sandbox is a a virtual world where players can build, own and earn gaming experiences in the Atrium blockchain.

The Sandbox is best known for its two smash mobile hits The Sandbox (2011) and The Sandbox Evolution (2016), which combined generated 40 million downloads across iOS and Android.

how sandbox come in blockchain ecosystem ?

sandbox create in May 15, 2012 and In 2018, developer/Publisher Pixowl decided to bring this successful User Generated Content gaming IP and large community of creators from mobile to the blockchain ecosystem. The goal: disrupt existing game makers like Minecraft and Roblox by providing creators with true ownership of their creations as non-fungible tokens (NFTs) and reward them for their participation in the ecosystem.

The Sandbox blockchain gaming platform consists of three integrated products that together provide a comprehensive experience for user-generated content (UGC) production. The combined products further benefit users by allowing them to secure copyright ownership for their user-created content through blockchain and smart contracts.

VoxEdit

VoxEdit is a simple to use yet powerful free 3D voxel modeling and NFT creation package for PC/Mac that allows users to create and animate 3D objects such as humans, animals, vehicles, foliage, tools and items.
The leading software that allows you to create, rig, and animate your own voxel-based NFTs.
Voxels, which are square 3D pixels similar to building blocks, can be manipulated using VoxEdit to quickly create beautiful creations. Once built, objects can be exported from VoxEdit into The Sandbox marketplace to become NFT game ASSETS.

marketplace

The Sandbox’s NFT marketplace allows users to upload, publish, and sell their NFT creations made with VoxEdit. Creations are first uploaded into an IPFS network to provide decentralized storage and then registered onto the blockchain to prove ownership. Once this is accomplished, creations become ASSETS that can be sold by making an initial sale offer on the marketplace where potential buyers can then purchase them.

Game Maker

The Sandbox Game Maker allows anyone to build 3D games for free. No coding is required thanks to accessible visual scripting tools to create stunning 3D games in minutes. Creators like you contribute to a vast metaverse, filled with a wide range of amazing interactive creations and experiences.

A Game Platform Based On The Blockchain

The Sandbox uses several token types to ensure a circular economy between all the types of users who will interact with the platform: players, creators, curators, and land owners:

• SAND: the ERC-20 token used within The Sandbox as the basis for all of the ecosystem’s transactions and interactions.
• LAND: a digital piece of real estate in The Sandbox metaverse. Players buy LAND in order to populate it with games, assets and interactive experiences. Each LAND is a unique (non-fungible) token lying on the public Ethereum blockchain (ERC-721).
• ASSET: a token created by players who build/assemble user generated content (UGC). ASSETS utilize the ERC-1155 standard and can be traded on the marketplace, with their main utility being to serve as creation elements in The Sandbox Game Maker.

What is LAND?

A LAND is a digital piece of real estate in The Sandbox metaverse that players buy to build interactive experiences. Once you own a LAND, you are able to populate it with Games and Assets. Each LAND is a unique (non-fungible) token lying on the public Ethereum blockchain (ERC-721).

A capped total of 166,464 LANDS will exist within The Sandbox, each contained in a map that forms The Sandbox metaverse.

Two different parcel types are available on The Sandbox map:

• LAND: The basic Sandbox unit on the map. Each LAND comprises 96 x 96 meters in the game world — just big enough to enable all types of blockchain game experiences, but not too large to be unmanageable by a single person.
• ESTATE: An ESTATE is the combination of multiple LANDS. Here is where the potential for teams of creators lies to create larger and more immersive online experiences.

LAND is the epicenter of The Sandbox metaverse. They will allow you to play and create games, earn tokens, host contests and much more!

LAND Presales

If you want to own a piece of The Sandbox metaverse, you can join one of our LAND sales on our map, where LANDs are available for a short period of time.

What is SAND?

SAND is an essential part of The Sandbox platform and was launched on the Binance trading platform in August, 2020. We are working on establishing key mechanics that makes SAND intrinsically tied to The Sandbox platform and its value. SAND is an ERC-20 utility token built on the Ethereum blockchain that will soon serve as the basis for transactions within The Sandbox, and has the following uses.

