Hi your mine about bicoin core is about program ? or website ? i always use of website and have good job
did the problem keeps ? i saw several reply but no one said yet that is all ok,soo fake transactions sounds a bad way hope blockhains just fix those mistake
I think the answer is that that is written in the news of this forum:
"If you are using any wallet other than Bitcoin Core 0.10.x or 0.9.5, then you should not trust incoming transactions until they have ~30 confirmations."
Ok so for example i got an older bitcoin core version, way before the header stuff was included. So if i download the latest version, do i have to redownload the blockchain too? Because the blocks got corrupted?
Also i use blockchain.info as a secondary online wallet, do i have to worry when i send or when i receive bitcoins?
If you run the latest core version you're fine.
as for blockchain.info - they did not even identify this issue (read up in this thread) - so it's not save to use them at the moment.

This seems to be only a minor problem for now. The problem will get updated and it should be fixed fairly quickly.

Read the previous posts in this thread. You will find an answer.
OMG WTF guys? I`m getting scared.
So if i just send now a transaction, then i lose my bitcoins and it doesnt get to the other end?
Also what if i buy now bitcoin with € do i get fake bitcoin if the merchant is on wrong chain?
This could be a serious problem. No FUD intended but seriously, i`m starting to panic/

OMG WTF please read carefully before getting panic. Everything is settled, those who using Bitcoin core older than 0.10 and was receiving payment during fork period should wait at least 30 confirmations.

Just relax. Why would you panic at all? Obviously you're that kind of person, so how about you just pause everything related to Bitcoin for a day or two?So if i just send now a transaction, then i lose my bitcoins and it doesnt get to the other end?

You don't buy Bitcoin from merchants, but rather on exchanges. Even if something does go wrong I'm pretty sure that Bitstamp would reimburse you.
We just need someone to confirm this. I think that everything is fine now, however I can't be sure.

So, I was AFK and only noticed this now... Sent 2 transactions from an SPV wallet 2 hours ago, I hope they confirm normally. At least the forking issue seems to be no more...
And there we have it, folks SPV mining. Amazing
I hope everyone starts taking this seriously and start validating blocks. It's of everyone's best interest to keep the blockchain healthy. I thought miners were aware of that, but apparently not. Quickly relaying blocks isn't going to give them profit, validating blocks and keeping the blockchain running smoothly is, I hope they learned it this time.

There were 2 major chains (1 was legit, the other one wasn't by Chinese miners).
For now "miners" integrated into Main chain, But what would happen if they insisted on their chain?
You have to differ between miners and pools. If pools would go rough, the miners would most probably go to another pool. Miners would suffer the most from such a blockchain war, since they have all this expensive hardware, which is worthless without Bitcoin.There were 2 major chains (1 was legit, the other one wasn't by Chinese miners).

It does sound quite a worrying situation that some pools can so easily and accidently go rogue and basically make all transactions questionable.
Imagine if they or someone else decided to try to mess up the network, 30 confirmations is a very long time to wait.
I have updated my qt and will wait a while before using electrum, I won't be spending any BTC until this evening anyway.
glad i use the latest version of bitcoin core, not sure why people still use older versions as it doesn't require more than 1 minute to update the wallet.

Can someone explain why 0.9 bitcoind are not safe to use ? Won't they also catch up to the longest chain later ?
They allow invalid blocks.So, if you have 2 chains one with invalid blocks and one without. Bitcoin Core 0.9 would chose the longest block as the right one. Bitcoin Core 0.10.2 would just ignore the chain with the invalid blocks.
Bitcoin always choses blockchain with the most work done (sum of all hashes that were used to create blocks, since genesis block) which is not neccessarily the longest blockchain.
Bitcoin chooses the valid blockchain, with the most work in it. Huge difference.
Just saw the warning. Glad I did. I use Electrum for my hot wallet. (Not that I keep much in it anyway)
Is there any news on this? I've looked through the end of the thread -- this is where the warning points -- and it appears unresolved. Am I crazy or shouldn't this be an easy fix for these pools?

electrum uses nodes. go to console and check the status "This node is running bitcoind 0.10.0 with no scheduled restarts." < means you're good to go
Which is command for status check?
on the last tab (console) some of the nodes mention what version of bitcoind they are using. i think that is enough.
EDIT:
for example this one: "erbium1.sytes.net" says "bitcoind 0.10.0 (full node)"

If PEOPLE use Bitcoin Core 0.10.2 or 0.11.0 RC3, they don't have problem.
On bottom, the complet LOG of the blockversion error (v2) ... and the correction of the network (bitcoin !) after this (v3) with 12 blocks in row to invalidate the v2 ORPHAN blocks.
No problem here, the blockchain is true ... and Bitcoin Core do the job.

Can someone explain why 0.9 bitcoind are not safe to use ? Won't they also catch up to the longest chain later ?
They allow invalid blocks.So, if you have 2 chains one with invalid blocks and one without. Bitcoin Core 0.9 would chose the longest block as the right one. Bitcoin Core 0.10.2 would just ignore the chain with the invalid blocks.
Anyone on SPV wallet question?
ARE SPV wallets (i.e. Multibit) safe?

Using anything other than official Bitcoin-Qt wallet (full node) is playing with fire. For the sake of saving 40GB of HDD space and to have a bit faster syncing you have massively increased a chance for all sort of troubles and you are actualy not contributing to network at all, just draining resources off of it and using up others' connection slots. As far as I know, SPV wallets are not relaying transactions or blocks, they are just like people on Torrent who download stuff but not share anything.
SPV wallets were Satoshi's idea. He knew they would be needed by people with low spec computers and metered internet connections. People have complained the Bitcoin core wallet can take a week to sync on a low power computer with a slow connection. They say if anything goes wrong whole it's syncing and the database gets corrupted you have to start the whole process again. My computer is too low power and has too little free memory to consider using the Bitcoin core wallet.
Not everyone has the choice to use the Bitcoin core wallet, some people have no option but to use SPV wallets.
"Here I have 100,000 USD and I'll put them at insecure and problematic bank because I have no money for better one".
Not everybody has 100'000 USD on its wallet (I wish I had, though). Especially if you want to have some petty money on the laptop, mobile or tablet, SPV wallets are pretty handy. I, for example, have one mobile phone which I use about five times a year. SPV is best for it...
Well, this whole thread and many others are proof SPV wallets suck balls.

There have been attempts to get the unbanked in third world countries to use Bitcoin. they would be lucky if they could afford the most basic Android phone there is. SPV wallets are the only option for them. You cannot tell them they should only use Bitcoin core because they probably don't own computers. What we might consider petty money on a mobile phone might be a lot of money to them.
I absolutely agree. I run a couple of core wallets and a node,, though, but I just have to look at my family and see that they want - and need - a quicker solution which makes it easy for them. Here we are again discussing mass adaption...
