The Partisia infrastructure combines multiparty computation and blockchain technologies. Both technologies disrupt the basic concept of “trust” by not relying on “a single point of trust”. On one hand, MPC solves for confidentiality by enabling computation directly on encrypted data without sharing the data with any of the involved computation nodes at any time. On the other hand, blockchain technologies provide efficient immutable consensus and transparency into both encrypted and unencrypted (cleartext) computations. In both cases, none of the involved computation nodes can intended nor unintended change or block the agreed-on computation or computational protocol. Hence the Partisia infrastructure solves the very basic objectives for any digital infrastructure; confidentiality, integrity, and availability, with no single point of trust.

These properties may be hard to grasp as it seems almost counter intuitive. It is nevertheless true, and the methods furthermore belong to a class of cryptography dubbed “provable secure”, which means that all properties are represented in maths and every property can be formally proven to satisfy specific guarantees.

All of Partisia’s products are built on this basic infrastructure and exist both as a private infrastructure operated by a given set of nodes as well as a publicly available infrastructure operated by all applicable node operators. This is similar to how you can deploy a docker container in a modern operating system, on the Partisia infrastructure every component can act as a docker container that can be installed and run - thereby defining the configuration.
