The book goes over the history of human transactions from hunter gatherer to modern day and how currency or a ‘ledger’ has played a role in those transactions as civilization has progressed.

The topic of inflation for hundreds of years and currency debasement is covered in detail and a common theme throughout the entire book.

Overall I’d recommend the book, Lyn is a great writer. The end is definitely Bitcoin heavy but I still enjoyed it ( I do not own any cryptocurrency ).
