  • What is 3DCoin?

    3DCoin is a peer to peer blockchain based platform allowing users to manage their business automatically by programming transactions to fulfil any contract. In other words, it cuts out any third party or a trusted escrow, which is an impressive change.

    smart script

    system is based on the Bitcoin stack system, improvements were brought to functions making them take arguments thus exploit all the depth of the stack and simplifying the scripting process.

    masternode requirements

    Masternode require to have 1000 3DCoin collateral, a dedicated IP address, and be able to run 24 hours a day without a more than a 1 hr connection loss.

    block reward

    The block reward is 16 3DCoin and divided 25% miner and 75% Masternode

    3DCoin Vision

    Project Districts stemmed from a passion to create a boundless environment where real-world limitations and shortcomings are rendered invalid – In this world ‘possibility is the watchword. We wanted a system that nullified traditional barriers to innovation, one that went on to replace such limitations with the necessary tools needed to innovate, create and condensate ideas into workable solutions.

    To create this world, the Districts development team recruited the services of two innovative technologies, the blockchain, and Virtual Reality - each disruptive in its own right. Project Districts leverages the core efficiencies of these two pioneers of 21st-century innovation, to create an immersive virtual ecosystem, complete with virtualized real-life entities existing in a real-time interactive environment. This synergistic manipulation of the Blockchain and Virtual reality is an industry first, more importantly, however, it is one that allows us to integrate a diverse range of functionalities into the Districts 3D world.

    Ultimately, Project Districts will be a thoroughly robust ecosystem where productivity, recreation, and innovation come to roost, much similar to the real world, only this time without its associated complexities. Our goal is to be the worldʼs first ubiquitous interface for propagating traditional and ethereal experiences to both the everyday internet user and the tech-savvy geek.

    Details About Project Districts

    High-End Applications

    Districts Visual Studio has native support for the development of a broad range of applications, which will be commissioned into the Districts ecosystem as a DAPP. A user-defined DAPP could be anything – it can be as basic as a virtual key or as complex as full-scale MMORPG – It all boils down to the needs and creative tendencies of the user. If your goal is to build another Districts ecosystem inside of the original Districts 3D world, fret not, Districts is built to support the most demanding and resource consuming DAPPS. Bolstered by the robust decentralized framework of the Blockchain and sailing the winds of our technical partners inclusive of steam VR, Oculus, Allegorithmic, Unreal Engine to mention but a few, Districts combines all the necessary technologies to provide a cocktail of digital excellence.

    Provision of Real World Utilities

    Districts 3D world provides a solid basis for the establishment of enterprises that provide virtual value-added services that can be availed in real life. Business owners and entrepreneurs can set-up custom entities such as shopping malls, online virtual classrooms and even virtualized health facilities – as was with application development the extent of the business idea is only limited by the developing entity. And unlike conventional methods of starting up and running a business, the Districts business model scales through traditional limitations of exorbitant expenses, bureaucracy, and cumbersome regulations.

    Advertisement and Content Promotion

    Districts immersive world provides a fertile ground for all forms of targeted advertising. Say a marketer is looking to advertise his gaming title, he/she can simply hoist up a virtual banner in any of Districtʼs virtual gaming environment. Similarly, billboards, posters, and fliers can be displayed at strategic positions in the 3D world; brands can also create virtual experiences geared towards advertising and marketing their products.

