Hey, would it be possible to update this tutorial for compliance with the latest core client?
Please update your tutorial on righto website as well.
Thanks
the functions for WIF and private key are wrong or out-of-date,
they generate a WIF of length 51, but actually we use WIF of length 52.
for example:
5K7T2qR7K5MUMDmkJvCEPbUeALuPyc6LFEnBiwWLuKCEVdBp8qV length 51
L1aW4aubDFB7yfras2S1mN3bqg9nwySY8nkoLmJebSLD5BWv3ENZ length 52
A update for python3 would be nice
File "C:\Python27\xxx.py", line 3, in
import txnUtils
File "C:\Python27\xxx.py", line 9, in
import keyUtils
ImportError: No module named keyUtils
Where can I download these modules or libraries?
bitcoin-code/txnUtils.py has the following function defined:
# Substitutes the scriptPubKey into the transaction, appends SIGN_ALL to make the version
# of the transaction that can be signed
def getSignableTxn(parsed):
first, sig, pub, rest = parsed
inputAddr = utils.base58CheckDecode(keyUtils.pubKeyToAddr(pub))
return first + "1976a914" + inputAddr.encode('hex') + "88ac" + rest + "01000000"
What is this magic number? -> "1976a914"
is the code still valid and maintained ?
i mean does it gives correct output of
keyUtils.privateKeyToWif
keyUtils.keyToAddr
