So other accounting software provides mutable ? Square are you serious? Just adding a authentication layer over it and calling immutable

I don’t think you quite understand what they are doing. Once the entry is in the ledger, it can’t be changed. To correct it you must add in a compensating transaction that corrects the transaction - almost certainly a reversal.

Basically, it’s just a list of transactions you can only append to. You can’t delete any of the entries or modify them - they really are immutable.
