(Pre ANN) Decentraland A blockchain-based virtual reality world

  • A virtual world that runs on open standards

    Decentraland is an open source protocol to create and explore shared experiences in virtual reality

    Why Decentraland?

    A public virtual world should be ruled by open standards, shielded from the agenda of any central organization.

    In Decentraland, users have full control over the content of the land they own and keep all the proceeds from the value they generate for other users.

    To make this possible, Decentraland uses blockchain technology as an unforgeable record of ownership.

  • Announcing Decentraland’s Genesis City

    How to claim, develop, and monetize your LAND.

    We’re getting close to our token sale on August 8th. The sale will finance the development of Decentraland’s Iron Age, an ambitious milestone that will include:

    1. peer-to-peer network, allowing users to interact.
    2. micropayment system, creating an in-world economy.
    3. land management interface to develop, buy, rent, and sell LAND.
    4. scripting language so landowners can program custom experiences.

    By participating in our token sale, you’ll be able to buy ownership in the first decentralized VR platform. IDC projects the AR and VR markets to grow from from $5.2 billion in 2016 to $162 billionby 2020. Decentraland aims to be a major player in that growth.

    When Can You Claim Your LAND?

    Our ERC20 token, MANA, will be directly exchangeable for LAND. In Q3 2017, we will announce the Terraform Event, after which you can exchange your MANA for LAND.

    Details of Your LAND

    Decentraland is a connected world formed by parcels of LAND. When claiming LAND, there are a few things to note:

    1. Each parcel has an area of 100 square meters (roughly 1,080 square feet).
    2. You can only claim LAND that is adjacent to previously claimed parcels. This improves the value of your LAND as it will be connected with the rest of the world.
    3. You have complete control: only the LAND owner can define the content of their parcel.
    4. LAND ownership is transferable. You can buy, sell, rent, or lease LAND at your will.

    Blockchain Partnerships Give You Flexibility

    We’ve already announced several partnerships with other blockchain platforms, including Aragondisctrict0x,Coral, and more. These partnerships will help maximize the long-term value of your LAND.

    For example, you will be able tomonetize your property through rentals, leases, and sales. To facilitate a secondary market, we’ve partnered with disctrict0x. Their decentralized marketplaces will allow you to manage your LAND as an investment.

    Genesis City

    To encourage development, the Decentraland team is designing a layout for the first metropolis: Genesis City.

    A fraction of the raised funds will be used to allocate plots as public spaces, streets, parks, landmarks, and other value-add spaces. We are incorporatingideas and feedback from the community to help determine the final layout of the city. Afterward, artists and creatives will be invited to populate these spaces.

    The community is already hard at work. Check out our Github repository to pitch your own ideas and see what’s already been suggested.

    A proposal from the community for a city-wide transportation system.

    Building Communities

    Districts and neighborhoods will naturally form around shared interests. For example, an ‘Entertainment District’ might include VR theaters, live musical performances, arcades, racetracks, and casinos. Organizations like the Voltaire House are looking to create shared workspaces, potentially leading to a ‘Business District’.

    We have already received interest from multiple communities and organizations that want to develop LAND within Decentraland. To accelerate adoption prospective communities looking to transition to Decentraland will be aided in this process.

    Next Steps

    We’re building Decentraland to give users and developers what they really want: full control. Our token sale is an exciting opportunity to buy into the exponential growth of VR. We’ll see you in the metaverse!

  • Decentraland  New Token Sale Date: August 17th 

    The Decentraland token sale has been rescheduled to ensure complete regulatory compliance

    A few major blockchain events have taken place over recent weeks. On August 1st, Bitcoin experienced a hard-fork, giving birth to Bitcoin Cash. Separately, the SEC provided much-needed guidance on token sale regulation.

    After thoroughly reviewing the latest regulatory announcements, we’re reassured that our MANA token is not a security. We take regulatory compliance seriously, and are allocating some extra time to consult with our legal teams. We’ve revised our token sale dates to reflect these extra measures.

