How to the decomposition of multi signature

Hi,
I came from Japan. I’m sorry to post in poor English.

Now,
I have examined Is it possible to decompose the multsig.
In particular, I will use more than 3 encryption information, and generate multsig.

e.g.

  1. public key generated by my account ( = address , wallet)
  2. hash generated in the previous block
  3. public key generated by the SIM authentication capabilities in smartphone

But,
I could not understand multsig generating method.
( I read NEM NIS API Documentation many times, and try it. )

Question,
In the present specification, is it right the below ?

  1. public key generated by my account ( = address , wallet)
  2. hash generated in the previous block ( = hashfunc)

Kind regards,

It’s not clear why you want the previous block hash for multisig.

What the hell is a maruchishigu? :slight_smile:

Hi rigel,
not “maruchishigu” but "multsig (short for: multi signature) "
I am ashamed, and changed title.

Hi makoto,
I know very little about multsig.
The first step, I want to know multsig generating mechanism.

I understood that it was basic because of reading Mastering Bitcoin.
Maybe…

Here is the tutorial on multisig.

NEM’s multisig is completely different than Bitcoins.

Bitcoin’s multisig was a hack that was put in after the fact. In Bitcoin you combine lots of keys to make a transaction.

NEM’s multisig was planned out carefully and is a contract on the chain. In NEM there are parent accounts and a child account. When you make a multisig account in NEM, you are making a parent account have control and power over a child account. You may also edit this contract at any time adding or removing signers. You can even remove the contract and turn the child account into a regular account again.

Hi jabo38,

I cound understand very well.

Thank you so much !

glad I could help
