Compared with traditional technology, blockchain is not superior in solving efficiency problems, and its greatest role is to solve trust problems.At present, many blockchain companies focus on the concept of trusted electronic certificates (blockchain certificates). For example, listed companies previously reported by Odaily, the blockchain business it develops is copyright deposit certificate.
On March 30, the "Network Office" announced the first batch of
Among them, Odaily found that there is a filing company whose business is blockchain trustworthy certificate storage. The name of the enterprise is "Suzhou Tongji Blockchain Research Institute Co., Ltd.", and the filing service is "Wutong Chain".
At present, the "Wutong Chain Certificate Deposit Platform" developed based on the Wutong Chain has been implemented and connected to the Xiangcheng Notary Office of Suzhou City, Jiangsu Province.

Alliance chain made by Tongji University
Wutong Chain White Paper
, Indus Chain is an alliance chain mainly developed for enterprise and institutional blockchain application scenarios. In May 2018, Tongji University joined forces with HNA Technology, Ouyeel Finance, Bank of Shanghai, China UnionPay and other enterprises to jointly launch Wutong Chain, and the underlying technology was developed by Suzhou Tongji Blockchain Research Institute.
At present, the Wutong Chain adopts an open source method, jointly managed, developed and maintained by the research institute and the community, and mainly focuses on industries such as finance, supply chain, education, health and culture.
In terms of technical architecture, Wutong Chain consists of the underlying platform and external application modules based on the underlying platform. The underlying platform consists of network services, data storage, rights management, security mechanisms, consensus mechanisms, smart contracts, and other parts. The external application module can be systematically customized and provide development APIs for different application scenarios.

The data during the running period is stored in the memory of the node. When it is necessary to record a new block, you can choose the appropriate persistence scheme for different data to save the block. Currently, the Wutong Chain has implemented the use of LevelS storage data, with support for extending to use public cloud storage
Authority management is responsible for the management of all node permissions participating in the Qiaotong chain. Different permissions are granted to different nodes. In addition, the access and read and write permissions of the Wutong chain are also responsible for the authority management module. Only authorized users can access the data on the chain .
In addition, Wutong Chain adopts the Docker container solution to provide an isolated security environment. The smart contract runs in the Docker container and can be isolated from the chain system, ensuring the security of contract execution. In addition, Wutong Chain also combines the deployment, development and operation of blockchain technology positioning, key tasks, technological innovation, and industrial development to provide governance and operation and maintenance support for the blockchain system, and can monitor the operating status of the entire network in real time.official websitesecondary title
Application: certificate storage platform + certificate platform
In the white paper of Wutong Chain, its application scenarios are supply chain finance, super medical ledger and trusted electronic certificate platform.

It shows that there are currently two landing applications of the Wutong Chain - the certificate storage platform and the certificate platform.
With the development of science and technology, the electronicization of vouchers (bills, insurance policies, receipts) generated in people's daily life has become a new trend. However, traditional electronic data has problems such as easy forgery, tampering, and deletion.
The Wutong chain certificate storage platform mainly stores information such as electronic certificate hash value and time stamp, and the data is synchronized to each node in real time, and written into the alliance chain after the node consensus. The business will not be affected by the risk of a single node service, thus ensuring data open, transparent, safe and credible. Key features include:
Cloud verification: Provide services and methods for enterprises and cardholders to verify electronic certificates. Enterprises that use third-party escrow services can compare the electronic certificate with the summary of the electronic certificate obtained from the blockchain to verify the authenticity of the electronic certificate after obtaining the electronic certificate.
In addition, the application scenarios of the platform can gradually extend from electronic purchase orders to general financial business processes such as electronic contracts, electronic invoices, electronic insurance policies, specific financial vouchers and certificates, and even more pan-financial fields.
At present, the Wutong chain certificate storage platform has been implemented, and its users include the Xiangcheng Notary Office of Suzhou City, Jiangsu Province.
Another application of the Wutong chain is the Wutong chain certificate platform. It is a trusted electronic certificate system built on the Wutong Chain, which can solidify the issued certificates and course information such as related institutions in real time, ensuring that the data is complete, tamper-proof and traceable.
