So what should the current block be?

This is the chain I'm on


{
"blocks" : 68026,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00024414,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 708553,
"pooledtx" : 0,
"testnet" : false
}

If you like my post please feel free to give me some positive rep https://bitcointalk.org/index.php?action=trust;u=18639

After block 64k, difficulty dropped and no increase of difficulty since then. Looks like there is some bug in the new version.

No as I pointed out there was a fast block injection well before block 64k, I assume an attack as there was no payout address on the mined blocks. You can see after block 64k that most of the blocks were still paying out 1,000 coins meaning is was an old or hacked client.

I would say that block 63485 onward was a forked chain and we need another checkpoint release if it doesn't correct itself. I certainly wouldn't be doing any transactions.

No, block reward after 64k block is 400 in all cases. Last block I received 1000 GME was before 64k.

correct it was near that point where my pool with the majority hashpower switched off the network onto its own fork since i wasnt around to update, so technically we are now on what we would like to call the proper chain

an official announcement on the 2GMTA-Website says: all block explorers of the 2GMTA pools are disabled currently due to instability

therefore the block-chain you pointed to maybe not correct....

Btw, I'm obviously not the only one mining this chain. Only 1 out of the 10 blocks is mine

This is not the blockchain I was talking about.



I was talking about this blockchain. After 64k block on this chain, the block reward was 400. The blockchain you provided has all blocks after 64k with reward 1000.


15:01:02

{
"blocks" : 78936,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00024414,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 777111,
"pooledtx" : 0,
"testnet" : false
}

Or "this" blockchain:

Everyone should really stop mining and allow me time to look into it. There is clearly something wrong with the code in v0.8.3.1 which caused the difficulty to just continue dropping until it hit the absolute minimum regardless of the amount of hashing power that was thrown at it.

One thing is for sure I'm going to have to roll back the code to the state it was in v0.8.2.1 at the very minimum which means that anything mined from block 64,000 onwards with v0.8.3.1 will become an orphaned block. At least the difficulty is actually increasing on the v0.8.2.1 fork.

good call. 10000+ blocks or 15-20% of the whole blockchain mined in a few days is not healthy

Even worse  Grin

Sucks for the few who've been mining on the correct chain, but reversing to block 64000 is needed if we ever want to see this coin traded again.

right okay. my pool is currently up to block 61.5k after a lot of manual labour when we hit 64k i shall kill the pool for everything apart from withdrawals. I will have another pool up for GME soon which will be prop until the fork issues are solved and then back to PPS, expect a nice pump to the prices too since ill have to buy up quite a lot for PPS

The point everyone seems to miss is the problem started at block 63485 not block 64000, prior to block 63485 blocks were being found every couple of minutes, then they suddenly were coming in every few seconds, I was watching the count on one of the pools stats pages, not on the block explorer that came later. Someone started to inject fast blocks at block 63485. Then when we hit 64k some of the blocks were 400 coins long but most were still 1000 coins. I would say the 400 coin long blocks were the legit ones, and the 1,000 were an attack or bad cleint.


A fundamental flaw in all the crypto coins bases on Bitcoin code, is the ability to accept mined blocks at a faster rate than a per-determined lower limit. eg. if you want your block rate to be 60sec then peers should not accept blocks that are time stamped ad being mined less than 30sec apart. The client software should use the  many time servers on the Internet to set the time accurately, then reject impossible time stamps such as pre-mined chains from an attacker.

IRC peers should be disabled by default in the client software, and a few reliable seed nodes in the code.

I good coin should use NTP timestamps not timestamps agreed by the coin network. The problem is discussed here:
