great job，a new version

Good day!

The block was rejected by old clients of main network and client temporarily banned for misbehaving. Previously generated few blocks was accepted successfully.
Can someone give me the reason of rejection and misbehaving from your logs?

Before embedding gpu miner I need to resolve this issue.

Verionum,

I have sorted the problem - I forgot to install autoconf on the server,

All versions - 0.15.99-03 / 0.15.99-04 / 0.15.99-05 and 0.15.99-06 compiled on Ubuntu 16.04 x64

Tnx,

H

Updated binaries and sources.

Source code DTC 0.15.99-06: https://yadi.sk/d/Vnkrnl1q3V2rnw
Windows binaries 0.15.99-06: https://yadi.sk/d/Zrb-2B7u3V2rrM

CPU miner from XPM-hp14 added. Some other fixes.
Commands:
Mine on all CPU: setgenerate true
Mine on 4 CPU: setgenerate true 4
Turn off miner: setgenerate false

IMPORTANT: Backup your wallet before using it.

Sorry. I don't understand what the matter. Are you sure you have done $ ./autogen.sh and $ ./configure --with-gui=yes LDFLAGS="-L/home/veter/dbbin/lib/" CPPFLAGS="-fPIC -I/home/veter/dbbin/include/" LIBS="-lgmp -lboost_timer -levent_pthreads" ?

CPU miner is revived. But it's so slow ....

Primecoin is the target of some kind of Bitcoin--Primecoin activity...
Very peculiar:
https://twitter.com/BitcoinPrime_
Primecoin price has mooned -- but buyer beware.
(Note this is not an endorsement, just an observation --- as Primecoin is a relative of ours)

Downloaded 0.15.99.05 from https://yadi.sk/d/ghrCHoxA3Un8Cm

Installed 0.15.99.03 and 0.15.99.04 with no issues and on 0.15.99.05 this appear, any solution? I saw many references about this error, however, no solutions where mentioned.

Hi,

IMHO best way is to make main wallet software without non-general features, like GPU or CPU miner or server.
Miner or server software will change, optimalizations will come, maybe we don't want rebuilding - we want clean and elegant wallet, with as low AV software triggers as possible :-)
Nothing holds us from making another version with miners included, name it "dev wallet" for more "pro" crypto users.

M.

What I found with regard to Microsoft specifically is limited to Microsoft Security Essentials -- and that is the outlier in the bunch. Microsoft Security Essentials tends to quarantine whether or not the internal miner has been removed.

Other suites like Norton, AVG or Avast will happily allow an install after the internal miner code has been removed.

What we found during a test over the past week - is that a 0.8 branch clone with the built-in miner triggers 22 warnings from virustotal whereas a 0.10 clone with the internal miner commit backported sees just 3 warnings.

More work is needed to have a comprehensive data set for how the various other anti-virus software reacts, but the pattern is already clear, speaking to me through the data; when a miner is builtin the masses get told to beware and the software gets removed.


Things like leaving the reference client alone w/ just a getblocktemplate and adapted miner for regtest should be fine.
It will be more maintenance to build in libraries from other projects which see updates more quickly than our own.

However -- everybody loves choices!
So we could maintain two flavors -- one with an expected trigger for experts where the A/V expectations are managed through trust --
and the other where the A/V expectations are managed by neutering the code to hold back a miner.

If we go that route then our website where the general public finds us - should deliver them an executable with great assurances it will be trusted by their security software.

At least qt-i386 doesn't conflict with Windows Def. Can't speak for the others though.

Oh please include the embedded server for external GPU miner. This is going to be very useful to keep the network healthy and attract more miners.
I'm burning to make a GPU mining video.
I'm just waiting for this functionality to be implemented in a future version, because this currently only works (as far as I know) on v0.1.2 gunk beta, which about 11% people are using.
(Kind of redundant having a new wallet plus an old wallet just for mining)

Sorry for inconvenience (and for my English :) ).

Of course blockchain the same. But index needs to be rebuilt. In this case it provokes resyncing. It happens once and no need additional resyncing in future.

0.15-0.16 versions of BitcoinCore (and Datacoin) client have another synchronization logic then old (0.8) clients.

For effective using this logic we need to send more data with HEADERS network messages (bnPrimeChainMultiplier fields).
Unfortunately old datacoin clients omit such data (fill it with zero).

In new version of my client I have updated this datacoin client logic. Now, instead of sending zero as bnPrimeChainMultiplier, it sends real bnPrimeChainMultiplier fields. But it requires to rebuilt index.

This change is backwards compatible.

Old clients without problem must receive this updated HEADERS messages. They just ignore  bnPrimeChainMultiplier fields.

This wallet don't work with old blockchain.
New synchronization is required.
Blocks have to be rebuilded.

I'd like to test these -- is anyone else having trouble downloading them?

Ope!
User error.
Testnet loaded, then synced with common swarm -- running additional tests now.

Honestly, at the beginning I did not quite believe in this project. But, having watched, I saw activity both here and in social networks, which means that investors' interest is growing.

Verionum - come to XCN thread maybe you would be able to update it's client as well. Or Slimcoin haha . This bitcoin 0.16 port is really good.

Updated binaries and sources.

Source code DTC 0.15.99-05: https://yadi.sk/d/ghrCHoxA3Un8Cm
Windows binaries 0.15.99-05: https://yadi.sk/d/auGBz2cO3Un8CD

Added code for convenient synchronization with other 0.15-0.16 clients.
Some other internal improvements.

IMPORTANT: Backup your wallet before using it.
