How it works
A shared ledger with a private side.
At its base, the Partisia Platform is a decentralized blockchain: an immutable ledger that hosts smart contracts and coordinates the components running on it. Like any blockchain, the ledger and the contracts on it are transparent and tamper-evident.
What sets it apart is what a contract can do alongside that ledger. A Partisia smart contract can add a privacy layer parallel to the immutable ledger: through the contract you allocate MPC nodes that compute on secret-shared inputs. A single contract can keep a shared, auditable record and a private computation side by side — something a normal blockchain can't do, because everything on it is visible to every participant.
The contract is the coordinator. It defines the computation, the MPC nodes read what they need from the blockchain, and the nodes — each paired with a blockchain node — form a cluster that computes on the secret-shared data. Communication stays inside the cluster, so nodes coordinate without exposing data to other blockchain participants or anyone outside.
