1  Bitcoin / Development & Technical Discussion / Re: Prime number Bitcoin keypairs - How and why on: March 25, 2021, 07:34:25 PM

It is beautiful. It is satisfactory. It is nerdy.

You may well be living a "beautiful", "satisfactory" and "nerdy" life to the full extent thinking
you're the only proud owner of private keys created in a convoluted way that happen to hash
to prime numbers and I've got no issues with that.

However I'd like to point out that according to pigeon hole principle on average there exist
2^96 = 79 228 162 514 264 337 593 543 950 336 private keys (prime or not) for any single hash.

So after all it's possible your private key - hash set turns out not as much unique as you thought.

2  Bitcoin / Development & Technical Discussion / Re: Modified bitcrack on: March 19, 2021, 11:07:17 AM
Hi guys ,

Can this tool or any modification of this be modified to write all private keys and respective uncompressed private keys and addresses) in range 1 to 56BC75E2D630FFFFF as a csv file . Since it generates 700 to xxxx million keys /s in some of its versions , so it will take many years on a single machine. But still looking for solutions. Writing regular outputs will consume too much time
So better it will save several millions or billions in some sort of memory operation and then write them once ,  till then next batch will find its space in memory to be written again.

Just before you set out on your endeavor it's just wise to do some planning.

Even assuming that time needed to complete your task is of no significance to you, it is worth a while to think about a storage capacity you will need to write results of your work to.
Basically you are asking for a csv file like this:

P.K. hex format   Private Key WIF(uncompressed)                      Bitcoin Address(uncompressed)

. . .
. . .
. . .

This file is bound to have 99,999,999,999,999,999,999 plus 1 (56BC75E2D630FFFFFh=99999999999999999999) lines of roughly 104 characters each. So to put it another way
one hundred quintillion lines times 104 bytes equals to 10,400,000,000,000,000,000,000 bytes. Using a conversion tool you end up with these numbers:

10,400,000,000,000,000,000,000 bytes (B) = 9685754776000.98 gigabytes (GB)
10,400,000,000,000,000,000,000 bytes (B) =    9458744898.44 terabytes (TB)
10,400,000,000,000,000,000,000 bytes (B) =       9237055.56 petabytes (PB)

To make it easier for you to grasp all of what I stated above I'll paraphrase it:
To complete your task you have to be a rather affluent person. According to this wiki page 1 TB of storage costs $50 so you'd have to fork out $472,937,244,922.
But please worry NOT because I've got some good news for you. The wiki page I've just mentioned must be outdated and I found this little device of which you need 525,485,827 of them.
And that will ONLY set you back mere $209,936,843,020.

Good luck and all the best to you.

...Here is server/client (source and compiled version) for bitcrack, you also need put cu or cl version of Bitcrack.exe to client folder

@Etar would you mind sharing the source code ?

Edit: Please disregard, I got it .

I would like to draw attention of venerable participants of this discussion to the very date of the publication and then OP mark the topic [SOLVED].

No, he isn't.

6  Bitcoin / Bitcoin Technical Support / Re: Get private_key.pem from WIF format on: March 07, 2020, 12:30:51 PM
Actually as OP asked for a pem format (following from example above):

$ openssl ec -inform d < btc_priv.key
read EC key
writing EC key

7  Bitcoin / Bitcoin Technical Support / Re: Get private_key.pem from WIF format on: March 07, 2020, 12:06:50 PM
To feed data to openssl it needs to be formatted rightly.
Following your example:


Concatenate and convert to a binary:

echo $PRE_STRING $YOUR_PRIVKEY $secp256k1_ID | xxd -r -p > btc_priv.key

And there you go:

openssl ec -noout -text -inform DER -in btc_priv.key
read EC key
Private-Key: (256 bit)
ASN1 OID: secp256k1

Where can I find a link for the stats of secured nodes?

10  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][Blocknet] truly decentralized exchange | token ecosystem infrastructure on: December 12, 2017, 09:53:44 PM
if not already posted, here is an impressive list of coins on blocknet exchange, many tested and working...

