[ANN][Datacoin] Datacoin blockchain start announcement (Minor code upd + logo)

[Chicago]

The other issue with upgrading is Segwit.  I understand it will make easy cross chain exchange with other Segwit coins like Bitcoin and Litecoin.

That entails a long running jump and grab to an 0.14.2 Core clone. And a hard fork. That's quite a big “ask”.
Right now, I'm trying to get a sense of the role that Datacoin's unique strorage feature plays in the overall functioning of the coin.

Hi Graham, Extro,

    I agree the move to an immediate v0.14.2 Core clone is premature.

    If porting Datacoin's unique storage feature as a new script opcode into a plain Core clone becomes an understood process - - then perhaps we're left with just two more pieces.
    The first would be bringing in the proof-of-work method employed by Primecoin/Datacoin and the second would be the implications the additional Datacoin script has on transaction/block creation/verification.

    Somehow I don't think we can achieve the latter without having first mastered the former.

    Advance the Datacoin code with the primary goal being the preservation and re-usability of upstream Core's battle-tested implementation of the various branches.

    I'd imagine the experiments would start by taking 0.8 Bitcoin/Litecoin and doing a big-bang with the additional script.
    So long as that tests well for doing everything Datacoin does today -- then experiment #2 would probably be another iteration of experiment #1 which employs the Datacoin/Primecoin proof-of-work algorithm.

    After that tests satisfactorily; then a next experiment should be attempting to verify the current entire blockchain using the work from the previous experiments.
    After that tests satisfactorily; then probably coding in the same Network Magic and other parameters to try and not be DoS banned by existing Datacoin clients would reveal where we are succeeding or have further work to perform as we connect it to the peer swarm for the first time.

    These are just some initial thoughts on how to move forward in the absence of Primecoin upstream development.

Best Regards,
-Chicago

Hello,

    Yes, there are several.  Have a read through the last few pages of this thread to find a few links.

Any further advice on how to get Datacoin onto exchanges would be very welcome.

Exchanges need a solid network before they will consider datacoin. They can't risk chain being attacked. Difficulty is rising fast now but we still need more nodes mining to secure network. 51% attack still quite possible even for individual at current level. We need high enough difficulty that someone with garage full of GPU rigs can't touch. Then exchanges will be able to consider other factors.

If porting Datacoin's unique storage feature as a new script opcode into a plain Core clone becomes an understood process - - then perhaps we're left with just two more pieces.

I wasn't planning to take that route. The Datacoin approach is reasonably straightforward, uses an extra field in the CTransaction object, no impact on the opcode/scripting at all (afaict). Or have I missed something critical?

I'd imagine the experiments would start by taking 0.8 Bitcoin/Litecoin and doing a big-bang with the additional script.

Even better, gatra's Riecoin is a primes-as-proof-of-work clone of straight Bitcoin 0.8.3, not a hint of “ppcoin” anywhere in the sources and a very useful set of version branches.


  remotes/origin/0.10.2
  remotes/origin/0.6.2
  remotes/origin/0.6.3
  remotes/origin/0.7.2
  remotes/origin/0.8.1
  remotes/origin/0.8.3
  remotes/origin/0.8.4
  remotes/origin/0.8.5
  remotes/origin/0.8.6
  remotes/origin/0.8.6-ric
  remotes/origin/0.9.1
  remotes/origin/0.9.2
  remotes/origin/HEAD -> origin/0.10.2
  remotes/origin/blockheaders
  remotes/origin/freenode-verf
  remotes/origin/master
  remotes/origin/master-ric


So, I was able to upgrade foo1inge (via Primecoin) to 0.8.4 and 0.8.5 and then pull up to 0.8.6, at which point I was able to shimmy over to 0.8.6-ric, pick up the (albeit Riecoin-specific) primes-as-PoW architecture, then take a long running jump and grab to Datacoin 0.9.1. Which is where I am atm, cross-referencing against a Minkiz Foundry 0.9 Bitcoin Core template (to identify common change points). At this point, the refactoring of foo1inge Datacoin-specific code is still significantly incoherent with respect to the 0.9.1 base, so the next step is a cross-comparison of Datacoin vs its original cloneparent at the point of cloning - to more precisely delineate the original footprint of the Datacoin-specific changes and use that as reference for the final refactoring of the Datacoin code so that it is coherent w.r.t to an 0.9.1 codebase. It should only be a standing jump to 0.10 from there, iirc. And the only remaining Prime/PPcoin code will be limited to that which is required by the Datacoin-specific PoW routines, i.e. not a lot.

