Enterprise Blockchain with the TEOS API

Think of our API as a programmatic entry-point into enterprise blockchain that can bridge any gaps between our TEOS Platform’s standard functionalities and your project’s additional needs. With the TEOS API, you can develop custom solutions using our toolbox of four essential blockchain functions to document, tokenize, govern, and trade any kind of asset. You can also interact with the TEOS Platform on a programmatic level and extend your existing solutions with custom tools and apps that use our infrastructure and technologies, like TokenWARP. Use the API to develop any kind of app, software, or tool that interacts with blockchain, including games, exchanges, markets, notary services, and other useful, creative applications.

Vaccination passport on Blockchain

CoreLedger’s TEOS API is currently being used by Notardec to develop an easy-to-use, forgery-proof Vaccination Passport solution for governments.

Authorized persons (e.g. doctors) use the simple online form to create a timestamped entry on blockchain proving that the patient was vaccinated. Any official photo ID can be used to identify the patient, and no private data needs to be recorded.

The passport is automatically created from this entry. To view the passport, simply scan the QR-code with the provided App. The only information needed from the patient to verify their identity is their photo ID.


Prove your data

Notardec, a company based out of CoreLedger Labs LLC in Switzerland, developed a ready to use MVP from start to finish in just 5 weeks using CoreLedger’s API.

Their first product is NOTRZR, a simple but powerful digital notary service using blockchain technology to prove and store data. It has been designed to serve both private users and business customers.


Get control over your data

An application designed to give you control over your data. Files can be encrypted and uploaded to cloud storage. The permission to access, download and decrypt the files is implemented as an Access token on blockchain. You can track each download with full transparency and use the solution to either monetize your data or simply protect it against unauthorized access, even though you are using the internet as the transmission protocol.
