Merkle Tree Certificates pilot by Cloudflare and Chrome

🔐 Cloudflare is collaborating with Chrome to experimentally deploy Merkle Tree Certificates (MTCs) to reduce the number of public keys and large post-quantum signatures transmitted during TLS handshakes. MTCs batch certificates into a Merkle tree with a single signed treehead and per-certificate inclusion proofs, dramatically shrinking handshake size and CPU work. The experiment will roll out to a subset of Cloudflare free customers while Chrome distributes validation landmarks and fallbacks to preserve existing trust.
