Every time you send a message, sign a transaction, or prove your identity online, you're relying on cryptography. It's the mathematical foundation that makes digital security possible.
But here's what most people don't realize: the cryptography protecting nearly everything online today is living on borrowed time.
Quantum computers—machines that exploit the strange properties of quantum physics—are advancing rapidly. When they become powerful enough, they'll be able to break the encryption that protects your bank account, your messages, your cryptocurrency, and your identity. Not in years. In minutes.
Most security software hasn't even begun to address this threat. Zbelthas has.
This document explains how we protect your data—not just against today's threats, but against tomorrow's as well.
Most encryption today relies on mathematical problems that are extremely hard for computers to solve. For example, if you multiply two very large prime numbers together, it's easy to get the result. But given only the result, figuring out which two primes were multiplied is incredibly difficult—so difficult that even the fastest supercomputers would take longer than the age of the universe to solve it.
This asymmetry—easy in one direction, practically impossible in reverse—is the foundation of modern cryptography.
Quantum computers don't work like regular computers. They can explore many possibilities simultaneously, using a property called superposition. For certain types of problems—including the mathematical problems that underpin current encryption—this gives them an enormous advantage.
A quantum computer running an algorithm called Shor's algorithm could factor large numbers in hours or days instead of billions of years. This would break RSA, the encryption that protects most internet traffic. It would break elliptic curve cryptography, which protects Bitcoin and Ethereum. It would break the digital signatures that verify software updates, financial transactions, and legal documents.
Here's the scary part: attackers don't need to wait for quantum computers to be built. They can record encrypted data today and store it. When quantum computers become available, they can decrypt everything they've collected.
This means that sensitive data you're transmitting right now—financial records, medical information, private communications—could be exposed years from now. For data that needs to remain confidential for decades, the quantum threat is already here.
No one knows exactly when quantum computers will become powerful enough to break current encryption. Estimates range from 5 to 15 years. But cryptographic transitions take time—often a decade or more to fully deploy new standards. If we wait until quantum computers arrive, it will be too late.
That's why Zbelthas implements post-quantum cryptography today.
Post-quantum cryptography uses mathematical problems that are believed to be hard even for quantum computers. Instead of relying on factoring or elliptic curves, these algorithms use problems from lattice mathematics—geometric structures in high-dimensional spaces that remain difficult even with quantum advantages.
The U.S. National Institute of Standards and Technology (NIST) has spent years evaluating post-quantum algorithms. After rigorous analysis by cryptographers worldwide, they've published new standards:
ML-DSA-87 (also known as Dilithium) for digital signatures. This is what Zbelthas uses to sign transactions and verify authenticity. The "87" indicates Category 5 security—the highest level, equivalent to 256-bit classical security.
ML-KEM-768 (also known as Kyber) for key exchange. This is what Zbelthas uses to establish secure communication channels for messaging.
These aren't experimental algorithms. They've been analyzed by the global cryptographic community for years and have been standardized by NIST as FIPS 203 and FIPS 204.
Despite our confidence in post-quantum algorithms, we don't rely on them alone. Zbelthas uses a hybrid approach: every cryptographic operation uses both classical and post-quantum algorithms.
When you sign a transaction, Zbelthas creates two signatures: one using classical cryptography (like the algorithms Bitcoin and Ethereum use today) and one using post-quantum cryptography. Both signatures must verify for the transaction to be valid.
Why do this? Defense in depth. If somehow the post-quantum algorithms turn out to have weaknesses we don't know about yet, the classical algorithms still protect you. If quantum computers break the classical algorithms, the post-quantum algorithms still protect you. An attacker would need to break both simultaneously—a much harder task.
In a traditional cryptocurrency wallet, your private key exists as a single piece of data. It might be stored in a file, in memory, or on a hardware device. But wherever it is, it's complete—and if an attacker gets it, they control your assets.
This is a fundamental vulnerability. No matter how well you protect that key, it's a single point of failure.
Zbelthas uses a technique called threshold cryptography to eliminate this vulnerability. Your private key is mathematically split into three pieces, called shares. These shares are stored in different locations with different protections.
