Challenges of blockchain to government organizations

1. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

2. According to the analysis of jinwowo group, the problems faced by the smart contract based on blockchain are as follows:
1-security problem: one of the key problems is security and trust. The smart contract system is designed to be an environment without trust, which means that the mistakes can not be corrected
2 - Privacy: one of the challenges of effective use of blockchain is to provide thorough transparency
3 - unexpected scenario problem: smart contract sounds very good, but how to correctly and appropriately handle the contract execution in unexpected scenarios is a problem.

3. At present, the current situation of blockchain technology development in China is that there are more patents, less paper code, no independent security controllable underlying platform, and no integrated platform of software and hardware, which will directly lead to the technical risk of blockchain core technology being controlled by others, the financial risk of foreign open source platforms seizing the financial market, and the economic risk of foreign open source platforms penetrating China's real and virtual economy. Therefore, it is very important to realize the landing of blockchain application as soon as possible. Now there are landing applications all over the country under the support of policies. Changsha high tech Zone has officially launched a blockchain project, which is called SMIC blockchain service platform. It is a government enterprise service platform, cooperating with Bank of Changsha and Dean justice, and now it is the stage of collecting enterprises to join the chain.

4. mining

you want to make fun of this graphics card

5. Maybe, if you dig up krypton gold again and again, you'll make a lot of money. It's usually less than 100 grams an hour.

6. The mines in Outland should be the most valuable, but it's hard to mine, and the mines in pandaliya are also good
under the ideal situation of big bird mount + no one grabs the mines with you + opposing camp doesn't kill you + familiar with the mines, more than 1000g per hour
under normal circumstances, e to various interference factors, 500g per hour is good, minus 200g per hour, the actual income is 300g per hour, If you are engaged in manual mining, you should also consider the fatigue factor. The more mining, the lower the efficiency. It is not recommended to use this lowest level method of earning money. Just like the wage earners in big cities, they can barely earn a living (point card money), but they have no future

7. Treasure currency, light currency trade, light currency trade flexible, high safety factor, you check it online

8. Blockchain is like a "double-edged sword" for the government and the public sector: on the one hand, the characteristics of the distrust of blockchain bring challenges to the government, banks and other "trust intermediaries"; On the other hand, the underlying philosophy of distributed consensus, open source, transparency and social cooperation of blockchain technology represented by chainnova will bring more obvious advantages to the government and public sectors. It is necessary for the government to participate in the development and supervision of blockchain. It is necessary to understand the potential of this technology as soon as possible, introce innovative solutions, and provide better public services for the public.
