When the topic of blockchain evolution and decentralized governance is being discussed, one of the terms that has received a lot of attention is DAO in crypto. DAO stands for Decentralized Autonomous Organization, which is an open community structure in which rules are programmed on the blockchain by means of smart contracts and decisions are made by its members in consensus, as opposed to a governing authority. While the world of crypto is growing up, DAOs have branched out into various forms, each with its own uses and testing of governance mechanisms. Knowing these types not only makes us aware of the variance of the crypto universe but also brings to light how decentralized governance is changing businesses.
