AAAChain is a big data public chain, committed to using blockchain technology to create a community-autonomous, secure and trustworthy data open platform composed of massive vertical scenario applications. The project has reached a strategic cooperation with China's instant messaging cloud manufacturer Huanxin, and will gradually activate the Huanxin ecosystem covering 180,000 APPs, 1 billion mobile terminals, and 50 million daily active users in advance. AAAChain’s vision is to build the world’s largest public big data chain and make it the next generation of Internet infrastructure.
AAA token (AAA Token for short) refers to a native encryption token on AAAChain. It can be used to create a smart contract for data transactions, and can also play a role in preventing DDoS attacks; data transaction settlement and sharing; AAAChain supports DApps on the platform to create and issue their own tokens based on smart contracts, which are used for unique purposes within the DApp (such as in-app payment). The transfer between DApp's own tokens uses AAA tokens as payment fees; it is used to incentivize behaviors encouraged by the platform. For example, rewards for providing high-quality data, rewards for data quality evaluation, etc.

AAAChain consensus mechanism

AAAChain uses the classic DPoS consensus mechanism to determine the mining rights of blocks. By allowing each AAA Token holder to vote, 101 representatives with the largest number of votes are obtained for transaction packaging calculations. The rights of these 101 supernodes are completely equal to each other. Each representative takes turns to generate blocks according to the established schedule. Compared with Bitcoin's PoW, the advantage of choosing a DPoS solution is that through different strategies, a small group of nodes is selected from time to time. This small group of nodes creates, verifys, signs and mutual supervision of new blocks, which greatly reduces the time and computing power cost required for block creation and confirmation. The consensus verification time designed by AAAChain is in seconds.

Application Scenarios

1. Main application scenarios
The AAAChain data open platform provides a decentralized, trustworthy, fair, compliant and autonomous data open platform. Customers in various industries can use this platform to conduct transactions, covering the main changes in the Internet scene.

2. Application scenario example - Digital marketing scenario

In the digital marketing scenario, AAAChain will use the alliance to apply a large amount of vertical scenes around the world. Based on the massive data integrated by the APP alliance, it will collect, clean, integrate and mine billions of audience data of the global mobile Internet to build a third-party accurate population data open platform.
At the same time, the alliance composed of hundreds of thousands of APPs itself has the need for advertising monetization and can be embedded in advertising SDKs for advertising marketing. As media owners, hundreds of thousands of APPs will attract a large number of advertisers and data analysis service manufacturers to join the AAA ecosystem. At the same time, APP can also purchase advertising traffic within the system to meet its own growth needs. When the project is launched, it is possible to form a complete internal circulation ecosystem from the data supplier to the data consumer.
3. Application scenario example - AI model trading scenario  

In the AI ​​model trading scenario, AAAChain will build a complete ecological system consisting of various manufacturers with one party of data, AI technology manufacturers, data markers, AI model and knowledge graph construction manufacturers, and final manufacturers using finished AI models or knowledge graphs.
At the same time, the ownership and profit distribution problems of the knowledge graph generated by training that plague the industry are also well solved in this scenario.
4. Accurate advertising case
Participants: Automobile Manufacturer A, Advertising Company B, Data Provider C, D
Scene:
• A luxury car manufacturer A has a new car to be launched, which is to promote high-income men aged 30-40 who live in a group of S in a certain city.
• Automobile manufacturer A commissions advertising company B for advertising
• Data provider C, D is a customer of the AAAChain data open platform: C has user location data, D has user age, gender and income data labels
• Multi-party data aggregation calculation is required to perform accurate advertising delivery
Process:
• Advertising company B gets to know through the platform, pays for AAA Token, and joins the AAAChain data open platform
• Advertising company B initiates a request to purchase data (smart contract) to the AAAChain data open platform,
• AAAChain Data Open Platform broadcasts this purchase request to App customers who have such data
• Customers C and D on the AAAChain Data Open Platform respond to this request to advertising company B respectively, giving the data type, description and price they provide
• Advertising company B confirms purchase data and pays, and the platform executes a smart contract:
The platform will select a computing node to perform data aggregation calculation
Obtain a batch of user IDs in the designated city S from App C and pay the fee to C
Use this batch of ids to obtain user id data sets that meet age, gender, and income conditions from App D and pay the fee to D
The calculation node deletes temporary data and receives AAA Token rewards
Return the calculation result of the smart contract: User ID of a high-income male aged 30-40 in City S
• Advertising company B places advertisements to these users through advertising SDK
• Advertising company B can evaluate the data provider based on the results and receive AAA Token rewards.

AAA Token Application Scenario

AAA Token refers to the AAAChain main chain native encryption token. The initial form was the ERC-20 smart contract token issued by Ethereum public chain. In the later stage, it will be exchanged for the AAAChain native encryption token 1:1 after the AAAChain main chain is launched.
AAA Token has the following key uses: 1. Create a fuel for smart contracts for data transactions, and can also prevent DDoS attacks;
2. Data transaction settlement and sharing;
3. AAAChain supports the DApp on the platform to create and issue its own tokens based on smart contracts, which are used for unique purposes within the DApp (such as in-app payment). The transfer between DApp's own tokens is used to use AAA tokens for payment processing fees;
4. Used to motivate behaviors encouraged by the platform. For example, rewards for providing high-quality data, rewards for data quality evaluation, etc. The total issuance of AAA is 21 billion, and the total issuance will never be issued in total.
