Doesn't work with stratum

Doesn't work with stratum. Anything wrong in the code?

[filipe3x]

LOG: ERROR template_registry # [Failure instance: Traceback: <type 'exceptions.ValueError'>: invalid address

[sanasol]

invalid address - wallet address maybe?
for same reason i cant setup block explorer, wallet addresses and txids generating by different way not like all other coins.
Anyway code work - generation block hash is right

I think problem is in this code(Hash4 function) https://bitcointalk.org/index.php?topic=519138.msg5881617#msg5881617

[filipe3x]

Coin address seems to be correct

try change in util.py

cksumB = doublesha(addr[:-4])[:4]
to
import fugue_hash
cksumB = fugue_hash.getPoWHash(addr[:-4])[:4]

[filipe3x]

Same error.

[filipe3x]

And everytime I try to connect my miner I get this error:

i have no idea how fix it, same problem with ABE block explorer....

They changed many coin src lines to fugue hashing(even lines that not need for changing 👎 ), cant get work address validation and hashing txs on ABE, spent few days for it...

[sanasol]

write here if you will find solution

[filipe3x]

I will.

[filipe3x]

The problem is in this function https://github.com/Crypto-Expert/stratum-mining/blob/7a6fd9ac30f92e556dd13b8995d36a0ec7845fb1/lib/util.py#L171

def address_to_pubkeyhash(addr) is returning 'None' everytime it runs when it should return return (ver, addr[1:-4])

[filipe3x]

I found a work around. Now the miner is connecting and it's getting work.
The only problem now is all shares are getting rejected with a Share is above target error.

I think the problem is the diff1 value. Do you know what's the diff1 value for fugue?

[sanasol]

Share is above target
i get same error, just commented this checking in stratum, but not sure work pool or not without this.

[filipe3x]

It's working now. I'm getting accepted shares 👍

Still, I'm afraid of using this on a live pool.

Changed diff1 to 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff00000000

[sanasol]

accepting, but is real to find block or still working wrong at all? :D

[filipe3x]

No clue. The only way to find out is to deploy this on a live pool.

[sanasol]

why not? testnet!
use testnet to check

[filipe3x]

testnet doesn't work with most of these new coins.
See filipe3x@ubuntu:~$ fuguecoind: main.cpp:2816: bool InitBlockIndex(): Assertion hash == hashGenesisBlock' failed.`

[sanasol]

okay :(

[sanasol]

let test it, give me worker and address :)

[filipe3x]

It's a local stratum. I don't have a public address : /

[filipe3x]

Alright, I opened a test pool just for this http://crown.bitember.com/

It's for crowncoin, it's the same algo as fugue so shouldn't be a problem

[filipe3x]

Diff1 value is 0x00000ffff0000000000000000000000000000000000000000000000000000000

I think this one is more correct and it's working flawlessly 👍

PS: wait no, it's not :(
