How to create an M of N account/transaction in python?

[svabodny]

I'm an experienced developer, and I know a bit about blockchain, but I'm new to blockchain development.

I'd like to make an M of N multisig wallet app in python. What libraries do I use?

What's important - I want high values of "N" - 6 of 10, or 11 of 20, not just 2 of 3. I heard there's a difference in handling these.

Python bitcoinlib should have what you need: https://github.com/petertodd/python-bitcoinlib

The greatest m-of-n that you can use is 15-of-15.

Thank you!

I guess Segwit will allow signatures more advanced than 15 of 15, right?

No. The scripts are still the same so it is limited to 15 of 15.

Oh, that's sad. I though SegWit will allow extra opcodes in the script (with time)...

Segwit allows script versioning for future changes. Those changes could include additional op codes.
