1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Need help for NIST5 - NOMP on: April 18, 2021, 12:51:41 PM
Yeah, I tried PM to that guy as well reading his post, but he has DM off for Newbiew :-) shy shy !

Roger that, correct no one mined through pool yet. Btw, it's forked from Electra
3  Alternate cryptocurrencies / Mining (Altcoins) / Re: Need help for NIST5 - NOMP on: April 18, 2021, 12:42:06 PM
That's because the algo isn't NIST5.

It's a fork of it, without any name. The original person who made the coin you forked from, made it all wrong.

Maybe and may not be, it has more than 5000+ blocks already. Mining works file through wallets, it's just the pool that's causing the problem.

Coin's Source code: https://github.com/antimonycoin/antimonysource
System: Ubuntu 16.04 Server
Node version: 8.3.0
Mining Algo: NIST5

I am using NOMP + MPOS. Everything works fine, shares are accepted, but at submit block I get following error:

Code:
0|nomp-server  | 2021-04-18 11:54:54 [Pool]	[antimony] (Thread 1) Share accepted at diff 37.00292371/40.45611629 by miningexpert9120.mining [::ffff:188.166.161.62]

On Googling I found that it has something to do with the Block reward. The coin's block reward is 15, while NOMP block reward has so many zero.

Btw, error on coin daemon is as follows:

Code:
2021-04-18 11:56:09 ERROR: CheckProofOfWork() : hash doesn't match nBits
2021-04-18 11:56:09 ERROR: CheckBlockHeader() : proof of work failed
2021-04-18 11:56:09 ERROR: CheckBlock() : CheckBlockHeader failed

On checking the source code, I see that the error is certainly due to additional zeros in block reward:

Code:
// Check proof of work matches claimed amount
    if (hash > bnTarget) {
        if (Params().MineBlocksOnDemand())
            return false;
        else
            return error("CheckProofOfWork() : hash doesn't match nBits");
    }

here's my coin config for Nomp:

Code:
{
    "name": "AntiMony",
    "symbol": "ANTM",
    "algorithm": "nist5"
}

Check out:
https://bitcointalk.org/index.php?topic=5202782
and
https://bitcointalk.org/index.php?topic=5204219

The person who did it has not logged in for over a year but it seemed like he got it working.
I guess the main question is why? Yes it can probably be done, but there is newer & better pool software out there.

-Dave

No problem using new software as well. Can you share Github link?
6  Bitcoin / Development & Technical Discussion / NOMP for latest Bitcoin Client on: March 29, 2021, 10:53:50 AM
I have tried different NOMP forks (almost 5 of them), and found that almost all are outdated to latest Bitcoin 0.21 version. Can anyone share link of running NOMP or Python stratum compatible with latest BTC version ? Front-end doesn't matter, I'll be using MPOS for that.

Any help in this regard will be very helpful.

Thanks.

Hey,

We have a fully working crypto currency exchange and we are looking for a European Citizen for partnership. Investment isn't much: He/she needs to incorporate company, get required licenses, and day-to-day operations. As it is a working-partner role, low investment will fetch you decent holding in the company.

If this sounds of interest to anyone, don't hesitate to DM and I can brief you about our technical capabilities, application scaling capacity, and other financial things.

Thanks.

Yes, your point sounds much more feasible.

Sorry to ask for more, but can you link me to some document that describes the implementation in bit more details. I understood the overall concept, but just want to understand it better.

To be precise, Let's say we have 1000 wallets and every wallet has two wallet addresses. That brings that total to 2000 wallet addresses that may receive BTC.

If I am understanding this correctly, I need to store all these 2000 address in DB #1 and all txID in DB #2. But what I still don't understand is that I will still have to make call to bitcoin-cli for all the txID with gettransaction <txID> to find the wallet address and then compare it with the DB #1.

Correct me if I am wrong. 

Thanks.

Hey I'm interested in this, This maybe a good opportunity for some one in my side of the world to partner you guys and run this thing from an offshore country, as I am from the states but living between europe and the top of africa. I think this would represent a major opportunity for a crypto group I am trying to get an offshore concept brewing with. I will send you a PM. And lets keep in touch.
Sure. Awaiting your PM. I tried sending you one, but its disabled for "newbie"  Grin Grin Grin

Hi,

We are a team of professionals from India that thought to launch a crypto currency exchange for the masses and then advance to other countries. Keeping the scaling in mind, we invested whatever we had in developing the application, but recently, there are strong insider news that Government of India may make crypto currencies completely illegal and can term a jail for 10 years. There's no way we can go ahead with this project, and also we are broke financially after giving a fruitless legal fight to the government.

In the end, we have decided to sell the application to whoever is planning to develop similar thing from scratch. Some of the technical points are mentioned below. The information is minimum and complete information can be provided after signing the NDA with a serious buyer.

Back-end:
JAVA + Spring Framework

Architecture:
Micro-Services along with Netflix Eureka, Zuul, and Hystrix.

Front-end:
Angular 5

Initial Stress test:
30,000+ successful order execution in 1 minute, on a single server with just one instance of matching service.

Other details:
The application is developed 100% from scratch. For security point of view, it has OAuth2 based authentication for services, and JWT token for users. There are many other things that can be discussed to a serious buyer.

Offer:

1. We are open to license it out or sell exclusively (costly)
2. We are also open to partnership if any foreign individual can manage the operational part, while we manage the technical parts. (Not possible in India, and we don't have funds to form and operate a foreign company)
3. We will provide full support for 4 months in case you wish to license or buy exclusively. The support includes deployment, run-time bugs resolutions, adding or removing minor features, customizing front-end design as per your need, modifying the KYC and registration module as per local laws, etc.


Thanks.

Just out of curiosity, then how does wallets like blockchain.com manage millions of wallet? They may be receiving walletnotify callback every second.

I got your point and we also thought of the same, to run loop for every wallet on our node to check for gettransaction.
16  Bitcoin / Development & Technical Discussion / WalletNotify with Multiple Wallet on Same Node on: June 10, 2019, 02:20:25 PM
Hi,

I am part of a fintech project and we have thousands of users. Instead of getnewaddress, we are using createwallet for all users. Everything is working pretty perfectly, except one critical part.

We are stuck with walletnotify. In our earlier mechanism, we were using one wallet with multiple addresses and thus, walletnotify was helpful. But now the problem is that walletnofity sends the txID, and when we pass the txID in separate gettransaction call, in response we get "specify -rpcwallet=<>"

Now as we ourself don't know which user has made the deposit, how do we keep track of it.

I have check github and there are a few commits on expanding the walletnotify functionality with %s and %w for wallet name. However, that still seems to be in work in progress as the latest pull didn't bring that functionality.

Can someone help how to maintain wallet per user bases and also use walletnotify ?

Thanks a lot Sir !
18  Bitcoin / Development & Technical Discussion / Re: Need Help with setting up Bitcoin Explorer on: July 07, 2018, 06:48:11 AM
Thanks, got your point.

What you can do is request for specific blocks (and transactions if you have enabled the transaction index)

Can you please explain in brief how to enable transaction index ?

So you can get the blocks around the timepan that you want and get the transactions from there to analyze.


If you can guide a little how to get specific blocks from time span

Hello,

I have Bitcoind and Bitcoin-cli setup on my Ubuntu and it is working perfectly fine.

However, I am researching on some serious bitcoin trends during a specific period. Let's say I want to see transaction volume between specific period, day wise. Is there anyway, I can do it ?

Any help will be appreciated.

Thanks.
