Verifiable credentials are becoming a reality, and more and more governments are adopting them for the digital identity of their citizens and the registries of their businesses. The question that defines everything else is not whether to adopt them, but on what infrastructure to deploy them.
When digital identity is deployed on a proprietary platform, every service keeps its own copy of the citizen's identity and of the business record. Nothing interoperates outside the platform, license costs climb, and the technology decisions no longer belong to the State but to the vendor.
Vendor lock-in is not just a technical problem. It is a cession of sovereignty: whoever controls the platform controls the rules, the data, and the continuity of the service.