    Our amended crowdsale schedule now begins on August 17, 5:00 PM PST / 8:00 PM EST in the US, August 18, 1:00 AM in the UK, and August 18, 8:00 AM in China. All other details of the crowdsale will remain the same.

    During the extension period, Decentraland will continue to actively work with advisors and legal entities to ensure we maintain complete regulatory compliance.

    We appreciate the community’s patience, understanding, and overwhelming support as we continue to build Decentraland into a truly shared, decentralized virtual reality world.

  • Decentraland Reaching a wider audience

    Doing our best to let as many people participate as possible.

    The past two months have been pretty hectic for the Decentraland community. We’ve had the pleasure of meeting and working with amazing people along the way, and a very strong community has come together to give birth to the open metaverse. We’re left speechless by the public reception of our project, and we couldn’t feel more grateful.

    Last week we decided to give our community the ability to guarantee their spot in our token sale by creating a Community Whitelist. Once again, the support reflected in this initiative blew us away. Over a thousand community members signed up.

    An aggressive phishing attack started making the rounds throughout our community, which led us to cancel the whitelist as a preventive security measure. It was a tough decision, but our community’s safety remains our top priority.

    What became clear is that the community’s intention to contribute is stronger than expected. A significant amount of people from our community reached out to communicate their worry about not being able to make it on time for the sale.

    We are humbled by the global demand for MANA and, in the spirit of launching our virtual world with the widest audience possible, we intend to let as many people participate as possible. This is why we have decided to increase the hard cap by $5M. While not a guaranteed solution, this significantly increases the community’s chances of securing some tokens.

    Those who signed up to the Community Whitelist will be guaranteed the 40% discount corresponding to the first block of the sale, regardless of when they contribute.

    We hope to see you when the token sale starts on August 17th at 8pm EST.

    Once again, we appreciate the community’s overwhelming support as we continue building Decentraland.

  • Decentraland Dev Update - Terraform Auction Updates,Product Plan & More Updates

    Terraform Auction, Decentraland Editor and an alpha Web Client.

    October was a great month at Decentraland. It started off with the addition of Ben Nolan to our Dev team after the launch of the Terraform Registration app. Last week, we published the alpha version of our A-Frame-based parcel editor and on-boarded another great engineer: Michal Takac. Finally, we presented our project progress at the San Fransico WebVR/AR Meetup and got our MANA token listed on various exchanges.

    November is looking to be even more exciting!

    Terraform Auction Updates

    One of the most important projects we’ve been working on is the Terraform Auction. We are looking forward to seeing how the initial land plots will be distributed and are excited about what kinds of experiences people are getting ready to build in Genesis City. The expectations are high, which is why we’ve been working to build a strong foundation to power the auction.

    The auction will be conducted through an off-blockchain process with the goal of saving on gas costs and avoiding potential confirmation issues. For each bid received, we’ll issue a receipt that will be cryptographically signed and have a sequence number. This will allow everyone to check that their submission was correctly included in the final result. The application will be open source, and the process independently verifiable: we will publish the database contents so that anyone can replay each step of the auction and verify the process.

    We are in the process of finishing up the design of its user interface, and are planning to have it ready by mid-November. If everything goes as expected, we intend to conduct a dry-run of the auction by November 20th. Stay tuned for more details!

    Governance and Districts

    We are also discussing and working on the design of decentralized governance methods for the districts. We are currently gathering feedback on what district participants need: some issues include governance models and dApps for ruling over content or land ownership, among others. Given the early stages of decentralized governance tech, a more centralized approach is our inevitable fallback: for the time being, districts will centralize decisions on an individual or group of district leaders. We will publish a guide on how district leaders can use a multisignature wallet to own and control their parcels.

    Another exciting project in the works is the review of the first smart contract that interacts with our LAND smart contract. This will facilitate a way for people to lease land and was contributed by Alonzo Coeus. Districts may also use this work as the base layer to enable their members to modify only the content on parcels assigned to or owned by them, yet allowing the district to take back control of the parcel, in case it is not aligned with the district’s purpose.

    Product Plan and Updates

    Launching the alpha version of the editor is the first of four steps towards having an alpha version of the Decentraland Iron Age.

