Today, the 4T-DLT initiative, which arose from Leap, digitalswitzerland’s innovation programme, publishes a whitepaper. Broken down into the so-called “4 Trusts”, the authors provide fundamental information on the technical and legal framework to establish and operate a secure, interoperable, reliable and trusted digital infrastructure. The whitepaper is both a navigation guide and a source of knowledge for users, advisors and authorities. Under the umbrella of digitalswitzerland, the  approach of a federative and collaborative innovation is followed to create an open repository for the technical and legal information, definitions and standards that will enable a secure, interoperable and reliable Swiss Distributed Ledger Technology (DLT) infrastructure.
