Modified difficulty graphs to NOT show PoS difficulty, as it is orders of magnitude lower than PoW diff (uses different "scale", but it was displayed as 0.25 - which is now higher than PoW diff, LOL).

block time is so slow now after N changed.. takes ages to verify transfer  Takes a while for the difficulty to adjust, no recourse but to wait. Just another 108 seconds less and we're back at 60.  Also, top 50 richest addresses list updated as per request at http://yacointalk.com/index.php/topic,425.0.htmlSomeone now owns (at least) 0.6M YAC (out of 5.6M), cool! |

Changed the Y axis of the all-time network hashrate graph to logarithmic scale, in order to to able to see the current hashrate. |
|

|

Now with a countdown to next Nfactor change on the graphs page! (javascript required)
Also, added timestamp of last graph update.
|
|
|

less than a hour before Nfactor change  15 minutes  |

sairon: In yacexplorer, how often is the top stats (richest addresses, etc) updated? Looks like the numbers up there are form 6-1. Any way to update more frequently?
It's updated manually and the database queries take quite a long time to complete. |
|
|
|
Occassionaly, one of the images, two of them or all three images on the right does not show up.
It's a known issue. Usually it comes up on the next graph update (every hour). I'll look into it when I have the time. |

Caicos? what's this GPU brand?
Can you also post the command line? the thread-concurrency? Maybe you set the parameter not match with your hardware.
It's AMD Radeon 7470M. Works in Windows, though... Tried many options in Linux, even omitting all of the HW-specific ones but to no avail. In Windoze I'm using cgminer.exe --device 0 --scrypt --worksize 256 --lookup-gap 2 -I 5 --thread-concurrency 8192
and getting around 10 kh/s. |

Also, who has java enabled in their browser these days?
Oh, everyone? At least if you live in a country like I do, where all public, governmental and online banking sites are secured with a centralized java applet. Disable java and you have no way to interact with the government or your bank. - Michael Hah, gave me a good laugh, thanks! |

If someone could develop a web based miner I have some nice ways to help promote and distribute yac... anyone know where I would start on a script like that?
I am sure I have seen a java applet for mining Bitcoin but can't remember the name ATM. Also I don't know of anything that could mine neither scrypt that litecoin uses nor the scrypt variation that uses YAC- Most likely a Java implementation of scrypt-chacha will yield pretty low hash rates compared with an actual optimized SSE or AVX-enabled miner on the same hardware. Also, who has java enabled in their browser these days? |

YACoin uses address prefix version 77, see: https://en.bitcoin.it/wiki/List_of_address_prefixesOnce all YACoin have been mined, it will be functionally identical to LTC, FTC and BTC for that matter. The only exception is the faster transaction time, which comes at the expense of security.
Errm, I don't think any of us will live to see it as there's a 2 Billion cap. There's 3.3 M YAC so far, and IMO the generation will slow down considerably as PoS blocks take over. Like it or not, speculators are driving the Bitcoin market forward. This is a truly free market after all. And as there's no effective way of short-selling Bitcoin, all they can do is force the price to rise.
I don't understand what you mean. Don't miners sell their BTC for USD? This will drive the price down. You can also short sell Bitcoin by selling futures contracts on sites like icbit.se. But apart from that I disagree that Bitcoin is being driven by speculators. BTC is a widely accepted form of currency, and it has a thriving market. There are very things that cannot be purchased with BTC, unlike the alts which have no commercial support whatsoever. Frankly I don't see why they should have. - Michael I think we're both right. |

