1. "blockchain" is an important concept in the new era. In essence, it is a centralized database, and also an underlying technology such as digital currency. According to our popular explanation, "blockchain" can be regarded as an account book. Every bill is every block, but this account book is centralized, and it can be said that no enterprise or team has jurisdiction over it“ "Blockchain" technology is a unique information technology, such as centralization, information can not be changed in series. Now this technology has been applied to a series of applications such as electronic invoice, payment code and so on
in today's life, many people use this pretext to cheat, such as direct selling, capital, technology, etc. There is no right or wrong in technology, but in people
with the progress of the times and society, the beginning of the application of any technology will be questioned positively and negatively. However, with the relative application and maturity of technology and the improvement of technology, the various applications around people will continue to improve. I believe that in the near future, these doubts will graally dissipate
the following is a summary of some blockchain scams around us
trap 1: block chain is the coin trap
trap two: virtual currency transactions, promise low investment, high return
trap three: centralization can solve all problems
trap four: block chain extension procts can be laid down with a mining machine to earn money
trap five: WeChat, Alipay trading transactions virtual currency

2. At present, there are three application deployment types of blockchain: public chain, private chain and alliance chain. What's the difference between them? What are the typical applications<
public chain: open to all, anyone can participate
private chain: open to indivial indivials or entities
alliance chain: open to specific organizations
public chain: open to all, anyone can participate
private chain: open to indivial indivials or entities
alliance chain: open to specific organizations
3. Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true
blockchain can improve the way of data recording in audit. In the current network audit, although there is an early warning mechanism, it still needs auditors to judge and handle the abnormal records manually; Blockchain can automatically process the abnormal records through whether each node verifies and approves the block and the transaction information in it, whether the network node is attacked, and whether the account book of each node is complete, so as to make real-time audit possible. Auditors can directly access and query the effective information on the blockchain, judge whether the processing is reasonable and make corrections. In the blockchain, timestamps are used to record various transactions and operations, which can achieve historical traceability and tracking, and greatly improve the quality and efficiency of audit
blockchain can change the storage mode of audit data. In traditional audit, data are stored in an audit center server, which not only has the problems of high load and slow running speed, but also is vulnerable to attack; The blockchain audit system is a typical distributed storage, each node has the same backup, which can not only save the high cost and maintenance costs of the server, but also ensure the integrity of the data
semi public private chain can be used for audit. Blockchain can be divided into three forms: public chain, semi open private chain and full private chain. Considering the characteristics of audit instry, it is appropriate to adopt semi open private chain mode. For the audited units and enterprises, some trade secret information is not disclosed, but the pre selected nodes within the group decide the generation of the block. External suppliers can participate in the transaction but not the accounting process. Externally, it provides a third-party query node to query through the open API. In this way, it can not only ensure the internal privacy of the enterprise, but also enable the external auditors to implement real-time audit query.

4. The distributed architecture and tamper proof features of blockchain technology help to solve the problems of bill authenticity and information opacity. When participants need to check whether the bill has been tampered or transferred, blockchain can provide indisputable proof of consistency
digital currency also makes use of this feature of blockchain. Puyin is a kind of tea standard digital currency developed based on blockchain technology.

5. If the tax is collected, it is equivalent to recognizing the currency status of bitcoin.
6. Of course, you can turn back gold coins. If you have gold coins, you can always recycle them to the innermost machine. There are many things in that gold coin.
7. What is blockchain technology
before discussing how to apply blockchain in daily life, let's talk about what blockchain is and how it works
blockchain is an open distributed database, which is essentially a computer file used to store information (data)
the name of blockchain comes from its structural characteristics: the file is composed of data blocks, and each block is linked to the previous block to form a chain. Each block contains data, such as transaction records and records when the block was edited or created. Information (data) is stamped with time stamp, which is the origin of blockchain
it is crucial that, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and data is completely copied (distributed) on multiple computers
because it is a decentralized way to store and access data, it becomes extremely secure. Different from the centralized database, the attacker does not have a single entry point, so the data security is more guaranteed<
in addition to the two characteristics of decentralization and security, blockchain has become a leading technology which is different from other technologies:
tamperability: once entering the blockchain, any information can not be changed, even the administrator can not modify this information. It makes blockchain easy to audit
accessible: all nodes in the network can easily access information
no third party: blockchain can help point-to-point transactions, so whether you are trading or exchanging funds, you do not need the approval of a third party. Blockchain itself is a platform
the impact of blockchain technology
first, the open and tamperable nature of blockchain technology makes it possible to decentralize the trust mechanism. It has the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, bills, warehouse receipts and fund shares, can be integrated into the blockchain ledger to become digital assets on the blockchain, which can be stored, transferred and used in the blockchain Deal. It has a broad application prospect in the financial field. For example, it has typical applications in cross-border payment, insurance claims, securities trading, bills, etc
Second, the current Internet of things ecosystem relies on the centralized network management architecture, and all devices are connected through the cloud server. With the expansion of the network scale, the infrastructure and maintenance of centralized cloud servers, large servers and network equipment will occupy a high cost
in the decentralized Internet of things, blockchain is a framework to promote transaction processing and cooperation among interactive devices, and each device on the network can operate as an independent and micro business entity< Third, public service is a factor to promote economic growth and social progress. The supply of public service has an important impact on various subjects, systems, cultures, attitudes and behaviors in the process of political, economic and social development. The traditional notarization relies on the government, and the limited data dimension and the historical data information chain that has not been established often lead to the government and schools unable to obtain complete and effective information. Using blockchain, tamper proof can be established. In the fields of digital rights, intellectual property rights, certificates and public welfare, new authentication mechanisms can be established to improve the management level of public services.
