2381  Bitcoin / Development & Technical Discussion / Re: Shouldn't address have "domains" (easy entry for normies) on: August 31, 2017, 02:41:18 PM
You could be using addresses, as you can still use IPs. So no problem about privacy. It could be more like "Name of my wallet, in which all my addresses are stored". Then you would be just giving other people your wallets ID.
That is not how Bitcoin works. The network has no concept of a "wallet". The network does not know nor does it care about what addresses are in your wallet. There is no such thing as a "wallet ID" to the network (or one that is consistent across multiple wallet implementations).
2382  Bitcoin / Development & Technical Discussion / Re: P2SH-P2WPKH (Segwit) change addresses in Bitcoin Core - how? on: August 31, 2017, 02:34:40 PM
1. make the wallet generate segwit change addresses by itself so that we can just use sendtoaddress and other RPC calls without workarounds (maybe an option in config?),
This is being worked on for the next version of Core (after 0.15.0). It will likely be a minor release.
2383  Bitcoin / Bitcoin Technical Support / Re: How to stay with legacy address format? on: August 31, 2017, 02:32:09 PM
-I see that bech32 addresses have bc1 at the beginning, is this the part that will always repeat to recognize the segwit transactions?
Yes. That is the human readable part of bech32 and will be the same for all bech32 addresses. Bech32 addresses are different from the legacy addresses (1.. and 3..) since it uses a different encoding.

-I also noticed that there isn't a single character with capital letters. How come there are no caps at all? Im used the classic format and seeing it all in small characters is pretty weird. Im not even sure of legacy format being caps sensitive, but I think it was easier to recognize the shape of the address if there are caps on and off or maybe that is how my brain works.
Bech32 uses a different encoding scheme which is case insensitive unlike the legacy address scheme which is case sensitive. Legacy addresses are encoded with base 58. However bech32 encodes things with base 32 which does not include any casing.

About caps sensitive.. what would happen if instead of 12sziC91z7hwfpVDNw7UbsisaapBwFtW7t you send BTC to 12szic91z7hwfpvdnw7ubsisaapbwftw7t ?
The address should be invalid. It is case sensitive, so that would be wrong.

-In the case of a split into a fork of BTC that doesn't support the segwit format... how would you receive your share?

For example if the BCH fork happened after segwit got activated and you were holding 1 BTC in address bc1qzjw3jywhf2r7k24y3gqj0fs4apddg03pujsjzx, how are you supposed to receive your 1 BCH on the other chain?
Since segwit has already activated, such a fork would result in you losing any and all money that is in a segwit output, both nested and native. This is because such a fork without segwit would regard all of those outputs as anyone-can-spend outputs and the miners who initiated that fork would steal all coins in segwit outputs and send them to themselves.

To actually spend those, for native outputs, you would just have an empty scriptSig and it would work. For P2SH nested ones, you would just put the redeemscript in the scriptSig and it would work. There would be no place for signatures to go.

Go to the Armory data directory (it should be C:\Users\Palazzeschi\AppData\Roaming\Armory) and delete the databases folder. Then start Armory. This will force it to build new databases and that should fix your problem.

Best library I've used so far is bitcoinj, it allows to query blockchain info you need without downloading it.
That's not true. It still has to download part of the blockchain and there is still a lot of info that you cannot get from it without downloading the entire blockchain. For example, you cannot use bitcoinj to find an arbitrary transaction in the blockchain since it does not have that data and it can't ask for that from a node.
2386  Bitcoin / Development & Technical Discussion / Re: Mempool size falling to 0 : what's going on ? on: August 31, 2017, 02:03:13 PM
That does not look natural. That is almost certainly because of problems that blockchain.info has. It doesn't match what other mempool chart sites like https://jochen-hoenicke.de/queue/#2d show.
2387  Bitcoin / Bitcoin Technical Support / Re: private keys in hexadecimal help on: August 31, 2017, 01:57:26 PM
Have you tried using Bitcoin Core's -salvagewallet option yet? Although -salvagewallet has a few issues, it should help if your wallet is corrupted. But before you do that, always make sure that you have a backup of your wallet somewhere.
2388  Bitcoin / Armory / Re: Armory Remains on Preparing Database after update on: August 31, 2017, 01:55:39 PM
I'm having the same problem as metal 5050 but in the Windows version  96.1.  It stays in Preparing Databases indefinitely.  All settings are standard--using Win10 Home.   I've tried uninstalling and reinstalling to no effect.  Tried all builds back to 93.3 but none work.   93.3 used to work but stopped a few weeks ago. 
I can see bitcoin core running in the background and it is up to date.
Any suggestions?
Many thanks.
First of all, don't hijack someone else's thread with your own problems.

