『一』 [Blockchain blockchain] is more powerful than Bitcoin

Compiled by Joyce, a new vision of grassroots influence

Topics in the past two years Bitcoin is already well known, but its influence may not be as influential as the online wallet technology [blockchain]. Whether it is from voting to health care, music to energy production, blockchain not only affects existing banks , securities brokers, credit card business volume, it may even change our lifestyles.

Voting application

The ballot boxes and online voting platforms that were used to vote in the past can easily be manipulated and cause fraud, while blockchain authenticates identities for transactions and does not need to be managed or guaranteed by a central agency. . Now a new startup called FollowMyVote is developing a blockchain-based system that can ensure the security, transparency and accuracy of the election process and results.

Power Energy Application

Blockchain technology can be applied to power energy: use the unused solar power from the solar panels on the roof to communicate with the solar panels of neighboring buildings, and use the blockchain to Virtual currency settles electricity costs, and the entire transaction process (whether it is power exchange or fee settlement) does not need to go through the energy supplier. Lo3Energy, a new venture under Siemens, is currently launching a microgrid plan for solar power trading in some communities in Brooklyn, New York (such as Park Slope). The blockchain allows homeowners to set their own pricing without paying commissions to middlemen. Thus the cost of sales can be reduced.

Music Media Application

In the past, the traditional music industry structure included layers of so-called "middlemen", such as publishers, music manufacturers, copyright dealers, music platforms, etc., and finally reached the hands of consumers. At this time, the selling price of music products has been driven up due to the layer upon layer stacking, but the actual reward that reaches the pockets of music creators is extremely limited. Blockchain breaks the traditional music industry structure. A blockchain system called Voise allows musicians to set a price themselves. When users consume these music through the platform, musicians can receive almost 100% of the consumption. amount.

Healthcare Applications

In the past, patients' medical records were often scattered among doctors, clinics, and laboratories, causing inconvenience for people to seek medical treatment across hospitals, make insurance claims, etc. Blockchain health records can be read and updated from multiple repositories, containing detailed records of each visit, and patients can choose who to share the data with. At MIT, researchers are developing a system called MedRec that is expected to be integrated with current medical computer systems. Taipei Medical University Affiliated Hospital also led Taiwan to officially enter the health and medical industry blockchain technology in November 2017.

Humanitarian relief applications

According to United Nations statistics in 2012, from30% of development aid around the world is not applied to aid targets due to corruption. The United Nations is currently developing some blockchain projects to solve this problem. For example, in the 2017 United Nations World Food Program experimental project, Syrian refugees in Jordan received cryptocurrency subsidies. When refugees shop in supermarkets in the camp, their identities will be verified through eye iris scans, and the consumption amount will be deducted from the subsidies. This experimental project can not only reduce the cost of UN affairs, but also reduce the chances of fraud and theft.

『二』What are the specific applications of blockchain + energy?

With its own advantages, blockchain can provide solutions to the three major energy problems: by optimizing the energy process, Blockchain can reduce costs; blockchain can improve energy security from the perspective of network security; use blockchain as a supporting technology to improve supply security, and ultimately achieve sustainable development of energy through energy management and control.

More importantly, blockchain technology can be applied to the following fields and aspects to help solve problems in the field of energy management and control: For example, in the power resources sector, automated blockchain can improve decentralized energy systems and Management and control of microgrids. Adopting local energy markets through localized energy peer-to-peer trading or distributed platforms can significantly increase self-production and self-consumption of energy. Applications and Data Transfer Blockchain can be used for communication, data transfer or storage of smart devices. Smart devices in smart grids include smart meters, advanced sensors, network monitoring equipment, energy management and control systems, smart home energy controllers and building monitoring systems. In addition to providing secure data transmission, smart grid applications can also benefit from data standardization enabled by blockchain technology. There is also electricity bill management. In electricity transactions, when the electricity sales company, power generation, and electricity consumption are not one subject, it is difficult for all parties to trust each other. The trusted blockchain public service platform enables cross-verification, openness and transparency of multi-party information such as power generation and online power, and builds a fair transaction mechanism in the network environment. Immutable records and transparent processes can greatly improve auditing and regulatory compliance.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "Smart Learning Factory 2020- Xueshuo Innovation Workstation" launched by the School Planning and Construction Development Center of the Ministry of Education of China. Approved "Blockchain Technology Professional" pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

『三』A user-centered microgrid green electricity trading blockchain data model is in which journal?

