Full post quantum security at the lowest cost
Post quantum cryptography is often assumed to be expensive. On Quantova it is not. The protocol enforces post quantum security at every layer and still settles transactions for a typical fee of about five cents, capped at ten cents, with deterministic finality in about three seconds. The figures below are drawn from the protocol fee configuration, not marketing estimates.
Priced by work, capped by the protocol
Every transaction pays a base fee priced by its computational weight, including a small charge for post quantum signature verification so the network cannot be spammed for free. A congestion multiplier is fixed, so fees do not surge under load. The mandatory fee is hard capped by the protocol and can never exceed about ten cents.
- ✓Base fee priced by weight, with a charge for post quantum verification
- ✓Fixed congestion multiplier, so fees do not ramp under demand
- ✓A hard protocol cap of about ten cents on the mandatory fee
- ✓Base fees route in full to the Quantova treasury
| Fee | Amount |
|---|---|
| Transaction, typical | about $0.05 |
| Transaction, hard cap | $0.10 maximum |
| Congestion multiplier | Fixed, no surge pricing |
| Bridge, outward | 0.1% flat |
| Naming, 5+ characters | $5 per year |
| Base fee recipient | Quantova treasury |
| Validator share of a tip | 0.2% |
Secure, fast and low cost at the same time
Most networks trade one property for another. Quantova holds post quantum security, deterministic finality and a low capped fee together. Figures for other networks are approximate industry references and vary by source and conditions.
| Network | Typical fee | Finality | Signatures | Post quantum |
|---|---|---|---|---|
| Quantova | $0.05 | about 3s | Falcon, Dilithium, SPHINCS+ | Yes |
| Bitcoin | Variable, often $1 to $5+ | about 60 min | ECDSA secp256k1 | No |
| Ethereum | Variable, often $1 to $20+ | about 13 min | ECDSA secp256k1 | No |
| Solana | Fractions of a cent | about 13s | EdDSA ed25519 | No |
| Avalanche | Variable | about 1 to 2s | ECDSA secp256k1 | No |
| Algorand | Fractions of a cent | about 3s | EdDSA ed25519, VRF | No |
Quantova figures are from the protocol fee configuration and consensus design. Other figures are approximate public references for orientation only. The defining difference is the cryptography: Quantova is the only network here secured by NIST approved post quantum signatures.
36 blockchains, every one secured on the post quantum VM
Quantova bridges 36 networks and 78 assets onto the Quantova Virtual Machine. Every chain below relies on classical signatures that a quantum computer can break. When their assets move onto Quantova they inherit post quantum security by default. Throughput figures are approximate industry references.

Throughput figures are approximate public references for orientation and vary by source, version and network conditions. The consistent fact is the cryptography: every network above uses classical elliptic curve or related signatures that a quantum computer can break, while Quantova uses NIST approved post quantum signatures and removes the verifiable random function entirely.
