蓬勃区块链,区块链poa

蓬勃发展的区块链技术提供了一种新的、可靠的记录、存储和交换数据的方式，并且能够支持大规模的分布式应用。而POA（Proof of Authority）拓展，则为区块链技术提供了更多的可能性。以下是POA拓展的三个关键词：

共识机制是区块链系统中最重要的组成部分，它的主要功能是确保区块链网络中的所有节点能够达成一致，以确保网络的安全性和可靠性。POA拓展的共识机制是基于授权的共识机制，它是一种基于授权的共识机制，允许受信任的节点（称为验证者）授权确认交易，从而实现区块链网络的安全性和可靠性。

智能合约是一种可以自动执行和管理的计算机程序，它可以帮助用户实现自动化的交易，而无需人工参与。POA拓展的智能合约可以更有效地实现自动化的交易，更加安全、可靠，并且可以提高交易的效率。

去中心化是区块链技术的一个重要特征，它指的是没有中央机构，也没有单一实体可以控制或管理区块链网络。POA拓展的去中心化特性可以更好地保护用户的隐私，使用户能够安全地参与区块链网络中的交易，而不必担心被中央机构或其他实体控制或监督。

总之，POA拓展为区块链技术提供了一种更安全、可靠的方式，支持共识机制、智能合约和去中心化，从而使区块链技术得以更好地发挥其作用。

Ⅰ What epic vulnerabilities did 360 discover in the blockchain?

According to news on May 29, recently, the Vulcan team of 360 Company discovered the blockchain platform A series of high-risk security vulnerabilities in EOS. It has been verified that some of these vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks.

Blockchain network security risks require urgent attention

EOS is a new blockchain platform called "Blockchain 3.0". The currency market value is as high as 69 billion yuan, ranking fifth in the world in market value.

In the blockchain network and digital currency system, there are many attack surfaces in nodes, wallets, mining pools, exchanges, smart contracts, etc. The 360 ​​security team has previously discovered and exposed multiple attacks against Serious security vulnerabilities in digital currency nodes, wallets, mining pools, and smart contracts.

The series of new security vulnerabilities discovered by the 360 ​​Security Team in the smart contract virtual machine of the EOS platform are a series of unprecedented security risks. No security researchers have discovered such problems before. This type of security issue not only affects EOS, but may also affect other types of blockchain platforms and virtual currency applications.

360 expressed the hope that through the discovery and disclosure of this vulnerability, the blockchain industry and security peers will pay more attention and attention to the security of such issues, and jointly enhance the security of the blockchain network. Safety.

II What is the relationship between Bitcoin and blockchain?

What is the relationship between Bitcoin and blockchain?

Some people say that Bitcoin and blockchain are in a chicken-and-egg relationship.

Some people also say that Bitcoin and blockchain have a father-son relationship.

Some people say that Bitcoin is a killer application of blockchain.

In this family, everyone knows the property they own, but they cannot occupy it privately.

Everyone has his own private key, which can be viewed and belongs only to his own property. Others cannot take it away, and you cannot tamper with it.

If you want to have more property, you will only be rewarded by the family if you contribute to the family, and your property will increase.

In this family, there is absolute fairness and freedom, without any infighting or bullying. It is a beautiful home that everyone longs for!

The first assignment of Class III "Golden Horse takes you to invest in the blockchain": Look up at the stars and keep your feet on the ground (2)

This article follows the previous article "Look up at the stars, Down to Earth (1)", continue to record and summarize the learning and insights in the blockchain field over the past two months, and review the investment concepts involved in some articles in "The Road to Wealth Freedom".

From the previous article, you can feel that I am not professional in blockchainKnowledge, or related technology has been explained too much. There are two reasons. (1) I am also a blockchain novice who has just been involved in the industry for less than 3 months. I am not engaged in the financial or IT industry, and I have little knowledge of technology. Although I have accumulated a lot of knowledge during this period, But I don’t dare to share it rashly here. It needs to be deeply settled. (2) For these two articles, what I want to output, express, and convey is the broader aspect, that is, the investment philosophy about investing in blockchain or other subject matter (including individuals), and my feelings about blockchain. Of course, people who are interested will take the initiative to look up relevant information instead of listening to my nonsense. For people who are not interested in blockchain, even if I write boring content, it will be like listening to half a book.

