We advise you on the blockchain-based digitization of your business processes and offer you easy access to the advantages of blockchain technology through our in-house developed blockchain solution secChain.

Our experienced team of consultants and developers supports you with our structured procedure for the establishment of blockchain technologies and is characterized by extensive knowledge and experience in the creation of Smart Contracts.

Key Features

Your advantages with secChain

Security against manipulation

Your data is protected from changes by secChain’s own mechanisms. This means write once and read only – verifiable through Trust Anchoring.

Privacy and GDPR capability

The confidentiality of your data and GDPR-compliant deletion of user data is ensured by the microChain architecture.

Developer- and User-Experience

Simple and intuitive operating as well as documented RESTful interfaces make secChain easy and convenient to use, especially for developers.

Trust Anchoring

With secChain you can profit from the trust of public blockchains through so called Trust Anchoring.

Real-time performance and scalability

The slim design and a distributed approach open up the possibility of scaling the computing power of secChain in seconds and performing in real-time, even at peak load times.

Fine-granular rights management

The fine-granular rights management of secChain makes it possible to depict different roles and assign specific user rights.

The Blockchain Hybrid

secChain

With secChain, we have created a blockchain platform that combines the advantages of a private blockchain with the advantages of a public blockchain.

You benefit in several ways, because the resulting hybrid combines the respective strengths, such as the immutability and privacy of your data, performance and scalability of the transactions, as well as the possibility of GDPR-compliant implementation. At the same time, systemic weaknesses of both solutions are eliminated, which means cost and security advantages for you.

secChain offers you flexibility by design and can be individually adapted to your specific business processes.

Our services

Development

Smart Contracts

Smart Contracts are software code that execute automated, digital contracts, conditional statements and business processes on a blockchain basis. With Smart Contracts, contract terms and procedures can be stored as code, which can be executed and monitored independently. They are reliable, secure and efficient. At the same time they are independent and do not require any third-party instances.

secChain offers full Smart Contract support and thus the possibility to execute your administration and process applications automatically.

Due to the non-public storage of Smart Contracts in the secChain, only registered and authorized users can view the code.