Cheers

Metadisk used to work with Datacoin as well.  But I think it was changed to Florincoin.  Maybe someone should bring it back

Graham you are amazing.

Graham you are amazing.

And also full of bullsh*t, I've spent most of my life trying to figure out which is which. Let's see if I can actually deliver this.

Hello Datacoin Community!
I just recently stumbled on your project, which looks really interesting and was abandonded (same way like we experianced with Slimcoin, where I'm personally involved).
And we also have now same contributor (I would say developer, but Graham always say he is 'contributor', I think it's a big modesty from him),

I came here with maybe strange and crazy idea, but nonetheless, I thought, that I should say it here. What about merging our 2 projects into 1. I know that's a lot of work to do, we have different codebases, based on different coins (our on Peercoin, yours on Primecoin), different goals and aims, but together we could do a lot of more. We could also burn Datacoin and Slimcoin , and swap it to a new token (but more as a continuation of Slim, because we have support of an exchange, and some volume on it), or just create a new fork of it, (still old holders of Slimcoin and Datacoin should be rewarded proportionally) and let both still co-exist, but personally I would prefer, to burn (and reedem appropriate % to both projects, because supplies and market cap of both are quite different), but both of these approaches, would inherit great advantages of these 2 projects - Proof-of-Burn consensus and 128kb tx rich information and other tweaks, which could enable truly decentralized web come true. SlimData
I know it's some daydreaming (or might be a night for now), but I had this beautiful dream in front of my eyes today . Tell me what do you think (if you don't like it bash me straight, don't sugarcoat it).

Edit: can someone point me to valid miner with newest repo? There was quite a few, and I don't know which is good (for Windows), also http://datacoininfo.org/, has not working link to miners.
Is miner in the client optimized or there are other better optimized? Which fork of client I should be running? foo1inge or other/s?

Edit2: someone just have took oportunity to change ticker name to DATA
https://blog.streamr.com/2017/08/announcing-the-streamr-datacoin-ico/

Edit3: if idea with SlimData won't work (would be burned  ), is someone interested trading Slimcoins for Datacoins? PM me.

I'll start my old pool in 1-2 days I hope :-)

I had some time yesterday, so it should.
I don't have any running AMD rig, so I can't test it right now, testers are more than welcome :-)
Payouts should be made after full confirmation - 3200.

It works as before, just what is the Target now? Is it still 9?

Target is as before, 10.
Shares paid are 7,8,9,10+
As mining establishes and number of shares on confirmed blocks will count and payout per share of 7,8,9 will auto adjust.
In free time I'll try to make more dynamic system, based on current diff, not hardcoded as it is now.
It is old project, I'll need to look deep into it :-)

It looks like the environment at BTCPOP Exchange (https://btcpop.co) is favourable for the listing of new coins. 

I posted on the Coin Suggestions page.  https://btcpop.co/forum/viewthread.php?id=1618
The moderator seems quite active, so please add your voice on the thread in favor of Datacoin.  Also answer any questions or gripes they may have.

If anybody has had any experience with this site please share it.

Thank you.

Can't you get on nova/cryptopia ? Just not yobit, this scam exchange is so bad.

Good find ... (I think)

The side-channel analysis is quite favourable. I'm comfortable with the non-nonsense stance - a Marshall Islands reg, no pretentiously misleading bogus T&C's. Reading between the lines, the most prolific blogger seems to be the manager. Maturity is evidenced in the writing style and approach. Capability is evidenced by the content, I find myself professionally interested in the (albeit under-powered) attempt to use textual analysis to beef up the p2p loan risk assessment.

I shall register, see how we get on.

I cannot register on Nova.  For the last 3 days or so registration has been disabled.

Registration on Cryptopia will effectively cost 2-3 Bitcoin.  We need to buy 1 200 000 of their "DOTS".   I want to see if we can get a free registration before we go for that kind of money.

Once we are registered I will go for a modest media campaign on Cryptocoinnews, Cointelegraph, The Merkle etc.  Hopefully that will attract more exchanges to us, rather than we having to pursue them.
