QRAMP protocol, explained: Can Bitcoin’s 21-million cap survive the future?

With threats from quantum computing and growing cross-chain demand, QRAMP offers a non-custodial approach to protect and project Bitcoin.

The 21-million Bitcoin limit is one of the most iconic features of the protocol — a hard-coded cap that defines its scarcity, value proposition and appeal as “digital gold.” But what happens if that system is threatened from two sides: by powerful quantum computers on one end and by increasing demand for cross-chain Bitcoin utility on the other?

Short for quantum-resistant asset mapping protocol, QRAMP is a framework proposed in early 2025 by Bitcoin developer Agustin Cruz. It’s designed to do two things at once: protect Bitcoin from future quantum attacks and unlock a safer way to extend Bitcoin into other blockchain ecosystems without compromising custody or supply limits.
