How do we interpret that the trend of the number of wallets created broke at about the same time as the huge increase in network size?
December 01, 2014, 03:19:58 PM
memory options which exist but maybe this is a nice option for future developments to plot large farms. one fpga may create about 100 mb plots per second.
Interesting, especially wrt what burstdev said earlier, to get accurate ballparks of what is possible to do in hardware. Shabal is 40 rounds of 1536 bits state, and the plot algo needs 256kbyte. I presume you'll see fairly scrypt-ish behaviour there, adjusted by more complexity of shabal vs salsa20.

okae your welcome.... 
TY bobafett
you are welcome!!
but i hope you increase your TB soon to get some burst!!!
but i hope you increase your TB soon to get some burst!!!
TY rollingMyCar, i hope that too, thats my plan to continue increasing it, but you know the money is the problem so i will do it but slowly
You are welcome to community!Well...2TB will be enough to test POC mining at the moment.With current diff you will get about 1000-2000 burst/day and you can forget about solo mining.I have found 0 blocks solo in 5 days with 16 TB.If you need some help,you can PM me any time.
TY Trollollo, i dont want to bother you with questions, but if i really need help i will considered it, ty again for all!!

Dear All,
I've been downloading all the stuff to mine, but when I try to join (any) pool it tells me that I cannot change the reward recipient. I tried to receive some burst via a faucet, but even then the faucet gives some error. (I've set-up solo mining, but I keep on getting "Error reading file: ACCOUNTID_1_8..._8191", where 1, 8.., 8191 are the parameters I've set for the miner.
Any of you had the same problem? I've been following the guide for linux in this very topic, the wallet works, the plotting is stuck on this line:"generating from nonce: 1, writing from nonce1; generating from nonce 8192;".
I've set up about 8M plots, that should be about 2Tb, maybe I must finish for this process to end before mining? Maybe the starting plot (parameter which I set to 1) should be some actual filename not just an id number?
Is there anything else I should do to activate the wallet? At least to receive the faucet burst for testing it out?
Thanks for your assistance!

looks like the last diff increase pushed the trade volumes on the exchanges towards zero.
is this a good or a bad sign?
is this a good or a bad sign?
I dont see anything out of ordinary volume wise, maybe even slight more volume (used to be 2BTC avg volume, now its around 3, across all 3 exchanges). The top volume moved from polo to cex recently, though.
today i finished my tests with a arm based standalone miner.
plots are parsed at 8mb/s (mainly limited by the cpu) which is enough to run a 6tb sata drive with it.
i used one of these 50$ boards and a 6tb wd red hdd.

it has been a bit tricky to power this with a regular power supply but there is no magic involved.
once the device is booted up the sd card is not needed anymore cause everything runs from ram.
to fill the drive up with plots i attached it to a regular pc. the wallet still runs on a regular pc cause i mine solo.
during the next couple of days i expect to have tested the average power consumption for this setup in production.
so far the setup seems to require less than 6 watts on average.
if anyone is interested in putting a ready to mine image together and maintain it (eg. someone with a pool) pm me for details.

Neat!
I'm of the opinion raspis are far too expensive to cover ROI but to each of their own.
What about consumer hardware with other purpose already (wireless routers with USB2 ports in particular). Some are fairly "powerful", almost as a raspi, ie this is what I have:
http://wiki.openwrt.org/toh/tp-link/tl-wdr4300
Shabal probably sucks roughly the same there as well.
the shabal source for mips (http://www.shabal.com/?p=213#more-213) exists and needs only be replaced in dccts miner with the mips version.
i used ddwrt on tplinks in the past by my own for vpn setups and know that they are not the fastest.
simplest thing would be to replace the shabal.s file and crosscompile it for the platform for a test.
in general i would say using embedded router on top of routing for mining only makes sense for faster models which have enough cpu power.
the nice thing with the banana pi is that it provides a sata port which also supports port multipliers (really slow).
adding a usb disk to a ddwrt tplink router may be much simpler and even cheaper if it works.
what i may look into soon is a fpga shabal implementation. on a virtex-5 a throughput of 2gbit should be possible. i have not looked onto the memory options which exist but maybe this is a nice option for future developments to plot large farms. one fpga may create about 100 mb plots per second.

This coin call my attention, im reading how this work and from my point of view the dev is doing a great job.
PoC is just a new idea and i start to love it
, i just buy 2tb external hdd to start mining it, do you think is enought for a good start?
i will try to use this miner -> https://bitcointalksearch.org/topic/m.9696842
with the poolV2 config, i will post the results as soon as my new hdd come
I will keep and eye on this thread and come back more often!!

hi blago!!!
any idea about this error???
....
i get the error above!
it's just artifact in fast blocks, miner sending share whith deadline=0 and ID=0. i'm try to correct it's in the future... do not pay attention.
ok thank you!!!
i continue to use!!!
thank you again!!!!

PoC is just a new idea and i start to love it, i just buy 2tb external hdd to start mining it, do you think is enought for a good start?
i will try to use this miner -> https://bitcointalksearch.org/topic/m.9696842
with the poolV2 config, i will post the results as soon as my new hdd come

if only the memory bandwidth would be the limit.
But its not. You can't just ignore the biggest part of the equation.
i think of some sort of nonce to deadline code comparable to what the wallet does while verifying.
Of cause thats what you are doing. Generate the whole nonce, take the scoop you need and check it for the deadline.

What if someone did gpu miner? One part of miner write in RAM file, other part read, then RAM clear and again in a circle? Its possible?
nothing change...
someone has tried some hundred pages ago...
but without any results
Its possible, but not worthwhile. A high end 200W-GPU equals about 40GB of disk space. Plus your amount of ram of cause.
i do not know if the eqution 200W-GPU = 40GB is right.. but if ita so... it is a waste of time and energy..
or maybe did you want to tell 40TB??
This was the result I got with a modified GPU plotter on a R280X. Maybe it can be tuned a little more, but certainly not to 40TB.

What if someone did gpu miner? One part of miner write in RAM file, other part read, then RAM clear and again in a circle? Its possible?
nothing change...
someone has tried some hundred pages ago...
but without any results
Its possible, but not worthwhile. A high end 200W-GPU equals about 40GB of disk space. Plus your amount of ram of cause.
i do not know if the eqution 200W-GPU = 40GB is right.. but if ita so... it is a waste of time and energy..
or maybe did you want to tell 40TB??
This was the result I got with a modified GPU plotter on a R280X. Maybe it can be tuned a little more, but certainly not to 40TB.
a highly optimized code may get close to 12 TB in 240 seconds if only the memory bandwidth would be the limit.
i think of some sort of nonce to deadline code comparable to what the wallet does while verifying.
either way you compare 250 watts against 14 watts which makes it impossible to mine with gpu.
