DAEXs core provides unified clearing and settlement services for individual and institutional clients, leveraging distributed ledger technology.

Ecosystem Protocol

A unified business protocol is the foundation for realizing business paradigms such as clearing-as-a-service, needing to adapt to diverse scenario requirements. Through rich abstract business models, it satisfies cross-platform on-chain data sharing. Therefore, the clearing ecosystem must have sufficiently generic, standard, and easily constructible methods of recording data. It should effectively represent various structured information and possess an open, customizable protocol to enable cross-platform and cross-chain requirements as the business scope expands. 
The ecosystem protocol standardizes the business information domains and formats preserved in the clearing and settlement ledger, the business states generated during the business process, the triggers and conditions for business state changes, and the involved update information. Since participants sign business agreements based on smart contracts using their identity accounts, the execution process receives objective technical endorsement from the blockchain system, including consistent execution of the agreement at each node (i.e., obtaining recognition by the business entity); accurate recording of the execution process and unalterable final results (i.e., executed business facts are irrefutable).

Ecosystem Structure

The inherent intermediary-free and tamper-proof nature of blockchain technology provides a foundational solution for value accumulation and circulation in the DAEX ecosystem. However, to realize a decentralized autonomous community ecosystem, besides the foundational platform needing good performance - i.e., achieving throughput matching business needs - the entire ecosystem infrastructure must achieve overall "consensus" through superior interoperability. This includes utilizing distributed file systems to improve data storage performance, optimizing consensus protocols to suit clearing and settlement models, enhancing the security and usability of digital asset tools based on multi-asset wallets, and providing service-oriented interfaces for quick access support, among other solutions. This gives the clearing ecosystems product portfolio the following advantages: 
(1) More Robust
It avoids the possibility of users privately managing and transmitting complete keys, and with users at the core, completes efficient accounting on the distributed ledger based on consensus on the chain. 
(2) More Diverse
It extends the scalability of blockchain, supporting rapid transactions of multiple assets; meanwhile, the upper-level basic services of the clearing chain can maintain original transaction depth while offering a rich business ecosystem of derivatives and smart assets. 
(3) More Reliable
The segmented key mechanism and trusted computing environment used by multi-asset wallets enhance asset security; simultaneously, the consensus mechanism based on clearing value factors ensures fair shared value incentives and authoritative punishment for fraudulent behavior.

Project Functionality

(1) Identity Registration
A globally shared identity registration service where users need to fill out necessary identity proof information and provide related credential materials. To simplify the process, third-party identity service providers access registration is supported.
(2) Verification Registration
Verification registration checks the registered identity and completes the encryption and persistent sharding of identity data. After verification, the identity chain only registers the encrypted identity information, i.e., the identity fingerprint.
(3) Credential Management
After completing identity verification registration, the mapping of identity credentials is immediately executed. That is, the synchronous binding of the clearing chain address and identity credentials is completed. Additionally, this phase also provides management services for the identity lifecycle, such as credential addition, updating, and revocation.
(4) Credential Authorization
Based on the trusted authentication of the identity chain, it realizes cross-chain, cross-application identity sharing services within and outside the ecosystem.
(5) Identity Verification
Authorized trading platforms and identity service providers can use the identity verification service to complete cross-checking and verification of user identity certification information and provide verification feedback.
