[POK] Pokercoin Reboot - 100,000 POK Premine DESTROYED! - new: 5 Cards per Block

[Lauda]

It shouldn't have been rebooted.
Let the crap die.

If you started the blockchain from zero why didnt you just alter subsidy function to get rid of special reward of block 2?

Because that would require a fork and new clients for everyone.    This way was quicker, and still lets all the version 1.0.0 clients participate.

Last time I checked, the bitcoin reference client tested for MAXIMUM reward, not minimal, so you can mine blocks with less or no reward.

Is this somehow changed or why did you kept the complication when restarting?

Why? there is already a CasinoCoin.

Pokercoin has less value, it can be only used for poker, Casinocoin in more universal

I think this would be better named as SolitaireCoin.  After I compiled a windows wallet (since one wasn't provided) and mined for a bit, I soon figured out I was the only one sitting at the card table mining.  So I quite mining after a couple blocks but came back a few hours later to see if there was any new action.  No signs of anybody sitting at the card table and saw that no hands were even dealt since I left.

Hmm... you may be right about checking only for greater rewards, not less:

Code: (https://github.com/superblocks/Pokercoin/blob/master/src/main.cpp#L1441)

    if (vtx[0].GetValueOut() > GetBlockValue(pindex->nHeight, nFees))
        return false;

I'll have to remember that for the next dead altcoin reboot

Although it doesn't seem as dramatic and easily validated as sending the premine to a destroyer address.

Sometimes the table is very slow, sometimes there are a few players.    One or two have been active lately for sure, driving the block height up to #8375 and climbing.   Difficulty currently at measly 0.008.

(and note that the old version 1.0.0 clients still work on the rebooted chain)

so this is how bitcoin mining looked like a year ago.. easy coins..

New! - Pokercoin 1.0.2 code now released!  See https://github.com/superblocks/Pokercoin

This update adds a checkpoint at block #15000, and a new rpc command: getcards.

getcards draws 5 playing cards based on a block hash.  It's also added to getinfo, based on the current block hash:

Code:

    "blocks" : 15691,
    "cards" : "Ace of Diamonds, Queen of Spades, 8 of Diamonds, 10 of Hearts, 4 of Hearts, ",

Example usage:   Get a hand from the pokercoin genesis hash:

Code:

# ./pokercoind getblockhash 0
5b08cbe328392be8151f5deec2dc92e7609dcbd20e0dac335904ccf538df68e8

# ./pokercoind getcards 5b08cbe328392be8151f5deec2dc92e7609dcbd20e0dac335904ccf538df68e8
5 of Hearts, Queen of Hearts, 2 of Hearts, 3 of Hearts, 2 of Hearts,

The getcards command will take in any well formed hash: 64 chars long, only hexademical characters.

Cards are determined by splitting the block hash into 2 character segments.  For each segment, first character is the card, and second character is the suit.  Here's the code to show how the cards are decided:

Code: (https://github.com/superblocks/Pokercoin/blob/master/src/bitcoinrpc.cpp#L403)

//
// Get a Playing Card - version 0.0.1
//
std::string getcard( char c )
{
    switch( std::tolower(c) ) {
        case '1': return "Ace";
        case '2': return "2";
        case '3': return "3";
        case '4': return "4";
        case '5': return "5";
        case '6': return "6";
        case '7': return "7";
        case '8': return "8";
        case '9': return "9";
        case 'a': return "10";
        case 'b': return "Jack";
        case 'c': return "Queen";
        case 'd': return "King";
        default: case 'e': case 'f': case '0': return "Joker";
    }
}

//
// Get the Suit of a Playing Card - version 0.0.1
//
std::string getsuit( char c )
{
    switch( std::tolower(c) ) {
        default: return "ERROR";
        case '0': case '1': case '2': case '3': return "Clubs";
        case '4': case '5': case '6': case '7': return "Diamonds";
        case '8': case '9': case 'a': case 'b': return "Hearts";
        case 'c': case 'd': case 'e': case 'f': return "Spades";
    }
}

//
// Get a Hand of Playing Cards - version 0.0.1
//
std::string GetCards( std::string hash, int limit = 5 )
{
    if( hash.length() != 64 ) { return "ERROR: hash is not 64 chars long"; }
    std::string deck, check;
    int count = 0;
    for (int i = 0; i < hash.length(); i+=2) {
        check = hash.substr(i,2);
        if( check[0] == '0' || check[0] == 'e' || check[0] == 'f' )
            continue;
        deck.append( getcard(check[0]) ).append( " of " ).append( getsuit(check[1]) ).append( ", " );
        count++;
        if( count == limit )
            break;
    }
    if( count != limit )
        deck.append( "ERROR: not enough valid cards in the deck" );
    return deck;
}


//
// Get a Hand of Playing Cards - RPC call - version 0.0.1
//
Value getcards(const Array& params, bool fHelp)
{
    if (fHelp || params.size() != 1)
        throw runtime_error(
            "getcards <hash>\n"
            "Returns a hand of playing cards.");

    std::string strHash = params[0].get_str();

    return GetCards(strHash);
}

All very beta and  proof-of-concept now, but may be something that can be built upon for gaming

No pool yet.   If someone were to set one up, I'm sure there'd be bounty coins for it.

On this forum?     There's no exchanges yet that support POK.  If some pop up, they are sure to receive bounty coins.
