Hi, I'm looking to acquire some miners to send to a co-lo mining facility in the USA, so ideally I want to buy from US sellers.

I'm interested in anything that's reasonably profitable with very low electricity prices, so the EBang Ebit E9-10 machines are good, the Antminer S9s, Halong DragonMint T1, Bitfly Snowpanther A1, Bitfury B8, Innosilicon T2 Turbo, Antminer S11, Canaan Avalon 8 and 9xx series, although I would prefer to buy several cheaper machines than buy only 1 of the more expensive ones.  I'm looking to buy each month, so I'm making a start here.

If you have any of these and are in the USA and want to sell, please post your offers inc. shipping.  I can also trade an Innosilicon A9 ZMaster if there's any interest in that to top up a BTC or cash price.  Escrow preferred unless you have a way high trust rating.

Thanks,
James
4  Economy / Computer hardware / Innosilicon A9 ZMaster 50 ksol, sell or trade for Bitmain machine -Australia on: May 28, 2019, 11:22:09 AM
Hello,

I'm in Australia and have an Innosilicon A9 ZMaster 50ksol machine I bought in late February this year.  It's in top working condition and does well at the moment even with the release of the faster ksol-sec machines.  Slushpool is good, I prefer Nicehash and payments in BTC.

I'm looking to move to different equipment and would like to sell, COD to Australia or BTC/ETH/BCH/ZEC/maybe others (Escrow) asking AU$1500 or best offer.  I'm open to a straight swap or some kind of trade for a Bitmain Antminer S15 or similar, maybe an Innosilicon T3, MicroBT Whatsminer M10S, Bitmain T17, EBang EBit E11+/++, will consider others (I can add cash or crypto on top with the Innosilicon A9 ZMaster if you're interested).  

It's a 620W machine which makes it viable even with crazy electricity prices.  My elec price is 25c kWh after discounts for pay on time etc, and after other variables (hash rate goes up and down although averages out nicely) it makes ~ $50/week on Nicehash.  You can use factory default mode, this is what I choose, or higher performance modes or economy modes (less power, less hashrate).  Adding new pools is easy and simple.  The Web interface is straight forward.

Thanks,
James.

PM for pics or to discuss.

Does anyone know how to hack in BIP34 from block 1 after genesis?

It seems like this almost never works, and is something of a hack.  It fails out with -reindex and -txindex saying bad-cb-height, which is the block height in the coinbase tx.  So to set the BIP34 height and hash, how is that worked in unless you can specify you want BIP34's block height with a CPU miner?  That must be the only way to do it, then go back and validate everything.

Otherwise, maybe the only way to work around it is to skip the genesis block and start from block 1 with that block hash.  Assuming the block heights are in the coinbase tx.

Anyone figured out how to enable BIP34 from the start, aside from genesis?  Like block 1, or doesn't that make sense at all?  Am I missing something?

Thanks!

There's several thousand dictionary word brainwallets which were funded with 0.0000546 BTC back in 2013, however, looking more closely, this is not the typical dictionary word brainwallet. There are 30234 transactions associated with this address!!!

Found a lot of those old ones running a brain wallet search tool with standard spelling dictionaries on most *nix systems, where the dictionary itself was run through a password transform tool.  For instance /usr/share/dict/american-english or equivalent.

Sort-of 5.  Buying is painful, not enough money to splash.

I like to use crypto, buy stuff with BTC/other I can't with $ from other programmers as well as tip devs of interesting projects, and hodl some when I think there could be a chance of a run up on prices.  I think I hodl for different reasons too.  I collect things, including satoshis.

Although I'm not sure I see the point in cashing out sometimes.  It just means I will wait for a dip and buy again, then hope to sell high, in perpetuity. Boring.

Anyways, here is the full tutorial on "How to Make a Cryptocurrency Using Litecoin v0.15 Source" on Hackster.io.  I hope this guide proves useful to fellow enthusiasts who are looking to create something of their own on this forum:
https://www.hackster.io/pjdecarlo/how-to-make-a-cryptocurrency-using-litecoin-v0-15-source-fb5e82
-snip-
I don't know how you guys were actually able to compile the code using those tutorial you gave but I have tried everything possible based on the content of that article and I never saw the wallet compiled, always getting a lot of errors even though I did everything the way it was stated, I think you guys have to relook into those article and come up with something better that is going to work even if we have to pay for it.

