The Privacy Layer of Solana • Version 1.0.0
Moonware OS introduces native privacy to the Solana ecosystem through scalable, efficient, and secure cryptographic design. It empowers users with financial privacy while remaining transparent, auditable, and non-custodial.
Complete technical specification covering architecture, cryptographic primitives, privacy guarantees, and implementation details.
01. Overview
Moonware OS is the privacy layer of Solana. It is a modular system that makes privacy a native feature of the blockchain—from stealth transactions to encrypted communication, enabling users to stay invisible while staying connected.
"Privacy is not about hiding. It is about protecting what matters."

02. Mission & Vision
We believe privacy is not a privilege but a right. Moonware OS exists to restore digital freedom by building privacy, anonymity, and control into Solana. Our tools let you transact, communicate, and build without exposure or surveillance.
Privacy by default, transparency by choice.
Cryptography replaces trust.
Decentralization is defense.
Moonware OS was created to make privacy simple, accessible, and built into the core of blockchain. Our vision is a world where every digital interaction can be private by default—as natural as sending a message or making a payment.
03. Architecture
Moonware OS is built as a set of independent yet connected modules. Each brings a layer of privacy to the Solana ecosystem. Use them individually or as one integrated privacy layer.
MoonOS
Ephemeral Privacy Runtime
Disposable session manager that isolates device fingerprints, IP addresses, and wallet keys within temporary execution contexts. Each session self-destructs on completion, leaving zero persistent state.
Tx ShadowNet
Multi-Hop Relay Mesh
Distributed relay network fragmenting transaction paths across independent nodes. Path selection algorithms optimize for unlinkability while maintaining sub-second finality.
ID Obfuscation
One-Time Identity Layer
Generates ephemeral Moon IDs and stealth addresses for every interaction. Past activity remains cryptographically unlinkable from future operations through rotating key material.
DarkRelay Messaging
Encrypted Communication Channel
Hybrid messaging architecture storing encrypted payloads off-chain while anchoring commitments on-chain. Enables selective disclosure without exposing message content.
MoonPay
Private Payment Pipeline
One-time payment link generator creating unique settlement paths. Automatically sweeps funds through stealth addresses with ShadowNet routing.
MoonRoute
Stealth Swap Engine
Private DeFi execution layer pairing stealth addresses with hidden liquidity routing. Settlement occurs through unlinkable transaction pathways.
MoonMask
Identity Shield
Persona management layer decoupling on-chain activity from real-world identity. Rotates behavioral signatures to prevent profiling and correlation.
04. Privacy-First Operating Flow
Every user action passes through five cryptographic stages. Each stage adds a layer of anonymity, culminating in zero-metadata output.
User Action
Transaction or message initiated
ID Obfuscation
One-time alias generated
ShadowNet Routing
Multi-hop relay path selected
Encryption
HPKE + ZK + MPC applied
Zero Metadata
Complete privacy achieved
05. Anatomy of the Void
Deep dive into the technical implementation: smart contracts, zero-knowledge circuits, backend infrastructure, and transaction lifecycle.
Smart Contracts
Rust • Solana BPF- ▸Accept deposit commitments and manage Merkle tree of valid notes
- ▸Validate zero-knowledge proofs during withdrawal operations
- ▸Prevent double-spending via nullifier tracking and verification
- ▸Token support: SOL native with SPL token expansion planned
Zero-Knowledge Proof System
zk-SNARKsUses zk-SNARKs to prove deposit ownership without revealing which specific deposit. Compatible with Groth16, PLONK, and Halo2 proof systems.
Proof Generation
Handled off-chain in client browser. User computes witness and generates proof locally. No server-side key material.
On-Chain Verifier
Smart contract verifies proof validity in < 10ms. Accepts proof to approve withdrawal without revealing deposit linkage.
