(ANN) Netcoin has gone POS! With PIR & OWI

[lifeforcepools]

@lifeforcepools

You are dead right lifeforcepools, we have been working on it and we do actually have a better version we are testing right now... Obviously we don't want to rush something out there only for it not to work as intended again as these changes require a hard fork. But I can tell you that tests are looking much better than they do currently. I wouldn't say perfect though just yet.

Also you can tell a POS from a POW by looking at the version, I'm really sorry but I didn't see you ask this before... If I had seen I would have told you. POW is version 2 and POS is version 3... You can see this on the block explorer.

But really great news about your new site and wanting to include Netcoin into it. Thanks you so much for that and just know that we are working our hardest to get it all done the best we can. Obviously many of us have other life commitments but we are working every spare hour we have on Netcoin. As soon as we are done and we have a stable release we'll let all you guys know I promise. It shouldn't be long now. To be honest, I am pretty happy to release it as it is now.

@CrazyLoaf

This has been discussed and it really is a tough call because as you can see from the above post people like to mine, so I wouldn't want to remove the mining feature purely for that reason really. But I am open to see what the community thinks... I think once we get the mining sorted out there really isn't much need to remove it. We're very nearly there too.

I don't see version anywhere or do we need to read more detailed information from the block chain database?

Hey LifeForce,

Sorry, I'm not aware of such a script at the moment.  Within the wallet itself is a link to the Explorer (Go to "services" and then to "useful links" so you can quickly check that way.  We'll dig a bit and see if there is anything out there.  If you come across anything (if you are searching as well) let us know!

[lifeforcepools]

I'm not sure if anyone here is interested in this project but Netcoin is part of it:

I have finished the french translation. Could you give me a mail to send it ?

Thanks

[vsmamm]

NETCOIN need more pormotion, let's do it together

[Mr. Net]

OMG 500 SAT at bittrex!

People you need to get some NET over at Bittrex! People are starving!

[yogibaer]

wow great! GO NET!

[SnappySnap]

So that just happened apparently.  You blink and forget about NET, and then all of a sudden it jumped from 100 to 200+.

Well, GO NET! 

*grumbles...should have paid more attention to the charts.....

On behalf of NETCOIN and the Foundation, we wanted to give you an update on the coin and the most recent developments. We have made some updates, and will require an upgrade prior to Block 438500.

Here’s a quick breakdown of the upgrades which will fix:

1) Issues with digishield that we found in the code and
2) Improve transaction times.


So here's what you'll need to do:

1) Download the latest client (version) of the wallet (available here: http://netcoinfoundation.org/).  It'll be version 2.2.0
2) If you want, backup your current wallet.dat (There's really no need to, but as we encourage people to backup their wallets once a week and after any major transaction, it's a good habit to get into).
3) Extract, and launch the new wallet.

That's it.

As always, thank you for your support of NET.  

Should you have any questions or concerns, please do reach out to us at the Netcoin Foundation.

All the best,

` The Netcoin Foundation

Great work guys...and looking forward to continued improvements!

[coinerer]

Let's correct some mistakes in the source code because I can't compile Windows wallet.

Source code is from https://github.com/netcoinfoundation/netcoin

1) In the source code it is missing folder
        src/leveldb

2) and in the source code it is missing files
        src/leveldb.cpp and src/leveldb.h

3) in the source code it is missing 2 folders:
        src/obj/
        src/obj/zerocoin

For 1) and 2) I used files from Litecoin 0.8.7.4. Very likely you can use files from the newer versions of Bitcoin.

Adjust configuration files too.

[Netcoin Foundation]

Hey coinerer, are you talking about the windows Qt or netcoind?

But yeah I know these folders need creating for linux netcoind and most likely for the windows netcoind too... It's something I keep meaning to do and infact we did do at one time but I think they got lost along the way somewhere XD

I will get that sorted soon as possible.

Thanks for the heads up

EDIT: Oh, what did you mean by "Adjust configuration files too."?

Thanks again.

EDIT:

Sorry forgot to mention, we don't use leveldb. Which is why they aren't there.

