WHAT IS THIS ALL ABOUT

This is a new initiative by Bitcoin developers that is aimed at safeguarding the block chain against potential threats from quantum computers because Quantum computers still in their early stages of development pose a future risk to Bitcoin because they could theoretically break the cryptographic algorithms protecting user funds specifically those exposed in certain address types.When you send Bitcoin your public key becomes visible on the block chain a quantum computer could use Shor’s Algorithm to compute your private key from your public key allowing theft of your funds.

QUANTUM VULNERABLE ADDRESSES

Some older Bitcoin addresses particularly those that have already revealed their public key by spending coins are considered quantum-vulnerable they include P2PK ,P2PKH once spent, the public key is exposed Quantum computers could in theory, derive the private key from the public key, allowing them to steal funds from those addresses


This proposal is forward-looking because it's a defensive  mechanism or step against a potentially massive cryptographic shift. It’s still in early discussion stages and would require broad consensus to implement via a soft fork.
