Financial security is an important component of national security and a crucial foundation for stable and healthy economic development. The trading system is the fundamental core system of the securities industry and a key information infrastructure for national financial security. Currently, it is mostly built using foreign technology and heavily relies on foreign suppliers, facing the risk of being "stuck". As the substitution of information and innovation in the securities industry enters a deep water zone, how to achieve comprehensive substitution of information and innovation in the core trading system of securities companies poses significant challenges to the work of information and innovation. In 2023, Guotai Junan will take the lead in completing the construction of a full chain and full stack distributed securities core trading system (see figure). The company has independent intellectual property rights, advanced substitution, performance indicators, and disaster recovery capabilities that have reached the international first-class level. It is the first in the industry to achieve large-scale full stack innovation applications in complex production scenarios with complete core transactions and full links. It has successfully explored a smooth implementation path for a large-scale core system and driven the industry's innovation work to deepen. Inclusive finance enables ordinary customers to enjoy a fast trading experience. Leading the transformation and taking the lead in upgrading the core transaction technology architecture. Jointly research and build, drive the transformation of information and creative products from "usable" to "easy to use" on the industry side.


Autonomous and controllable, advanced substitution
Guotai Jun's secure chain full stack Xinchuang distributed securities core trading system fully realizes independent and controllable core trading, horizontally upgrades the full chain Xinchuang from mobile, desktop, branch, access services, core trading to disaster recovery, vertically replaces the full stack Xinchuang from servers, switches, storage to operating systems, databases, virtualization software, and middleware, and fully adopts Kunpeng servers, Huawei switches, Huawei storage, Galaxy Kirin operating system, GoldenDB distributed database, OceanBase distributed database, SmartX virtualization software, AMI distributed message middleware, as well as Xinchuang KCXP and KCBP middleware.
Guotai Jun's secure chain full stack Xinchuang distributed securities core trading system achieves advanced substitution while being independently controllable, and its performance reaches the international first-class level.
The core transaction realizes the decoupling of trading and clearing, and has the characteristics of low latency, high throughput, high reliability, and smooth horizontal scalability. The transaction has been upgraded to a full stack Xinchuang distributed low latency architecture with message bus as the core, resulting in a 90 fold increase in transaction speed. The throughput capacity has been increased by 8 times, and the capacity has been increased by 6 times. A low latency core trading system has been implemented on the Xinchuang equipment, allowing ordinary customers to enjoy a fast trading experience, improving customer commission rates and transaction efficiency, and achieving inclusive finance. The all business centralized clearing platform adopts full stack Xinchuang technology, based on a distributed architecture such as one household, multiple tenants, sharding, and virtualization cloud platform, covering standardized securities business, personalized company business, over-the-counter business, etc. It supports day end batch clearing, real-time daytime clearing, and multi batch clearing modes, and can clear according to different dimensions such as files, markets, varieties, and currencies. Implementing real-time credit trading night market commission based on transaction clearing decoupling technology architecture, providing multi-mode and multi-dimensional clearing services, supporting public bank insurance, proprietary business QFII、 Innovation in clearing businesses such as income swaps and interbank bond market counter services.
The mobile end is based on the HarmonyOS operating system, and it is the first application market to be launched in the industry, taking the lead in replacing mobile based innovation. Design a modular and pluggable front-end architecture based on technical and business components, which solves the problem of traditional securities app iteration delivery efficiency, functional experience, and flexible updates that cannot be achieved simultaneously. By combining native and mini programs, as well as H5 diversified mixed development, we ensure the stability and security of the app while achieving rapid launch and flexible application of business functions.
The desktop is based on a self-developed cross platform innovation framework, with an overall architecture design that is platform based, low coupling, modular, plugin based, multilingual, cross platform, and cloud based, thus achieving one-time development of desktop trading software and multi platform operation. By adopting innovative solutions such as memory sharing and asynchronous calling, the performance has been improved by 200%. The first desktop trading software in the industry to support Kirin and Tongxin UOS innovation systems.
The network achieves full replacement of information and innovation equipment, full adaptation of application systems, and full coverage of service channels. Based on the Xinchuang framework, we provide counters and self-service through SDWAN network and intelligent applications, and have established the industry's first fully Xinchuang branch for business processing.
The Internet access service exclusively adopts the SSL gateway, cooperative signature service and CA certificate of multi commercial password access technology to ensure the security and high availability of access. Adopting the Xinchuang Cloud Container Platform for deployment, the system resources are flexible and scalable, ensuring easy and rapid access and expansion. By using ProtoBuf serialization protocol and asynchronous bidirectional streaming technology, efficient data compression and fast parsing are achieved, improving access performance, achieving full link tracking, fuse current limiting, and monitoring and warning, with stable and controllable access.
The transaction disaster recovery system is based on the high-speed message bus one send multiple receive and state machine mechanism to achieve high availability mechanism innovation in two locations and three centers. Switching RTO within the same city takes less than 10 seconds, RPO=0。 Remote disaster recovery (RTO)<1 minute, RPO<1 second, and disaster recovery capability increased by 30 times, solving the long-standing problems of high availability dependent databases for core transactions, long interruption times for disaster recovery switching, and frequent data loss in the industry. The industry has pioneered a real-time backup mechanism for heterogeneous trading systems, which allows customers to seamlessly switch back to the original system within 3 minutes to continue providing services and maintain the bottom line of core trading and innovation substitution for safe production.
