Bitcoin just made a meaningful step toward future quantum resistance πͺ
An updated version of BIP 360 has just been merged into the official Bitcoin BIP GitHub repository.
The update introduces Pay-to-Merkle-Root (P2MR), a proposed new output type that omits Taprootβs quantum-vulnerable key-path spend while preserving compatibility with Tapscript and script trees.
It also includes:
- Removal of Taprootβs quantum-vulnerable key-path spend in a separate opt-in new output type.
- A foundation for introducing post-quantum signatures while using Tapscript/script tree for spend time optionality.
- The change is a soft fork that does not affect existing Taproot outputs.
- Addition of Isabel Foxen Duke as co-author, to ensure the BIP was clear and understandable to the general public, not just the Bitcoin developer community.
The BIP also addresses criticism about Bitcoin devs not taking the quantum threat seriously. We are grateful to every Bitcoin contributor who took the time to review and provide feedback.

Mara Foundations Isabel Foxen Duke on where Bitcoin actually stands against quantum:
"For the most part, most addresses that are already used are quantum resistant against most types of attacks."
"There are some concerns about more advanced attacks. For extra levels of security around those types of attacks, or full Bitcoin quantum resistance, you will want to use a quantum resistant address type."
βThe fact that AI can prove theorems that have been hard does not indicate in any way that problems assumed to be hard are not. Our assumptions on hard problems are not based merely on human fallibility but on a belief that inherent hardness exists.β

MARA Foundation is co-hosting a discussion with @allocinitxyz, the team behind the new Shielded Bitcoin protocol & PIPEs.
We'll unpack their recent announcement, gauge progress on PIPEs, and address key questions from the community on its viability for both covenants and privacy β without a soft fork.
