Every transaction input consists of a number of fields:

  • The txid of the transaction whose output is being spent.
  • The index of the output being spent (also called vout).
  • The scriptSig, or unlocking script.
  • The sequence number.
  • (SegWit inputs only) The scriptWitness.

The first two (txid, vout) are called the outpoint.

  • Thank you, but how get info of input input? May 31, 2018 at 8:30
  • By looking it up. Find the transaction with that txid, and look at its output number vout. May 31, 2018 at 14:50
