HOPR is a decentralized, incentivized mixnet that aims to bring true privacy to web3. It allows for the transmission of any kind of data without revealing the metadata. HOPR does not have its own blockchain, but node runners may receive HOPR tokens as compensation on Gnosis Chain and Ethereum mainnet. Developers can build their own decentralized applications (dApps) on top of HOPR, giving users control over their online and personal data. The HOPR token launched in February 2021, and all proceeds from the launch are controlled by the HOPR DAO, a decentralized autonomous organization.

HOPR works by providing scalable transport level privacy, enabling the creation of truly private, applications for web3. It uses a proof-of-relay mechanism, a cryptographic system that rewards node runners only after they have successfully relayed data, while preserving their privacy. Node runners are compensated with HOPR tokens only after completing their mixing and relay duties. The HOPR protocol is designed such that no one but the sender can know the details of their data and its route through the HOPR mixnet.

HOPR can be used in a variety of ways to enhance privacy in the digital world. For instance, it can be used to browse information from websites without being tracked by ISPs or third-party providers. It can also be used to send blockchain transactions without leaking metadata to miners or other relayers. Furthermore, HOPR can be used to create peer-to-peer applications that require private communication, such as gaming and online chats. It can also be used to proxy traffic via a SOCKS-like interface that forwards traffic via the HOPR network.

HOPR was founded by Sebastian Bürgel, a graduate of ETH Zurich with a degree in information technologies and electrical engineering. Bürgel co-founded SONECT, an ATM as-a-service provider company, and served as the chief technology officer for SONECT until 2017. He also served as CTO at Validity Labs, providing education-related solutions via blockchain technology. In 2020, Bürgel left Validity Labs to start HOPR. The HOPR token launched in February 2021, and all proceeds from the launch are controlled by the HOPR DAO. The development of the HOPR protocol is overseen by the HOPR Association, a privately funded organization separate from the HOPR DAO.