Back to the topic, let’s continue the review.

Let’s review this time. In the article “What does it mean to put it all in”, Mr. Xiaolai put forward the following point of view.

1. The pursuit of 100% security is a shackle that most people carry throughout their lives;

2. One of the most important attributes of the future is that it is partially unknowable; investment, It is a future-oriented judgment and decision-making;

3. Giving up a little bit of security, or not pursuing 100% security, is essentially just a calm acceptance of reality. However, for most people, the most difficult thing to accept in this life is reality;

4. In order to avoid the biggest risk (no chance again), as an investor, you must remember and not violate The iron rule is: never bet everything;

5. How to improve your chances of winning as much as possible, the simplest answer is to improve your thinking quality;

6. Real life There is rarely a 100% chance of making a profit, or even if there is, it's not your turn, so wise people never "bet everything."

Quoted from "The Road to Financial Freedom"

Combined with myself in May, as a "risk blind", I did do a stupid thing - —I’m ALL IN~! Let’s talk about my funny experience before I had any study.

I spent 5,000 yuan to buy part of BTS because I had just started to get in touch with it. I stared at the amount in my account every day, and my heart was surging, but in order not to affect my next two steps. After taking the professional construction engineer exam, I sold decisively when I earned 50%. I was overjoyed. It turns out that making money can be so easy. Be ruthless about short positions and withdraw your money. After taking the test, I found that the price was still rising. I thought to myself, "Don't be in a hurry, wait a minute," I thought, and I would wait and see again. I observed for 1 day, 2 days, and 3 days. . . It wasn’t until 7 days later that I suddenly realized that the currency industry was in a bull market and I could make money no matter what currency I bought. In these 7 days, IDidn’t buy anything, NND! It's like missing out on hundreds of millions. Therefore, I decided to buy some for each coin and not put all the eggs in one basket. ALL IN, who thought he was smart, took out part of the money from current financial management and transferred all the money from Alipay, WeChat, and salary cards, hoping to make a lot of money. However, I found that after buying it, the situation changed suddenly. On May 27, all currencies plummeted, and my capital account lost 50%. I was cut in half. It was so exciting, so exciting. The following picture is really appropriate to express my mood at that time.

Continue to review, "What is the simplest safe investment strategy"

1. The core methodology of investment success is so simple that it is ridiculously simple: buy low, sell high ; But the simplest things are often the hardest to do...

2. "Using the doctrine" has long been proven to be "defeated" in the investment field, and the "reaching out party" is doomed They are prey in the investment world.

3. As a qualified investor, you must develop the habit of relying on yourself as much as possible from the beginning. Every mindless dependence on others is a further abandonment of the training of one's own abilities. If you are someone who can't do your own research, can't think by yourself, and can't make your own choices, you shouldn't enter the investment field from the beginning.

4. The most effective means of safe investment strategy - fixed investment strategy (regularly purchase a certain (or several) growth stocks in equal amounts.) This is also the best hedging tool, and the fixed investment strategy The advantage is that except for regular fixed quota purchases, you don’t have to do anything, you don’t have to study K-line analysis techniques, you don’t have to watch his stock price every day, you don’t have to care about his news, you don’t have to inquire about his various inside stories...even, If you can sentence your funds to more than 7 years, there is no need to even read the annual report. Focus on what's important.

5. In the field of investment, homework is done for yourself, and after you finish it, you have to use your own funds to practice your homework, and then it will take five, ten, or even A longer time to wait for the results of that homework...

Quoted from "The Road to Wealth and Freedom"

The above dry information is what I am practicing now. OK. I would like to make two advertisements here (in fact, they were also mentioned in the previous article). If you are interested in blockchain, two small secret circles will be given to you, which are priceless!

Wang Yunpeng's "Personal Rise Investment Practical Book"

Peng Ge's Small Secret Circle, currently priced at 700 yuan/year, is full of excitement and has a more forward-looking perspective Sex, the WeChat group in which I am a member, is full of big names, many of whom are blockchain founders, practitioners, experienced drivers, experts, and teachers, and are in the expensive circle.~Finally, I believe you will not miss a good investment opportunity.

