I read the following statement:
2 of 3 wallets are the most common multi-signature wallets created. In this case, the wallet requires three signatures, but only two are needed to authorize a transaction.
Is there any statistical evidence that 2 of 3 wallets are indeed the most common one? Like some graph etc. Any kind of statistical evidence would be good. I want to use this fact in a research paper I am writing. I need some reference to cite.
