Development Roadmap
PHASE 0 — DONE
Foundation & Architecture Design
- XChaCha20-Poly1305 + Double Ratchet + Argon2id crypto stack defined
- StealthX platform alignment (shared lazysodium stack with SecureCall + Chameleon)
- IFR Token integration design (same contract: 0x769928aB…)
- Threat model and security boundaries documented
- 3-layer architecture: Kaspa identity + ephemeral relay + device crypto
PHASE 1 — ACTIVE · Q2 2026
Android App — Core Messaging Pre-Alpha
- Local E2E encrypted messaging (XChaCha20 + Double Ratchet)
- QR + NFC key exchange (Ed25519-signed bundles)
- X25519 key management via Android Keystore
- Room + SQLCipher local message storage
- STEALTH-DELETE emergency wipe
- IFR Token tier gating (FREE / PRO / ELITE)
- StealthX dark design system
PHASE 2 — Q3 2026
Kaspa Identity Layer + Relay Decentralization
- Public key anchoring on Kaspa BlockDAG (one tx = permanent identity)
- Contact discovery by Kaspa address
- Ephemeral relay node protocol (SMP-style unidirectional queues)
- KAS micropayment incentives for relay operators
- Tor Hidden Services for all Relay Nodes (standard — .onion addresses)
- Kaspa Node-Registry: X25519 + .onion on-chain via OP_RETURN
- 2-hop Onion Routing for Pro tier (2 hops), Elite tier (3 hops)
PHASE 3 — Q4 2026
Group Messaging + Advanced Privacy
- Encrypted group chats with per-member key derivation
- XFTP-style encrypted file transfer (chunked, deleted after delivery)
- 3-hop Onion Routing (Elite tier) — maximum anonymity
- Cover Traffic — dummy packets against traffic analysis (Global Passive Adversary protection)
- Pluggable Transports: obfs4/Snowflake for censored regions
- Kaspa relay node network public launch
- iOS client design (shared Rust crypto core planned)
PHASE 4 — 2027
StealthX Layer 1 Migration + Public Release
- Full migration to StealthX Layer 1 protocol
- External security audit (Trail of Bits)
- Nym Mixnet Integration (research / optional — timing-resistant privacy)
- Sybil protection via KAS-Deposit for node operators
- F-Droid submission (GPL-3.0, reproducible build)
- Google Play Store release
- iOS client (App Store)
- IFR BuilderRegistry on-chain registration
- stealthx.tech full SecureChat integration
