Decentraland is a virtual reality platform published on Ethereum and MANA is a circulating token in the ecosystem. Build on Ethereum while helping others establish state channels. By pledging tokens, users can acquire a certain amount of land in the game, which can be sold for a markup after development. Decentraland consists of a decentralised network consisting of individual estates in which users have full control. Land is purchased through MANA, and users can build various scenarios or mini-games on their plots, and plots can be organized into communities to create shared Spaces of common interest and purpose.

It aims to solve the problem of platform makers earning intermediate platform profits for decentralized open source projects, thus achieving a low price payment model between content creators and game players; The project uses blockchain technology to acquire and transfer virtual property rights, and allows users to hold these virtual property rights permanently and even operate them to make profits for their own content creation.

MANA is a chain game, which is not well known in China at present, but is quite popular abroad. The project started to build a team to develop the project in 2015, and it took two years to prepare before it was officially launched and issued coins. The current application scenarios have been landed, and the game experience is good. The project has made good progress in one year. The model of the project is based on the virtual reality application. The creator releases high-quality content to attract traffic and increase the value of the plot. The plot needs MANA tokens to purchase, thus forming a commercial value, which is conducive to the increase of the currency price. Not only can you create value by launching your own app, but you can also allow players to make payments directly from the virtual platform.

Decentraland has limited contiguous area on the block. Contents on adjacent plots can be seen from a distance. For content creators, establishing regions can provide the ability to achieve targeted traffic; This makes it easier for the end user to explore the subject area. The adjacent principle is the opposite of infinite land: in this case, it is not easy for the user to walk across the land to find relevant content. However, if land is limited, developers can acquire users by buying high-traffic areas. As a result, a secondary market will develop for buying, selling and leasing land.

1) Consensus layer: Tracking territory ownership and content Decentraland maintains a block ownership ledger in the virtual world using A Decentralsmart contract. 1) Decentraland has a daily cap on how many transactions can occur. 1) Consensus layer: Tracking territory ownership and content Decentraland maintains a block ownership ledger in the virtual world using decentralsmart contracts. We call these irreplaceable digital assets "territories" : each territory has a unique (X, Y) coordinate, a domain owner, and a reference to a content description file that can be used to encode what the domain owner wants to provide. Decentraland users connect to the Ethereum network to receive status updates on their territory smart contracts. Territories need to be purchased with MANA tokens. This is a replaceable ERC20 token with a fixed supply. MANA tokens are substitutes for the cost of claiming territory. The territory contract has a destruction function, which creates a new entry in the territory register by destroying MANA tokens. New Territories must rely heavily on already claimed territories. Decentraland uses a decentralised storage system to distribute the content required to represent the virtual world. 1. Every transaction sent has a cap on how many transactions can occur. Each piece of land to be presented will have a reference to a description file for the contents of that piece of land, which can be retrieved by smart contract. It offers a better solution. This decentralized distributed system allows Decentraland to work without any centralized server infrastructure. Thus, as long as users distribute content and transfer the cost of running the system to other participants who can benefit from it, the virtual world will last. Furthermore, this system can provide strong censorship resistance to Decentraland, eliminating the power of centralized authorities to force rule changes or prevent user participation. (3) Real-time layer: : Visitors in the user world can communicate with each other. Users can communicate with each other through P2P connections through domain owners or third-party hosted servers. Without the need for a centralized server,P2P connections can provide social interaction between users and applications that territory-owners want to run on their land. In order to coordinate the bootloader for P2P connections, domain owners must provide staging ground servers, otherwise users cannot see each other in their plots. Such servers can be maintained with the same incentives as content servers. When a lightweight protocol like STUN12 can cover the functionality required by the server, the cost becomes considerably lower. But more advanced features, such as voice communication between multiple concurrent users or network traversal services, can be paid for through micropayments.

MANA will now be used as a proxy to measure New Territories. Domain ownership can only be obtained with the ERC20 token MANA. MANA can bring value into the Decentraland network and purchase New Territories. MANA can also be used to purchase goods and services in the world Decentraland. It can also be used as an incentive to encourage content creation and user adoption. MANA is used to purchase goods and services, creating practical value for tokens. All unclaimed territories can be purchased at the same exchange rate (1000 MANA = 1 territory).

