How It Works

The OA Wallet App is built on the OpenAttestation open-source framework, which leverages blockchain and cryptographic technology. This framework provides standards and tools for creating and verifying tamper-proof, secure, and interoperable documents.

Using OA, organisations can issue digital documents that are verifiable without relying on a central authority. The framework supports various use cases, including academic certificates, professional licenses, and legal documents. It is highly customisable, allowing organisations to define their own document templates, data schemas, and validation rules.

Supported by an active community and licensed under Apache 2.0, the framework is open for anyone to use, modify, and contribute to.

The OA Wallet App, also open source, is available for both Android and iOS. It acts as a consumer of OA documents, demonstrating how such documents can be viewed and verified within a mobile app environment.
