One question on Multi-sig, Can we add also one key called master signature that alone can unlock transaction?

Question

One question on Multi-sig, We know it works if 2 signature are given Can we add also a 3rd one called master signature that alone can unlock transaction? This key should be known only by me ?

Answer 1

You could do this with the following workaround. Have the master key holder own two addresses rather than one address, then use a 2-of-4 multisignature. The master key holder has two keys, and the other key holders have one each, so only the master key holder can unlock the transaction on their own.
