Tom Lee, chairman of Bitmine, said that the bitcoin network has not yet reached a consensus on protection against quantum computing. According to him, a breakthrough in this area, conventionally called "Q-day", may occur by 2028. Lee noted that the developers of the Ethereum, Solana and Canton networks are already working on quantum-stable systems, which provides them with a technological advantage.

This topic is being discussed against the background of comments by IBM CEO Arvind Krishna, who recommended that investors exercise caution in the next three to four years due to quantum threats. In response, CNBC TV host Jim Kramer announced his intention to sell his assets in bitcoin. Lee also added that financial infrastructure and government systems will need increased protection, as AI and quantum tools accelerate the search for vulnerabilities.

Lee's statements have received comments from industry experts. Adam Back, co-founder of Blockstream, clarified that bitcoin uses digital signatures rather than encryption to conduct transactions, although powerful quantum computers can pose a threat to certain cryptographic keys. Mike Belshe, CEO of BitGo, noted that his company's custody services are already protected from quantum attacks. Possible updates such as BIP-360 and the vulnerability of old public key wallets are being discussed in the bitcoin community. The main task for the network remains to achieve a broad consensus on the implementation of new protocols.
