i7 CPU have 8 threads. Total is in this random example 62h/s and PC (CPU) is also running some other things same time. If minimize all possible CPU loads it may give around and even over 10h/s  x 8

Who wants to sell some YAC?  So far I've purchased another 1 million YAC from various people after I posted my offer to buy at 0.0000008 BTC/YAC (roughly what Cryptsy was trading at when things went tits up) on the previous page of this thread, and I'm game to buy some more.  While I see the price is trading higher on BTER, just try to deposit or withdraw YAC to/from BTER and you'll see the problem!  I'm ready to buy lots of YAC and you'll actually get BTC rather than just hope BTER comes around.

What happens if it is on no exchange, how do people buy/sell then?

Here's one way:  I'll buy up to a million YAC at 0.000 000 8 BTC/YAC, which I think is a hair higher than Craptsy was trading at toward the end.

I'll go nuke Craptsy off the first info post of this thread.

You know, given that there are currently only a handful of YAC nodes running, it might not be difficult to narrow down the malicious miner by observing which node(s) introduce(s) which blocks to the network and when...

Wrt to luke-jr's attack it wasn't this. He simply had the difficulty shoot up, and then left, leaving the altcoin issuing one block every X days, rendering it pretty much unusable.

Perhaps we're discussing different altcoins that Luke-jr has attacked.  He did 51% CoiledCoin using hashrate from Eligius to merge-mine CoiledCoin without the knowledge of the miners using his pool, and minted blocks with no transactions.  Perhaps the high-difficulty stranding you're referring to was a different alt.

Well, perhaps if by "mine for a while", you mean "51% the coin while excluding anyone's transactions from the mined blocks", then that would be pretty close to what happened (if I remember correctly).

Totally not.
With a 51% attack you can at most make half the blocks empty, not "exclude anyone's toes from mined blocks".

Nonsense.  If you simply ignore everyone else's blocks, you can make *every* block empty as long as you have at least slightly more hashrate than everyone else, by mining your own blockchain in isolation from the network and leaking it out to the other nodes.  If you have at least slightly more hashrate than everyone else, eventually your blockchain (with every block empty) will win.

Mining on top of other blocks found by other miners would pretty much defeat the purpose of a 51% attack.  That would certainly be "amateur night at the 51% party."  A correctly executed 51% attack mines on top of the attacker's own blocks, so they can override everyone else's blocks when their alternative blockchain with a higher chain trust is introduced to the network.

I wasn't following it closely (and was a little disgusted) but as I recall, all lukedashjr did was mine for a while then quite and it had a devastating impact on whatever coin it was.  Hell, the same thing could happen to Bitcoin without any attack if the price drops steeply or suddenly (but that could never happen, right?) and/or a few large clusters were molested.  I'll call this an 'Invisible hand of Adam Smith lukedashjr Attack.'  Maybe the adjustment algorithms have been patched up to preclude this, but I doubt it...such things occurring proactively seem rare in Bitcoinland.

Someone wanted out bad! Dropped over 1 million across the exchanges at ridiculous price values. I hope for his sake he was trying to get out of crypto entirely versus jumping on the bitcoin sinking ship. I don't see the point of doing that unless you are desperate. Anyone want to admit to it on here?? ;p

LOL, if anyone wants to drop a mega-YAC (1 million YAC) at ridiculous (or even reasonable) prices, just send me a message and I'll save you all that hassle of dumping it on the exchanges.

YAC/BTC and YAC/USD trading pairs are now on www.crypto-trade.com ! Per usual, I urge you to not keep substantial amounts of coins on any exchange. I am cautiously optimistic with cryptotrade, and it is great to be able to trade directly for USD.

Would you be interested in setting up a mining contract? If not I will probably have to buy on the exchanges as well.

Thanks for asking, but naw, I think I'll continue mining and hodling everything I mine.  Shouldn't be too hard to snag 500K on Cryptsy if you're willing to spread it out over a few weeks.

In other news.. I am looking to buy 500,000 YACs. Send me pm with serious offers.

A short while back I posted that I was interested in buying a megaYAC (1 million YAC), though serious offers definitely weren't what I received.  One person wanted 3x or 4x the going rate on Crypsty and BTER, and another asked for 10x higher than the going rate.

Did you get any actual serious offers to your inquiry?  I ended up just buying that amount on Cryptsy spread out over a bit of time, and then have mined another megaYAC (tm) in the meantime.

I wonder if there is so much solo miners?

Yes.


Example I do not want solo mine (and also not know exactly how to do it)  with my poor average 2.8kh/s hash power (only this amount I can use for YAC because my R9 280x rigs really are not at all for N16 (they can but N16 is really not for these radeons)

How can find p2p nodes? In YAC coin information side and here page one many links are obsolete.
It is not good for coin in long run if it is some kind of "insiders club". Informatrion need be updated.

Setting up solo mining is not particularly difficult.  Getting the actual miner up and running is the hard part, and you've already got that covered.  If you're running the YAC wallet too, then you're 95% of the way there.  With 2.8kh/s, there's not much reason to be afraid of solo mining.  Pools are useful when your hash rate is low enough that you'll rarely mine a block on your own or can't take the risk of a long dry spell due to variability, but at 2.8kh/s and the current difficulty of 0.0012, you're likely to average about 30 minutes per block found.

After the last N change, I cranked back up quite a few otherwise-idle blade servers CPU mining YAC to keep things moving along after a lot of GPU miners stopped mining and to shift the balance of hash rate away from certain pools having too large a share of the overall hash rate.  So, at least some portion of the apparently large non-pool hash rate is me solo mining at the moment.  Thirtybird is probably another good chunk of it.  Granted, I'm mining at a loss (in terms of power cost), but I'll probably leave it going for the winter for a little extra heat in the building the servers live in.