Backend Indexer
Node.js • GraphQL- ▸Ingests on-chain data: deposits, nullifiers, withdrawal events
- ▸Stores indexed data in PostgreSQL for fast queries
- ▸Powers analytics dashboards and transaction tracking
- ▸GraphQL API for real-time privacy metrics and relay status
Frontend Interface
React • Web3.js- ▸Built with React and @solana/web3.js for seamless wallet integration
- ▸Intuitive UI for depositing, withdrawing, and generating zk-proofs
- ▸Connects to Solana wallets: Phantom, Solflare, Backpack
- ▸Fully responsive: optimized for mobile and desktop experiences
From Commit to Silence: Transaction Lifecycle
Deposit Phase
User generates secret pair: (nullifier, secret)
Computes commitment: C = H(nullifier, secret)
Sends commitment C to Moonware smart contract
Contract inserts C into Merkle tree of valid notes
Withdrawal Phase
User generates zk-proof demonstrating:
- • Knowledge of
(nullifier, secret)linked to Merkle root - • That the nullifier has not been previously used
- • Membership in the valid commitment set
Sends to contract:
- → zk-proof (PLONK/Groth16)
- → recipient address (can be new stealth address)
- → nullifier (marks note as spent)
Contract verifies proof and nullifier, then transfers funds to recipient

06. Cryptography
Moonware OS is powered by modern cryptographic primitives. Privacy is the default setting. Transparency is a choice.
Stealth Addresses
ECDH Key Exchange
One-time payment addresses computed via elliptic-curve Diffie-Hellman
HPKE Encryption
RFC 9180
Hybrid public-key encryption for non-interactive message sealing
PLONK ZK Proofs
Universal SNARKs
Zero-knowledge proofs for transaction validity without revealing inputs
Multi-Party Computation
Threshold Cryptography
Distributed secret management via Shamir secret sharing
07. Privacy by Design
Guiding principles that shape Moonware's architecture, user experience, and cryptographic guarantees.
Privacy by Default
Zero configuration required
Every transaction, message, and interaction defaults to maximum anonymity. Users never toggle privacy settings—protection is automatic and omnipresent.
Transparency by Choice
Selective disclosure mechanisms
Users control what they reveal through zero-knowledge proofs. Can prove compliance, fund origin, or identity without exposing full transaction history.
Technology over Trust
Cryptographic guarantees
Privacy depends on mathematics, not institutional promises. ECDH, HPKE, PLONK, and MPC provide verifiable security properties.
Decentralization as Defense
No single point of failure
ShadowNet relays and MPC nodes distribute trust across global mesh. Compromise of individual components does not breach system-wide privacy.
Simple and Usable
Performance matches Solana speed
Sub-second finality with 65,000 TPS throughput. Privacy layer adds < 400ms latency. User experience indistinguishable from standard Solana interactions.
Open and Verifiable
Auditable implementation
Critical components open-sourced for community review. Cryptographic proofs are publicly verifiable. No backdoors, no hidden telemetry.
Freedom for Everyone
Individual sovereignty
Built for journalists, whistleblowers, activists, and everyday users. Privacy is a right, not a privilege reserved for institutions.
08. Getting Started
Quick Start Guide
Connect Solana Wallet
Use Phantom, Solflare, or any Solana-compatible wallet. Moonware detects your wallet and initializes privacy layer automatically.
Enable MoonOS Sessions
Activate ephemeral runtime that masks device fingerprints and wallet metadata. Each session auto-destructs after use.
Create Private Payment Links
Generate MoonPay links with one-time stealth addresses. Recipients receive funds anonymously with automatic sweep.
Route via ShadowNet
All transactions fragment across 3-7 relay hops. Origin and destination remain hidden from network observers.
Encrypted Messaging
Send HPKE-encrypted messages through DarkRelay. Only intended recipients can decrypt. Forward secrecy guaranteed.
Verify Privacy Status
Dashboard shows real-time anonymity metrics: relay count, metadata status, and unlinkability score.
