EBSI
EBSI, the European Blockchain Services Infrastructure, is a network of nodes run by EU member states and the European Commission that anchors cross-border trust for verifiable credentials, such as which issuers and schemas are recognised, without relying on a single central registry.
A relying party or wallet can check EBSI to confirm that a credential schema or an issuer is registered, the same way a Trusted List answers that question under eIDAS 2.0, but for a wider set of use cases than the regulation alone covers, including diplomas, business credentials and self-sovereign identity pilots run before eIDAS 2.0 existed. It predates the EUDI Wallet and its trust framework, and several EUDI Wallet pilots, including FIDES Community e-invoicing and business-identity work, use EBSI as their trust registry today.
