1. blockchain is indeed the trend of the times. Investment in blockchain can be carried out from the following aspects:
1. Enter the blockchain instry and engage in relevant work. It's still in the early days, the circle is still very small, and it's easy for the same instry to get in touch with big men. If you can really settle down in this instry and continuously accumulate instry cognition, you will be the big man in three or five years, and you will have more resources in the instry, which will be of great benefit to your career and career development
2. The digital money market is the half proct of blockchain. All kinds of digital currencies, such as bitcoin, Ethereum, lightcoin, etc. in the past 10 years, the return on investment of these currencies is quite high, and bitcoin is as high as 8 million times. Therefore, from the perspective of investment, we can put part of the capital into digital currency, and there will be a good return in two or three years
3. The other is to start a blockchain business. This road is also the most difficult one to take. When you see other people issuing a coin and earning hundreds of millions of money, you may feel excited. However, it's much more difficult than you think to really start a business and contribute to the blockchain world. You have to explore everything by yourself, and it's easy to get lost. Therefore, we should be cautious in choosing the path of entrepreneurship
in fact, the best investment is to invest in our brain and strengthen our understanding of blockchain. No matter whether we enter this instry or not, we should be full of curiosity about this new thing and not miss this rare opportunity.

2. Xiao, who don't have much spare money, want to be big again. They pay thousands of yuan for the community such as Huo chain blockchain academy, and they can earn ten times as much when the market comes; Only bitcoin and Ethereum will earn the least, with little risk.
3. Blockchain is a kind of chain data structure that combines data blocks in order according to the time sequence, and it can't be tampered and forged by cryptography
virtual currency is simply a kind of digital currency using cryptographic algorithm, and virtual currency is invisible
the media of the central bank also said that private digital currency transactions will not be opened after the situation is stable

4. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

5. Indeed, there are blockchain wallets using this technology, such as IDC
wallet. In fact, mnemonics are another form of expression of the private key, which has the same function as the private key, mainly to protect your blockchain money

6.
The address itself is anonymous. Ordinary people can't find it. But if you register with the exchange, the exchange has your information and blockchain address
anonymity and traceability of blockchain addresses : anyone can easily generate a large number of private keys, public keys and addresses. The address itself is anonymous, which can be further improved by multiple address transactions. But all transactions are transparent, that is to say, all transactions at one address can be checked and traced. That is to say, I can track and query all the in and out accounts and balances at the address you give

7. No. Now the communication instry is developed, but personal information leakage is serious. It's normal to have such worries, which shows that people's self-protection awareness has improved. But the proct source chain is a high-tech, using the blockchain encryption technology, will completely encrypt the user's personal information, protect the security of the user's personal information, so, don't worry about this.
8. The data storage mode of blockchain is actually "block" + "chain". This is like our diary, each page is a piece of paper, on which useful text information can be recorded, but each page will have a page number to record the order of each page. In contrast, a block is "paper" to record all the value exchange activities that took place ring the creation period. Page numbers are "chains" that store blocks in the database in chronological order.
