00:00so now you can see that these two inventions solved the problems that the villagers had
00:04however there's a big difference between these two inventions the ledger is a record book that
00:09records all the transactions and the crypt are the actual coins that the villagers use
00:14in other words the ledger is the system that keeps track of all the crypt so the professor
00:19said to the mayor hey you can use the ledger to keep track of all the crypts the mayor was
00:25like
00:25really wow that's amazing then the professor said wait hold on you can't actually use the ledger
00:32without the crypt the mayor was confused so the professor explained it to him he said think about
00:37it if you want to keep track of the crypts you need to have a record of all the transactions
00:41that
00:41happened with them for example how many crypt does alice have how many crypt does bob have and you
00:47also need to know who owns which crypt right the mayor said yeah of course then the professor
00:53continued well that's exactly what the ledger does it keeps track of all the crypt and all the
00:59transactions that happen with them the mayor said oh i get it now so without the crypt the ledger
01:05wouldn't really have a purpose the professor said exactly you see the ledger is just a record book that
01:11records all the transactions that happen with the crypt so you can't use one without the other