I think we sort of assumed a little too much for some people, especially those who have never used a compiler and that sort of thing.  Getting all dependencies installed and exactly where to run commands, a few other bits and pieces to polish it off and get it up and running.

Are you interested in Litecoin or Bitcoin?  I recommend Bitcoin to begin with, it's a bit easier.  It's also much easier to point a cpuminer at it as well and mine away.  I have a cloned Bitcoin I hack on on a VPS and cross-compile my Windows binary, and add my VPS node.  And I use cpu miner on the VPS to mine.

It's a bit hard to compile and run on Windows compared to Linux.  Either Cygwin or MingW with all dependencies (MingW 64-bit is better, use pacman -Ss to search for packages) and you can try WSL and install the Ubuntu 18.04 LTS app from the Windows app store if on Windows 10.  That just makes it a lot easier.

I'm working on a few guides for making alt-coins, and a little more on the end about hacking on the code and hard forks of coins where your chain goes off elsewhere after a certain block height but the difficulty readjusts down so you can actually keep mining and see what happens.  I'll post back when I have it ready; I'm working with a few others.

That aside, what specifically did you have problems with?  Can you give an example?  That would be useful to try and give some better help.

11  Alternate cryptocurrencies / Altcoin Discussion / Re: *** Complete Guide on How to Create a New Alt Coin – Update 2018 *** on: March 27, 2019, 05:14:14 AM
Good guide!

A couple of updates for Bitcoin release 0.17.1 which I wanted to use.

Also if you want to build a Windows GUI wallet, you will have to git clone and add --branch v.0.17.1 (it accepts a tag) so you get the /depends directory and all the stuff inside needed for cross-compile dependencies.  That way you can cross-compile for Win 64 on Ubuntu and get a slick Bitcoin Core wallet.  If you know how to get gitian up and running, you can make a setup .exe.  If you have Mac libs, you can cross-compile for a Mac wallet, too.

So first swap out the RPC port step and instead change it here in src/chainparamsbase.cpp:

Code:
std::unique_ptr<CBaseChainParams> CreateBaseChainParams(const std::string& chain)
{
    if (chain == CBaseChainParams::MAIN)
        return MakeUnique<CBaseChainParams>("", 10332);   // I set my port to 10332, Bitcoin's is 8332, I left the rest alone
    else if (chain == CBaseChainParams::TESTNET)
        return MakeUnique<CBaseChainParams>("testnet3", 18332);
    else if (chain == CBaseChainParams::REGTEST)
        return MakeUnique<CBaseChainParams>("regtest", 18443);
    else
        throw std::runtime_error(strprintf("%s: Unknown chain %s.", __func__, chain));
}

In chainparams.cpp, set the P2P port under the pchMessageStart lines:

Code:
nDefaultPort = 10333;    // Bitcoin's is 8333, I set mine to a thousand above Litecoin's P2P port (9333)

Not long after that, when you create a genesis block with genesisgen or GenesisH0's Python tool, this line should look familiar:

Code:
genesis = CreateGenesisBlock(1553416095, 2546245826, 0x1d00ffff, 1, 50 * COIN);

That was mine, but now do the same thing for testnet, otherwise the daemon will fail with the assert on the genesis hash for it.  So in chainparams.cpp set your genesis block again.  Look for the Testnet (v3) comment and the process is the same for main-net

For bech32_hrp, I left mine as "bc" but you can change that.  Litecoin's is "ltc".  Note that with miners, I found they failed to mine to older style addresses, so you will probably have to bitcoin-cli getnewaddress, then bitcoin-cli getaddressinfo "addr" and find the bech32 address in there, and set that as your --coinbase-addr parameter with cpuminer, then it works.

with chainTxData in chainparams.cpp, set nTime to the UNIX timestamp of your genesis block and the nTxCount and dTxRate both to 0.

An important step to take if you publish your source on github is to mine say 100 blocks and have them confirmed, and adjust your nPowTargetTimespan as a minimum to try and prevent instamining.  People will find it and instamine it immediately, if it looks like a new alt-coin to them, leaving you with the likely situation that they out-gun you with a higher hashrate, and trying to catch up means you could get blocks, but they will all probably get orphaned.  And then leave your blockchain in a mess and your coin stalling.

