In collaboration with Ethereum co-founder Vitalik Buterin, Cornell University researchers are exploring new measures to protect decentralized autonomous organizations (DAOs) from emerging threats. As DAOs gain prominence, they face increasing risks, particularly vote-buying attacks, which could compromise their decentralised nature.
DAOs enable communities to make collective decisions without central oversight, but their popularity has attracted malicious actors who could exploit the system. Vote-buying attacks, where individuals are bribed to sway decisions, pose a significant threat. Buterin and other researchers have introduced a novel solution to mitigate this risk.
Buterin proposes PoCK to combat vote-buying
The threat of vote-buying in DAOs stems from the voting mechanism granting token holders power. While this approach promotes decentralised governance, it is vulnerable to manipulation. Bad actors can financially incentivise voters to support specific proposals, undermining the integrity of the process.
Detecting and preventing such attacks in a decentralised environment is challenging. The anonymity afforded by blockchain technology further complicates efforts to identify perpetrators. To address these challenges, Buterin and his team have proposed the concept of Proof of Complete Knowledge (PoCK). This mechanism ensures that voters genuinely possess and control their keys, preventing manipulation by external parties.

PoCK safeguards against attackers using trusted execution environments (TEEs) or application-specific integrated circuits (ASICs). By verifying that voters have complete control over their keys, PoCK strengthens the security and integrity of DAO governance. This innovation marks a significant step toward protecting DAOs from vote-buying attacks.
Recent DAO attacks highlight security vulnerabilities
The recent incident involving Compound DAO underscores the vulnerabilities within decentralised governance systems. A group known as the Golden Boys exploited low voter participation and conflicting interests to push through a proposal that benefited them financially. This event is a stark reminder of the need for robust security measures in DAOs.
Researchers at the University Complutense of Madrid revealed that half of all DAOs have fewer than ten active voters. Additionally, less than 30% of DAO members participate in the governance process for the majority of proposals. Alarmingly, less than 1% of members control over 50% of the voting power. These factors create opportunities for entities with substantial resources to influence and manipulate the governance process.
The attack on Compound’s DAO may have been an inevitable outcome of low participation and the inherent vulnerabilities in DAO structures. The development of PoCK offers a promising solution to these challenges, although it is still in its early stages.
The path forward for DAO security
As DAOs grow in popularity, ensuring their security and integrity is paramount. Vitalik Buterin and the Cornell research team’s work represents a critical advancement in safeguarding decentralized governance. Addressing the threat of vote manipulation through innovations like PoCK makes the future of DAOs more secure.
The ongoing research and development in this area will be crucial for the success of DAOs. Protecting these organisations from vote-buying attacks and other vulnerabilities will be essential for their continued growth and adoption in the broader decentralised ecosystem.
