Introduction
Cryptocurrency systems are often described as 'trustless,' meaning they operate without relying on trusted intermediaries to enforce rules. However, trust itself is not entirely eliminated—instead, it shifts to the social layer of people and organizations responsible for defining and maintaining these protocols. This raises a critical question: how can we ensure this social layer remains trustworthy to sustain confidence in the system? This article explores the dynamics of trust at scale, the role of crypto systems as confidence machines, and the importance of building trustworthy communities.
How Trust Operates at Scale
Aligning Trust With Trustworthiness
Trust is fundamental to human cooperation and societal function. Rather than blindly increasing trust, we need effective methods to assess trustworthiness. This involves evaluating evidence of reliability, honesty, and competence while considering the risks of misplacing trust. We rely on cognitive shortcuts and societal pressures—such as appearance, identity, morals, and reputation—to make these assessments quickly.
Morals and Reputation
Morals facilitate trust in small-scale interactions like families and local communities. Face-to-face communication allows us to intuitively gauge honesty through body language, emotional cues, and coherence in speech. Reputation serves as a social identity shaped by group opinions, often communicated through gossip or rumors. It reinforces social norms and status within communities.
Institutional Trust
As communities grow into cities and societies, morals and reputation alone become insufficient. We codify values into formal institutions and legal systems. We trust strangers indirectly by trusting the institutions that regulate their behavior. For example, hailing a taxi involves trust in the licensing authority, the driving certification agency, and the company brand—not just the individual driver.
Solving the Principal-Agent Problem
Institutions create intermediaries (agents) to implement rules. Trust depends on aligning the agent's interests with those of the principal (us). Transparency alone is inadequate; evidence must be comprehensible and verifiable. We often rely on experts, auditors, or rating systems to assess trustworthiness. Ultimately, shared values and visions ensure genuine alignment of interests.
Security Systems
Where institutions reach their limits, security systems embed behavioral rules directly into hardware and software. Zero-knowledge proofs (ZKPs), for instance, enable verification without revealing underlying data. This is powerful for privacy-sensitive contexts where mutual trust is absent.

Mina Protocol's 'httpz vision' aims to create an internet where people can generate and verify proofs of information. While HTTPS secures data exchange via encryption and certificate authorities, adding a ZKP layer allows verification without trusting any central authority.
Crypto Systems as New Institutions
The Rise of Trustless Systems
The 2008 financial crisis eroded trust in traditional institutions. In response, blockchain technology enabled new economic systems that operate without trusted intermediaries. These systems are 'trustless' because they enforce rules algorithmically rather than through human intermediaries.
Confidence Machines
Crypto systems function as confidence machines. Transactions execute reliably due to cryptographic primitives, deterministic computing, and distributed consensus. This confidence stems from past experiences, general knowledge, and expert validation of the technology's predictability.
The Social Layer of Technology
Trustlessness doesn't eliminate trust—it redistributes it to the social layer: the people and organizations designing, implementing, and maintaining the system. If "code is law," then we must trust those who write the code. Confidence in the protocol depends on trust in the political institutions governing its rules.
Case Study: The UST and LUNA Crash
Crises reveal assumptions and flaws in systems. The 2022 collapse of Terra's UST stablecoin and LUNA token highlights the importance of the social layer.
Assumed Stability
Terraform Labs created UST, an algorithmic stablecoin pegged to the USD, using LUNA to absorb volatility. Despite assumptions of stability, UST lost its peg, triggering a crash that erased $60 billion in value within a week and wiped $1 trillion from the global crypto market.
Trust in the Social Layer
Research interviewing affected community members revealed:
- Ideologically motivated participants struggled to find meaning post-crash, while financially motivated ones focused on risk awareness.
- All experienced negative emotions, including distrust and loss of control. They sought support from high-reputation community figures.
- Co-founder Do Kwon became a focal point, with followers awaiting his guidance via Twitter to navigate the crisis.
This case underscores how trust in the social layer underpins confidence in the protocol.
Can Trustworthiness Offer Competitive Advantage?
Reduced trust in the social layer erodes protocol confidence, discouraging participation and potentially dissolving communities. Conversely, demonstrating trustworthiness could provide a competitive edge.
Principles for Trustworthy Institutions
Key principles include:
- Transparency: Providing evidence of reliability, honesty, and competence.
- Comprehensibility: Ensuring evidence is accessible and understandable.
- Verifiability: Enabling validation of truthfulness.
- Shared Values: Aligning interests through common goals and visions.
Mina Protocol aims to implement these principles in its governance, setting an example for how crypto institutions can be designed and managed trustworthily.

Frequently Asked Questions
What does 'trustless' mean in crypto?
Trustless systems operate without trusted intermediaries by enforcing rules through code and consensus. However, trust is still placed in the social layer that creates and maintains the protocol.
How can we assess trustworthiness in crypto projects?
Look for transparency in operations, comprehensible evidence of reliability, verifiable data, and alignment of values with the community. Audits, community reviews, and expert assessments also help.
Why did Terra's UST stablecoin fail?
UST collapsed due to a loss of peg to the USD, exacerbated by algorithmic design flaws and a crisis of confidence in the social layer, including leadership and community trust.
What role do zero-knowledge proofs play in trust?
ZKPs allow verification of data without revealing its content, enhancing privacy and reducing the need for trust in intermediaries. They enable secure, private interactions in untrusted environments.
How can crypto communities build trust?
By fostering transparency, enabling community participation in governance, providing verifiable evidence of actions, and aligning project goals with community values.
What is Mina Protocol's approach to trust?
Mina emphasizes lightweight blockchain design using ZKPs, with governance principles focused on transparency, comprehensibility, verifiability, and shared values to build a trustworthy ecosystem.
Conclusion
Trust remains a cornerstone of crypto systems, shifted from intermediaries to the social layer. Building trustworthy communities requires transparency, comprehensibility, verifiability, and shared values. Projects that demonstrate these qualities may gain a competitive advantage by fostering confidence and engagement. Mina Protocol's governance initiatives offer a promising model for how crypto institutions can achieve trustworthiness at scale.
