881  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoin 51% attacked? on: December 03, 2011, 12:19:26 AM
doublec, is there such a tool available right now?
Not that I know of. Usually I scan the chains using a block explorer but this is inefficient. It's easy for a merchant to know if they check their 'listtransactions'. They'll see that there are now deposits that were once confirmed showing as having 0 confirmations. Looking up the address and/or transaction in the block explorer will show the problem.

A 27 block reorg is definitely a scary sign but it can be done by accident. A pool or large miner become disconnected from the network and when the network goes up their blocks get released for example. I'd be more inclined to think attack however if there have been other reorgs. People accepting litecoin payments should check their 'listtransactions'. It's also wise to have their nodes detect a big reorg (ie. past their confirmation limit) and shut down until investigated. This is what I did on the i0coin exchange in the end to catch it.

There really isn't much money to be made right now to attack Litecoin with a double spend. I will talk to the exchanges to see if they have been affected by a double spend. And I will keep an eye out on the block explorer. Thanks CoinHunter for bringing this to my attention. I didn't know you cared so much about Litecoin.

I think it's more about this quote:

The hashrate does fluctuate a lot but I have not seen it drop 50% due to an attack. If I see that, I would of course warn people and exchanges of possible double spend attacks.
Hashrate fluctuating isn't a sign of a double spend attack. Reorgs are. What would be useful for all alt chains is a tool that analyses reorgs and shows transactions that are different from that and the main fork.

doublec, is there such a tool available right now?
884  Alternate cryptocurrencies / Altcoin Discussion / Re: SolidCoin Exploited. on: December 03, 2011, 12:06:43 AM
As usual though you're ignorant about many things SolidCoin, source was released not long after the binaries. Unlike perhaps Litecoin, people don't need to worry about Trojans with SolidCoin, only one person makes the binaries and we have done so for nearly 6 months without any issues, we have a history of being safe.

LOL. You sound like Bernard Madoff.
885  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoin 51% attacked? on: December 02, 2011, 11:53:41 PM
The litecoin network hashrate has stayed around 20 mhash/s for a few weeks. This week, it has climbed to 32 mhash/s. From what I can tell, this is due to people abandoning SolidCoin after the exploit was found and the price tanked. There are a lot of miners not in on a public pool, but there's nothing wrong with that. The hashrate does fluctuate a lot but I have not seen it drop 50% due to an attack. If I see that, I would of course warn people and exchanges of possible double spend attacks.

Coblee is aware of it and seems to be hiding the fact this imminent 51% threat exists to Litecoin.

Stop accusing others of crap. I guess you are just trying to throw some FUD around to deflect the negative attention SolidCoin is having recently.

Any interest in physical litecoins?
https://bitcointalk.org/index.php?topic=53596.0
Please discuss in that thread.
887  Alternate cryptocurrencies / Altcoin Discussion / Physical Litecoins on: December 02, 2011, 11:36:33 PM
I think Mike Caldwell's physical bitcoins are really cool. I talked to him about creating a bar for storing litecoins.
See this for what his bitcoin bars look like: https://bitcointalk.org/index.php?topic=53203.0

Then I thought that it would be even cooler if the bar was silver plated and had an 'L' etched in it instead of a 'B'. It seems like in order to do something like that, we would need to order possibly hundreds of these bars. I want to know if there's any interest in this from the Litecoin community. I'm guessing the premium on each bar would be at least $20. Let me know if you are interested and about how many bars, and what denomination would you be intersted in. Obviously a 100 LTC bar does not make much sense as 100 LTC is like $2. To me, 10,000 LTC seems like the right denomination.

Quote from: RealSolid
SolidCoin v2.02 has been released. This is a mandatory release, you will be unable to move past block 91500 without it.

This is the central control that doomed SC 2.0 the moment it was launched.

One hour notice for a mandatory binary-only update. Really?!?

RealSolid constantly attacks Bitcoin saying that businesses will never accept them because of a possible 51% attack. Does he really think businesses will accept solidcoins when he keeps pulling this kind of crap? They would have to upgrade with an hour notice to a binary that could contain trojans. And there's no recourse. No source code to check and compile themselves. If they don't upgrade, they can no longer transact in solidcoins. Awesome.

Apparantley I have been demoted as moderator, and basically banned from the Solidcoin forum.
This is for speaking "bad" about RS.
http://solidcointalk.org/topic/482-solidcointalk-mod-bashing-rs-at-bitcoin-forum/

Honestly, you should not have been surprised. RS is quick with banning people on IRC. And there has been many cases of him censoring stuff on his forum. Say something bad about SC and RS on his forum, you will find yourself banned and your posts censored or cleaned up. Say something bad about SC and RS here, do you really expect to still be a moderator on his forum? Smiley

I assume that doing a shared private key means that if I lose my half of the key, then the bitcoins will be lost. That sort of defeats the purpose of these physical bitcoins where having the physical untampered coin means that you have access to the stores bitcoins.

