IBM’s quantum computer cracked a 6-bit ECC key—safe for now, but experts warn Bitcoin and Ethereum must prepare for quantum threats.

Capgemini’s analysis does not specifically mention Bitcoin, but it talks about how ECC, the technology behind the blockchain’s private key, is vulnerable to quantum computing.

Bitcoin relies on several algorithms to secure the coin from theft. Prominent among these is the Elliptic Curve Digital Signature Algorithm (ECDSA). An ECDSA employs asymmetric encryption to ...

El Salvador, the world’s first nation to adopt Bitcoin as legal tender, has moved to strengthen the security of its national cryptocurrency reserve amid growing concerns over the threat posed by ...

El Salvador secures its reserves by splitting holdings into multiple wallets, mitigating Bitcoin quantum security risks from future threats.

Recently, Project Eleven (a quantum computing research group) announced a 1 bitcoin reward for the first team able to complete a challenge to demonstrate breaking a ECC (elliptic curve cryptograph) ...

El Salvador plans to move its Bitcoin from a single wallet into 14 fresh wallets to enhance the security of its reserves.

Bitcoin relies on several algorithms to secure the coin from theft. Prominent among these is the Elliptic Curve Digital Signature Algorithm (ECDSA). An ECDSA employs asymmetric encryption to ...

Quantum computers are capable of breaking elliptic curve DSA (ie. given a public key, a quantum computer can very quickly find the private key), but they cannot similarly reverse hash algorithms (or ...

This is a 256-bit private key is the basis for the Bitcoin wallet private key (after being encoded as ASCII characters), and as the 512-bit public key (after being sent through an elliptic curve ...