I set mine to:

Code:
consensus.nPowTargetTimespan = 3 * 60 * 60; // three hours
consensus.nPowTargetSpacing = 2 * 60; // two minutes

to begin with.  It probably still isn't good enough in comparison to implementing DGW v3 or MIDAS or something of your own invention, in particular you might like to have difficulty readjustments done less than every 3 hours as above.  This works out for me just in a test environment, and I usually get my block every two minutes although sometimes a few will pop through every minute then it will slow down again and not find a few blocks for longer than the target of 2 minutes that I wanted.

You can also premine coins for yourself if you want to with the GetBlockSubsidy function in validation.cpp.

Please note I haven't tested this at all, but for example:

Code:
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;

    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return 0;

    // Premine in first ten blocks, the simple approach
    
    // Start with 5000 coins per block after genesis, but otherwise leave default subsidy unchanged
    CAmount nSubsidy = 50 * COIN;

    // First 10 blocks after genesis, up the subsidy to 5000 coins
    if (nHeight > 0 && nHeight <= 10) {
        nSubsidy = 5000 * COIN;
        // You may wish to leave out the halvings below and just
        return nSubsidy;
        // especially if you just premine in block #1 and leave it at that, but check
        // to make sure it doesn't get all screwed up...
    }

    // otherwise leave nSubsidy in its default state
    
    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years. (Not true for my adjustments, pay attention here)
    nSubsidy >>= halvings;
    return nSubsidy;
}

I left the coin supply and subsidy halving for the moment because it doesn't matter, it's not an alt-coin but a learn-by-doing exercise, trying to retrofit in the bare minimum of difficulty adjustments, experimenting with scripts in transactions (enabling some, trying new ones, going a bit crazy there but the programmable money part is a lot of fun for me), and looking at how more privacy of transactions could be implemented.  I expect I'm a couple of years away from that, but I hope to get there some day, otherwise it's worth trying to clone ZCash or another coin.

I think I've covered the bare basic bits as a follow-on to this guide if you want Bitcoin 0.17.1, you might run into make issues after changing everything from Bitcoin to NewCoin and so on.  So for example if the build process fails in doc/man (a situation I ran into before) saying it has no rule to make newcoind.1.  Stop., then just rename bitcoind.1 to newcoind.1 (and same for 3 other files there) then run make again and it will continue where it left off.

For a Windows QT wallet, cross-compiling on Ubuntu 18.04 LTS:

Code:
sudo apt-get update
sudo apt-get upgrade

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3 libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev libboost-all-dev libboost-program-options-dev
sudo apt-get install libminiupnpc-dev libzmq3-dev libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev unzip

// Get into your src directory, e.g.

cd ~/bitcoin-0.17.1

// For a 64-bit Windows wallet

sudo apt install g++-mingw-w64-x86-64

// Set mode to POSIX when it asks after running
sudo update-alternatives --config x86_64-w64-mingw32-g++

// Get ready and change into depends directory
PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g')
cd depends

// This will take a while
make HOST=x86_64-w64-mingw32

// Up one level to your top level src dir (not in /src, up from there to configure and make)
cd ..

// I use the latest Berkeley DB, so if like me you don't need "compatible" wallets,
// always configure with the latest Berkeley DB and pass in --with-incompatible-bdb

// This will also take a while...

./autogen.sh
CONFIG_SITE=$PWD/depends/x86_64-w64-mingw32/share/config.site ./configure --with-incompatible-bdb --prefix=/
make

If all goes well, the 64-bit Windos GUI wallet e.g. newcoin-qt.exe will be in the folder src/qt when compiled. The other tools newcoin-cli.exe, newcoin-tx.exe and the daemon newcoind.exe will be in the src folder.

So I think that's all for now for a quick and dirty Bitcoin 0.17.1 based on last year's Christmas Day release.

https://www.hackster.io/pjdecarlo/how-to-make-a-cryptocurrency-using-litecoin-v0-15-source-fb5e82

A few problems with that, coming from changing things around at the start.

