Common solution with existing precinct tabulators: each voter is issued both an anonymous ballot and a permit with identifying information. After marking the ballot, the ballot is inserted into the tabulator and the permit is retained in a file with the tabulator. At the end of each day, the number of votes recorded by the tabulator should match the number of permits, which contain the identifying information and so can be audited against the pollbooks. This same model can be extended to the blockchain approach, but isn't using a blockchain to solve the ballot-stuffing problem - just using a conventional paper technique.
