What about blockchain shutdown

3. If you lose the mnemonic words in the digital currency wallet, it is almost equal to the loss of the private key. Mnemonic words are just a form of the private key that is easier to understand. If you lose the private key, it is almost equal to the loss of the digital currency in the wallet. With the current technology, it is impossible to crack it. Therefore, if you forget it, you can only recognize it. Change the wallet and back up the mnemonic words

Blockchain itself is not illegal, but if it is used illegally, it is illegal

Li Bin, deputy director of Chongqing big data application and development administration, said that as a disruptive innovative frontier technology in the field of big data intelligence, the Chongqing municipal government attaches great importance to active layout, and the municipal government and Yuzhong District Government jointly build a blockchain base. In the second half of last year, the government issued the opinions on accelerating the cultivation and innovative application of blockchain instry, It has officially launched the construction of a place for strategic innovation of blockchain

while actively encouraging the technological progress and instrial development of blockchain, we will resolutely prohibit the illegal use of blockchain technology in accordance with the requirements of relevant national policies

at present, China's blockchain technology and application continue to innovate, and are graally applied in supply chain finance, credit reference, proct traceability and other fields, with huge development space. As a new technology, if blockchain wants to realize large-scale practical application, it must strengthen the cooperation of instry, University, research and application, and promote the continuous development and maturity of technology and application

since 2017, the development of blockchain technology has aroused the deep concern of the government, enterprises and other sectors. Because of its decentralized, tamperable and traceable characteristics, blockchain attracts investors to add weight to this new technology field. For the previous hot speculation of blockchain technology, the cognition of it and investment circles has become increasingly rational

5. To be honest, there's no way. Ethereum will exceed 2T, even if only some blocks are synchronized, it will take 20g. And now it's blocked and dissatisfied, and it's bound to collapse

6. The increase of blockchain network information is bound to need expansion, but it is not limited to a BTC public chain. No matter which public chain develops to a certain stage, it needs expansion technical support network. Therefore, it can be said that expansion is a necessary link for the implementation of blockchain scheme
the expansion of blockchain is the general trend, but there are differences in the specific operation. According to the different levels of blockchain architecture, the instry has proposed a number of expansion solutions: first, optimize the data transmission protocol for the underlying data layer of blockchain, do not change the upper structure of blockchain, and improve the scalability, such as bloxroute, the 0-layer expansion scheme of blockchain; The second is to change the data structure and consensus algorithm to improve the scalability of the basic protocol of blockchain, such as DAG (directed acyclic graph), fragmentation, dpos algorithm, etc; Third, aiming at the application level, such as side chain, sub chain, state channel lightning network and so on, part of the on chain transactions are transferred to the off chain execution to rece the on chain processing pressure and improve the overall efficiency.

7. This requires access to professional advanced defense companies for protection. 1. It depends on whether it is DDoS traffic attack or CC attack. Traffic attack prevention is relatively rough and simple. Most companies compete with bandwidth resources for this kind of local protection. But in the event of CC attacks, few can be prevented and the protection effect is good. 2. Ruisu cloud professional network security company reserves 4T + high defense bandwidth resources. CC protection is based on the unique signature analysis technology, customized protection according to the characteristics of the attacked, and cloud protection. It is not limited to the source server area. It can quickly access our ruin protection system within 10 minutes, and can do the protection of various application systems, such as four layers and seven layers, to help a lot of chess and card Virtual currency exchange, payment, e-commerce and other well-known customers successfully resist hacker attacks. 3. Free access protection running in, protection effect is satisfied, and then the formal cooperation.
