I made a transaction that may be spent by anybody and now I wanna spend it and convey it again to my handle. The issue in it does not have sufficient bitcoin for transaction payment so I am utilizing one other enter for that. That is my code:
def P2PKH_scriptPubKey(key):
return [OP_DUP, OP_HASH160, Hash160(key), OP_EQUALVERIFY, OP_CHECKSIG]
def P2PKH_scriptSig(txin, txout, txin_scriptPubKey, private_key):
signature = create_OP_CHECKSIG_signature(txin, txout, txin_scriptPubKey, private_key)
public_key = private_key.pub
return [signature, public_key]
def get_txout_scriptPubKeys(amount_to_send1, amount_to_send2):
txout1_scriptPubKey = [OP_TRUE]
txout2_scriptPubKey = [OP_FALSE]
txout1 = create_txout(amount_to_send1, txout1_scriptPubKey)
txout2 = create_txout(amount_to_send2, txout2_scriptPubKey)
return txout1, txout2
def send_from_custom_transaction(amount_to_send, txid_to_spend, utxo_index, txin_scriptPubKey, txin_scriptSig, txout_scriptPubKey):
txout = create_txout(amount_to_send, txout_scriptPubKey)
txin = create_txin(txid_to_spend, utxo_index)
new_tx = create_signed_transaction(txin, txout, txin_scriptPubKey, txin_scriptSig)
return broadcast_transaction(new_tx)
def create_txin(txid, utxo_index):
return CMutableTxIn(COutPoint(lx(txid), utxo_index))
def create_txout(quantity, scriptPubKey):
return CMutableTxOut(quantity*COIN, CScript(scriptPubKey))
def create_OP_CHECKSIG_signature(txin, txout, txin_scriptPubKey, seckey):
tx = CMutableTransaction([txin], txout)
sighash = SignatureHash(CScript(txin_scriptPubKey), tx,
0, SIGHASH_ALL)
sig = seckey.signal(sighash) + bytes([SIGHASH_ALL])
return sig
def create_signed_transaction(txins, txouts, txin_scriptPubKey, txin_scriptSigs):
tx = CMutableTransaction(txins, txouts)
for i, txin in enumerate(txins):
txin.scriptSig = CScript(txin_scriptSigs[i])
VerifyScript(txin.scriptSig, CScript(txin_scriptPubKey[i]), tx, i, (SCRIPT_VERIFY_P2SH,))
return tx
def broadcast_transaction(tx):
raw_transaction = b2x(tx.serialize())
headers = {'content-type': 'utility/x-www-form-urlencoded'}
return requests.put up(
'https://api.blockcypher.com/v1/btc/test3/txs/push',
headers=headers,
information="{"tx": "%s"}" % raw_transaction,
)
pv_key1 = "..."
pv_key2 = "..."
my_private_key1 = bitcoin.pockets.CBitcoinSecret(pv_key1)
my_private_key2 = bitcoin.pockets.CBitcoinSecret(pv_key2)
my_public_key1 = my_private_key1.pub
my_public_key2 = my_private_key2.pub
my_address1 = bitcoin.pockets.P2PKHBitcoinAddress.from_pubkey(my_public_key1)
my_address2 = bitcoin.pockets.P2PKHBitcoinAddress.from_pubkey(my_public_key2)
def send_from_P2PKH_transaction(amount_to_send, txid_to_spend1, utxo_index1, txid_to_spend2, utxo_index2):
txout_scriptPubKey = P2PKH_scriptPubKey(my_public_key2)
txout = create_txout(amount_to_send, txout_scriptPubKey)
txin1 = create_txin(txid_to_spend1, utxo_index1)
txin2 = create_txin(txid_to_spend2, utxo_index2)
txin_scriptPubKey1 = [OP_TRUE]
txin_scriptPubKey2 = P2PKH_scriptPubKey(my_public_key2)
txin1_scriptSig = []
txin2_scriptSig = P2PKH_scriptSig(txin2, [txout], txin_scriptPubKey2, my_private_key2)
new_tx = create_signed_transaction([txin2, txin1], [txout], [txin_scriptPubKey2, txin_scriptPubKey1], [txin2_scriptSig, txin1_scriptSig])
return broadcast_transaction(new_tx)
all_money = 0.00015883 + 0.000001
amount_to_send = 0.00000003
txid_to_spend1 = 'c21f572546f11ab142b3099db329c352937449c1757238c4461b6b13de927c7c'
utxo_index1 = 0
txid_to_spend2 = '38610341422c10bb433046e7bb200e4015af178d4031ab4be192c3a93a3c8363'
utxo_index2 = 0
response = send_from_P2PKH_transaction(amount_to_send, txid_to_spend1, utxo_index1, txid_to_spend2, utxo_index2)
The issue is I get scriptPubKey returned false for the second enter and I do not know why.
