Blockchain lookalike domains
Greyphish has recorded 826 domains that resemble Blockchain since February 2026, 142 of them in the last 90 days. Most of them (70%) are combosquats: Blockchain spelled correctly with a word added, most often “support”, “app”, “service”. .com carries 48% of them, out of 101 endings in all. The pace has picked up, with 70 in the last 30 days against 28 in the 30 before. The busiest week began 5 October 2026, with 38 new ones. 30 certificates for unregistered .ph, .com.ph, .net.ph names (registry wildcard) are excluded: the registry answers for any name under those endings, so nobody had to register one to get a certificate for it.

Where they are registered
For the 451 with a registrar in WHOIS (55% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.

|---|---|---|---|
| Dynadot | 160 | 35.5% | Retail |
| GoDaddy | 68 | 15.1% | Retail |
