Charles Hoskinson, founder of Cardano and CEO of IOHK, recently said that the difference between PoS and PoW is obvious: one is physical and the other is to reduce input to generate equivalent output. In the long run, PoW is not feasible because the mine pool is not loyal and the members of the pool “do not care about the price of the currency or the chain”. For the Cardano 1.5 release launched last month, Hoskinson said the upgrade was one of a series of updates that pushed the Cardano network to become more central. He claims that after completing a series of upgrades, users will receive cryptocurrencies that are 100 times more decentralized than Bitcoin. In 2019, the Cardano network will decentralize more than any other network in the encryption market.
