PXC Mining - Call to action (?)

SixGun

Hi gang,

Just thought I would post this out here as it seems to be that PXC is stuck in the vicious, post low diff raped by jump miners state, cycle of high difficulty/low hash rate. Anyone want to join me in pointing some hashes at their network to get them over the hump? I know FTC is kind of a “little” stuck in this situation too, but we’re coming out of the last cycle. As of this writing the PXC network, according to pool stats on pxc.theblocksfactory.com, to be running at 47 Mh/s…that’s right, [glow=red,2,300]47[/glow]! They have just < 200 blocks to go to get to the diff re-adjust, and I’m concerned about their hash rate vulnerability right now.

Let’s put this partnership to work, as “throwing hashes at a partner network” was one of the benefits I remember seeing before things were finalized. I’ll be moving my hashes back over to pxc (@ the blocksfactory) for a little while. Sorry d2…I’ll be back, I promise! I only have one rig so I’m an “all or nothing” miner right now.

Come on folks…there’s a fire in the neighbors house, let’s put it out!

I’m in, about to adjust my miners right now. The success of one coin, will be the success of all 3. We’ll have a press release out later in the week that will explain that in detail. In the meantime, let’s get some hash moving!

Thanks for moving this over. I wasn’t sure if I put this topic in the right place, but didn’t want to throw it in the mix of the Feathercoin discussion arena.

I appreciate the post, you nailed it.

I’ve been mining it :)

I have a PXC pool too lol, but I don’t really mind what pool people choose to mine on :)

I’ll jump over for a bit.

Thanks D2.

I am mining PXC last few days…

Still there chugging away. It’s a good pool I appreciate you setting it up.

Is it possible to fix this problem for the long run?
Not very fun needing to diligate hashpower because a coin has gotten stuck at way to high diff, due to those pesky “greedy coinhoppers”

I will of course diligate my 10Mhash on to phenixcoin to help them find those blocks.
But its not much fun having to work the diff down and “losing money”, then a couple of days later we’re back at it again
because the coin got lucrative again with lower diff.

I think the 44,4% rule that feathercoin has implementet has worked pretty well so far, at least the diff doesnt get driven up to damn high before they jump ship.
it roles evenly from 68-137, so i can allways just calculate the midlenumber for getting a “longer term” mining estimate.

Once we get past a few announcements, we’ll start sharing resources for long-term success.

I see theres several pools that are multicoin pools. That will mine the most lucrative.

A “multipool” that evenly distributes the hashingpower among the three coins would be great.
With a few fixes here and there it might be possible to add in some 51% attack sensing that would delegate hashing power towards the coin in need.

alternative put in some scripts for the users to modifi the percentage of each coin he would like to work on, example 50%ftc,25% pxc, 25% wdc.
And also with an option where the user can agree for the admin to override in an event of an attack.

Will look in to this as soon as i get some spare time from my normal chorus. (doing complete reconstruction outside my house with the land…)
and yes im also building a dedicated larger room for hosting my rigs :P

EDIT:
Would be great with some inside updates justabitoftime so i may start digging into solutions.

the biggest problem is that the bitcoin formula is base on only one coin. with one coin it’s how many are mining. Multi coin profitability to mine change the picture. now the profitability is a factor and the mining pool switch partly depending on the profitability.

changing the difficulty to be more aware of this reality is possible. But this need a hard fork similar to 33000 FTC one as the diff calculation need to be changed. many solution can be implemented some example are.

fast small change. like 1% every 15 blocks (big change fast lead to very bad retarget so small but not to small to still adapt to the reality in a timely way)
medium with medium change : like feathercoin 41.4% every 504 blocks (still a bit big in retarget, making small yo-yo effect, but mostly controled)
correction ratio: retarget to a ration - 3 last retarget factor. similar to 3 average on graph so the retarget move according to a longer average then the current retarget and be smoother when yoyo effect occur.
way more method are possible, some involving probability and/or price factoring

I was thinking more in the timetarget.
Isnt it possible to somehow have a failsafe when it comes to retarget time?, but this may make the blockchain depend on centralized points? im no expert on this stuff. So sorry if im asking dumb=)

groll

the retarget should use a slow change over time and/or a long sample for bigger change. if not an attacker can use this to boost/lower difficulty. you always have make sure the solution can’t be exploit to put you where you try to not go. time is dictate by the block miner and is only validate between median for last 11 blocks time and now + 2h. so major diff change for short time are easy to exploit as the time can vary greatly. This can’t be corrected without major change in the protocol (all coin use that time validation as far as I know).

In fact the retarget is a time target as it takes [b]formula not exact and simplified to remove some math[/b]: (now - the last retarget time)/ number of block = actual time between block
adjust ratio = target time/ actual time between block (adjust it to be between min/max change)

next diff= current diff * adjust ratio

Call to action! All must help out!

cryptomaker22

“call to action”!

svennand

picked out 21 blocks since last night, so call to action is ongoing from my side ;)

ghostlander

Didn’t count how many blocks I’ve found at D2’s PXC pool yesterday and today, but quite a few. 4 blocks including 1 orphan in 4 hours of low difficulty alone, though the network hash rate was high at that time.
