02 / THE SCIENCE

Beyond the buzzword.
Inside the mathematics.

Post-quantum cryptography runs on conventional computers. Its purpose is to withstand attacks from both classical and future quantum machines.

THREAT MODEL / 01+

The risk is in the signature.

A sufficiently capable quantum computer could use Shor’s algorithm to break the discrete-logarithm assumptions behind widely used elliptic-curve signatures. That creates a long-term migration challenge for blockchain accounts.

A wallet upgrade alone cannot secure an entire network. Account validation, consensus, bridges, and recovery paths need to be considered together.

03 / RESISTANCE ARCHITECTURE

One vault.
Multiple layers of thinking.

Explore the proposed architecture behind QuantVault. From account policy to network design, every layer has a different job.

Your account. Your rules.

Explore programmable account policies for signing, recovery, and algorithm upgrades. ERC-4337 supplies an account-abstraction framework; quantum resistance would require additional validated cryptography.

THE IMPORTANT QUESTIONS

Precision matters.

Does “quantum-resistant” mean unhackable?

No. It describes resistance to particular quantum attacks under specific assumptions. Software bugs, compromised devices, phishing, and flawed implementation remain security risks.

Is ERC-4337 a blockchain or quantum-security standard?

Neither. It is an Ethereum account-abstraction specification that supports custom account validation. Using it does not automatically make a wallet or Ethereum quantum-resistant.

Can I use QuantVault to store funds today?

No. This site presents a product concept and interactive design preview. The wallet, extension, mobile apps, and Resistance Chain have not been released here.

What must happen before a secure release?

A concrete protocol specification, tested cryptographic implementations, network compatibility work, independent security assessment, and clearly documented deployment parameters.
