This parser works great, however the ouput does not have the transaction addresses and BTC quantity explicitly. How do I decode that information?

Appreciate your help.

This is what I see as output:

transactionVersionNumber = 00000001
Inputs count = 02
TX from hash = 4E94BFC9654465092E38279FE94FBB5249FC4D07F2544960BC8A31DD1469DB9E

I have two transactions for a bitcoin address when I want to extract the value of r I notice they are different, what should I do

This more inmportance for us

I am using python 3.6.6 and arch Linux.

Toying around with blockchain parsers I also tried yours ... to little success so far. I added just a print line before the crashing line and set my blockchain data folder.

$ python blockchainParser.py 
Start /home/leo/.bitcoin/blocks/blk00000.dat in 2019-03-21 22:22:55.012799

Hello Denis, indicated the saving of the blockchain to disk D, indicated this path in the software -
dirA = 'D:\BTC\blocks' # Directory where blk*.dat files are stored
#dirA = sys.argv[1]
dirB = 'D:\Result' # Directory where to save parsing results
#dirA = sys.argv[2]

here is the error code -
D: \Result\blockchain-parser-master> py blockchain-parser.py
Traceback (most recent call last):
File "D:\Result\blockchain-parser-master\blockchain-parser.py", line 61, in
fList = os.listdir (dirA)
OSError: [WinError 123] Syntax error in file name, folder name or volume label: 'D: \ BTC \ x08locks'

tried to write another way
dirA = 'D:\BTC\blocks' # Directory where blk * .dat files are stored
#dirA = sys.argv [1]
dirB = 'D:\Result' # Directory where to save parsing results
#dirA = sys.argv [2]

then the mistake is
D:\Result\blockchain-parser-master> py blockchain-parser.py
File "D:\Result\ blockchain-parser-master \ blockchain-parser.py", line 56
dirA = 'D:\BTC\blocks' # Directory where blk * .dat files are stored
^
SyntaxError: EOL while scanning string literal

I tried to run from the root of the C drive and put the blk * file next to it and indicate the path, the error repeats

Tell me what I'm doing wrong, thanks in advance

Hello! Is this meant to be run under Python 2 or 3? Under Python 2, I get:

Start /var/bitcoin/data/blocks/blk00000.dat in 2020-02-26 11:04:09.093834
Traceback (most recent call last):
  File "./blockchain-parser.py", line 79, in <module>
    tmpHex = read_bytes(f,4)
  File "./blockchain-parser.py", line 38, in read_bytes
    data = data.hex().upper()
AttributeError: 'str' object has no attribute 'hex'

Under Python 3 I get:

Start /var/bitcoin/data/blocks/blk00000.dat in 2020-02-26 11:05:58.985973
Traceback (most recent call last):

I'm using data files from bitcoin-core 0.19. Seems similar to issue #3

how can i get all addresses on bitcoin blockchain i mean every address that comited a transaction on blockchain no matter it has balance or not?
for example get list of all addresses in text file
no balance or transaction or anything else just adresses
thank you

It would be very and useful if you could adjust this parser in order to get just the main chain from the Bitcoin's blockchain.

I get the following error as soon as i start the script:

Start /media/aman/BTC_Blockch/blocks/blk00000.dat in 2019-05-03 17:42:56.161722
Traceback (most recent call last):
File "blockchain-parser.py", line 64, in
b = b.encode('hex').upper()
AttributeError: 'bytes' object has no attribute 'encode'

Ideas?

hi! would like to ask its possible to modify script to received rawtx? ScriptSig Size and ScriptPubKey Size must be calculated separately or its just didnt parse? thank for your work!

Please allow it to output the source address for a transaction in either hex or address code (preferably both). Output the R and S values for each transaction (preferably in both hex or integer). Also, output the destination address in hex and normal address for each transaction.
