4 For PoW cryptos, the miners have to solve a math puzzle to verify the transaction. PoS cryptos attribute the mining power to the proportion of the coins held by the miners, instead of utilizing energy to solve math problems, in order to resolve the “wasted energy” problem of PoW. The PoI cryptos add a number of variables when attributing the mining power to nodes in order to resolve the “hoarding” problem that’s associated with PoS.

Earlier sections of this chapter talk about the basics of cryptocurrencies and how they’re related to blockchain technology. This section digs into other factors that make cryptocurrencies so special and different from government-backed legal tender, also known as fiat currency, such as the U.S. dollar.

Adaptive scaling is one of the advantages of investing in cryptocurrencies. It means that it gets harder to mine a specific cryptocurrency over time. It allows cryptocurrencies to work well on both small and large scales. That’s why cryptocurrencies take measures such as limiting the supply over time (to create scarcity) and reducing the reward for mining as more total coins are mined. Thanks to adaptive scaling, mining difficulty goes up and down depending on the popularity of the coin and the blockchain. This can give cryptocurrencies a real longevity within the market.
