Blockchain history

1. The trend of the next era will also become the biggest bubble in human history.

2. This concept was proposed in the white paper [1] of Nakamoto Tsung, who created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Ruitai coin, Laite coin, dogcoin, Ethereum and other digital currencies will use blockchain technology.

3. The development of blockchain can be divided into three stages. Melanie Swann, founder of blockchain Science Research Institute, in her book blockchain: blueprint and guide to new economy, according to the application and development of blockchain, it can be divided into three stages: blockchain 1.0, 2.0 and 3.0< br /> 
I. blockchain 1.0 cryptocurrency era (2008-2013)
&
in 2008, Nakamoto first proposed the concepts of bitcoin and blockchain, and then in January 2009, the first blockchain came out. At this stage, people pay more attention to the transaction of cryptocurrency, and blockchain is only used as the underlying technology to act as a "public account book"< br /> 
2. Blockchain 2.0 smart contract era (2014-2017)
&
in 2014, & quot; Blockchain 2.0 "has become the pronoun of decentralized blockchain database. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute the smart contract on the blockchain, and will be rewarded automatically after the execution. Because this transaction process does not need any intermediary, so people's privacy has been greatly protected< br /> 
III. blockchain 3.0 large scale application era (2018 -)
&
at this stage, people begin to build a completely decentralized data network, and the application of blockchain technology is no longer limited to the economic field, but expanded to the fields of art, law, real estate, hospital, human resources and so on.

4. Blockchain is a huge gamble. Just imagine if the right to issue currency is not controlled by the Central Bank of a country, then everyone can become a rich man. This is a bit like before the abolition of the two reforms in the Republic of China, every place had its own unique currency in circulation, and even everyone's currency in circulation was different. This is not inflation proof. To put it bluntly, RMB is a piece of waste paper, but it has credibility

5. The origin of blockchain comes from "bitcoin: a peer-to-peer e-cash system" published by Nakamoto in 2008. According to this concept, the first proct "bitcoin" was born. The origin of blockchain technology is usually attributed only to the actions of some mysterious geniuses who work under the pseudonym of Nakamoto. This view of history often makes the technology seem almost magical and difficult to understand. When people understand the actual history behind the development of these systems, it is more fundamental. In this section, I will outline the most important topics in decades of research on consensus algorithms and distributed systems that led to the creation of blockchains.