    We are already uploading content to IPFS. The next step is to publish the information on the LAND contract, following the DSP20 parcel spec.

    Our next step is to work on making the Decentraland Editor publish content to the Ethereum network, by registering it on the LAND smart contract we’ve been working on.

    The third and fourth steps concern updating the client to load data from IPFS/IPNS, and have it work in sync with the LAND Smart Contract. We will be starting to use the Decentraland Specification Proposal #20, regarding the format required to fully describe a land parcel’s content.

    If all of this goes smoothly, then an alpha version of the Iron Age will be up and running by December. At that point, the pioneers of Decentraland will be able to start working on their parcels. All in all, we’re pretty close to having a fully functional prototype with which we can already start building!

    As a final note, we want to thank all of you who helped us through this process, especially to those involved in building the districts! We are very glad this is all coming together and we hope to see you soon in the metaverse.

    Remember that you can stay in touch with us through:

  • Decentraland Dev Update- Terraform Registration, Web Client and Editor, EthAlarm , Genesis City Auction & More

    Terraform Registration

    Users can now use their Ledger hardware wallets to participate in the Terraform Registration and stake MANA to either the Genesis City auction or one of the many community districts. We also fixed a recurring problem that led to transactions not being accounted for. Finally, we are about to finish a feature that will enable advisors, early contributors, and the team to use their vested tokens in the Terraform.

    Genesis City Auction

    Our team began the testing process for the land auction web app (which is being deployed to the Ropsten testnet network soon!). We will be releasing the source code and starting with the security audits next week.

    Web Client and Editor

    We’re at the final stage of integrating the web client with the scene editor. This is our top priority, as it will allow early users to start experimenting with creating and uploading content to [testnet] land. Our goal is to release early and nourish ourselves from everyone's feedback to iterate fast.

    Additionally, we have fixed some performance issues and added new features to the editor, such as uploading objects directly from Google Poly, experimental support for editing directly in VR,

    , among others.


    The response to EthAlarm was outstanding, and we are looking into ways to make this dApp more scalable. Thus, we’re temporarily taking down the public instance of EthAlarm to improve its performance and reliability.

    District Governance Framework

    We are working with District leaders to help organize, develop and deploy district projects. Currently, we are building out a District Governance Framework that will act as a preliminary guide in which the roles and responsibilities of district leadership and participants are outlined. This is a collaborative effort between the core Decentraland team and various District leaders.

    Land Manager

    We started testing a small application that will allow users to choose land parcels and open them in the editor to work on them and also upload their content to the web client. Codenamed “loader”, this dApp allows you to claim test land in Ropsten and launch the Editor to work on your land.

  • Decentraland Project Updates —  Bounties, Introducing Crypto-Collectibles, Partnering With Bancor & Many More

    News and updates from the Decentraland project

    The past few weeks have been filled with several exciting milestones. We completed our highly-anticipated Terraform Event, announced multiple partnerships, and outlined how crypto-collectibles can be integrated into Decentraland. Here are the highlights:

    Genesis City Auction Successfully Completed

    Decentraland’s Genesis City consists of 90,000 land parcels, with approximately 36,041 parcels staked to community districts. On December 15th, we launched the Terraform event, or land auction, to distribute the remaining parcels to our community. We quickly saw impressive levels of participation, with bids on some parcels reaching 600,000 MANA. Winning bids totaled 161,483,050 MANA, all of which has just been burned (as shown here). At the time of writing, this represents about 16% of the circulating MANA supply, and a total spend of over $28M USD, making this the largest ever virtual land sale.

    The creation of the first blockchain-based metaverse is now underway. Users are already building experiences like Decentraland University , crypto-exchanges, Vegas City, Crypto Valley, the Fashion District, and much more.

    Just as importantly, we're currently working on returning all unspent MANA to users wallets. This will be taking place throughout the rest of the day. Also, all lands will be distributed to their corresponding owners over the weekend. Finally, if you are a district leader, we will get in touch with you next week to help you arrange the multisig wallet that controls your district's land.

