Statistical Program Of Bitcoin System Based On PC

Since the 1990s, Internet spread from universities and scientific research institutions to the homes of ordinary people gradually and rapidly. Application services based on the Internet fully reflects many different features and advantage, such as cross-regional service, low cost, high efficiency and personalized, from the traditional services. The financial industry is a traditional industry which earlier occurrence associated with the Internet. Early in the 1960s, Banking, securities and insurance industries began to use computers instead of manual operation. In the late 1990s, China’s banking industry have achieved a nationwide computerized banking network, interconnection and so on. Internet financial which rapidly develop, is the product of close integration of the financial sector and the Internet. Payment, settlement and financial intermediary is its representative.Online payment is the iuiciuimci of the lintiuet nuaiuce develolpinent. From the early electronic check and bank card to the moment, third-party payment and electronic money, from traditional forms of wired networks to wireless networks existed everywhere, individual means of payment has undergoned many changes. The scale of entire payment industry is huge. For example, the scale of China’s third-party payment increased from 3.2 trillion yuan to more than 10.9 trillion yuan during 2010 to 2012. Cutoff January 2013, the number of third party payment companies which has reached 223. Alipay, WeChat-Pay is the most famous representative of them. Develpoment of E-check, electronic checks and bank cards generally headed by traditional financial institutions, as a compare, electronic money more rely on Internet company.

Development of Bitcoin attracts more and more attention.November 1,2008, an anonymous user (or organization) who Self-proclaimed himself "Satoshi Nakamoto", published a paper, Bitcoin:A Peer-to-Peer Electronic Cash System, on cryptography discussion groups metzdowd.com. In this paper, Bitcoin system was first defined. Five years later, in March 2013, the total market value of Bitcoin has more than one billion US dollars. Many investors and researchers are attracted and involved in it.In 2012 September, Dorit Ron and Adi Shamir, Israeli researchers of the Weizmann Institute of Science, published a paper. In this paper, they analyzed many statistical properties of block chain. The two researchers take the data before May 13, 2012 of block chain as an example to describe the typical behavior of Bitcoin users. Based on those work, this paper mainly make the following work:First, an automated bitcoin data extraction program is designed. In this program, two databases MySQL and LevelDB are used together. It can import relevant information of block, trading and address into to databases and then do some statistical work about those data.Second, data of Bitcoin system during January 2009 to March 2015 was been statisticsed. These data contains blocks difficulty, file block size, numbers of transactions in a block, numbers of users, balance distribution, numbers of transactions that users participate, transaction amount, transaction costs and so on. Compared with other work, the statistics in there is more complete.Third, taking the block expansion problem as a clue, the data obtained are analyzed and compared, and the contradiction of the bitcoin system is discussed.
