Abstract
Methods, systems, and devices for data management are described. A custodial token platform may communicate with a client to support a multi-party computation (MPC) signature for a message. A central coordinator may receive, from the client, a request to sign a message using respective key shares generated by MPC nodes. The key shares may be generated in accordance with an access structure, where the access structure is configured based on a respective set of parameters for the MPC nodes. The central coordinator may transmit a request to execute a MPC signature using a respective key share. The central coordinator may maintain data associated with execution of the MPC signature function by a subset of the MPC nodes using the respective key shares. Additionally, the central coordinator may transmit, to the client, a result of execution of the MPC signature function by the subset of the MPC nodes.