1.Decentraland is a decentralised system that is a virtual space hidden in the world of the Internet, rather than a server run by a company. 1.Decentraland is a decentralised system. You don't need anyone's permission to use this space, as long as you run the program and connect to the Internet, you can use it. 2. Decentraland has a decentralised structure that makes it more stable and vulnerable. 3. Using blockchain to record user ownership, through an identity system, users will be able to track and verify whether a piece of content has the consent of the originator through cryptographic signatures. 4. This is the world's first base block chain platform for the virtual world, an innovation in the field of virtual reality VR you can have your own virtual space, and you can control your own virtual space, their application to create value, as in the virtual space platform game of their intellectual property rights. 5. The project has good feasibility and a promising future. The closed loop of the product has been completed. In the game, land is scarce, purchasing land requires MANA, and once it is auctioned off, it can be created with the SDK tools, and the player can complete any fantasy he or she desires.

1. The incentive system of the game is well combined with the Token equity mechanism. Instead of simply tokenising game points, Decentraland designs two digital assets within the system: land and MANA coins. MANA is ERC 20 coins, and land is priced and traded in MANA. Both digital assets can be traded on the secondary market, solving the problem of digital asset circulation caused by the closed system of traditional games. This design is key to differentiating Decentraland from other games: similar to real world real estate markets, there is a centre and edge difference in land prices for a limited amount of land. 2. The wider possibilities of VR technology expand the application scenarios of the project. Decentraland may look like a blockchain version of Minecraft, but VR technology opens up many more possibilities. Many brands using VR marketing can also generate more exposure on Decentraland or earn revenue directly.

Decentraland provides infrastructure support for a shared virtual world. The land on Decentraland is closely connected, which makes it distinct from a domain. The new plot must be adjacent to the existing plot. This feature facilitates the discovery of space for new content, as well as reserving space for specific themes or regions. Decentraland's scripting language supports developing applications, games, bets and dynamic 3D scenes. The scripting language has many capabilities, including creating objects, loading textures, handling physics, and encoding user interactions, sounds, payments, and external calls. Creators can build scenes on the upper layer of their own land and sell their designed virtual products and services to earn MANA. Because blockchain-based technology can uniquely identify their works, the intellectual property rights of creators or service providers are guaranteed.

Decentraland's most similar competitor is Mark.Space. It's also a blockchain-based VR marketing scene, but Mark.Space is more commercial, less game-based, and a bit later. CEEK is also based on blockchain technology, but it only uses Ethereum's smart contracts for ERC 20 tokens. Other VR + blockchain projects are at similarly early levels.

Decentraland's core team members have a lot of blockchain experience and development capability. However, as per the roadmap, Decentraland has already been put on hold and will eventually move to the electronic age. On the bottom, Decentraland is technically dependent on Ethereum and IPFS, so its future development is limited by technology. The project has high technical requirements, but no technical reserves, and there are uncertainties in technology implementation. Of course, the combination of VR and blockchain brings some possibilities to this project and has great market potential.

Limited by the number of data transmission degrees of P2P networks, data security risks exist. 1. Download speed. Getting files from DHT or distributed point-to-point storage systems has historically been very slow. Especially in graphical applications such as Decentraland, it is detrimental for the user not to be able to load quickly. Second is the availability of content: whether content can be distributed enough on the network without being lost can make the difference between life and death. 2. The project still has many problems that have not been solved so far. When will VR reach the mass market? Will MANA become a widely used medium of exchange for DCL, or will all value be added to land? Does the actual user experience deviate from the expected value? Does the number of players directly affect the economic value of the land? Is the data model up to date over time?

MANA acts as a circulation medium in The City, and its value is directly proportional to the flux of land, props and services in the city. As long as the number of users, developers and scenes in the city increases, the value of MANA will have certain psychological support. The real value of land should be directly proportional to the game revenue generated in Genesis City, which is not closely related to MANA. Due to the uncertain future of Decentraland and speculation games, land investment may not be suitable for ordinary players. At present, investing in MANA is much less risky than investing in land. Two points can be used as an important index for reference, is gray funds have to participate in, the current coin case, variety, but gray participation are just the few of the, so are evident value, another is 10, according to the current address they are overweight, not blindly go to sell, this is a good phenomenon. MANA has some value in the long run, at least above its previous high.

MANA project was born very early and started in 2017, so it must have been brilliant, but now it has been surpassed by many similar projects. At present, the circulation rate of MANA tokens is 72%, and the number of coin holding addresses is just over 100,000, all of which are neutral, so it is not clear whether there is investment value. Can also be judged according to gray fund participation and ten circulation address

Decentraland's value proposition for application developers is that they can capture the full benefits of the economic interaction between their applications and their users. In order to facilitate the trade of virtual goods, there must be financial incentives to ensure that avatars, items, and scripts are generated and released. Since static content can be copied at will, the user experience should reinforce the social consensus that recognizes the originality of content. With an id system, users will be able to track and verify that a piece of content has the consent of the originator through an encrypted signature.
