IPFs (interplanetary file system) interstellar file system was set up by Juan Bennet in May 2014. It settled in Y combinator (successfully hatched airbnb, dorpbox, etc.) and got huge investment from YC. In 2015, Juan Bennett established protocol labs and released IPFs. At present, protocol labs have five independent projects: IPFs, filecoin, libp2p, ipld and multiformats. Most of its team members are from international famous universities, and Stanford University is the majority

usage scenarios of IPFs:

as a mounted global file system, mounted under IPFs and IPNs

as a mounted personal synchronization folder, version management and publishing are automatically performed, As an encrypted file or data sharing system, as the version package manager of all software, as the root file system of virtual machine, as the boot file system of VM (under the management program), as a database, applications can directly write data to Merkle DAG data model to obtain all versions, Buffer, as well as the allocation provided by IPFs

as a linked (and encrypted) communication platform

as a CDN for integrity checking of large files (without SSL)

as an encrypted CDN

on Web pages, As a web CDN

as a link, there will always be a new and eternal web

2. How blockchain can bring about a "revolution" in personal data protection
US media disclosed on the evening of 17 local time that Cambridge analysis, a British company deeply involved in the scandal of abusing personal privacy data, originally planned to launch a personal privacy data storage service and sell it in the form of encrypted currency through blockchain technology. The concept of personal information encryption and monetization is not new. The key to this idea is everyone's autonomy of personal information. Some people in the instry believe that blockchain technology may bring a "revolution" in personal data protection

in the era of big data, personal data is considered as precious as gold. Personal data leakage is worrying, but the vast majority of people can't be cut off from the Internet because of the fear of data collection. At present, enterprises, schools, hotels, social networking sites, etc., which are responsible for keeping personal information, often fail to take the responsibility. Experts believe that blockchain technology, as a "middleware" with encryption, trust, point-to-point, and difficult to tamper, is expected to solve this problem
the emergence of blockchain technology makes it possible for everyone to control their own personal data by transferring the control of personal data from Internet companies to users themselves. Through it, users' personal data can be associated with their personal digital ID card. Users can choose whether their digital ID card is anonymous, pseudonym or public. They can also access the blockchain application platform from any device anytime and anywhere to control their Internet personal data
for example, the information on the block chain of someone's ID number may be converted to a series of ciphertext, and the face image information is also encrypted. When he checked in at the hotel, he only sent the cipher ID number to the hotel through application. The hotel compares the information with the encrypted data on the block chain application, and does not need to know any real information of him, but as long as the encrypted data match the result, it can guarantee the check in.
at the same time, the development of big data and artificial intelligence needs a lot of user data resources. Users can selectively sell their personal data as cryptocurrency and receive certain returns. For example, if e-commerce needs user data to develop a new application, users can choose to sell their own shopping history data, but their address, account number and other information can still be kept confidential
in the field of gene sequencing, blockchain applications have begun to challenge the "way to make money" of traditional gene sequencing companies selling personal data
in recent years, gene sequencing services for ordinary people have been popular. Take "23 and me" chromosome biotechnology company in the United States as an example. Consumers only need less than $100 and a few mouthfuls of saliva to get family genetic information. If they pay another $80, they can get in-depth analysis of genetic health risks and other aspects based on the original data. However, the company was not satisfied with the revenue from sequencing services. It also sold millions of customer genetic data to pharmaceutical companies by classification and packaging. The Parkinson's disease data sold in early 2015 alone amounted to $60 million. Many similar biotech companies, while obtaining service income from consumers, resell the data of consumers to "earn double money"
in February this year, George church, a geneticist at Harvard University in the United States, founded "nebula gene", hoping to break this pattern through blockchain technology. The company plans to complete the whole genome sequencing at a price of less than US $1000. The cost is borne by the customers. In return, the customers can intuitively understand their own genetic information and corresponding disease risks, and also have the autonomy of sequencing data. The security of genetic information will be guaranteed by blockchain technology. At the same time, it will be encrypted and monetized, and it will be stored and sold according to customers' wishes
the company plans to launch a kind of "Xingyun coin" as the trading medium. Customers can exchange their genetic information into "Xingyun coin", and they can also use "Xingyun coin" to pay for their own sequencing expenses. Pharmaceutical companies can purchase "Xingyun coin" with traditional currency to obtain the genetic information data of ordinary people. The whole trading process is completed through the blockchain platform, Encryption is transparent and secure
chech said that after integrating the cost of sequencing, genetic information protection, data management, genome big data processing and other factors, blockchain technology allows more people to truly "own" their own genetic information.

3. First of all, the report quoted in the question is very wrong: bitcoin's original intention is not to break away from government regulation through anonymous payment, but to break away from government control and avoid inflation deliberately created by the irresponsible central government, which will cause great harm to the society. On the one hand, the German government recognizes that bitcoin trading can avoid tax losses. On the other hand, I guess the German people are happy to see bitcoin. From the German government's strong support for the euro, we can see that the German government is very inclined to strictly control the currency issuance: the control of the euro needs to be decided by the European Central Bank, rather than the countries in the euro area themselves. Bitcoin can be said to be the ultimate version of the euro. It is issued by various nodes, not by a central agency. In the European debt crisis, the control effect of the euro is obvious, and the Greek government must vigorously save public expenditure to avoid greater economic turmoil.
