🖥️Oxen Service Nodes

Oxen Service Nodes provide the underlying support for the Oxen Network

The Oxen Network has transitioned to the Session Network. More information here.

Oxen’s networking functionality, scalability, and decentralisation tech stack is powered by a set of incentivised nodes called Oxen Service Nodes. To operate a service node, an operator time-locks 15,000 $OXEN, and the service node begins providing a minimum level of bandwidth and storage to the network. In return for their services, service node operators receive a portion of the block reward from each block mined on the Oxen blockchain.

The resulting network benefits from market-based resistance to Sybil attacks, addressing a range of problems with existing onion routers and privacy-centric services. This resistance is based on supply and demand interactions which help prevent single actors from possessing a large enough stake in Oxen to have a significant negative impact on the second-layer privacy services Oxen provides. DASH first theorised that cryptoeconomics can provide a network with properties of Sybil attack resistance. In our case, as an attacker accumulates $OXEN, the circulating supply decreases, in turn applying demand-side pressure and driving the price of $OXEN up. This effect spirals, making it increasingly costly for additional $OXEN to be purchased and thus making an attack prohibitively expensive.

To maintain this protection, Oxen encourages active suppression of the circulating supply. In particular, the emissions curve and staking requirement have been designed to ensure enough circulating supply is locked (and reasonable rewards are provided to operators) to ensure Sybil attack resistance.

Service Node activities

An Oxen Service Node becomes active on the network when its owner stakes (locks up) the required amount of $OXEN, which submits a registration transaction. Once accepted by the network, the service node becomes eligible to receive block rewards. Multiple participants can stake to a single service node, combining their smaller stakes to meet the 15,000 $OXEN staking requirement. The block reward can be automatically distributed among the participants in a ratio proportional to each participant's staking contribution.

Once active on the network, Oxen Service Nodes are required to:

• Monitor other service nodes and vote on their performance

• Create new blocks on the Oxen blockchain (see Pulse)

• Receive, temporarily store, and forward encrypted messages (see Session)

• Participate in quorums to enable instant $OXEN transactions (see Blink)

• Route end-user internet traffic (see Lokinet)