Jinma's "Jinma takes you to invest in the blockchain"

Jinma's small circle is currently 388 yuan/year. Compared with Yunpeng brother, the style is more stable. , mainly for blockchain novices, teaching various introductory courses step by step. After entering the industry, I believe you can understand blockchain, Bitcoin, various ICOs, etc. even with zero basic knowledge.

Final review, "The Most Basic Skill in the Investment World—Trend Judgment"

1. Everything in this world is actually investment, and growth is about using Invest your own attention in yourself. Marriage is about both parties jointly investing their various resources to create a better family. Work is an investment, starting a business is still an investment, everything is an investment.

2. In fact, the real trend often needs multiple cycles (at least 2) to truly unfold. Paying attention to cycles and the real trends emerging behind multiple cycles will give you a new and more reliable world and perspective.

3. Even in order not to become "leeks", we should also learn the knowledge of investment and financial management. This may be the most important "knowledge realization" for us.

4. There must be various ways to make money other than investment to ensure that you can definitely give your invested amount a "life sentence" (at least a longer "term imprisonment").

3. The most important use of understanding cycles is that it can help you see the future. At least seeing a small part of it, even a little bit, is much better than not seeing it at all. A lot, and seeing just a little bit more over the years, in the end, will form a huge cognitive difference, and in the end, there will be a huge gap between people.

Quoted from "The Road to Wealth Freedom"

Based on myself, there was no idea about the investment more than a month ago, except for participating in part of the BTC and almost all of the ETH. In addition to the ICOs of SNT, EOS, and PRESSONE, other asset allocations have become like this:

I was also drunk when I saw it. During the waiting period, I still need to continue learning, researching, and grasping trends. At an appropriate moment, I will change and adjust my allocation in exchange for assets with a high growth rate.

Strengthen your learning ability, learn whatever you need, and output whatever you learn. Teaching is the best way to learn. Become an expert in this field, and then think, make decisions, and act like an expert. Now I am a bricklayer (a small worker) and strive to become an expert.

Finally, I continue to quote a sentence from the author of the book on personal development and investment practice:

Investing in the blockchain,

is never the most important thing!

The most important thing is,

Invest in yourself!

"Guangming Online Review" digital empowerment, work together to build a community of shared future in cyberspace

Author: Xie Weifeng

It is the beautiful scenery of Jiangnan, and the autumn season will meet again Jun. The 2022 World Internet Conference Wuzhen Summit will be held in Wuzhen, Zhejiang from November 9th to 11th. The summit will be themed "Co-building a cyber world and creating a digital future - Working together to build a community with a shared future in cyberspace" and will be held in a combination of "offline + online". There will be attendees from more than 120 countries and regions. governments, international organizations, and industry bodiesNearly 2,000 representatives from Chinese and foreign Internet companies and university think tanks jointly conducted exchanges around the theme of the summit and provided wisdom and advice for the construction of a community with a shared future in cyberspace.

The Internet has turned the world into a "global village", and digital civilization has increasingly become the macro background for the advancement of the times. At the same time, the question of the times, what kind of cyberspace should be established and what kind of international Internet governance system should be constructed, urgently needs to be answered. It was also at the World Internet Conference, a grand platform with global attention, that China took the lead in proposing the "four principles" that should be adhered to in promoting the reform of the global Internet governance system and the "five-point proposition" to build a community with a shared future in cyberspace, which triggered the international community Strong resonance. Although cyberspace is virtual, the scenes of interconnectedness and interdependence between countries are real. If human beings coexist in the same cyber dimension, they must eliminate confrontation with cooperation and replace zero-sum with win-win. This is exactly why China's plan to jointly build a community with a shared future in cyberspace comes from.

Time is the best witness. From 2014 to 2022, the World Internet Conference is in its ninth year. If you follow its development, you will find that the key words in previous themes always resonate with the times: from interconnection to innovation-driven, from intelligent interconnection To create a future together... The advancement of views and concepts with the times has benefited from the rise of digitalization, and the original mission of working together to build a community of shared future in cyberspace has set the "where to go" for us. The forward coordinate of the world - when moving towards a new era of digital civilization has become a general trend, then working together to create the future through digital empowerment is a solid promotion and active construction of a community with a shared future in cyberspace.

