Heya,

Today we added Litecoin (LTC) as a payout option on our multipool, www.xpool.ca

We will also soon add so it can also be mined directly.

Cheers!

Did Litecoin testnet forked?

On my test machines {no real money or important data involved} I noticed that Macintosh 0.10.2.2 is at block 641381, whereas the Windows 0.10.2.2 is at block 641439. Litecoin mainnet and both Bitcoin nets are still staying in sync on the same physical hardware.

Those are test machines, so I blew away 'chainstate' and 'blocks' directories on Macintosh and restarted the synchronization with -connect to the Windows machine. The synchronization stalled at block 640000 with repeated errors:

ERROR: ContextualCheckBlockHeader : rejected nVersion=2 block
ERROR: invalid header received

The synchronization went 381 blocks further when I removed -connect and let it synchronize from the Internet.

Anyone here knows what is going on?

There was a soft fork yes, you can read the latest post from the devs on it. https://litecointalk.org/index.php?topic=26151.0

There was a soft fork yes, you can read the latest post from the devs on it. https://litecointalk.org/index.php?topic=26151.0
I'm not sure if we are talking about the same kind of fork. I'm talking about the two valid branches both running 0.10.2.2 code. Yesterday I had this reproduced with one machine at 0.10.2.2 Macintosh and the other 0.10.2.2 Windows. Today I added another copy on the Windows machine (running as another user). This way I have exactly the same code running on the exactly same hardware, the only difference are directories with the data and port numbers for the network traffic.

The fork starts after block 641334, the first different block is 641335.
Code:
C:\>litecoin-cli.exe -rpcport=19332 getblockhash 641334
745c3628a41b53b115add71ca304e0c3711447635a113a735b9d3c0357fb5ee9

C:\>litecoin-cli.exe -rpcport=1 getblockhash 641334
745c3628a41b53b115add71ca304e0c3711447635a113a735b9d3c0357fb5ee9

C:\>litecoin-cli.exe -rpcport=19332 getblockhash 641335
87dead3220e76a9b9a0422904bd17f3d3727236e4dbaf12d01f7ea186c7fd669

C:\>litecoin-cli.exe -rpcport=1 getblockhash 641335
2c90e25ac93447ab179f5dccd4ac776d79cb924048927bdfdad250eb012ad91a
Those aren't trivial short forks, they are several hundred blocks long
Code:
C:\>litecoin-cli.exe -rpcport=19332 getblockcount
641756

C:\>litecoin-cli.exe -rpcport=1 getblockcount
641435
although the comparison above isn't completely fair, because I was starting and stopping those tasks as well as opening and closing respective network ports in the firewall (external to Windows).

Can someone with an account at litecointalk.org repost this message there and ask for the comments from the developers?

My thinking is that if somebody managed to split the testnet that far there maybe a bug lurking in the code that could be used to split the mainnet.

Do you guys ever see LTC going to BTC prices in the coming years? I know no one can say for sure but what are your thoughts?


What use case does LTC have coming?

Are companies going to accept it ever like Alienware?

If Bitcoin will go to the moon, lets say 10,000 USD, then Litecoin will follow and reach 100-200-500 USD as well. Its not about merchant acceptance its about human behavior and its like Gold-Silver relation. There are a lot of people around who do not have money to buy Bitcoin at 10,000 USD or not even at 1,000 USD, so they will choose the second candidate, Litecoin!

In conclusion, if Bitcoin will skyrocket, Litecoin will follow, thats for sure!

That can be any other shitcoin with a big community, we'll see Smiley

I dont know, there are 3 coins what have prove themself in the last years, that are bitcoin and litecoin, also dogecoin what came later is still in the top.
All other coins are pumped and dumped to the top, the only 3 u see always in the top 5 are bitcoin, litecoin and dogecoin.

Bitcoin = accepted and world wide ( everybody knows bitcoin )
Litecoin = almost accepted + more coins
Dogecoin = massive coins

all the 3 coins got something what the other from those 3 dont have. So i think this is not just something from the last year(s) but also something for the comming years, those coins has proved themself to be the best of the best.

All other (mined) coins u see raised to the top, get traded for bitcoin/litecoin or dogecoin and are out of the top and dying slowly. People dont take other coins outside those 3 serious, the only thing they want is trade it for those 3. (pumped and dumped)
Also big community's from those ''shit''coins (how u called it Cheesy ) are there just for the pump and waiting to sell it for bit/litecoin or dogecoin. Just an example: navajocoin, big community what try to show the rest of the people that navajo will take over all the coins and will be the best of the best. Dev's posting sometimes: big news is comming, community says it's the best coin what will be world wide known as the best of the best.. And navajo will be the future from crypto..
It's nothing else like shittalk, pure words for pumps so the devs / ''loyal'' community will dump coins for bitcoin.

