How Orchid delivers digital privacy

The Orchid network enables a decentralized virtual private network (VPN), allowing users to buy bandwidth from a global pool of service providers.

To do this, Orchid uses a new digital currency called OXT, a new VPN protocol for incentivized bandwidth proxying, and smart-contracts with algorithmic advertising and payment functions. Orchid's users connect to bandwidth sellers using a provider directory, and they pay using probabilistic nanopayments so Ethereum transaction fees on packets are acceptably low.

The Orchid app

Orchid is a VPN client, VPN service powered by our own digital currency, and advanced networking tool designed to give you insight and control over your phone's network connection. The Orchid app goes past the basic functionality offered by most VPN clients, with features such as the ability to run traffic through multiple nodes in a multi-hop route. The Orchid client is accessible via iOS (beta testing only), Android, macOS, Linux, and (soon) Windows.

The Orchid digital currency (OXT)

OXT’s primary and fundamental purpose is to allow users to purchase digital privacy services from the Orchid network.

The OXT digital currency provides value in the Orchid network in a number of ways:

  • A Bandwidth Provider - Anyone can operate an Orchid Node, but must first stake OXT, with the more OXT that is staked, the greater the chances of reward in the Network.
  • A Bandwidth User- For the first time, users can pay-on-the-fly for a private, secure internet connection. To power up the client, a user installs the Orchid VPN, adds OXT to a wallet, and then can access the internet through a user-chosen path to ensure a secure connection anywhere in the world. Users only pay for the bandwidth they consume.

The bandwidth marketplace is peer-to-peer and run in a completely decentralized manner without reliance on any central party. The primary reasons for this new digital currency OXT are:

  1. To have a digital currency that is specifically tied to consumption of bandwidth on the Orchid network
  2. To align operator incentives towards the benefit of the Orchid Network.

Accordingly, in addition to facilitating bandwidth transactions on the Network, the Orchid digital currency is used to prove a stake within the Orchid network that demonstrates a commitment by bandwidth providers, as well as to mitigate certain risks.

The Orchid Protocol

The Orchid software is designed to use a custom VPN protocol, similar in scope to OpenVPN or WireGuard. The Orchid protocol is designed for high-performance networking and runs on top of WebRTC, a common web standard, widely used to transmit video and audio from inside browsers. Our protocol allows users to request access to remote network resources and pay for these resources using OXT via the Orchid nanopayments system.

Orchid Nanopayments

Orchid uses a new probabilistic nanopayment system to scale payment throughput.

This nanopayment system is the foundation of the Orchid peer to peer bandwidth marketplace where clients pay Node operators OXT “tickets” for proxy bandwidth. The system is designed to lower the transaction fees on small payments by amortizing transaction fees across many transactions and even across multiple parties.

Service providers on Orchid run software similar to a typical VPN daemon for protocols such as OpenVPN, but which speaks the Orchid protocol.

Orchid nodes maintain registration information in a stake registry and provider directory on Ethereum. The stake registry is optimized for enabling the Orchid app to automatically discover random servers in a decentralized environment, while the provider directory allows Orchid nodes to register metadata such as geolocation or additional services offered.

A provider stakes some number of OXT to create a stake deposit.

  • Anyone can stake OXT on nodes using the smart contract.
  • Clients select new nodes in proportion to their relative OXT deposit size.
  • Larger stake deposits thus lead to proportionally more users, bandwidth, and revenue.
  • If the node is already at max bandwidth capacity additional stake is effectively wasted.

Once digital currency has been locked into a stake deposit it can be used immediately for bandwidth provisioning. If the provider wants to withdraw digital currency from the staking contract, they have to start an ‘unlocking’ process period, which involves a three month cooldown where their funds cannot be used as a stake deposit or transferred elsewhere by the provider.

Whatever the amount of value that is exchanged in the Orchid ecosystem, a given seller’s relative stake amount, as a percentage of the total stake, provides them that same percentage of user traffic and dealflow. Assuming typical and honest selling behavior (no users drop them for bad service) this dealflow will translate into a similar portion of the total revenue. The staking decisions of sellers is left to their own choices.
