Decentralized Autonomous Organizations, known as DAOs, are controlled by their members and operate using rules encoded in computer-powered smart contracts. Two primary membership models exist within DAOs: token-based membership and share-based membership. Initially, tokens and shares were the primary means of voting rights. Currently, various DAO voting mechanisms are being proposed to maintain decentralized decision-making and encourage greater community involvement in governance processes.

Token-Based Quorum Voting Unveiled

Token-based quorum stands as one of the fundamental mechanisms for DAO voting. In this system, a set number of DAO members must engage in voting for a proposal to pass. If this threshold is met, the decision receiving the most votes prevails. Failing to reach the quorum results in the proposal being rejected. Despite aiming to stimulate member engagement and consider wider opinions, token-based quorum voting faces several challenges. Determining the appropriate quorum can be tricky. Requiring more members to vote might lead to low participation rates, causing numerous proposals to fail. Conversely, setting a low quorum poses the risk of passing proposals too easily, potentially steering the DAO in the wrong direction.

Encouraging participation proves to be a time-consuming and costly struggle for many DAOs. Some members may opt to stay inactive to obstruct a proposal or may simply lack interest in the decision-making process. Furthermore, this voting model intertwines financial standing with voting power, enabling members with more tokens to sway outcomes through manipulation or bribery, potentially politicizing the DAO voting process.

Insight into Permissioned Relative Majority

Within the permissioned relative majority DAO voting mechanism, the critical element lies in the count of 'for' and 'against' votes on a proposal. There is no minimum voting requirement, allowing even a single member to partake in decision-making. This system offers a straightforward and cost-effective voting process. However, it also grants excessive influence to individual members, potentially allowing them to dictate how DAO funds are managed. Moreover, the straightforward nature of this mechanism poses risks for proposals as they might pass too easily without sufficient scrutiny from other members.

To address these hurdles, proposing members can be mandated to secure sponsorship from other DAO members, a concept already explored by Moloch DAOs.

Introducing Rage Quitting as a Security Measure

Rage quitting emerges as a voting mechanism that harnesses sponsorship to enhance security within DAO voting decisions, potentially overcoming challenges seen in relative majority models. Prior to voting on a proposal, it must be sponsored by members. If the majority approves it, there is a grace period during which voters can retract their support from the vote or the DAO altogether. If adequate support is withdrawn post-grace period, the proposal is dismissed.

This mechanism serves to prevent majority voters from exerting undue influence over minority voters. However, the extended voting process might not be feasible for all DAOs due to its length.

Unraveling Quadratic Voting

Under the quadratic DAO voting model, voting power is directly proportional to financial power. Each member can cast multiple votes on a proposal, with the cost of each vote being the square of the number of votes desired. This system allows members to express strong beliefs on certain issues by investing more tokens. While this model addresses the risks of relative majority decision-making, there is a vulnerability to unfair results if fake identities partake in the voting process, underscoring the need for identity verification in quadratic voting.

Diving into Conviction Voting

Conviction voting emerges as a novel DAO voting mechanism, reliant on the community's aggregated preferences and leveraging time as a utility. Members can vote on ongoing proposals, with the strength of a vote increasing over time if it remains unchanged. However, modifications to the vote diminish its utility. This method provides insight into voter interest and influences on proposals, emphasizing community beliefs over majority decisions, thereby thwarting the rise of powerful new DAO members.

Despite its strengths, conviction voting demands significant time, making it unsuitable for time-sensitive decisions in certain DAOs. For broader adoption, combining this mechanism with a faster alternative might offer a more versatile approach.

Understanding Holographic Consensus

Holographic consensus DAO voting aims to predict which proposals are likely to pass in a DAO, focusing attention on those with higher chances of approval. By allowing members to predict the success or failure of proposals and betting tokens on their beliefs, this model aims to resolve governance scalability and resilience issues in decentralized organizations. While successful in enhancing scalability and fortifying defenses against misguided proposals, this voting protocol can be financially onerous and challenging to sustain in the long term.

Exploring Multisig Voting

Multisig voting seeks a balance between central authority and decentralization within DAOs. In this model, DAO members signal support on proposals while a centralized committee executes the voting process. This rapid mechanism is suited for urgent decision-making pivotal to a DAO's survival, although there remains a risk of centralized authorities abusing their power to the detriment of the broader DAO community.

Delving into Liquid Democracy

Liquid democracy, akin to vote delegation, borrows key principles from political democracy. In this setup, specialists are appointed to represent the electorate and make decisions on behalf of DAO members. While this mechanism leans towards centralization, members retain the authority to reassign delegation at any time, empowering them to choose new representatives. This approach enhances decision-making proficiency, yet similar to traditional political democracies, it remains vulnerable to manipulation through bribery and corruption.

Navigating the Evolution of DAO Voting

DAOs stand at a juncture of trial and error as various voting mechanisms are experimented with. While each model offers unique advantages tailored to specific DAO structures, ongoing challenges highlight the need for continuous refinement. As blockchain technology evolves and DAOs grow in prominence, we anticipate the emergence of innovative DAO voting mechanisms or the consolidation of existing models to develop more effective solutions.
