Bitcoin transaction tracing
The remitter pays bitcoin directly to the recipient's address through a computer or smart phone
bitcoin transaction data is packaged into a "data block" or "block", and the transaction is initially confirmed. When the block is connected to the previous block, the transaction will be further confirmed. After six successive large amount confirmations, this transaction has basically been irreversibly confirmed
bitcoin peer-to-peer network stores all its transaction history in the "blockchain". The blockchain continues to grow, and once new blocks are added to the blockchain, they can no longer be deleted. Blockchain is actually a distributed database, which is composed of a group of scattered customer nodes and all participants. It records the history of all bitcoin transactions
{rrrrrrr}
extended data:
users can buy bitcoin, and then use computers to do a lot of calculations to "mine" them. When users "dig" bitcoin, the computer will search for 64 digit numbers, and then compete with other gold diggers to repeatedly solve the puzzle and provide the number needed by the bitcoin network. If the user's computer successfully creates a set of numbers, it will get 25 bitcoins
From 2012 to 2014, bitcoin swept the world, graally forming a "virtual currency" instry chain represented by bitcoin. This is a reform of the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and opens a new chapter in the history of the Internet. Bitcoin fund is one of the derivatives represented by bitcoin in the era of "virtual currency" FXCM China said bitcoin fund will open in autumn 2014. FXCM bitcoin fund, as the world's first mutually beneficial and win-win financial model, has a new look, but it is also full of temptations and challengesBitcoin blackmail refers to an email received in the mailbox. The content of the email generally includes: malicious software on the computer has captured the recipient's indecent photos through the webcam, knows the recipient's real password, etc., which makes the recipient fear and demands to pay the sealing fee in the form of "bitcoin"
if the blackmailer passes the email, he will take the next step, and he does have a lot of important information. In any case, don't transfer bitcoin to blackmailers. It's a bottomless hole. It's a good choice to keep all the evidence and report to the police. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again
You can see the flow of the transaction, but you can't be sure who the account corresponds to in the real world
a bitcoin account is an address, and an address corresponds to an account. However, there is no need for identity proof to open a bitcoin account. Everyone can open a bitcoin account, and the number of bitcoin accounts can be opened is more than that of sand in the whole world. A person can correspond to multiple accounts, so I don't know which person this address corresponds to, that is, anonymity
Transaction mode of bitcoin
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
historically, there has always been a long-standing problem in the high transfer market. For example, Nachuan shares, Cixing shares, and Zhongke hechen shares, which implemented the high transfer ring the mid-term report of 2012, all suffered from "death in sight" after the profit distribution plan was launched. Therefore, investors should pay attention to the high transfer potential stocks as soon as possible, especially in the current market downturn, Can be involved in bargain hunting, central line layout< The first stage is the guessing period, in which the market lists the potential stocks and carries out the speculation in turn; The second stage is the cash period. For the stocks that appeared in the first plan, the capital is often a lot of speculation, but the continuity of the market is generally not long; The third stage is the right filling period after the implementation of the scheme, but in the A-share market, the possibility of the high transfer shares to fill in the right is lower than that of the pasted right. Therefore, the first stage is the period of high transfer concept stocks with the most excess returns. Due to the fact that the market has just begun to pay attention to the high transfer theme, and the market is relatively weak, the stock prices of related stocks have not yet been fully started, so it should be a good time to lay out the high transfer theme stocks
the theme of high transfer can be analyzed in detail from the following five aspects: the extent of performance exceeding the expectation, the latest performance, the concentration of institutional holdings, the effect of large and small market, and the previous trend:
1. The larger the extent of annual performance exceeding the expectation, the higher the excess return may be< (2) the stocks with the latest EPS growth on the base date are more likely to obtain higher excess returns when the annual performance exceeds the expected< (3) the stocks that lose the market in the 60 trading days before the base date are more likely to get higher excess returns after the annual performance exceeds the expectation< (4) the stocks with a lower proportion of institutional holdings (30% or less) in the latest period from the base date are more likely to obtain higher excess returns after the annual performance exceeds the expected< (5) small cap stocks with less than 500 million freely circulating shares are more likely to obtain higher excess returns when their annual performance exceeds expectations. After the combination of the above five screening criteria, the optimal screening criteria for the stocks whose annual report performance exceeds the expectation are "small cap stocks with the latest institutional shareholding ratio of 30% or less and the annual report performance exceeding the expectation of more than 50%
although there are different listed companies that launch high transfer scheme every year, investors can still find stocks with high transfer potential from some financial data. Generally speaking, the listed companies that can implement high transfer have the characteristics of small share capital, accumulation fund per share, high undistributed profit per share and large performance increase. According to the analysis of the market situation in 2012, the listed companies with a total share capital of less than 500 million shares, net assets per share of more than 3 yuan in the first three quarters, provident fund of more than 2 yuan, undistributed profit per share of no less than 1 yuan, performance growth of no less than 30% in 2012 and no profit distribution ring the latest interim report are most likely to launch a high transfer scheme ring the disclosure of 2012 annual report. Combined with the information disclosed in the third quarterly report of 2012 and the notice of 2012 annual report, 110 listed companies such as Jiuzhou electric (300040) are expected to become high transfer stars ring the 2012 annual report period
