In WebTransport, the serverCertificateHashes option allows the website to connect to a WebTransport server by authenticating the certificate against the expected certificate hash instead of using the Web public key infrastructure (PKI). This feature allows Web developers to connect to WebTransport servers that would normally find obtaining a publicly trusted certificate challenging, such as hosts that are not publically routable, or virtual machines that are ephemeral in nature.
