The BIP143 docs state that the value is: "value of the output spent by this input (8-byte little endian)"
If I have a single UTXO of value 10,000 sats and I'm using this as an input for a Segwit tx, then when I'm ready to sign the transaction / create the witness section, I use 10,000 as the value? Or is the value the sum of the outputs that I'm sending?
Another example would be this in the BIP example.
Where does the
0046c32300000000 amount (600,000,000 in Decimal) come from?
This would suggest the "value" is the full available amount of that particular input? Or is it the amount of all the inputs combined?
