Security inspiration of bitcoin to blockchain
when the financial crisis broke out in 2008, a pseudonym named "Zhongben cong" published a paper to improve the story of Lao Wangcun based on blockchain Technology:
1) because bitcoin is global circulation, the "Yuan" in the story was changed into BTC, 100 yuan = 100btc
2) anonymity of bitcoin, Everyone in the story will announce how much money you have in your pocket to the world in the way of accounting. Presumably, everyone is not willing to put it into the account. Everyone in the bitcoin network has a wallet address, which is a code composed of several binary numbers
3) improvement of transaction mechanism and bookkeeping optimization
What are the current application scenarios of bitcoin< At present, the total market value of bitcoin is 967.236 billion, accounting for 50% of the total market value of cryptocurrency. If you are a 20-50-year-old Chinese and have a stable job, you know the news of bitcoin rising from 3000 to 8000 in half a month on the Internet hot search. At this time, you happen to see my article. Then you must think of one thing: should this thing be invested? And the risk
in my opinion, bitcoin is more suitable for fixed investment (if you invest a part of your salary in bitcoin every month, if you get 4000 salary, you can invest 300 at a fixed time point every month). In the cryptocurrency trading market, some people sell their houses because of bitcoin's sudden wealth, while others sell their houses because of speculation in bitcoin, The total market value of the cryptocurrency trading market is not large. There are indeed some experts, big and small, pulling the market, and the change is unpredictable. However, throughout the development of the past 10 years, cryptocurrency still presents a state of benign development, and more and more countries recognize it.
bitcoin is regarded as the first generation application of blockchain technology and the most thorough application of its code testing. However, without bitcoin, there might not be so many people who knew about blockchain now. It can be said that bitcoin has greatly improved the "exposure" of blockchain technology
later, people graally found that the application value of blockchain is far more than bitcoin, but can be applied to many instries to solve the pain points of many instries; The idea of blockchain can also provide a lot of reference for the financial field, which is the real reason for the outbreak of blockchain.
Blockchain technology is the underlying technology of bitcoin. Bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted out, which is called blockchain technology or distributed ledger technology
bitcoin is the first application of blockchain, which will be extended to more and more instries in the future
blockchain technology, known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records
However, bitcoin is a kind of currency that does not rely on specific currency institutions to issue. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation 
extended data:
characteristics of bitcoin currency:
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms
reference: network blockchain network bitcoin
blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain. As mentioned earlier, the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
if we compare the blockchain to a physical account book, then each block is equivalent to a page in the account book. A new account book is generated every 10 minutes, and the transaction information of bitcoin network is recorded on each page. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain
since the white paper "bitcoin: a peer-to-peer e-cash system" was born, major financial institutions at home and abroad have been competing to study the underlying technology of bitcoin blockchain and seek the practical application of blockchain technology.
