Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Brazil, South America
People increasingly need trusted identity across migration, finance, education, health, and employment systems. The challenge is preventing fragmented credentials, exclusion, surveillance, and corporate dependency. Affected communities must have meaningful control over data, revenue, deployment decisions, and the right to refuse harmful applications. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Traditional credentials are too slow for rapidly changing technical work, while unverified short courses create noise. Future education needs trustworthy, modular, employer-connected, and worker-controlled skill validation. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

AI, automation, caregiving, health events, and climate disruptions may make stable employment less common. The challenge is designing benefits, credentials, insurance, and taxation systems that follow people across changing forms of work. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Fabricated reviewer identities, complete with fake credentials, have occasionally been used to manipulate the peer review process in favor of certain papers. Verifying reviewer authenticity more rigorously remains an unresolved challenge for academic publishing.

Attackers can automatically test massive numbers of previously leaked username and password combinations across many websites to find accounts where the same credentials still work. Reducing the effectiveness of this widespread technique remains an unresolved security challenge.

Tutoring platforms can be targeted by individuals using AI-generated fake credentials to appear more qualified than they actually are, and verification systems don't always catch this convincingly fabricated background information. Closing this trust gap remains an unresolved platform challenge.

Digital signatures can be technically valid while still being applied under coercion, fraud, or through compromised credentials, and current systems don't fully verify true signer intent. Closing this verification gap remains an unresolved legal-technical challenge.

Once login credentials are leaked in a breach, they often remain accessible and exploitable for attackers on illicit marketplaces for years afterward, long after the original breach was reported. Meaningfully reducing this lingering exposure remains unresolved.

AI can help generate convincing fake diplomas, transcripts, or certification documents, and verification systems haven't fully caught up with detecting these increasingly sophisticated forgeries. Closing this verification gap remains an unresolved challenge for employers and institutions.

When one website's user database is breached, attackers often successfully reuse those same stolen credentials on other unrelated websites where people reused the same password. Preventing this cascade of breaches remains an ongoing security challenge despite widespread password reuse warnings.

Entirely AI-generated academic theses can be difficult for reviewers to distinguish from genuine student work without specialized detection tools, and these tools remain imperfect. Protecting the integrity of academic credentials remains an ongoing unresolved challenge.

Developers still occasionally and accidentally commit sensitive credentials directly into shared code repositories, creating avoidable security exposure. More robust default protections against this common mistake remain inconsistently adopted.