The word "digital" is also included in the theme of the 2022 World Internet Conference. If network development is a "two-way rush" with China, then digitalization has the most realistic foothold. According to estimates by research institutions, as of 2021, the scale of China's digital economy will reach 45.5 trillion yuan, accounting for 39.8% of GDP. The digital economy has become one of the main engines driving economic growth. The scale of the digital economy has ranked second in the world for many years in a row. Behind the data, it is the hot scene that the development of China's digital economy has arrived, its momentum is established, and its prosperity can be expected. "One flower blooming alone is not spring, but when a hundred flowers bloom, spring fills the garden." China does not build "walls" but builds "bridges" to share its digital achievements with the world: deepening international cooperation in the digital economy, jointly safeguarding cyberspace security, and actively Participate in the reform and construction of the global Internet governance system, promote the inclusive development of the Internet... and work together to build a community with a shared future in cyberspace through digital empowerment. The simple concept of a country has become clear.

Stimulating the vitality of the digital economy, enhancing the effectiveness of digital government, optimizing the digital social environment, building a digital cooperation pattern, and strengthening digital security barriers... every step forward in digitalization, every breakthrough, Every leap is a "reservation" for working together to build a community with a shared future in cyberspace."Potential", and the key to achieving the vision is to find the path of energy conversion in "empowerment" and "cooperation". This Wuzhen Summit will focus on cooperation and development, technology and industry, humanities and society, governance and security There are four major sections and 20 sub-forums. During the period, the world's leading Internet scientific and technological achievements release event, the "Working Together to Build a Community with a Shared Future in Cyberspace" practical case release and display event, the "Light of the Internet" Expo and the "Straight to Wuzhen" global event will also be held. Internet competitions and other important activities, and continue to release the outcome documents "China Internet Development Report 2022" and the "World Internet Development Report 2022" blue book. Let's build an online world and create a digital future together. When the world Internet is about to enter "Wuzhen time" again, we How can we not be full of expectations for this! (Xie Weifeng)

Join hands to build a community with a shared future in cyberspace

July 12, 2022 , the World Internet Conference international organization was established, which marked the transformation of the World Internet Conference into an annual meeting of an international organization. As the first annual meeting after the establishment of an international organization, this summit will actively build a high-end global Internet dialogue platform with international parties.

Openness and cooperation are important conditions for building a community with a shared future in cyberspace. Li Hongwei, deputy director of the Institute of Cyberspace Security of the University of Electronic Science and Technology of China, said that in recent years, the data security situation has become increasingly severe, and the influence of various security incidents has escalated, which urgently needs Secure data collection, transmission, storage and use mechanisms overcome the limitations and defects of traditional solutions and ensure the safety of important infrastructure and people's lives and property in countries around the world. "Countries around the world should join hands to ensure global data security and create a digital future , and build a global cyberspace community with a shared future. ”

“In the information age, no country or force can survive alone.A community with a shared future that shares benefits and responsibilities. "Li Yan, executive director of the Institute of Science and Technology and Cyber ​​Security of the China Institutes of Contemporary International Relations, said that under the new situation, ensuring the stability and development of cyberspace has become a major and closely related proposition for the international community, and all parties are working hard for it.< /p>

With the theme of "building a community with a shared future in cyberspace", China has actively built the international platform "World Internet Conference" and is committed to building consensus, promoting exchanges and promoting cooperation. This is not only a response to the general concerns of the international community, but also China’s contribution to the future development of cyberspace.

“The international community is increasingly becoming a community of destiny in which we are among you and you are among us. It is the common responsibility of the international community to develop, use and govern the Internet well so that it can better benefit mankind. "On the eve of the Wuzhen Summit of the World Internet Conference, the State Council Information Office released the white paper "Working Together to Build a Community with a Shared Future in Cyberspace", which explains China's proposition of building a closer community with a shared future in cyberspace focusing on cyberspace development, governance, security, cooperation and other aspects. .

