Hi dev!
i started dtcclient_v10.0beta on gtx1080.
but i got error "OpenCL error: -42 at /HDD/build/projects/xpmclient/xpmclient/xpmclient.cpp:1063"
How can i solve it?
thanks

oh i got work @dtcclient_v10.1beta!
thanks

For next readers:
For Pascal cards best use 10.1 version.
For older AMD cards older versions seem to give better CPD.

Atomic Swaps

I was fascinated to see that the atomic swaps between Bitcoin, Litecoin and Decred involves only Script (a derivative of Forth).  No SegWit or Lightning is needed.  "btcatomicswap", "ltcatomicswap" and "dcratomicswap" have been created.  See https://github.com/decred/atomicswap/
Datacoin (and Primecoin) still has Script, so in principle it should be possible to create a "dtcatomicswap" tool.  This is interesting, because it would mean we could do atomic swaps between BTC, LTC, DCR and DTC.

muf18 that was 5001 followings.  Amazing what your fingers can do if you are motivated.
Twitter stopped me from following any more.  I wanted to go up to 10 000.  But what is interesting is that the number of followers are now going up nicely by themselves.   I think we will hit 2000 followers by next week.

Nearly all those followers are crypto people or finance people.  I avoided the followme/followback crowd, although one or two did creep in.

For Slimcoin I suggest you start following.  And do automated tweeting - it helps a lot.

With luck and a following wind (or more specifically, a re-install of brew) an OS X version of the not-new-at-all client will be available soon.

Again, more informality to be tolerated, an OS X binary of the not-new-client is available on https://minkiz.co/noodlings/dtc/Datacoin-Qt.dmg

When I cut a release, I'll re-mill the binaries and make them downloadable from the Github repos.

Cheers

Graham

Thank you Graham.  I put it on our list of clients.

As an aside, we now have 1288 Twitter followers. I think we are getting somewhere.

After spammy follows you achieved it Wink.
5000 follows, I don't know how you managed to do it...

Having just had to talk down extro24 off've the ceiling ...

What's in my repository in the master branch is a straightforward clone of the foo1inge repos, with a few simple fixes so that it will compile on modern OSes. Any talk of a “new client” is misleading.

It's not new, it's the old client that was working, is still working but which we can now compile fresh versions of, which we couldn't before because the codebase had aged in comparison to the OS that host it and the libraries which give it its functionality.

Those libraries have been developed further since Datacoin was launched but the codebase hasn't been kept up to date with those developments. In particular, an infelicity in the boost 1.68 library causes the compiler to reject a line of code in rpcrawtransaction.cpp, causing the compilation to fail.

Elsewhere, developments in C++ have obsoleted the old C99 PRI* macros used for marshalling data into print routines, depending which distro you're using, it's  deprecated and results in a wall of compilation warnings that can dangerously obscure other, more important compilation warnings such as the deprecation of auto_ptr, so it's worth a s/"PRI/" PRI/g to get rid of them.

The “proper” fix is removing them entirely, C++ has acquired the ability to handle them directly so strprintf("database.%" PRI64d ".bak", GetTime()); becomes just strprintf("database.%d.bak", GetTime());. This work will take place in a separate branch, to be subsequently integrated into the master branch.

On OS X Sierra (or, more accurately XCode > 7 iirc) and very recent Linux distros, the C99 PRI macro and auto_ptr uses are no longer deprecated, they are now compilation-stoppers.

Aaanyway, none of this is profound, afaik they're all trivial from a software engineering perspective and have all been addressed in a single commit, so that everyone can see what I done and, if they have objections, can voice them:

https://github.com/gjhiggins/datacoin/commit/1ff346f1d1dea96b3885063490c2d134889f045d

or even clone the repos, make their own candidate changes (community acceptance is the final arbiter) and issue Pull Requests to have the changes integrated into the master branch (generally the branch where all the agreed-as-successful development work ends up).

Periodically, when things are quiet and it's a suitable phase change point, a “release” can be cut, i.e. the current master branch gets copied into to a “release” branch and its availability advertised. Work on the “master” branch continues until the next phase change point is reached and another release cut,

Feel free to get a Github a/c so you can raise issues and have input into any strategic or tactical discussions that take place.

So, the code in the “construction site” branch is in smithereens and is not the same as the code in the master branch and, as it logically has to be, the Windows binary is compiled from the master branch, as the code in the construction site branch will not yet compile at all.

With luck and a following wind (or more specifically, a re-install of brew) an OS X version of the not-new-at-all client will be available soon.

HTH

Traded datacoin back in the day, one of my first altcoins.

There are no new clients yet, correct?

Correct. There is a construction site on https://github.com/gjhiggins/datacoin/commits/datacoin-hp14 but the code won't yet compile, let alone run. The codebase in a “jig”, being painstakingly cross-matched, difference by difference, resolving each one in favour of the to-be-upgraded version, where the difference isn't one of definition e.g. adjusting the Datacoin code to use the new CAmount object instead of the native uint64_t (not actually an example, just imitation CBabble) while paying special attention to preserving the prime-sieving math routines that basically define Datacoin - and then working out how to best refactor them to fit the new codebase.

It's speculative work and there's no guarantee of success (but then again, the latter is a general condition imposed on us all by the space-time continuum in which we exist so it isn't saying anything that you don't already know, deep in your bones).

Cheers

Graham

P.S. I've actually taken a temporary step “backwards” into the test directory. Looks like the code's never been changed from the Primecoin original, so the first thing I've done is adjust the base58 key fixture generation so that the code is being tested against Datacoin addresses and priv/pub keys. I'll be pushing those commits up the line as I finish them. I'll add a Travis CI config file and trigger its continuous test facility --- tests are automatically run after any new commit to the repos.

Edit - updated link to be more specific and link directly to the separate branch in which the “construction site” is lodged

How to mining using CPU?

Open the console/debug window, type setgenerate true into the box where the number of threads/cores you wish to dedicate. The console window also knows help as a  command. setgenerate false stops all processes dedicated to “mining” (actually, prime number generation in Datacoin's case).

the github says “This file may contain malware and the automatic download has been disabled”,and the file is too old now.i think new wallet may be needed

If you can tolerate the informality, I have an MXE cross-compiled Windows binary available. All I had time for was to check that it runs on a Windows 10 VM, mind you. And I couldn't manage to successfully compile the qrencode facility, so I had to disable it pro tem.

And privacy, who guarantees that your data will actually be saved and privacy? Well, I'm not criticizing the project, more privacy is above all else.

There's no restriction on what is stored, if you wish to store encrypted data for maximum opacity. Data is saved when the block is mined, for a fee. It's a transaction, subject to the usual rules pertaining to transactions.

Cheers