Here's the crucial part: your complete private key never exists. Not when you create your wallet. Not when you sign a transaction. Not ever.
When you need to sign a transaction, two of the three shares work together mathematically to produce a valid signature—without ever being combined into a complete key. Each share performs part of the computation, and the results are combined to create the final signature.
If an attacker steals one share, they get nothing. Mathematically, a single share reveals zero information about your private key. It's not like having one-third of a password—it's like having nothing at all.
You can lose one share and still access your funds. Because only two shares are needed to sign, you have redundancy built in. If one share is lost or corrupted, you can still use the other two.
Compromise requires multiple independent breaches. An attacker would need to compromise two different storage locations with two different protection mechanisms. This is dramatically harder than compromising one.
Even with distributed keys, there's a moment of vulnerability: when a share is loaded into memory to perform a cryptographic operation. If an attacker can read your device's memory at that moment—through malware, a cold boot attack, or forensic analysis—they might be able to extract the share.
Zbelthas uses multiple techniques to address this:
Every piece of sensitive data in Zbelthas is automatically erased from memory the moment it's no longer needed. We don't rely on the operating system's garbage collection, which might leave data in memory indefinitely. We explicitly overwrite sensitive memory with zeros before releasing it.
While keys are in use, they're stored in protected memory regions that resist extraction. We use techniques that make it difficult for attackers to locate and read key material even if they can access memory.
On platforms that support it, we store keys in hardware security modules (TPM, Secure Enclave, StrongBox) where they're protected by dedicated security hardware. Keys in these modules can perform cryptographic operations without ever being exposed to the main processor or operating system.
Sometimes attackers don't need to break the mathematics of cryptography. Instead, they observe how the cryptographic operations are performed—how long they take, how much power they consume, what patterns they create in memory access.
These "side channels" can leak information about secret keys. For example, if a cryptographic operation takes slightly longer when processing a "1" bit versus a "0" bit, an attacker who can measure timing precisely might be able to reconstruct the entire key.
Zbelthas implements all cryptographic operations in constant time. This means every operation takes exactly the same amount of time regardless of the data being processed. There are no shortcuts, no early exits, no data-dependent branches.
When comparing two values, we don't stop at the first difference—we always compare every byte. When performing calculations, we don't skip steps even if we could. This eliminates timing side channels.
We also protect against attacks that observe which memory locations are accessed. Our key storage uses techniques that make all access patterns look identical, regardless of which key is being used. An attacker watching memory access can't tell which key you're using or what operation you're performing.
Zbelthas implements cryptographic algorithms standardized by NIST:
FIPS 204 (ML-DSA): Our post-quantum signature algorithm
FIPS 203 (ML-KEM): Our post-quantum key exchange algorithm
FIPS 197 (AES): Our symmetric encryption algorithm
FIPS 180-4 (SHA-2): Our hash functions
These standards represent the consensus of the global cryptographic community on secure algorithms and implementations.
Our cryptographic architecture is designed to meet the requirements of European regulations:
eIDAS 2.0 establishes requirements for qualified electronic signatures. Our ML-DSA-87 implementation meets Category 5 security requirements, the highest level defined by NIST.
GDPR requires appropriate technical measures to protect personal data. Our encryption and key management exceed these requirements.
You don't need to understand the mathematics to benefit from it. Here's what our cryptographic architecture means in practical terms:
Your assets are protected against quantum computers. While most cryptocurrency is vulnerable to future quantum attacks, yours isn't.
Your keys can't be stolen in one breach. An attacker would need to compromise multiple independent systems to access your funds.
Your secrets don't linger in memory. Sensitive data is automatically erased the moment it's no longer needed.
Side-channel attacks don't work. Our constant-time implementations eliminate the subtle leaks that sophisticated attackers exploit.
You're using proven standards. Our algorithms have been vetted by the global cryptographic community and standardized by NIST.
This is the mathematical foundation that makes Zbelthas secure—not just today, but for decades to come.
