That is, no pool can only solo mining?

You are strong, you will come up is not it? All the miners will thank you. Grin

hmm, from what I read, it says anyone mining this coin at the moment is getting screwed by dev Grin

(miner or not not a good coin to mine)

pool mining isn't hard, the dev is screwing you all

So, tlas -

What I want to know is: Did you do it on purpose, or were you too busy creating a stream of crapcoins to be careful enough?

elaborate please ... Huh

Let's make it a homework question. Here's the hash code from tlas, stripped down a little. What's the bug?

SHA256((pbegin == pend ? pblank : (unsigned char*)&pbegin[0]), (pend - pbegin) * sizeof(pbegin[0]), (unsigned char*)&hash1);

BitSequence hashval[32];
Hasht1( 256, (const unsigned char*)hash1.ToString().c_str(),256, hashval );
uint256 hash2;
SHA256((unsigned char*)&hashval, sizeof(hashval), (unsigned char*)&hash2);
return hash2;

Hint - here's the function prototype for Hasht1. Following the NIST standard API, all lengths are in bits:

HashReturn Hasht1(int hashbitlen, const BitSequence *data,
DataLength databitlen, BitSequence *hashval);

So this coin is broken? in what way? Please explain in English.

Thanks.

[13:39] archit: @squaggle You really like giving homework, tlas coin page Cheesy

[13:56] shotuser: @squaggle 3rd argument to hash1 shouldn't be integer, prototype says its of type 'DataLength' whatever that is
[14:12] squaggle: @archit I know. It's a terrible occupational hazard.
[14:12] curiouser: @squaggle 3rd argument to hash1 should be 512, not 256
[14:12] squaggle: @shotuser minor nit. there's a really serious stupidity.
[14:12] squaggle: @curiouser You get the prize.

[14:13] squaggle: And, more generally, that hash function is a speed benchmark of sprintf.
[14:13] curiouser: yeah seems pretty silly
[14:13] squaggle: sprintf is called 32 times every iteration of the loop.
[14:14] curiouser: not a very nice way to wake me up, though

[14:14] squaggle: *grin*
[14:16] shotuser: ha i got the right arg at least ;p still clueless without checking the source why it should be 512 instead of 256
[14:16] squaggle: It's called "how to convert a 256 bit hash function to a weak 128 bit hash function with HUGE slowdown" - a nice way to have a private miner that runs 100x faster than anyone else's without a lot of work.

So the inbuilt miner is critically broken.

WTS 10K TLS for 0.2 BTC for all.

Fablio2 is bad trader, We talked business about 0.1 BTC = 10K LTS, and I send he 0.1 BTC, now he just selling my 2500 LTS,

and he returned my 0.075 BTC, Bad faith! Cry

Just tryed to find out more about the twister algo but twister-hash.com redirects me to pron and the dev website is a joke. Can't trust someone who doesnt even bother to give information
