DAICO

is a Decentralized Autonomous Organization whose goal is to manage Initial Coin Offerings (ICO).
It is a type of a smart contract that allows to "program" put conditions on the use of funds collected through ICO, including the possibility of refund to investors, if, for instance the milestones are not met.

The idea was proposed publicly by Buterin in early 2018 as a way to reign in the ICO's running wild in 2017. The first attempt at being implemented is being planned by gaming startup The Abyss.
