3.1 Design Principle

Describe the design principles：Ease of use + security + efficiency + meeting the needs of digital transformation of real industries + positive incentives among business alliances.

Douglas AMC platform uses a witness mechanism with threshold signature to ensure the validity of transaction verification, a cross-chain atomic transaction model to compensate for the poor liquidity of cross-chain assets, and the introduction of a prophecy machine to break the barrier between chain and reality. The system is based on the assets invested by users in the edge chain and calculates the main chain earnings in real time through the prophecy machine exchange rate. On the blockchain, ordinary users can have the real-time experience of asset cross-chain transfer thanks to the investors' assets on the edge chain.

The design principles are as follows：

A. Ease of use

Traditional cross-chain requires users to operate in multiple times, and minimizes user burden through intelligent management. Meanwhile, by introducing artificial intelligence and secure and trustworthy execution mechanisms, a new generation of secure smart contracts is designed, including four easy-to-use features such as authenticity, openness, tamper-evident and block capacity. The secure smart contract based on these four features enables more flexible and open transactions.

B. Security

Ensures the security of user assets through cryptographic algorithms. Combining the respective advantages and characteristics of blockchain and real industry, the distributed service architecture platform applicable to real industry payments is designed. The platform has：Service definition, service registration, service monitoring, remote communication and information exchange, service invocation, cluster fault tolerance and other functions can provide high concurrent and high carrying capacity services based on large data capacity.

C. Decentralization

Everyone participates and there is no centralized institutional control. Since one of the three main features of blockchain is decentralization, the higher the degree of decentralization, the weaker the disadvantages of data centering. Therefore, Douglas AMC's design principles include the need to achieve a decentralized autonomous system, so that every user with passwords and digital assets can have the best blockchain payment experience.

D. Fit for Empowerment

Douglas AMC will accommodate the technical requirements of different blockchain underlying platforms and allow users holding various types of public chain Coins and ERC20 and BSC20 to participate using their own accustomed digital assets, while the loosely coupled nature of Douglas AMC enables the operator to provide members within the business alliance system with technical empowerment, financial empowerment, and Business Empowerment.

E. Business Alliance Incentives

By connecting different public chains and business-oriented application chains, Douglas AMC will enable members of business alliances, technology development teams and on-chain resource users to connect, allowing users to participate in the ecology flexibly in a self-organized community mode, realizing an adaptive mechanism that digital assets can be transferred in different chains, exchanged in different users and traded in different industries, and setting up a node program to stimulate users and industries that promote Douglas AMC.
