HOPR's founding team: Robert Kiel, Sebastian Bürgel and Rik Krieger.
HOPR, a data privacy startup, announced the release of a public incentivized testnet for its mixnet on xDai, an Ethereum sidechain.
A mix network or “mixnet” (taking its name from the proxy servers it employs, called “mixes”) obscures the metadata left behind when data passes through a network, which can be observed on most networks by state-level adversaries.
Nicknamed HOPR Säntis (after a Swiss mountain) and running on the xDai chain, the firm says the testnet provides “fast transactions secured by proof-of-stake, while eliminating the high Ethereum transaction fees.” Transaction costs on the xDai network are lower than on the Ethereum mainnet.
Participants in the program will earn ERC-20 HOPR tokens for running a node. These tokens will be distributed when the HOPR mainnet launches in late 2020.
“We want to get people to run a node ahead of our mainnet launch later this year and already earn tokens for that,” HOPR lead Sebastian Bürgel said in an email to CoinDesk.
The incentivized testnet is also a chance to get feedback on the mixnet, detect bugs and generally take the network to the next level with a second round of feedback, following the firm’s initial public testnet this summer, according to Bürgel.
While HOPR sells its own hardware node version (at $440), a HOPR node can also be run on devices that run Windows, macOS and Linux.
The reason for using hardware rather than the cloud, said Bürgel, is that it’s better for decentralization as it doesn’t rely on cloud infrastructure.
Privacy is widely seen as a necessary feature for the widespread adoption of blockchain technology. Ethereum is taking steps in that direction.
What to know:
Vitalik Buterin outlined three near-term Ethereum upgrades aimed at making privacy a native feature of the network rather than relying on third-party tools.
Account abstraction and FOCIL are designed to make private transactions harder to censor by changing how accounts work and how validators must include transactions in blocks.