    Networking and Social Interaction

    Districts would also be a place to meet new people. Users will be able to interact in real-time in the 3D world via custom-created avatars or through chats on the networkʼs forums and groups. Virtual concerts, shows, broadcasts, and parades can also be hosted in the 3D world

    The Districts Ecosystem

    The focal point of the District ecosystem is its users. Straight from launch Districts will come with a predefined 3D world template complete with fundamental entities and architecture. It is atop this predefined model that users would be able to create their own custom entities using Districts visual studio (DVS). User-defined objects are commissioned into the districts ecosystem as flexible, decentralized applications or DAPPS Districtʼs 3D world is a miniverse of its own. What this means is that real life entities like other humans (users), business buildings, hospitals, schools, cinemas, etc. will exist as standalone entities with full interactive capabilities. So, unlike traditional VR and AR technologies that allow for localized visualization and in some rare instances, interaction; the Districts 3D world allows for visualization, interaction, and real-time participation with actual real-life consequences. Say a 3D world user walks into a shopping mall hosted in Districts 3D world and makes a purchase, he/she will receive a valid receipt of purchase and subsequent real-life delivery of such a product. This consequential nature of the Districts 3Dworld is what guarantees its place as the revolutionary virtual reality solution with use cases applicable to everyone. A doctor can treat his/her patient on Districts, so also can a gamer play his favourite games; a businessperson can set up the mall of his dreams with a fraction of the resources itʼd take to do so in real life. Whatever fits the preference of the user.

    Market opportunity

    Three years ago virtual and augmented reality were just ‘workable ideas,ʼ today however on the back of both being revolutionary in impact some might describe them as the cherry topping of the 21st-century innovation drive. A quick performance analysis of the key players (counterpart technologies) like Oculus VR, HTC Vive, and Google cardboard reveals a steady improvement in operational capabilities and fiscal performance in the last two years; this is despite repeated technical setbacks within this same period. Project Districts comes into the VR/AR scene peering from the shoulders of these pioneer technologies. That said, Projects District is uniquely dissimilar from the first generation VR/AR tech. Unlike the latter which focus majorly on hardware development for the experience of a 3D world, Project Districts is that 3D world where all first gen VR/AR tech will demonstrate their use capabilities. This all-encompassing nature of Districts ultimately means that use cases of individual third party VR/AR technologies will be ported to the Districts Ecosystem.

    Aside from this potential integration with existent VR/AR tech Districtʼs own native collection of DAPPs is an investors delight. Since the Districts 3D world recreates all aspects of the real world, users can design virtual instances of real-world entities like malls, hospitals, and schools with real-world consequences. The import from this is that investors can invest in the development of profitable DAPPS that provide value in the Districts ecosystem much like they would in real life. Only this time at a fraction of the cost and without the correspondent risks.

    In a world where the costs and complexities of starting up a profitable entity continue to skyrocket, DAPPs represent the future of scalability and affordability. With regards to profitability, the profit margin of DAPPS when implemented will be significantly higher than traditional methods of undertaking businesses, since they run on a decentralized blockchain that eliminates traditional costs, expenses and barriers to business operations. At the official launch of Districts 3D world and subsequent to global adoption and user base growth, DAPPs will become the engine room of the Districts ecosystem.

    Fuelling this engine and serving as the official medium of transaction in the Districtʼs ecosystem is 3Dcoin – Project Districts own cryptocurrency based on the bitcoin and dash source code. 3Dcoin is scheduled to go live on 02 February 2018 when it will be listed in global cryptocurrency exchanges. Fiscal predictions for 2018 Q1 hint to a more than proportional increase in the value of the cryptocurrency which unlike most other cryptocurrencies, is backed by a real-world entity – Project Districts. As of November 2017, the 3D coin coinbase is worth 200 million 3DC. 75% (150million 3DC) of this sum is dedicated to the ICO, which on completion will serve as an initial funding round for the project. The remaining 25% is split into four portions;

    • 10% for early investors (locked for one year)
    • 10% for the development team (locked for five years)
    • 4% for the Districts board of advisors (locked for one year).
    • 1% for the bounty campaign

    Given the already burgeoning demand for 3Dcoin, and considering its fiat nature in the 3D world, one can only expect the best for the cryptocurrency in the world market come next year.

