[ANN][GRS] Groestlcoin | 1st to activate Segwit & Taproot

[child_harold]

x3 hashrate for 2x power.

It's gonna mean NVIDIA cards prob compete with / outperform AMD for a while…

… I fully expect AMD optimizations to follow when other devs trying to mimic cbuchner's technical brilliance on AMD.

This NVIDIA development will just raise the standard for Devs working on and optimizing mining software. One of the reasons I'm into Groestlcoin is because the algo better suits these sorts of developments than any other imo. This is the sort of news I want for Groestlcoin. AT  the cutting edge of mining!

It'll be interesting to see the market reaction bit I dont see any doom + gloom here.
Just some healthy disruption to the staus quo. I think we're all into that here!

yes but if the algo takes more power, it will be just like all the others non-scrypt coins like those based on keccak, for example.
so not special :-)

not true
groestl main advantage isnt power saving
part of powersaving will be lost with optimized mining isoftware

groestl isnt a mixup of as many algos as possible which create more security riscs and performamce troubles than a single algo
we will see x11 x13 xy99 algos poping out like mushrooms

groestl isnt a cryptocoin construkt its a serious cryptografic algo for multi purpose
beeing able to utilized in many hardware/ software enviroments

fast hashrate to secure network without security riscs and a few more months broad coin distribution without asic owner get all the diamonds was our reason to choose groestl

ok but what's the difference with keccak?
"fast hashrate" doesn't mean much: distributed hashrate is what counts.

Well one of the differences between Keecak and Grøstl is that Keecak was developed by a multi-billion dollar company registered on NASDAQ with friends and parties with vested interests throughout the industry. The results of the SHA-3 competition are therefor of little relevance to me.

Grøstl was developed by Academics and science professors in Denmark and Austria who created an algo very different from those of the SHA family.

I know which I trust more.

… I fully expect AMD optimizations to follow when other devs trying to mimic cbuchner's technical brilliance on AMD.

Let me remind everybody that ccminer is a collaborative project - and in this case my co author Christian H. did the research into alternative Groestl impementations. It was mostly him who studied papers relevant to bitsliced AES implementations, he got familiar with arithmetics in galois fields and provided a first prototype of bitsliced groestl. We then jointly debugged and optimized the code, also using some nVidia specific hardware instructions (such as the PRMT instruction and the funnel shifter where applicable).

[child_harold]

According to Christian (I hope you don't mind my quoting you)
Dev - pls add my 5000GRS 25,000 GRS bounty to ARM bounty

Will somebody give it a go?

seems that ARM sourcecode for NEON (Cortex A8) is readily available from the posted web sites.

One only needs to integrate it into a cpuminer.

Christian

3) maybe on 64 bit ARM platforms with 4 and more cores, using wide 128 bit SIMD operations (NEON?). I am not very familiar with ARM, so I can only speculate. In fact, our alternative approach would also apply here (and to Intel SSE2/AVX2)

ARM NEON implementations of Grøstl:

We need somebody to try mining on ARM!

so is there a bounty for optimized amd miner? which is the minimum hashrate gain acceptable?

[cryptonit]

u asking twice allready u have a optimized miner and dont wana share without bounty?

The bounty will be a fraction of what you will be able to mine in a couple days with an optimized miner, so no real interest in it.
I was just wondering because nobody answered the question and everybody is interested in an ARM version instead, which doesn't make too much sense IMHO.
The reason is that most arm devices (phones, tablets...) are not designed to run cpu intensive tasks for long (not hardware-wise: they will overheat and throttle; nor software-wise: the OS might kill the process).
It is a good concept for hashrate distribution, though.

While I mostly mine AMD, I think that CPU optimizations should be a major focus, especially with faster GPU hashrates on the way. I think having around a 5-10x gpu vs cpu speed advantage is a really cool feature of this coin and could help with it's success because anybody can mine it.

[fenghush]

You could implement a dev fee in your miner and get a lot more coins than you could have mined yourself. If your miner is much faster than sg-miner then I'm sure you could get away with even 10% fee, something you might want to think about.

Dont have much time now - will flesh it out later…
srcxxx (amongst others) has recently mentioned PoS and maybe switching after a few months. So…

Idea

1.keep mining PoW for couple more months / summer end
2. then move to PoW/PoS combo
3. Move to combo would coincide with a possible rebranding / new logo / PR blitz

Bounties.

This has to be sorted out. I dont officially represent the coin but those of you who know me know Im passionate and dedicated to it.

so in addition to any official bounties I pledge the following

5k for a new logo (to be deemed by consensus better than the existing one)*
10k for 33% or more performance boost to CPU miner (64 or 32 bit)
20k for 50% or more performance boost to AMD miner
25k for ARM miner (code to be made available. payment after verification)

* I like the idea of using the Ø symbol in it.

Others are welcome to pledge themselves (I will track the pledges) and if this is acceptable people's words will count till such time as the Bounties are formalized. Anyway my word is good and I've have paid all Bounties I have offered in the past. Ask instacash for example.

Blue skies and helicopter thinking…

the ARM miner you can consider my personal project but i believe in it. Without getting into a long spiel I would simply point out that Googlecoin would run on ARM. ARM procs are getting a lot faster a lot quicker.
http://mashable.com/2013/12/13/google-intel-arm/

If this coin went PoW/PoS I love the idea of ARM chips helping to secure the network in years to come. In no time the public will only carry ARM. The landscape of mining will be very different in no time at all. The ARM implementations exist and it should be doable
https://bitcointalk.org/index.php?topic=525926.msg6238355#msg6238355

The similarity to AES might also mean Grøstl gets hw accelaerations.

Any feedback?

5k for a new logo (to be deemed by consensus "cooler" than the existing one)*

Why would you change the logo? In my opinion your current logo really stands out from a wall of round coin logo's and it is something most people know. Recognition is always good in something as a logo.

[fenghush]

I advise against hardforking unless something is broken. Features like PoS are mostly untested and prone to abuse/exploitation.
If it's not broken, don't 'fix' it.

Good to hear! Just wanted to see what people came up with

Again glad to hear that. Thanks for the feedback

pos untested?
since peercoin pos is tested......

but true is that pos add difficulty in maintainance and update code

u cant launch a pos coin without maintain code
