Deutsche Telekom Joins PetNet as Node Operator

Deutsche Telekom MMS became an enterprise participant in Nillion's Privacy-Enhancing Technologies Network (PetNet) on June 17, 2025. The company now operates a node in the network's initial Multi-Party Computation cluster.

PetNet’s Approach to Secure Computation

PetNet processes encrypted data by splitting it across multiple nodes. No single operator can access complete datasets during computation. The network uses Multi-Party Computation (MPC) technology, which allows encrypted inputs to be processed without exposing the underlying information.

Traditional MPC systems used fixed configurations for specific tasks. Instead, PetNet allows developers to choose how many participants handle their data and which operators they work with. This flexibility makes the system suitable for larger enterprise applications.

PetNet differs from public blockchains where nodes validate visible transactions. Instead, the network focuses on secure computation where the data being processed remains encrypted throughout the operation. Participants can perform calculations on sensitive information without any party seeing the raw data.

Deutsche Telekom's participation in PetNet adds privacy-focused computation to its existing blockchain infrastructure services. 

Bringing Deutsche Telekom into PetNet is a defining moment for privacy infrastructure,

said Miguel De Vega, Co-Founder and Chief Scientist at Nillion.

Growing Telekom’s Portfolio

Deutsche Telekom MMS already operates validator and node infrastructure on several blockchain networks. The company runs validators on NEAR Protocol, MultiversX, Aleph Zero, and Injective. It serves as a standby masternode on XDC Network and provides compute and storage as a worker node on SQD Network, formerly known as Subsquid.

Participation in PetNet reflects MMS's continued commitment to building secure, privacy-centric, and scalable digital infrastructure,

said Alexander Ebeling, Co-Founder of Web3 Infrastructure & Solutions at Deutsche Telekom MMS.
