Taking the sum of the the
Txout array is easy, as first eight bytes is the value of the output, but I do not know how to get the value of an input for a
The format of the
Txin blobs is that which is described on the bitcoin.it wiki --
Previous Transaction hash || 32 bytes Previous Txout-index || 4 bytes Txin-script || 1-9 bytes Txin-script || arbitrary number of bytes sequence_no || 4 bytes
How can I get the value of each input?
