1. The essence of blockchain is a decentralized distributed ledger. Every transaction is recorded in this account book, and each participating node has one , so as to prevent the account book from being tampered with. Data loss will not be caused by the failure of a single node (such as the centralized server of the bank), and it can exist forever
it establishes a set of consensus mechanism to ensure the authenticity of data, and establishes trust between nodes that do not know each other. The participating nodes work together to maintain the healthy growth of the system
in order to stimulate the enthusiasm of participants, bitcoin, the first application of blockchain, was created.

2. The era of blockchain 1.0 is the era of digital currency, and the technical basis is:
1. Lianzhuang data block structure based on blocks
2. Network wide shared ledger
3. Asymmetric encryption
4. Source code open source
blockchain 2.0 era technical basis:
1. Smart contract; It is an application in the blockchain system. It is a business logic that can run automatically by coding. It usually has its own token and special development language
2. DAPP: it includes the user's applications, including but not limited to various cryptocurrencies, such as Ethereum wallet
3. Virtual machine: used to execute the compiled code of smart contract. Virtual machine is Turing complete
with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. The mode of blockchain cooperation can be seen from behind the operation of all walks of life. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology
of course, 3.0 came into being with the development of modern cryptography. Today's applied cryptography is the result of cryptography 20 years ago. Therefore, in order to apply blockchain technology to more participation scenarios, especially in Internet economy and other aspects, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed.

3. Buy bitcoin and build the next okex app. It supports buying currency, spot and various derivatives trading, Chain Wallet, mine pool, etc. I have been trading in okex for 2 years and have no problems. Don't understand can ask oh, wish you work smoothly
4. So far, it seems that Guo Jia hasn't said that any digital currency is illegal. It's just that the value is high or low. For example, the British Saipan coin has noble blood, and the famous bitcoin has not made many billionaires
5. Taking zhubajie network platform as an example, blockchain technology has played a role in the field of service transaction, quietly providing strong technical empowerment for service transaction protection. In zhubajie, blockchain technology has helped many users provide service transaction protection and right protection.
6. Blockchain is an important concept of bitcoin. According to the 2014-2016 global bitcoin Development Research Report released by fire coin and Internet Finance Laboratory of Wukou School of finance of Tsinghua University and Sina Technology, blockchain is the underlying technology and infrastructure of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
domestic blockchain application platforms include digital currency crowdfunding platform, asset custody system based on blockchain technology, which is jointly developed by coin Ying China, China Post and IBM.

7. 1 - disintermediated trust, which has been repeatedly emphasized, is not decentralization but disintermediation
2-stability, reliability and persistence. Because it is a distributed network architecture, no central node can be attacked or attacked, it has stronger stability, reliability and persistence in the overall technical layout
3-strong security, consensus mechanism does not need the entry of a third party, but through one technology to achieve the completion of the whole transaction
4 - is the guarantee of the openness, transparency and non tamperability of the transaction
the above four points are the characteristics of blockchain technology analyzed by jinwowo group!