    Over the next couple of weeks, we will be releasing the first version of the LAND wallet, which will enable you to visualize your holdings. By the end of Q1, this wallet will be a fully-fledged decentralized exchange for the LAND.

    MANA Token Information

    To help our community better understand the MANA token, we are launching a transparency dashboard. This includes a summary of the most important stats, such as total supply, circulating supply, and how these may be affected by the aforementioned (and all future) MANA burn, as well as by vesting contracts.

    See: Decentraland MANA Token Information

    Major Crypto-Exchanges Join the Terraform Event

    Existing businesses have flocked to Decentraland with the goal of developing realistic, immersive experiences for their growing communities.

    We were excited to see many of the largest cryptocurrency exchanges participate in the Terraform Event, including OKEx, Huobi, BigONE, Exchange Union, and HitBTC.

    The value that Decentraland can bring to these platforms was readily apparent to their management teams. By participating, these exchanges are securing a place within Decentraland to build a virtual environment for their millions of users.

    MANA Bounties for 3D Designers on Ethlance

    To promote development within Decentraland, we partnered with Ethlance to connect landowners with a community of freelance 3D modelers and designers.

    All you need to do is head over to the Find Candidates page on Ethlance and select “Decentraland Scene Developer” in the skills bar. From there, you will be able to access a list of 3D experts to help you create your virtual dream project.

    To promote participation, we offered a 1,000 MANA reward to the first 20 qualified designers who signed up. We were pleased to see 3D experts sign-up from all over the world, including the United Kingdom, the United States, and Singapore.

    Introducing Crypto-Collectibles

    Crypto-collectibles are cryptographically unique, non-fungible digital assets. Unlike cryptocurrencies, which require all tokens to be identical, each crypto-collectible token is unique or limited in quantity.

    The most famous example is the CryptoKitty. Within a few weeks, CryptoKitties hit over $12 million in sales, accounting for 14% of Ethereum’s transaction volumes.

    Decentraland is positioned to benefit from the explosion of crypto-collectibles as it offers an immersive space to explore, purchase, and showcase unique digital assets. To this end, we partnered up with DDEX to foster the development of a decentralized exchange of collectible items.

    Partnering With Bancor to Increase MANA Liquidity

    On December 14th, we announced a partnership with Bancor to create a joint MANA/BNT Token Relay — a decentralized liquidity pool of MANA and BNT, enclosed in a Bancor-compliant “Smart Token”.

    This Token Relay (which is already active) has two connector balances, one in MANA and one in BNT, each at a 50% weight, enabling users to quickly transform ETH or BNT (or any other token on the Bancor Network) into MANA through a widget that will reside on our core products.

    This partnership marks a huge step forward in opening Decentraland to the world. The implementation of Bancor’s Token Relay will dramatically lower barriers to entry as you no longer need an external exchange to acquire MANA.

    Read More: Decentraland & Bancor Partner to Create MANA/BNT Token Relay

    Building Crypto Valley — A virtual hub for the blockchain industry

    On December 18th, we closed a deal with Aelf and FBG Capital to build a digital space within Decentraland called Crypto Valley. By building Crypto Valley (a virtual Silicon Valley), Decentraland is positioned to attract the interest of additional blockchain projects and investors.

    In this digital city, projects can form collaborative workspaces, hold meetings, announce breakthroughs directly to their communities, connect with a global investor base, and interact with potential partners. This could change the way blockchain projects are created, funded, and managed.

    Partnering With RCN to Bring Credit Loans to Virtual Businesses

    We’re preparing for an economic boom within Decentraland. To meet the needs of our growing virtual economy, we partnered with RCN to provide capital to Decentraland endeavors.

    RCN is a global peer-to-peer credit network based on cosigned smart contracts which are backed by Ripio. This strategic partnership establishes a disruptive channel between virtual reality and global credit services.

    Partnering With Render Token to Provide Real-Time 3D Graphics

    Our partnership with OTOY’s Render Token (RNDR) will power the ever-evolving landscape of Decentraland.

