items for each transaction in a block: items for each transaction in a block:
* The outpoint of each input, except for the coinbase transaction * The outpoint of each input, except for the coinbase transaction
* The scriptPubKey of each output * The scriptPubKey of each output
The extended filter contains extra data that is meant to enable applications
with more advanced smart contracts. An extended filter MUST contain exactly the
following items for each transaction in a block ''except the coinbase'':
* Each item within the witness stack of each input (if the input has a witness)
* Each data push in the scriptSig of each input
Note that neither filter type interprets P2SH scripts or witness scripts to
extract data pushes from them. If necessary, future filter types may be designed
