Part 4/11:
Quantum hardware is advancing exponentially, with companies like Microsoft and IBM pushing the boundaries of qubit development. Google's Willow chip has only 105 qubits, but estimates suggest the need for around 13 million qubits to effectively crack Bitcoin's cryptography. While this might seem distant, quantum growth is accelerating rapidly, with recent innovations like Microsoft's Majorana chip and IBM's quantum roadmap pointing toward thousands of qubits by 2033—still far from the millions needed but on a clear upward trajectory.
The Phased Approach to Quantum Migration
Bitcoin developers are taking proactive steps through a multi-phase plan:
- Phase One: Cease sending Bitcoin to vulnerable legacy addresses.
