㈠ How to define blockchain and what are its application scenarios
Many people now think that blockchain is a universal technology that can do anything. Make blockchain technology a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
Blockchain is a method that connects data blocks in an orderly manner and cryptographically ensures that they cannot be tampered with, Unforgeable distributed ledger (database) technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.
Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises,Upstream and downstream suppliers, financial institutions, etc., core enterprises issue accounts receivable certificates to their suppliers. The bills can be transferred between suppliers after being digitized on the chain. Each level of supplier can use the digital bill certificate to achieve the corresponding amount of financing. .
Digital Government Affairs
Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.
Evidence-based anti-counterfeiting
Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.
Data services
Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will be effectiveReduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this was the arrival of a new era, and the past It has become a classic, and some people say that it is all hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. “Smart contracts cannot simply be understood as electronicContract refers to a process, from conclusion of contract to confirmation to final execution. "Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but an integration of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, smart contract and other computer technologies. New application model. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to the characteristics of "decentralization" and "distribution" With advantages such as "automatic data storage", "traceability", "tamper resistance", and "openness and transparency", blockchain technology can effectively solve the problems of data authenticity, security and openness in the data field. A data management environment to prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote efficient sharing and application of data. In the process of practical exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions. Empower public resource transaction management services.
Promote transaction data sharing and transaction witness
Promote transaction data sharing
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. During the bid evaluation process, it is difficult to verify the off-site performance provided by the bidders, and the same personnel are duplicated. Problems such as difficulty in troubleshooting as a project manager and low cost of breach of trust by transaction entities. Establishing a cross-regional entity database based on blockchain can well alleviate the above problems.
The distributed ledger features based on blockchain can Effectively guaranteeing the real-time or quasi-real-time sharing of data, it can reduce repeated entry operations of subject information; the use of blockchain information that cannot be tampered with can ensure the authenticity of the data flow process on the chain. The performance of bidders in the regional alliance is directly taken from the data on the chain. This makes it impossible to hide false performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness
The document "Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" (State Office Letter [2019] No. 41) points out the need to optimize witness, venue, Information, archives, expert extraction and other services. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing strength, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witnessing system is easy to collect data afterwards Be tampered with, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to verify each transaction The data generated in the link are solidified and stored as evidence, using timestamp technology and summary algorithms., Electronic signature technology accurately records the time, content and data source of data generation. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding enterprises
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote financial services for bidding companies
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solving the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustainable profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become the challenges faced by many small and medium-sized enterprises in bidding activities.The problem. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data credibility but also reduces the risk of corruption. The entire system relies on a centralized authority.
Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What economic benefits can blockchain have?What about applications?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.
Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since digital advertising traffic fraud causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
What is blockchain If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. So in the Internet, a place where data is exploding and information is exploding, how can there be such aThe place will be like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
㈡ Can my cloud be flashed?
No. Because on July 19, 2019, my cloud companyNotice that on August 19, 2019, the operation of distributed network, Yunhui Magic Box, and My Home Cloud services will be stopped.
My Home Cloud is equipped with Cortex-A53 architecture and equipped with 8GB ROM and 1GB DDR3 memory. It has a built-in 2TB 5700 rpm 32M SATA3 hard drive. It supports Gigabit network and is equipped with an external interface. There is a USB3.0 and a USB2.0 expansion interface. Although the performance is not high-end, there are no obvious shortcomings for a home NAS.
(2) How to combine blockchain with distributed storage. Extended reading:
Product functions
My cloud products will differentiate Blockchain and distributed storage are combined to store user data on the hard drive. The data is first encrypted and then broken into pieces through algorithms and dispersed to other users' hard drives. The blockchain can record the idle space contributed by each user in a credible way, and establish a trusted transaction platform between storage contributors and users.
By sharing idle space, users can earn CBC points. New users can earn additional CBC points by purchasing equipment and staying online. Each CBC point corresponds to a certain amount of storage space and bandwidth.
㈢ Blockchain technology and applications: a technological revolution in the future
Blockchain technology originated from "Bitcoin: A Peer-to-Peer Electronic Cash System" proposed by Satoshi Nakamoto 》, where "block" means that each information block contains a timestamp. Information blocks containing timestamps are connected to each other, and the chain of information blocks formed is a "blockchain".
