I’m seeking a solution to share a parent key among children without storing the parent key. In other words, it’s like using TSS over another TSS or a similar approach.

For instance, one of our peers is ORG1, and they hold a portion of a key in the organization ORG, but this organization has three managers. Therefore, we are exploring a solution that would enable ORG1 to participate in the signing process by involving the three sub-organizations of ORG1 without storing ORG1’s private key.

Note: I’m aware that the key can be split among all of them, but based on our service design, we were unable to do so.
