News: Due to BIP91, it would starting now be prudent to require 5 times more confirmations than usual before trusting transactions.

Have you redownloaded the entire blockchain from scratch (i.e. deleted the blocks folder in the datadir or used a completely new datadir)? If not, try doing that.

Otherwise, you may have a hardware issue, not necessarily disk. More likely you have a problem with your RAM. Just run system diagnostics and see if it finds anything wrong with your system.

3  Bitcoin / Development & Technical Discussion / Re: 1hash pool just mined an invalid block again on: Today at 06:21:11 PM
For what I can see the transaction is there, but is placed later in the block.
Yes, see my update Wink

I believe 474294 had a similar problem, because I think I was checking it back them when in happened.
474294 is missing the parent entirely.
4  Bitcoin / Development & Technical Discussion / Re: 1hash pool just mined an invalid block again on: Today at 05:56:43 PM
Both blocks are invalid because they included a transaction without including its unconfirmed parent.

I checked block 474294 and it contained transaction a6655ca47c62ffcbf6d3dcba34bc1af24a1eb0bcea54d3099d36201a66aec2a0 but not its parent transaction b11a78c6c61af1cb37586f639050d74b95c2b0fd525623b6cb6a4bb4fba46a0e.

I'm still checking block 477115 for which transaction it is missing, but it triggered the same error message as 474294, so I believe it is caused by the same problem.

Update: Block 477115 is actually more interesting than 474294. It contains the transaction 7a122ef22468e4af16b010d7acf7aa81e5af3636423c613fd98246c179d79800 which is missing its parent 9639dd073e67efc879abb1075fafa4fa23d5fa427c129b2b1dd4f5a5520b408d. But the interesting part is that the parent transaction is actually lower down in the block. So the problem here is that the transactions are in the wrong order, which means that they are probably permuting the order of their transactions.

One thing to notice is that 477115 contains 256 transactions and 474294 contains 255 transactions, both of which are good numbers of transactions to have for asicboost. Furthermore, this problem could be caused by permuting transactions as would need to be done for asicboost.

Edit: corrected transaction counts
5  Bitcoin / Development & Technical Discussion / Re: Understanding split of the coins in a hardfork on: Today at 05:46:34 PM
People are speculating about the up and coming Bitcoin Cash, also known as Bitcoin ABC (are they the same thing? I think they are).
Bitcoin ABC and "Bitcoin Cash" are the same thing.

Let's call this BCC.
Lets call it Bitcoin ABC.

This is considered a hardfork right?

Anyway so from what I've understood, when a fork happens, if you own the private keys, you will receive exactly the same amount of coins in your wallet, on the other chain.  This is why it's very important that you must own the coins by the time the fork day happens, or else you will be at the mercy of exchanges listing or not the forked token.
You won't be receiving any coins on the other chain. What you will have is a wallet which has exactly the same state (same transactions) as your wallet on the other chain.

My question is: If im keeping my coins in Bitcoin Core, how do I access the Bitcoin Cash tokens?
You can't. Bitcoin Core cannot understand the consensus rules that Bitcoin ABC will be deploying. It is a hard fork, so whoever wants to use that fork needs to upgrade their software. The only way you can spend Bitcoin ABC coins is to use the Bitcoin ABC client.

I have tried to find an answer and im confused. Some claim that the wallet.dat files will be compatible with the Bitcoin Cash full node, so you open it there and it will work. I think this will not work.
Because the Bitcoin ABC client is based off of Bitcoin Core, you can simply copy the wallet.dat file into a data directory you are using for Bitcoin ABC and be able to use your wallet from there. They are not incompatible.

If so, how does it work in detail? I want to be able to dump these damn BCC tokens to get some free BTC.
Just copy your wallet.dat file into a data directory that you are using for Bitcoin ABC. Then you will need to split your coins. You can read about how to split your coins here:
6  Bitcoin / Development & Technical Discussion / Re: If Segwit2x gains 90% support before Aug 1st, will BIP148 still go live? on: Today at 05:41:25 PM
Thanks for enlighten me.
Which sites - Where could I find such charts about miners signaling various proposals?
That chart was from You can also check out and

I always thought it is the same but it turns out just a half of segwit2x.
Since BIP91 to activate segwit require all blocks signal for segwit, all blocks? So, if some of miners are spy mining or a pool stop enforcing bip91, then segwit2x won't be activated?
Segwit2x is not one thing that is activated, it is several things that must be activated sequentially.

If some miners are spy mining or they stop enforcing BIP 91, then segwit may not be able to activate, and segwit2x will not continue with its plan.

It's make me confuse about how to activate segwit2x? All blocks should signaling for it?
Segwit2x will continue when segwit becomes active. According to BIP 91, all blocks must signal for segwit. That way segwit can become locked in in its next signaling period, and then activate one signaling period after it becomes locked in.

how much data should I expect to be used on a monthly basis?
Normal node operation is another 3-400 GB of data
That's per month data. Roughly. If your node is up for a long time, then you will be consuming more data as more nodes connect to yours.

Is the date of August 1st still an important date at which we should stop trading bitcoin, or with BIP91 locked in did anything change?
August 1st no longer matters. BIP 91 locking in changes everything. Now what matters is that miners must actually enforce the rules that they activated. The new rules (all blocks must signal for segwit) will activate tonight, so that means that from that point forward, we could potentially have a forking event. This will be mitigated if people start running software that enforces the BIP 91 rules, but there are very few nodes that are.

I have money on coinbase and want to buy in a dip but can't say for sure if i'm in any kind of a risk buying after BIP91 locks in (which is tommorow) or after 1st of August now that BIP91 will be locked in earlier?
The risk begins after BIP 91 activates.

No. Do not do that. Please stop spamming that nonsense. Bitcoin Core 0.9.1 will likely not be able to sync with the network anyways. It has known performance and security issues. Furthermore, you will not be fully validating all active network rules.

Since you have a hardware wallet, you are fine. You control the private keys. You can use your ledger with a desktop wallet software like Electrum in order to make sure that you are using the chain that you want to use. Splitting your coins is harder to do, but you can do it with Electrum. There are instructions for splitting your coins with Electrum here (albeit for BU, not a BIP 91 or BIP 148 split, but instructions still apply):
11  Bitcoin / Technical Support / Re: Data Consumption on: July 22, 2017, 04:52:58 PM
You will need to sync the entire blockchain, which is ~120 GB now. You will be downloading the entire thing when you sync. Normal node operation is another 3-400 GB of data as you may be providing the blockchain to another node and you will be downloading and uploading all blocks and transactions to many different nodes. If you are unable to support that much data transfer, read the instructions here: to lower your data usage.

14  Bitcoin / Bitcoin Discussion / Re: About the "Unknown block versions being mined!" warning on: July 22, 2017, 04:29:36 PM
Ok, We have BIP91 locked in.

The message of the Core shouldn't be dangeous.
But my Core wallet is not working well. The syncro works fine. But when send a payment there is no connection, and the movement is not broadcasting to the network.

What I'm doing wrong? I was thinking that Core users donīt need to change anything (using 0.14.2)

But Why I cannot send funds with bitcoin qt wallet?
It has nothing to do with the warning or any potential forks. You have likely just done something wrong. Make a post in the Tech Support forum and people will help you there. Don't ask for help in this thread as it is off topic.

I heard somewhere else it's 10mb, can you show me the code?
You have heard completely incorrectly. In Bitcoin Core, the maximum size a serialized block can be is 4 MB: In btc1 (segwit2x), it's 8 MB:

Isn't Bitcoin science? If it is science you should do prediction the future So could you explain at what conditions the hard fork is inevitable? and how much is the probable of getting those conditions at future?
Sure, its a science, but it also includes randomness. There is randomness and several unknown variables that make an accurate prediction hard to do. We don't know what percentage of miners are spy mining; we don't know what percentage will actually be enforcing BIP 91. Then you also have to factor in the human factors too like will a pool start or stop enforcing BIP 91 based on what they see happens to a BIP 91 invalid block? Or will a pool which currently isn't signaling start signaling before or after activation. Then there's other things like how much will the hashrate grow? Since there are so many things that you need to know in order to predict anything related to forks, making a prediction is hard to do without assuming many of those things, and those assumptions can be completely wrong thus making the prediction completely wrong.

Your question is nearly incomprehensible. Can you please try using non-broken English or ask in the proper local sub forum?

If not build segsignal patch of Bitcoin Core. Will be work Blockchain node?
If by "blockchain node" you mean full node, yes, it is a full node.

How to find out what patch need build?
Look at my earlier post. I linked it to you.

or bitcoind will be show "getinfo": Error { need build and install path...}
This doesn't make any sense.
19  Other / Beginners & Help / Re: [Guide] Handling splits: UASFs, BIP148, etc. on: July 22, 2017, 06:26:02 AM
So, now BIP 91 is locked in.
Does it meant that all danger (about split) is already behind?
No. There is still potential for a split with BIP 91 as many miners may be false signaling or spy mining thus end up mining a BIP 91 invalid fork. This would be reorged out later once they notice/the other side of the fork catches up and becomes longer. The likelihood of a persistent chain split is low, but there may be many non-persistent forks.
20  Bitcoin / Technical Support / Re: unconfirmed pending bitcoin transaction.. 24 hours? on: July 22, 2017, 05:42:29 AM
Your transaction has hundreds of confirmations now; you are fine. If the service you are depositing at does not show that, then they are wrong and you should contact their support.

There is nothing you need to do to get more confirmations; the hard part is getting the first confirmation as that means getting your transaction included in a block. More confirmations come later as new blocks are found which build on top of the block that your transaction was confirmed in.
