Make domain verification as easy as verifying an email or phone number
Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]). The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (think email, telephone, DID), enabling anyone that can prove…

Domain Verification is a protocol that simplifies proving control over a domain by storing a DNS TXT record at a location derived from a hashed identifier like an email address or phone number. Instead of manually pasting verification strings into DNS records at various provider-specified locations, users can prove domain authority through identifiers they already control. This approach works similarly to email or phone verification and removes inconsistencies between different providers' verification methods.

Email Validator by SidemailFeb 2026 · sidemail.io · ▲16Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you. What it checks: - Syntax – Confirms correct proper email format. - Domain & DNS – Verifies the domain exists and resolves. - MX records – Verifies the domain can receive mail. - SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent). - Disposable domains – Flags temporary inbox providers that can hurt deliverability lists. - Common typos – Catches mistakes and suggests fixes. How it works: Paste an email > click Validate > get a clear result with…
