Matt Corallo: P2MR and P2TRv2 offer similar quantum safety if addresses are reused — P2MR and P2TRv2 quantum safety

Matt Corallo has remarked that P2MR and P2TRv2 are essentially equivalent in terms of future quantum safety, particularly when users reuse addresses.

Corallo highlights that address reuse remains common practice, which may affect the quantum-resistance properties of these protocols. His comments focus on the importance of understanding security implications in ongoing cryptographic development.

But we saved everything 🙂.

Earlier, Corallo addressed access issues for bitcoins stored as raw public keys before the introduction of seedphrases and BIP 32. He stated these early bitcoins require owner intervention for recovery, according to his comments in a previous article. The remarks add context to his recent focus on address practices and cryptographic security.
