Tally sticks are the oldest form of controlling the stability of exchange. In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless updating the oldest measure to tangible measure. The split of bitcoin mining rewards from 25 to 12.5 BTC illustrated by tally sticks is to signify one of the biggest engines of it: FOMO.
