Mini-Heap describes this post under the heading 'the metaphysics of blockchain'. It's a good title. The main idea here is that blockchain for Bitcoin works because the record is the fact. But for something like, say, a birth date, the fact exists independently of the record, and the same sort of transcription errors that can make birth certificates unreliable can also infect the blockchain record. But what about, say, badges, credentials and other educational records? Is an educational record a recording of a real world event, or is the production of the record the event in itself? After all, when the program is complete, nothing actually exists over and above the record.
