Why Do On-Chain Credentials Raise Privacy Concerns For DAOs?

Decentralized Autonomous Organizations (DAOs) are designed to be transparent, trusting, and open to participation. In order to facilitate such values, DAOs make extensive use of on-chain credentials, which refer to blockchain-based verifiable evidence of identity, contribution, or reputation. Such credentials are useful for secure and trustworthy DAOs but raise significant concerns about the privacy of DAO members.

In essence, a blockchain is immutable and public. Once credentials are placed on a blockchain, they become visible, accessible, and traceable to wallet actions. This scenario raises a pivotal question regarding the future of Decentralized Governance: What is the privacy concern of on-chain credentials to members of a DAO, and implications for future autonomy?

The article examines the Privacy Trade-offs of On-chain Credentials in crypto DAOs and the risks and challenges involved. The article further investigates the numerous solutions being developed that can ensure the Privacy of individuals involved.

Understanding On-Chain Credentials in DAOs

On-chain credentials are the attestations that are provided on the blockchain with regards to certain aspects of the DAO participant that are verified on the blockchain. These are commonly utilized for:

• Prove DAO membership

• Define voting rights

• Check contributions made previously

• Signal reputation or expertise

In contrast to traditional credentials stored in private databases, an on-chain credential is publicly verifiable and tamper-proof. This is very appealing for decentralized systems, where trust in central authorities is limited or non-existent.

However, it should be noted that these are the same properties which make on-chain credentials secure, and yet these properties are what create privacy issues.

Why DAOs Are Embracing On-Blockchain Credentials

DAOs make use of on-chain credentials in order to provide a solution for real-world governance issues. Among the advantages include:

• Sybil resistance: Coping with imitation identities

• Merit-based governance: Vote weighting based on contribution

• Automation: Implementing self-executing rights for smart contracts

• Auditability: It should be possible for anyone to trace and audit

These benefits have contributed to the rapid adoption of credential-based DAO systems. However, as adoption escalates, associated privacy concerns also rise.

Core Privacy Issues in On-Chain Credentials

1. Permanent Public Visibility

Blockchains are made to be transparent and immutable. Once the credentials are recorded on-chain, the following take place:

• They cannot be deleted or altered

• They are visible for an indefinite

• They can be analyzed retrospectively by anyone

This is a permanent outcome, which means that even if a DAO participant changes their mind or their situation, their actions or relationships in the past might forever remain accessible through the DAO.

2. Linkability of Identity & Behaviour

Even if the credential information does not explicitly contain personal details, it may nevertheless be traceable to the addresses on wallets. Over time, the following correlations are able to be made:

• Voting Patterns

• Financial transactions

• DAO memberships

• Contribution histories

This enables the generation of refined behavioral patterns for the participants that can jeopardize the anonymity which is basically expected within such decentralized networks.

3. Loss of Context Over Time

On-chain credentials capture facts but not context. Example:

• The vote might have been cast years ago, which no longer reflects what a person currently believes.

• A donation given under different circumstances may be misunderstood.

• Temporary roles may be made to appear permanent

Because credentials are immutable, often participants cannot easily update or contextualize past records, with all the reputational risk that brings.

4. Chilling Effect on Participation

More than that, the question of privacy may turn away enthusiasm for DAOs in general, but especially with:

• Political sensitive DAOs

• DAOs operating across jurisdictions

• Governance involving controversial decisions

Fearing long-term exposure of on-chain credentials may result in participants self-censoring themselves or avoiding any governance roles altogether.

5. Credential Exploitation Risk

Public credentials may be used in ways that are unintended, for example:

• Targeted phishing or social engineering

• Doxing, blacklisting, or discrimination across DAOs

• Third-party surveillance

This becomes increasingly important as DAOs interlink, providing potential credentials in one context that impact opportunities in another.

The Role of the Soulbound Token in Credential Design

A rising number of DAOs is experimenting with Soulbound Tokens as a means to represent non-transactable credentials, such as reputation, membership, or achievements.

Soulbound Tokens are designed to be permanently bound to a wallet, which makes them useful for governance and identity, but they also increase the intensity of privacy concerns by:

• They improve permanence and traceability.

• Complicated to revoke or anonymize

• They are capable of storing sensitive historical data over time.

While Soulbound Tokens are meant to reinforce decentralized identity, careful consideration in implementation should be directed towards privacy-preserving mechanisms to avoid long-term exposure to participants.
