I think the term that should be used is NOT blockchain, but distributed ledger technology. From my limited point of view reading your article you sure have a functional- and not a technical problem today. If it makes sense using public ledgers with blockchain technology depends how you tackle security issues, because one thing is clear:
- Cryptocurrencies are secure because of their vast computing power you can’t hardly out compete to fake blocks and all participants mining are getting rewards out of it (they are providing the computing power)
If you can do this in the music sector with a public ledger I’m all ears to hear that solution out.
