
as a metaverse
2
. It consists of a decentralized ledger for land ownership, a protocol for
describing the content of each land parcel, and a peer-to-peer network for user
interactions.
1.1
Rationale
The development of large proprietary platforms, such as Facebook, has allowed
hundreds of millions of users to gather, interact, share content, and play games. Their
network effects helped cultivate vast online communities and gaming companies.
These platforms, controlled by centralized organizations, manage the network’s rules
and content flow, while extracting significant revenue from the communities and
content creators who drive traffic to the platforms. Decentraland aims to establish a
network that allows its content creators to own and capture the full value of their
contributions.
The current team began working on Decentraland in 2015. At the time,...

More centralized solutions can work today
7
, although at the expense of operability
with other systems, privacy, and standardization. Decentraland is built on the premise
that low cost, direct payments between content creators and users will radically
change internet commerce.
1.2
History
Decentraland began as a proof of concept for allocating ownership of digital real estate
to users on a blockchain. This digital real estate was initially implemented as a pixel on
an infinite 2D grid, where each pixel contained metadata identifying the owner and
describing the pixel's color. The experiment was entitled Decentraland’s Stone Age.

visual representation of
the blockchain state.
Users could mine,
transfer, and change the
color of pixels they own.
In late 2016, the team started developing the Bronze Age, a 3D virtual world divided
into land parcels. The owner of each parcel was able to associate it with a hash
reference t...

The next version of Decentraland, the Iron Age, will create a social experience with an
economy driven by the existing layers of land ownership and content distribution. In
the Iron Age, developers will be able to create applications on top of Decentraland,
distribute them to other users, and monetize them.
The Iron Age will implement peer-to-peer communications, a scripting system to
enable interactive content, and a system of fast cryptocurrency payments for in-world
transactions. A communication layer is essential for social experiences, providing
positioning, postures, voice chat, and more; Decentraland achieves this with a P2P
network. The scripting system is the tool that landowners will use to describe the
behavior and interactions of 3D objects, sound, and applications running on land
parcels. Finally, a payment system with low fees is key to developing an economy in
the quick environment of a virtual world.
1.3
A Traversable World
The adjacency of land makes Decentraland par...

For services to be provided on Decentraland, we are developing a scripting system that
enables developers to program the interactions between users and applications. This
scripting system runs exclusively on the client side but allows for different data flow
models: from mere local effects and traditional client-server architectures, to P2P
interactions based on state channels. Developers programming in it will benefit from
the availability of fast, cheap micropayments, provably fair games, decentralized
storage, and other features enabled by the advent of cryptographic techniques using
blockchain-based smart contracts.
To foster the exchange of virtual goods, economic incentives must be in place to
ensure the continued creation and distribution of avatars, items, and scripts. Because
static content can be arbitrarily copied, the user experience should empower social
agreements that recognize original creations. By implementing an identity system to
establish authorship, users will be able to tra...

Social
Groups that currently gather in online forums, chat groups, or even other centralized
multiplayer games could port their communities into Decentraland. Offline
communities could also find in Decentraland a space to gather.
Other use cases
There are no technical specifications to what could be built in Decentraland.
Therefore, other use cases could emerge, such as training and professional
development, education, therapy, 3D design, and virtual tourism, among others.
02
Architecture
The Decentraland protocol is comprised of three layers:
1) Consensus layer:
Track land ownership and its content.
2) Land content layer:
Download assets using a decentralized distribution system.
3) Real-time layer:
Enable users’ world viewers to connect to each other.
Land ownership is established at the consensus layer, where land content is
referenced through a hash of the file’s content. From this reference the content can be
downloaded from BitTorrent or ...

Decentraland Roadmap

1
June 2015
Stone Age
Land is modeled as simple grid, and a Bitcoin-like proof-of-work algorithm is used to allocate pixels to users.
2
March 2017
Bronze Age

Land is modeled in a 3D space. Blockchain and torrent full node. World Editor. Unity Browser.
3
August 8 through 16, 2017
Mana Token Sale

An ERC20 token, MANA, will allow users to claim parcels of LAND and interact with each other within Decentraland.
4
Q3 2017
Terraform Event

The first opportunity to claim land will take place, along with the Beta launch of the Iron Age.
5
Q4 2017
Iron Age

Add multiplayer support with avatars and live chat. Allow custom items and scripting on the land you own.
6
2018
Silicon Age

A full-fledged 3D world, with full VR support and customization of the laws of physics. Live in the blockchain.
