Quldra – A true device based post quantum messenger
by xMKx·Apr 29, 2026·2 points·2 comments
AI Analysis
●MidSlick
Another Signal clone claiming post-quantum security without independent audits.
Strengths
- •Device-bound keys prevent server-side identity theft better than phone numbers.
- •Guest browser sessions allow secure onboarding without forcing app installs.
Weaknesses
- •Proprietary protocol lacks the scrutiny that made Signal and Matrix trustworthy.
- •Post-quantum claims are marketing fluff until NIST standards are fully adopted.
