Quantum Computing Poses Long-Term Risk to Bitcoin's Cryptography

According to PANews, Coin Metrics co-founder Nic Carter has identified quantum computing as the most significant long-term threat to Bitcoin's core cryptography. Carter explained the one-way nature of deriving public keys from private keys using the secp256k1 elliptic curve and highlighted that public keys become exposed on the blockchain when transactions are spent, increasing the potential attack surface. Carter advised against address reuse in the near term to minimize public key exposure. He also emphasized the importance of developing quantum-resistant signature schemes and feasible migration paths in the long term. Carter's series of articles will continue to explore scenarios in a 'post-quantum break' world.
