Going with Cryptonight Monero AuxPoW would just be handing all the newly hashed coins over to botnet 'owners'.  
Could you describe what the problem with botnets is? I am admitedly ignorant here, but from what I understand, this is not a big deal.

If you look at Monero pools you'll see lots of miners with hashrates equivalent to 20,000 CPU cores and more and it wouldn't be profitable for people to buy or rent that many CPU cores.  So they're very likely using stolen processor cycles from infected computers that are controlled within a botnet.  Some large botnets can control the resources of up to a million infected computers without the legal owners of those computers even knowing.  These botnets get to use the spare CPU cycles and memory of the infected computers.  So adopting the cryptonight hashing algo would mean handing over the overwhelming majority of all newly hashed coins to a few small groups of criminals.  Going with a GPU biased hashing algo would give dedicated miners an advantage over the criminal owners of botnets.  Although if Anoncoin or the coins it merge-mines with within a myriad become very valuable.  Then botnets will still target GPU biased coins just that GPU miners will have an upper hand.  As even Bitcoin was still plagued by botnets in its GPU days at times.  The only way to truly avoid the botnet problem is to use ASIC's.  The only thing is though is that GPU's are more readily available to anyone who wishes to contribute to the network.  A lot of people and especially the cryptocoin types will already have GPU's that they can use to hash with.  While someone new to the game would find it a lot easier to buy or build a PC with a GPU fitted.  
PoW is supposed to be about fairly sharing the hashed coins to miners who help secure the network.  While the more individual miners a chain has then the more people who have a stake in that coins future.  So therefore more fanboys to help evangelise the benefits of the coins.  I'd suppose going ASIC would be fairer than going CPU only well at least it's stop criminals controlling the majority of the supply of all new coins.

This attack shows how using a myriad of AuXPoW chains could avoid this problem.  As by using a myriad of chains then the attacker would need to attack more than one chain.  While using AuxPoW with the biggest coin on each chain would greatly increase the network hashrate.  I think you should quickly adopt AuxPoW with litecoin how Dogecoin has just done so to help stop any potential future attacks.  Then the myriad with NeoScrypt Feathercoin merge-mining and Lyra2 Vertcoin merged-mining can brought in a later date.  Plus it may be worth including Cryptonight Monero AuxPoW with the myriad.  Plus possibly X11 Darkcoin merge-mining included in the Myriad.  To have a total of three to up to possibly five myriad chains all in AuxPoW with the biggest networked coin on each chain.  As with a myriad of five chains then an attacker would need to control three of the five AuxPoW chains to control the network.
Not being a miner, I am leaning towards Crytponight as my favorite proof-of-work algorithm. It is heavily CPU oriented, which will put off mining centralization for some time.

Perhaps there are similar cpu-oriented algorithms out there, but cryptonight addresses another important point: If we go toward merged mining in the future, which coin would we want to do this with? The only coin that I know of that is putting privacy first, and for which the developers have some integrity, is Monero. Given the new partnership between the two developers in PrivacySolutions.no, if we went in this direction, this choice seems to be a no brainer.

The only other algorithm out there I have some respect for is Peercoin's proof-of-stake (though I would prefer a 100% proof-of-stake system...). A built in inflation of ~1% is something that we could probably live with. No one would get rich mining via POS, which is fine by me. Unfortunately, I don't think that POS will work once Zerocoin is implemented. POS would probably only work with ANC balances (which can be "staked"), and not with zerocoins that are in an anonymous escrow pool. I suspect that about a third of ANC will be locked up in zerocoins, which will limit the number of people mining via POS. It is possible that I am wrong, and that zerocoins could be staked like ANC, but this would probably require some important modifications to the original algorithm, and with zerocoin development going on, combined with the arrival of scrypt asics, I don't think that we will have the time to implement this.

Going with Cryptonight Monero AuxPoW would just be handing all the newly hashed coins over to botnet 'owners'.  Having a GPU friendly hashing algorithm helps to keep the botnets away to a larger extent.  Vertcoin is planning on changing to the Lyra2 hashing algorithm.  Which will be GPU friendly plus the Vertcoin core dev team are committed to do what it takes to avoid ASIC centralisation.  Also there's soon to be Feathercoin's new NeoScrypt algo which should also be GPU friendly.  Then there's Darkcoin's X11 hashing algo which is GPU biased as well.  There's three GPU friendly hashing algorithms.  Scrypt merged-mining with Litecoin would be the quickest and easiest solution for now to secure the network.  While the myriad could be added in later.

Peercoin is interesting in that it promotes the running of full nodes through staking.  Which in turn helps to avoid the dangers of the likes of Sybil attacks.  Although as stated Peercoin is of course inflationary in nature with no hard cap on the total amount of coins to be issued.