Seems like a bit of a failed launch of this new fork and wallet, given that it hard-forked over to parameters incompatible with the official Elacoin wallet at least 12 earlier than advertised, and before anyone did a thorough examination of the source code of this new wallet.

The inflation is now 118% pa, or 10% per month, not counting POS.

The inflation decreases over time as the number of mined coins over time becomes a smaller and smaller amount relative to the overall number of coins in existence.  Look at what it will be a few years down the road.


The top miner at coinmin.pl is getting 84k YAC per day. If the community doesn't do anything YAC will get the reputation that saver's value will be wiped out by a few miners when diff is low.

The top miner at coinmine.pl is investing a large amount of hardware resources and power to get those coins.  The block reward they're receiving isn't vastly greater than the block reward was during YAC's hash rate peak.  Your proposal is to slash their return by more than 1/2 and just cross your fingers that price of YAC rises by an equivalent to compensate, for the purpose of increasing the value of early investors?  Sounds more like a recipe to drive away more miners, who are already in short supply.  Note, I hold a pretty large quantity of YAC at this point (not quite a million YAC yet though), and even I would be opposed to this change because I've seen numerous other alts try to change their block reward to enrichen the early investors / hodlers and/or penalize miners that came later.  I have yet to see that work out particularly well..

There's already a cap on the block reward in place.  I would be more worried if there were not, or if modern miners were getting an order of magnitude higher reward now or something, but that is not the case.  The sky is not falling.  All alts are decreasing in value at the moment.  Hard forks and changes to the basic parameters of a coin should be a last resort reserved for extreme circumstances.  Note that the YAC community is still alive even though we still have the same basic reward parameters that the coin started with.  We prosper by knowing when to keep our hands off the basic parameters of the coin for the purpose of favoring a select part of the community's participants.  The way the reward calculation works and is capped wasn't a mystery that was suddenly sprung on everyone recently, it is the same as it has been since the beginning and anyone choosing to participate in YAC should have known what those parameters were when they became involved.


YAC survives to this day was not because someone stuck to the original release, but because someone went ahead to keep working and improving.

Was me?  The very first thing I did after forking the YACoin source was not to go changing the reward parameters.


For a starter, I suggest we change the cap to 25 which effectively sets the index to 0 when diff<=1. The cap is reached when diff<1 . Maximum inflation will be 49% pa. It's still pretty bad but if it is too low the miners aren't too happy. That said if a miner likes YAK YAC, he/she should like low inflation; if she/he doesn't care, then feel free to mine something else.

Translation: "I'd like to hard fork your coin to change the block reward so early investors and miners have a larger advantage over current miners.  And if you don't like it, feel free to mine something else."

Is that a fair translation?

You'd need about 2kbps to download seven 1MB blocks an hour.  That's a lot of bandwidth 24/7/365 on a global HF network.  I think the Bitsat project and the use of UHF and SHF for a lot more relative bandwidth is the best solution for a global wireless network - https://bitcointalk.org/index.php?topic=334701.0

6 blocks/hr * 1048576 * 8 = 50331648 bits/hr

50331648 bits/hr / 3600 seconds = 13981 bps = 13.981 kbps   (with no additional overhead)

For 7 blocks/hr, 16.311 kbps   (with no additional overhead)

These rates exceed conventionally available AX.25 packet radio / TNC throughputs for HF and VHF ham bands (generally 300 baud FSK for HF, and 1200 baud AFSK or 9600 baud AFSK for VHF/UHF).  Either use of higher frequency bands or a custom modulation format that would tend to have a bandwidth exceeding amateur radio rules in most ITU countries on HF, VHF and UHF frequencies would be needed.  At that point you might as well just set up a 900MHz, 2.4GHz or 5GHz 802.11 link.


Yes, anyone can tune in to listen to ham radio, but it's important that we have parts of the radio spectrum to ourselves, otherwise all frequencies from DC to daylight would be licensed for commercial and public safety (much of which isn't listenable without buying horrifically expensive gear, if it isn't completely encrypted for no reason other than to eliminate transparency) use.

$10 to $15 for a Realtek-based DVB-T USB receiver dongle used as an SDR (software defined radio), and you can receive whatever you want from 24 to 1766MHz (in the case of versions of the dongle using an R820T RF front end).

Re: [ANN] Fibonacci SCRYPT ASIC Litecoin LTC Miners - Community Driven
by

on 14/07/2014, 17:34:58 UTC
Anyone know whats really going on with Fib? I've been following this thread this Dec of last year, its been quite some time...

To my knowledge, from having worked on numerous VLSI/ASIC projects (and thus knowing the development process and realities of getting from idea to trays of packaged dies on your desk), and from looking at the thread over on litecointalk and jasinlee's comments about where they're at..  I don't believe they have actually finished the design and taped it out for a prototype run yet, which would need to happen before they even know if the design works.  Let alone scheduled production quantities with a fab after verifying the prototype functions and performs as expected, which is generally a long lead-time proposition.

That's my viewpoint from having undertaken scrypt ASIC development late last year.  Only we spun our own ASICs for our own mining operation, not to sell to others.  The oft-repeated "the merchants get rich off the miners backs" analogy is applicable to gold mining in the 1800's.  In the context of cryptocurrency mining, that's just silly.  The ones that actually won are the ones that got there first while difficulty was still nice and low.