• Access The Sandbox platform: Players spend SAND in order to play games, buy equipment, or customize their Avatar character. Creators spend SAND to acquire ASSETS, LANDS, and through staking. LAND Sales will drive demand for SAND to purchase LANDS. Artists will spend SAND to upload ASSETS to the Marketplace and buy Gems for defining Rarity and Scarcity.

• Governance: SAND is a governance token that allows holders to participate in Governance decisions on the platform, using a DAO (Decentralized Autonomous Organization) structure. They can exercise voting rights on key elements such as Foundation grant attributions to content and game creators and feature prioritization on the platform roadmap. SAND owners can vote themselves or delegate voting rights to other players of their choice.

• Staking: SAND allows for staking, which provides passive revenues on LANDS: you receive more SAND by staking it. This is also the only way to get valuable Gems and Catalysts, which are required for ASSET creation.

• Fee Capture model = 5% of all transaction volume carried out in SAND tokens (Transaction Fees) will be charged, with 50% of the revenues going toward the Staking Pool as rewards for token holders who stake SAND tokens, and 50% to the ‘“Foundation.’’

• Foundation: The role of the Foundation is to support the ecosystem of The Sandbox, offering grants to incentivize high quality interactive content & game production on the platform. To date, the Foundation is funding more than 15 game projects and granted 100+ artists to produce NFTs ahead of the public launch. The overall valuation of the metaverse will grow through the valuation of all games funded by the Foundation, creating a virtuous circle to enable funding even bigger games and experiences.

How Do Creators Generate Revenue?

• Create Voxel ASSETS

Build ASSETS on Voxedit, import and sell them on the Marketplace as NFTs.

• Build Games with the Game Maker

Build and monetize games and interactive experiences with the Game Maker using your LANDS.

• Own a LAND

Buy a LAND during one of our LAND Sales. Rent them or populate them with content to increase their value!

What is the Game Makers Fund?

The $2M Dollar Game Maker Fund was established in October 2019 to help fund selected creators with the ability to build, share and monetize amazing games on The Sandbox gaming platform. This Fund is supervised by the Foundation’s DAO, whose role is to support the ecosystem of The Sandbox, managing the grant offerings to encourage high quality content and game production for The Sandbox. More than 15 game projects are already in production, supported by the Foundation, including ATARI and Square Enix license-based games that will launch in 2021.

The overall valuation of the metaverse will grow through the valuation of all games funded by the Foundation, creating a virtuous circle that enables for the funding of even larger games and experiences.

The main benefits of being a Creator supported by the Game Makers Fund are:

• Free prime exposure for your games in The Sandbox, one of the most anticipated online PC games of 2020, and the #1 most anticipated blockchain game!
• Maintain full ownership and copyright for your games
• Create your own games using thousands of available voxel assets and visual scripting
• Receive free LAND parcels within the biggest online voxel Metaverse
• Reach and influence an ever-growing community of creators and players
• Monetize your content with our cryptocurrency SAND
• Trade your games and assets on our marketplace
• Be part of our Game Maker community and help define the future of online gaming

Gems & Catalysts

Gems & Catalysts are tokens that will define the tier and scarcity of ASSETS (aka VoxEdit creations imported as NFTs in our Marketplace).

Catalysts

Catalysts are ERC-20 tokens that define your ASSET’s tier and scarcity displayed in the Marketplace. Catalysts add empty sockets to your NFTs that can be filled with Gems; the higher quality the Catalyst, the more sockets available for your ASSET. In other words, the higher the tier, the lower the scarcity, and the more powerful and valuable the ASSET!

50 Partnerships and Counting

The Sandbox team has secured 50+ partnerships to develop content on the platform, including brands like Shaun the Sheep, dApp game studios like Dapper Labs (CryptoKitties), investors such as Square Enix (Final Fantasy, Tomb Raider), and iconic game companies like ATARI (Rollercoaster Tycoon, Pong).These partners secured their own virtual real estate in The Sandbox metaverse and will be among the first to offer multiplayer social experiences upon the public launch of the platform and afterward.

The partnership with Atari involves building games based on their popular IPs such as Rollercoaster Tycoon, PONG, and many other licenses. These projects launched in 2021
