Product advantages

Open sharing

·Based on the mainstream open source blockchain technology hyperledger fabric, it natively supports blockchain applications and data that meet the hyperledger fabric standard; Code development achievements continue to contribute to the open source community to ensure the openness and transparency of technology.
·In the future, more excellent blockchain technology systems will be integrated to create an open, shared, comprehensive and unified blockchain application ecosystem for users.

High safety

·SGX chip level encryption technology based on elastic bare metal server (DPCA) realizes advanced security protection of blockchain key keys.
·Support encryption and decryption based on national secret algorithm.
·A governance system for multi enterprise alliance chain is built in to ensure that the collaboration process between enterprises is controllable and credible.
·Provide multi-dimensional network isolation, network access control and attack protection for business participants.
·Each participant has independent CA services to meet the needs of the enterprise's independent certificate system.
·With built-in risk control and operation audit functions, it is not afraid of the risk of "Oolong index".
·Universal chain financial cloud has the level 4 Qualification of equal assurance, providing a higher level of security deployment platform for blockchain.
·Users can further use the 17+ security products, 9+ security solutions and 14+ security services provided by universal chain to establish a comprehensive security protection system for the upper business applications of blockchain.

High availability

·The whole link of the system realizes high availability design, including blockchain nodes, service management and control, container clusters, cloud based resources, etc., to ensure business continuity.
·The underlying storage of blockchain ledger data has extremely high reliability (99.99999999%), and can realize storage elastic expansion without application perception and interruption.

Easy to use

·With one click operation, we can quickly obtain a complete enterprise blockchain network.
·Provide graphical and rich management and operation and maintenance functions to help users easily configure, deploy, manage and monitor multiple blockchain networks owned by enterprises, and do not need to be proficient in the underlying technical details of blockchain, reduce the threshold of blockchain use, and reduce the pain caused by technical complexity.
·Avoid excessive investment in the construction, operation and maintenance of the underlying blockchain and basic resources, and let enterprises focus on business application innovation on the blockchain.
·Provide blockchain SDK, blockchain application development rest API and operation guide, which greatly reduces the user's use threshold.

High performance

· High performance cloud servers (including elastic bare metal dragon servers), high bandwidth networks, high concurrency and high throughput storage technologies based on universal chain release the performance potential of blockchain.

Global deployment

·The data centers of the universal chain are widely distributed all over the world, helping users realize the global deployment of business systems.
·Based on the mature overseas compliance processes and best practices of universal chain, ensure the safe and compliant operation of business systems.

Cosmic Interstellar Public Chain

·High performance: Byzantine fault-tolerant consensus algorithm implemented independently optimizes the efficiency of parallel processing, and the transaction performance of depository service is up to 25000 transactions per second.
·High security: carry out identity authentication and authorization management for all participants, and realize end-to-end encrypted transmission of the whole chain and connection layer identity authentication to prevent performance attacks; In terms of encryption, it supports pluggable cryptographic algorithms, can flexibly formulate the corresponding cryptographic system, supports state secret algorithms and hardware encryption devices, and provides privacy protection means at different levels, such as one-time encryption and multi-party signature; Consensus protocol prevents malicious attacks on nodes.
·High availability: it supports cross-border deployment and automatic adaptation to network delays. The consensus state of the node and the blockchain data are automatically restored synchronously, and the node services are automatically routed.
·For data privacy and security, users can choose to link plaintext data, or encrypt the linked data in the way of symmetric encryption. At the same time, it supports the privacy sharing model, that is, the encryption key is encrypted by another private key, and the encrypted plaintext and encrypted secret key are saved on the chain. The private key is managed through the asymmetric secret key export function, providing a service-oriented programmable interface. Business participants obtain different secret keys for decrypting business data according to their different business scope and sharing scope.
·Business semantic Customization: the alliance participants agree on the business data structure, configure the data type definitions agreed by many parties to the alliance chain, provide SDK and rest service interfaces to analyze the corresponding business data content, and support update, modification and adjustment.
·Cross network deployment, blockchain nodes can be deployed across the cloud platform according to the needs of alliance participants, that is, some nodes participating in the consensus run on the universal chain platform, and some nodes participating in the consensus run in the user environment. If you need to deploy across the network, please contact the background operation and maintenance.
·To ensure network security, multiple independent blockchain nodes are deployed in the VPC network to ensure that users' blockchain nodes operate in a secure network environment.

Product architecture

Cosmic Interstellar Public Chain Blockchain service supports users to realize cross organizational business collaboration and transaction network, that is, the establishment of alliance chain. At the same time, Multi Chain isolation is realized based on technologies such as business channel: that is, ledger data is shared only among nodes with verifiable membership in the business channel and will not be disclosed to other members of the blockchain network.

Product function architecture

 ·Infrastructure layer: support public cloud, and further support deployment forms such as proprietary cloud and hybrid cloud in the future.
·Cloud resource layer: it includes the cloud basic resources required by blockchain services and upper tier applications, including ECs, VPC, NAS, SLB, etc.
·Blockchain platform service layer: built on the kubernetes cluster of universal chain container services, it implements baas basic services such as resource creation, management and control operation and maintenance, and security governance. The blockchain engine supports hyperledger fabric (version 1.2) under the Linux foundation, and will support more underlying blockchain technology types in the future.
·Blockchain application middle tier: This is the reference architecture, which mainly realizes the connection between baas and business.
·The overall architecture also includes various cloud services such as security management and operation management that may be used by blockchain services and business applications.
