Hello.
I'm asked on the different forums but no answer. Maybe here?

There in cgminer(based on cpuminer) exist such code:

static uint8_t diff_to_bits(double diff)
{
   uint64_t diff64;
   uint8_t i;

   diff /= 0.9999847412109375;
   diff *= (double)2147483648.0;
   if (diff > 0x8000000000000000ULL)
      diff = 0x8000000000000000ULL;
   /* Convert it to an integer */
   diff64 = diff;
   for (i = 0; diff64; i++, diff64 >>= 1);

   return i;
}

static double bits_to_diff(uint8_t bits)
{
   double ret = 1.0;

   if (likely(bits > 32))
      ret *= 1ull << (bits - 32);
   else if (unlikely(bits < 32))
      ret /= 1ull << (32 - bits);
   return ret;
}

How to adapt this code for scrypt to calculate diff to bits and vice versa?

Thanks!

Hello there!
For bitcoin:
difficulty = first_block_target / current_target
Is it correct for LTC? If not - how to calculate it?


More
For BTC (first block bits=0x1d00ffff)
target=
0x00000000ffff0000000000000000000000000000000000000000000000000000

for LTC if follow same way (first block bits=0x1e0ffff0)
target=
0x00000ffff0000000000000000000000000000000000000000000000000000000

That's true?

Also there in cgminer presents such code (from BTC asic driver):

static uint8_t diff_to_bits(double diff)
{
   uint64_t diff64;
   uint8_t i;

   diff /= 0.9999847412109375;
   diff *= (double)2147483648.0;
   if (diff > 0x8000000000000000ULL)
      diff = 0x8000000000000000ULL;
   /* Convert it to an integer */
   diff64 = diff;
   for (i = 0; diff64; i++, diff64 >>= 1);

   return i;
}

static double bits_to_diff(uint8_t bits)
{
   double ret = 1.0;

   if (likely(bits > 32))
      ret *= 1ull << (bits - 32);
   else if (unlikely(bits < 32))
      ret /= 1ull << (32 - bits);
   return ret;
}
I think that need to alter this line for LTC:
diff *= (double)2147483648.0; but how?

So how to adapt this code for LTC?

I'm trying to ask on different forums but no answer.
Somebody please help.
Thanks!

Требуется программист который сможет переписать юсб драйвер для асика.

Я уже спрашивал - нет ответа. Помогите кто-нибудь, договоримся.

Но ведь в лайте сложность считается по другому. в цгмайнере ведь:

   d64 = truediffone;
   if (opt_scrypt)
      d64 *= (double)65536;
   d64 /= diff;

Если сделать так, будет работать?

static uint8_t diff_to_bits(double diff)
{
//   uint64_t diff64;
        uint64_t diff64 = 0x0000ffff00000000ULL;  //Для BTC:  0x00000000ffff00000000ULL
   uint8_t i;

   diff /= 0.9999847412109375;
   diff *= (double)2147483648.0;
   if (diff > 0x8000000000000000ULL)
      diff = 0x8000000000000000ULL;
   /* Convert it to an integer */
   diff64 = diff;
   for (i = 0; diff64; i++, diff64 >>= 1);

   return i;
}

Для лайта d64 *= (double)65536;

Никак не пойму, как пересчитать.

Помогите с кодом. Хотел послать Bам мессичж, но не получается.

Как преобразовать этот код  для лайткоинa?

Для биткоина это выглядит так:

static uint8_t diff_to_bits(double diff)
{
   uint64_t diff64;
   uint8_t i;

   diff /= 0.9999847412109375;
   diff *= (double)2147483648.0;
   if (diff > 0x8000000000000000ULL)
      diff = 0x8000000000000000ULL;
   /* Convert it to an integer */
   diff64 = diff;
   for (i = 0; diff64; i++, diff64 >>= 1);

   return i;
}

static double bits_to_diff(uint8_t bits)
{
   double ret = 1.0;

   if (likely(bits > 32))
      ret *= 1ull << (bits - 32);
   else if (unlikely(bits < 32))
      ret /= 1ull << (32 - bits);
       applog(LOG_INFO, "ret=\n",ret);

   return ret;
}

Спасибо!

edit.

У меня в клиенте только сейчас подтверждаются транзакции от 14 15 числа. Думаю, что, как только все перейдут на цепочку от дева, всё будет в порядке.
Кстати, несколько раз перегружал клиента и делал repairwallet. Сейчас у меня всё OK.
P.S. Fucki*g recaptcha.

Guys!
I think that you have to say many thanks to @ideaupdater.
First of all he react very fast coz new checkpoints and right blockchain on github commit were updated very fast- in 17 hours!!!
Some coins do that things in weeks
I'm also coder and have my very own coin and I can understand all the problems too.

So thank You @ideaupdater for your work.
Regards.

I was checking cryptopia - no coins in my account
Looks like cryptopia for now in a wrong chain.

Yep, same chain. Last thing check if cryptopia there too

No, I was sending to cryptopia and can say that my transaction appears on explorer so it's right chain
Will check after 30 confirmations if funds arrived there.

Post your wallet here and I will send you 1 coins to check too.
Or PM me with wallet. We need first of all check chain.

We are on the same chain. OK will try to send some to cryptopia

Block number?

@kassex
Can you check chain too? Please past hash of any block. I want to compare.

@forexhercules
Can you please enter from debug console
getblockhash 578571

end past hash here? If it's equal my previous post likely we are at right chain.


@kassex
type from console repairwallet after reboot

I was compiling latest wallet from github with new checkpoints:
https://github.com/masternodecoin/masternodecoin/commit/f4e19a404643c36bf7df5c15768e8f2b4b432e9f

also using latest blockchain:
https://mega.nz/#F!BThmTQQS!sXY7k6-eERbpi_9fUJdpVg

Synchronized and staking too but if try to send some to cryptopia coins didn't arrived. Maybe cryptopia at wrong chain or what?

BTW can someone check chain?

@ideaupdater
Can you please upload right chain?
Definitely can't synchronize
Thanks.

Masternodecoin- очень хорошая монетка. Тоже есть 2 ноды, брал по 0.6 BTC. Тоже давно окупились. Осенью 100% поднимется.
