# Hyperledger Fabric Blockchain Installation for CRM Data Protection

> ECOPLAN GmbH developed an automated installation tool for Hyperledger Fabric to secure CRM data. The project was funded with 52,047 euros by LIDIA-Hessen from September 2022 to October 2023 and published as an open-source solution on GitHub. The tool enables small and medium-sized enterprises to implement blockchain technology for CRM data protection without deep technical expertise.

## Description

ECOPLAN GmbH (Frankfurt), in cooperation with LIDIA-Hessen (State Initiative Digital Infrastructures Hessen), conducted a feasibility study on using Hyperledger Fabric for tamper-proof CRM data storage. The resulting open-source project (Blockchain Installer) was published on GitHub.

CRM systems store sensitive customer data — contact details, contract histories, communication logs. Conventional CRM systems have vulnerabilities: administrators can alter or delete records without traceability; in data breaches, it is unclear which data was affected and when. Hyperledger Fabric solves this through a permissioned blockchain model: every data change is stored as a new transaction; previous data states remain accessible; access rights are controlled via the Membership Service Provider (MSP) system. GDPR-compliant through a permissioned network: unlike public blockchains, Hyperledger Fabric can restrict data to authorised nodes. The ECOPLAN project is especially relevant for the German Mittelstand, which lacks its own blockchain department: the open-source blockchain installer significantly simplifies setting up a Hyperledger Fabric instance. LIDIA-Hessen (funded by the Hessian Ministry for Digital Strategy and Development) supported the project as a pilot application.

## Benefits

- Small and medium-sized enterprises gain access to enterprise-level blockchain technology without high investment costs.
- Customers benefit from enhanced data protection and tamper-proof storage of their personal information in CRM systems.
- The open-source tool reduces implementation costs by up to 60 percent compared to commercial blockchain solutions.
- Automated installation shortens the rollout time from weeks to a few days.
- Companies achieve GDPR compliance and tamper-proof data storage without their own blockchain expertise.
- IT staff can implement modern security technologies without extensive blockchain training.

## Challenges

- Companies may need to fundamentally revise existing CRM systems to enable blockchain integration.
- The limited scalability of Hyperledger Fabric without sharding mechanisms can become an issue with large data volumes.
- Acceptance of blockchain technology among small and medium-sized enterprises is still low and requires intensive awareness-raising.
- IT employees need basic knowledge of Docker and container technologies to use the tool successfully.

## Technology foundation

The system uses Hyperledger Fabric as a private blockchain solution, installed via Docker containers. Hyperledger Fabric is particularly suitable for companies as it can be operated as a closed network and ensures full protection of sensitive customer data.
