1. Improving network security
blockchain is a decentralized and distributed electronic classified accounting method based on the model of providing absolute security and trust. Using encryption technology, transactions are recorded chronologically and publicly, and each block has a timestamp and a link to the previous block. Importantly, these digital "blocks" can only be updated through the consensus of all participants, and data interception, modification and deletion are almost impossible.
2. The analysis of Chongqing jinwowo is as follows:
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
this field is considered as a promising application direction of blockchain.
3. More often, blockchain technology will be attached to the B / s and C / S structure of the Internet to achieve functional expansion, but it is still a supplement to the existing Internet technology. At present, most of the application scenarios of blockchain can be realized with B / s and C / S structure, with higher efficiency and more mature technology
whether from the perspective of information transmission efficiency and resource consumption, or from the perspective of nervous system evolution, blockchain cannot become the mainstream architecture of the Internet, let alone the subversive and revolutionary of the future Internet.
4. Blockchain technology can help us improve the security of encryption, authentication and other protection mechanisms, which is absolutely good news for the Internet of things security and DDoS Defense Community
blockchain has the potential to become an important solution for safe communities, as well as for the financial, energy and manufacturing instries. At present, verifying bitcoin transaction is one of its main uses, but this technology can also be extended to smart grid system, content delivery network and other application scenarios
how to apply blockchain to network security
whether it's protecting data integrity or using digital identification technology to prevent Internet of things devices from DDoS attacks, blockchain technology can play a key role, at least now it has shown this ability
Internet of things security and DDoS Defense Community
a blockchain startup claims that its decentralized "billing" system can help users resist DDoS attacks with traffic over 100gbps. Interestingly, the company said that this decentralized system allows users to rent their own extra bandwidth and submit their bandwidth access rights to the distributed nodes of the blockchain. When a website suffers from DDoS attacks, the website can use the leased bandwidth to mitigate DDoS attacks
improve confidentiality and data integrity
although the original design of blockchain did not consider the specific access control, now some blockchain technology implementation has solved the problems of data confidentiality and access control. In this era, any data may be tampered, which is obviously a serious problem, but the complete data encryption maliciously guarantees that the data will not be accessed or tampered by others through man in the middle attack in the transmission process
the whole IOT instry needs data integrity protection. For example, IBM's Watson IOT platform allows users to manage IOT data in a private blockchain network, which has been integrated into their big blue cloud service. In addition, Ericsson's blockchain data integrity service provides comprehensive audit, compatible and reliable data services to allow developers to use predix PAAS platform for technical implementation
one of the best applications is the transformation of our public sector and the creation of citizen centered infrastructure. This will enable the public to have their own identity and every transaction can be verified. We can use smart contracts and signed assertions to formulate elements of public services, such as benefits, etc
Internet of things & amp; Smart devices
now the attention of the whole IT community has begun to shift to the Internet of things & amp; Smart devices are on the rise, and security is absolutely one of the primary considerations. Although the Internet of things can improve our work and proction efficiency, it also means that we need to face more security risks. As a result, many companies seek to apply blockchain to protect IOT and instrial IOT (iiot) devices because blockchain technology can enhance authentication, improve data traceability and mobility, and assist record management
according to Alexey malanov, an anti-virus expert at Kaspersky laboratory, blockchain technology helps to track hacker attacks, adding:
"network intruders usually clear the permission log to hide traces of unauthorized access to devices. But if the logs are distributed in multiple devices (for example, through blockchain Technology), the risk can be reced as much as possible. "
German Klimenko, chairman of the digital economy development fund, said: "at present, the Ministry of defense is vigorously promoting it development and research, which is a good thing for the instry."
NATO and the Pentagon are also studying the "defensive" Application of blockchain. This technology is actively used to protect the system from network attacks. NATO will use blockchains to protect financial information, supply and logistics chains, while the Pentagon is developing a data transmission system to prevent hackers
in general, blockchain technology is not omnipotent, at least not yet. Whether from the perspective of technical integrity or system implementation, the current blockchain technology can not guarantee the security of the device 100%. Note: the above content comes from the Internet
5. The analysis results of jinwowo network are as follows:
in terms of data privacy protection, jinwowo blockchain technology will be greatly different from traditional big data
it will make use of the unique encryption method of blockchain to protect the privacy of platform users, and put an end to the "privacy leakage" event of some Internet famous enterprises
let users experience good service and feel more at ease with their personal information.
