Frequently Asked Questions

General Questions

What is HOPR?

The HOPR network is an incentivized p2p network where nodes are relay points for transferring data between users. Data is encrypted and mixed in between nodes so the only people who can decrypt the data as well as know the source and destination are the actual source and destination. Users running nodes are incentivized to perform their duties correctly as the more successful packages are routed, the better the odds are for rewards, thus incentivising nodes to operate correctly.

Where can I find the yellowpaper?

Coming soon.

What is metadata privacy?

Metadata is information like who sent and received the data, when it was sent, and how much and what kind of data was involved. This is vital, because metadata can be used by malicious actors in all kinds of attacks, from hacks to unwanted user profiling.

What’s so special about HOPR?

What makes HOPR special is that people are rewarded for helping to relay data: when your node acts as a “hop” on the route data takes through the network, you’re rewarded via the HOPR token. This is important, because until now it was assumed that you can’t have incentives and full privacy at the same time: privacy requires anonymity, but with anonymity comes a lot of opportunity to try and cheat the system. HOPR’s payment layer solves this problem with what we call proof of relay.

What does HOPR help solve?

At HOPR we're building a mixnet which has way superior privacy guarantees and is still incentivized and decentralized. This means you will have more decentralization and incentives than e.g. Tor but at the same time we also have much more privacy than VPNs because no single node in the HOPR network can leak your browsing history. In fact with HOPR we need only one honest relay node to deliver a packet privately.

Where can I find stats about HOPR?

Is HOPR hiring?

Yes, We are always searching for new additions to add to our team https://hoprnet.jobbase.io

How can I contact the HOPR team?

You can contact us via email at contact[at]hoprnet.org

HOPR Protocol Questions

What is the HOPR Protocol?

The HOPR protocol allows users to run nodes which form a peer-to-peer privacy network. Data can be sent through the network without exposing the metadata — information like who sent and received the data, when it was sent, and how much and what kind of data was involved

What does Layer 0 mean?

HOPR is complementary to a lot of protocols like Matrix but HOPR also provides network-level privacy for blockchain application for truly private transactions — on-chain and off-chain, that’s why we call it a layer 0 protocol.

Is HOPR PoS or PoW?

HOPR is POS

What is Proof of Relay?

Proof of relay mechanism helps to separate out the messaging and payment layers, breaking any linkability between them. It turns out there’s a very useful overlap between what stakers expect and what mixnets need to remain anonymous

What is Cover Traffic?

Cover traffic - arbitrary data which helps boost metadata privacy for everyone in the network by obscuring usage levels.

When will HOPR launch the mainnet?

HOPR is launched on the Ethereum mainnet

HOPR Token Questions

Does HOPR have a token?

Yes, we launched our token in early March 2021.

Where can I buy the HOPR Token?

You can buy HOPR tokens from Uniswap / Ascendex

What is the utility of the HOPR Token?

"The HOPR token has three main uses:

  • Users can pay with HOPR tokens to send data through the HOPR network privately and securely.

  • Node runners can stake HOPR tokens in their nodes to be rewarded for relaying data. Node runners receive fees in HOPR for the data they help to relay, including a large number of tokens distributed in the form of cover traffic.

  • Finally, the HOPR token gives users voting power in the HOPR Association DAO "

What is the diference between xHOPR and HOPR?

xHOPR is a bridge of the HOPR token on the xDAI network.

Are the smart contract audited?

Yes the smart contracts are audited by Chain Security.

HOPR Staking Questions

Can HOPR token be staked?

Yes, currently we have a staking event

What hardware requirements are needed for running a node?

  • Node can be run on: PC / MAC / Raspberry Pi / Server

  • OS: macOS X / Linux OS (Ubuntu 16 and greater versions, Debian 10.x)

  • 2GB of RAM or greater.

  • Disk space at least 1GB.

  • x64 architecture CPU (any).

How to install a hoprd node, you will find here.

Are you rewarding node operators?

Node operators can stake HOPR tokens in their nodes to be rewarded for relaying data. Node runners receive fees in HOPR for the data they help to relay, including a large number of tokens distributed in the form of cover traffic.