    Decentraland’s virtual ecosystem is a perfect match for the distributed network of GPUs provided by RNDR, and will further our mission of decentralizing the infrastructure that powers our virtual world. We’ll be releasing more updates as this project develops and takes shape.

  • Developer Tutorial: Object Transitions and Rotations

    Learn how to use transition and rotation settings when moving entities around your scenes

    In this quick overview, we’ll look at transition and rotation settings in the Decentraland SDK and how they can be used with the entities of your scenes.

    It’s important to remember that in Decentraland, you specify the exact location of an entity using x, y, and z coordinates. The Decentraland engine then renders the entity at that location. If you want to move an entity from one position to another, you simply change the x, y, and z coordinates. The engine then re-renders the entity at the new position.

    So, for example, if a box is in one corner of your scene and you change its coordinates to the center of the scene, then the engine figures out which “path” the entity needs to follow in order to move to the new position.

    The same applies to rotations, in that you set the angle an entity is facing. If you ever change that angle, then the engine will rotate the entity to face the new direction.

    Transitions determine the rate at which changes in a scene appear to a player. These transitions are often referred to by game developers as “lerping”. Even though the state change that describes the new position may be instantaneous, transitions make the changes appear smoothly.

    Imagine moving a box from point A to point B. You don’t necessarily want your box to magically teleport to point B. Instead, you want it to slide across your scene from point A to point B.

    Let’s take a look at where transition and rotation settings are applied to entities and how different timing selections impact the appearance of transitions.

    Throughout this tutorial, we’ll use the same basic scene to showcase different ways in which transitions can be used. Since transitions are only manifested when something changes over time, we’re going to use a simple PointerUpand PointerDown event listener to trigger changes in the scene.

    import * as DCL from ‘metaverse-api’
    import { createElement, ScriptableScene } from “decentraland-api”
    export default class Movement extends ScriptableScene {
      state = {
        buttonState: 2
      async sceneDidMount() {
        this.subscribeTo(“pointerDown”, e => {
          this.setState({ buttonState: 2 })
        this.subscribeTo(“pointerUp”, e => {
          this.setState({ buttonState: 3 })
      async render() {
        return (
              position={{ x: this.state.buttonState, y: 1, z: 3 }}
              transition={{Add your transition here.}}

    For reference, we’ll use the Entity Interface section in the documentation.

    Let’s start off by looking at what happens when there is no transition applied to a position change:

    When we click, or release our click, on the cone to trigger the change in position, it happens instantly. This is exactly what we should expect! While the transition is jumpy, it still changes position.

    Now, let’s look at what happens when we add a linear transition to our cone object.

        position: {
            duration: 200,
            timing: “linear”

    Since we added a linear transition, the movement between the two states happens more smoothly. Furthermore, the acceleration of the object is constant throughout the 200ms runtime.

    Let’s look at the transition when we change the timing to quadratic-in.

    Using different timings affects how your transition appears. Here, the quadratic-intiming adds some punchiness to our transition. The acceleration of the cone has a quadratic progression.

    You can see all of the transition timings listed on the Base Entity portion of the Entity Interface page on our documentation. If you’re using a source code editor like Visual Studio Code, the editor also shows you the list of possible values as an autosuggestion. Just place the cursor where you’d add the timingvalue and type ctrl + space to reveal the list.

    Let’s see how we can use transitions for rotation.

    Here’s our updated code:

    import * as DCL from ‘metaverse-api’
    import { createElement, ScriptableScene } from “decentraland-api”
    export default class Movement extends ScriptableScene {
     state = {
        buttonState: 30
      async sceneDidMount() {
        this.subscribeTo(“pointerDown”, e => {
          this.setState({ buttonState: 30 })
        this.subscribeTo(“pointerUp”, e => {
          this.setState({ buttonState: 90 })
      async render() {
        return (
              rotation={{ x: 90, y:this.state.buttonState, z:0 }}
              position={{ x: 2, y: 1, z: 3 }}
              transition={{ rotation: { delay:400, duration: 200,
              timing: “bounce” } }}

    Let’s see what happens to our cone now.
