Part one explained the physics of quantum computing. This piece explains the target — how bitcoin's encryption works, why a ...

Hidden inside a simple color-mixing analogy is one of the most elegant ideas in cryptography, a mathematical trap door that lets two strangers build a shared secret in plain sight. This is the story ...

Somewhere on a blockchain right now, a Bitcoin address that last moved coins in 2015 is sitting with its public key fully ...

Diffie-Hellman’s key-exchange method runs this kind of exponentiation protocol, with all the operations conducted in this way ...

However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

Bitcoin transactions could be resistant to quantum attacks without changing the network’s core rules, a new proposal contends ...

Quantum computing exists in a sort of superposition with regard to cryptography – it's both a pending threat and a technology of no immediate consequence for decryption. Now, two well-known ...

Cloudflare has set a 2029 deadline for full post-quantum security, prioritizing authentication over encryption to counter ...

A quantum computing-fuelled collapse of Bitcoin has lurched closer than previously thought, potentially sparking chaos across ...

Google's quantum paper made headlines with that number. Here's what it means, what's actually at risk, and why 6.9 million bitcoin are more exposed than the rest.

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought ...

Google Quantum just cut the qubit requirement to break Bitcoin encryption by 20x, and 6.7 million crypto addresses are in risk.