Secondly, please post your log files.
2389  Bitcoin / Bitcoin Technical Support / Re: Will this confirm on: August 31, 2017, 01:10:25 AM
Should I increase the fee a little more
Only if you want to have it confirm faster.

and do you know why it say amount sent 0.
If you are sending the Bitcoin to yourself to an address in the same wallet, some wallets will say that because the Bitcoin is leaving your wallet (besides the transaction fee).

Can you post the transaction ID or an address you sent to so we can check how long the transaction should take to confirm?

If you sent it to a company, then it'll say 0 until it gets between about 3 and 10 confirmations.

If your fee is more than 10 satoshi per byte, use this accelerator: https://pool.viabtc.com/tools/txaccelerator/
If it isn't then it may be useful to boost it to that amount or ask a miner to do it for you.
Please actually read the OP before responding and look at the picture that he linked to. That picture contains enough details.
2390  Bitcoin / Bitcoin Technical Support / Re: Will this confirm on: August 31, 2017, 12:55:59 AM
Your transaction should confirm eventually, but it may take several days. You will probably need to rebroadcast the transaction every day or so to keep the network reminded that the transaction exists.
2391  Bitcoin / Bitcoin Technical Support / Re: No valid UPnP IGDs found on: August 31, 2017, 12:54:20 AM
The client just keeps trying to find a peer indefinitely and I'm not sure this is supposed to happen.
That is quite strange since I am able to connect to one of the IPs in your log that had a connection timeout. Are you sure that you don't have a firewall that is blocking connections to and from Bitcoin Core? You can try disabling UPnP, but I don't think that is a problem here.

It did produce a blk00000.dat file that is 16777216 bytes whihc is quite strage if there are no connections over the network?
That's from Bitcoin Core allocating space for blk00000.dat and inserting the genesis block into it.
2392  Bitcoin / Bitcoin Technical Support / Re: No valid UPnP IGDs found on: August 31, 2017, 12:02:14 AM
EDIT: after loading up bitcoin core and doing a couple of google searches on some unfamiliar IPs I was previously connected to, I found that the number of connections have increased by a very large amount. It went from 6 to 4 to 56 connections.
That normally happens when you start a browser. It tends to connect to many things on the internet.

Have you tried doing a full resync? You can see if that will do anything before actually resyncing by renaming the datadir to something else and letting it make a new one. If it is able to establish connections, this means that something is corrupted in your block files, the block index, or the chainstate that is making it unable to connect, although I don't see anything in the log that indicates that that is happening.
2393  Bitcoin / Bitcoin Technical Support / Re: No valid UPnP IGDs found on: August 30, 2017, 11:25:12 PM
The TOR browser I have installed has a problem connecting to its own control port if that's useful information. I made a new tor browser that functions perfectly if there's a way to get that to override connections sent to the other tor browser?
Or a way for it to not need the tor control port as I don't think it's used anyway.
I don't think that matters.

Is TOR running? If so, what happens if you stop it and then run Core?

Start with the -debug option and post the full debug.log from that (it may be very large).

Lovely. Still I'm perplexed as to why this topic cannot be hidden/deleted as I'm perfectly sure SMF can do that.
The forum does not moderate scams or scam accusations. Topics will not be deleted or moved to the trashcan for being misleading, being a scam, or anything else. The only reasons for a thread's removal is for violating any forum rules which do not have anything pertaining to scams or scam accusations. They only pertain to posting behavior (i.e. spamming, off topicness, duplicate threads, etc.), and those are the only things which will be moderated.
2397  Bitcoin / Armory / Re: Armory 0.96.2 is out (SegWit enabled) on: August 30, 2017, 03:09:30 PM
is there a way to adjust the fee manually?
You can click on the Fee in the send dialog and a new dialog should appear that allows you to set the transaction fee.
2398  Bitcoin / Development & Technical Discussion / Re: Generating a large number of safe bitcoin vanity addresses on: August 30, 2017, 03:05:52 PM
I know, it is what I meant to say. I just assumed that like in RSA keys, if you start with one public key and change just the exponent of it in order to change the hash, then it's private keys of all of these new keys would have the same factors and be able to calculate the private exponent for all these public keys.
Assuming that during key generation factors are not discarded and just private exponent kept.
I made a lot of assumptions here based on my understanding of RSA keys and how you could generate different hashes for public keys with same module by just changing the public exponent, so that the owner of private keys could generate a private exponent corresponding to the new public exponent. I assumed it is a similar process and that all of these public keys would be (visibly) connected in such a way. Am I correct?
No, ECDSA keys are not like RSA keys. You can't do that to ECDSA keys.

How many wallet.dat files can you manage at the same time?
As many as you want.

What is the difference between using the native segwit format (that begins with b) from the one that begins with 3?
Is it just a temporal way to use segwit until the ones that begin with b are available or there are any pros and cons?
Native segwit addresses (bech32) make native segwit outputs which are smaller than the P2SH nested ones (3.. addresses). This saves you 22 bytes when you go to spend the output.
