Today, the Institute of General Studies in the latest report pointed out that the early PoS consensus faced a "no interest" crisis, and the blockchain was easy to fork. The "Slasher" mechanism adopted by Ethereum Casper and Cosmos solves the previous PoS consensus of non-interested attacks by adding penalties to dishonest nodes. The “equity economy” represented by PoS is an economic system different from the PoW consensus. Generally, the economic model of inflation is adopted. Only the mortgage pass can participate in the network consensus process to obtain interest income. The miser strategy of “holding the currency to go up” no longer applies to the new PoS consensus, all holders must participate in the network consensus process, and there will be more financial application scenarios based on this demand.
