I guess going up by 15% is dropping constantly by your accord

One last thing. Was gonna use litecoinpool.org or whatever its called but it was full so I'm on notroll.in. Have they a decent reputation among the community? Notroll is what I use notroll.in is fine, stratum - very low stales, but im getting around 1-3% invalids. it is the pool i was using when coinotron was down. coinotron is the best in my opinion but notroll is a very very close second. I use 2% rbpps on coinotron now.
I get 0.4% stales and no invalids on notroll.in using stratum, play with your settings |

So an ASIC can be built specifically for litecoin?
Yes, but it's significantly more difficult than for BTC and will likely not be 100x faster/more power efficient See www.tarsnap.com/scrypt/scrypt.pdf |

The later drivers/app sdks seem to get a little less kh/s for me (although also less stales), so I'm not sure if you can get more out of those cards. 270 KH/s is pretty good for a 6850, I used to get 290 KH/s out of my 6870.
And, yeah, don't bother with CPU mining, it's a waste of electricity as GPU mining is about 5-6x more efficiency.

No, miners with GPUs will either stop mining or move on to litecoin. Mining LTC is already 30% more profitable for me, I don't know why anyone would still be GPU mining BTC at this point.

Do you plan to get stratum? I'll bring my 2mhs back to your pool if you do

exchange is very nice. i sent some useless nvc to it.

Good that you said that you don't understand Litecoin at all.
It has a small difficulty because it use the Scrypt, and not the SHA256 method.
The small difficulty is actually a result of the faster block generation algorithm. Actual difficulty in terms of number of trailing zeroes for the block header hash is different. |

No, your router is caching the old DNS entry. Reboot your modem/router/PC and you won't need a VPN. If you know wtf you're doing, you can try just flushing the DNS cache.
Done that, still can't. |

My IP is banned, I can access through VPNs though

cough..bullsi..cough
I started mining with 4 5x7970rigs (9.3mh) a few hours after the coin showed up on coinotron for 24 hours. I have less then 250 nvc.
You only made a bunch if you mined before then.... without getting exact, i think i started mining on the 5th day of the coins life. when coinotron was at 45hm and diff was at 4.1
so, no you could not mine 10k unless had a huge farm...... or mined in the first 2 days
I got 500 coins with 2 mh/s within the first 16 hours after release of binaries scammity scammy |

Right, it reflects the difficulty in reading the blocks byte-to-byte as is I believe. When you build the sql database it even tells you that it's truncating the data at the end. It's not checking the merkle roots at all so of course everything checks out. As far as I know Abe only computes the SHA256 hashes. See: datastore.py hash = util.double_sha256(
ds.input[ds.read_cursor : ds.read_cursor + 80]) In order to verify all transactions belonging to the root you need to add a python scrypt implementation to calculate the hash here. You can find that here: http://pypi.python.org/pypi/scrypt/0.5.4Additionally if the hashes are of the full data in the tx you'll need to adjust the length of the data it reads between each hash, as there's extra data (nTime) in the PPC/NVC hashes |

I doubt any of the LTC community has anything to do with this, as it's happened to LTC in the past. My guess is someone wants to take control of the NovaCoin chain, which is what happened with LTC before too. The intention is not to fork the chain but get as much nvc as possible while no one else has it or can figure out the value. Ddos attacks are cheap I'm told, so if you have a massive farm it makes sense finacially (but not legally...).
What I have a problem with is that balthazar and btce told no one about their premine until I dumped and looked at the blockchain and then made a post here.

