Time stamp technology of blockchain

1. digital currency will not be stolen in general. If you use a regular wallet and invest in a regular digital currency, there will be no problem!
2. In order to prevent the double spending problem, the system will automatically time stamp the transaction information of each block and mark it with time brand. How much money you spend at this time is spent. It has been recorded and can't be used to buy other things
how to record it? In fact, the time stamp and other transaction information on the block are calculated to obtain an encrypted value, which is called "hash value". Each new block contains the hash value of the previous block, thus forming a blockchain
so we say: bitcoin system is actually a layer by layer nested, never-ending, very powerful timestamp system, which uses timestamps to ensure that each block is linked into a "chain" (that is, block chain) in chronological order
from this point of view, time stamp literally means to time stamp a block. Its practical function is to provide an important parameter for later hash value calculation, which is an essential and very important information in the process of calculation and verification
finally, we summarize the content of this section. This section mainly introces two terms: utxo and timestamp. These two concepts are important means to solve the "double flower problem", which can ensure that bitcoin can not be used many times without a third party organization.

3. In short, timestamps prove what happened at what time on the blockchain, and no one can tamper with it. Blockchain ensures that each block is connected in sequence by timestamp. Time stamp makes every data on the
blockchain have time mark
blockchain have time mark
4. A timestamp, usually a sequence of characters, uniquely identifies the time of a moment. Digital time stamp technology is a variant of digital signature technology
time stamp refers to the total number of seconds from 00:00:00 GMT on January 1, 1970 (Beijing time: 08:00:00 GMT on January 1, 1970) to now
to put it simply, a time stamp in a blockchain means that whatever happens at a certain time will be recorded on the blockchain. For example, the blockchain content publishing platform decent, when someone publishes some information on it, the information will be recorded from the moment of release, which can't be changed. The time of occurrence is fixed and can't be changed.

5. The rest is king, survival of the fittest, a new opportunity for the whole people to raise cattle
one or 12 years is a cycle, 60 years is a Jiazi
all things can't escape the cycle law. P2P can not escape this cycle: germination, growth, prosperity, frenzy, bankruptcy, rebirth
P2P has been growing in China for 12 years, and this seedling, like a weed, grows in China
today's P2P is like a jungle, where a fire strikes and a large number of weeds die. Only a few towering trees can survive. After the disaster, P2P will be reborn
it is more important than ever to return to common sense and re recognize
without support, reckless companies are bound to be eliminated, and the lending of financial intermediaries is just a market rat
in the short run, this round of "Thunderbolt" event in the whole online lending instry has brought asset losses to "Thunderbolt" investors to a certain extent, affected the short-term investment sentiment and panic psychology of the majority of investors, and also caused widespread concern from all walks of life
however, in the long run, this round of "Thunderbolt" incident is a market clearing and effective release of the risk of illegal platforms with "original sin" in the early stage. It is a benign direction for good money in the market to drive out bad money, which is concive to the more standardized and healthy growth of the whole instry in the future
only after experiencing the baptism of fire bath, the instry will be reborn and a truly healthy company will emerge
traditional P2P will graally decline and disappear under the flood of Internet
as an Internet entity trade, cattle raising by the whole people will rush into the torrent, responding to users and the market with their real procts and sincere services
two, inflated to the maximum, often the biggest bubble.
at the end of last year, the official notice on the rectification and acceptance of the special rectification and rectification of P2P network lending risks (No. 57 document) clearly put forward that the deadline for rectification and acceptance and subsequent filing and registration should be June 2018
however, by June this year, the filing did not arrive as scheled< However, pan Gongsheng, vice governor of the people's Bank of China, pointed out at the mobilization meeting for the next stage of the work of the special rectification of Internet finance that it will take another one to two years to complete the special rectification of Internet finance risks, dissolve the stock risks, eliminate the potential risks, and initially establish a regulatory system to adapt to the characteristics of Internet finance
P2P platforms are calling for the implementation of the filing scheme, but most of them do not meet the compliance requirements
if we say that the P2P platforms that collapsed around 2015 are Ponzi scheme, illegal fund-raising, financial pyramid selling, and evil lending, such as the huge e-leasing event and the "naked" event of lending treasure
well, this time some of the top P2P platforms are running away and closing down
as of June 2018, a total of 5983 P2P platforms have been monitored, of which only 1504 are in normal operation, accounting for only 25%
compared with banks, they must have higher technology efficiency and better risk control management, which most P2P platforms do not have< Third, the whole people's cattle raising is the transaction of physical beef procts, which is totally different from the P2P Internet financial intermediary recently
moreover, all the funds of the national cattle raising enterprises are not lent or wasted. They are all used for offline stores and beef trade services, and each service generates profits
consumers should rationally distinguish between P2P and other Internet procts, and keep rational choice. Good money will eventually drive out bad money. We will keep the good status quo of cattle raising and seize the opportunity to open up a broader market for beef<
