Coin Metrics co-founder: Quantum computing is the biggest long-term risk to Bitcoin's core cryptography
PANews, October 21—According to CoinDesk, Coin Metrics co-founder Nic Carter stated that quantum computing is the greatest long-term risk to the core cryptography of bitcoin. He explained the one-way nature of deriving public keys from private keys via the secp256k1 elliptic curve, and pointed out that exposing public keys on-chain when spending transactions increases the potential attack surface. Carter suggested avoiding address reuse in the near term to reduce public key exposure, and in the long term, advancing post-quantum signature schemes and feasible migration paths. His series of articles will subsequently discuss the scenario of a “post-quantum break”.
