Topic: Blockchain split of 4 July 2015 - page 5. (Read 45633 times)

Why is this taking so long to resolve?

It actually was resolved pretty fast. (6 blocks ~ 1h)

There was a second incident on July 5th, with a 3-block orphan branch. There are still v2 miners out there, and the v3 miners are still accepting recent block hashes from them, and mining new blocks on top of them before they have time to validate (or even see) those parent. The fork was blotched.

Could you explain this further, I thought bitcoin 10 or above would block v2 blocks from being accepted. So what your saying those blocks are still finding a way on this side of the forked blockchain. Like f2pool i know they fucked up and did something like that but i thought it was isolated event which was fixed. Would this bog bitcoin core down it's been stalling a lot from what miners are saying. I think bitcoin core should be more efficient at blocking those left behind without the extra resources (cpu and ram) to effectively block them.

Please criticize my recollection of what is happening that's the only way i will learn about this in more depth.

Why is this taking so long to resolve?

Surely it is in the mining pools interest to fall into line? Or is there something more sinister going on?

Re stress testing I suppose it needs to be done isnt bitcoin still classed as beta or am I missing the point?

I guess the news at the top of the forum, is just a reminder that you should update your client.
Theoretically this could happen again(I highlty doubt it, since pools/miners already lost money) and the only prevention is to use a up-to-date client(or connect to an up-to-date node)

It is clearly not resolved. Look at the forum header and you will see. Things are not "back to normal" if you have to wait for ~30 confirmation on many clients. This is ongoing as of now until the above warning is removed.

Sorry, for the misinformation. Seems like there was another split according to: https://bitcoin.org/en/alert/2015-07-04-spv-mining
So, miners are stupid enough to still lose money. Sorry, I assumed, they were smarter.

So this happened twice now in a row? Oo

When what is said is correct in this thread then couldnt that be used to attack bitcoin and lower the price of bitcoin? I mean presenting wrong hashes to these pools and letting them create a fork? I guess there is some failsaife built in as to which pools they watch but most probably they watch small ones too and someone could decide that he could earn some coins by shorting them with leverage and then starting the next fork?

Further proof that we aren't ready for mass adoption. Glad I always stuck with Core, but feel really bad for anyone affected by this. 30 confirmations is a ton of time. I hope no one lost money somehow with this if you can lose money in this situation (some transaction getting stuck or something, or being precessed into the other blockchain). This sounds pretty messy to me.

Still. Im impressed that happened 2 times in a couple days. And the first time on the worldwide known independence day in america? Im not into conspiracy theories but the randomness is interesting at least. Nothing for years and then, at this day. Oo

@RealBitcoin
There is no reported double-spend.
From the way, I understand Bitcoin a double spend is still very hard to execute. So, no lemon merchant has the resources to do that.
And yes, I would trust coinbase.

Yes its obvious that its not the merchant is the one that will scam people here. But it was a bit exxagerated in my view, because nothing is affected except trading with strangers.

So if the 99% of the bitcoin users only use trustable companies to trade bitcoin with then nothing happens. Of course when you do an escrow deal or similar with a stranger, then you need to wait that 30 confirm, but other than that, this crisis doesnt look serious at all.

I hope that the current core client is stable, i`ll wait a few more weeks until i upgrade

Ok but this only is concerning to p2p transactions isnt it?

I mean if i get bitcoins from a trusted source, then what does it matter if they have 3 confirm or 30 confirm. For example if i buy bitcoin from coinbase, then obviously then wont double spend me neither with 2 confirm nor with 10 or 30 confirm.

This is only if i am doing business with a stranger right? So if i trade face to face with a stranger on the streets, for example 1 kilogram of lemons in exchange for 0.05 BTC, then if i go away after 10 confirm, he can still double-cross me and double spend the TX.

So i guess this entire "crisis" is only concerning to face-2-face trading and transactions, but not if you get your coins from trusted source right?

Ah right thanks for the info, I just presumed as it was on the forum and still mentioned at Redit that it was ongoing Grin

Could you give me a link to Reddit, where people claiming, that it is still ongoing(I am hardly ever on Reddit, I don't even have an account there)?
Maybe I am missing something.
