Digital Ledger Systems AG has developed from scratch a swiss made blockchain for the needs of companies, which is modular and flexible. A clean and simple way to integrate new or existing business functions into the blockchain. Digital Ledger Systems AG (DLS) was founded in 2017 and has created a simple basis for companies to implement the advantages of the Blockchain technology, company and industry specific. An efficient way to better protect all data against manipulation, theft and industrial espionage. Everything that happens in the DLS blockchain is unchangeably historicized. In contrast to conventional technologies, not just a "moment" of a file is recorded, but all actions and process steps are generally recorded, resulting in a non-manipulable data history for each file. With this method, the history of the creation of the data is made transparent and provable. This has relevance in various business processes in which cooperation and legal verifiability are key, such as in supply chains, development and production processes, personal data, electronic identities, registration processes, KYC data, AML data, contracts, etc.. Wherever transparency and trust in data is needed, the DLS Blockchain provides the foundation. With the DLS Blockchain platform offer, companies can quickly and easily develop specific Blockchain applications. It has been developed from scratch, "swiss made" and offers a scalable, highly secure and energy efficient platform. It is standardized, modular, dynamically expandable, no block size limit and independent of "miners". It is energy-efficient and meets industrial and legal requirements. Especially for lawyers and companies with sensitive data in contract and data management, we extend the process with the complete and provable history.
