When Adam sold the property to Dave in 1930. a new entry was made in the ledger, and so on.

A cryptographic puzzle must be solved, thus creating the block.

The computer that solves the puzzle shares the solution to all the other computer on the network.The is called proof-of-work. 

The network verifies the proof-of-work.