Does anyone have an opinion on a 100% proof-of-stake system, similar to Peercoin? (actually, they use a mixed POW and POS system.)

The benefit is that there is little energy used with POS compared to energy hungry POW algorithms.

The downside is that there is built in monetary inflation (albeit, very low at 1% for peercoin, if I remember correctly).

People are more attracted to 100% proof of stake in new coins now. Only miners don't like it. For the coin and the value of the coin 100% proof of stake is better than regular mining.

regular mined coins / btc, ltc etc / 1 star

proof of stake / nxt, cap, etc / 2 stars

innovative productive / xpm, ric etc / 3 stars

innovative productive variation of proof of stake / huc, etc / 4 stars

Going to 100% regular proof of stake is like adding a piece of celery to a bowl of rice.
Is it an improvement? Yes.
a significant improvement? No.
Nothing creative or new about it but yes, rice with celery is better than rice without celery.

With a block reward of 2.5 ANC in some months, we will loose all small miners against big centralized miners that will control the network as they want.

Then, in my opinion, PoS would be a good option. They could program the inflation rate to have same coins distribution as the actual PoW algo (4 million ANC at the same approximated date).

Well if the volume and value of rewards are dropping faster than any increases in ANC price.  Then that's where AuxPoW comes into play by merge-mining with much larger networked coins.  PoS in it's current form doesn't really work.  DPoS is interesting but isn't the ultimate solution to replace PoW as a fair distribution model.  A myriad of AuxPoW with much larger networked coins will secure the ANC network a lot more than going to any pure PoS model or even DPoS.  Peercoin is a very interesting attempt at the problem of avoiding sybil attacks.  Although to copy their moves would mean to adopt a continuously inflationary model.  I feel small coins grouping together into AuxPoW could help them build strong networks cheaply.  While using a myriad of merge-mined netowrks could strengthen Anoncoin even more.

I think it'd be good if you made the offline version of Armory to work with Lubuntu.  As most people use older hardware for offline machines plus the latest Lubuntu 14.04 is an LTS version.  I had no luck trying to install the offline bundle on Lubuntu 14.04LTS or Lubuntu 12.04. Going to try with the recommended Ubuntu 12.04.3.

Although I have to disagree cryptonight is CPU only, Claymore GPU miner for instance give 474 H/s for an R9 280x (50% efficiency)... although ofc it is not the huge improvement that other algo sees and its only double from a good CPU.

I agree with the cryptonight algo for CPU one Smiley

my 2c

Say your opinion!

A hypothetical question that does not necessarily have any ulterior motive; If Anoncoin switched hashing algorithm, what type of hashing algorithm would you liked to see then?




An Atom C2750 can get 53H/s on four out of eight threads on 20W TDP processor.  If the CPU's L2 cache could be doubled then it'd probably get ~100H/s at < 30W TDP.

Just to explore the hypothetical, what would be the reason for switching the hashing algorithm?

As they use Scrypt and their network hashrate is relatively dangerously low.  Dogecoin whose network hashrate was relatively massive compared to Anoncoin has already decided to use AuxPoW (merge-mine) with Litecoin to combat that same problem.  Unless Anoncoin changes its hashing algorithm quickly.  Then a lone single Scrypt ASIC miner could easily pull off a 51% attack on Anoncoin just for LoLZ or even destroy the coin completely.  I suppose the easiest option would be to copy Dogecoin's move and AuxPoW with Litecoin.  Although that then opens up the dilemma of ASIC centralisation, but it would probably strengthen the Anoncoin network the most out of any option.  AuxPoW with Myriadcoin is my favorite option.  Followed by AuxPoW with Vertcoin as they're committed to stopping their coin to succumb to ASIC's.

Not quite sure... I'd say CPU only BUT ... in the end the hashing Algo won't change much, right? Mostly the price would be influenced by this.
If we would be able to mine more ANC with cheaper gadgets ... or more ANC with more expensive ones, the price will fluctuate in the beginning.

 Huh why not let ANC stay the way it is? but well yeah, I prefer CPU ... simply cuz I got a bad GPU

