Marathon Digital's Bitcoin L2 project Anduro announced that Bitcoin has taken an important step forward in achieving future quantum resistance. The updated BIP 360 has been merged into the official Bitcoin GitHub repository, introducing the Pay-to-Merkle-Root (P2MR) output type. This update addresses the quantum vulnerability of Taproot's key path spending issue while maintaining compatibility with Tapscript and script trees. It lays the foundation for post-quantum signatures and is introduced via a soft fork to ensure no impact on existing Taproot outputs. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=56636
