Topic: Ixcoin TODO - page 108. (Read 631747 times)

All iXcoins have been minted and the blockchain is solid and running smoothly.

Experiment has been successful.

Now, time for the next phase.

@publicjud - Ya that is how I see it too, looks to me like the blockchain is holding up really well!

Was wanting to ask anyone running the ixcoin client, please go to your console and do 'getblockhash 227500', then 'getblock ', if it shows a 25.something coin spend tx in there, shut down the node and let me know.  Not sure if this was widespread or a targeted attack, I would have been the only one showing up on the network with a client version of 090300 last night...


@Vlad - Actually I think I do know where some, if not all those 94 coins are at, it's kinda a long story, but not a serious problem.  Think you, cinnamon_carter and ahmed have all heard about it, will try to give the short version here for everybody.  Back in Sept I found & coded a solution to some blockchain damage.  Analyzed the problem in great detail, weekend before last.  Finally added my notes to the comments section of the source code that I'm committing to GitHub today.  All the latest 0.9.x client releases know about what happened back in April 25-26th, 2013 to the Ixcoin blockchain, a miner was creating duplicate tx values, until today I thought it was just software gone wacko, now I'm not so sure, we have 4 Tx dup hashes that effected 13 blocks, so 8 are found as duplicates, that would acccout for some missing coins.  We were mining 96 coins/block back then, so I would expect it to be more than 94, looked to me like the miner screwed himself out of some of the rewards though, as the coinbase Tx outputs were spent soon after it happened.  Actually it's because the new 0.9.2.1+ software is so superior that I was able to find it, with the 'verifychain' command set to level 3 or above your local copy of the blockchain is ripped apart, one block @ a time, backwards in time, with calls to DisconnectBlock() all the way back to the genesis block, if you set the num of blocks to 0.  Its a really good test for your copy of the blockchain, level 4 is even better as it then reconnects all the blocks forward in time to the present.  All the details and the fix are now coded into the source, bitcoin has had similar such problems as well in the past, it is though, one of the reasons I want to get everybody upgraded to newer software as soon as possible.

A massive risk has been removed. With stocks there's an immediate increase in valuation when that happens.


As for Zebedee....time to suck it up and admit I was right and you were dead wrong.  haha!

Where's my tip?  lol

Thats actually a good sign.  Someone actually sees IXC as a threat, and it also is a good test to see how the blockchain holds up under attack.

So today is not the Doomsday, heheh.

Now patience

Thanks a lot Groundrod.

Can you tell us why we're 94 coins short of 21 million?

As for this attack, it can't be CEX cause they would have succeeded.

But it has to be someone with a massive mining operation cause he thought he might actually succeed.

Does anyone come to mind?  lol.

I know who you are Zebedee.  Nice try.  haha.

On my 1st cup of joe & started out by looking at my debug log, just happen to get up before block 227500 was created to find all the peers on 227499, then saw zebedee toasting champagne and deadsea33's 'Thats all folks', thought oh shit we have a problem, now see the network is still humming along ok too, working on block 227506 here.

Still trying to figure this out, so bare with me, looks like we have an attempted attack by the same miner address that messed with Ixc back in April 2013, I recognize the receiving address, an attempt is being made now for block 227500, a 25.09 coin spend has shown up in my copy of the blockchain, according to http://darkgamex.ch:2751/chain/IXCoin the attach failed as they are showing the block as having  0 total value.  In any case, I'll not be building a new bootstrap.dat file just yet, with this copy of the chain, until I've reloaded at some non-disclosed point in the future, after many confirmations on all the blocks that I build into the new bootstrap.dat file.  Sorry asshole you will have failed.  

So wanted to let everyone know that I'm checking things really close & otherwise things are looking super!  All the new blocks so far have a coinbase of 0 and total value of 0, block 227505 just showed up with some transactions, and creation seems to be humming along nicely, even with the above issue discovered.

GR

Value out 0, 0, 0.

Bhwahahaaaaa.

It works!!!

Zebedee, time to eat your crow.


The blockchain is working great with 0 output.

Now it's time to awaken the Kraken [Jeffrey Smith].

It's all cool Vlad.  Blockchain is at 227502

100,000 left?  Wat?

There's like 74 coins left but the blockchain appears to be stuck.

It can't seem to mine those last 74 coins.

What's going on?

Bummer for you, it just made a zero out block...  NO surprises here.

Looks like buyers are hoping for a panic sell.  lining up sub 9000 sat on Cex.io

Time will tell..   And not much time at that.

FYI, there have been smaller coins that ended PoW without issue..
I realize you hung your reputation on IXC failing so I'm sure you hope the chain locks up!  And Vlad hung reputation on IXC sky rocketing. 


430 IXC to go....

And I will just note the fact that no-one has considered the technicals of this by replying to my question of "can the software handle empty blocks?".

Because none of you have a fucking clue.

Just 16 blocks left!  I'm already on the champagne.   

I've not made any accusations.  I may have a made a prediction that it's the end, and I do believe that any straight-thinking person must see that.  This coin is stunningly insecure, because once any one of the 2 or 3 big miners supporting it no longer see a reason to continue (quite understandable when their income is zero) the hashrate will drop so much that blocks confirmation time will become high / infinite.  See ATC for example.

By the way, I expect a big increase in the volume. x10 won't surprise me (from around 20.000 IXCs yesterday on CEX).