For instance:

make[2]: Leaving directory '/home/research/litecoin-0.15.1/src'
make[1]: Leaving directory '/home/research/litecoin-0.15.1/src'
Making all in doc/man
make[1]: Entering directory '/home/research/litecoin-0.15.1/doc/man'
make[1]: *** No rule to make target 'learncoind.1', needed by 'all-am'.  Stop.
make[1]: Leaving directory '/home/research/litecoin-0.15.1/doc/man'
Makefile:747: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1


Followed the instructions at hackster.io for a later Litecoin than the Learncoin series on Youtube and Shakezula's guide, but all pointless if you can't get going.  The renaming doesn't catch everything in doc/man, so you have to rename manually etc.

There's actually a massive amount of work to be done in creating a new coin to try out new and interesting things, beginning with trying to prevent an instamine problem, e.g. follow the guide to MIDAS and see if you can hack it into Litecoin's code base, or try Dark Gravity whatever v3.  I would really like to try a slightly different PoW from Bitcoin and enable a few opcodes, add new ones, and try it all out on a testnet.  Just for a start, and change the coin supply and some other parameters.  Then there's mining especially with PoW changes, a pool, block explorer, wallets... if you want to try and go all the way some time.  I don't, but I'd like to hack up Bitcoin or Litecoin and try out a few things I personally find interesting.

Haven't had the time just yet but it's on my to-do list after getting the clone process a bit more automated, trying small things gradually, reading up on BIPs, understanding more of the code, reading good books like Mastering Bitcoin and Jimmy Song's new book on learning Bitcoin by writing code, based on his programmingblockchain.com firehose of info over a weekend for those attending his course.

Well, good luck fellow enthusiasts!

Your about 9 years too late if your trying to mine with a CPU.....

Even the GPU days are dying with Monero and Ethereum getting invaded with asics and the problem is only getting worse.
Note he didn't say he was going to mine with "a CPU"...

He said he was going to mine with 72 to 128 muthafukkin' CPUs!! Grin


There's a slight difference there. I bet he'll be making a penny or two.

You can on rentals with a lot of cores, on occasion.  When the price of Pascal goes up you can get a few in a couple of hours which might cost you about US $10, the idea would be to hold if you think they'll come out of the ~ US 25c per PASC range.  I have made pennies.  Grin  A couple of times a few dollars for beer money, nothing really  worthwhile.

On GPU rigs, I don't think there's anything out there to justify renting big GPU rigs for mining.  GCP have business invoice deals where you can mine all you want with big quota increases but you need the invoice for the year, and have to have spent $2,500 for three months.  That's a bit much to spin up a few 8-GPU instances unless you just get really lucky and recover everything, and profit on top.  The saving grace of GPUs I think are their versatility.  CPUs are out for most, almost everything.  ASICs can quickly become useless and once everyone starts snapping them up, if you're a smaller mining operator then you could be on a losing streak, especially if the coin goes down in a hurry.
14  Alternate cryptocurrencies / Mining (Altcoins) / Re: Good coins to mine with big CPU rig? on: March 04, 2019, 06:53:08 PM
it really is not that big of a deal.... 128 cors really is not a game changer in the least!
with the XEON PHI or many other solutions , that amount of cores is a every day run of the muck machine!
example .  =Dell PowerEdge R820
4 cpu with up to 22 cores each that would give 176 cpu processing threads
up to 1.5 terabyte of DDR4 ram

and that is without adding a xeon phi or other .

as for mining coins ... its awesome to watch it slamm those thread lines in the miner but at the end of the day  you lose money
That's why I asked for clarification on whether it's cores or physical cpu. It could be some wild data lab he has with many multiple physical cpu servers.

Not yet but I'm getting there.  The wild lab could be in a year.  Smiley

If you aren't profitable mining on one you won't be profitable mining on 128.

Yeah, but I use them for other things I need, and mine sometimes for the fun of it.  So they aren't mining rigs as such, but they do nice work and find a lot of shares even with difficult coins like Pascal Coin.
Oh I definitely believe you, no one buys 128 CPU to mine. (Is it 128 cores or physical CPU, I think it's coming off as physical CPU but 128 cores feels much more realistic.) The point was it a coin is ravaged by fpga and Asic the difficulty is high so I there is no point in CPU mining it, regardless of how many you have.