Blockchain is a technical solution that collectively maintains a reliable database in a decentralized and trustless manner. From a data perspective, blockchain is a distributed database in which a single node or multiple nodes cannot intentionally change data records. Its distribution is reflected in the distributed storage and distributed recording of data. From a technical perspective, blockchain technology is an emerging technological achievement resulting from the integration of multiple technologies. After the development and improvement of a combination of multiple technologies, it forms a more efficient way of recording, storing and expressing data.

㈤ Blockchain distributed storage: a new storage model for ecological big data
Blockchain is undoubtedly the most beautiful word in 2019. It shines in the field of technology and in the physical world. The industry is star-studded.
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 cast in a layer of gray. But now, blockchain is closely connected with the integration of the real economy and has become a strategic technology for the country. The word instantly shines with passionate red and vibrant green.
"Industrial Blockchain" has emerged as the times require."Biology" is another hot word after "Internet". The core is that blockchain must be integrated with real industries, and the right way is to move away from virtual reality and allow blockchain technology to find more business scenarios.
The essence of the blockchain is a database, and it uses a distributed storage method. As a blockchain practitioner, today I will talk about the sparks generated by the collision of distributed storage of blockchain and ecological big data.
Most of the current storage is centralized storage, which is stored on traditional centralized servers. If the server goes down or malfunctions, or if the server ceases operations, a lot of data will be lost.
For example, the pictures we post in WeChat Moments, the videos uploaded on Douyin, etc. are all centralized storage. Many friends will store things on the Internet, but when they open it one day, the web page will display 404, which means that the stored things have disappeared.
Blockchain, as a distributed database, can solve this problem very well. This is determined by the technical characteristics of the blockchain. 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 the efficiency of data flow, break down data silos, and create a new storage model.
Ecological big data is actually closely related to our daily lives, such as daily weather forecasts, traceability data of agricultural products we eat, etc., which are all part of ecological big data. To talk about this combination, first let's take a look at the characteristics of ecological big data storage.
With the development of the Internet, currently, ecological big data has the following characteristics in terms of storage:
From the perspective of data scale, the volume of ecological data It’s huge, and data has jumped from the TB level to the PB level.
With the development of various sensor technologies, satellite remote sensing, radar and video sensing technologies, data not only comes from traditional manual monitoring data, but also includes aviation, aerospace and ground data. Together, they have generated a massive amount of ecological data. environmental data. In the past 10 years, ecological data has grown by hundreds of terabytes per year.
Ecological environment big data requires a combination of dynamic new data and historical data for processing, and real-time continuous observation is particularly important. Only by processing and analyzing these dynamic new data in real time and combining them with existing historical data can we unearth useful information and provide scientific decisions for solving ecological and environmental problems.
For example, in the current urban construction, the ecological environment restoration and ecological model construction advocated require a large amount of ecological big data to be used for analysis, modeling and plan formulation. However, currently a lot of historical data disappears due to improper storage, resulting in the loss of data value.
Since ecological big data has these characteristics, thenSo what are its storage requirements?
Currently, 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 leakage occurs due to external network attacks by hackers and improper human operations. External attacks include data transmission attacks on static and dynamic data, data content attacks, data management and cyber-physical attacks.
For example, many massive data for wild ecological environment monitoring require network transmission, which increases the risk of cyber attacks. If it involves some ecological and environmental data used by the military, if these data are obtained by hackers, they may infer some information about our military or obtain sensitive ecological and environmental data, with disastrous consequences.
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 when different types of ecological environment big data are connected, collided and shared can the value of ecological environment big data be released.
Taking the current smart city construction as an example, many cities are establishing agricultural information big data centers on intellectual property, germplasm resources, agricultural materials, agricultural products, pests and diseases in all aspects and dimensions to provide agricultural products with Supply and marketing provide full information services. 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 from meteorology, water conservancy, ecology, land, agriculture, forestry, transportation, social economy and other departments, involving multi-field, multi-sector and multi-source data. Although these departments have currently established their own data platforms, these platforms are not connected to each other and are just isolated data islands.
Secondly, the relevant departments cannot share the data because they are unable to track the trajectory of the data and are worried about the ownership of the data’s interests. Therefore, in order to explore the potential value hidden behind ecological big data, achieving secure data sharing is the key, and it is also the premise and basis for the value of ecological big data.