Its not only navajocoin what is pure a scam pump and dump, but also almost all other coins. Only thing people want are bitcoins



Litecoin just got pumped, don't know what you're talking about. What about monero, dash, bitcoindark, etc etc....

Hi all
I'm one of the last optimists who trying to solo mine LTC, but with the last wallet update i'm not able to connect the miner to the wallet.
I'm using windows7 and KNC Titans (bfgminer 5.1.0). My conf file is fine.
Is there anything I can do to fix it except to make my own pool?

Thanks in advance

Any update about it?

I'm still worried how this kind of fork can exist.

So...

Any of "the devs" still alive?

The only non-dead public block explorer for Litecoin's testnet shows the last block as 641435 mined 5 days ago (although the page says "2 days ago").

I'm CPU-mining on that fork with optimum speed that wouldn't rise difficulty from the minimum, which according to my calculations is about 3500 hashes per seconds to stay at difficulty equal to the minimum of 1/4096. I'm currently up to 64196 as of this writing, but I don't see a way to verify that anyone was able to synchronize off of my machines. And they are for sure accessible from outside, both via IPv4 and IPv6. I did receive and mined some transactions earlier today, so some communication does exist, because I don't currently transact on my internal Litecoin testnet nodes, only CPU-mine.

The competing chain seems to be at block 644512 and is getting mined at difficulty 0.00312973
which is ~2.8 times higher than the minimum. While that would be still in the CPU-mining range, I have my test servers in storage and I'm not looking forward into deploying them.

This situation is indeed very worrying, because it clearly shows Litecoin Core client as faulty.

Quoting for future reference:
Any update about it?

I'm still worried how this kind of fork can exist.

Anyone here can post their current experience of synchronizing with the Litecoin's testnet? If possible do both resynchronizing the old install and a fresh resynchronization from scratch as another user on the same hardware and with same software.

Heya,

Today we added Litecoin (LTC) as a payout option on our multipool, www.xpool.ca

We will also soon add so it can also be mined directly.

Cheers!

We now have the direct mining port opened up for exclusive Litecoin mining.

Variable DIFF:

stratum+tcp://mine.xpool.ca:2002 (diff 8 - 8192)

Fixed DIFF (Minimum = 512):

stratum+tcp://mine.xpool.ca:3002 (diff 512)

See here for config setup:

http://www.xpool.ca/configuration_guide

Cheers!

It turns as I was expecting, in other words the problem is back after less than a week:

1) the 0.10.2.2 chain got stuck at block 645801 (which was approximately 14 hours ago) and all further mined blocks don't propagate anymore

2) meanwhile the old chain running 0.8.7.5 an earlier is now at around 645939 and slowly getting further ahead.

3) which confirms my suspicion that there were no real developers looking at the problem and that probably Litecoin developers don't understand the new code their imported from Bitcoin.

So this means that LTC has forked? Sure is not reflected in its price though.

3) which confirms my suspicion that there were no real developers looking at the problem and that probably Litecoin developers don't understand the new code their imported from Bitcoin.


I work on Litecoin Core and know about this testnet issue, I was the one who also made a post advising users to stop mining on 0.8.7.x and upgrade to 0.10.2.2 whilst also setting up a private pool to orphan the version 2 chain. After our notification and to encourage others to begin mining, I lowered my testnet pools mining intensity. In doing so, version 2 blocks got the lead again which lasted in a small fork. If you actually looked at testnet recently, you would see that this issue has now been corrected and my pool settings will permanently stay like this until I see no more 0.8.x miners (subject to availability obviously). The block height is currently at 646208 in which I'm currently connected to over 25 nodes (similar to the dedicated testnet node we have setup), all reflecting this. This can also be verified by a block explorer site like http://blockchains.io/ltct/blocks/

Also, please don't make ridiculous claims that we don't know what we are doing, we know very well what is in Litecoin Core, including the causation of this and we know how to resolve issues like this (as shown above) and is why we contacted all pools to make sure that mainnet encounters a smooth transition for BIP66 activation (which has had 0 problems). Your concern stating that 'if somebody managed to split the testnet that far there maybe a bug lurking in the code that could be used to split the mainnet' is clearly unfounded and shows inadequate knowledge of how this issue occurs. If people could do it on mainnet, they would. BTW, this issue also occurred on Bitcoin's testnet https://blog.blocktrail.com/2015/06/bitcoin-testnet-is-forking-19-blocks-deep-and-counting/, admittedly it isn't a good thing to have happen on testnet, but both Bitcoin and Litecoin devs were extremely focused on mainnet BIP66 activation, as testnet is low priority which can always be reset accordingly if things go haywire (which has been done in the past).
