PANews reported on December 22 that Blockstream CEO Adam Back criticized Nic Carter for exaggerating the threat of quantum computing to Bitcoin. F2Pool co-founder Wang Chun subsequently agreed, stating that quantum computing is currently a "bubble," and even with advancements in Moore's Law, a substantial threat from secp256k1 (the elliptic curve cryptography standard used by Bitcoin to generate addresses and signatures) is still 30 to 50 years away.
