C_Chain is a blockchain
not a distributed ledger

It’s faster, less complex
and extremely secure.

Solution

The principle of C_Chain is innovative. And so are the applications you can build with it.

We have completely rethought the approach of distributed ledgers such as Bitcoin or Ethereum, and developed C_Chain. With C_Chain as a foundation it is possible to develop software that offers many benefits of distributed ledgers and, at the same time, offers so much more.

Our new Proof of Correctness uses multiple signature layers. Each block is signed by the user and C_Chain. This ensures chains are immutable and correct, thereby providing completeness and verifiability for the whole system.

Why C_Chain exceeds distributed ledgers when it comes to securing and digitizing your business processes.

  1. With C_Chain the number of concurrent chains is unlimited, and the authority is more central. This makes C_Chain extremely efficient and fast, and additionally increases scalability significantly compared to distributed ledgers.
  2. Due to its energy efficiency, lean architecture and less computationally intensive nature C_Chain makes implementation, operation and maintenance inexpensive for applications that use it.
  3. C_Chain is forgery-proof and you are in control of how your data is managed. This allows C_Chain applications to be built in a GDPR-compliant manner, making it the ideal foundation for digitizing delicate business processes.
  4. C_Chain can be used in a versatile way for a large variety of use-cases. Because of its groundbreaking performance and excellent scalability C_Chain can be employed in new areas distributed ledgers are unsuited for, like IoT.

The comparison reveals the benefits of C_Chain

 

Bitcoin Ethereum C_Chain
Type Cryptocurrency Smart contract platform Blockchain-as-a-Service platform
Applications Smart contracts, currency DApps, currency Arbitrary use-cases
Number of chains 1 1 Unlimited
Block time ~ 10 min ~ 13 s ~ 15 ms per chain
Storage location Decentralized Decentralized Centralized and replicated
Verification Proof of Work Proof of Work Proof of Correctness

 

The comparison shows: C_Chain is faster while being applicable to the same, or a larger number of areas. The chain verification is based on cryptographic signatures instead of computationally intensive hashes, which makes C_Chain much more energy efficient than distributed ledgers. In addition, C_Chain can be deployed on small single-board computers as well as Kubernetes clusters in the cloud.

Applications

Wherever trust is the currency, security is a valuable asset: C_Chain – the smart blockchain made in Germany.

C_Chain is applied whenever delicate business processes need to be modelled in a fast, easy and particularly secure fashion. It doesn’t matter if we’re talking about banks, insurances, governments administrations or companies in the sectors of industry and health. They all have one thing in common, the demand for the highest security possible for their digital processes.

We’re currently working on applications for the following areas:

Governance Contracts, approval processes and sensitive documents are being digitized with the German base technology C_Chain. In this way, administrative matters are accelerated, secured and facilitated.

Healthcare With C_Chain, the patients' medical information is cryptographically secured and managed in accordance with GDPR regulations. This offers endless opportunities to digitize and optimize the healthcare sector.

Automotive C_Chain enables tracking encrypted vehicle data transfers to local authorities and institutions. At the same time, C_Chain supports real-time Car2Car communication while it is arbitrarily scalable relative to the number of vehicles.
