Coinbase urges blockchain developers to begin quantum-resistant migration preparations immediately.

CoinFeed reported on June 12th that, according to Decrypt, Coinbase's Quantum Advisory Committee released a report urging blockchain developers to immediately begin preparations for quantum-resistant migration, warning that unresolved issues with abandoned and vulnerable tokens could become one of Bitcoin's biggest challenges. The report estimates that approximately 7 million Bitcoins are vulnerable to future quantum attacks due to public key exposure and address reuse. While no quantum computer can currently break blockchain encryption, the possibility of such a computer emerging as early as 2030 is high. The report proposes three solutions for handling tokens that have not been migrated to quantum-safe addresses: permanently freezing or destroying them after a deadline; doing nothing and letting users decide; and taking a compromise, such as limiting the number of vulnerable tokens that can be moved per block, or allowing users to pre-commit to migration.
