Message-ID: <34EBB6A6-1849-439C-8530-82FB15E1F1C2@cs.ucla.edu> 1/ as I explained earlier, I prefer to call permission based immutable ledger as ledger, not blockchain (which is reserved to mean anonymous ledger) 2/ as the name stated, immutable ledger is just that, an immutable ledger. Immutability alone does not serve the purpose of authentication nor authorization (managing resources). An immutable ledger can store *authenticated* data/content, ensuring that they cannot be deleted.
