Can you point me to any paper (other than the Satoshi paper) that describes an immutable distributed ledger and it's implementation?

If there was no new economics in Bitcoin, can you explain why the paper would be nominated for Nobel Prize for Economics in the first place? https://bitcoinmagazine.com/articles/satoshi-nakamoto-nomina...

It's quite clear that the nomination was rejected on flimsy grounds of not awarding the Prize for "unknown people" because there is no such "precedence".