the hype on the theme of high transfer has always been the traditional reserved program of the annual report. Under the background of the poor market in 2012 and the difficulty for investors to make profits through the trading spread, high transfer may be more attractive to investors, especially the introction of the differential dividend tax policy is expected to promote more investors to establish the concept of value investment, It is expected that high transfer, especially high dividend concept stocks, will become one of the main concerns of the market at the end of the year and the beginning of the year< According to the statistics of tonghuashun data Department, there are 18 listed companies in line with high delivery in 2012 annual report, which are: Xinjiang Haoyuan, Shouhang energy saving, kanudi Road, Zhongke Jincai, Xin motor, Keming flour, Dongjiang environmental protection, Jiajia food, Longquan stock, Tengxin food, Gongda electroacoustic, xuedilong, Anzhong stock Huanghai machinery, Baiyang Co., Ltd., maoshuo power, Mengshi technology, Changliang technology Figure)
Shanghai Shikai development (600748), BaoTi (600456), Xinjiang Haoyuan (002700), Shandong mining machinery (002526) and other stocks maintained relative strength. With the late rebound of the market index, they successively entered the trading limit list of indivial stocks. One of the common characteristics of these four stocks is that they have the potential of high transfer
investors are more likely to obtain excess return before the announcement of the plan, and the excess return is not very stable after the announcement of the plan, so Nuggets high delivery stock needs to be arranged in advance. In addition to identifying potential stocks through financial indicators, investors should also pay attention to whether the relevant stocks have feedback www.southmoney.com In the tradition of investors, many "iron roosters" in the A-share market have the ability to pay dividends on financial data, but they are unwilling to implement profit distribution. In order to rece the share price and transaction difficulty, secondary new stocks with higher share price often have the willingness to split the share price through high transfer
the essence of equity transfer is the internal structural adjustment of shareholders' equity, which will not bring direct income to investors. At the same time, e to the expansion of share capital, the conversion of capital reserve into share capital and bonus share will dilute the earnings per share. Therefore, cash dividend is "real money" for investors, and high dividend stock has stronger participation value. In addition, the performance is the key to support the stock price of listed companies, and high transfer can only play a role of "icing on the cake" on the stock price
1. The annual report is the first to appear on the stock market or has explosive power
ring the annual reports of A-share over the years, the stock prices of the first companies to disclose the annual report will be severely speculated. For example, Shenzhen high and small board listed companies essence Pharmaceutical (002349) pulled out the first annual report in 2010, essence pharmaceuticals in from January 4 to 5, 2011, continuous trading for two consecutive days. During the 2012 annual report period, Yingkou Port (600317) and St instrial took the lead in publishing the annual report. After the scheled disclosure date, both shares rose sharply. In addition, Xingmin steel ring (002355), which was first disclosed in the small and medium-sized board, rose continuously before December 30, 2011, and there were two trading boards again after new year's day
according to the rules of pre disclosure schele of annual report of Shanghai and Shenzhen Stock Exchange, it should be released on the evening of December 31, 2012, and the release of Shenzhen stock exchange can be earlier than that of Shanghai Stock Exchange. The pre disclosure schele of Shenzhen Stock Exchange was announced ring the day of the third quarter of 2012, which had enough event impact on indivial stocks in trading, so on December 31, 2012, Radical investors can focus on the whole day< As of December 19, 934 companies in Shanghai and Shenzhen stock exchanges have issued their annual performance forecasts for 2012, and the annual performance forecasts of 64 companies have doubled that of last year. For example, the performance of Huaxing Chemical (002018), Shuangjian Co., Ltd. (002381), conch profile (000619), Hengdian dongci (002056), Baotong belt instry (300031), Xuji Electric (000400), Guanghui energy (600256) and other companies will be greatly improved compared with the same period last year
it is a necessary part of the annual report market that the performance of stocks increased significantly in advance. The stocks whose performance forecast exceeds the expectation will cause the market to be hot. From some stocks with substantial growth in performance, we can ambush related varieties in the same instry. For example, this year's performance in the electrical equipment instry is likely to soar. Xuji Electric recently predicted that the maximum performance change this year will reach 120%, and Pinggao electric (600312) in the same instry is certainly good. There are also small and medium market value of real estate stocks will also appear some performance surge stocks
3. There must be a good play to watch with high delivery and transfer
the concept of high delivery and transfer is bound to be sought after by the market ring the disclosure period of this year's annual report. Based on the analysis of the characteristics of the stocks transferred from the annual report in the past three years, the probability of the stocks that have been highly transferred in the mid-term report of 2012 and those that have been implemented before is seriously reced ring the annual report of 2012. Therefore, most of the new stocks listed in 2012 and those that have not been transferred are more likely to be transferred ring the annual report
according to statistics, a total of 18 shares meet the conditions of high delivery, which are: Xinjiang Haoyuan (002700), Shouhang energy saving (002665), kanudi Road (002656), Zhongke Jincai (002657), Xin electric machinery (002664), Keming flour instry (002661), Dongjiang environmental protection (002672), Jiajia food (002650), Longquan stock (002671), Tengxin food (002702), Zhongke Jincai (002657), Xin electric machinery (002664), and Zhongke Jincai (002676) Gongda electroacoustic (002655), xuedilong (002658), Anzhong (002667), Huanghai machinery (002680), Baiyang (002696), maoshuo power (002660), Mengshi Technology (002684), Changliang Technology (300348)
it's time to prepare for the high delivery. For example, some varieties of Longquan stock and mengcao drought resistant (300355) have this condition both in terms of stock price and financial reporting conditions, and their performance is OK. If these stocks can release the high delivery plan earlier, the market funds will not lose the opportunity of speculation.