Cao Shumin, deputy director of the Cyberspace Administration of China, said that China will adhere to the concept of building a community with a shared future in cyberspace as a guide, work with the international community to strengthen unity and cooperation, and promote the construction of a more fair, reasonable, open, inclusive, and secure cyberspace. A stable and vibrant cyberspace will allow the Internet to better benefit people all over the world.

In Wuzhen at night, the lights all over the river network flicker, like an "interconnected" information network. It should be a year Once again, this "Internet town" has become lively again. Let's build an online world and create a digital future together. In the next few days, the digital power gathered and unleashed by the World Internet Conference will rapidly radiate around the world from Wuzhen.

VI Which notary office in Shanghai is the fastest

The press conference on the road to notarization through Science and Technology Huitong. Photo by The Paper reporter Deng Lingwei
In response to the Ministry of Justice’s “Digital Rule of Law, Smart Justice” message In order to jointly promote the innovative development of notary business and improve the quality of notary services, on May 9, Shanghai Zhangjiang Notary Office, Shanghai Xuhui Notary Office, Suzhou Notary Office of Suzhou City, Jiangsu Province, and Hangzhou Internet Notarization Office of Hangzhou City, Zhejiang Province Representatives from six notary offices, including the Tianyi Notary Office in Ningbo City, Zhejiang Province, and the Jianghuai Notary Office in Lu'an City, Anhui Province, gathered in Shanghai to hold a press conference on the "Road to Notarization through Science and Technology" to strengthen the construction of a cross-regional public legal service system.
“Actually, this is just the beginning. There will be more and more scenarios that can be developed in the future, such as administrative agency law enforcement. Originally, law enforcement recorders were used to record the law enforcement process and save it on their own. If there is a dispute over law enforcement in the future, That can only prove your innocence, but it will be less credible. Now with the use of blockchain technology, customized law enforcement recorders are used to record videos, and information including real-time audio and video fingerprints is instantly encrypted and transmitted and solidified on the chain. Administrative law enforcement units can apply for notarization online, and the notary retrieves and stores it in Audio and video of law enforcement process on cloud platform, using encryptionThe algorithm performs calculations, compares the obtained data with the data previously obtained on the blockchain, and issues an evidence preservation notarization if the data is consistent. This is a technical guarantee. "Wang Xiaojun, director of the Suzhou Notary Office in Suzhou City, Jiangsu Province, told The Paper.
Wang Xiaojun said that the combination of "blockchain + notarization" applications will be applicable to administrative law enforcement fields involving personal freedom, life and health, major property rights and interests, etc. , record the entire law enforcement process, and realize the real-time solidified transmission of audio and video, fingerprints, device logos, timestamps, locations, battery power and other information. In the expansion of innovative notary services, the transmission information is fully stored and provided for necessary information verification Convenience.
As an integral part of the smart judicial system, the informatization construction of the notary industry is keeping up with the times.

Ⅶ Is blockchain technology expected to lead mankind into the era of machine trust?

Recently, the concept of blockchain has made a comeback. Since February, the U.S. House of Representatives has held two blockchain hearings in succession, elevating blockchain to a "revolutionary technology" and discussing its future applications and impact on finance and business. and government influence. At the same time, Russian President Vladimir Putin also stated that Russia will focus on developing blockchain technology to strengthen Russia’s voice in international competition in the field of cutting-edge technology. In China, more and more industries are beginning to pay attention to regional In the field of blockchain technology, this concept has also become one of the hot topics discussed by representatives during this year's "Two Sessions".

In today's turbulent time of technological development, blockchain There are still many places for us to explore the new technology of blockchain. Especially in high-tech fields where others have formulated the "rules", we should take a long-term view, continue to innovate, digest and absorb the essence of blockchain technology, and strive to form an independent The core competitiveness of intellectual property rights. At the same time, faced with various temptations, we need to be cautious at all times, see risks, avoid losses, and never let economic interests obscure the essence and deep value of the blockchain. Understanding.

