John Calian, blockchain expert and former Head of Deutsche Telekom’s (DT) research and development unit Telekom Innovation Laboratories (T‑Labs), was appointed Co‑CEO of Vienna‑based blockchain interface solutions specialist and T‑Labs partner Riddle & Code alongside incumbent CEO Alexander Koppel.

Riddle & Code provides blockchain‑based software and hardware products for sectors including fintech, machine identity, product provenance, renewable energy, and supply chains. Alongside T‑Labs, the provider was involved in the 2019 launch of the Xride programme, described at the time as a “decentralised open mobility ecosystem” based on blockchain technology (Deutsche Telekomwatch, #86). Other partners in the venture included Simple Mobility and Jolocom, where Calian acted as Advisory Board Member from January 2021 to January 2022.

Calian served as Head of T‑Labs for just over two years before stepping down in June 2020. He then stayed on as Managing Director of DT’s blockchain-as-infrastructure spin‑off trust2core and remained involved in the Advisory Board of DT-owned network optimisation and analytics vendor Benocs, although he has now left both posts. In addition, trust2core has since been folded back into T‑Labs.

Calian said his blockchain experience at DT “allowed me to leap into the world of decentralised technologies. I’ve never looked back”. While he was at DT, Calian significantly upped T‑Labs’ focus on fitting distributed ledger technology together with telecoms infrastructure, building out platforms and solutions in areas such as identity, roaming settlement, and IoT.

DT appointed Alexander Lautz as SVP & Head of T‑Labs in August 2020,
