Understanding Sentinel: A Comprehensive Overview

Sentinel’s dVPN employs a unique onchain query system that allows users to connect directly with exit nodes, bypassing intermediary servers. This system uses blockchain technology as a ledger for node querying. Nodes store and share their properties and connection instructions on the blockchain, and users generate a list of available nodes by querying this data from transactions on Sentinel’s dedicated dVPN zone. Authentication and identity are managed onchain, with potential failure points primarily at the consensus level. By contrast, traditional VPNs use centralized servers capable of logging interactions and revealing IP addresses.
