Let's Encrypt Unveils Quantum-Safe Merkle Tree Certificates Roadmap!

Let's Encrypt has announced its transition to Merkle Tree Certificates (MTCs) for post-quantum security, targeting a staging release by late 2026. This innovative approach significantly reduces the handshake size, overcoming issues seen with traditional post-quantum signatures. Major browsers and companies like Google are backing the initiative, crucial for preparing against emerging quantum threats. The full rollout is expected by 2027.
