Auto update is unsafe, because i (or someone else) can push out a malicious update.
So.... Is this one a malicious update?  Wink

It's better if each user decides for themselves whether or not to upgrade.
Should I upgrade?  Smiley

Check my past history and see if you trust me. If you do, then you should upgrade to the latest binary.

I would suggest that everyone build their own clients from source if they are able to.
And you can easily see from the source that nothing malicious was added to the bitcoin code:

New code released with lock at block 8064. Please update your clients to protect against attacks!

Windows client: https://github.com/downloads/coblee/litecoin/litecoin-windows-client-40103.zip

Daemon coming soon!

any chance the next client can have an auto-update capability?

Client doesn't connect.

Does anyone know a node I can add?

look at your debug.log file and see what's going on.

Your network hash rate is increasing, in 10 minutes you have gone from 1.5 Mhashes to 2.5 Mhashes, you are under attack.

Where do you see that it went from 1.5 to 2.5? After the difficulty increase, getinfo showed me 2.5 after 120 blocks.
1127  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Litecoin - a lite version of Bitcoin. Launched! on: October 13, 2011, 08:43:12 AM
Cool, I will pull it down.

Majestik over at SC has made the mention, he is the only one with enough horses to do it.

He knows he cant hang with BCX though  Grin Grin Grin

What kind of attack do you think they can do? If it's a "build a longer chain in secret" attack, we won't even notice it, right? If we notice an increase in hashrate, it's just someone trying to mine legitimate blocks, right?

We're finding a block about every 7 seconds now. It will take about 2-3 more diff increase for things to match up.

@Coblee,

It appears that someone is trying to 51% you, I saw the jump to 1.5 Mhashes in a matter seconds so I brought 600K online to make it that much harder.

Actually I don't think anyone is. The jump you see is because there were too many orphans before and it was underestimating the real network hashrate. After the diff increase, it's more accurate now.

Just commited new lock for block 6048: https://github.com/coblee/litecoin/commit/a02d6ab11537ed5d869790f6906131edfc5cbcee

Windows client binary coming soon.

EVERYONE, please update to the newest code. It's locks block 6048. getinfo will show version 40102 if you are on the latest.

Windows client binary: https://github.com/downloads/coblee/litecoin/litecoin-windows-client-40102.zip

I've asked twobits to build the windows daemon. I've asked him to post the link to download that here when he's done.

I am mining very smoothly , do I need to update?

I just checked in code to lock in block 4032 after diff change.
Please grab latest source. Windows client coming soon.

Windows client here: https://github.com/downloads/coblee/litecoin/litecoin-windows-client-40101.zip

Everyone please update.

Unfortunately twobits is asleep and can't help me build a windows daemon. And I only trust him to do that right now.
So for those running on the daemon, you can stay with your current binary. As long as enough people are running the new build, we should be good against an attack. Thanks.

To check to see if you are running latest client, getinfo should return version 40101.

If you don't want to get wiped out by a 51% attack, you should update. Just stop and the start the new client. You will be down just a few seconds.


Coblee,

Not meaning to be picky but you cannot update against a 51% attack. You can hard code the lock in, but that is it. The only thing that protects against a 51% attack is hash power, that's it. With your lock in you can back to a restore point basically after the 51% attack has concluded or enough miners update with a client that recognizes the proper fork only.

~BCX~

Yes, I know that. But updating to the latest lock will deter an attack that was starting on a block before the lock. So it does help. And when that happens, the chain will fork. So if enough miners get the latest code with the lock, they will be on the proper fork. And I expect eventually pools and exchanges to be on the proper fork, so there's no reason for a miner to not update their client and stay on the attacker's fork.

Since we know that hash power protects against 51% attacks, right now there's way too many orphans due to the difficulty being low. So if an attacker is building their own chain, they only need ~900mhash/s to succeed even though our current network hash rate is much higher than that. So that's why I will keep doing the locks until the difficulty catches up.

So how often are you going to lock in blocks?  Every retarget will get a bit out of control I'm thinking.


I will lock in the next retarget 6048 and then I will go to sleep and maybe another lock in when I wake up. We'll see. Once the difficulty catches up to the network, it would be harder for us to get attacked.

Sp0tter, thanks for adding Litecoin. One suggestion I have is can you add the difficulty column in the second table? Not sure why it's in the market table. That way coins without an exchange will also show current difficulty.

The miner you are given doesn't have required files, keep on saying that libe is missing, this lib is missing ....
How many version or times, i have to download windows client & windows daemon.
Its seems more than 4-5 times downloaded & now dont even know which is the correct version & which i have to run.

Hrm.  One more try for the windows guys, this time linking static?

I reported this problem earlier, you need to download libstdc++-6.dll and libgcc_s_dw2-1.dll and put them in the daemon's folder.
I downloaded mine from mingw, it took some time, you might also find them on google (I don't know a trusted site except mingw).

You need these 2 for the miner? Please upload yours to mediafire.com and I will add them to the miner zip file.
