How did virtual currency come up
after finding this kind of person, trade the currency to this person in the place where the virtual currency is used [for example, the forum currency is in the forum, and the game currency is in the game], and then use Taobao and other online stores to let them buy non physical goods, and their RMB will be transferred to your account
not all virtual currencies are bought with real money.
According to the white paper, the global borderless Libra coin has three cores: blockchain based, real asset guarantee and independent association governance. In other words, Libra coin is a "stable currency" guaranteed by the real asset reserve. Each Libra coin will have a basket of currencies or assets of corresponding value for trust endorsement, which is supervised by the founding members of Libra coin Association, and each founding member is responsible for running a verifier node. Facebook believes that there are still 1.7 billion alts in the world who are not exposed to the financial system and cannot enjoy formal financial services, and the current financial transaction costs are too high, so this pattern needs to be broken. According to its assumption, Libra is a stable currency and a super sovereign digital currency. By issuing "Libra coin", we will explore the establishment of a simple, borderless currency and financial infrastructure for billions of people
Protoco LBAs, also known as protocol lab, was founded in San Francisco Bay Area in May 2014 by Juan benet, a Stanford graate. Juan benet, born in California, USA, graated from Stanford University with a master's degree in computer science. He and his partners co founded Loki studios, a mobile ar game company, which was later acquired by Yahoo. He then moved to startx, a non-profit startup accelerator at Stanford University, where he started his career. In 2014, he founded the IPFs project and obtained investment from his alma mater. In January 2015, the official version of IPFs project was released
both IPFs and filecoin are projects built by protocol lab. IPFs is a point-to-point, versioned, content addressable hypermedia transport protocol, which is based on the traditional Internet Protocol HTTP. What it wants to build is a distributed Web 3.0. But IPFs is only an open source Internet underlying communication protocol, we can use it for free. At present, all IPFs nodes provide storage space, and they also need other nodes to help them store resources
in essence, IPFs transforms the original on-demand download of P2P software into long-term storage of resources. Long term storage requires quality of service assurance, otherwise no user is willing to store their valuable data or resource content that needs quality of service assurance in IPFs. Then, for a loose IPFs network, the random withdrawal of users, the uncertainty of network quality, the uncertainty of storage location, the uneven performance of hardware resources, the performance jitter of hardware resources, all these problems make IPFs unable to store resource storage with strong demand for quality of service, in other words, there is no way to use it in the commercial field
therefore, IPFs uses the incentive mechanism of filecoin to attract a group of professional storage service providers to provide more professional, secure and stable storage services. Filecoin is a decentralized storage network based on IPFs, the only incentive layer on IPFs, and a token issued based on blockchain technology. Miners in the filecoin network can obtain fil by providing storage and retrieval services for customers. On the contrary, customers can employ miners to store or distribute data by spending fil. Filecoin promotes the development of IPFs through economic incentive mechanism. At the same time, filecoin network also needs IPFs to provide ecological support for its market development. The more IPFs network is used, the greater the demand for filecoin is; The more miners filecoin has, the more support it has for IPFs network. So IPFs and filecoin form a symbiotic relationship. The birth of filecoin is to support the development of IPFs, and IPFs also needs filecoin to enrich its ecology. The more IPFs is used, the greater the demand for filecoin is; The more miners filecoin has, the more IPFs it supports<
