Bifurcated Digital Signing for Secure Cross-Network Validation

The patent divides the digital signing process into two distinct phases: local multisig validation phase where participant groups independently validate data, and composite MPC phase where signatures are aggregated across groups. This segmentation reduces overall complexity by allowing parallel processing and independent validation at the local level before central aggregation.

The patent implements a nested structure where local multisig validation layers are contained within participant groups, which themselves are contained within the larger composite MPC framework. Each participant group operates as an independent unit with its own validation layer, creating a nested architecture that scales efficiently while maintaining security.

By segmenting the signing process into local and composite phases, the system can scale independently at each level. Local participant groups can be formed and validated separately, then aggregated into the composite MPC framework, allowing the system to handle multiple computer networks and large numbers of participants without increasing overall complexity.

The patent adds a temporal dimension to the signing process by executing local validation before composite aggregation. This sequential approach in the time dimension allows for scalable architecture where local validations can proceed in parallel across different participant groups, then be aggregated in a second phase, effectively handling scale without sacrificing security.

The patent segments the signing process so that local validation occurs first at the participant group level, where data remains private and controlled locally. Only after this local validation does the process move to composite aggregation, ensuring that sensitive data never needs to be shared in plaintext across networks while still enabling efficient processing through parallel local validations.

The patent performs preliminary local validation actions before the main composite signing process. Each participant group completes its own validation of sensitive data locally first, ensuring privacy is maintained during the most critical data handling phase. This preliminary action allows efficient processing to occur without compromising privacy, as local validations can proceed in parallel while data remains encrypted and private.
