Systems and methods for executing bifurcated digital signing processes for complex communications across multiple computer networks using separate request addressing

A method for executing bifurcated digital signing processes for complex communications across multiple computer networks using separate request addressing, the method comprising:

• receiving a first Multi-Party Computation (MPC) signature component, wherein the first MPC signature component comprises a first signature address corresponding to a composite MPC signature and a first group address corresponding to a first participant group, and wherein the first MPC signature component is based on a first multi-party validation action between a first participant and a first sub-participant in the first participant group;
• receiving a second MPC signature component, wherein the second MPC signature component comprises a second signature address corresponding to the composite MPC signature and a second group address corresponding to a second participant group, and wherein the second MPC signature component is based on a second multi-party validation action between a second participant and a second sub-participant in the second participant group;
• determining that the first MPC signature component corresponds to the first participant group and that the second MPC signature component corresponds to the second participant group;
• in response to determining that the first MPC signature component corresponds to the first participant group and that the second MPC signature component corresponds to the second participant group, using the first MPC signature component and the second MPC signature component to generate the composite MPC signature;
• and
• completing a bifurcated digital signing process for a first cross-network action based on the composite MPC signature.

One or more non-transitory, computer-readable media, comprising instructions that, when executed by one or more processors, cause operations comprising:

• receiving a first Multi-Party Computation (MPC) signature component, wherein the first MPC signature component comprises a first signature address corresponding to a composite MPC signature and a first group address corresponding to a first participant group, and wherein the first MPC signature component is based on a first multi-party validation action between a first participant and a first sub-participant in the first participant group;
• receiving a second MPC signature component, wherein the second MPC signature component comprises a second signature address corresponding to the composite MPC signature and a second group address corresponding to a second participant group, and wherein the second MPC signature component is based on a second multi-party validation action between a second participant and a second sub-participant in the second participant group;
• determining that the first MPC signature component corresponds to the first participant group and that the second MPC signature component corresponds to the second participant group;
• and
• in response to determining that the first MPC signature component corresponds to the first participant group and that the second MPC signature component corresponds to the second participant group, using the first MPC signature component and the second MPC signature component to complete a bifurcated digital signing process for a first cross-network action.