Ecological big data is hard-won and is the collective wisdom of research institutes, enterprises, individuals and other social sources.
Among them, many ecological big data involve the protection of intellectual property rights. However, the current centralized storage cannot guarantee the protection of intellectual property rights and cannot perform traceability management of data use, which can easily lead to the infringement of intellectual property rights and the leakage of private data.
These are the storage needs of ecological big data. Today, with the rapid development of industrial blockchain, the distributed storage of blockchain can provide a new storage method for ecological big data storage. This core premise is the distributed storage of blockchain, non-tampering and data tracking features.
Using blockchain as the underlying technology, build such a platform to specifically store ecological big data. You can set up node management, storage management, user management, license management, business channel management, etc. Implementation of the underlying services of the blockchain network that provides high availability and dynamic expansion for upper-layer business applications. In the application layer of this platform, API interfaces can be built to make the use of the entire platform flexible and scalable. Blockchain distributed storage has the following characteristics:
Utilizing the distributed storage of blockchain can achieve truly secure storage of ecological big data.
First, data is never lost. This is particularly friendly to the historical data of ecological big data, making it convenient to call and compare new and old data.
Secondly, data is not easily leaked or attacked. Because the data is stored in a distributed manner, if there is an attack, only the data fragments stored in some nodes can be obtained, and the complete data information or data segments cannot be completely obtained.
Blockchain can realize the storage and confirmation of ecological data, so as to avoid the infringement of intellectual property rights and achieve safe sharing. After all, the acquisition of ecological big data requires ecological workers to be stationed in the wild all year round to extract data.
Ecological big data is hard-won and is the hard work of many ecological workers. It needs to be protected by property rights, so that the data can reflect its application value and commercial value, and the work motivation of ecological workers can be protected. They can go deep into the front line and collect more high-quality big data.
At the same time, the use of blockchain's data security sharing mechanism can also break down data barriers in departments such as meteorology, forestry, and wetlands, and build a safe and reliable data sharing mechanism to make data flow more valuable.
Nowadays, some ecological workers will tamper with ecological data for personal gain. If you use blockchain technology, it is not so easy.
Using encryption technology, the stored data is placed on a distributed storage platform for encryption processing. If the ecological big data changes, the platform can record its different versions to facilitate subsequent tracing and verification.
This protection mechanism mainly takes advantage of the non-tamperability of data to meet the requirements for data security in various business processes that use ecological big data.
The blockchain can provide secure monitoring of data, record the operation logs of the application system and the operation log data of the database, encrypt and store them on the system, provide log warning functions, and browse through the blockchain for abnormal situations The device is displayed to facilitate timely detection of illegal operations and the provision of evidence.
The above is the role that distributed storage of blockchain can play in ecological big data. In the future, there will definitely be many platforms for ecological big data storage.
Ecological big data is an important basic data 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 industry. The development of blockchain.

㈥ How does blockchain achieve distributed consensus?
The entire human society can only constantly find a balance between distribution and consensus. The two have shown an alternating situation in the past. The distribution is constantly iterating, and each new cycle will inherit the results left by the previous cycle. As a result, human beings can continue to reach a larger scope and higher level of civilization.
The distribution period is mainly characterized by the development of individual interests, but this does not mean that there is no centralized decision-making; the consensus period adopts centralized management that prioritizes efficiency, and distribution will be appropriately considered for overall stability and other demands.
The emergence of distribution often occurs at the end of consensus. At this time, due to uneven distribution and lack of incentives, the public has been unable to obtain further benefits, and the development of the entire society has also slowed down significantly. At this time, we prefer to use distribution Overturn the original small-scale consensus.
Significance
The reason why the Internet can play a huge role in social development lies in the establishment of a decentralized and distributed network and the The use of the TCPIP protocol, which promotes equality and realizes resource sharing, eliminates the problem of over-concentration of information and decision-making caused by centralization in the industrial age.
The emergence of blockchain is based on the prosperity created by the Internet. Through the technological innovation brought by the new distributed ledger, there is an opportunity to further promote the transfer of value. This can solve the obstacles encountered by today's Internet in the process of interconnection and interoperability entering deeper areas, and once again enhance the level of human prosperity.
