Blockchain has long been hailed for its security and immutability. However, emerging advances in quantum computing present new threats that could challenge these foundational elements. As technology evolves, so must our approach to security. Informatix Systems is at the forefront of preparing businesses to navigate the upcoming shift with quantum-resistant solutions.
Understanding Quantum Computing
Quantum computing uses quantum bits or qubits that can represent multiple states simultaneously. This allows quantum computers to solve complex problems much faster than classical computers.
While promising for various industries, quantum computing threatens cryptographic systems that blockchain technology relies on, particularly public key cryptography.
How Quantum Computing Threatens Blockchain
Public Key Vulnerabilities
Most blockchain platforms use ECDSA (Elliptic Curve Digital Signature Algorithm) for transaction security. Quantum computers could potentially break ECDSA using Shor’s Algorithm, enabling attackers to forge digital signatures and compromise wallets.
Breaking Hash Functions
Though more difficult, quantum computers could reduce the complexity of brute-forcing hash functions like SHA-256 used in Bitcoin mining, potentially making mining easier and altering the balance of network trust.
Threat to Immutability
If attackers gain quantum access to sufficient private keys, they could reverse transactions or rewrite parts of the blockchain history.
Post Quantum Cryptography: The Way Forward
In response to quantum threats, post quantum cryptography (PQC) offers cryptographic methods designed to be secure against quantum attacks. These include lattice-based, hash-based, and multivariate polynomial algorithms.
Informatix Systems is actively integrating PQC into blockchain applications to future-proof your infrastructure.

FAQ
What is the main quantum threat to blockchain?
The biggest threat is the potential to break cryptographic algorithms like ECDSA, allowing malicious actors to access wallets and forge signatures.
Is blockchain still safe today?
Yes. Quantum computers have not yet reached the scale necessary to break blockchain encryption. However, planning for quantum readiness is essential.
What is post quantum cryptography?
It refers to encryption methods that are secure against both classical and quantum computers. These are being adopted to future-proof digital systems.
Can quantum computing reverse blockchain transactions?
In theory, with access to sufficient keys, quantum computers could manipulate or reverse transactions, compromising the integrity of the chain.
How can Informatix Systems help prepare for quantum threats?
We offer quantum threat assessments, integration of post quantum cryptography, and development of quantum-resilient blockchain systems.