Ⅷ Why did Tencent respond to apply for blockchain trademarks such as Bocoin

The official website of the Trademark Office of the State Administration for Industry and Commerce shows that Tencent Technology (Shenzhen) Co., Ltd. applied for infcoin, There are many trademarks such as Bodong Planet, Bodong Star, Bocoin, Qbanking, LinkBanking, etc.

Tencent Blockchain Business Structure Tencent Blockchain pays more attention to the implementation of scenarios and has already Exploration has been carried out in the fields of supply chain finance, games, legal certification, digital assets, public welfare tracing, logistics, taxation and other fields. In March this year, Tencent announced that it was cooperating with the China Federation of Logistics and Purchasing to develop a blockchain supply chain alliance chain and cloud Single platform. Based on the cloud bill platform, electronic waybills will replace paper waybills, and electronic signatures will replace manual paper signatures. Blockchain technology will be used to make them distributed, encrypted, and non-tamperable to ensure the authenticity and security of waybill data. , to achieve "credibility, security, efficiency improvement, and cost reduction." In May this year, Tencent and the Shenzhen Municipal State Taxation Bureau jointly established the "Smart Tax" Innovation Laboratory.The two parties are jointly promoting China's first blockchain-based digital invoice solution and exploring a new invoice ecology. They hope that every invoice can be checked, verifiable, credible and traceable, and use blockchain technology to The entire process of invoice circulation is managed, making the circulation of invoice data in all scenarios a reality.

Ⅸ Blockchain drives the future: Can society really be programmed

"Three o'clock" has been very popular recently, but it is more popular than What is even more popular is the blockchain.

Since the "94 Incident", policies have become increasingly tight for the currency circle. In contrast, the "chain circle", which had rarely spoken out before, has become popular. Regardless of the media or the market, various voices discussing "blockchain" are emerging one after another in social circles large and small. Finally, during the Spring Festival this year, the popularity of "Sleepless at Three O'Clock Blockchain" brought this wave to its peak.

Finally, I would like to end with a quote from Zeng Ming (Chairman of the Academic Committee of Alibaba Group and Dean of Education of Hupan University), so that everyone can experience Teacher Zeng’s surging vision for the future:

p>

Today, what we are doing is to write trust consensus into the program before an economic ecology is born. What a ground-breaking thing this is! We are designing our own destiny! It's almost like we have a CRISP tool trying to encode genes. Just like the fundamental challenges that artificial intelligence encounters in cracking the human brain, the challenges of blockchain in designing the economic system that has evolved together with human society will also be fundamental and revolutionary. Because it directly faces human nature. Only by understanding Token at this level can we have enough awe and a true sense of mission for the historical opportunities and challenges we face.

X What is the relationship between blockchain and Bitcoin

Blockchain technology is the underlying technology of Bitcoin and the core and infrastructure of Bitcoin. Bitcoin has been operating without any centralized organization operation and management. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(10) Extended reading on The Paper Blockchain:

Disadvantages of applying blockchain technology to digital currency:

1 It is "decentralized" and has no circulation management organization. Blockchain technology is essentially a distributed database system, the logical structure is a one-way linked list, and the design model is based on P2P network, which determines that virtual currencies based on blockchain technology do not have a unified central management and control system.

Second, quantity supply is difficult to effectively control. The issuance amount of virtual currency based on blockchain technology is fixed. According to the Fisher equation, the total transaction volume of the whole society at a certain price level in a certain period has a certain proportional relationship with the required nominal currency amount, and a constant currency amount is obviously cannot meet the ever-increasing social commodity price total.amount requirements.

Third, the “mining mechanism” is difficult to create recognized value. Bitcoin itself has no value and is not supported by national credit. Some people believe that "injecting value into virtual currency by continuously consuming computing power and energy", but consuming trillions of calculations to find a hash value that meets the requirements is obviously not the most efficient option.

Fourthly, producers and early holders can easily obtain high "seigniorage". Any virtual currency based on blockchain technology is held by a small number of people in the initial stage of its development. Take Bitcoin as an example. Initially, Bitcoin was just a product of a few people’s games. The first Bitcoin purchase that occurred in May 2010 was a $25 pizza purchased with 10,000 BTC. The first Bitcoin transaction was completed in July of the same year. It is $0.04/BTC.