A user-centered microgrid green electricity trading The blockchain data model is available in the journal "Power Communication Technology Research and Application".
Distributed energy, with green new energy as the main body, has become an important part of the energy trading market. In order to improve energy utilization and expand local consumption of distributed energy through multiple channels, distributed energy has obtained the legal qualification to sell electricity nearby. The structure of energy production and consumption is centerless, multi-node shape. Due to the characteristics of centralized management, the existing energy operation model is difficult to be easily applied to distributed energy resources. Blockchain technology has the advantages of traceability, open transactions, and data transparency. Its decentralized characteristics are consistent with the centerless characteristics of distributed energy. Therefore, a distributed energy trading solution based on blockchain is proposed. Analyze existing distributed energy transaction methods and their drawbacks, study the applicability of blockchain technology to distributed energy P2P transactions, and analyze the application of continuous double auction (CDA) and competitive equilibrium price (CEP) , node reputation value, etc., establish a distributed energy settlement mechanism to support P2P transactions of distributed energy, formulate a distributed energy blockchain payment model in line with Chinese policies, and propose a blockchain technology-based system including system architecture and transaction process. Distributed energy trading solutions, compare the performance of traditional power trading systems and blockchain-based distributed energy trading systems, think about how to improve the shortcomings of the current blockchain and look into the future of the energy market, and realize the distribution of traditional power trading markets Extended development of energy trading.

『Wu』 Energy Blockchain Research | Blockchain use cases in the energy industry

If implemented properly, blockchain Technology has the potential to revolutionize every aspect of the energy industry.

As the energy industry becomes increasingly decentralized, blockchain technology is ideally positioned as a major disruptive force. In fact, companies around the world are already developing blockchain applications to create direct connections between energy producers and consumers.

Blockchain is a virtual public ledger that records transactions in a secure and transparent manner without the need for third parties such as banks, public institutions or electricity providers to act as intermediaries. But how exactly can blockchain be used to improve operations in this area? Let’s explore some of the most exciting applications of this promising technology in the energy sector.

Energy Sector

◆Facilitates peer-to-peer energy trading◆

Traditional energy delivery models rely on centralized power plants millions of miles away, which are located Electricity is transported on transmission and distribution lines, commonly known as the "grid". The less discussed “microgrids” are local grids that can connect and disconnect from the traditional grid when necessary. Microgrids use local energy sources such as wind and solar power to power local loads together.

Microgrids enable consumers to both produce and consume energy, giving them the opportunity to become "product consumers." As producers, they are able to sell any surplus energy they may have on a pay-per-use basis to peers connected to the same microgrid. Blockchain technology facilitates this peer-to-peer energy trading by providing microgrid members with a secure and transparent distributed ledger. This provides a highly reliable and cost-effective way to create, verify, record and coordinate peer-to-peer energy transactions in real time.

Energy Sector

◆Let electric vehicles continue to drive◆

According to data from BloombergNEF, global electric vehicle sales exceeded 2 million units in 2018, more than at the beginning of this century There is a significant increase in the number of thousands of vehicles a year. Additionally, Bloomberg expects this number to increase to 10 million by 2025 and 56 million by 2040.

With more and more electric vehicles on the road, private charging stations are likely to become valuable assets, requiring an efficient system to coordinate energy transactions between drivers. Blockchain technology can be used to create a system that can monitor electricity prices, make pricing decisions in specific markets, and enable charging station owners to conduct secure transactions.

Energy Sector

◆Simplify regulatory procedures ◆

Energy companies need to submit a large amount of data to regulatory agencies to prove their compliance with various regulations. Collecting and cleaning all this data using current technology is not only tedious, but also creates serious problems related to incorrect data access. The more data you process, the more people you need to be involved, and the greater the chance of accidental exposure of sensitive company information.

Because blockchain ledgers are both immutable and completely transparent, introducing them into energy companies’ operations will give regulators the greatest confidence that the data they receive is unedited. The introduction of blockchain will also give energy companies unparalleled control over what information is shared with whom, all but eliminating the possibility of sensitive data falling into the wrong hands. To boot, blockchain technology introduces the ability to standardize data collection and transmission formats.

Energy Sector

◆ Expanding energy access ◆

Many communities around the world are not connected to the grid. Energy in these communities often comes from local solar panel projects, many of which do not receive adequate funding.

Crowdfunding can help close this financing gap. The idea here is for individuals or other small investors to pool their resources to purchase enough photovoltaic cells to build the necessary number of solar panels for a given community without electricity. These micro-investors retain partial ownership of the solar panels and earn income, with the community paying a marginal amount each month for the electricity generated by the solar panels.

