The ECDSA signature method is used to sign a message with a private key. So rather than sharing the signature, could we give a share of the signature to a number of nodes, and who must come together to share the signature. We will only be able to recover it if enough hosts come together to share their shares. In this case, we will use Shamir Secret Shares (SSS) for which we have n shares, and where we can recover the share using t nodes:
