A digital asset custody system dynamically provisions clusters of multi-party computation (MPC) nodes to securely create different private key shares for signing digital asset transactions and generate blockchain addresses for digital asset owners (AOs). Each cluster of MPC nodes is configured for an AO and to operate in a plurality of computing environments. Each of the computing environments is associated with a respective different signing party, and each computing environment includes a respective one of plural MPC node initializers and a respective one of plural MPC node operators. An MPC controller and MPC node initializers perform operations to generate first configuration information for each MPC node in a first MPC cluster of MPC nodes. Each MPC node operator, based on the first configuration information, deploys one of the MPC nodes in the first MPC cluster in the computing environment corresponding to where the MPC node operator operates, such that the one MPC node in the first MPC cluster is deployed into a different one of the plurality of computing environments as compared to the computing environments into which the other MPC nodes in the first MPC cluster are deployed. Analogous operations are performed to generate second configuration information to deploy a second MPC cluster, third configuration information to deploy a third MPC cluster, etc. as desired.

Systems and methods to dynamically provision multi-party computation (MPC) nodes

A method of managing user personal information across a set of service provider sites is implemented, preferably as a web browser plug-in function. As a user navigates to a service provider web site and performs an interaction involving user identity attribute data, the interaction is recorded for later replay. Typically, the interaction is a graphical user interface (GUI) interaction. At a later time, previously-recorded interactions at service provider sites are replayed automatically, i.e., without requiring the user to navigate back to the individual sites and perform the interactions, and (during the replay operation) the user's previously-entered identity attribute data is located and retrieved. A display of the identity attribute data collected from the service provider sites then can be examined, e.g., for any inconsistency among the data. If the user then updates identity attribute data for a given service provider site, the identity attribute data for the site is automatically updated, once again without requiring the user to navigate to the site and re-enter the update directly. The method enables the user to ensure that his or her personal data stored at the service provider sites is up-to-date and synchronized.
