Blockchain and power generation

1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

2. The difference between code chain and blockchain:
blockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".

3. The core function of blockchain technology is not to rely on the center or the third-party organization to ensure the authenticity and credibility of data, break the trust barrier, greatly rece the trust cost of business development, and promote the efficient development of business. At present, the application of blockchain in the energy field has begun to take shape. Some developed countries in Europe and the United States and a few high-tech companies have begun to try to apply blockchain technology to the energy field

for example, in energy ecation, the application of blockchain in the field of energy trading can focus on the establishment of distributed trading and supply system.

4. At present, the concept and construction mode of blockchain has been relatively mature, and some progress has been made in the field of application analysis of energy utilization. Specific applications include: energy trading and supply based on smart contract, ownership of information and establishment of distributed transaction records, etc.

5. Blockchain can provide an intelligent system platform for carbon emission certification and measurement
the essence of blockchain decentralization helps to solve some security problems in physical information systems
blockchain can provide a low-cost, open and transparent system platform for the transaction of virtual power generation resources
blockchain can provide a decentralized system platform for multi energy systems
jinwowo network technology will use blockchain technology to promote the legalization of big data business.

6. What is blockchain technology

before discussing how to apply blockchain in daily life, let's talk about what blockchain is and how it works

blockchain is an open distributed database, which is essentially a computer file used to store information (data)

the name of blockchain comes from its structural characteristics: the file is composed of data blocks, and each block is linked to the previous block to form a chain. Each block contains data, such as transaction records and records when the block was edited or created. Information (data) is stamped with time stamp, which is the origin of blockchain

it is crucial that, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and data is completely copied (distributed) on multiple computers

because it is a decentralized way to store and access data, it becomes extremely secure. Different from the centralized database, the attacker does not have a single entry point, so the data security is more guaranteed<

in addition to the two characteristics of decentralization and security, blockchain has become a leading technology which is different from other technologies:

tamperability: once entering the blockchain, any information can not be changed, even the administrator can not modify this information. It makes blockchain easy to audit

accessible: all nodes in the network can easily access information

no third party: blockchain can help point-to-point transactions, so whether you are trading or exchanging funds, you do not need the approval of a third party. Blockchain itself is a platform

the impact of blockchain technology

first, the open and tamperable nature of blockchain technology makes it possible to decentralize the trust mechanism. It has the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, bills, warehouse receipts and fund shares, can be integrated into the blockchain ledger to become digital assets on the blockchain, which can be stored, transferred and used in the blockchain Deal. It has a broad application prospect in the financial field. For example, it has typical applications in cross-border payment, insurance claims, securities trading, bills, etc

Second, the current Internet of things ecosystem relies on the centralized network management architecture, and all devices are connected through the cloud server. With the expansion of the network scale, the infrastructure and maintenance of centralized cloud servers, large servers and network equipment will occupy a high cost

in the decentralized Internet of things, blockchain is a framework to promote transaction processing and cooperation among interactive devices, and each device on the network can operate as an independent and micro business entity< Third, public service is a factor to promote economic growth and social progress. The supply of public service has an important impact on various subjects, systems, cultures, attitudes and behaviors in the process of political, economic and social development. The traditional notarization relies on the government, and the limited data dimension and the historical data information chain that has not been established often lead to the government and schools unable to obtain complete and effective information. Using blockchain, tamper proof can be established. In the fields of digital rights, intellectual property rights, certificates and public welfare, new authentication mechanisms can be established to improve the management level of public services.

7. The problem of distributed access to the Internet has been solved. Now the power grid is basically centralized, while the blockchain is decentralized, which is consistent with the current photovoltaic power generation. Photovoltaic power generation is decentralized and multi-point.. The access to the power grid is uncertain and its performance is unstable, or some intervention may damage the power grid. In the algorithm of blockchain, there is consensus algorithm, which can solve this problem well,