Yeah, I have a few with a lot of cores now I use for various things, but I have a machine with 8x Xeon physical CPUs that's quite good for an entry level high compute.  Later I'd like to get into the AMD EPYC CPUs but I don't think I'll be able to do that for a year or so yet.  Each CPU is around $5k I think, I could go slowly with boards in a rack mount that can handle 2x EPYC 7000-series 32-core CPUs and start collecting them.

There are good ways of designing coins that are CPU minable only by having highly serial PoW algorithms, which are amazingly ASIC and GPU resistant, also having high and fast memory requirements where parallelism isn't feasible.  The problem with that is that it can't be too hard otherwise the average person at home can't mine and get any coins.  If they do, those with big rigs will get pretty much all of them.  That's why I like the idea that sprang out of LuckyCoin, the predecessor to DogeCoin (I think...)

So it essentially becomes a lottery coin.  It can be mined on your mobile phone as well.  The PoW rewards according to what random type of selection you make in advance (e.g. 8 hex chars in sequence of the next block hash).  The first to submit with the earliest timestamp wins the block reward.  For a long in-sequence PoW the block reward could be 100 coins; for any 5 out of 10 maybe 1 coin, and a lot of people could share in that.  It would have to be a big or infinite supply coin though, perhaps.  The hard part is how to prevent knowing what the next block hash (double SHA512 of the block) is going to be.  Mobile phone mining could become popular by having an app that submits your hex chars to the network every 5 minutes or so, timestamped and eventually the network will reject submissions and the earliest timestamp with winning "lotto numbers" of the upcoming block hash takes the coins, which could be a lot of people in the case of high probability finds.  Faking the timestamp could be attempted although full nodes would check them out to ensure they seem reasonable, within some condition like timestamp T must be 2 minutes ago < T < 2 minutes before next expected block hash found.  The actual block hashes could only be submitted very quickly within the expected time interval containing the block header and transactions, so there's that option for other miners with electricity to contribute to the network; those finding the SHA512d(block) would always claim an N coin reward.  They would be excluded from submitting lottery mining tickets, though.  This coin would probably still eat a little too much power but otherwise be a lot eco-friendly than coins that consume enormous amounts of power to keep running.

Armagerd it's almost 6am and I'm rambling already.  Grin

Thanks all  Smiley

I wasn't following the ETH Constantinople thing very well.  Or other coins; I appreciate the links and suggestions.  I follow things as much as I can outside my work and I'm quite a fanatic so I was surprised I only had vague memories of CPU minable coins in one of those links.

Yeah, 72 CPU or 128 CPU rig to begin with, one or the other, I could do 256 CPUs later if it seems worth a try.  I can mine Pascal Coin since it's really only minable on CPUs, but gotta have several AMD server CPUs to justify mining there; it makes money but not quite enough to cover costs unless there's big gains in prices later.  I got into these big rigs since I finished the mining part of my own Pascal Coin miner, and assembling it for testing with the latest testnet.  Should be fun.

I wouldn’t deal with OP yet. I have a package looming around Australia and he didn’t pay for it. I’ll delete it if he responds to my many messages.

Kindly stop bothering me until I get a chance to work with my people.  I know the timing is shit and that's my fault.  I should never have made it a corporate purchase.

But I've already told you customs need an invoice that isn't dodgy and something we can deal with.  There's no sign off until this happens.
19  Economy / Computer hardware / Re: [WTB] Any BTC miner on: February 27, 2019, 11:51:55 AM
I know they are not profitable but I would like to play with one.

Preferably a used AntMiner S9 or Avalon machine.


Where are you located? NA or EU? You need to give some details otherwise shipping estimates cant be made - a key factor into deciding if it's worth selling.

Australia

I've been looking at the smaller V9s for my project, although not sure what else I need for it.  The s9 models even here in Aus are way overpriced for machines that can't make profit here in my view.  Although they are good.  Maybe worth the typical ~$500 price tag if you buy lots and co-locate overseas I suppose.

Anyway regional Australia.
So you ignore me?

Not at all.  I don't have an update right at this moment. The timing is unavoidably off and others change their minds a couple of times on timeframes for their own reasons.

Aside from Pascal Coin which can only be mined efficiently with CPU power, are there any good ones that CPU miners can mine?

Say, a machine with 72 to 128 CPUs.

Would like to try something interesting and actually get some shares and maybe a couple of coins.
