Crypto Expert Nic Carter Warns of Quantum Computer Threat to Bitcoin

Crypto expert Nic Carter is calling for immediate action by Bitcoin developers in light of the increasing threat from quantum computers. Bitcoin is based on elliptic curve cryptography (ECDSA), which could potentially be broken by powerful quantum computers in the future.

Particularly critical: The U.S. National Institute of Standards and Technology (NIST) already recommends phasing out ECDSA gradually, as it is considered "quantum-vulnerable." According to an analysis by Chaincode Labs, approximately 6.7 million BTC are vulnerable to quantum attacks, including 1.72 million BTC from early Pay-to-Public-Key holdings ^[1].

Carter emphasizes that blockchains are particularly vulnerable compared to other systems. A sufficiently powerful quantum computer could extract private keys from exposed public keys or redirect transactions between transmission and block confirmation.

While Ethereum appears better positioned due to smart contract flexibility and Solana through experimental approaches, Carter warns: "Quantum computers have evolved from a distant theoretical possibility to a purely technical challenge." The development of quantum hardware is progressing faster than expected, which is why Bitcoin developers must begin preparations today ^[1].