Why I'd like to see us to have another 3rd party create a complementary coins that has the other half of the keys. Then these 2 coins will be a matching set.

The gold coin will probably come in a capsule, gift box, or other container, and will in practice almost never be separated from it.

This is purely a collector's coin - a coin that will pretty much NEVER circulate as "bitcoin currency" due to its nature, so I'm willing to take liberties that wouldn't make sense for the smaller coins that someone could "receive" in a transaction.

Solution: Print the code on a clear label, and put it on the container.  Problem solved.  If someone else besides me had a laser etching machine, they could etch the code into the acrylic capsule, and it would look clean.  But that sort of defeats the purpose if I'm the one making the coins.  Seems to me someone with a $5k budget for a coin might be able to find a local engraving shop to engrave the key on a plaque or capsule or other object so it looks nice.

It's the buyer's coin after all... if buyer wants a single private key because having a secondary object defeats the purpose, I'll be happy to provide it with a single key, and will never steal his bitcoins.

How safe is using the 2 keys method? I'd hate to have the 2 public keys show the amount and then when I try to redeem it years later, I find that the 2 private keys don't really work together as expected.

It really sucks that Solidcoin started as a good project, and has turned into this complete shit fest. I stayed away from iXcoin, and i0coin for obvious reasons, but SC was the first "real" alt-coin this forum ever had. I have come to the conclusion that the way RS has conducted himself has not benefited SC or any of it's investors...

You used to be a diehard SC supporter. What changed your mind? What has RS done recently?
893  Alternate cryptocurrencies / Altcoin Discussion / Re: (Issue Solved) on: November 30, 2011, 02:22:24 AM
issue is solved Grin.

Yes, the old client was trying to spend all those 0.00000001 litecoins in your send. This caused the transaction to be huge and that's why the transaction fees were 2.2 ltc. With the new client, all the transaction spams are ignored when sending coins.
894  Alternate cryptocurrencies / Altcoin Discussion / Re: over 10% fee for 1 Litecoin transfer! on: November 30, 2011, 01:31:35 AM
Do you have transaction spam in your wallet and are you using the latest client 0.5.0.8?
895  Alternate cryptocurrencies / Altcoin Discussion / Re: All my fairbrix just went somewhere by thremselves.....WTF! on: November 30, 2011, 01:03:35 AM
This problem really only affects fairbrix and tenebrix. Lolcust released tenebrix with a default config file that has a default rpcpassword and I didn't change it for fairbrix. There's a reason why bitcoin does not have a default rpc password and forces you to set one the first time you try to use RPC.
896  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 30, 2011, 12:59:40 AM
For those of you using the Litecoin p2pool, forrestv has released an update that will make things better. You must update before Dec. 2, or else your p2pool will not work properly. See this thread for more details: http://liteco.in/threads/130-kh-s-distributed-litecoin-pool-using-p2pool.29/

And if you have not tried p2pool yet, why not give it a try?
897  Alternate cryptocurrencies / Altcoin Discussion / Re: [Announce] Fairbrix relaunched! on: November 29, 2011, 12:40:32 AM
Is fairbrix succceptible to the tansaction spamming that hit Litecoin?  If so, could it be possible to get an updated Fairbrix client?  {Is TBX need updating too?}

I dont think anyone is working with Fairbrix any longer. Coblee moved onto litecoin so unless someone forks litecoin's code I dont think this will be patched..

TBX is in the same boat. Lolcust will need to update it though i havent seen any updates at all.

Yes, both fairbrix and tenebrix are susceptible to the same transaction spams. I do not plan to update fairbrix with the fixes. If anyone wants to keep fairbrix alive, feel free to take over.
898  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 28, 2011, 11:47:37 PM
when i try to send small donation to coblee i get : error: {"code":-4,"message":"Error: Transaction creation failed  "}
the goal is to empty out the old wallet.dat cause its over 51 Mb in size with only small amount in it because of the nasty spamming

If you have less than 0.01 LTC in your wallet filled with transaction spam, I would suggest that you just throw that wallet away. Sending those coins will cost you more in fees and further bloat the chain.
899  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: November 25, 2011, 10:12:45 PM
You're right. As long as the spam transaction issue is fixed. We shouldn't be growing faster than Bitcoin.

Can you please continue this discussion in the previosly mentioned thread?  This is the litecoin thread and that one is dedicated to this discussion.
The discussion is related to a current issue with Litecoin, the growing block size.

The Litecoin block chain grows about 4 times faster than Bitcoin. So this may become a problem for us sooner. It's good to hear some ideas about how to fix it.
