Is Google document a blockchain technology

1. The relationship between jinwowo analysis blockchain technology and big data is as follows:
the relationship between blockchain and big data is not very big. The main purpose of big data is to manage massive data, and the core of blockchain is to achieve high security and high reliability of data without centralized intermediary accounting
therefore, blockchain and big data do not conflict with or replace each other. They are completely different solutions for data in different scenarios.

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. Explain blockchain with scientific language -- blockchain is a permanent and irreversible modified record generated by stacking (chain) encrypted data (blocks) in chronological order. It is a kind of credit certificate formed by computer encryption technology, that is to say, blockchain technology is a mechanism to solve the trust problem of strangers. Generally speaking, when there is no trusted third party, all transaction data will be stored in a data block, and the transaction information will form a complete chain to be included in the block chain. Then all data will be generated by computer encryption, which is a more reliable ultimate solution than the trusted third party

one of the characteristics of blockchain is decentralization, and the other is that it cannot be tampered with. Bitcoin, lightcoin, Ethereum and decent are all like this.

4. Yes, as an excellent blockchain enterprise, qubu company was introced by Chongqing municipal government. The candy accounting of qubu is based on the blockchain technology. The candy is obtained by the user on foot, which is clear and more secure.

5. Blockchain is a concept. Blockchain technology is not only the technology to realize the concept of blockchain, but also the code. Bitcoin is based on the concept of blockchain and developed with blockchain technology.

6. At present, there are many such teams, and the blockchain is suitable for all walks of life, but before the early cooperation, we must pay attention to the team strength and effect. The baker chain blockchain that we understand has a good evaluation in the instry, good reputation and good performance in all aspects. The evaluation of the instry is quite high.

7. It turns out that it's a dead rabbit. I coughed again, moved closer to the fire, and commented on the bad weather tonight
