[ndnSIM] integrate blockchain with NDN

[Lixia Zhang]

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.
