Quantum-resistant Security
QANplatform, the quantum-resistant blockchain platform
💡[Definition] Quantum-resistant:
Quantum-resistant algorithms — also known as post-quantum, quantum-secure, or quantum-safe — are cryptographic algorithms that can fend off attacks from quantum computers.
[Market problem]: Quantum computers can break 99% of today's blockchain platforms
IBMs 1,121 qubits quantum computer targeted for 2023 release will be able to break 99% of today's blockchain platforms and cryptocurrencies like Bitcoin, Ethereum, Solana, Cardano, Ripple, Polkadot, etc.

QANplatform, the quantum-resistant blockchain platform

The quantum computer threat is no longer just a FUD, as IBM recently announced they would release a 1,121+ qubit quantum computer that will break the cryptography behind 99% of today’s blockchain platforms.
The most worrying and already proven part is that they will be able to break most asymmetric cryptography-related schemes, including the digital signature scheme used by Bitcoin and Ethereum, etc.
In short, we trusted these algorithms because incrementing the key size would increase the hardness of breaking it exponentially. Quantum computers will linearly tackle this, meaning doubling the key size will only need double the qubits to break. Everything we considered safe so far would be gone for this reason.
Based on the latest post-quantum cryptographic research (1)(2)(3)(4) all wallets relying on EC cryptography that have at least 1 outgoing transaction will break by a 1,121+ qubits quantum computer.

QANplatform's Lattice-based post-quantum cryptographic algorithm implemented in Rust programming language

One of QANplatform’s 4 IPs (Intellectual Properties) next to Proof-of-Randomness (PoR) consensus algorithm, Multi-language smart contract development (Hyperpolyglot), Rapid cloud deployment is the Lattice-based post-quantum cryptographic algorithm implemented in Rust programming language.
We implemented a post-quantum signature scheme that is used to cross-sign transactions. This was necessary so that as quantum computers become available we'd have an immediate solution as opposed to anyone else on the market.
NIST has said it will announce its final endorsements for a new encryption standard within the next 18 months. So what does the NIST long-list tell us about the future of cybersecurity? Well, there’s a good chance that it will involve something called lattice-based cryptography. Three of the four encryption finalists come from this family of algorithms.” Fortune
Key Takeaways — [Quantum-resistant Security]:
  • Quantum computers can break 99% of today's blockchain platforms.
  • Upgrading cryptography primitives in existing blockchain implementations won’t save them from the quantum threat.
  • All wallets relying on EC cryptography which have at least 1 outgoing transaction will break.
  • One of QANplatform's IPs is the Lattice-based post-quantum cryptographic algorithm implemented in Rust programming language.
  • Lattice-based post-quantum cryptography is in the top NIST candidates.
