Public Goods Technology

Easy

Public goods technology is digital infrastructure that is open, shared, and designed to serve broad public benefit.

What Is Public Goods Technology?

Public goods technology is digital infrastructure that is open, shared, and designed to serve broad public benefit. 

These technologies are generally built to support digital inclusion, user privacy, financial access, and public participation. 

Building public goods onchain can serve the public by supporting user privacy, financial independence, and self-determination, with features such as permissionless transactions and censorship-resistant data layers.

What Is the Difference Between “Can’t Be Evil” and “Don’t Be Evil” Architecture?

“Don’t be evil” architecture asks users to trust a company or platform, while “can’t be evil” architecture uses code to limit what anyone can do.

Technologies are tools that reflect the intentions and values of the people or groups that operate them. To avoid exploitation of a platform or technology by a single party, core principles can be built directly into the technology’s design. This is called “can’t be evil” architecture.

Traditional approaches to censorship resistance, data protection, and user privacy generally rely on policy compliance rather than technical enforcement. This is called a “don't be evil” approach that relies on corporate goodwill. Even with regulation, users’ rights can be difficult to protect if one company or platform controls the system.

Unlike traditional “don't be evil” approaches, public goods technology makes actions that are potentially harmful to the end user either unprofitable or impossible through protocol design. For example, transaction fees can discourage spam by making mass unsolicited messages too expensive, without relying on a gatekeeper to police behavior.
“Can’t be evil” design can also protect privacy, independence, or accessibility by default. For example, zero-knowledge proofs can help users prove something is true without revealing private information.

What Are Real-World Applications for Public Goods Technologies?

Public goods technology can support funding systems, wireless networks, open-source tools, and low-cost payment networks.
One example is quadratic funding, a model that helps direct funding toward projects with broad community support. For instance, a project backed by 200 people giving $1 each can receive more matching support than a project backed by one person giving $500. Blockchain can support this model by making contributions publicly verifiable onchain. The matching algorithm can also run autonomously, reducing the need for a trusted third party to control the funds. 
Blockchain can also support infrastructure for new kinds of physical networks. Decentralized physical infrastructure networks, or DePINs, use token incentives to crowdsource real-world infrastructure. For example, individuals can deploy wireless hotspots in their homes and communities, earning tokens for the connectivity they provide. The result is a community-run wireless network that does not rely on a central telecom provider.

Finance is another major use case. Open payment networks can make transfers cheaper and more accessible, especially for users who lack reliable access to banks. 

How Can Public Goods Technology Balance Adoption and Values?

Public goods technology must protect users while still being simple enough for ordinary people to use.

The goal is to create digital infrastructure where only actions benefiting the ecosystem are viable, ensuring the system remains accessible and resistant to capture by special interests. However, this does not always translate into an easy experience for end users. 

Many systems that protect user rights also add complexity. Simplifying these systems can make them easier to use, but it may also require users to give up some control, transparency, or autonomy.

This helps explain the limited uptake of traditional public goods technologies like Linux or the Tor browser. Both are powerful tools, but unfamiliar UX and technical requirements may keep them out of reach for some people. 

This can be remedied by treating usability as part of the technology’s values. Infrastructure that is technically free but practically unusable still fails many of the communities it was built to serve. The most durable public goods technologies treat accessibility as a design requirement, not an afterthought.

What Is Public-Good Washing?

Public good washing is when a project calls itself a public good without building openness, user protection, or shared benefit into its design.

For example, a project may use the term “public good” in marketing to suggest that it has broad utility, even when its architecture does not reflect public good values. This has led some developers to simply call their projects “open source,” meaning the code is available for others to use, inspect, or build on.

A project is more likely to be a true public good if it:

  • Makes bad faith actions either technically impossible or economically unviable by design.

  • Is open to all and not depleted by use.

  • Builds user and ecosystem protections into its architecture, reducing the risk that it can be captured, censored, or exploited by one dominant party.
