Value carrier of blockchain

1. Indivials can buy and sell bitcoin at their own risk

2. Most of the instrial parks have been established in the past two years, that is, the business hours are only one or two years. The main profit model still relies on obtaining policy subsidy funds. The main reason is that the blockchain application has not been actually implemented. I believe the situation will be better in the next two years. Now there is a blockchain project in Changsha high tech new area, which is called SMIC blockchain service platform, It is a government enterprise service platform, cooperating with Bank of Changsha, Dean justice, etc., and now it is the stage of collecting enterprises on the chain.

3. Many virtual currencies, once withdrawn from the exchange, have to be stored in third-party wallets such as imtoken. This is also forced helpless, because there is no own wallet, so can only "rely on others."
How can we live an independent life without looking at others? This will lead to a word: the main chain
the term "main chain" comes from the "main network" (relative to the test network), that is, the officially online and independent blockchain network
at present, among the top 50 blockchain projects in terms of market value, 12 projects are "main chain" (the current data has changed), and Ethereum is the most successful one
Ethereum is a main chain that has its own independent wallet and can "provide housing" for other currencies
next, through the analysis of Ethereum, we will give you an in-depth understanding of what is the main chain
most of the crowdfunding projects in the market are based on Ethereum. You can understand that Ethereum is a computer operating system, similar to the windows system, and the various tokens on Ethereum are equivalent to all kinds of software on our computers. Developers can pay Ethereum to run projects on Ethereum. However, Ethereum is not perfect. The more projects based on Ethereum, the greater the network demand for Ethereum. In serious cases, it will lead to congestion
in fact, most of the main chain projects are still in the stage of technology R & D and improvement, and there is still a long way to go before the real technology is implemented
the most fierce competition in the field of blockchain is actually the battle of "main chain". Whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
in addition, in the domestic public chain, the Walton chain is the underlying commercial application public chain, which combines the software level features of blockchain, such as decentralization and unforgivability, with the hardware of RFID chip independently developed, to provide traceability, authentication solutions, and design instry data encryption and distributed storage database building services for all walks of life
of course, it doesn't mean that projects with a main chain are better than projects without a main chain. Some projects, e to their nature, don't need a main chain, such as BNB, whose main purpose is to offset the handling charges in the currency exchange, so it doesn't matter whether there is a main chain
from bitcoin to Ethereum, and now to EOS, many gods are building the main chain, trying to climb the tide of the times. Who will be the future king of blockchain? Let time give us the answer.

4. There are many ways to open and close the back cover of a watch, but the screw back cover and press back cover are the most, followed by tightening the back cover with a few screws. For press back back cover of a watch, as long as we use some basic tools, we can open it. When restoring, we only need to press it tightly, which is the simplest in terms of disassembly
the back cover of the set press waterproof watch is special, and its upper case is pressed on the bottom cover. There is a high wall around it. The movement is installed in the wall of the back cover. The watch glass is directly installed on the wall of the back cover. After the upper shell is pressed in, the watch glass and the back cover are tightly covered, so as to play the role of sealing and waterproof
it's easy to have problems when installing the watch, and it's often difficult to close the back cover of the watch, so put the back cover on the hard board desktop. Put a soft cloth on the front glass of the watch and press it down with the palm of your hand. Adjust the position of the cover. If the notch is in the wrong direction, turn the cover down and the front of the watch up. In this way, the back cover of the watch will be installed back successfully. We should also use professional meter opening tools as much as possible, so it is recommended to take it to a repair shop to repair or replace it. It is on the 30th floor of Tianjin International Financial Center building.

5. 1. When building a set of accounts
2. An account set has only one functional currency. If you want to record multiple currencies in the transaction processing layer, use MRC; If it is not needed, it can be realized with conversion function or account set consolidation function
3. Of course, foreign exchange adjustment is for the reporting currency, so the report of each reporting currency should be the result of revaluation.

6. Yunnan metallurgy used to be called Gejiu Yunxi company, Dongchuan Mining Bureau, Yimen copper mine and Huize Lead zinc mine.

7. Let me summarize to the building owners that we can use the token to encourage and govern. For example, we can use weni to mobilize various types of community user groups and partners to build an ecosystem of consensus, sharing, win-win and autonomy.