6. The blockchain system must be applied to the blockchain technology, but now some of the digital currencies connected to the blockchain are also known as the blockchain system, which needs to be studied; It has the characteristics of blockchain technology, that is, decentralization, irreversibility, distributed storage, transparency and openness; Shengshi Huacai is very professional in blockchain, which is worth recommending
7. Adding blockchain support to the device before it leaves the factory can make direct monetary settlement among different operators in the whole network.
8. Bitbox has developed a mobile phone system based on blockchain and Internet of things technology. Using blockchain technology, it can provide direct transaction of trust free intermediary, and using blockchain technology to build a distributed network of intelligent devices, which verifies the feasibility of decentralized Internet of things architecture.
9. Blockchain technology can solve the problems from the technical level.
10. Before, I listened to a song "true hero", which benefited me a lot. There is a passage of lyrics, grasp every minute of life, go all out to our hearts dream, without wind and rain, how to see the rainbow, no one will casually succeed. This sentence made me understand that no matter what I want to do, I should cherish every minute and every second of my life and do what we want to do most in our hearts; And in the career, learning will encounter some difficulties, don't lose heart, because no matter who can't succeed without difficulties. There is a saying that I think is well said, don't do what we like, but like what we do. Don't we have true heroes around us? The cleaners in the building area are not too smelly or dirty. They sacrifice themselves to provide a beautiful living environment for everyone; The traffic police uncle who stands in the middle of the road and commands the vehicles every day dare not relax for the safety of the people; The uncles who worked in the construction site every day, they exchanged their sweat for the tall buildings, built our beautiful teaching building, and built our quiet and warm home for us. There are many "true heroes" around us, but we have never found them. Someone once said, "the world is not lack of beauty, but lack of people to find it." In the world, not only the people like Dong Cunrui who bombed the blockhouse are heroes, not only the people like Huang Jiguang who blocked the muzzle with his chest are heroes, but also the martyrs are heroes, because as long as they serve our human society, they are heroes. I think so. In today's society, there are a lot of "true heroes". However, for those who wish to be true heroes, I hope that when I grow up, I will be a "true hero" who dedicates to the people and has no regrets! All in all, all in all. As long as I go all out to do what we want to do, and succeed, then we can become a respected "true hero"“ Seize every minute of life, go all out to dream in our hearts, how can we see a rainbow without going through the wind and rain, no one can casually succeed... "This is the famous singer Zhou Huajian's" true hero ". When I hear this song, I will be enthusiastic and feel boundless emotion in my heart, and I will sing along with that song, because this song praises the people, There are countless "true heroes" among the masses. In life, there are true heroes; In learning, there are true heroes; In career, there are also true heroes... In life, tenacious people are true heroes. Once there was a disabled child who was lame. Would he give up his life? He won't, he will never! If he wants to live on, he has to rely on his own efforts to succeed. Finally, with his own efforts, he overcame many difficulties in his life and study. He was finally admitted to the University, and achieved excellent results in his study. He was able to get a scholarship every year, which reced the burden on his family. When he was worried about looking for a job, the school saw that there was such a good talent, and he was also a disabled person. Everyone was deeply moved by his spirit of being disabled, loving life, and living tenaciously. So they left the disabled person, and he had a stage to show himself, and he could also bear the life of his family. Is he a true hero? He is. He works hard and creates. He lives tenaciously and creates miracles again and again. He is a strong man in life. Under the threat of illness, he not only never flinches, but also works harder. Finally, he conquers the illness and the cruel fate, and becomes a true hero who challenges the fate like Hawking. He deserves to be a true hero. In learning, the striver is a true hero. In the program "moving China", I saw a big brother who was still struggling under the condition of very poor family and finally went to university. He didn't just care about himself. While he was studying hard in school, he worked hard to make money. He wanted to help his sister study. He continued to struggle, He didn't want to bow down in front of others. He took his sister to school and depended on him. He took care of his sister himself and let the family worry less. In the University, his performance is also very good, deeply appreciated by teachers and classmates. But he is not satisfied with his present achievements. He has a higher and more ambitious ideal - he wants to study as a postgraate and doctor in the best school in China. This big brother is not only a strong man in life, but also an outstanding one in study. Is he a true hero? Yes, he is. He struggles, he wants to make his family life better, he wants to let his sister read a book and go to university like him, he struggles in his study to make his family live a happy life, his quality and persistence in knowledge are not precious wealth? Isn't he worth learning from? Shouldn't he be a true hero? Let's sing this song "true hero" again, the true hero in the