Someone sent a couple of large transactions at the MEC flip script today and there weren't any coins so the wallet couldn't even refund them.

Drop me a line if you want them back now that the transactions have cleared.

Betting limit is 2 MEC/bet and we have now added 100 MEC in house funds as well.

Now I see what you're saying.

There's still no guarantee that the transactions you have available can be assigned into a "super merkle" root though.

this is confusing me too.

You can't find a "winning" hash and then change the merkle root for the block you invalidate your hash.

I'm not sure what you mean by coinbase, the wallet address?  But, same same.  If you change the contents of the block the hash changes.

it sounds like you are talking about swapping out the merkle root or "coinbase" instead of the nonce?

Each block generated on the block chain creates a new "input" that input has to stay whole until it is broken apart.

So when you have a block found you don't really get X.XX coins you get an input valued at that number of coins.

Then when you spend it, it gets broken into "outputs" of various values according to the ssize of the original input and what you spent.

The piece you are spending is now owned by the receiver, and the rest of the split input is returned to your account.

Those outputs are held until you want to spend the coins, when the wallet selects from your available outputs something close in size to the amount you want to spend. The selected outputs are then used as the inpts for that spend, and the cycle continues, as each original input (coinbase) gets split into smaller and smaller outputs.

If you mined 50 12 XPM blocks on a machine, your wallet would say you have 600 XPM.  But what's really going on is you have 50 12 XPM outputs under your control.  IF you send them all to another wallet, the generated transaction will contain 50 inputs, and one output to the new wallet.

In this way the inputs are recombined so that we don't literally have to track an input/output for every fractional coin that has been re-used.

The wallet calculates a TX fee based on the size of the script required to combine the inputs into an output and return the change to the sending wallet. (ignoring some other factors like coin age).

This is why when I tried to send 20m IFC created from a ton of <100000 coin inputs I got charged a TX fee of nearly 10 IFC.

So someone that had mined a couple hundred blocks into one wallet and then tried to send all of their coins to a single receiver would cause a very large transaction to be written.

I hope that didn't add too much to your confusion

ok, no reason it shouldn't be showing I'm off to do a bit of research.

EDIT: 0 fee tx was a little slow to process but it's in now.

I don't understand.

Are you adding another 1m coins? 

I put a million coins int he IFC Coin Flip.

Max bet is 1000 coins, come by and give it a try!

NAN has been funded with 100 tokens, if anyone wants to give it a go.

Noted.

I've deleted a giant rant about coin devs and miners screwing each other and anyone who tries to interact with this community.

I'm not spending all week getting those coins added in so that you guys can tell me the exact same thing again next week.

It's become clear how this works and soon I may stop trying to develop for the alt-coin community at all. I've wasted now a couple of thousand hours learning how this works and all I ever hear is "it sucks it doesn't have my coin of the day on it".

It's getting impossible to take this seriously.  Maybe I should have been warming up on C++ instead and floating pump and dump coins with super blocks and other bullshit that's completely detrimental to the long term health or adoption of the coin as a currency.

Yeah, I'm wrapping this one up before I alienate 100% of my potential audience.

I would love to add all of the alt coins.

There is a cost to adding a coin and a cost to running it -  also I don't own the server.

For now it's not possible for us to "keep up" with alt coins as fast as anyone decides to release one.

We may review our list of coins soon as some of them are not performing and seem to lack any community.


No disrespect intended to any coin, or coin dev.  It's just a practical reality.

What do you mean by "fairly wide"?  I'm not talking about a little ntime rolling (if i have the name of that right).  I'm talking about ten blocks have come since that time. Reaching back 4-5 minutes.

I haven't dug that deeply into miner code.  Can you really allow that much flex in your time?  Is the client for primecoin using n-time rolling to generate blocks?  Bitcoin doesn't even do this it's an external miner function, right?

It just generates a load of questions.

Last time I looked it was <15

I'm a little nervous about this game it's more complex in the back end than the lotto is.  Thanks to whoever added the extra DGC and I hope this is fun. We'll see if the house just loses it all.

As this evolves I'm thinking about adding some other bets at different odds but I prefer a little variety over the "less than our number" games.

Maybe dividing the fields into smaller squares or some such.

A bet with a higher prize only if you come out above or below the house numbers.

Any ideas?  Also any math guys because somewhere in here odds cross probability and my brain gets tied in a knot.

For instance i can tell you what the odds are that a number from the possible spectrum will be generated. But what's the probability of the number being in the middle, and is it affected by how TXid's are generated?  No idea.  I'm also not sure if hashing the timestamp at the front or at the back of the address is more likely to larger variance in the output hash.

We're definitely gambling with you on this one.

Hey guys we're bringing a new game online today.

Coin World Crypto Coin Flip

This is a simple betting game right now it offers one option.

The game works like satoshi dice in that it hashes up some values from the transaction, calculates a number, and based on that number you win or lose.

The last 20 bets are streamed to the page, and each bet lists enough information for you to manually verify the calculation if you like.  The hashing code is on the page and the site is done in PHP.

AT THIS TIME the bet is not a simple "less than our number" bet.  I've divided the 65536 numbers into three fields so for ht eplayer to win the calculated value has to be less than 16084 or more than 49452 for the player to win.

There are an extra 600 numbers added to the house area simple calculations i think this means odds to win are 50.92% for the house.

I've done some testing on a couple of coins everything runs ok. Several scripts are yet to be funded, i don't have enough of all of these coins right now, and I'm afraid that with less than 1% odds in our favor and the house eating TX fees we're going to lose on this round.

In any case there is a funding address on each page. You can donate to the script to get it running if you want to try it out or see it work with your coin.  As we see how these odds work out we may adjust either the odds or the min/max on the flips.

VERY IMPORTANT:

Do not send bets to this script from a wallet that you don't own.  Much like mining or satoshi dice the address where your winnings are sent depends on the blockchain and in a shared wallet it may not be the address you sent the bet from.

This means that when you send from an online wallet service, or an exchange account, or any other wallet where more than one person share addresses - someone else is likely to get your coins.

This is not an error with the script, it's a function of how these coins handle inputs and outputs.

Infinitecoin has 1m coins in it and a 1k coin max bet, there's just a couple coins in DGC as well.

Tradecoin has some funds but the blockchain is slow and the site currently requires 1 confirmation to process.

I'm sure I might be missing a couple of points but I'm here for questions, if you have them.

I always wonder why the XPM block chain sometimes includes blocks out of order.

Why it would insert a block generated several minutes ago in to the current sequence.

Just something to add to the weirdness I guess.

5 minutes older than the prior block:

I haven't been bothered to trawl for more.

Is this how you generate the Black Money of The Ancestors?

I'm not even sure what edit of which post to respond to.


Please tell me what part of that statement refers to you?


Also, yeah you're starting to act a little jumpy too. Relax. It's bitcointalk sometimes people just ramble.

I had no intention for my bit of observation to drive you into a frenzy of self defense.

Yeah I'm aware of the , uhhhh, inventor of this.

I don't mine much but I've not seen a blockchain adjust as fast (and as far) as this one.

 I noticed the coin, started a machine, compiled the wallet and before I could even start a 150kh/s miner BCX had the block chain locked up way past what most people like to solo mine.

It might be a good solid coin.  It just lost the original point I think, of being attractive or beneficial to small miners. It needs pools IMO for any stability. And even then it's pretty gamable until there are a few hundred Mh/s consistently mining.

Perhaps a good "community coin", it should be resilient to attack. And the fast adjust means less incentive for the attackers to sustain. But if it was a coinchoose/cryptsy coin the rollercoaster would be ridiculous.

If it can maintain target transaction times he may have stumbled onto a coin that is more attractive to users and less attractive to miners altogether - a push back towards what I perceive to be "the original idea". If a lot of people are willing to mine the chain to support their use of it instead of for direct mining profit it could achieve some stability.

I don't know, just some ramblings not really meant as criticism, and certainly not for you.  It's nice to get a chance to see the thing run.

But it runs a bit like it's designer.  A little jumpy and easy to drive up the difficulty.

So, you missed the push up to 2.88 in <40 blocks?

This thing revs up like a racecar - definitely no gift for "small miners" from what I've seen.

I did download the new client and got my spots, too.
