Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The invention is described in further detail below with reference to the attached drawing figures:
as shown in fig. 1, the method for sharing data of geological work result based on blockchain technology according to the present invention includes: step 1: a user uploads project result data of a geological project, a corresponding identity authentication strategy and an intelligent contract to a block chain platform; step 2: after the user performs identity authentication through the block chain platform, the project result data is consulted for the first time to obtain, and the extraction process is recorded into the platform block chain; and step 3: other geological institutions or social individual users perform identity authentication through the block chain platform, the users who succeed in identity authentication obtain the project result data, and the extraction process is recorded into the platform block chain; and 4, step 4: and (3) newly adding result data by referring to the project result data by the other geological institutions or social individual users, and repeating the step 1 to upload the newly added result data to the block chain platform.
In this example, before further details of the example are described, the terms and terminology referred to therein are described as follows:
(1) a chunk chain is a storage structure for encrypted, chained transactions (in the present invention, download sharing) formed by chunks. For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.
(2) The hash function, also called hash function, is to transform an input with any length into an output with a fixed length by a hash algorithm, and the output value is the hash value. Has unidirectional property and no collision. Common hash functions are: SHA-1, SHA-256, SHA-512, MD5, etc.
(3) And the block chain network is used for bringing the new block into a series of node sets of the block chain in a consensus mode.
(4) And after the verification of the nodes of the whole network is passed, all the nodes update own block chain accounts. The commonly recognized mechanism can be PoW, PoS, etc. in current blockchain technology.
(5) The identity authentication strategy is an automatic identification strategy constructed according to certain identity information, and gives access authority to a part of users, so that the users can obtain data, other users are limited from accessing the data, and the information is ensured not to be obtained or tampered by illegal users. The method is suitable for statically distributing the authority of the user.
(6) Asymmetric encryption, specifically, a public key is disclosed to the outside for encryption operation; the other key is a private key which is kept secret from the outside and is used for decryption operation. In the encryption and decryption processes, the public keys and the private keys are in one-to-one correspondence, and data encrypted by one key can only be decrypted by the corresponding key. Compared with a symmetric cryptosystem, the data of the public key encryption system is encrypted only by mastering a public and private key pair, so that the management is convenient; the key encrypted by the public key can be transmitted in a public channel without being seen by an attacker; what is important is that the public key cryptosystem can be used to carry out digital signature and identity verification.
(7) The intelligent contract, also called chain code or application code, is a program deployed in a node of the blockchain network, and the node executes the intelligent contract called in the received transaction to update or query the key value of the state database for data.
(8) Consensus, a process in a blockchain network, for agreeing on transactions in blocks among a plurality of nodes involved, the agreed blocks to be appended to the end of the blockchain, the mechanisms to achieve consensus including Proof of workload (PoW, Proof of Work), Proof of rights and interests (PoS, Proof of stamp), Proof of equity authority (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), etc.
