Tribus Algo PoW/PoS Hybrid Cryptocurrency
Innova [INN] is an energy-efficient Proof-of-Work (Tribus algorithm, created by carsenk) and Proof-of-Stake hybrid cryptocurrency with an optional privacy stack.
Ticker: INN
The privacy stack (shielded pool, FCMP++, NullSend, NullStake, silent shielding) activates with the v5 hardfork. The legacy prototype transaction versions (2000–2007) are rejected on public networks; the version-2008 envelope that replaces them activates at Boundary B, height 8,151,540 on mainnet. Until then, transparent transactions are the public-network path. See Privacy & Protocol Innovations for the per-feature status.

- Hybrid PoW/PoS Collateral Nodes
- Stealth addresses — retired; existing ones keep working and their funds stay spendable, but new ones are not issued. Superseded by IV5 shielded addresses, which hide the amount and sender as well as the recipient
- Ring signatures (legacy tx version 1000) — rejected from height 0 on testnet/regtest; on mainnet valid until the v5 first gate, height 8,150,040 (IIP-0003)
- Native Optional Tor Onion Node (-nativetor=1)
- Encrypted Messaging (SecureMsg) — optional, disabled by default; enable with
smsg=1 - Multi-Signature Addresses & TXs
- Atomic Swaps using UTXOs (BIP65 CLTV)
- SLIP-44 coin type 116 registered, so BIP39/BIP44 wallets can derive Innova keys;
innovadhas its own 24-word recovery phrase (z_exportphrase/z_importphrase) covering the shielded seed and HD-derived transparent keys - Proof of Data (Image/Data Timestamping)