Any ETA of SAFEX being introduced as one of Blocknet trading currency pair ?
Considering this...

it may be well worth the effort to bring it in ASAP.

I had no problem until the certificate part. Anyone have an idea how to fix this?

Did you try to ping your domain?

Yes it pings fine, I think this is the problem:

I think the .me domain isn't supported by dnssec.

It's working for me. See for example
You have to set Nameservers to Namecheap BasicDNS...

...and then just add an A Record.

alright I say it again, was just analyzing the 40 masternode coins out there:

1. Dash - 4500 nodes, marketcap 5 billion
2. PIVX - 2000 nodes, marketcap 180 mil
3. Crown - 2600 nodes (960 Tron masternodes, 1650 systemnodes), marketcap 27 mil

other masternode coins are left behind

Also, none of the coins out there have a dual node layer

No disrespect but you somehow managed to miss Blocknet which is actually number three and as well established coin, and Pura which
is number four but I've not heard of before.

Edit: Even if you combine CRW and CRW-SN you still will be number five with total market cap of $56.6 mil

How long will systemnode take to get first reward? mine 11 hours, no rewards

The one I've got has been running for 34 hours and still no reward.

No it doesn't work. And this answer mens nothing to me. Would you humor me and run the calculator(if it work) and simulate that you have 1 node, you pay 5$ VPS , and price od zen is 21$, how much zen would you get per month?

Yes it does.
As per your data entry AND assuming there is going to be 2000  nodes online:

or 5000 nodes online:

Hope you're now fully satisfied with me humoring you and running the calculator for you  Roll Eyes

15  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][ZEN] ZenCash: Private, Secure, Resilient CryptoCurrency with zk-SNARKs on: November 04, 2017, 08:11:23 AM
So i now that secure nodes program is still in testing, but how many zencash tokens would one get as a reward of having set up one secure node?

There was a calculator on this site, but i doesn't work anymore.

And even when it did work it showed insane numbers, if i put 1 secure nod, price od zen = 20$ and price of VPS =5$, it would say that i wil earn 741 zencash tokens or some other ridiculous number.

So the question is if i have one secure node when they start to function how much zencash would i get per month?

The calculator still works fine.
The number of nodes you're supposed to input is an estimation of all nodes that will be online.

" Dear Jamie Dimon: quick quiz: which words/phrases are associated with
you and your employer, J.P. Morgan? Looting, pillage, rapacious, exploitive,
only saved from collapse by massive intervention by the Federal Reserve, the
source of rising wealth inequality, crony capitalism, privatized profits-socialized
losses, low interest rates = gift from savers to banks, bloviating overpaid C.E.O.,
propaganda favoring the financial elite, tool of the top .01%, destroyer of
democracy, financial fraud goes unpunished, free money for financiers, debt-serfdom,
 produces nothing of value to society or the bottom 99.5%.

Jamie, if you answered 'all of them', you're correct. The only reason you have
a soapbox from which you can bloviate is the central bank (Federal Reserve) saved
you and your neofeudal looting machine (bank) from well-deserved oblivion in 2008-09,
and the unprecedented, co-ordinated campaign by global central banks to buy trillions
of dollars of bonds and stocks. "

I couldn't have worded it better.

Team should consider to employ one member who will be here for public relations this way investors can be in direct touch with the team here not only on slack. This member should be here on daily basis to answer all questions and to keep comunity tight. This way investor will be more protected from the FUD.
Also this way bitcointalk comunity can be more included in project, and project will get more transparency and legitimity.

Yes we need to do that - working on it now. Hiring/contracting a person to keep Bitcointalk and all social media updated with information. There are a lot of people who have not heard of ZEN that we want to reach.

Good point. Recently another crypto currency surveyed their user base. The results clearly showed that main exposure channels is via

While I understand that  @Zencash, @blockops and other devs are busy with other things, however it's also important to have a in the loop with this project person who could tend to this thread on a daily basis.
