Winnable issues: Case study examples

Use Case 1: Safe Communication for Survivors of Domestic Abuse in Lisbon

In collaboration with local organisation: https://apav.pt/

Local Context:

Many domestic violence survivors avoid seeking help because digital channels are monitored by abusers, or their identities could be exposed through centralised platforms.

Downstream Application of Logos Tech:

• Privacy-preserving Messaging (Waku):

  Deploy an anonymous messaging app that routes through a decentralised network with zero data retention. Survivors can connect securely with caseworkers, shelters, or peer support groups. Hide the app behind a different logo on the users’ device.

• On-chain Identity & Access:

  Use pseudonymous credentials to give verified support providers access to sensitive conversations with full consent from the user while keeping identity off-chain.

• Reputation-Based Systems:

  Build a reputation layer that allows survivors to review and recommend safe services and professionals without exposing themselves publicly.

Impact:

A digital lifeline for at-risk individuals, created in collaboration with frontline workers and shaped by direct experience. Builds trust between communities and Logos while demonstrating tech that solves real problems.

OR: Circle community-funded wallet to help support people leaving that situation.

Use Case 2 : Air Pollution in Peshawar

Local Context:

Peshawar suffers from extreme air pollution due to traffic, industrial emissions, and urban development. Residents face daily health risks, especially children and the elderly. Public monitoring and enforcement are limited, leaving communities without actionable information.

Circle actions using the Logos technology stack:

• Deploy community sensors (Waku + Codex):

  Circle members can install low-cost, open-source air quality sensors in neighbourhoods. Data is stored securely in Codex and communicated via Waku, giving residents verifiable, real-time access.

• Community alerts and education:

  Circles can send real-time alerts when air quality spikes, organise awareness campaigns, or publish safe practices for families, schools, and workplaces.

• Micro interventions and prototypes:

  Using locally available skills, Circles could build:

  • Green buffers (planting trees or vertical gardens) in hotspots.

  • DIY air purifiers for home, schools, clinics ect.

  • Community-led campaigns for reduced vehicle idling or industrial compliance.

• Data-driven advocacy:

  Aggregated sensor data and documented interventions can be presented to local authorities or NGOs like Pakistan Environmental Protection Society (PEPS**)** to push for policy changes, funding, or enforcement support.

Impact:

Empowers residents to take direct action instead of waiting for government intervention while providing tangible improvements to neighbourhood air quality through both behaviour change and micro-projects. It demonstrates the potential of decentralised governance and tech-enabled community solutions to address critical public goods.
