Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a scientific data sharing method and system based on a block chain technology.
Background
Blockchain features: (1) de-mediation: because of the distributed accounting and storage, the system does not have centralized hardware or management mechanisms, the rights and obligations of any node are equal, and the data blocks in the system are commonly maintained by the nodes with maintenance functions in the whole system. (2) Patency: the system is open, except that private information of the sharing parties is encrypted, the blockchain data is disclosed to all people, and anyone can query the blockchain data and develop related applications through the disclosed interfaces, so the whole system information is highly transparent. (3) Autonomy: the blockchain adopts a specification and a protocol (such as a set of publicly transparent algorithms) based on negotiation so that all nodes in the whole system can freely and safely exchange data in a trusted environment, the trust of 'people' is changed into the trust of machines, and any human intervention does not work. (4) The information is not tamperable: once the information is verified and added to the blockchain, it is permanently stored, and modifications to the database on a single node are not valid unless more than 51% of the nodes in the system can be simultaneously controlled, so the blockchain is extremely data stable and reliable. (5) Anonymity: because the exchange among the nodes follows a fixed algorithm, the data interaction is not required to be trusted (program rules in the blockchain can automatically judge whether the activity is valid or not), and thus, the sharing opponents do not need to trust themselves in a public identity mode, and the sharing opponents are very helpful for the accumulation of the credit.
In the sharing process of scientific data, a sharing platform is used as an intermediate platform party, and processes such as request processing, request forwarding, result forwarding, payment settlement and the like need to be completed, the shared data content inevitably passes through the sharing platform, and the data is used as a special product and has the characteristic of 'seeing and owning', so that the possibility that the data is reserved by the sharing platform exists in theory. If this event occurs, it has relatively serious consequences. On one hand, the sharing platform is used as an intermediary platform, so that serious untrustworthy emotion can be caused, and no user exchanges data through sharing; on the other hand, shared platforms possess large amounts of data, which can cause irreparable loss once compromised.
