+In QUIC TLS handshake is absorbed into the initial setup handshake. HTTP/3 does not run TLS "on top" of QUIC. Instead, **TLS 1.3** is built into the QUIC protocol itself.
+QUIC mitigates HOL (Head of Line) problem by treating each stream within a single connection independently. If one particular frame is lost, QUIC will handle it separately without blocking the rest of the streams.