    Architecture 3DCoin Blockchain

    3DCoin is the driver of the Districts Ecosystem; it is a cryptocurrency developed using Bitcoin and Dash source code with added legacy features for redundancy. The 3D coin blockchain uses a set of public key cryptographic methods that further improve its safety and allows for the use of already existent keys from sister cryptocurrencies or from any other system for that matter. For instance, if a user has a PGP key for his/her email, he/she will also be able to use to receive 3Dcoins.

    The blockchain which is made up of 1 Megabits blocks linked to form a simple chain, stores all forms of relevant data associated with the Districts ecosphere, be it transactions history or building references – with every block referring to the hash of the preceding block. Transactions are saved in the format of a Merkle tree (a sequential order of hashes), and of the 1 Megabits storage space, 30% will be dedicated to encoding details of small feeless transactions. Each block hosts a specified number of data capsules which in turn holds scripting information about Districtʼs Decentralized Applications (DAPPS)

    Decentralised Hosting

    The architecture supporting Districts 3D world and its Decentralized Applications (DAPPs) is hosted atop a decentralized blockchain network. Unlike conventional centralized server-based systems, Districts distributes content essential to its functionality among the users of this P2P network who then shoulder the major resource implications of floating the 3D world. This architecture, aside from making the 3D world thoroughly redundant and practically impermeable to third-party intrusion theoretically gives all powers of governance to the community.

    As an incentive for hosting the 3D world framework participating users will be apportioned both token based assets (land and 3Dcoin) and, in the case where the contribution exceeds a set threshold, the title of Master-Node which comes with its own set of attractive perks.

    Decentralized Network(Master-nodes)

    In very simple terms a master-node is a dedicated server (node) on a decentralized network (in this case the 3DCoin blockchain), that runs a copy of 3DCoin’s blockchain and performs specific functions in real time. Compared to normal nodes, ‘Master’ – nodes are typically more robust, possess advanced capabilities and require sizable resources to run. But that’s just your typical master-node, the 3DCoin master-node is this and more, and amongst other things, it has the capabilities to:

    • 3D World client synchronization(Pulse-node)
    • Host decentralized applications(Pulse-node)
    • Tokens’ Blockchain hosting(Prime-node)
    • Host coin blend sessions(Prime-node)
    • Cast a vote for content control in Districts client(Prime/Pulse-node)
    • Orchestrate instant transaction services(Prime-node)

    As was noted earlier, running a master-node capable of performing these functions can be resource intensive. Which is why the 3DCoin master-node feature comes with a rewards system that offers incentives redeemable as a percentage of every transaction facilitated by a master-node. By hosting a 3Dcoin master-node, users are contributing their quota to the propagation of the 3DCoin blockchain and in so doing setting up a mechanism for earning passive income. It’s a win-win situation for investors and the Project Districts ecosystem.

    You can think of master-nodes as ‘superintendents’ of the 3Dcoin blockchain. Superintendents in the sense that their advanced capabilities allow them to orchestrate and fast-track otherwise tedious and time-consuming transactions (transaction, in this case, encompasses all processes run on the 3dcoin blockchain). More master-nodes translates to a robust, faster and more efficient 3DCoin blockchain. Which in turn fosters smoother operations in the Districts 3D world. Currently, all running master-nodes are involved in the mining of 3DCoin. When the specified maximum supply of circulating 3Dcoin is reached, users can then upgrade their master-nodes to a Districts Prime/Pulse node.

    A Districts Prime or Pulse node is a multichain node tasked with storing all the blockchains created in the 3DCoin blockchain architecture. While conventional nodes (master-nodes inclusive) run a copy of the blockchain, Prime-nodes take it one-step further and store every blockchain created in the Districts ecosystem. Their overseeing role in the architecture of the 3DCoin blockchain sets them up to undertake other advanced functionalities. Pulse-nodes are responsible for Project Districts p2p synchronization. They integrate individual factions (i.e., users) of the 3DCoin blockchain and position them to function in synergy and as a composite whole. Furthermore, they foster instant hosting of decentralized applications (3D Dapps).

