Wu Blockchain reports that Coinbase has released recommendations for Bitcoin quantum-resistant security technology, stating that it currently holds custody of assets amounting to about 5% of the total BTC supply. Coinbase believes that Bitcoin's quantum-resistant migration could take years and suggests starting preparations early. Coinbase recommends exploring scalable signature schemes like BIP-360 (P2MR) and P2TRv2, and adopting a phased transition mechanism that combines traditional signatures with post-quantum signatures. Additionally, it emphasizes the need to assess the impact of new algorithms on block space, verification performance, and institutional multi-party computation (MPC) custody. For BTC that cannot be migrated in time, has lost private keys, or has remained inactive for a long time, Coinbase advocates for separate discussions to address these cases to avoid delaying the overall quantum-resistant upgrade process. https://www.(wublock123.com)/news/coinbase-bitcoin-quantum-resistant-migration-recommendation-phased-intro-new-signature-mechanism-70003
