Where is the miner in Windows?

one e3 1230 one day can mining 72coins .this coin. start pool mining after one 8 thread cpu only 0.5h ,all people also think mining this coin ah ?

Here's the original Pebble miner, hashing at 0.71H/s and using 13GiB of RAM (NSFW): https://ottrbutt.com/miner/pebbleminer-stock.png

And after about 30min of modifying the code, 4.1H/s, and using 416.8MiB (NSFW): https://ottrbutt.com/miner/pebbleminer-wolf-01222015.png

Thanks to Wolf0 for publicizing the flaw in the algorithm instead of privately exploiting it!  There is a flaw in the algorithm where the miner can store every nth value in the state, instead of every value.  This reduces the memory usage and it ends up being faster to recompute the values than looking them up in memory.

I've updated the algorithm and am currently testing it.  I'll release new source and binaries on Monday or Tuesday and there will be a forking change a day or two after that.

please give windows minerd try all people can mining ,thanks for you

He'll probably release the minerd before he hard forks, so it can be run on testnet to confirm it works.

@XPB, if you did a hard fork, what about the coins which we have mined? Will them became invalid?

Unless something goes terribly wrong, the hardfork should kick in smoothly at a pre-determined block number, after which blocks on the old algorithm are rejected by peers running the up-to-date software. This would not have any affect on current balances if done properly.

So much for a fair initial distribution.

Who could possibly predicted this?

Why not start with a testnet until public CPU/GPU miners are optimized and block explorer/wallet/pool are ready?

Otherwise Claymore will pwn us all with a private miner for his quad FirePro W9100 box.   

Sorry Wolf0, no offense intended!

lol 23 days before wolf0 looked at this and made an optimized miner and decided to tell the dev so pebblecoindev can level the playing field by fixing the issue asap. this is not sounding like a story about unfair initial distribution. unfair would be if wolf0 mined this for 20+ days then told us about it.

The low prices being offered indicate those coins were not mined on expensive 13GB+ machines using the public software.

wolf0 isn't the only one who can un-deoptimize a purposely bloated/crippled algorithm.  We've seen this movie before, and sequels almost always suck.

or theres like 10 miners on the coin and low interest at this point and running a cpu costs pennies so its selling for cheap if at all.

Running a cpu may cost pennies but powerful 13GB+ systems could be mining many other coins, so there is an opportunity cost.

OTOH, if you have an unfair advantage from a private un-deoptimized miner (and credulous buyers standing by), it's pure profit.

Read my edit to my post above - just because you're not good at making fast code does not make it de-optimized.

OK so it took a mere 30 min to (un-de)optimize, only because you are 1337.

Then it might take a day or a week for a lamer or team of lamers.

I still think the coins being dumped for sale seem too cheap to be fairly mined.

Since a fair launch and democratic mining were XPB's raisons d'être, I find the (albeit relative) ease of (un-de)optimization a matter for concern.

Why not use a testnet until optimizations and GPU ports are public to avoid FUD and hardforks?

Eh, I sold 4800 XPB for 0.144 BTC earlier, and they were mined using the stock miner on EC2, turned a small profit.

I want to buy some XPB, PM me with your ask if someone wants to sell.

EC2 with 13GB RAM?  That seems expensive, but OK fair enough.  I guess difficulty is very low.  

What's the total emission, so we can put the sale quantities in perspective?

[loveyouforever]

Getting "Transaction creation failed"...

Maybe you can split your transaction to 500 XPB each, I made a deal with another guy, it works.

[poisenrang]

howmuch is 1 coin worth?

[ikiscream]

Exchanger launch ?

Simple. No one will release really good optimizations. They will wait. Sure, you'll catch the small shit like this, but you won't get really good work unless you pay for it.

This makes releasing a coin have a cost - the dev not only has to make the coin, but must invest real money into it; you won't see many doing this. If it did happen, I would be quite pleased - I could get paid, and help a coin that the dev has shown they are truly committed to.

I have around 2000 XPB to sell, spent around $20 to mine them.

Wolf0 when you partner with a coin dev, or become a coin dev, please let me know =)
Maybe a coin with Proof of Optimization.
It amazes me how PoW, works, and how optimizations from CPU, to GPU, FPGA, to ASIC and the miner software itself can transform. 
Or maybe a paid school teaching how to make better mining programs?

So far, there are about 885,000 coins on the network, I believe. At current prices, that puts the marketcap somewhere between $5000 and $7000, growing somewhere around 90 cents per minute, or $54/hour.

Also can sell another 4,400 to anyone interested for 0.11 BTC.

what time update new minerd ? dev

[Jocuserious]

You pretty much have to be a miner to interact with this coin right now, right?

Pretty much - but since it's a CPU coin, it's not like it's hard to be a miner.

Computer died beyond return.  I'm currently on a laptop from 2007.  Temporary problem but relevant for the question and time frame.

Thanks for the reply.  I might entertain some of the offers above.
