Decentralized Virtual Private Network (DPN) is an advanced evolution of traditional VPN technology. It uses decentralized blockchain technology or peer-to-peer networks to provide secure and private communication over the internet.
Decentralized Virtual Private Network (DPN) employs advanced technical architectures and protocols to deliver secure, private, and decentralized internet communication.
Key Underline Technology Architecture –
Distributed Hash Table (DHT)
- Used to locate and store data within the decentralized network.
- Ensures fast and reliable lookup of available nodes and their resources.
Onion Routing
- Data is encrypted in layers, with each node peeling off one layer before passing it to the next.
- This prevents any single node from knowing the complete path of the data.
Session Establishment
- Public Key Infrastructure (PKI): Used to establish secure sessions between users and nodes.
- Ephemeral Keys: Session keys are short-lived, reducing the risk of long-term exposure if compromised.
Bandwidth Marketplace
- Nodes register their bandwidth availability on the network.
- Users can “purchase” bandwidth using native tokens or cryptocurrencies.
Zero-Knowledge Proofs
- Enable nodes to prove actions (e.g., handling a specific transaction) without revealing sensitive data.
- Protects user anonymity while ensuring accountability.
Anti-Sybil Measures
- Prevent malicious entities from creating numerous fake nodes to disrupt the network.
- Typically implemented using stake-based verification or proof-of-work mechanisms.
Distributed Ledger Technology (DLT)
- Maintains an immutable record of transactions, payments, and node participation.
- Ensures transparency without compromising user data privacy.
Utility Tokens: Facilitate payments for services like bandwidth and incentivize node operators.
Incentivization Mechanisms:
- Users earn tokens for contributing bandwidth and computational resources.
- Smart contracts automate payments and ensure fair compensation.
DPN Protocols
- Sentinel: Uses a bandwidth marketplace with blockchain technology for payments.
- Mysterium: Focuses on a decentralized VPN marketplace with robust privacy features.
- Orchid: Implements multi-hop routing and a staking mechanism for secure DPN operations.
- Deeper Network: Combines hardware and software solutions for enhanced DPN performance.
