Understanding the cryptographic innovations that make QUBITUM quantum-resistant and private by default
ZK-STARKs (Zero-Knowledge Scalable Transparent Arguments of Knowledge) allow QUBITUM to prove transaction validity without revealing any sensitive information about the transaction itself.
Unlike zk-SNARKs, STARKs don't require a trusted setup ceremony that could be compromised
Based on hash functions and information theory, inherently resistant to quantum attacks
Fast verification time enables efficient transaction processing
Proof size grows logarithmically with computation complexity
// Generate ZK-STARK proof for transaction
let proof = stark::prove(
&transaction,
&witness,
StarkConfig {
security_level: 128,
hash: "Poseidon",
field: "BN254",
}
)?;
// Verify proof without knowing transaction details
let valid = stark::verify(&proof, &public_inputs)?;
// Returns: true/false (no information leak)CRYSTALS-Dilithium is a NIST-approved post-quantum digital signature algorithm based on lattice cryptography. It provides security against both classical and quantum computer attacks.
Secure against both classical and quantum attacks
Official post-quantum standard approved by NIST
Fast cryptographic operations for real-world use
Compact sizes for efficient blockchain transactions
Lattice-based cryptography relies on the hardness of problems like Learning With Errors (LWE) and Short Integer Solution (SIS). These problems remain computationally hard even for quantum computers, unlike the discrete logarithm and factoring problems that underpin current cryptocurrency security.
Combining the proven security of proof-of-work with the efficiency and governance of proof-of-stake
Miners compete to find valid blocks using QubitumHash, a memory-hard algorithm requiring 4GB RAM
5 staking tickets are randomly selected from the pool to vote on the block
Block is accepted if at least 3 of 5 tickets vote to approve (60% threshold)
Attackers need both hash power AND stake to manipulate the chain
Ticket holders vote on protocol upgrades and treasury spending
63% to miners, 27% to stakers, 10% to treasury for development
PoS voting provides faster probabilistic finality than pure PoW
LSAG (Linkable Spontaneous Anonymous Group) signatures hide the true sender among a group of possible signers while preventing double-spending.
With 8 members, there's only a 12.5% chance of identifying the real signer. QUBITUM supports rings from 4-64 members.
Choose between 4-64 ring members based on privacy needs
Unique per-output identifiers prevent double-spending without revealing identity
One-time addresses for each transaction prevent address linkability
Pedersen commitments hide transaction amounts
Multiple layers of network-level privacy to prevent traffic analysis and IP correlation
Transactions propagate through a "stem" phase before "fluffing" out to the network, making it nearly impossible to identify the origin node.
Optional Tor support for users requiring maximum anonymity. All traffic can be routed through the Tor network for IP address protection.
I2P (Invisible Internet Project) integration provides an alternative anonymity layer with garlic routing for enhanced privacy.
QUBITUM is written from scratch in Rust, a systems programming language known for memory safety, zero-cost abstractions, and fearless concurrency.
No null pointers, buffer overflows, or data races by design
C/C++ level speed with modern language ergonomics
Rich type system and ownership model catch bugs at compile time
Cargo package manager, rustfmt, clippy, and excellent documentation
