761  Bitcoin / Wallet software / Re: Created TREZOR address with Ledger nano S ...problem on: January 15, 2018, 06:11:30 PM
What do you mean by "created trezor address with ledger nano s"? Do you mean you imported your trezor seed onto the ledger? Or do you mean something else? How did you do this?
762  Bitcoin / Development & Technical Discussion / Re: lost funds for multisig on regtest on: January 15, 2018, 06:07:36 PM
createmultisig does not add the address to your wallet. So the multisig address is not part of your wallet and thus not listed in listunspent.

To add it to your wallet, you need to use addmultisigaddress.

What do you mean by "making electrum/core segwit compliant"? Do you mean how to make a segwit wallet with these software?
764  Bitcoin / Bitcoin Technical Support / Re: BitcoinCore node crashing on: January 15, 2018, 06:00:31 PM
I'm only guessing, but so far the only thing I can think of is when I tried to hook up the 21 ras pi that is where the driver power state failure happened and the blue screen from that event is what might have? caused the corruption of the files or just the wallet data?
If you pulled the power from the raspi and then took the wallet file off of it afterwards, that could have caused it to become corrupted as the database is still open and there are other files that you need when the wallet database is still open.

Have you tried just powering on the raspi again and seeing if you can access the wallet there?

double clicked to launch, starts to open then closes with message saying missing .dll file.
What .dll file does it say is missing?
766  Bitcoin / Bitcoin Technical Support / Re: Database corrupt on re-start [Was: Bitcoin-qt cannot read the database, closing] on: January 15, 2018, 05:52:28 PM
I was hoping that some developer would want to work on failure modes.  Look for root causes of bugs.  But nobody seems interested. 
The root causes are usually out of our hands. In many cases it is hardware failure. Bitcoin Core does a lot of disk I/O and uses quite a bit of memory and processing power. So often times hardware issues (typically in memory issues or disk issues) are the root cause of such problems. I suggest that you run some hardware diagnostics on your machine and see if anything turns up.
767  Bitcoin / Development & Technical Discussion / Re: How can i read Block.dat Files without using full node from C# on: January 15, 2018, 05:45:44 PM
The data in these "Block.dat" files is not raw text anymore
It never was in the first place.

but it seems like i need to read the files using
Berkeley-DB format which does not compile for me so does anyone know where I can download a Berkeley-DB Dll that
will work in VS .Net or any short cuts using .NET file streams
I think Berkeley-DB for the file format has been dumped and they now use LevelDB that is something
that Google started but getting a copy that will compile and works in MS-Dot.Net is no easy task
The blk*.dat and rev*.dat files - the files that actually contain the block data - are not database files. They are just files with the raw blocks dumped into them. You don't need BDB or LevelDB in order to read them. Those databases are stored separately.

The format of the blk*.dat files is network magic (4 bytes) followed by length of the block in bytes (4 byte unsigned integer) followed by the block itself serialized in network format. This repeats until the file reaches a certain size. Then the next numbered file is used.

Any timeframe when the site will be able to return to work or if it is final?
Consider it down forever.

Do I need to install python to run achow101's?
No, unless you want to use it from source. There are binaries available here: https://github.com/achow101/payment-proto-interface/releases/tag/v1.0.1

At this point, if I were to just save the wallet dat. file and completely uninstall and reinstall bitcoincore, is there any possibility that I will run into any problems with creating my wallet from the seed/passphrase?
That won't work.

Firstly, the problem is with your wallet.dat file, not with your installation of Bitcoin Core, so reisntalling isn't going to change anything. None of Bitcoin Core's data is removed when it is uninstalled, only the exectables are.

Secondly, Bitcoin Core does not use a seed or passphrase which can restore your wallet from scratch. You must have a backup of your wallet file.
772  Bitcoin / Development & Technical Discussion / Re: Raw original work request of solved block on: January 13, 2018, 05:00:50 AM
Ok so if I'm getting what you are saying is, once the block is solved below markel_root becomes a transaction id to send newly generated coins which is already included in blocexplorer's transactions

merkle_root = sha256(sha256(unhexlify(coinbase)).digest()).digest()
No, not at all.

