```python
|
|
336
|
+
|
|
337
|
+
scriptSig = binascii.hexlify(self.varstr(sig)).decode('utf-8') + binascii.hexlify(self.varstr(pubKey)).decode('utf-8')
|
|
338
|
+
|
|
339
|
+
```
|
|
340
|

sigの元のtxhashの元のrawTransactionの中を変更したりしました。

```python

scriptSig = binascii.hexlify(self.varstr(sig)).decode('utf-8') + binascii.hexlify(self.varstr(pubKey)).decode('utf-8')
|
|
344
|
-
|
|
345
|
-
```
|
|
346
|
-
|
|
347
|
-
をscriptSig = sig + pubkey + pubkeyにしたり
|
|
348
|
-
|
|
349
|
-
sigの元のtxhashの元のrawTransactionの中を変更したりしました。