Introducing blockchain technology into this process will alleviate many of the problems that plague traditional crowdfunding. First, blockchain-based crowdfunding will enable anyone with an internet connection to donate to a campaign, which is simply not the case with traditional crowdfunding platforms. Additionally, just like peer-to-peer energy trading within microgrids, blockchain technology can reduce the overall cost of monthly transactions between solar panel owners and the community powered by the panels. Finally, because blockchain is completely secure and transparent, blockchain greatly reduces the chance of crowdfunding fraud. On the contrary, it is difficult for traditional crowdfunding platforms to eradicate this kind of fraud.

Energy Sector

◆ The bright future of blockchain◆

These use cases show that blockchain applications have the potential to revolutionize our energy consumption, transactions, Regulation and financing methods. Once key stakeholders in the energy industry get involved, blockchain may well become the key to keeping the lights on for millions of people around the world.

Blockchain can help us fight climate change

p>

·Smart contracts run on the blockchain, which can unlock many new ways to deal with climate change and address its impacts.

·Achieving this requires a value intermediary network, which can help the blockchain collect information from real society and interact with it.

Note: Oracles (value intermediaries) provide data to smart contracts and are the bridge between the real world and the blockchain.

Smart contracts allow people to design a globally accepted and fully automated incentive system that can directly reward individuals, companies and governments that participate in sustainable practices. These practices include: regenerative agriculture, carbon offsets, crop insurance, and more. In promoting global green actions, smart contracts have greatly incentivized participants.

Initial obstacles

The development of green smart contracts is hindered, mainly reflected in the inability of the blockchain to interact with information from various regions in the real world, including the environment. In recent years, however, physical companies have finally been able to go into production through oracle mechanisms that integrate global data onto the blockchain.

For example, these oracle mechanisms can now publish agricultural information sets directly to the blockchain, and smart contract developers can eventually develop a series of small predictions about food yields, soil quality, climate reporting, carbon offsets, and more. program. As more and more environmental data sets, such as weather patterns or Internet of Things (IoT) sensor readings, are fed into the blockchain, developers are beginning to develop a wide range of environmentally friendly smart contract applications.

The following are three related examples

1

Regenerative agriculture

Smart contracts allow ordinary people to participate in the fight against climate change One of the most important ways, it promotes the development of regenerative agriculture and makes regenerative agriculture possible.

Smart contracts can interact with real-world information to autonomously reward those who develop important land.

For example, the Green World Campaign is working with Cornell University to build a smart contract that can automatically reward those who pass satellite information through People who have successfully regenerated land by increasing vegetation cover, improving soil, etc.

Value intermediaries can also extract data from satellite images and trigger smart contracts built on the blockchain to ensure that people receive rewards fairly and transparently.

2

Changing consumer awareness

Smart contracts can supportEnvironmentally conscious individuals and organizations. For example, if a person successfully triggers a reforestation smart contract, they can be paid in the form of carbon credits that can be sold to charities, crowdfunding, or even companies that have a positive impact on the environment.

Smart contracts can also provide environmentally conscious consumers with more choices in energy consumption.

For example, decentralized energy grids like the Brooklyn Microgrid Projectare could use smart contracts and blockchain as a coordination mechanism to allow consumers and their neighbors to take advantage of solar energy Generate electricity and generate transactions. Buying and selling solar credits among neighbors can reduce energy transportation costs and greenhouse gas emissions.

While many consumers are already changing their consumption habits, broader social behavioral shifts may require a combination of monetary incentives and sustainable choices among consumers. By using smart contracts connected to real-world data, different spending habits trigger different reward and punishment mechanisms. This will promote changes in consumer behavior.

Hedging risks by insuring crops

Climate change is altering weather patterns around the world. The vast majority of farmers around the world are uninsured, leaving their crops extremely vulnerable to weather conditions such as heavy rain, drought, and strong winds.

Adverse weather conditions can cause financial losses to farmers, devastating their families and leaving farmland damaged and abandoned.

Fortunately, smart contracts can detect changing climates through value intermediaries and propose solutions.

Using smart contracts, farmers can insure their land, stipulating predefined conditions for the contract to be effective (such as a certain amount of rainfall); they can then detect weather patterns through a value intermediary.

If the value intermediary detects that the conditions have been met, the farmer automatically gets a sum of money.

Smart contracts communicate climate information through value intermediaries, allowing farmers to protect their property with just a smartphone.

Outlook

The combination of blockchain and value intermediary opens up a new era of smart contracts, which can create a new incentive model for sustainable human energy consumption. . As discussions about climate change continue to escalate, it’s important to understand that the impact of this industry on the environment will go far beyond the consensus mechanisms of any one project.