Here you guys go http://www.multiupload.nl/RPHLDYLTA9open with sqliteman on unix If you want to compile your own abe webserver, here are my hacks: conf file: datadir = [{
"dirname": "/home/me/.novacoin",
"chain": "NovaCoin",
"code3": "NVC",
"address_version": "\u0000" }]after line 67 {"chain":"NovaCoin",
"code3":"NVC", "address_version":"\x37", "magic":"\xe4\xe8\xe9\xe5"},later in the code, bypass doing hashes to make sure the merkle root is consistent (hack for litecoin/scrypt) class InvalidBlock(Exception):
pass
class MerkleRootMismatch(InvalidBlock):
def __init__(ex, block_hash, tx_hashes):
ex.block_hash = block_hash
ex.tx_hashes = tx_hashes
def __str__(ex):
pass
#return 'Block header Merkle root does not match its transactions. ' \
# 'block hash=%s' % (ex.block_hash.encode('hex'),) # Verify Merkle root.
if b['hashMerkleRoot'] != util.merkle(tx_hash_array):
pass
#raise MerkleRootMismatch(b['hash'], tx_hash_array) Check for nTime for all transactions, a feature that most other chains do not possess def parse_Transaction(vds):
d = {}
start = vds.read_cursor
d['version'] = vds.read_int32()
d['nTime'] = vds.read_uint32()
n_vin = vds.read_compact_size()
d['txIn'] = []
for i in xrange(n_vin):
d['txIn'].append(parse_TxIn(vds))
n_vout = vds.read_compact_size()
d['txOut'] = []
for i in xrange(n_vout):
d['txOut'].append(parse_TxOut(vds))
d['lockTime'] = vds.read_uint32()
d['tx'] = vds.input[start:vds.read_cursor]
return d
def deserialize_Transaction(d, transaction_index=None, owner_keys=None):
result = "%d tx in, %d out\n"%(len(d['txIn']), len(d['txOut']))
for txIn in d['txIn']:
result += deserialize_TxIn(txIn, transaction_index) + "\n"
for txOut in d['txOut']:
result += deserialize_TxOut(txOut, owner_keys) + "\n"
return result These are kind of dirty hacks, but it runs for me |

I don't recall seeing a transaction like this in the first 2000 or so blocks, but you guys can have a look later today. I will upload the sqlite Abe dump of the blockchain in this thread soon.

When novacoin was posted here on the 11th, there were already 210,000+ coins mined. Where did those go? The details for novacoin were first posted in the russian forum on the 10th: https://bitcointalk.org/index.php?topic=114712.0Here is the timestamp for the genesis block: 1360105017 (02 / 05 / 13 @ 4:56:57pm EST) Here is the timestamp for the first block: 1360426882 (02 / 09 / 13 @ 10:21:22am EST) Block 1500: 1360475877 ( 02 / 09 / 13 @ 11:57:57pm EST) Reward is as follows: nReward = 100 / (nMaxTarget / nCurrentTarget) ^ (1/6) At block 1500 we have some 110,000 coins mined (max block reward is 100 and decreases with difficulty; at block 1500 reward is 62.580000), and it goes down with every block. This was all mined before February 10. Balthazar (alexhz) uploaded the source to github on the 9th and didn't appear to announce it. In fact, binaries didn't even appear until the 10th. Here's a post of Balthazar showing already 500+ blocks mined before release: https://bitcointalk.org/index.php?topic=114712.msg1512980#msg1512980 |

Preparation for the pump and dump. Notice that there are some 500-2000 BTC walls that keep moving up. There's a bot that's manipulating the price by constantly moving the wall up and pushing small buy orders in front of it.
If it's anything like LTC at introduction (when the same thing occurred), they will push the price up to about 0.010 BTC and then slowly dump as others put buy orders up. This will happen in about 1-2 weeks.

My guess is artforz couldn't figure out how to code a GPU miner effectively. The key to reaper's code is to effectively halve the size of the lookup table (lookup_gap = 2) and read sequentially in order to achieve the fastest hash rate. If you use the entire lookup table in RAM (lookup_gap = 1) you lose about 40% performance, which was much closer to what artforz was originally quoting for GPUs when the chain opened.
There are threads later where he admits he was wrong after Litecoin's release. So, there's no need for conspiracy theories or even coblee to sit around and try and prove there was no premine.

A strange thing to do, release a coin that cannot be mined right now and have it available on the exchange.
If it is unminable then how does BTC-E have Novacoins then?
How did they mine or get them?
Does this sound like a way to make people spend their Bitcoins buying them as they cannot be mined?
This are just questions and I have no opinion either way, just speculation.
Balthazar released it yesterday on the network during which time some russians mined 200,000 or so coins, then today when it was added to BTC-e everyone started trying to mine it. Because of the retarget algorithm stale rate even solo mining right now is extremely high (getwork takes forever, so a lot of people's hashes are useless). see this thread https://bitcointalk.org/index.php?topic=114712.0Right now it's a lot of solo miners fighting amongst each other to get as many blocks before the difficulty heads into the double digit range. People are still getting blocks, but only those with massive hash rates because getwork takes so long. It's the same problem with every alt coin release that doesn't have a suitable difficulty adjustment algorithm. Sadly what is happening right now is basically a premine amongst the parties who have the greatest hash rates, since the probability is that they will obtain the majority of the blocks The russians have it right Classic skamkoin |
