Blockchain originated from bitcoin in 2008

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention

related extension: blockchain financial application:

since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency

standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016

the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology

on June 1, 2020, Xinhua news agency was authorized to broadcast the "overall plan for the construction of Hainan free trade port" issued by the CPC Central Committee and the State Council, which will "actively participate in the formulation of international rules for cross-border data flow, and establish standards and rules for data rights confirmation, data trading, data security and blockchain finance" as one of the key tasks of Hainan free trade port before 2035

3. Satoshi Nakamoto, who calls himself Japanese American, is the creator of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin". In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins.

4. Blockchain is one of the technologies of bitcoin, which can be understood as cloud database.

5. When someone does something wrong, people's first reaction is to stop him. However, e to the factors of status and timing, sometimes direct check will have the opposite effect
I think the first step is to make sure that your parents are not deceived, because parents may be better at communicating. Then work with your parents to stop your uncle
I think you can find one or two professionals to teach your uncle, such as your teacher, and you can also find the content of online rumor refutation.

6. A new resolution initiated by representative Adam kinzinger, a Republican from Indiana, has been submitted to the US House of Representatives, calling on the government to formulate national policies on emerging technologies, including digital currency and blockchain technology
the resolution calls on the idea of bitcoin, but does not directly mention its name. Instead, it calls it "alternative illegal currency". Blockchain technology is the key point, which points out that this technology has the potential to "fundamentally change" the way trust and security are built on online transactions
but in fact, the United States has not taken action to formulate this rule. However, there is a global blockchain alliance R3 in the process of formulating the standard for the use of blockchain. Of course, blockchain is just a technology that can be used by any enterprise. In China, there is a project called decent, which is more avant-garde. It uses blockchain technology to build a decentralized content publishing platform, but it may encounter some problems in China.

On March 19, trump signed an executive order to prohibit U.S. citizens and entities or indivials and entities in the United States from participating in digital currency transactions concted by the Venezuelan government or its agents. The executive order came into effect at noon on March 19

since the second half of 2017, the United States has repeatedly imposed sanctions on Venezuela e to the holding of the constituent assembly election and other reasons, expanded personal economic sanctions on current and former senior officials of Venezuela, and prohibited U.S. financial institutions from participating in New debt and equity transactions between the Venezuelan government and state-owned Venezuelan oil companies, American institutions are prohibited from participating in the trading of some bonds issued by Venezuelan public sector

Blockchain is a technology used by bitcoin and a database technology

bitcoin is an application of blockchain and a digital currency

blockchain technology was born with the birth of bitcoin, but blockchain technology is not limited to bitcoin, or even digital currency, but has a very wide range of applications

In 2008, Nakamoto published a paper on bitcoin, commonly known as the white paper on bitcoin. Among them, the concept of blockchain was put forward in Nakamoto's white paper. A blockchain is a series of data blocks (called "blocks") generated by using cryptographic correlation. New data blocks can always be linked to the last block, that is, the end of the whole blockchain. Bitcoin's peer-to-peer network stores all transaction history in a "blockchain."

since the advent of bitcoin, more and more digital cryptocurrencies using blockchain technology have been introced, and up to now there are nearly 3000 kinds.

but in addition to the field of cryptocurrency, blockchain technology has been widely used in finance, Internet of things, logistics, insurance, digital right and other fields

9. Blockchain originated from bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article bitcoin: a peer-to-peer e-cash system [4], which elaborated the architecture concept of e-cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., marking the birth of bitcoin. Two months later, the theory entered into practice, and the first Chuangshi block with serial number 0 was born on January 3, 2009. A few days later, a block with serial number 1 appeared on January 9, 2009, and connected with the genesis block with serial number 0 to form a chain, marking the birth of the blockchain [5]
in recent years, the world's attitude towards bitcoin has gone up and down, but blockchain technology, as one of the underlying technologies of bitcoin, has been paid more and more attention. In the process of bitcoin formation, blocks are storage units that record all the communication information of each block node in a certain period of time. Each block is linked by random hash (also known as hash algorithm). The latter block contains the hash value of the former block. With the expansion of information exchange, one block is connected with another block one after another, and the result is called blockchain
