Advantages
Open and Easy to Use
Building an enterprise-grade distributed blockchain network is not easy. It requires not only in-depth knowledge of blockchain but also complex design and configuration, which is error-prone and costly.
- BCS can help enterprises deploy blockchain networks within only 5 minutes, reducing the development and deployment costs by as much as 80%.
- BCS hosts functions of full-lifecycle management and GUI-based smart contract coding, commissioning, and deployment. Customers using BCS can focus on the innovation and development of their own service applications.
Flexible and Efficient
- BCS supports multiple efficient consensus algorithms and deeply optimizes existing algorithms to achieve balance between security and efficiency.
- Consensus within seconds can realize 100,000 transactions per second (TPS), meeting service performance requirements.
- Blockchain ledgers are stored in the efficient elastic storage files, satisfying the demand of fast storing massive amount of user data.
- Nodes of multiple roles and members can dynamically join or quit consortium blockchains.
Cost-Effective
- Instance hibernation and waking at any time
- The Application Operations Management (AOM) service is used for comprehensive O&M on the BCS instances, providing system status, performance, and transaction monitoring, maintenance, and alarming to reduce O&M costs.
- The node scaling function greatly improves the cost-effectiveness.
Secure and Private
Comprehensive approach to blockchain security:
- The security system ensures stable and secure running of blockchains.
- The Hyperledger-assured security system prevents data tampering and protects privacy by means of certificate management and the blockchain structure of data.
- Innovative algorithms such as homomorphic encryption and zero-knowledge proofs provide further privacy protection.
- OSCCA-published cryptographic algorithms are used for encryption and decryption.
Trustworthy and Collaborative
BCS provides the Trusted Computing Platform to facilitate trusted cooperation between multiple parties. This platform has the following core features:
- Decentralized identity (DID) management, which is in compliance with the W3C DID and W3C verifiable credential (VC) standards. This feature lowers the threshold of trust and improves cooperation efficiency.
- Blockchain-based, trusted data sharing, which ensures trusted data flow between multiple parities, breaks data silos, and realizes data value.
- Confidential computing, which is based on blockchain, Trusted Execution Environment (TEE), and federated learning technologies. The raw data can be computed without being revealed, ensuring data privacy.