    Decentralized Applications

    Decentralized applications are the functional units of the Districts ecosystem. They are the primary value proposition of the Districts 3D world, and it is through them that all segments of the Districts experience will come to life. A DAPP is comprised of two blocks

    • The visual engine, encoded using an Unreal Engine library and part of Districts client side.
    • A script fashioned by Districtʼs visual script encoding platform parsed in a data capsule and hosted atop the blockchain network.

    In practice, this configuration allows the blockchain network to run ‘lightʼ and with minimal bandwidth, since resource intensive properties, like textures, 3D modelling, etc. are served from the client end.

    Ownership of a Decentralized application is defined by a scripted transaction which securely stores the details of the DAPPʼs data capsule. By default DAPPs can be used freely by any user, creators can, however, set specific conditions and requirements that define how a DAPP can be accessed or used. Owners can also modify a DAPPs script (as would be necessary for the event of a transfer of ownership). Modifications will be broadcasted on the Districts blockchain as an updated scripted transaction subject to verification by a network consensus. If a script possesses unrecognized functions the updating attempt will be rejected.

    Districts Visual Studio

    DVS is a modern, comprehensive, and robust IDE, comparable to the Ethereal developer portal presented in a fluid and easy to use interface. This minimalist interface features an easy to use drag and drop creation mode that allows users to select and implement a variety of functions such as texturization, scheduling custom animations or even visual scripting by simply ‘dragging and droppingʼ using a mouse or through VR controllers. Complex model interactions and trigger properties are defined as a tree of processes and conditions in an interactive map which when completed is parsed into the application by the DVS. DVS also come bundled with a diverse and expandable library of functions, textures, sound and 3D modelling templates that make the job of building and commissioning a DAPP all the more easier. Interactive tutorials that walk every user through the DAPP creation process will be found in the starting area of the Districts 3D world. In addition, a dedicated forum section where users can ask questions and contribute answers to other users will also be set up to foster seamless operation of the DVS module. Before final release, content creators can test run their finished DAPPs in offline mode, if the test phase is successful, an encoded script is generated by the DVS and stored in data capsule. Subsequent modifications to the DAPP can be effectuated by compiling add-on scripts which will then be incorporated as updates to the Districts library.

    Content Acquisition and Payments

    Like was noted earlier, ownership of a virtual asset (in the form of a DAPP or land token) and clearance to use such an asset or service is defined by a scripted transaction. When a third party purchases the right to use a DAPP (in the case of curated contents) the ownership function previously defined at the point of creation of the DAPP creates a payment transaction that houses a specific transaction code. DAPPS are by default configured to check for and then authenticate a transaction code before granting the user access.

    Once the decentralized application is completed, a land parcel in the 3D world must be acquired to receive the virtual building that will host it. This land parcel is intrinsically defined as a Land token.

    Land Tokens

    Land Tokens defines what entity owns which land parcels in the Districts 3D world. By default, they are linked to the Decentralized Application which they host, although both can be traded freely. Ownership, as well as the precise geolocation (x, y, z coordinates) of a land, will be set and saved in the same scripted transactions as the DAPP.

    Users have the option of selecting land parcels contained in either the pre-portioned or pre-categorized segments of the Districts 3D world, where land dimension are present or in a District Sandbox where they can freely specify a preferred location and size. The first 25 land tokens representing the first ring of platforms in the 3D world will be ascribed to top investors. Every other parcel will have to be purchased with 3D coins either from the Districts server, in which case the 3D coins will go to the development fund or from other users.

