[ANN] official NovaCoin thread - the original PoS+scrypt coin.

[pocesar]

testnet never seem to sync, connected only to 1 node, what can I do? forever stuck on 16 block remaining

[Balthazar]

Hm, how many blocks downloaded?

TestNet is quite small for the moment.

after 30 minutes, it cleared up, and downloaded the remaining blocks, just needed to be patient to discover more nodes

I cannot figure out how to mine any ALT currencies with my ASIC USB miner and CGMiner...most of them use scrypt and when i try to use that with cgminer-nogpu.exe i get a "unrecognized option" error. Any help?

It's not possible. You can't mine scrypt coins with a sha256 ASIC.

I see...

[Balthazar]

We seen some phishing attempts.

Be careful.

just wake up then i was not sure but now....i am

WOW --- i guess intelligence or Computer competence is no prerequisite for being a senior member  in these forums... you haven't figured out the PRIMARY Reason the Script Coins were developed was to avoid the ability to be mined by ASIC devices.... WHAT are you stupid?  Blind? or Willfulling ignorant???  I have to wonder???

Minor client update is available.

v0.4.4.4

• Google's LevelDB support is implemented, and used as transaction storage by default*;
• The -nosynccheckpoints option is replaced with the new -cppolicy=mode option**;
• RPC: blocktrust and chaintrust fields added into block dump function;
• Many minor fixes and optimizations.

*) LevelDB is a low-latency data storage, optimized for multiple write operations. DB engine works in a separate thread, this also could improve wallet performance.

**) Possible values:

• strict - default mode, verify blocks to satisfy syncronized checkpoints, and reject if necessary;
• advisory - verify blocks to satisfy syncronized checkpoints, and display warning if necessary;
• permissive - don't perform any checkings.

That's a good idea, but you must tell us what the upper limit is (not everybody is a programmer).

It's not ready yet, that's why there is no full explanation at the moment, but it's quite simple. Just one example, if you have two options:

• 1000 coins input
• 10 x 100 coins inputs

there will be no difference in profitability, which is wrong.

Smaller inputs should be prioritized, because it's significantly better for the network, that's why we need this upper limit for the reward. To make sure that there will be no malicious stakeholders, which are able to manipulate by PoS difficulty through using larger inputs instead of smaller ones.

Have you decided yet what the upper limit is?

[Balthazar]

Have you decided yet what the upper limit is?

This limit is set to 10 coins, but inactive until 20 Oct 2013. According to result of our analysis (and independent results too), it's an optimal value.

But we are also working on alternate solution. It's a dynamic computation of the reward limit, based on PoW difficulty. Maybe this function will replace a static limit in the future, but I don't think so.

I don't see the point in dynamic function as well.

Experimental native build for 64-bit Windows is available.

Make backup of your data folder before trying this build. Reports are welcome.

Tested for a few hours... It seems that this build is stable enough.

Any advantages to 64bit client?

[Balthazar]

It works slightly faster and able to function in the pure 64 bit environment, e.g.

• 64-bit WinPE;
• Windows Server Core without WoW64 layer installed.

[Balthazar]

Windows 64-bit build is updated.

Installer (don't forget to remove previous build before): http://sourceforge.net/projects/novacoin/files/experimental/novacoin-setup-win32-amd64-0.4.4.4.exe/download
ZIP: http://sourceforge.net/projects/novacoin/files/experimental/novacoin-0.4.4.4-win32-amd64.zip/download

• Slightly lower memory consumption;
• No LevelDB abstraction object recreation during the checkpoints handling;
• ~ 10% faster block index object initialization.

MinWG64 adapted branch published:

https://github.com/CryptoManiac/novacoin/commits/novacoin-win64

There are some OutputDebugStringF related warnings yet, will deal with it later.

P.S. Thinking about the ZeroCoin integration.

I'm getting the following after building 0.4.4:

Code:

novacoin-qt: src/kernel.cpp:393: unsigned int GetStakeModifierChecksum(const CBlockIndex*): Assertion `pindex->pprev || pindex->GetBlockHash() == (!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)' failed.
Aborted (core dumped)

[Balthazar]

Rebuilt just now with leveldb and bdb, the both builds are working fine. And BDB build successfully loaded with 0.4.3 client database.

Can you publish your data folder? Except for wallet.dat, of course.
