This is usually achieved by associating the URI with a specific blockchain address or identifier. The uniqueness validation standard helps prevent  duplicate or incorrect identifiers, ensuring the accuracy of data and transactions. Generally, the uniqueness validation standard for URI also includes checking whether the URI conforms to the predetermined naming rules and structure, as well as ensuring that its associated relationship with related entities (such as projects, assets, individuals, etc.) is clear and explicit."}]}],"pr":"83f5e730dd5bce0a5f8a606df4feca554c2a92e5c65ced6541a9da99b669388b"}
