Dongfang xiongan blockchain

1. We can only talk about domestic examples. High quality application platforms such as the blockchain rental platform in xiong'an New District of Hebei, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan are the first to lead into the era of blockchain 3.0.

2. Xiong'an new area, Guangdong, Guangzhou, Shenzhen, Foshan and so on should be known by many people, but there is also a blockchain in Hunan Province in China, which is developing very well. Changsha, Loudi and Zhuzhou in Hunan Province all have the application of blockchain in government affairs, and all have made good landing effect. Changsha's SMIC blockchain public service platform has tens of thousands of Changsha local enterprises on the chain, and Loudi's blockchain real estate registration platform also has hundreds of thousands of real estate on the chain. You can learn more about it.

3. Australia, Japan and Canada are all developing well. For example, in Japan, even the government has begun to apply the blockchain technology. Some of their government affairs, such as government bidding, are completed on the blockchain platform. There are also high-quality blockchain government affairs platforms in China, such as the blockchain rental platform in xiong'an New District of Hebei Province, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan Province. They have done well and achieved good results.

4. Several successful ones are block chain housing rental platform in xiong'an New District, SMIC block chain public service platform in Changsha high tech Zone, and block chain Real Estate Registration Platform in Loudi. Hunan has done a good job in the application of block chain technology in the whole country. There are mature and successful application cases in provincial capitals and prefecture level cities.

5. Xiong'an blockchain can't log in. You can refresh it or reload the system.

6. Xiongan released new news, xiongan has put a lot of practice in blockchain application
among them, xiong'an group of China launched xiong'an blockchain fund management platform, which is the first project integrated management system based on blockchain technology in China; In June this year, China's first "blockchain supply chain" subcontractor financing business was successfully implemented in the flood intercepting channel phase I project in Rongcheng Rongdong area of xiong'an new district

in xiong'an, BIM (building information model) + CIM (city information model) technology has been adopted since the first urban construction project, realizing the co growth of physical city and digital city. Not long ago, China xiongan group said in the exchange meeting with consensys (Ethereum), a blockchain technology company, that xiongan will provide a broad experimental platform and application market for the development of blockchain technology in the future.

Nokia 5800 XpressMusic's user interface,
has a natural advantage in playing video compared with the iPhone's 4:3 resolution. The standby interface of S60 fifth edition has three modes -- general, finger touch and business card bar“ The difference between "finger touch" and "normal" is that there are four more buttons on the top of the screen that can be touched. At the bottom of the screen are a dial, a contact button and three virtual soft keys. At this time, the S60 menu key is in the middle of the three keys on the keyboard. Click to open the 5800 XpressMusic menu. The menu icons that can be displayed under 3.2 inches are quite rich. In addition, they can also be displayed in the form of a list. It is worth mentioning that in the opening mode of the secondary menu under the main menu, the fifth edition of S60 used by Nokia 5800 XpressMusic uses double-click operation, so when you get the 5800, if you can't open the menu, try double-click like a computer mouse. The "balance sensor" and "touch screen vibration feedback" are two extremely important user-friendly functions in the details of the user interface, which are completely inherited by Nokia 5800 XpressMusic. When the fuselage is placed horizontally, if the relevant settings are turned on, the screen will be placed horizontally automatically after an animation effect; At the same time, when operating 5800 XpressMusic, the fuselage will give obvious vibration feedback<

The built-in player supports music playing in mainstream format, and can automatically search songs according to artists, albums, genres and other factors. Its function is consistent with the multimedia playing of N series mobile phones. The Nokia 5800XM is equipped with a 3.5mm headphone interface, which makes it easy to replace high-quality headphones
the Nokia 5800XM is equipped with two speakers on the left side of the body, which are located at the top and bottom of the body. These two loudspeakers are very reserved in appearance. But the actual effect is very shocking, not only the volume is big enough, but also the effect is very good. Far more than the iPhone's speaker effect, it also has an advantage over the flagship model of the N series
5800XM is as powerful as the camera. The camera interface does not support full screen viewfinder comparison
