Re: How to find multisignature transactions ?

Thanks for your replies

I use bitcoin-etl to download data from the blockchain. So which parameters can be useful to recognize and analyze addresses/transactions? How to recognize segwit addresses (pubkeyhash could be multisig or segwit) ?
I think about "inputs": "script_asm", "required_signatures", "type"; "outputs": "required_signatures", "type". What do you think ?

Code:
