BTW i think your blocks are not making it onto the network.

I don't know, though P2Pool usually does have a lag time before blocks go through. Not sure if it had anything to do with the 512 blocks.
443  Alternate cryptocurrencies / Altcoin Discussion / Re: Need p2pool for BitBar. Any p2pool gods?? on: May 03, 2013, 03:38:26 AM
281 accepted shares, don't seem to be getting any transactions. I think it's 512 blocks before mature though.

Going to take it off for now and see if payouts go through.

someone slap a pool together

working on it...

Actually, spoke too soon. Looks like it requires code modifications to p2pool (network.py and possibly others). I am a python developer, but have no idea what's necessary here. If there are any p2pool gods, I'd be happy to host a pool, but will need some help making the necessary code modifications.

Yea, I tried that too. I remember that this was the case with PPC too?

In general, if you have to ask, then no.

Having traded for over a decade on the (real) markets though, I will say that the cryptocurrency markets are more similar to the pre-2000 markets during the Internet bubble than today's algo-controlled markets. Much more directional, less (relative) churning, etc. It's a refreshing change of pace from the stock markets of today where robots fight over fractions of a penny and ignore everything else (in fact, "noise" is actually a weapon used by Wall street firms to confuse other firms), in part because exchanges that exist today suck too much for millsecond-trading platforms to possibly function at all.

Here's a nice picture of the crap the modern-day (human) traders have to deal with. Glad I'm no longer daytrading. http://www.metamute.org/editorial/articles/destructive-destruction-ecological-study-high-frequency-trading http://www.zerohedge.com/news/charting-unprecedented-hft-driven-rise-intraday-trading-volatility

Looking good here, lots of great ideas.
451  Alternate cryptocurrencies / Altcoin Discussion / Re: Official Poll for "CureCoin" has been requested by Stanford University on: May 01, 2013, 09:36:23 PM

You really can't do that with something like protein folding simulations (I would know, I've worked in the field for three years...).  In fact, most scientific problems involve calculations applied to stochastic problems where they don't necessarily know what the results will be.  The only way I can think of is to just use a ripple like system where whatever at home gives you credits based upon your solutions being provided to them.  But it's not necessarily a bad answer to this problem, it's better than folding and getting nothing but points on a leaderboard.

If opencoin just released their source code you could directly port it and then use it to make a network like ripple for your coins -- but they haven't.

I've had this idea in my mind for the last few months, but I haven't had the time to get started. I suppose the name CureCoin would generate more interest than my idea of ScienceCoin. The main point though was to release an alt coin that actually serves a purpose.

My idea was to auction out (in BTC) the hashing power of the network, and return on a pps basis to the miners. So essentially ScienceCoin would be a - cheaper than supercomputer option - for anyone requiring distributed computing solutions.  Obviously the hard part would be to figure out how to allocate simulations/problems to the entire network. I suppose something like Hadoop could be used for that?  
 

I'm all for "ScienceCoin" concepts, as long as there's a good POW function. Centralization is good in the case that a party can enforce the use of a certain algorithm, and implement checksums to make sure that the appropriate work has been performed, but is against the grain of most cryptocurrencies current out there.

BTW taco, forgive me if my ignorance is showing. My current field of study has nothing to do with protein folding or structure, and my knowledge is essentially in layman's terms (a scientific layman that is).

Oh, why not:



Font is Gotham Bold.

The "loop" emphasizes the proof of stake system (which is the core innovative feature) - coins make more coins. Haven't matched the correct colors, but that can be tweaked.
454  Alternate cryptocurrencies / Altcoin Discussion / Re: Official Poll for "CureCoin" has been requested by Stanford University on: May 01, 2013, 08:16:47 PM
"for decades" ... that's ambitious. Curious to see what the F@H team comes up with. They should, of course, realize that POW schemes can change over the evolution of the coin (maybe another suggestion for them is for a consensus voting system to be implemented for client/POW alterations, similar to what tacotime is doing with MC2). No need to perfect it during the first iteration.
455  Alternate cryptocurrencies / Altcoin Discussion / Re: Official Poll for "CureCoin" has been requested by Stanford University on: May 01, 2013, 08:07:16 PM
Well, it depends what you define as "verifiability". True, the minimum free energy structure doesn't have a 1:1 correspondence with the actual biological structure (in fact, I agree that free energy in itself is a pretty horrible metric), but similar systems have used energy as a decent ranking metric (google Foldit), and it's "the best we've got" as far as a concrete, verifiable calculation. Furthermore, computation of the free energy is far simpler than other possible metrics, whether homology-based (does this look like an evolutionarily related structure), domain-specific (does this have an appropriate # of helices, sheets, turns), etc. Thus, we can make do with free energy as a check for PoW, and I wager that the expansion of computer power for such a project will outweigh the negatives of not relying on other forms of verification. Researchers then can use these structures to then run further tests (such as domain classification, etc), which they might not be able to do if they're scheduled for indefinite amounts of compute time several months in the future (unless you're in a Nobel winning lab with a big fat NIH grant, it's tough, I've been there).

Of course, the problem is "which energy function". I suspect the F@H team is on that problem.

The bounty system that I proposed in the other thread allows for these other metrics to be slowly incorporated in the evolution of this coin (i.e. accept structures of protein XYZ only if mean C-alpha distances to reference homology structure is less than 2A.) But that will come in a future version.

456  Alternate cryptocurrencies / Altcoin Discussion / Re: BTC MINER uses MASSIVE HASHING POWER to CURE CANCER! on: May 01, 2013, 02:34:05 AM
Do someone know what is the computational power of bitcoin network compared to the current fastest computer http://top500.org/featured/systems/titan-oak-ridge-national-laboratory/?
Of course it must be much higher but what scale? Thanks

Doesn't really translate because bitcoin is not floating point ... but:

That computer: 17.6 pflops
Bitcoin network: 918 pflops (http://bitcoincharts.com/bitcoin/)

In fact, Bitcoin is fasterhas more processing power than all of the computers on that list, combined. Times 5. This is also 100x the computing power of the entire BOINC network. That's the magnitude of computing power we're talking about here. Bitcoin is on track to becoming the first exaflop distributed computer in the world (most likely ahead of NSA).

Basically, imagine protein folding with 1% of that power. That'll make a huge difference.

Prediction: by the time NSA gets their exaflop supercomputer (end of this decade), bitcoin will likely be at 100 exaflops. Conservatively.

Remember that

Quote from: Tom Evslin
Nothing great has been achieved without irrational exuberance

The reason that we have a transcontinental rail system was because of a railroad bubble back in the 19th century. The reason that we have companies like Facebook and Twitter, that we can have telemedicine in India, that bandwidth is so cheap nowadays was because of the Internet bubble. And the reason that infrastructure will be adopted around Bitcoin promoting it to a real currency will be because of the many inevitable bubbles.

And yet people wonder why the tulip market is worth billions today. (We just have much more volume nowadays)
459  Alternate cryptocurrencies / Altcoin Discussion / Re: BTC MINER uses MASSIVE HASHING POWER to CURE CANCER! on: April 30, 2013, 05:47:55 PM
Still, it's very much centralized (at least at the start). I've been proposing a system that transitions into a decentralized scheme as time goes on, but centralization and consensus of what proteins need to be solved will have to be in place at the start.
