Application of blockchain technology in carbon trading

1. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

A: application fields of blockchain technology

I. financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics

through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

4. Can not be trusted to play their own know that the threshold of easy currency transactions as long as 100 yuan, take a 100 yuan to try water

5.

China's blockchain instry ecology has initially taken shape, and the number of enterprises has increased rapidly. According to the white paper on China's blockchain instry in 2018 previously released by the information center of the Ministry of instry and information technology, as of the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has exceeded 450, and the instry has initially taken shape

the Ministry of instry and information technology proposes that the blockchain instry is still in the initial stage, and the positive value of technology is graally emerging, but there are still risks that can not be ignored in the development process, such as challenges to the current system and norms, technical loopholes, etc. The Ministry of instry and information technology proposed that it will accelerate the innovation and application of blockchain technology, especially strengthen the improvement of computing capacity, storage capacity and integration penetration capacity, build a good instrial ecology, and promote the healthy development of blockchain instry

6. I don't think so. The original God's mine is refreshed frequently, and there are many refresh points, so don't worry about others digging your mine

7.

The mechanism of mineral refresh in the original God is 72 hours (3 days) refresh. Four people form a team to dig the mine, and rotate every day. They can also dig all the mines of four people at one time, once every 4 days. But they still have to go to the blacksmith's place to make iron every day. Crystal ore is refreshed every 3 days, white iron ore is refreshed every 2 days, and iron ore is refreshed every 1 day

for the mining mechanism, there is no upper limit (or the upper limit is very high) for mining every day after the public beta, but the weapon experience materials obtained by forging in different ways at the blacksmith every day have a common upper limit of 300000 (equivalent to 120 crystal minerals, except weapons), which means that iron ore, white iron ore and crystal ore share the upper limit

extended data:

it is suggested that three people should take turns to dig one person's world's mine a day; Suppose we dig a on Monday; Dig B on Tuesday; Dig C on Wednesday; Thursday dig a; By analogy, there will be mines every day. Similarly, Xiaobian suggests that the resources with a brush of 48 hours should be mined once every three days

in the game of the original God, the more advanced the ore, the longer the refresh time. For example, for low-grade ore such as iron ore, the refresh rule is once a day; Pyrite, yeposhi and perlite are refreshed every two days, while crystal ores are refreshed every three days

8. 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.

9. Chongqing jinwowo analyzes and studies the role of blockchain technology in the transaction as follows:
simplify the process and improve efficiency
because blockchain technology is a public ledger established by sharing consensus among participants, forming a consensus on the network state, the information in the blockchain is naturally recognized, unique and traceable by the participants It can not be tampered with information source, so a lot of repeated verification and operation process in the transaction process can be simplified or even eliminated
