IBM experts have highlighted that the rise of quantum computing presents a more immediate threat to encrypted messaging applications like Signal and Threema than to Bitcoin. While the quantum threat to Bitcoin is often discussed, experts emphasize that messaging apps face a more direct risk from 'collect now, decrypt later' attacks. In such scenarios, attackers could intercept and store encrypted messages, decrypting them once quantum technology advances. In contrast, the Bitcoin network can be upgraded with quantum-resistant signature schemes to mitigate signature forgery risks. Signal has already implemented the PQXDH protocol upgrade, and Threema is collaborating with IBM to integrate the NIST-standard ML-KEM algorithm for quantum resistance.
