Block chain will redefine the world __ programmers

Block-chain technology is considered to be the core technology of the next generation of power plant, electricity and Internet. If the steam engine released people's productivity, electricity to solve the basic needs of people's lives, the internet has completely changed the way information transmission, then the block chain as the construction of trust machine, will be able to completely change the whole human social value transmission way.

Block chain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm for building trust and acquiring equity between different nodes in a block chain system. meaning

In a narrow sense, the block chain is a kind of chain data structure, which is combined in order by time sequence, and the tamper-proofing and non forgery distributed ledger books are guaranteed by cryptography.

In a broad sense, the block chain technology is to use block-chain data structure to validate and store data, use the Distributed node consensus algorithm to generate and update data, use cryptography to ensure data transmission and access security, A new distributed infrastructure and computing paradigm that uses intelligent contracts made up of automated scripting code to program and manipulate data. three great changes brought by block chain Technology

First: Machine Trust
Second: Value transfer
Third: Intelligent contract Development

Block chain was born from the Ben Cong bitcoin, since 2009, there have been a variety of analog special currency of the digital currency, are based on the public block chain.

The current situation of the digital currency is to blossom, listing some common: Bitcoin, Litecoin, Dogecoin, Dashcoin, in addition to the application of money, there are a variety of derivative applications, such as Ethereum, Asch and other low-level application development platform and Nxt,sia, Bit stocks, maidsafe,ripple and other industries applications.

January 20, 2016, the People's Bank of China Digital Currency Symposium announced a phased outcome of the study of digital money. The meeting affirmed the value of the digital currency in reducing traditional currency issuance, and said the central bank was exploring the issue of digital currency. Lilin, founder of China's bitcoin trading platform, said the PBOC's digital currency seminar had greatly enhanced confidence in the digital currency industry. This is the first time after the December 5, 2013 Central Bank issued a notice on the prevention of the risk of Bitcoin, a clear attitude to the digital currency.

December 20, 2016, the digital monetary union-China Fintech Digital Monetary union and the Fintech Institute of the formal preparation, the fire currency is one of the joint initiator units. some areas that can be used in block chains can be:

▪ smart contracts

▪ securities trading

▪ e-commerce

▪ Internet of things

▪ social communication

▪ file storage

▪ proof of existence

▪ authentication

▪ equity public financing

We can make the development of the block chain analogy to the development of the Internet itself, the future will be on the Internet to form a thing called finance-internet, and this thing is based on the block chain, its predecessor is Bitcoin, that is, traditional finance from the private chain, industry chain (LAN) , the Bitcoin series from the public chain (WAN), all express the same concept-digital assets (Digitalasset), eventually to a middle equilibrium point convergence. the evolutionary way of block chains is:

▪ block chain 1.0--digital currency

▪ block chain 2.0--digital assets and intelligent contracts

▪ block chain 3.0--dao, DAC (block chain self-consistent organization, block chain self-contact company) –> block chain Big Society (science, medical, education etc, block chain + artificial intelligence). block chain is a super platform

1th Feature: Trust costs that are close to zero.
The 2nd-largest feature: The marginal cost of structuring and trading assets is approaching zero.
