1  Bitcoin / Pools / Mining info from pool on: September 16, 2017, 07:55:42 AM
While getting my head around to understand the mining process and checking in python..... i am puzzled with which info from/to pool are in Little Endian.
Specifically For the merkle root .......do i need to reverse the bytes before/after
For example ............. response to mining.authorize gives me ..... job_id,prevhash,coinb1,coinb2,merkle_branch,version,nbits,ntime,clean_jobs =
Code:
{'id': None,
 'method': 'mining.notify',
 'params': ['59bc8dfc0000029f',
            '0eba48f47bc0ab4bb35b230849868bf1d79aeb19006eed460000000000000000',

            '1801310b',
            '59bcd504',
            True]}

Based on the pool response....I can build the coinbase just by
Code:
coinbase = coinb1 + extranonce1 + extranonce2 + coinb2
coinbase_hash_bin = hashlib.sha256(hashlib.sha256(binascii.unhexlify(coinbase)).digest()).digest()
coinbase:01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff35039a6807000404d5bc5904fc873d140c2be5bc5900000000df9971c00a636b706f6f6c112f736f6c6f2e636b706f6f6c2e6f72672fffffffff03c4626c4e000000001976a914fc6123f4bfd3a840b4387ab90e9801e98fb17cf888acb1caca00000000001976a914f4cbe6c6bb3a8535c963169c22963d3a20e7686988ac0000000000000000266a24aa21a9edab3b87f3963e55a23f3cea5e4435bf6637328fd5e329bb8fdac7d31c3a01d26200000000
coinbase hash: '49f99aaf253e4535147c75fc9e8402c0528437dd09b4181939b28f47aee91c59'
Therefore my merkle_root will be
Code:
fb68998fe1dd4cc22fa1225c2592c27df5331d40d9b33ffce99b26c0aead8ef4
Is this correct ? Do i need to reverse it ? later / before ? for putting in block header and hashing.

Finally to submit a share we perhaps simply need...
Code:
payload = '{"params": ["'+address+'", "'+job_id+'", "'+extranonce2 +'", "'+ntime+'", "'+nonce+'"], "id": 1, "method": "mining.submit"}\n'
sock.sendall(payload.encode('utf-8'))

But i maybe wrong??
