The incentives mechanism

Now, why should every villager try to find number X since somebody is going to find it anyway and tell everyone else? Why should a villager spend time and effort to have his/her page validated and displayed on the wall?

We introduce here the incentive mechanism, an economic payoff for the community to play fair. Because the pages should keep being sealed to keep the transactions accurate, the community should continuously work on solving the mathematical problem. In this manner, a reward is given to the villager who finds number X, that is, the first villager to find the correct hash of the page. In our example, Dan is rewarded with, say, 5 Villagecoin. 

This incentive mechanism ensures that everyone keeps interested in working for the common good. More on that in Chapter 2, A Technical Dive into Blockchain.

Now that page #1 is displayed on the wall and secured, transactions continue to take place: Chuck sends 5 Villagecoin to Alice, Dan sends 2 Villagecoin to Bob, and so on.

When page #2 is completed with 10 transactions, the villagers repeat the entire process all over again.