[coinerer]

1) At the beginning of makefiles (for netcoind .exe) add if necessary:

# Copyright (c) 2009-2010 Satoshi Nakamoto
# Distributed under the MIT/X11 software license, see the accompanying
# file license.txt or http://www.opensource.org/licenses/mit-license.php.

CXX ?= g++

USE_UPNP:=0


2) then change every appearance of g++ with $(CXX)


3) Below obj/noui.o add:


    obj/noui.o \
    obj/zerocoin/Accumulator.o \
    obj/zerocoin/AccumulatorProofOfKnowledge.o \
    obj/zerocoin/Coin.o \
    obj/zerocoin/CoinSpend.o \
    obj/zerocoin/Commitment.o \
    obj/zerocoin/ParamGeneration.o \
    obj/zerocoin/Params.o \
    obj/zerocoin/SerialNumberSignatureOfKnowledge.o \
    obj/zerocoin/SpendMetaData.o \
    obj/zerocoin/ZeroTest.o


4) In makefiles (i am interested in makefile.mingw ) below obj/%.o: .... add commands for compiling obj/zerocoin/%.o : ...


obj/%.o: %.cpp $(HEADERS)
   $(CXX) -c $(CFLAGS) -o $@ $<

obj/zerocoin/%.o: zerocoin/%.cpp
   $(CXX) -c $(CFLAGS) -o $@ $<

[coinerer]

Why is new PoW block 400 instead of 320 in Netcoin v2.20 ?

[Netcoin Foundation]

@ coinerer and everyone really... I think there has been a major balls up stemming back from a long time ago... Back from when we had KGW put in... I'm not 100% so I need your thoughts here...

But to answer you coinerer I missed out an else statement and I think with the difficulty it is the same deal, but I am not fully to blame for that one. So here is the code that we have now for chosing which diff retarget to use...

// POW blocks tried various algorithms starting at different block height
unsigned int GetNextProofOfWork(const CBlockIndex* pindexLast, const CBlock* pblock)
{
    const CBlockIndex* pindexLastPOW = GetLastBlockIndex(pindexLast, false);

    // most recent (highest block height DIGISHIELD FIX)
    if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_DIGISHIELD_FIX_START_TESTNET : BLOCK_HEIGHT_DIGISHIELD_FIX_START))
        return GetNextWorkRequiredV2(pindexLastPOW, false);

    // most recent (highest block height)
    if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_POS_AND_DIGISHIELD_START_TESTNET : BLOCK_HEIGHT_POS_AND_DIGISHIELD_START))
        return GetNextTrust_DigiShield(pindexLastPOW, false);

    if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_KGW_START_TESTNET : BLOCK_HEIGHT_KGW_START))
        return GetNextWorkRequired_KGW(pindexLastPOW);

    // first netcoin difficulty algorithm
    return GetNextWorkRequired_V1(pindexLastPOW,pblock);
}

I THINK it should have been like this

// POW blocks tried various algorithms starting at different block height
unsigned int GetNextProofOfWork(const CBlockIndex* pindexLast, const CBlock* pblock)
{
    const CBlockIndex* pindexLastPOW = GetLastBlockIndex(pindexLast, false);

    // most recent (highest block height DIGISHIELD FIX)
    if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_DIGISHIELD_FIX_START_TESTNET : BLOCK_HEIGHT_DIGISHIELD_FIX_START))
        return GetNextWorkRequiredV2(pindexLastPOW, false);

    // most recent (highest block height)
    else if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_POS_AND_DIGISHIELD_START_TESTNET : BLOCK_HEIGHT_POS_AND_DIGISHIELD_START))
        return GetNextTrust_DigiShield(pindexLastPOW, false);

    else if (pindexLastPOW->nHeight+1 >= (fTestNet ? BLOCK_HEIGHT_KGW_START_TESTNET : BLOCK_HEIGHT_KGW_START))
        return GetNextWorkRequired_KGW(pindexLastPOW);

    else// first netcoin difficulty algorithm
    return GetNextWorkRequired_V1(pindexLastPOW,pblock);
}

Am I right? If so... I am not sure how we can fork it like that... Because as you can see non of the else statements are there. Some help would be greatly appreciated.

Which coin is the most similar to Netcoin at this moment?
