@ntn-x2 I actually agree with you that adding the block number as part of the identifier makes things much more complicated and I also agree with your line of reasoning,...

Do I understand it right that we're looking for a terminal symbol suggesting hierarchy but that doesn't collide with existing standards like e.g. URI or URL?

Actually, I like what is discussed in #67, which is that fundamentally the concepts in e.g. CAIP-19 and so on are considered to be valid URIs or URNs. In that...

@ligi > but the colon would need to be escaped right? According to the BNF of RFC3686 on URI syntax (https://www.rfc-editor.org/rfc/rfc3986#appendix-A), the "hier-part" is allowed to include a "path-empty" that...

interesting, thanks for reporting. I think we may want to make this issue a priority

See #81.