If you first have to exchange your YAC into CDN or USD, and then withdraw that money from the exchange, it will be highly impractical and completely unfeasible for small purchases.
Having a place to spend your YAC directly will increase its usefulness a great deal.
-Michael
I think we have bigger problems right now. Is that a fact? I actually think the biggest problem for YAC (and many other alts) is the fact that you can't spend them on anything. Their only value comes from the exchange rate with some fiat currency. These currencies are naked with no substance to them, which makes them a speculative instrument at best. If you could take 100 YAC and buy a meal at McDonalds, people would mine them for other reasons than to exchange them to USD. Some people might want their salaries paid in YAC rather than USD. And people with YAC in their pockets will create a demand for merchants to support YAC spending, which is the ONLY thing that will sustain a currency in the long run. If YAC is irrelevant as a long term currency, then whatever problems "we have right now" are in reality also pretty irrelevant. - Michael Well, first we need a much wider Bitcoin adoption... IMHO alternative cryptocurrencies are just for the "community", to test new features and come up with possible improvements for some "new" (read: widely-adopted) cryptocurrency (or become one). For me, the value of YAC is its innovation. And as far as the speculation goes - well, just look at some Bitcoin exchange rate charts.  Like it or not, speculators are driving the Bitcoin market forward. This is a truly free market after all. And as there's no effective way of short-selling Bitcoin, all they can do is force the price to rise. Seriously, you can't demand that everyone suddendly starts accepting a *coin that has been around only a month. Did your granny hear of Bitcoin? Maybe. Litecoin? Highly unlikely. Is anyone else having problems sending coins?
I've done all my mining on p2pool, and I can't create a transaction larger than 30 YAC. (I have 294 YAC in my wallet currently). ANything larger and is says failed to create transaction. When I try to send 30 YAC, it says I need to pay a transaction fee of 41 YAC!!!!!
Any way to get this fixed?
Thanks!
You have too many of too little inputs from p2pool mining. Every input is some 200 bytes on average when you try to send it, and also you pay fee for every single kB of transaction and the space in one block is pretty limited, so it might have just happened that you exceeded it. |

Since there is people already mining YAC with GPU. This only makes the currency unfair and insecure. So a public GPU implementation could only improve the security.
^ This. I agree. The fact that some are mining with GPU creates serious issues on exchanges. Price can not go up because there are constant dumps of thousands of coins even now when price is so low that mining with most CPUs is not profitable. So, on one side there is less and less CPU miners and on the other side there are few GPU miners making extreme profit and ruining the deal for everyone else. I have removed all my buy orders for now, and the next time I'll be putting them up it will be at 0.00003 or less. I had enough of paying 0.0003+ to support CPU mining, sorry. And then there are possibly some botnets or people who don't pay for electricity (and someone else does). |

what exactly do you have in mind that requires active developement?
agreed on the gpu miner, but oh well... would be a shame if we got 51%'d like FTC
An active wiki like the one's up for bitcoin and litecoin in their github account's. And binary release's on the main github account would be a nice start. Yacoin is orphan since the original dev is missing, but this should not be a problem since a distributed coin is owned by their holders and with consensus anything could be changed. Essentially I am talking about an *official* yacoin takeover. Well, WindMaster has been pretty active on his github fork, and as it's the only maintained YAC fork, I'd consider it pretty much "official". So Yacoin is not an oprhan, just the devs changed. Binary releases should not be a problem as long as someone trusted makes them. For the github wiki, I'd say that devs don't have time for it and nobody else can write it. But.. wouldn't that defeat the purpose of YAC, aka being mined only with CPUs?
Since there is people already mining YAC with GPU. This only makes the currency unfair and insecure. So a public GPU implementation could only improve the security. ^ This. Well, right now GPU is almost 16x faster than a CPU mining YAC...
That's not correct, please check the comments after the one where you saw that number. Will do. EDIT: Can't find anything. What do you mean? YAC already has some exchanges, like Vircurex and BTER.