    Transactions on the network

    Transactions on the blockchain network are inalterable specifications from which a balanced consensus is reached between the two involved parties. Contained in their metadata is information describing the amount of transferred asset (e.g., 3D coin), the public key of the sender and that of the receiver. Each transaction is processed with a micro fee paid by the sender and redeemed by miners (see below). Micro fees vary by transaction volume – the larger the transacting size, the greater it's correspondent micro fee. Users also have the option of parsing a smart script that programs transactions to effectuate at set conditions, or that defines the ownership status of land parcels and DAPPs in the Districts 3D world. When a user wants to send funds (in the form of 3D coins), the Districts Wallet Application will broadcast a message containing the incoming transaction (with associated details) to the blockchain network. The network then authenticates this request by confirming the ownership of the said funds and validating the identity of the receiver before embedding the transaction into a block in the Blockchain network. On the other hand, transactions defining just land ownership and DAPPs do not effectuate any transfer of monetary value – their sole purpose is to refer to the data capsule that contains information regarding the DAPP script, its legitimate owner and the parcel (x,y,z) coordinates in the 3D world.


    • A public key that, when hashed, yields destination address D embedded in the script.
    • A signature to show evidence of the private key corresponding to the public key just provided.

    Scripting provides the flexibility to change the parameters of what's needed to spend a transferred asset. For example, the scripting system can mandate the provisioning of two private keys, or a combination of several, or even no keys at all.


    Mining on the Districts blockchain is via a proof of work algorithm – designed to decrease the probability of creating two similar blocks in the same instance. This is achieved by running a set of unique block data through The Keccak hashing algorithm - is one of the five finalists in the NIST hash function competition. When the resulting series of numbers meets certain criteria, the block is considered to be mined. It is then broadcasted to the network and added to the base blockchain after taking the said series of numbers as its hash. (Mining can be carried out using a GPU, CPU, or any other mining hardware)

    Once a block is mined, a block reward consisting of newly generated 3DCoins is distributed among Miners (25%), Node operators (75%). On very rare occasions, more than one block is mined in the same instance, presenting a situation where peers have differing last blocks added to their blockchain. In such cases, the network simply synchronizes to the block that was mined by the majority of the blockchainʼs users.

    Coin Blend

    One shortcoming of disclosing public key on the blockchain network is that it to some extent reveals a portion of the end userʼs identity. To maintain 100% anonymity the Districtʼs blockchain utilizes a cryptic Coin Blending algorithm. Coin Blend starts from the userʼs wallet application where he/she specifies the transaction to be anonymized. The wallet then splits the transaction into standard ‘blendableʼ denominations (10, 1, 0.1 and 0.01) before proceeding to randomly match the transaction to a SuperNode which handles the blending process. From here the transaction is placed in a blending queue, where three matches for the standard denominations are found. The SuperNode then casts a readiness alert to three unique wallet applications, and once they respond with confirmation, the Blending session starts.

    Each of the three wallets sends both the input to be mixed, and a newly generated public key that will receive the anonymized funds, from them, the SuperNode creates a triple transaction containing the three inputs, and the three receiving public keys. The triple transaction is sent to the three wallets, they verify the exactitude of the inputs and the public-keys, sign the transaction, and send it back to the SuperNode. At this point, the SuperNode has a triple transaction with three signatures, after a final verification, this transaction is broadcasted like any other one to be added in a mined block, and finally into the blockchain.

    Sub Currencies

    Users can also create Non-fungible assets using the Districts wallet application. Creation of these assets which can be used as tokens, shares, coupons or any other entity of value is a non-reversible process that splits a single 3D coin into 100 units of the specified sub currency (asset). As an example, a user can decide to create 100 SC representative of a companyʼs stock. These sub currencies can then be distributed among participating shareholders as a placeholder of value (stock).

    Conditional Transactions

    The Districts Framework and the 3D coin blockchain also has native support for conditional transactions, otherwise known as smart contracts. Conditional transactions can only be fulfilled if and when all accompanying conditions specified in the transaction script are met by the transacting parties. A simple visual tool will be available in the wallet application to set such transactions; the resulting broadcasted message contains both the transaction and the conditions script. The main conditional parameters are Time, Public-key, and Password.
