Telariust, there is nothing in Source Code, only README.md

UPD: Resolved!

Not know in details but problem with my local (ISP) DNS server. When I start bitcoind with local DNS - it fails to shutdown all time.
When I change DNS to 8.8.8.8 - and start bitcoind - shutdown works ideally!

Maybe my ISP blocks something etc. I just don't have time now to explore this question. Maybe later. For now I just changed to use 8.8.8.8 in my local net and problem gone!

Hi everyone!

I have problem with shutting down bitcoin core on linux platform for years with different bitcoin core versions
bitcoind and bitcoin-qt hungs after shutdown it. In bitcon.conf only one line - server=1

Note that is with empty database (like 1st bitcoind run!)

Here is debug.log with debug=0:

The same configuration with bitcoin testnet shutdowns fine.

Maybe someone can help me with finding where problem is ? I'm very tired with it. Thanks in advance.

UPD: Resolved. It needs to use  -v 239 for testnet in bx ec-to-wif command

Hello all!

I'm trying understand HD wallets in bitcoin core implementation and got stuck. Here it is:

$ bx seed | bx mnemonic-new -l en
reward awake later spot grass list peanut clog hurry guess question father leg dress only reunion horn napkin

$ echo "reward awake later spot grass list peanut clog hurry guess question father leg dress only reunion horn napkin" | bx mnemonic-to-seed | bx hd-new | bx hd-to-ec | bx ec-to-wif
L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG

That WIF key L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG should be ok for sethdseed? Right?

So next:
$ bitcoin-cli createwallet test
{
  "name": "test",
  "warning": ""
}

$ bitcoin-cli -rpcwallet=test sethdseed true L1G3dzjDmkPNkrYLs2L9pTbF9BZ4XThqkXVtDxcrP887uPYRjriG
error code: -5
error message:
Invalid private key

What's wrong?

Thanks in advance.

Im trying to run LBC on my new 7820X:

$ ./LBC -x
Will use 8 CPUs.
Testing mode. Using page 0, turning off looping.
Benchmark info not found - benchmarking... 'kardashev-skylake-avx512' not found/executable.

LBC just downloaded .blf file but not kardashev-skylake-avx512.

LBC version 1.195

Any suggestions what's wrong ?

Rico thanks for answer.

Now I'm slecting MB and CPU only. Not GPUs. But I limited myself only with 1151 socket as 2066 CPUs/MBs overload my budget and also I don't like AMD. The second step will be GPUs but it's a little later.
What you say about https://ark.intel.com/ru/products/126686/Intel-Core-i7-8700-Processor-12M-Cache-up-to-4_60-GHz  with MB https://www.msi.com/Motherboard/B250-KRAIT-GAMING.html ? I'm not very familiar with modern HW so maybe there are better options. Any more advices ? Thanks.

Guys, can you advice what is the best speed/price ratio from Core i5-i7 CPU family for launch LBC soft? Im going to participate and luckly it's time to upgrade my HW. Thanks.

Это я понимаю, но вопрос не совсем об этом. Чтобы у одного кошелька (файла) было несколько адресов, на которые (и с которых) можно отправлять деньги, и чтобы они попадали в один кошелек.

Подскажите, можно ли одному кошельку сделать больше одного счета (публичного адреса)? Если да, то как? Спасибо.

Можно ли узнать, какие непосредственно последовательности найдены в моих шарах? Сколько цифр в первом простом числе ?

Как понять Best share или Best Chains ? Похоже, что это минимальная длина цепочки, которая засчитывается и оплачивается пулом. Но отсюда вопрос, почему при текущей сложности более 10 засчитываются 7,8,9 цепочки (а блок - это цепочка длиной не менее 10 при текущей сложности) ?  Почему не от 1, 2, 3, ... или же только 10 ?

Чем больше вникаю, тем больше вопросов

Добрый день!

Хочу задать вопрос по внутреннему устройству XPM. Что является признаком нахождения блока ? Нахождение цепочки простых чисел определенной длины, а именно - длины "округляя сложность в большую сторону минус 1"? Если текущая сложность 10.42647350, то как только находится цепочка чисел 10 или более, то блок считается найденным. Верно я понимаю ? Пожалуйста, подтвердите или поясните где я ошибаюсь.

И второй вопрос. jhPrimeminer дает такую информацию о новом блоке. Diff: 10.42648113 / 7.00000000 . Как я понимаю, первое число, это текущая сложность, а что означает 7.00000000 ?

Дальше еще будут вопросы. Спасибо.
