Node Operators

Incentivized Testnet

The Nym protocol will allow operators to run mixnodes and gateways in the network and earn rewards. If you are interested in running a Nym node follow instructions on how to join Nym testnet Finney.

The Nym System

There currently exists no functioning protocol that can provide strong guarantees against the leakage and harvesting of metadata – for instance, data regarding the timing of communication, and the graph of who is communicating. Nym is an open-source, decentralized, permissionless and incentivized system that provides full-stack privacy, allowing developers to build applications that provide users with strong guarantees against metadata surveillance, at both the level of network traffic, and the level of authentication and payments.

How does Nym compare to VPNs?

The most popular network-level privacy solution currently is the VPN (virtual private network), which provides network-level protection via an encrypted tunnel between a user’s computer and one run by a VPN provider. VPNs are often misconfigured, however, and even when configured correctly, don’t offer real privacy or adequate resistance to censorship.

VPN providers can also fully observe all network traffic between users and the public internet, knowing exactly what services its users are accessing at a given time. The user must trust that the VPN provider is not using their information in a malicious manner or keeping logs.

The Nym mixnet is an anonymous overlay network that provides strong network-level anonymity, even in the face of powerful systems capable of passively monitoring the entire network. The mixnet is decentralized, with no trusted third parties, and so does not require a trusted provider like a VPN. More importantly, Nym provides superior privacy to VPNs and can support high-quality of service and low latency through incentives.
