If anyone is still having issues syncing after adding in new nodes, try rebuilding the blockchain with
the reindex flag.
Just add -reindex to the end of the target path of your datacoin shortcut
 \datacoin -qt.exe -reindex

fwiw dept:

I've pointed my home-grown “ACME” block explorer at my datacoin node and it's returning basic block and tx info. Addresses remain problematic and I've yet to add the data explorer.

Give me some dtcs: DAUwp8GkvXL5PkDXFx5YvWE585XKBHL3Ux
I want to write something on this blockchain. Trying solo-mine but no luck.
There's no pool nor exchange, so what can I do? I can pay 1000 sat/dtc.

Hello,

    I wanted to put this out there for those who are interested in and loyal to this project.

    Today, I see 19 connections on the network.

    This is _really_ good for a coin without any promotion and without an active thread.

Best Regards,
-Chicago

There's the DTCBrowser and Apertus linked to this coin.  On Github.  And there is Bytestamp.  Some of them mine the coin, so there is enough to keep it going.

At some point I believe another developer will take over and the coin will be listed on an exchange.  I keep on mining it.

Hi yahoo-fiurejf9,

    Here are the full nodes as of today, from my observation point.

        45.77.30.227
        [2001:19f0:7001:7fb:5400:ff:fe6e:a871]
        144.76.64.49
        139.162.210.78
        [2a01:4f8:191:7330::2]
        71.239.112.232
        [2001:558:6033:87:956a:244e:c4ab:e7b]

    You may want to update your init.sh commit since many of the addnode entries you have included there are externally inaccessible.
    There is no need to add a port number for the above hosts since they all listen on the official peer port, 4777.

    Thanks for your work.  I'm looking forward to hearing of a new user who benefits from your actions today and has a more simplified onboarding experience using Datacoin.

Best Regards,
-Chicago

Trying to add Datacoin to Bitsquare Exchange (https://bisq.io).

They need:

* Ticker symbol (e.g. BTC): ....
* Official coin name (e.g. Bitcoin): ....
* Official altcoin webpage where Bitsquare will be added as official exchange: ....
* URL of the block explorer: ....
* Example address (e.g. 3MPe1LfMeJvumN7ykswSwkPSoXLbheXnCH): ....
* Confirmation that you have checked that the ticker does not conflict with https://en.wikipedia.org/wiki/ISO_4217121 and https://coinmarketcap.com/currencies
* Social media accounts like Twitter account, subreddit, etc.: ....

Can we provide this?

Submitted to Bitsquare.

I understand another official website would be http://datacoininfo.org.

I understand we need to do a pull request to the exchange to have the coin added.

Empoex trading Datacoin.

Hi extro24,

    Nice find, I'm curious how others rate Empoex.  Today is the first I've heard of it.
    Looks like there is nearly 1 BTC worth of buy support there at present, for 144 Satoshi per Datacoin.

    The real neat thing is it looks like back around March of this year, someone traded less than 20K DTC for more than 0.5 BTC.


    EDIT:  That's DayTraderCoin and not Datacoin!

Best Regards,
-Chicago

Woops!

Sorry.

coinmarketcap don't seem to notice:

https://coinmarketcap.com/currencies/daytradercoin/ “DayTraderCoin (DTC)”

https://coinmarketcap.com/currencies/datacoin/ “Datacoin (DTC)”

There's an opportunity to acknowledge the conflict and generously switch Datacoin (DTC) to the unoccupied and definitely safer from future trading symbol clashes Datacoin (DATA).

Cheers

Maybe somebody can help.

I was chatting to Embii on the Facebook page of Apertus.io.  He mentioned that they are able to get Javascript programs to run on Datacoin but only with the 20byte payload, not the full 128kB payload.  They can write the data, but no other client can read it.  With the 20byte payload it is very expensive to write Javascript programs into the Datacoin blockchain (you need to pay 0.05DTC for every chunk of code that gets written and with 20bytes you need a lot of chunks).

From embii:
"we implemented encoding and deciding base 64 for DataCoin...we did get this to work...except what is saved in this manner is only accessible via RPC to the wallet that saved it... this is the real problem and is the main reason we abandoned it. It does have personal applications but does not let you share anything saved with others."

I tried to see if I could find the problem in the Datacoin wallet.  In rpcwallet.cpp I saw

senddata(const Array& params, bool fHelp)
{
if (fHelp || 1 != params.size())
throw runtime_error(
"senddata [data]\n"
"<data> is a base64 encoded data chunk"
+ HelpRequiringPassphrase());

CWalletTx wtx;

// Transaction data
std::string txdata;
if (params.size() > 0 && params[0].type() != null_type && !params[0].get_str().empty()) {
txdata = params[0].get_str();
if (txdata.length() > MAX_TX_DATA_SIZE)
throw JSONRPCError(RPC_INVALID_PARAMETER, "data chunk is too long. split it the payload to several transactions.");
}

string strError = pwalletMain->SendData(wtx, false, txdata);
if (strError != "")
throw JSONRPCError(RPC_WALLET_ERROR, strError);

return wtx.GetHash().GetHex();
}


I suspect HelpRequiringPassphrase() is the suspect. Anybody else have an idea?  We will have to remove this so that other wallets can see the 128kB data in the blockchain.
If this can be done the Datacoin blockchain will contain Javascript programs that will be visible to other clients and executable in the Apertus.io browser.  And maybe other browsers as well.  Datacoin could then use Javascript as a programming language.

That is a good idea and together with javascript implementation.
Then there can be future for datacoin!

Hello,

Code:
std::string HelpRequiringPassphrase()
{
    return pwalletMain->IsCrypted()
        ? "\nrequires wallet passphrase to be set with walletpassphrase first"
        : "";
}

    I see this in src/rpcwallet.cpp.

    Are you telling me the ~128KiB data blob is only accessible with the private key of the spender and that the wallet.dat must be encrypted too?

    If so... couldn't there be some work-arounds where an M-of-N Datacoin address could be employed to make the ~128KiB blobs available to anybody at the time of publication whereby the publisher says, "BTW, here's the WIF for those so you can decode them."

Best Regards,
-Chicago
