There are still credit bureaus, and things like defaults, judgements, etc are recorded, and when you apply for credit this is checked.
However there are crucial differences to a score system like the UK and (I assume) the US - there is no 'building good credit', you don't get any benefit from having existing credit products and using them well. In fact the opposite - having other forms of credit like a credit card available is seen as a negative when you apply for a mortgage and will impact the amount you can get loaned. They'll literally knock the credit card limit off the top of the mortgage offer.
