How to eat blockchain

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

blockchain money making methods:

1. Promotion to earn commission

the method of blockchain is to first register the exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates a transaction, you will have a commission

2

currency speculation is like stock speculation. Currency speculation is the lowest threshold for blockchain to make money

3. mining

Mining in bitcoin is the process of bookkeeping. This process needs to be tackled. If you seize the opportunity of bookkeeping right, there will be a reward. The reward is bitcoin. This behavior is called "mining"

4

wallet is the infrastructure of the block chain, just like the "Alipay" or "WeChat payment" of the block chain. p>

1. Blockchain is an important concept of bitcoin, which is essentially a decentralized database and 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

2. The blockchain was born from the bitcoin of Nakamoto Tsung. Since 2009, there have been various digital currencies similar to the bitcoin, which are all based on the public blockchain

On January 20, 2016, the digital currency seminar of the people's Bank of China announced that the research on digital currency has achieved phased results. The meeting affirmed the value of digital currency in recing the issuance of traditional currency, and indicated that the central bank was exploring the issue of digital currency. The expression of the digital currency seminar of the people's Bank of China has greatly enhanced the confidence of the digital currency instry. This is the first time that the five ministries and commissions of the people's Bank of China have expressed a clear attitude towards digital currency since they issued a notice on preventing bitcoin risks on December 5, 2013

blockchain network

3.

blockchain technology has the following four ways to make money:

1. Hardware and infrastructure. A typical one is mining machinery proction and distribution chain, where you can make money by buying mining machinery and digging

2. The underlying platform of blockchain and common technologies, such as Ethereum and other public chains, and the privacy protocol nucypher, where you can make money by investing in its token, building applications on the chain, and providing services for users

3. Various vertical applications, such as supply chain traceability and Finance Based on blockchain, right confirmation and trading, can be used or invested to make money

Service facilities, such as digital asset exchange and wallet, media procts, etc., you can make money by making your own exchange

type of blockchain

1. Public blockchain

refers to: any indivial or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, Anyone can participate in its consensus process

public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world

2. Consortium block chains: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction

3. Private blockchain

private blockchain: it only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and only enjoys the write permission of the blockchain. This chain is not very different from other distributed storage schemes
