Decentralized autonomous organization Compound, Uniswap and Ethereum name service (ENS). In particular, we examine how the voting power is

addresses, we rarely observe these powerful entities overturning a vote by choosing a different outcome than
that of the overall community and less influential voters.

Voting systems similar to those currently used by many DAOs have
a long history of academic discussion. They are commonly referred to
as delegative democracy[18]or liquid democracy[1,8]. The governance

a main difference being that they only allow for voting rights to be

6. Address clustering
During all the analyses, it is important to keep in mind that multiple
addresses—holder as well as delegate addresses—can be controlled by
the same entity. This fact can make it challenging to determine the
actual distribution of power in a governance system and can lead to the
illusion of greater decentralization in the system than what truly exists.
Moreover, the situations of a single entity controlling multiple ad-
dresses are actuallyfavored by the design of the delegation rules of the
governance systems: It is only possible for a token holder to delegate all
of their tokens to a single address. A token holder wishing to delegate
to multiple delegates must split their tokens across multiple addresses