Paying 200 YAC or 0.07 BTC for working WinXP 32-bit YACoin QT wallet compiled from latest source code. Communication over PM only until I
make sure everything works properly, there are no viruses and so on. Afterwards I'll post link for others to eventualy download and upgrade wallet.
Shame I don't have dev tools on my windows install (using linux) |

Well, right now GPU is almost 16x faster than a CPU mining YAC... So if someone decided to launch a 51% attack on YAC network, he would need approx. 103 GPUs (which is not that much if you consider GPU farms used to mine LTC). Also, GPU mining could stop working on August 13 th, but I would not count on that (IMHO it would become impossible in mid-2015 with *current* GPUs, considering the scratchpad size of 32M [at least on my GPU, considering I'm not completely wrong, which I might be ]). |

One thing that will help Yacoin is having a decent marketplace.
Currently, is there any one-stop location to look for people buying and selling with YAC?
We have trading for other crypto currencies, but there really needs to be a marketplace so people can do more with the coin.
There was a spreadsheet at one point. Is that all there is yet?
Is this subforum also able to be used?
If someone is looking to spend their YAC or has something he or she would like to try quickly selling with YAC, the overhead to put the item up should be very low, to encourage use beyond trading.
Yac does fit the need for miners who want an alternative to the GPU and ASIC rush.
Mining has been growing according to the recent network hashrate.
Plenty of people have acquired it through mining or trading.
Now let's make the Yac they've obtained work for them beyond speculation.
If Alice wants to sell an ebook for Yac, where would she go? If Bob wants to buy a Steam game for Yac, where would he go?
well, we can always fork bitcoin-otc as it's open-source https://github.com/nanotube/supybot-bitcoin-marketmonitorI don't think YAC needs a marketplace right now, as I don't think there is enough people to support it. What YAC needs ATM is : - A community driven place, a place where people can find the software and documentation (AFAIK the yacoin.org is not updated anymore and run by someone that has nothing to do with the original developer)
- Active development .
- A public GPU miner (otherwise the network is always at risk).
what exactly do you have in mind that requires active developement? agreed on the gpu miner, but oh well... would be a shame if we got 51%'d like FTC |

I believe YAC is a direct branch from NVC and I believe NVC is preparing to change how their POS reward is calculated on June 20th. Has there been any discussion, or thoughts, on changing how YAC POS?
None that I know of. Is there a way to generate vanity addresses for YAC?
Yes, just use the -X switch in vanitygen. EDIT: I've just generated this one: YACoinJ2PXNo6Q7rSMkZb5shaf82Wdbu5r  |

I have a question regarding POS. So for the amount that is currently being staked, so do you receive POS payments each day after 30 days? Or was the estimate of 20.55 coins for 5000 over the course of a month? Or what? I am confused how often and how much you get payed for POS. Is it a slow continual thing or does it only appear in large chunks? Is the estimate given for the entire year or just the period that they are staked or just one block? See I know people have explained how to receive POS but nobody has explained really WHAT POS functions like.
You stake some CoinYears, they get consumed and you get a few coins. So if you have only one unspent input in your wallet that is 5000 YAC AND it's at least 30 days old AND you're PoS mining, you will LOSE all you accumulated CoinYears (by spending the only input you have) but in turn you can REWARD yourself in the same block a given number of coins as an interest, in addition to the old coins being sent back to yourself. So in this case you get back your 5000 YAC, but with 0 CoinYears (they're brand new coins!) and ~20.55 YAC as interest (also new coins). And now you wait another 30 days to be eligible for PoS block with 5020.55 YAC input and (5020.55 + 20.63) YAC output. It works just like your bank account interest IRL, you get 5% interest per year with monthly * payments. EDIT*) Only if you have your client running at the time some of your inputs reaches 30 days of age. In reality, it can be delayed by up to 90 days without you "losing" anything, see below. However, if you don't launch your YAC wallet at least once every 90 days, you will be losing eligibility for some money. For example, you log in afer 120 days and you have an unspent input 120 days old. There's a cap in the GetProofOfStakeReward function of 90 days, so you will only get interest as if this input was only 90 days old, not the full 120. Hope that made it clear. |

Yup, started to get stake rewards on my wallet. Much higher than I envisioned it being too, yay! If you encrypt your wallet (which you should) https://bitcointalk.org/index.php?topic=187714.0 is helpful for anyone interested in how to generate stake. I just have a yacoind that runs on a linux server I have so that it doesn't rely on my windows workstation being up. Looking forward to getting my first PoS reward in approx. 10 days, a whopping 0.000188 YAC! |
