Technical Architecture (How SolanaVPN Works)
The architecture is layered, modular, and designed for privacy, scalability, and extensibility.
High-Level Layers
Client Layer (Browser + Local AI):
The user-facing browser integrates a local AI runtime (lightweight model) that performs query interpretation, context extraction, summarization, UI personalization, and temporary session memory handling.
Local AI uses encrypted checkpoints for federated updates and model enhancements.
Integrated non-custodial wallet signs microtransactions and interacts with Solana smart contracts.
Networking Layer (Decentralized VPN Node Mesh):
Node operators run relay software that exposes bandwidth/compute to the marketplace.
Traffic is routed through at least one (and optionally multiple) nodes chosen by the client; multi-hop routing and route obfuscation reduce correlation risk.
Node selection uses reputation, latency measurements, and economic bids.
Privacy & Cryptography Layer:
Zero-knowledge proofs validate correct node behavior without revealing content or metadata.
Homomorphic or encrypted inference techniques enable certain computations over encrypted data where needed.
Quantum-resistant algorithms (where feasible) protect long-term confidentiality.
Blockchain Layer (Solana Smart Contracts):
Staking contracts manage node bonds and slashing conditions.
Marketplace contracts handle bidding, session micropayments, and instant settlement.
DAO governance contracts manage proposals, treasury, and grant distribution.
AI Collaboration Layer (Federated & Secure Model Ops):
Federated learning aggregates model parameter updates in an encrypted/anonymous way to improve global models without collecting raw data.
zk-ML or verifiable ML techniques provide proofs that contributed model updates follow policy and do not leak information.
Important Technical Components
On-Device Local Intelligence
Lightweight models tailored for on-device inference (privacy-centric embeddings, query intent models, summarizers).
Session-based memory that is encrypted and ephemeral; optionally backed by user-owned encrypted cloud (user controls keys).
Local personalization pipelines avoid raw-data transmission.
Encrypted Session Memory & Ephemeral Context
Each session spawns a cryptographic memory pod which stores contextual vectors encrypted under a user key.
Memory pods allow personalization during the session but are destroyed or zeroed afterwards per user settings or default policy.
On-Chain Node Marketplace
Nodes advertise capability and stake $SVPN to signal commitment.
Users request a node or route; the smart contract creates a temporary session agreement and handles escrow of micropayments for the session until completion.
Reputation system aggregates on-chain performance metrics and community attestations.
Verification & Zero-Knowledge
ZK proofs confirm that nodes performed expected forwarding operations and did not log sensitive data.
zk-proofs also support anonymous, verifiable federated model updates so that contributors get credit without revealing who they are or what data they saw.
Scalability Considerations
Solana’s throughput enables high-frequency, low-cost micropayments for short-lived sessions.
Off-chain relays and state channels can be used for ultra-low-latency microtransactions when needed, with final settlement anchored on-chain.
