AAAChain is a big data public chain, dedicated to using blockchain technology to create a community-autonomous, safe and credible data open platform composed of massive vertical scene applications. The project has reached a strategic cooperation with Huanxin, a Chinese instant messaging cloud manufacturer, and will gradually activate the Huanxin ecosystem covering 180,000 APPs, 1 billion mobile terminals, and 50 million daily active users. AAAChain's vision is to build the world's largest public chain of big data and make it the next-generation Internet infrastructure.
AAA Token (App Alliance Association Token, referred to as AAA Token) refers to the native encrypted token on AAAChain. It can be used as a fuel for creating smart contracts for data transactions, and can also prevent DDoS attacks; settlement and sharing of data transactions; AAAChain supports DApps on the platform to create and issue their own tokens based on smart contracts for unique purposes within DApps ( For example, in-app payment), and the transfer between DApp's own Token, all use AAA Token as payment fee; used to motivate behaviors encouraged by the platform. For example, rewards for providing high-quality data, rewards for data quality evaluation, etc.

AAAChain Consensus Mechanism

AAAChain adopts the classic DPoS consensus mechanism to determine the mining right of the block. By letting each AAA Token holder vote, the 101 representatives who get the most votes will carry out the transaction package calculation. The rights of these 101 super nodes are completely equal to each other. Each representative takes turns producing blocks according to a predetermined schedule. Compared with Bitcoin's PoW, the advantage of choosing the DPoS scheme is that through different strategies, a small group of nodes is selected from time to time, and this small group of nodes is used to create, verify, sign and supervise each other, which greatly improves It reduces the time and computing power cost required for block creation and confirmation, and the consensus verification time designed by AAAChain is in seconds.

Application scenario

1. Main application scenarios
AAAChain data open platform provides a decentralized, credible, fair, compliant and autonomous data open platform. Customers from various industries can use this platform to conduct transactions, covering the main monetization scenarios of the Internet.

2. Application scenario example - digital marketing scenario

In the context of digital marketing, AAAChain will apply the alliance's massive global vertical scenarios. Based on the massive data integrated by the APP alliance, it will collect, clean, integrate, and mine billions of audience data on the global mobile Internet to build the first Three-party accurate crowd data open platform.
At the same time, the alliance composed of hundreds of thousands of APPs itself has the need for advertising monetization, which can be embedded in the advertising SDK for advertising marketing. Hundreds of thousands of APPs as media owners will attract a large number of advertisers and data analysis service providers to join AAA ecology. At the same time, APP can also purchase advertising traffic within the system to meet its own growth needs. When the project goes online, it is possible to form a complete internal circulation ecology from the data supplier to the data consumer.
3. Application Scenario Example - AI Model Trading Scenario

In the AI ​​model trading scenario, AAAChain will focus on the credible circulation of NLP corpus and industry knowledge required for AI model training, and build various manufacturers with one-party data, AI technology manufacturers and data labelers with general chatbot technology , AI model and knowledge map construction manufacturers and the final manufacturers who use the finished AI model or knowledge map constitute a complete ecosystem.
At the same time, the ownership and profit distribution of the knowledge graph produced by training that plagued the industry has also been well resolved in this scenario.
4. Precise advertising case
Participants: car manufacturer A, advertising company B, data provider C, D
Scenario:
• A luxury car manufacturer A There is a new car on the market, and it needs to be advertised to a group of high-income men aged 30-40 who live in a certain city S.
• Car manufacturer A entrusts advertising company B to place advertisements
• Data providers C and D are customers of the AAAChain data open platform: C has the user's location data, and D has the user's age, gender and income data Labels
• Multi-party data aggregation calculation is required for accurate advertisement delivery
Process:
• Advertising company B pays AAA Token after getting acquainted with the platform, and joins the AAAChain open data platform
• Advertising company B sends The AAAChain Open Data Platform initiates a request to purchase data (smart contract),
• The AAAChain Open Data Platform broadcasts this purchase request to App customers who have such data
• Clients C and D on the AAAChain Open Data Platform reply respectively This request goes to advertising company B, giving the data type, description and price they provide
• Advertising company B confirms the purchase data and pays, and the platform executes the smart contract:
The platform will select a computing node for data aggregation Calculation
Obtain a batch of user ids in the specified city S from App C, and pay the fee to C
Use this batch of ids to obtain a data set of user ids that meet the age, gender, and income conditions from App D, and pay the fee Delete temporary data for D
calculation node and get AAA Token reward
Return the calculation result of the smart contract: the user ID of a 30-40-year-old high-income male in S city
• Advertising company B sends to These users place advertisements
• Advertising company B can evaluate the data provider according to the effect and get AAA Token reward

Application scenarios of AAA Token

AAA Token refers to the native encryption token of the AAAChain main chain. The initial form is the ERC-20 smart contract token issued by the Ethereum public chain. Later, it will be exchanged for the AAAChain native encryption token 1:1 after the AAAChain main chain is launched. certificate.
AAA Token mainly has the following key uses:
1. The fuel for creating data transaction smart contracts, and can also play a role in preventing DDoS attacks;
2. Data transaction settlement and sharing;
3. AAAChain supports DApps on the platform to create and issue their own Tokens based on smart contracts for unique purposes within DApps (such as in-app payment), and transfers between DApps' own Tokens use AAA Tokens for payment procedures Fee;
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 circulation of AAA is 21 billion, and the total amount is fixed and will never be increased.
