As digitalization penetrates into every corner of life, the boundaries between public space and private space are increasingly blurred. Does the ubiquitous data information provide convenience for people, or sacrifice the original personal privacy rights?

Protecting data privacy is urgentThere have been many incidents about the leakage of private data.In 2016, Uber
The cyber attack resulted in the leakage of user data. The leaked information included the user's full name, email address and phone number.In 2018, the Facebook "data gate" incident was exposed, also inIn 2018, Huazhu Group
The user data of its chain hotels is suspected to have been leaked, and some sellers packaged and sold about 500 million pieces of data.In an environment where data leakage incidents emerge in an endless stream, topics related to privacy protection have been put on the agenda.The European Union's General Data Protection Regulation (GDPR) came into force in 2018
Representative laws and regulations such as California Consumer Privacy Act (CCPA) in California, my country’s Data Security Law (draft), and Personal Information Protection Law (draft) have been promulgated, which strictly require proper handling of data during the use of data.privacy protectionprivacy protection
, such as not allowing data to leave the local area, not allowing unauthorized use of personal data, and so on."Metadata" still cannot be fully protected.

Web 3.0 Metadata Privacy EraThe key to protecting privacy is to encrypt data, but protecting data alone is not enough.Web 3.0 The New Digital Era, need to cause theattention, because metadata is one of the key and basic links of decentralized financial transactions.
metadatametadata
It is a series of data generated by performing operations on the Internet, such as visiting a website, using an application, or sending a message.metadata recordsInformation such as who sent the data (in the form of IP addresses), where they were sent (another IP), at what time, and how much data was sent. In short, this is
"Data about data."Although metadata itself does not carry much information, every online interaction of users will generate dozens of pieces of metadata, and almost all of these data are public or easy to track. If someone collects enough metadata, even with end-to-end network encryption, it will be possible to passsplicing to clearly understand

, note where the envelope went, what size it was, and when it was mailed.Over time, a database of the above information can be built and tracked, and all operations
You don't even need to open the envelope.Taking this a step further, if you can see which stores a user is shopping at, which apps they are using, and whom they are messaging, you don't actually need to know the full details of your messages or purchases to be able to
Infer additional personal information.Taking a whole new approach to data transfer, that's what HOPR is doing.

What is HOPR?HOPR is a program that allows users to runA protocol for peer-to-peer privacy network nodes
, which can send data over the wire without exposing metadata. Metadata can be described as the object that sends and receives data, the time when data is sent, the amount of data sent, the address where data is sent, and so on. HOPR can ensure the privacy of the sender and receiver while ensuring the encryption of the information content.HOPR provides a way for people, companies and devices toExchange information online in complete privacy
In a way, the privacy of users who use HOPR or applications and services running on the HOPR platform for communication and transaction processing will be protected, and no one will be able to obtain the data that users are sharing, who is sending or receiving data and even how much. Privacy information such as data being sent.on the other hand. HOPR isFully decentralized protocol
, has high transparency and credibility, and does not have to rely on third parties, which also means that data will not be locked in a service, and at the same time control the data.HOPR is run by users, for users.
Anyone can help maintain the HOPR network by relaying data through a HOPR node, either on a computer or as a standalone device that plugs into a router.HOPR provides goodIncentives,Source: Medium

HOPR two major technical frameworks
HOPR provides privacy by forwarding messages through different relay nodes connected to the network. These messages use the Sphinx package format to avoid leaking any data about their content, sender or receiver.From the perspective of technical architecture, HOPR is divided intoMessaging Layer and Payment Layer
And the network layer, the messaging layer is used for information and node encryption, and the payment layer is used for node rewards.
messaging layermessaging layer
Responsible for handling data transmission throughout the HOPR network, data packets are "actively" mixed at each information delivery stage through the network, and HOPR's proof-of-relay mechanism ensures that data reaches its destination without others knowing the sender and receiver The full path taken by the identity or data of the .Messages transmitted using HOPR are embedded in the SPHINX packet format, provablyimage description

summary
summary
Today, DeFi has become an indispensable and important part of the encryption system, and finance, data, and decentralized networks need a new privacy foundation. HOPR is working to build a Layer0 privacy infrastructure for Web 3.0, so that it can transmit information safely and reliably, ensuring that everyone can control their privacy, data and identity at all times.