The only CPU hashing algorithm that is truly CPU biased (at the moment) is the Cryptonight algorithm that Monero uses.  Being so CPU biased does leave it open to most of the hashed coins going to botnets.  Going to Cryptonight and usuing AuxPoW with Monero is a good option in my opinion as Anoncoin and Monero have already partnered up on the I2p work - https://en.bitcoin.it/wiki/CryptoNight - with the latest smartphones getting 64bit ARM processors then it may eventually become possible for anyone with a smartphone to earn some ANC (while charging) and earn a stake in the network easily.  Although the more CPU biased a coin is then the more profitable it is for botnets to hash.
Other good options include the new NeoScrypt that Feathercoin is looking at.  Which seems like it will be GPU biased eventually which should help keep the botnets a bit further away from owning all the hashed coins - www.feathercoin.com/neo-scrypt-press-release.pdf - Or the Lyra2 algo that Vertcoin is moving too looks like it should be GPU biased - https://vertcoin.org/pow-algorithm-upgrade-lyra2
My favorite option though is a myriad of those three algo's and possible more while also utilizing AuxPoW with the respective coins.  As the AuxPoW will greatly increase the hashrate of each chain therefore making it a lot more secure from attack.  Also using a myriad scheme then an attacker would need to control more than one chain.  If that idea entails more work than the devs have time for.  Then my next favorite option would be AuxPoW with Myriadcoin itself.  Then my next favorite option is AuxPoW with either Vertcoin, Feathercoin or Monero and in that order of preference.  As the Vertcoin devs has stated they will always do whatever is possible to avoid ASIC centralisation.  While Monero with Cryptonight opens up the doors to botnets although does have advantages too that anyone with a CPU can hash it.
All the options I suggest avoid the centralisation of ASIC's (for now).  While if you was to use a myriad scheme plus AuxPoW with each respective coin then the network would become very secure from attack.

Bitminter recently had a block of 99.33% CDF and then 99.25% CDF right after and then two blocks above 86% CDF right after that.  There's a large difficulty change today too.  Is this pool moving to a P2Pool back end right after this block?
Work is underway on doing a p2pool backend. Unfortunately it's a fair bit of work and is unlikely to be working for the next block. It doesn't matter though as once it's working I'll switch it mid-block if I can. It is what's consuming all my pool development time at the moment though.

I'm not sure why people would mine on a p2pool based pool when they could just run p2pool themselves but at least it wouldn't matter too much if people dropped out since the p2pool network as a whole would enable blocks to be found faster vs a lone pool.

The main reason people would want to mine at your pool instead of straight on P2Pool.  Is massively reduced variance on merged-mining.  Otherwise they would have to solo merge-mine the alt-chains.  Which unless you have about 30Thps is pointless.

Yeah I agree Myriadcoin multi-PoW may be a good idea.  The coin can't stay on Scrypt any longer unless it goes to AuxPoW with Litecoin like Dogecoin is currently doing.  While Dogecoin currently has a much bigger hashrate than Aononcoin and they're doing something about it.  To just leave things as they are is only opening up the doors for attacks on the network and the resulting disaster.  My favorite option would be AuxPoW with Feathercoin on its new GPU algo or possibly the Myriadcoin multi-PoW idea.
235  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Official Anoncoin chat thread (including history) on: August 16, 2014, 09:16:49 PM
What is happening about the hashing algorithm?  Dogecoin which has a much higher hashrate than Anoncoin is moving to AuxPoW with Litecoin to help strengthen their network and avoid an attack on their network.  If the community doesn't want to merge-mine with Litecoin have you thought about switching to a new hashing algorithm?  Like either the new one Vertcoin or Feathercoin is choosing.  There's a lot of Scrypt ASIC's out there now and one biggish miner could easily pull off a 51% attack on Anoncoin for LoLz.  I'd personally prefer the coin to AuxPoW with Feathercoin so that I could fire my 280X OC up  Grin
236  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Official Anoncoin chat thread (including history) on: August 15, 2014, 11:57:03 PM
A lot of people don't trust or respect the Anon branding.  My personal view is indifferent but I do admire some of their work.  Although there is a lot of uneducated and ignorant people waving that mask around even if it is with the best intentions.  Using official Anon branding may backfire, but it could also pay off if you get a lot of their hardcore supporters onboard with this project.  I've mentioned Anoncoin to a few of my hardcore crypto friends for a good while now and some of them are really put off by the fact that Anoncoin uses the official Anon branding.

Huntercoin and Fusion coin can be hashed AuxPow on SHA256 now I'm lead to believe.  This pool really needs to use P2Pool as a backend or it's going to die very soon.  I've seen blocks on other pools take over 98% CDF.  So we could be here for a few more weeks yet with this block.

Edit:  Maybe you could work with Minergate only having the binaries for so long.  So that you could both see a return from its development before fully opensourcing it for the community.

I think you should offer a percentage of each hashed coins fees to each coins core devteam.  Or at least to bounties for project developments for each coin respectively paid from each coins fees to each coins new development bounties.  Like a lot of the leading pools hashing Monero already do - https://bitcointalk.org/index.php?topic=583449.0 - It would show that you're concerned a lot more with each coins development.  Rather than just trying to get rich quick.

Edit:  Maybe showing some support for the opensource ATI cryptonight miner would be good - https://bitcointalk.org/index.php?topic=671784.0 - As you'd obviously gain a lot more fees from its implementation.
