Decentralized applications (DApps: Decentralized Application) is one of the new ideas emerging in the blockchain community. With self-executing smart contracts, proponents of the technology have come up with various solutions to try to replace today’s systems that require centralized authority: from businesses to services to governments.
What can you do with dapps? Here are seven interesting projects developed using the Ethereum blockchain.
1.Venue: Make the world more colorful
http://www.govevue.com/
The Vevue project promises to bring Google Street View into everyday life by allowing users to share 30-second video clips of restaurants, hotels, places, activities and more with others around the world.
Users simply need a smartphone to receive Bitcoin or Vevue tokens in a specific area by responding to requests from nearby.
In addition, the project provides a Chrome browser plug-in that allows J to access POI such as restaurants in the Vevue project when searching for local businesses using Google Maps in the browser.
Venue, the “Make videos, earn Bitcoins” app, is already available in the Google Play Store.
Etheria: Building virtual worlds
http://etheria.world/
Etheria is a minecraft-like virtual world that allows players to build creatively with their own map blocks.
According to the project’s website, “This is how the world should be: all player actions should be implemented through a distributed, untrusted environment based on the Ethereum blockchain”.
It points out that until now, all virtual worlds have been controlled by a physical body, but all aspects of Etheria were negotiated and agreed upon by participants in the Ethereum network, without the need for a centralized authority.
This means Etheria will not be reviewed or canceled by the government, project owners, or even the development team. In fact, ethereum will exist as long as it can.
3.KYC chain: Identity management
In the digital age, the increasing risk of financial crime arising from fraud and identity theft also underscores the importance of reliable means to protect one’s identity.
To that end, KYC-chain aims to reach a consensus on individual identity.
The service is currently under construction and uses the existing KYC (Know Your)
Customer), and plans to make the enterprise’s identification process for new users easier to use.
The platform’s “identity wallet” will allow users to share only necessary information.
Based on the Ethereum platform, KYC-chain mainly employs “trusted guards” — they can be any individual or legal entity permitted by law to verify KYC documents — such as notary public, diplomats, lawyers, governments and so on.
The trusted warden uses the KYC-chain platform to individually check and validate the user’S ID. These files will be stored in a distributed database system and can be retrieved by trusted guards or users to ensure proof that the ID is real.
4.4g Fund – Help small business development
http://www.4g-capital.com/
4G Capital provides instant credit for the growth of small businesses in Africa and has developed the concept of using smart contracts.
Investors can use the digital currency to fund small businesses in Kenya. The money lent will be converted and paid to companies using the 4G fund trading system.
Its vision is to provide better financial inclusion and empower individuals, businesses and markets by supporting Africa’s grassroots.
In addition to providing 100% unsecured debt financing to self-employed informal market traders, the project also provides microcounselling and business training to improve client skills and business knowledge.
5. Eth-tweet
https://github.com/yep/eth-tweet
Currently, the project is a working prototype. [Eth-Tweet] is a distributed microblogging service that runs on the Ethereum blockchain. It provides basic Twitter-like functionality for tweets of up to 160 characters.
Distributed means that there is no centralized entity controlling the content published by the participant, and once published, the message can only be deleted by the publisher.
In addition, accounts can receive donations in Ether, and the team suggests that content could be incentivized through the platform.
An Ampliative Art
http://www.ampliativeart.org/en/welcome
Ampliative Art aims to improve the conditions and prospects of artists through a social networking platform.
When completed, the project will become a mutually beneficial online platform through which individuals can contribute to the arts community and receive awards through “alternative means”.
Artists will be able to create their own galleries and exhibit their work for free, and users and artists can be rewarded with tips and donations, comments and reviews, and sharing or exchanging suggestions. The more users contribute to the community, the more likely the community is to reward them.
Any revenue earned by the group will be distributed based on users’ “reputation,” the site says.
As a Dapp, Ampliative Art will be a transparent partner where users can earn rewards and participate in the decision-making process through cooperation.
7. WeiFund: the raise
http://weifund.io/
WeiFund uses Web 3.0 technology to provide crowdfunding solutions for the Ethereum ecosystem.
The project aims to provide a world-class, open source modular, scalable crowdfunding utility that everyone can access. All key builds of the platform are completely decentralized.
To use WeiFund, users need to open the WeiFund in a Web 3.0-enabled browser, such as Ethereum’s Mist. You can then start, contribute, browse and manage crowdfunding campaigns.
WeiFund’s interface and user experience are very similar to those of traditional crowdfunding platforms Kickstarter or GoFundMe, but all funds raised at WeiFund will be calculated in Ether digital currency.
Unlike traditional crowdfunding services such as Kickstarter, WeiFund uses smart contracts, which means donations can actually turn into complex agreements. This gives entrepreneurs a “wider range of possibilities” to raise money, the programme says.
In addition, Web 3.0-enabled browsers will ship with their own wallet system so that WeiFund can make payments to start and participate in campaigns in a “secure and verifiable manner.”
