In the world of cryptocurrency or cryptocurrency, an instrument known as ICO (Initial Coin Offering) is used to finance the development of new protocols. This expression, literally translated into Spanish, means Initial Offer of Currency.
There are two main mining methods, Proof of Work (PoW) and Proof of Stake (PoS), which are relevant for us to understand how an ICO works. On the one hand, the Proof of Work mining model is used in the Bitcoin, Litecoin or Ethereum protocol to mention only a few examples.
The Proof of Stake is a model in which the owners of cryptocurrencies are progressively rewarded - in a lottery among the cryptocurrency holders themselves - with new tokens of the same type. In this model, holders of more units of account or currencies are more likely to increase their holdings with new cryptocurrencies.
The Proof of Stake model, unlike the Proof of Work model, allows a distribution of cryptocurrencies or tokens based exclusively on the priorities of the protocol developers, a circumstance that has allowed the creation of ICOs with a fraudulent or dishonest tone. The advantage of the PoS system is that it does not consume energy to ensure the system unlike the Work Test model, but unlike the PoW the distribution of the coins can be unbalanced.
