[ANN] [CHC] Chaincoin - Network Upgrade 16.3 - SegWit Activated

[OhShBit]

This coin has some great qualities, and no pre-mine.. We need some games or services for it.

This coin trying to use CHC even though ChainCoin has it and listed on exchange.

Yeah, but there is that little thing of Chaincoin having the CHC acronym almost 5 months before Choiccoin started. So yeah, there is that..

CPU COIN LIST
Cryptocurrencies for Your Processor

Follow us on Twitter!

ChainCoin has been added to The CPU Coin List.

I am trying to complete the entry. Does anyone know the Difficulty Retarget time?

[gjhiggins]

I am trying to complete the entry. Does anyone know the Difficulty Retarget time?

The usual suspects assert it as 1 block, or 90 seconds:

https://github.com/chaincoin/chaincoin/blob/master/src/main.cpp#L1273

Code:

static const int64 nTargetTimespan = 90; // 90 seconds
static const int64 nTargetSpacing = 90; // 90 seconds
static const int64 nInterval = 1; // Chaincoin: retarget every block

But ofc, only a detailed inspection of the code can give you a canonical answer.

Cheers,

Anyone know what's going on with the wallet? I'm getting "No block source available". I've added all the nodes that were listed, and I've installed it on another machine as well with the same error..

Sorry, but could I press you for some more detail on "help me out" ...

According to the github repos, Chaincoin is a clone of Zetacoin, itself a clone of Bitcoin 0.8.2, which doesn't offer getnetworkhashps.

To get that functionality, the  feature would need to be copied across from say, Litecoin 0.8.6.2.

And I was curious whether this was as straightforward as it appeared and that does indeed seem to be the case:

https://github.com/gjhiggins/chaincoin/commit/863404d4d55ce1995022e4fae320b85ac8ad8e91

So, I can report the following initial results, lord knows whether they're accurate or not, does 4Mh/s sound about right for what's basically x11?

Code:

gjh@ashpool:~/minkiz/coinage/coins/ChainCoin.bis$ ./chaincoind -daemon
Chaincoin server starting

    "paytxfee" : 0.00000000,
    "errors" : ""
}

ta-da

Code:

    "networkhashps" : 4829498,

Hi Graham,

As for the "help me out", you already have. I wasn't sure where to start addressing the issue, but you have clarified it perfectly.
I have used your commit to recompile my daemon and it work like a charm. I had seen that someone had already figured it out here:
http://www.cryptocoinsinfo.com/statistic/coinstat.php?coin=10566 so I thought I would just ask hoping to get an answer
like the one you have provided. Thank you!  If you want to post or pm me your chaincoin address I would be happy to send you some.

As for my interest in Chaincoin, I think it is a good coin that got overlooked because of the whole coin boom.
It is unique, with no premine and was not a coingen creation. Although, technology connoisseur, historian, hodler would be an accurate
description as well..

Regards!

Edit: I would like to set up a couple of abe block explorers, too. Although, I have to figure out how to get the parameters of the Chaincoin network..
I am a noob to this, any help is very appreciated.

e.g.   {"chain":"Chaincoin","code3":"CHC", "address_version":"?", "magic":"?"},

If anyone could help me out with the net hash input for this crawler I would be very grateful.

{"chain":"Chaincoin","code?":"CHC", "address_version":"?", "magic":"?"},

My reading of the runes prompts me to suggest the following config:

Code:

{
  "chain": "Chaincoin",
  "code3": "CHC",
  "address_version": "\u001c",
  "magic": "\u00a3\u00d2\u007a\u0003"
}

For the code3 value, I always consult the source code directly, for canonical accuracy: https://github.com/chaincoin/chaincoin/blob/master/src/qt/bitcoinunits.cpp#L37

address_version is the JSON representation of the hexadecimal representation of the decimal integer which maps to the specified address prefix / leading symbol, i.e. "C" for "Chaincoin". (No, really, I am not making this up).

Here's the necessary map of leading symbols to decimal integers: https://en.bitcoin.it/wiki/List_of_address_prefixes. It yields 'C' = 28, the integer value that is bound to PUBKEY_ADDRESS in https://github.com/chaincoin/chaincoin/blob/master/src/chainparams.cpp#L72

A spell of "render unto JSON" is described in the Abe FAQ https://github.com/bitcoin-abe/bitcoin-abe/blob/master/doc/FAQ.html#L64; in this specific case, decimal 28 becomes hexadecimal 1c and then that is rendered as JSON by prefixing with a backslash, a lowercase u and a coupla zeroes - thus "\u001c" in the JSON code above.

By "magic", I'm guessing that they mean the sequence of four hexadecimal numbers which together form the content of the message start string "pchMessageStart": https://github.com/chaincoin/chaincoin/blob/master/src/chainparams.cpp#L26 ...

Code:

        // The message start string is designed to be unlikely to occur in normal data.
        pchMessageStart[0] = 0xa3;
        pchMessageStart[1] = 0xd2;
        pchMessageStart[2] = 0x7a;
        pchMessageStart[3] = 0x03;

Those four hexadecimal numbers (a3, d2, 7a and 03) are rendered as JSON in the manner described above and the results concatenated (preserving the order), i.e. "\u00a3\u00d2\u007a\u0003".

I haven't tested it, so it's only my best guess. I took my bearings on "magic" from the Abe config for Litecoin given here http://www.jevon.org/wiki/Litecoin which matches precisely the Litecoin pchMessageStart value: https://github.com/litecoin-project/litecoin/blob/master-0.8/src/main.cpp#L3082. Seems a safe bet.

HTH.

Cheers,

Graham

[OhShBit]

Thank you for all of this great information. Although, I have not been able to utilize it fully for the block explorer.
I'm stuck with an error during the installation. It calls for some random module when I initially launch abe.
I tried to use this howto: https://cryptocointalk.com/topic/1312-luckycoin-blockchain-explorer/

I would really like to know how to set these up, but there doesn't seem to be any straight forward instructions
on how to accomplish this. At this point I am willing to give a bitcoin bounty if someone could write up a better
setup guide for abe. Preferably one that acknowledges all dependencies and addresses any possible contingencies.
I haven't given up, but I have a feeling that I won't be able to proceed any further without some type of intervention.

At this point, I'm still willing to take any suggestions on how I could fix this.

Thanks again for all of your help.

Code:

{"chain":"Chaincoin","code?":"CHC", "address_version":"?", "magic":"?"},

My reading of the runes prompts me to suggest the following config:

Code:

{
  "chain": "Chaincoin",
  "code3": "CHC",
  "address_version": "\u001c",
  "magic": "\u00a3\u00d2\u007a\u0003"
}

is the coin dead?looks like,lol

yup dead as can be no dev or support

I think it's funny how people think they are experts on altcoins. Less than 6 months on the boards
and this is the most intelligent thing you two have to say?

Github updated with a checkpoint.

Difficulty is low, still plenty of Chaincoin's to mine

Criteria for a coin to be added to coinmarketcap.com
Must be a cryptocurrency - check
Must be traded on a public exchange that is older than 30 days and with an API available - check (coinmarketcap supports allcrypt now)
Must have a public URL that displays the total supply (total mined so far) - ?

Can somebody provide this link? We can get into coinmarketcap easily
