So do this new chain is still compatible with old lky wallets and tokens ? Did someone try already ?

Hello there.
Would like to ask a few questions.
How were you mining Lucky before this new fork was introduced?
Up to what block height was it running?

[lkyinvestor]

from the block 81,743 (Nov25, 2013)? lky was pumped on cryptsy in November 2013 and sold to many accounts in 2013-2014, and now forking from the point before that, hidden double spend with 11 year gap

Luckycoin was traded on exchanges and mined not only in 2013, but also in 2014-2016 and later, at least till Feb 28, 2019 (till the block 1,581,108):

hey there, thanks for sharing
curious on this double spend that happened before.

are you saying that this double spend was still included in this new fork of LKY that is running right now?

Hi

When someone revives a coin, it is obvious that you have to revive it from the last block of the longest chain,
to include all transactions - that guarantees all funds are safe, all is fair.

In case with LKY, "revival" made a hard fork from the block deep in the past (found on Nov, 25, 2013), 11 years ago.
After this block there is a gap to August 2024. All coins accumulated since Nov, 25, 2013 till August 2024 are not present in the new chain.

Then it is a question why that was made in a so strange way, with so much evil for many holders.
Why just not revive from the latest block with all those transactions happened since Nov, 25, 2013 included?

One who made a "revival" probably owned LKY in Nov, 2013 and then sent coins to Cryptsy exchange wallet when there was a famous pump called "Remember the moon in November".
Then sold LKY on Cryptsy to investors who were buying Luckycoin. So, investors paid their BTC and got LKY after Nov, 25, 2013 - on Cryptsy platform and then sent LKY from Cryptsy to their wallets - after Nov, 25, 2013.

But if you restart the project from the block found on Nov, 25, 2013, when coins were present in the wallet of one who sold them on Cryptsy later, the person again owns the coins which were sold many years ago, and is able to double spend them now.
While investors, who bought coins many years ago, don't have them any longer, because these transactions are not present in the new chain.
That looks like a new, uncommon type of double spend, with 11 year gap, hidden under "revival" idea.

That is just a logical explanation of why the block in the deep past was chosen to "revive" the project.
Even if it is not exactly what happened, anyway investors were buying LKY in 2014 and later, now their holdings are not present in the chain, and new investors are buying the same concept.
So, in any case it looks like double selling of one concept (under one name, logo, story) - because previous buyers automatically lost their share in LKY project.

Understood. This explains a lot.
So rolling back the chain to a much earlier state allows someone who still has access to these old wallets to spend them now in the new fork.
Completely negating any newer transactions that were done before.

Which probably explains why these so called "dormant" wallets has become active again.
I made a post about it recently on X.
https://x.com/ZachZwei/status/1872301134813237399
The scary thing is, this unknown user seems to have access to multiple wallets.
Distributed some old coins to new addresses.
The LKY revivers seems to promote that it was the og dev "LuckyC" is in control of this wallets.
What do you think?

Also, I was experimenting with the og LKY client v1.0.1 and saw a bootstrap.dat file which was still downloadable.
Ran the clien with it, and it is syncing way past this so called "revival".
Currently at  block 537269, dated March 19, 2015.

Posted about it too to highlight the fact that the og chain is still downloadable and syncing.

LuckyC created LKY and left it shortly after pump-and-dump was finished, not caring about the fact that the first wallet had critical security issues: https://asktom.cf/index.php?topic=214614.msg2540519#msg2540519

Luckycoin security update was made by Titan (one who created this ANN thread):

Titan was in charge for several versions of wallets, for ACP (advanced check pointing system, preventing 51% attacks) which was implemented in November, 2013,
additionally for OpenSSL heartbleed fix in v1.0.1:
https://asktom.cf/index.php?topic=214614.msg6163819#msg6163819

The latest stable version 1.0.1 was in use since 2014 and the wallet has been working flawlessly for many years:

Thanks for the summary.
So, with regards to this information, the original creator did not even care to manage the client properly, just left immediately.
Titan contributed more in further development of the project.

