PetNet, a decentralized network designed to perform computations on encrypted data without revealing it, is now launched. The network’s nodes are operated by corporate participants.
Nillion launched PetNet, a decentralized computational network where data is processed without decryption and without operators having access to its contents. PetNet’s infrastructure is focused on executing computational tasks in a distributed environment without the need to decrypt information. PetNet nodes are already supported by major corporate operators including Deutsche Telekom, Alibaba Group, Saudi Telecom Company, and Vodafone.
According to the announcement, over 35 billion records containing personal, financial, medical, or other sensitive information were compromised in 2024. The average damage from a single security incident for companies amounted to $4.88 million.
In PetNet’s architecture, data is split into encrypted fragments before computation and distributed across nilDB nodes. Computations occur within the nilCC trusted execution environment (TEE). At all stages, data exposure in plaintext form is completely eliminated.
Each node sees only a portion of the data, removing the need for a central trusted party. Security is ensured by the network’s structure. Operators provide computational resources, maintain node uptime, and ensure compliance with the distributed network’s requirements.
Use cases include:
- analysis of network metrics without access to user data in the telecom sector;
- anomaly detection and risk assessment on encrypted data in the financial sector;
- joint computations on medical data sets without sharing personal information in healthcare and more.
PetNet supports configurable security levels, choice between corporate and independent operators, and the use of private hosting.
PetNet can be classified as a DePIN project, which in 2025 remains one of the most in-demand sectors in the Web3 industry. For example, by September 2024, there were about 1,500 active projects in this area with a total market capitalization exceeding $50 billion.