song! Whenever this old song starts, I feel a lot of emotion“ In my heart, I once had a dream to forget all the pain with singing: everyone has his own sweet dream. When we have pain, we can use moving singing to appease our emotions“ The brilliant starry sky, who is the real hero, ordinary people give me the most moved ": grasp every minute of life, go all out to our hearts of dreams, do not experience wind and rain, how to see the rainbow, no one can casually succeed..." a sweet song in my ear for a long time! This song is true hero. Whenever this old song starts, I feel a lot of emotion“ In my heart, I once had a dream to forget all the pain with singing: everyone has his own sweet dream. When we have pain, we can use moving singing to appease our emotions“ Brilliant starry sky, who is the real hero, ordinary people give me the most moved ": in the starry sky bright night, I do not know who is a hero, a winner, although ordinary, simple, but gave me favor, let me move“ No more hatred and no more pain, I hope there is love everywhere in the world: May there be no hatred and no sorrow in the world, and the shadow of love and the trace of care can be seen everywhere in the vast territory“ Wish you a different life from now on“ Grasp every minute of life: every inch of time is precious. Although life is short, time is precious. We should make good use of precious time in our short life“ Go all out for the dream in our heart: since there is a sweet dream, we should try our best to realize it“ No one can casually succeed in seeing a rainbow without experiencing wind and rain ": only after experiencing countless storms, lightning and thunder can we see a colorful rainbow. If you want to succeed, if you want to win, you must experience setbacks and overcome many difficulties. No one can succeed casually and coincidentally“ When you are moved, you should hold it well and hug your beloved friends“ Let sincere words and happy tears flow in the bottom of my heart: as a friend, we should share happiness and difficulties. If you have sincere words, you should tell them to your friends. If you have happy tears, you should flow in your heart with your friends... "If you don't experience wind and rain, how can you see a rainbow? No one can casually succeed!" Yes, only those who are self-reliance, determined to become talents, have sweet dreams and great, noble thoughts and sentiments, are worthy of experiencing the wind and rain, to see the bright and dazzling rainbow, to be a strong person in life, to be a "man of virtue", to live a happy and happy life... Students, in fact, success is not far away, it is far away and near! As long as there are "three hearts", you will certainly be able to go to the smooth road of success! What are the "three hearts"? They are: enough patience, unswerving determination (also can be said to be perseverance) and undaunted confidence. The melodies of leisurely floating over the noisy city are like a clear spring, moistening every one who has heard enough; Sentimental & quot; My heart. So, in that sty corner for a long time, there is a familiar feeling. At the same time, also remember the name of the song, true hero. There are kitsch elements in the songs of Hong Kong and Taiwan - resentful and crazy. In short, there are not many that can be recognized by the people in mainland China. However, this song is like a pure lotus, which grows out of mud and does not dye. It is graceful and graceful. It emits its fragrance, which makes many people stop. It did not deliberately go to packaging, there is no great momentum to do publicity, why! Let's look at the topic first. The good title is the eyes of the song& quot; True heroes & quot; These four words are very attractive in themselves. What kind of people are heroes! Does the author want to show us the combination of gun, sword and fist through the deafening jazz; Hero & quot; Is that right? That & quot; Sincerity & quot; What is the explanation of the word? Turn on the radio with doubts and curiosity, and you will hear a gentle rhythm. Until the end of a song, I found out how old my way of thinking is! With his understanding of life, the author reinterprets the definition of hero - true hero: he says that we should first have broad love, the disseminator of truth, goodness and beauty; Secondly, he should have the courage to fight and be a strong man in life. Perhaps, you think, he has a strong sense of preaching, then, please continue to taste, you will certainly feel ridiculous for their own ideas& quot; In my heart, there was a dream to let you forget all the pain with singing& quot; The friendly and beautiful opening remarks bring people into a dreamy atmosphere, but the language is not flashy at all. To sit face to face with you, tasting a cup of tea, heart and you frank conversation. Tell you the hope you once had and the innocence you always showed. Perhaps, & quot; No hate, no pain, I hope there is love everywhere& quot; It's a little far away, but you never think it's naive. Because this is a kind of most sincere emotion, we may have had, in the innocent childhood. Just one day, you overhear and witness a kind of ugly behavior, so the crystal like wish is broken. When you hear someone talk to you again, the heartstring will be stirred to arouse your desire for sincerity and kindness. Isn't friendship what we expect? And Jackie Chan sang that sentence, & quot; Who is the real hero in the starry sky? Ordinary people have moved me the most;. Seemingly simple, it contains a profound truth. In fact, we are all ordinary people. Whether we are superstars or street vendors, we all have enviable shining points, but also a dark side. Who can be called the world's favorite, and who can say that looking back on the road, we find that the most ordinary is the most true. When we are still intoxicated in the first part of the true feelings and dreams, the four men have sent us a wave
