VisitBlockcerts vs CertSeal
What both publish
| Fact | Blockcerts | CertSeal |
|---|---|---|
| Privacy | The FAQ says the blockchain stores a one-way hash of certificate data, from which the original data cannot feasibly be recovered. | CertSeal says it can sign a DPA covering GDPR, UK GDPR, and Singapore's PDPA. |
| Revocation | The standard supports issuer revocation, including Open Badges-style HTTP revocation lists and other schema-dependent methods. | Revocation and re-issuance are available for correcting or invalidating previously sent credentials. |
| Self-hosting | Developers can run the verifier locally and build the cert-issuer Docker image for experimentation or deployment. | On-premises deployment is listed only as a Custom-plan option. |