Curious on who is in control of these old wallets that has been recently activated.
And is actively moving coins across multiple wallets.
They probably planning to do something...
https://x.com/ZachZwei/status/1873216900295213253

I highly doubt it is LuckyC.

[melander81]

I was able to completely sync my node to v1.0.1 and start mining original Luckycoin.
It still works.
The restart was a sham.
Only made to benefit the early miners and double spend old coins.

What block number are you up to?

Anybody can do what you did. You can take an old version of Bitcoin, fire it up & be the only miner on the network. Same thing for hundreds of altcoins.

Before I turned off my miner, this was the current block:
{
"blocks" : 1606178,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00094703,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 28309,
"networkhashps" : 127075,
"pooledtx" : 0,
"testnet" : false
}

It was dormant since 2022.
There are other miners testing it now as well.
All details are on my post on X.


If anyone can do it, why didn't the "revival" do the same thing I did and decide to prune the block data to start at 81k instead?

Well, you don't need to answer; you probably wouldn't know the reason.

You blocked me on X, so I'm going to just take your word for it. Frankly yes if I was reviving a coin, that's how I would have gone about it (not sure this is what you did but): find the longest possible version of the chain and use the old wallet client. This does lead to inherent problems but is the closest technical way to revive a coin.

How do you know they pruned the block data?

[lkyinvestor]

Luckycoin is listed on the reputable block explorer service:

https://chainz.cryptoid.info/lky

Their block explorer is on the longest LKY chain, historical, original one.

If you are interested, please contribute and pay several $ for hosting.

oh wow, so my efforts in doing the revival can actually be tracked in real time.
let me look into this and see what we can do
technically, the chain has been running smoothly
the miners have actually spiked the hash rate to almost 2500% since last night.

still trying to deploy my own seed node to keep the chain running as much as possible
thanks for sharing.

[melander81]

I am not sure what is going on.

I checked the address, L3XnfLo5m3BrZxH5PVxxpg38G8F8X7oDfd on the old explorer.
Saw this transaction:
https://chainz.cryptoid.info/lky/block.dws?731493.htm
Happened on block 731493 dated 9/5/2015, 6:56:09 AM (UTC+8:00).

It is literally the same as the new transaction on the revival.
https://luckyscan.org/tx/011960b7cf1f347f5ea161da55e3d0e8d7a6ed742efeb9bf5f5c877f90eded1c
Happened on block 238007 of fork lucky, dated ‎2024-12-26 19:58:12 (4 days ago).

But they are both completely different block height.
WTF

edit:
my theory on this
https://x.com/ZachZwei/status/1873565914408571048

[lkyinvestor]

Transactions differ, some inputs are the same
because they occured in July, 2013, before the fork point (November, 2013).
That means they belong to the part of chain from 2013 which is the same for both chains.

https://chainz.cryptoid.info/lky/address.dws?L3XnfLo5m3BrZxH5PVxxpg38G8F8X7oDfd.htm
Here we can see that coins were received in 2013 and spent completely in 2015, but on a new chain which doesn't include blocks from 2015 - they could be spent again and that happened (with same inputs from July, 2013).

According to some sources, it looks like it was something called a "replay attack".
The transactions I mentioned above are just some of the few tx that has been recreated.
It does not need any interaction from the original owner of the address.

Any transactions on these old wallets that occurred later after that block can be replicated on the new chain.
As long as certain conditions are met, like balances and destination addresses.
The entire integrity of this "revival" Luckycoin is now compromised.
What a mess.

According to some sources, it looks like it was something called a "replay attack".

Not necessarily. It could be someone consolidating coins in their own wallet for a second time. A "replay attack" would carry some serious speculation, including that the recipient of the funds would have kept their wallet and private key for 10 years.

Seems like a standard hazard in such an undertaking. You're assuming that the "attacker" would somehow have access to recipient addresses, because they of course can't be recreated. BTW you missed my last question:
