Topic: [ANN] Catcoin - Scrypt meow! - page 37. (Read 470739 times)

stop doing drugs mate. Cryptographic Anonymous Transactions coin isn't going to fork because you're smoking a bad batch.

Is there some sort of collective amnesia taking place? You do realise Catcoin nearly died at the last fork, right?

This is such a bad idea. Let the network decide. If you start talking to the exchanges, they're just going to delist it and be done with it.

Can someone please contact cryptsy and tell them to increase confirmations to a minimum of 12, and maybe up to 40 until there is a new consensus released code that results in an overnight/high difficulty period hash rate of at least 200 Mhash?

The FTC attacker would love to remain anonymous, and might have already been probing CAT to do exactly the same thing.

Now this is only my personal opinion, but I think we have two effective defenses:

1) lots more hash that sticks around
2) transparency (i.e., get people to publish 'well-known' generation addresses)

I also appreciate that some of you might want to remain anonymous, and I'd have to advise you to use **OTHER** cryptocurrencies if anonymous transactions are important for you. CAT is currently not big enough to pay the costs (in hash rate) needed to defend BOTH the integrity of the block chain, and your privacy. One of them will have to give.

Wait, which one is which?



Top two are votes for the fork and the bottom two are against? I'm a little confused.

Skillface, please mine on one of the p2pools, and post your address as a 'no-fork' vote. As far as I can tell, most miners with over a megahash are coinhoppers because they need to pay their electric bills. I take any hash, no matter how small, that STICKS AROUND DURING HIGH DIFF a hell of a lot more seriously as a vote by hash than the guys who only show up to grab some coin and leave. You can make your choice transparent to the rest of us by mining on a p2pool node (like http://p2pool.name:9333/static/ )

The difficulty changes in 4 blocks, (block 20984) and if, because I threatened to fork, the coinhoppers stay away, YOU might actually benefit. If we have reasonable behavior of hashes, and the next low-difficulty period takes more than a few hours, I have plenty of time to pull the fork at block 20999. If everyone shows up to make a profit and screw the little guys over, then I'm going to make it a little more expensive for them, at least this time.

Hell, I didn't even stick around for a couple of the high diff periods, I just could not justify it, and it pissed me off I had to make that decision to protect my own interest at the expense of the community, and I decided about the only ethical course of action I could take was do a live test.

Since I mentioned the need for a testnet and dedicated hashing power, what if we made a 'catcoin-test' pool who's primary purpose was to run on the catcoin testnet, and when we are NOT testing, run as a profit-switching auto-buy pool that pays out in CAT. Then we'd really know the best way to deal with coinhoppers because we ARE one.

I have to say I'm pleasantly surprised with the research that's being put into this. Some smart people in this thread for sure.

Look people i have some simple research on diff recalc

does version 0.8.6.1 not syncronize anymore?

Get me a genesis block for -testnet and a model that ALSO includes coin-jumper profitability calculations, and I'll back test it.

Can you please confirm the output of the mainline released catcoind, when run with 'catcoind --testnet' exits immediately on startup and paste the output?

You are running a coin with no test network, and no models to backtest with, and you still want backtesting?

It's clear to mean something is broke, and the only way to test it is run it live, unless the community is going to step up and provide a testnet with 10 Megahash we can turn on and off at will.

Well it's not like it's going to get the hashrate it needs to take effect anyway, so I guess the entire discussion is moot. Right now I'm more concerned that this may have an impact on any 'official' fork in the future.

I'm not sure what part of this you're not understanding. This isn't our fork, the board or KR105 didn't authorize this, nor did we get a consensus from the community on it. Why? Because we didn't have anything to do with it. These are the actions of 1 community member providing an alternative. I can't tell him to take the code down, because I have no authority to. You could do this with any coin, clone the git repo and call it a fork. THe only way it actually becomes a fork is if people largely adopt it.

I've spoken with hozer about his weekly updates being a bad idea, but in this case he seems to want to do his own thing. He is providing assistance to Catcoins board, but these actions with the alternate fork are his and his alone. I have messaged KR105 to see if he will do another fork for us and we really need to get that done. Please people, don't let the actions of one person out to be more than it is. Stop focusing on this and focus on fixing this coin.

So dogmaportraits.com already supports CAT according to the CoinPayments Directory. Hopefully other sites on that list will add it as a supported payment type soon.

Good news for Catcoin. I think this coin is going to take some time to take off. I am currently mining other altcoins, and I hope they pay off. A 3rd of what I make will be invested back into Catcoin. I'll let everyone know exactly what my stake is in Catcoin.

I still have faith in this coin, but I need more BTC to be able to support it. When I invested I put 0.4 BTC into Catcoin. I need to buy back in for at least a couple of BTC.

Quoting this for the good initiative
If you have many steam keys I would like to suggest you to make a website would be more interessting


great news hopefully we will join more services

.. what?

That's a great news.

We actually got in by a hair. Good news.

I bet LOT voters would be absolutely pissed right about now

Hi Nullu,

Thank you for your thoughtful contributions to this discussion.

I think it's impossible to directly factor in market price, and clearly if this graph is a fair representation of the "set difficulty based on the last 36" method, there are plenty of opportunities for the miner-dumpers to show up and keep the pumping and dumping of difficulty going (perhaps with even more extreme difficulty swings).

I do believe, though, you can generalize about what people would do when the market price has gone up, and distinguish it from the case of temporary spikes due to previous low difficulty - namely, put the miners through a test of endurance. If the difficulty climbs up in response to hashes going up, then a bunch of hashers disappear, and so the difficulty drops way down (as it should), a test of endurance would be to at that point constrain the difficulty from climbing very fast (say maximum of 1.25x per 36-block retarget) and simultaneously constrain the rewards to a fraction of the normal amount such that the coins-per-hash remains at the same level as the high difficulty era that preceded it. If the market price really had gone up a lot, then people would show up in large numbers and hash notwithstanding these constraints, until difficulty and hash levels recover to pre-crash levels. And at that point, the constraints can be removed, and we would be on solid footing. If the new people who show up find they are not making enough profits due to the low reward plus low difficulty (same ratio as normal reward high difficulty), they would leave after a short time, and the difficulty would remain at the low but realistic and sustainable level, until prices can go up and thereby attract people to mine long-term due to merits of the value of the coin moving forward rather than due to very short-term "profitability."

Which is the factor that is hardest to predict. How do you factor in market price when it's inherently unpredictable?

I just now set up an account and funded it with 100 Cats tried to fund it with 100 CATs, but the site says only BTC deposits are available now. I am happy to support any site that adds Catcoin support, so help me transfer the CATs in. Thank you for that.
