Want to suggest the answer for sharing the personal key / different delicate info with a modified SSS scheme.
The important thing options are:
the key restoration is just not attainable with out corresponding signatures
share[i] belongs to privateKey[i] solely, which suggests it might’t be signed with a unique personal key
I hope this strategy can assist on the appliance degree to share delicate info or it may be used as m-of-n multi-signature (that is discussable). Right here is the repo with an idea description and dealing instance in node.js: https://github.com/ega-forever/esss
