Isolation and decentralization

1. The most popular is bitcoin. Bitcoin has been popular for a long time. It can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
in China, the other one I know is the network mutual aid blockchain, which represents the platform of concentric mutual aid. Blockchain technology is used to solve the shortcomings of the network mutual aid instry. At present, blockchain is also very popular in the network mutual aid instry.

It's said that the currency circle has been going on for one day and the stock market has been going on for one year. Although it's a bit exaggerated, it's not unreasonable. In recent days, bitcoin has gone up sharply, but it has come down slightly today. It's estimated that no one can match the speed of the bull bear conversion in the currency circle. However, among many virtual currencies, how can we find high-quality projects? Xiaobian thinks that the bull market is not surprising. The key point is that the bear market still insists on giving weekly reports, at least for the projects with reliable teams. Today Xiaobian still brings you weekly reports of some high-quality projects. The following is the latest weekly project progress report (April 9-April 15, 2018) released by ubtc team. The specific information is as follows:

about ubtc:

unitedbitcoin, referred to as UB, code ubtc. UB is not only an upgraded version of bitcoin, but also a leading global blockchain ecosystem. UB is headed by Jeff garzik, a veteran of bitcoin, a core developer of bitcoin and a leader in the blockchain field

UB 100% inherits bitcoin's blockchain and upgrades and optimizes it. The upgrade and optimization of Ub include expanding the block size to 8MB, supporting segwit isolation witness, adding smart contract and lightning network, etc

UB is committed to bringing the inactive bitcoin credit into full play. Finally, based on these credits, we can issue stable currency anchored by legal currency, which can be used in a wide, fast, efficient and intelligent business society

more than 18 trading platforms around the world support ubtc trading

3. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.

4. Bitcoin isolation verification simply means that there is an additional side chain. The main chain and the side chain complement and support each other. Isolation verification is to solve the problem of bitcoin congestion. At the end of 2013, the problem of bitcoin congestion has appeared, and the expansion has become the consensus of the community, but there is no consensus on how to expand
in 2016, the community held a meeting in Hong Kong on capacity expansion. At the meeting, China's absenteeism and bitcoin core reached a consensus and proposed a compromise scheme, namely hard fork and isolation certification. This is the result of compromise between the two sides, but later the core went back on its words and forced absenteeism to accept the isolation scheme, but did not expand the capacity. China mostly opposes the exclusion of isolation verification.

5. Bitcoin cash (BCC) is a new encrypted digital asset launched by viabtc based on bitcoin ABC scheme. It can be regarded as a bifurcated or competitive currency of bitcoin BTC.

6. Hanging order is the number of orders waiting to be bought and sold behind the five trading prices transmitted from the exchange ring the market trading period. Together with five trading prices, these ten data constitute the most original public data in the whole trading system

7. If there is a legal will, it should be done according to the will. If there is no will, it should be done according to the legal succession procere. It is necessary to explain the specific situation of your family, who is the registered house, and the specific situation of the heir

Japan, South Korea, India and other countries support bitcoin because they are optimistic about digital currency and blockchain technology itself. However, speculators inflate the price of bitcoin, making it more risky

according to a survey of Huo coin.com, 80.77% of bitcoin trading investors are in order to achieve short-term profits. They keep buying and selling along with the fluctuation of the price of bitcoin to earn the difference

Sheba Jafari, head of technology strategy at Goldman Sachs Group, recently released a chart Research Report, in which he predicted the trend of the price of the special currency in the next week. In the report, he pointed out that the digital currency is in a & quot; Impulsive & quot; Rising trend & quot; The fifth wave & quot; In the medium term, it is expected to further rise to as high as US $4827 in the short term

however, & quot; Once the complete five wave sequence is in place, theoretically speaking, the market will enter the correction stage& quot; In the world of digital currencies, it is not uncommon for prices to fluctuate by hundreds of dollars. Bitcoin hit a record high of $3025 in mid June, but fell by more than $1000 in the following month. It has risen again and reached a new high in the past two weeks. Analysts said that the reason why bitcoin prices ushered in this upward trend is that investors are optimistic about its prospects

is better

9. In my opinion, bitcoin is not a way of payment, it is just a virtual currency. In short, bitcoin can act as a general equivalent in some specific circumstances. As long as both buyers and sellers accept bitcoin as an exchange item, it can become a virtual currency. But this does not mean that it can be accepted by most people like Alipay and WeChat, forming a way of payment.
