Quantova

Foundational blockchain platform powering decentralized apps, stablecoins, and post quantum resistant smart contracts via QVM

[Quantova @Quantovafnd]

Quantova is a trusted execution layer powered by QVM, a natively post-quantum virtual machine engineered from first principles without dependence on legacy cryptographic signing paths

Lattice-based verification, deterministic execution semantics, SHA-3 domain separated state integrity, and governed execution policy are enforced directly at the protocol layer

Execution validity and security policy operate as a single deterministic system designed for post-quantum infrastructure

3/3 Quantova supports all three simultaneously under a unified account model, allowing participants to select the scheme appropriate to their security and performance requirements. The protocol is designed to accommodate additional schemes as cryptographic research advances

1/3 🧵Post-quantum cryptographic research has produced a range of candidate algorithms with different security assumptions, performance characteristics, and implementation profiles

[Quantova @Quantovafnd]

2/3 Lattice-based schemes such as Dilithium and Falcon offer compact signatures and efficient verification. Hash-based schemes such as SPHINCS+ offer conservative security assumptions derived from hash function properties rather than algebraic structures, at the cost of larger signature sizes. Each represents a different point on the tradeoff curve

Proud to see Quantova contributing to discussions around quantum threats and the future of cryptographic security at #BitcoinSeoul2026

As awareness of post-quantum risk continues to grow, we're excited to see our community helping drive the conversation forward and representing Quantova on the global stage

[Quantova @Quantovafnd]

@monero If Jamtis-PQ achieves forward secrecy against ECDLP breaks at the address layer, what's the threat model for the signing layer? Are transaction authorizations still ECDSA dependent, or does the full stack migrate?

[Quantova @Quantovafnd]

The primitive being optimized is elliptic curve point addition, the exact operation Shor's runs repeatedly to recover a private key from a public key

4/4 As institutional settlement, tokenized assets, and sovereign digital infrastructure expand globally, the importance of native post-quantum execution environments will only continue increasing..

[Quantova @Quantovafnd]

1/4 🧵 Most blockchain discussions around post-quantum security focus only on signatures

The deeper challenge is execution architecture..

Replacing signatures alone does not solve how consensus, validator coordination, state transition logic, bridge infrastructure, and long duration settlement systems behave under post-quantum conditions

[Quantova @Quantovafnd]

3/4 Quantova was architected differently

Post-quantum cryptographic enforcement is integrated directly into protocol architecture, execution systems, validator infrastructure, and SDK tooling

The objective is long duration settlement infrastructure designed for advanced computational conditions

The cryptographic timeline is compressing faster than most blockchain infrastructure anticipated..

As quantum investment and computational capability accelerate, post-quantum migration shifts towards a longterm infrastructure requirement. Networks built around classical cryptographic assumptions will eventually face increasingly difficult coordination and migration challenges

Quantova has been developing native post-quantum Layer 1 architecture since 2021..

The moment networks move from ~65B ECDSA signatures to ~2.4KB ML-DSA signatures, the operational characteristics of distributed systems change significantly - network propagation, bandwidth consumption, storage requirements, mempool scaling, and verifier performance all become heavier..

Great to see major chains testing real execution behavior under post-quantum conditions

[BNB Chain Developers @BNBChainDevs]

A lot of people assume the hardest part of post-quantum cryptography is the cryptography itself.

In our testing, that wasn’t really the case.

The bigger challenge came from the amount of additional data moving through the network once quantum-resistant signatures were introduced.

A single transaction signature increased from 65 bytes to ~2.4 KB.

That pushed:
• Transaction size from 110 B → ~2.5 KB
• Block size from ~110 KB → ~2 MB
• Native transfer TPS from 4,973 → 2,997

The result was higher cross-region propagation overhead and lower throughput ceilings, even though verification performance itself remained manageable.

One thing the industry still underestimates is that post-quantum migration is not just about selecting the best algorithm..

Execution determinism, side channel behavior, threshold compatibility, hardware support, state growth, verifier costs, governance complexity etc will heavily influence which schemes are actually deployable at protocol scale

🔔Post-Quantum Signatures: NIST's Second Wave

In August 2024, NIST finalized its first PQC standards: ML-KEM (key exchange), ML-DSA, and SLH-DSA (signatures). A third signature, Falcon (FN-DSA, FIPS 206), is still in draft.

Last week, NIST announced the nine candidates advancing to Round 3 of a parallel competition aimed at additional signature schemes, explicitly chosen to fill the gaps left by the first wave.

Each of the standardized signatures comes with sharp trade-offs. None of them is naturally suited to threshold signing, and all have signatures that are large compared to ECDSA's 64 bytes.
➡️ SLH-DSA (SPHINCS+, hash-based) The most conservative choice: its security rests only on the collision resistance of a hash function. The price is enormous signatures (7–50 KB !!!). It is the safest pick for very long-lived signatures (firmware, archival, some blockchains such as QRL).
➡️ML-DSA (Dilithium, lattice-based). Compact and fast, while elegant, is younger than hash-based assumptions. It is becoming the default for TLS, PKI, and most non-blockchain ecosystems (~2.4 KB signatures).
➡️Falcon (FN-DSA, lattice-based). The smallest of the three (~666 B at NIST-I), which is why Algorand and Solana selected it. Its drawback: signing relies on floating-point arithmetic, making error-prone and side-channel-resistant/ constant-time implementations notoriously hard. Its FIPS 206 standard is still in draft.

🔍Most blockchains are leaning towards customized shorter versions of SLH-DSA.

NIST is organizing a second wave of standardization. The goal is twofold: shrink signature sizes and diversify the underlying mathematics so a single cryptanalysis breakthrough cannot break everything. The nine Round 3 finalists span five families:
🔸 Isogeny: SQIsign
🔸 Lattice: HAWK
🔸 MPC-in-the-Head: MQOM, SDitH
🔸 Multivariate: MAYO, QR-UOV, SNOVA, UOV
🔸 Symmetric-based: FAEST

Notably, no code-based scheme survived. Both Round 2 candidates were eliminated: LESS and CROSS were dropped because of 2 attacks

👉 Two candidates worth watching
⏩ SQIsign produces the smallest known post-quantum signatures by a wide margin: from 148B to 292B (depending on the level of security), with sub-130-byte public keys. That is the only PQC signature scheme today that even approaches the bandwidth profile of ECDSA, extremely attractive for blockchains, certificates, and firmware. The catch: isogeny-based cryptography is still young, signing is mathematically intricate, and side-channel hardening is an active research area.
⏩HAWK is essentially "Falcon without the floating-point." It is a lattice hash-and-sign scheme producing 555 B signatures at NIST-I (smaller than Falcon's 666 B) and can be implemented purely with integer arithmetic, a major engineering win.

NIST has said the Round 3 review will last roughly two years and that any multivariate winners are unlikely to be standardized without yet another round. Realistically, the earliest a new signature standard will land alongside ML-DSA and SLH-DSA is 2028.

The urgency to migrate has grown sharply, yet the current standards still have significant drawbacks, and this last-minute selection round, while necessary, collides head-on with the migration timeline.