The coinbase transaction's txid is included as part of the merkle root. The construction of the merkle root is described here: https://github.com/bitcoin/bitcoin/blob/master/src/consensus/merkle.cpp#L9. Basically you concatenate the txids of pairs of transactions and hash them, then concatenate pairs of hashes, and so on until there is only one hash remaining.

The fields Coinbase1, ExtraNonce, ExtraNonce2, and Coinbase2 are used to construct the coinbase transaction which pays the miner. The transaction id of that coinbase transaction is then used to construct the merkle root.
773  Bitcoin / Bitcoin Technical Support / Re: Bitcoin transaction "sending" since december 18.. on: January 13, 2018, 04:05:00 AM
No because I haven't recieved yet as I sent it back to my original bank I originally deposited the money from. When I click on transactions it says in red "sending", and when i click on the transaction itself it says "status": confirmed below where it says the date.
Then that is a service problem with the service not crediting your Bitcoin. The transaction is confirmed, that means it is completely and absolutely final. Contact the customer support of the service you are trying to send money to.
774  Bitcoin / Bitcoin Technical Support / Re: Bitcoin transaction "sending" since december 18.. on: January 13, 2018, 03:50:36 AM
It's in block 500010 it says. I use Blockhchain. Other info when I click on the transaction: "Confirmations": 3962. "Weight": 768. "Size": 192 bitgroups. "Status": Confirmed.
The transaction is confirmed, what's the issue? Confirmed means that the transaction is finalized. It has been confirmed for more than 3 weeks.
775  Bitcoin / Development & Technical Discussion / Re: Raw original work request of solved block on: January 13, 2018, 12:26:50 AM
Not just transaction ids, all of the parameters below
Coinbase1
ExtraNonce
ExtraNonce2
Coinbase2
Transaction Ids[]
Those parameters are part of the transaction ids. All of those parameters except for transaction Ids[] are for constructing the coinbase transaction. It's txid is then used in the merkle root.
776  Bitcoin / Development & Technical Discussion / Re: Raw original work request of solved block on: January 13, 2018, 12:14:38 AM
The merkle root is computed from the transaction ids.
777  Bitcoin / Bitcoin Technical Support / Re: Where is the hash of the genesis block in the Bitcoin code ? on: January 13, 2018, 12:07:26 AM
I don't find it, the "main.cpp" file doesn't exists anymore, I've looked for the Genesis Block hash in validation.cpp and net_processing.cpp but i don't find anything  Huh
It's in chainparams.cpp

By permission do you mean to be able to open the wallet?
Both read and write to the file. If you right click it and choose Properties, there should be a tab labeled Permissions or Security and there you can see whether your user has the permission to read and write to the file.

And would you be able to suggest what may have caused this condition to occur? The wallet on this client is encrypted and is on my own personal machine. I haven't attempted to open the wallet in months but I have access if needed.
Copying files from different machines can result in conflicting file permissions.

Could this be an attempt to open the wallet from someone connecting to my node?

Also, I did not think anything of it at the time because nothing seemed to happen but I did hook up a 21bitcoin computer to this computer about 4-5 days ago just to see if there was anything I could do with it but there did not seem to be any prompt or files I could see so I unplugged it and thought nothing more of it. Could it have begun to try to access the wallet because of the mining chip days later even if it wasn't connected anymore?
No.
779  Bitcoin / Bitcoin Technical Support / Re: What is the difference between a segwit address that starts with a 3 and a b? on: January 12, 2018, 11:58:34 PM
How can I make a vanity Bech32 address?
The same way you make a P2PKH vanity address (begins with a '1'); generate random private keys, calculate their public keys, hash the public keys, and encode it using bech32. You will need some software that can do that, but I don't know of any that currently exist.

Are there any guides you can link me?
No.
780  Bitcoin / Development & Technical Discussion / Re: Exactly How Do you Fork a Blockchain? on: January 12, 2018, 01:14:42 AM
You make a block that follows different consensus rules and is consensus incompatible with the current blockchain such that it will be rejected by nodes not running your software.
