Hashprevblock blockchain

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized 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 a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness

however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay

2. digital currency is an application of blockchain
blockchain is a new computing paradigm and distributed infrastructure, which uses fast chain data structure, distributed node consensus algorithm, cryptography and intelligent contract based on automated script code to proce, verify, store and transmit data. It can also be said that blockchain is a distributed ledger technology, which can provide decentralized trust mechanism in non trust environment, so that multi-party participants can conct secure trust transactions without intermediaries
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3. I don't know if it's a cheat. Anyway, I'm bragging about it. I always ask them to buy it. At the beginning, it's rising very well. It's suddenly plummeting these days. I should have hired a lot of people. Anyway, I didn't buy it

4. I seem to have been cheated, let me deposit 5000 activation, and then said that the bank card must be Bank of China, other banks activation is 10000, deposit withdrawal has not been to the account, said that the system upgrade next week, and then can not contact people! Thirteen thousand in all! Did you call the police? What did the police say? I don't think it's good to report to the police. I don't know if it's useful!

5. Hash algorithm and MD5 are all one-way hash functions. The difference is that the hash results of different source data may be the same, but MD5 will not be the same. That is: hash is many to one function, MD5 is one to one function. MD5 is generally used to verify the credibility of data, and sometimes it is also used for one-way encryption of password (but now this encryption result can be cracked).

7. It must be an illegal trading platform. Don't take part in its trading platform. The loss will be very severe.

8. Take subway line 8 to people's Square, transfer line 1 to Jinjiang paradise station, transfer to "Shimei line"

take subway line 8 to people's Square, transfer line 1 to Lianhua Road, get off the station and cross the overpass. You can take "Lianshi line" to Petrochemical bus station and get off. It's very close
I took this line once and felt very far away. I walked for 1-2 hours that time
