Key Differences:

	U2DPN	VPN
Maintenance	Managed by the community, fully decentralized	Managed by a service provider
Server	Validator nodes and Contributor nodes are operated by individuals setting up a fully decentralized network	The centralized server network owned by single company
Speed	Depends on the quality of the network and the proximity of distributed nodes managed by individuals. There is requirement of minimum speed to join the network as Contributor nodes	Depends on the capacity of the server network and the proximity of servers managed by the service provider
Encryption	Yes	Yes

Unicorn Ultra DPN Subnet Infrastructure Overview

Understanding the flow

• A Client request for DPN service in DPN Subnet

• DPN Subnet introduces a Contributor Node (DPN Provider)

• Client and Contributor Node handshake a Private Channel to share the bandwidth and also open a Reporting Channel to report the metrics (fee, duration and measure the bandwidth shared…) for DPN Validator

• DPN Validators verify the session and process the payment after a session is closed.

• DPN Validators submit proof of activities to U2U Mainnet
