Five-Layer Privacy Stack · FCMP++ · IDAG Consensus · DSP Transactions

The first blockchain to ship a production FCMP++ implementation — full-chain membership proofs using dual curve trees (secp256k1 + Ed25519) that provide whole-pool anonymity sets. Innova combines a five-layer privacy stack with a hybrid PoW/PoS consensus, IDAG block DAG ordering, and Dynamic Selective Privacy (DSP) transactions — making it the first chain to unify zero-knowledge proofs, DAG consensus, and Proof-of-Work/Proof-of-Stake in a single protocol.

Core Technology

Four foundational innovations that position Innova at the intersection of privacy, consensus, and zero-knowledge cryptography.

DSP

Dynamic Selective Privacy

Eight configurable privacy modes per transaction — from fully transparent to maximum shielded. DSP lets users choose the exact level of privacy for each transaction, enabling regulatory compliance where needed while maintaining full anonymity by default.

Mode 0: Fully transparent (addresses + amounts visible)

Mode 1–3: Partial shielding (amount hidden OR address hidden)

Mode 4–5: Lelantus + Pedersen (sender ambiguity + hidden values)

Mode 6: FCMP++ full-chain membership proof (whole-pool anon set)

Mode 7: Maximum — FCMP++ + Silent Shielding + Dandelion++ relay

Per-transaction selection — no wallet-wide commitment required

Formalized in IIP-0004 with backward compatibility

FCMP++

Full-Chain Membership Proofs

Innova is the first blockchain to ship a production FCMP++ implementation. Full-Chain Membership Proofs use dual curve trees (secp256k1 + Ed25519) to prove a transaction input belongs to the set of ALL unspent outputs — without revealing which one. This provides a whole-pool anonymity set rather than a fixed ring size.

Dual curve tree: secp256k1 + Ed25519 for cross-curve verification

Whole-pool anonymity — every UTXO is a potential decoy

Deterministic DAG-ordered epoch commits for IDAG compatibility

Compact proof size regardless of UTXO set size

Eliminates ring signature limitations (fixed decoy set)

Contributed upstream — advancing the state of privacy across the ecosystem

IDAG

Incremental DAG Consensus

IDAG migrates Innova from a linear blockchain to a high-throughput block DAG — the first DAG to combine DAGKNIGHT adaptive ordering, PoS finality, and full zero-knowledge privacy. Four-phase rollout from GHOSTDAG block ordering through adaptive DAGKNIGHT k-inference to ⅔-stake hard finality.

GHOSTDAG ordering (Phase 1 — live)

DAGKNIGHT adaptive k-parameter via inference (Phase 2 — upcoming)

Sub-second block intervals with adaptive block sizing

Three-tier finality: Tentative → Soft → Hard (configurable stake thresholds)

POEM entropy weighting for fork resolution

Epoch-anchored FCMP++ membership proofs — first ZK privacy in a DAG

NullStake

Zero-Knowledge Private Staking

NullStake enables fully private Proof-of-Stake participation — stakers earn rewards without revealing their balance, identity, or staking activity. Three protocol versions progressively strengthen the ZK guarantees while adding auditability via viewing keys.

V1: Anonymous staking via zero-knowledge proofs — prove stake without revealing which UTXO

V2: Enhanced proof system with compact verification and optional viewing-key auditability

V3: Optimized ZK staking circuits with tighter proof bounds

Viewing keys allow optional third-party auditability without breaking privacy

Staking rewards distributed without linking to staker identity

Formalized across IIP-0009 (V1) and IIP-0010 (V2)

NYX

Encrypted Messaging System

Nyx is a fully decentralized encrypted messaging protocol built into the Innova blockchain. Messages relay through the P2P network via Dandelion++ stem routing — no central server, no metadata leakage, no IP correlation. Sender verification uses FCMP++ membership proofs so message origin is cryptographically anonymous.

Live Now

Encryption: AES-256-CBC + HMAC-SHA256 via SMSG protocol

Key Exchange: ECDH secp256k1

Relay: Dandelion++ stem routing with configurable parameters

Verification: FCMP++ membership proofs

Decentralized — no central server, messages relay through the P2P network

Layer 1: Post-quantum key encapsulation (NIST standard)

Layer 2: Authenticated stream cipher

Layer 3: Authenticated block cipher with ECDH key derivation

Group chats: tree-based key agreement (up to 16 participants)

File transfers: encrypted decentralized storage via Hyperfile/IPFS

Auto key rotation per session

IDNS

Blockchain-Native Domain Name System

IDNS anchors DNS records directly on the Innova blockchain — eliminating centralized registrars, ICANN governance, and single points of failure. Domain ownership is proven by private key, records are immutable once committed, and resolution is trustless via the P2P network. Unlike ENS or Unstoppable Domains, IDNS supports the full range of standard DNS record types.

IPv4 address mapping

AAAA

IPv6 address mapping

Nameserver delegation

PTR

Reverse DNS lookup

Mail exchange routing

TXT