What the v5 fork activates on public networks. Each is a height-gated flag day on the mainnet ladder (see IIP table for effective heights); none has activated on mainnet yet.
- IDAG — DAG block-ordering layer for high throughput (~1 second post-DAG)
- Epoch finality — 300-block epochs finalized by a participation quorum of transparent and anonymous note votes (no committee)
- POEM entropy weighting
- IDNS name reset
- Cold staking (P2CS)
Already live on mainnet today, ungated: Dandelion++ transaction-origin privacy (relay policy, on by default), silent payments, stealth addresses, Proof of Data timestamping, and the IDNS name-value system.
The legacy envelopes (transaction versions 2000–2007) are rejected on mainnet
and testnet at every height by IsLegacyPrivacyPolicyDisabled() (main.h). The
unified version-2008 envelope that replaces them activates at Boundary B:
height 8,151,540 on mainnet, the same height as Boundary A
(FORK_HEIGHT_BOUNDARY_B, main.h).
- Shielded pool — Pedersen commitments, Bulletproofs, and Lelantus-style proofs
- FCMP++ full-chain membership proofs (curve-tree + inner-product argument)
- NullSend — confidential CoinJoin-style transaction mixing
- NullStake — zero-knowledge private staking (V1/V2/V3)
- Silent shielding (the silent-payment/shielded-pool composition)
- Dynamic Selective Privacy — the 3-bit disclosure mask
See docs/architecture/ for the consensus and privacy design docs; PRIVACY.md and CONSENSUS.md both carry the same status caveat.
Innova includes an optional off-chain encrypted messaging channel, disabled by
default. Enable it with smsg=1 in innova.conf (or -smsg on the command
line) and restart; -nosmsg forces it off and overrides -smsg.
When enabled, each message is encrypted to the recipient's public key using ECDH over secp256k1 with AES-256, authenticated with HMAC-SHA256, and carries a small proof of work. Messages are not routed to a destination — they are flooded to the whole network and every node stores them for 48 hours, so no relaying peer learns who a message is for. Nothing touches the blockchain and nothing is retained after 48 hours.
This is a long-standing part of the wallet and is not part of Innova's v5 privacy stack: it shares no code with FCMP++, the shielded pool, stealth addresses, or silent payments, and it has not had an external cryptographic review. It does not provide forward secrecy, and it decrypts with your wallet's own keys — there is no separate messaging identity. It has no group chat or channels; sending to several people is N independent 1:1 messages. Use it for convenience, not for information whose disclosure would harm you.
Innova Improvement Proposals (IIPs) formalize all protocol innovations. See IIP_INDEX.md for full specifications and the status vocabulary.
Nothing in the v5 ladder has activated on mainnet. Mainnet gate heights are not
literals in the source: every gate returns
ShiftMainnetV5Activation(base), adding MAINNET_V5_ACTIVATION_SHIFT
(src/v5activation.h, currently 350,040) to its base, so the whole ladder moves
as a unit. The effective heights below are base + shift for the current shift and
are re-derived by the release preflight against a fresh mainnet tip.
| IIP | Title | Status | Mainnet activation |
|---|---|---|---|
| IIP-0001 | Cold Staking (P2CS) | Scheduled | height 8,150,040 |
| IIP-0002 | Shielded Transactions (Pedersen + Bulletproofs + Lelantus) | Scheduled | height 8,151,540 |
| IIP-0003 | Ring Signature Deprecation | Scheduled | height 8,150,040 (mainnet); height 0 on testnet/regtest |
| IIP-0004 | Dynamic Selective Privacy (8 modes) | Scheduled | height 8,151,540 |
| IIP-0005 | Confidential CoinJoin | Scheduled | height 8,151,540 |
| IIP-0006 | FCMP++ Full-Chain Membership Proofs | Scheduled | height 8,151,540 |
| IIP-0007 | Silent Payments + Silent Shielding | Partly active | silent payments: no gate, live. Silent shielding: height 8,151,540 |
| IIP-0008 | Dandelion++ Network Privacy | Active | no fork height — relay policy, on by default |
| IIP-0009 | NullStake V1 (ZK Private Staking) | Scheduled | height 8,151,540 |
| IIP-0010 | NullStake V2 (Poseidon2 + Bulletproof AC) | Scheduled | height 8,151,540 |
The privacy IIPs above carry a ladder height in the source
(FORK_HEIGHT_SHIELDED and its siblings, main.h), but reaching it does not
enable them: the transaction versions they ride (2000–2007) are rejected on
mainnet and testnet at every height, and their production replacement is the
version-2008 envelope gated on Boundary B, height 8,151,540 on mainnet.
docs/BUILD.md has the full steps for Linux, macOS and Windows. In short:
- Install the build dependencies for your platform and Rust (
rustup; the repo pins 1.94.1). - Restore the Rust crates once per clone, in
src/privacy_vnext/rust:CARGO_NET_OFFLINE=false cargo vendor --locked --versioned-dirs --sync upstream/Cargo.toml - Build the daemon:
make -C src -f makefile.unix USE_NATIVETOR=- innovad(makefile.osxon macOS,makefile.mingwon Windows). - Optionally build the Qt wallet (
qmake6 innova-qt.pro && makeon Linux, CMake on macOS, static Qt 6 on Windows).
On Ubuntu 22.04 or later, the two scripts below do all of this for you.
Builds and installs the Innova daemon (innovad) on Ubuntu 22.04, 24.04 or 26.04:
installs the build dependencies and Rust, builds the v5.0.0.0 tag (override with
INNOVA_REF), copies innovad to /usr/bin, and sets up the firewall and swap.
./installdaemon.sh update rebuilds an existing checkout.
bash -c "$(wget -O - https://raw.githubusercontent.com/innova-foundation/innova/master/installdaemon.sh)"
bootstrap.sh replaces the chain data in ~/.innova with the published bootstrap.
Builds the Innova Qt 6 wallet on Ubuntu 22.04, 24.04 or 26.04, from the v5.0.0.0 tag
by default (override with INNOVA_REF).

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.
The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if they don't match the project's coding conventions (see docs/CONTRIBUTING.md) or are controversial.
The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are regularly created to indicate new stable release versions of Innova.
Feature branches are created when there are major new features being worked on by several people.
From time to time a pull request will become outdated. If this occurs, and the pull is no longer automatically mergeable; a comment on the pull will be used to issue a warning of closure. The pull will be closed 15 days after the warning if action is not taken by the author. Pull requests closed in this manner will have their corresponding issue labeled 'stagnant'.
Issues with no commits will be given a similar warning, and closed after 15 days from their last activity. Issues closed in this manner will be labeled 'stale'.
