The issue is...... info we get in the job from any pool...... some of them are in little endian and some are not........
I am specifically worried about merkle_root.... whose hash... is needed to build block header...
Anyway thanks
Topic: Mining info from pool (Read 618 times)
its about the process in mining ......... get info from a pool.... select extranonce2...... build coinbase...... hash it.... add with merkle branch... calculate merkle_root....... make block header....hash it .... compare to target difficulty..... if less....... then Enjoy!! ....... You found a share......

You've embarked on a journey of pain and suffering. I feel for you, I've been there.
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 =
Based on the pool response....I can build the coinbase just by
Finally to submit a share we perhaps simply need...
But i maybe wrong??

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

Therefore my merkle_root will be coinbase_hash_bin = hashlib.sha256(hashlib.sha256(binascii.unhexlify(coinbase)).digest()).digest()
coinbase:01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff35039a6807000404d5bc5904fc873d140c2be5bc5900000000df9971c00a636b706f6f6c112f736f6c6f2e636b706f6f6c2e6f72672fffffffff03c4626c4e000000001976a914fc6123f4bfd3a840b4387ab90e9801e98fb17cf888acb1caca00000000001976a914f4cbe6c6bb3a8535c963169c22963d3a20e7686988ac0000000000000000266a24aa21a9edab3b87f3963e55a23f3cea5e4435bf6637328fd5e329bb8fdac7d31c3a01d26200000000

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'))
sock.sendall(payload.encode('utf-8'))
But i maybe wrong??
