Blockchain, deservedly the most beautiful word in 2019, shines in the field of science and technology, and is shining in the physical industry. The 1024 speech in 2019 gave the word blockchain a new look. In the past, it was always associated with pyramid schemes and fraud, and the word “blockchain” was always grayed out. But nowadays, the blockchain is closely connected with the real economy and has become a national strategic technology. The word instantly shines with passionate red and business-rich green.
1. Centralized storage VS distributed storage 
Most of the current storage is centralized storage, which is stored in traditional centralized servers. If the server goes down or fails, or the server stops operating, a lot of data will be lost. For example, the pictures we posted on WeChat Moments, the videos uploaded on Douyin, etc., are all centrally stored. Many friends will store things on the Internet, but one day after opening, the web page displays a 404, which means that the stored things are gone. Blockchain, as a distributed database, can solve this problem well. This is determined by the technical characteristics of the blockchain. The digital records on the blockchain cannot be tampered with or forged. Smart contracts allow everyone to collaborate more efficiently to establish a credible digital economic order, which can improve data flow efficiency, break data silos, and create a new storage model.
Second, the storage requirements of ecological big data
- Strongly secure storage; At present, ecological big data is facing serious security risks, and strong secure storage is imperative for ecological big data. The security of big data mainly includes the security of big data itself and the security of big data technology. For example, in the data storage of big data, data information leaks due to external networks*** and improper human operations. External *** includes data transmission*** of static data and dynamic data, data content***, data management and cyber physics***. For example, many large amounts of data for field ecological environment monitoring require network transmission, which increases the risk of network security. If some military-use ecological environment data are involved, if these data are obtained by police, some information of the Chinese military may be inferred, or the sensitive ecological environment data may be obtained, with disastrous consequences.
- A safe and shared storage mechanism; the commercial application of ecological big data requires the integration of data from multiple sources of society such as governments, enterprises, and scientific research institutes. Only by connecting, colliding and sharing different types of ecological environment big data can the value of ecological environment big data be released. Taking the current smart city construction as an example, many cities have established large data centers for agricultural information such as intellectual property rights, germplasm resources, agricultural materials, agricultural products, and pests and diseases in all aspects and dimensions to provide full-process information services for agricultural production, supply and marketing. The construction of such a big data center is inseparable from the sharing of ecological big data among various departments. However, ecological big data sharing faces huge challenges. First of all, my country's ecological environment big data includes big data in other sectors such as meteorology, water conservancy, ecology, land, agriculture, forestry, transportation, social economy, etc., involving multiple fields, multiple departments and multiple sources of data. Although these departments have established their own data platforms, these platforms are not connected to each other and are just data islands. Secondly, because the relevant departments cannot track the trajectory of the data and worry about the ownership of the data, they cannot realize the sharing of data. Therefore, in order to tap the potential value hidden behind the ecological big data, the realization of secure data sharing is the key, and it is also the prerequisite and basis for the value of ecological big data.
Third, the new storage model brought by the blockchain
In today's rapid development of the current industrial blockchain, the distributed storage of the blockchain can provide a new storage method for ecological big data storage. This core premise is the distributed storage, immutability and data tracking characteristics of the blockchain. Use the blockchain as the underlying technology to build such a platform to store ecological big data. Node management, storage management, user management, license management, business channel management, etc. can be set up. To provide high-availability and dynamically expanding blockchain network bottom-level services for upper-level business applications. In the application layer of this platform, API interfaces can be built to make the use of the entire platform flexible and extensible. - Data security storage; the use of distributed storage of the blockchain can realize the safe storage of real ecological big data. First of all, data is never lost. This is particularly friendly to the historical data of ecological big data. It is convenient to call new and old data and
ecological big data is an important basic material for smart city construction. Using blockchain technology to create a relevant ecological big data storage and management platform can ensure The safe storage and effective sharing of ecological big data contribute to the construction of smart cities and promote the development of industrial blockchain.
