# Swearlt - Transparency of Cleaning Measures

> Swearlt is a blockchain-based system for transparent documentation of cleaning measures in public spaces. The system enables companies to immutably document every cleaning step in the blockchain and provide consumers with real-time insight into performed hygiene measures via QR codes. This strengthens trust among users of public spaces, especially after the COVID-19 pandemic.

## Description

The Federal Institute for Occupational Safety and Health (BAuA) analysed the application potentials of blockchain for various work areas, including documentation of service delivery such as cleaning services, in the publication Blockchain Technology: Opportunities and Risks.

Cleaning companies face a fundamental problem: How can they prove that cleaning actually took place and was carried out to the required quality? Current approaches: timesheets (manual, falsifiable), on-site QR code scans (easy to circumvent), supervisors (expensive, poor scalability). Blockchain solution: cleaners use an app that records the location upon entering the cleaning area and creates a blockchain entry; IoT sensors can detect cleaning activities (vacuum cleaner switched on, mop trolley moved) and document them directly on-chain; the client sees in real time what was cleaned and when. Performance-based billing: instead of per hour, billing can be based on actually performed, blockchain-verified cleaning units. Particularly relevant: hospital hygiene (infection prevention), food businesses (HACCP documentation), public facilities (accountability requirements).

## Benefits

- Cleaning companies can charge premium prices for demonstrably transparent and high-quality services.
- Consumers receive real-time information about hygiene measures and can make informed decisions about using public spaces.
- The system builds trust through transparent and traceable documentation of all cleaning measures.
- Companies can position themselves as hygiene-conscious and technologically advanced providers.
- Automated documentation reduces administrative effort and minimises sources of error.
- Digital documentation can contribute to professionalisation and better appreciation of cleaning work.

## Challenges

- Companies must invest in new technology and staff training without a clearly measurable ROI.
- Implementation requires extensive training of staff in handling the new technology.
- Possible security vulnerabilities in the blockchain platform or system failures could affect documentation.
- Cleaning staff might resist the additional digital documentation that changes their daily work.

## Technology foundation

The system uses blockchain technology for immutable storage of cleaning data, excluding manipulation. The type of blockchain used is not specified but could be a private or permissioned blockchain to control access to sensitive operational data.
