If you give me the steps to build from source using python, I'll give that a whirl.
To run from source, first download and install python from There's a section where it says something about adding python to your PATH, make sure you choose that option.

Downlaod and extract protoc from There should be a file named protoc.exe in the bin folder.

Download the code from Copy protoc.exe from the previous step into the folder containing the source code.

Open up a command prompt or powershell in the folder with the source code. Then run the following commands:
python install
protoc.exe --proto_path=./ --python_out=./ ./paymentrequest.proto

Then run the cli program using

or the gui program using

If you don't use Segwit or Armory's P2SH-P2PK address options (may not be present in 0.96), Then there will be no incompatibility.
743  Bitcoin / Development & Technical Discussion / Re: How will Lightning Network be encouraged to use? on: January 17, 2018, 03:56:03 AM
there is no ETA. lightning developers have taken the position that there is "no rush" considering how much value is expected to be stored in payment channels. they are very concerned about ensuring that no funds are lost as a result of using the LN protocol.

having said that, it's pretty widely expected that LN will be usable by the general public sometime this year, likely in a matter of months. the next major step is to complete wallet implementations. we're already seeing lightning transactions on the network; now it's mainly just a matter of releasing the software.
It's not like there's an actual "official LN launch" date or anything like that. Rather LN will be "launched" when people feel confident enough in one or more implementations of LN to use it on the main Bitcoin network. In fact, you could consider LN to already be launched as there already are people using LN on the mainnet. Of course those people do so at the risk of their money, but nonetheless, the software mostly works and there are transactions occurring.

I wonder how a Lightning user interface would look like. Instead a "Send" button there will be "Open channel" button (same fee as just Send button + X bitcoins to deposit into channel) and then "Send via the opened channel" (no fee) and then "Close channel" (same fee as just Send button). Given this complexity and the fact that you have to spend twice as much in fees to send same amount of money as without LN I really wonder how the "greed" would work.
It's very likely that it will still just be a "Send" button. Channel management and all that will actually be handled by the software automatically. You put money into your LN wallet, and it will use that to open and close channels automatically. So when you want to send Bitcoin to someone, your LN wallet will have established several channels. It will also determine an optimal route and do everything automatically for you. There's no need for you to manually open and close channels yourself; the software will handle all of that for you.

Installed both vc_redist.x64&86 versions on windows 10 machine.  Same popup error when launching by double click and command line.  But when launching from command line, after closing the popup error message I get this in command line:

Error loading Python DLL 'C:\Users\@@@@\AppData\local\Temp\_MEI14242\python36.dll'.
LoadLibrary:  The parameter is incorrect
Yeah... I'm not sure what's wrong there. This is my first time using pyinstaller to generate binaries.
745  Bitcoin / Bitcoin Technical Support / Re: BitcoinCore node crashing on: January 16, 2018, 11:14:36 PM
Now though when I run bitcoin-qt everything is as it should be for approx 40-50 min's until it crashes. I could probably even send the little bitcoin I have in that wallet out to somewhere else if the mining fee wasn't as high as it is. But then again I wonder what might happen if that transaction didn't confirm within the 40-50 min window before my node crashed again. But other than that it syncs up and then connects to approx 8 inbounds and 8 outbound peers at the beginning, shows my balance and runs properly for about 45mins then gives the fatal internal error. The wallet dat file is encrypted but is in the bitcoin folder and I have checked that my user has read and write access.
So the wallet is from your local computer and not the 21 raspi? If so, the raspi is completely irrelevant to this discussion.

I read back thru the debug file to the 7th of this month which I believe is when I tried to connect the 21 pi and found a line in there that said "possible stale tip detected" I'm not sure what that means
It means nothing. That error is benign.

but it occurs to me that I only put a days worth of the debug log file in the Pastebin would it be more helpful if I loaded more of the debug file?
746  Bitcoin / Bitcoin Technical Support / Re: Segwit question on: January 16, 2018, 11:10:38 PM
Very nice. Do you have a screenshot that shows how different wallets will be managed? I mean how the GUI will look like? im curious about that since im used to always using the same wallet with Core. How will the different wallet files be managed? I mean how the filenames will look like if they are all on the same folder? wallet001.dat, wallet.002.dat... or something?
There are no different wallets or wallet files. If you use Bitcoin Core 0.16+, your wallet will automatically begin using segwit unless you tell it not to by setting the addresstype option to legacy.

748  Bitcoin / Bitcoin Technical Support / Re: [POLL] How long to sync on an initial core install on: January 16, 2018, 06:57:28 AM
It will sync faster and have less disk I/O if you increase the dbcache. This requires more RAM though. Raising the dbcache to anything larger than 8000 MB (-dbcache=8000 is large enough to store the whole thing in memory and then flush right at the end so there's significantly less disk I/O then. Of course you will need plenty of RAM in order to set the dbcache to that high.

I can work with I have, but would rather have it working on my windows 10 machine since that is where my Armory wallet is running.
I then went over to my windows 10 machine and tried btcpp-cli-win64 and this is the error I got:

btcpp-cli-win64.exe - Bad Image

is either not designed to run on Windows or it cointains an error.  Try
installing the program again using the original installation media or contact your system administrator or the software vendor or support.
Error Status 0xc000000d
Try installing the Visual C++ Redistributable available here: That should hopefully add the VCRUNTIME140.dll it wants to your system.
750  Bitcoin / Bitcoin Technical Support / Re: Why do not all exchanges offer transaction batching? on: January 16, 2018, 03:47:42 AM
  Some people are asking for Gemini do this. And I see that is not so common. I know that batching transaction will be slower. But there are other problems for exchanges do this? Is there any risk?
It's mostly just slightly harder to implement. There's also a privacy risk because the receivers in that batch can see how much money everyone else in the batch is withdrawing, but they don't really know who those people are, so that's not much of an issue.

Oops, I screwed up the build. I uploaded new builds (replacing the old ones), try those.
752  Bitcoin / Bitcoin Technical Support / Re: Segwit question on: January 16, 2018, 02:06:23 AM
The thing is, I don't feel confident using segwit until at least May when Core will release 0.16
Bitcoin Core 0.16.0 will be released sooner than May. It will probably be released in February as we are already in the feature freeze stage since the segwit wallet PR has already been merged.

755  Bitcoin / Armory / Re: help with achow101-payment-proto-interface on: January 16, 2018, 01:58:28 AM
I downloaded btcpp-cli-win64 this time.  Norton didn't like and removed, so restored and gave it trust in file insight.  Double clicked it and launched fine.  Created invoice for bitpay, and on invoice clicked copy to reveal the uri.  Copied uri from invoice, but wouldn't let me paste into the tool---so typed it.  When i hit enter the tool closed.  

That is the furthest i've gotten on any of my attempts.  I didn't get error msg, or crash report, but if you tell me where to look, i'll find it then post.
Open up a command prompt or powershell in the folder containing btcpp-cli-win64 (with nothing in the folder selected, hold shift then right click, choose "Open command prompt" or "Open powershell"). Type btcpp-cli-win64 to run the program from there. Follow the instructions, and if it fails, post the output. There should be a python traceback if it fails.

I'm on my windows 7, I downloaded btcpp-qt-win64, I went to norton file insight and trusted it and double clicked to launch.  rather than opening, it hung and i got the windows message to close program or look online for solution.  I didn't get the error message like i had been, but here are the details from crash report:

757  Bitcoin / Alternative clients / Re: Created TREZOR address with Ledger nano S ...problem on: January 15, 2018, 11:11:08 PM

Here. I mistakenly selected TREZOR and at the botom wre displayed trezor addresses and I put all my tokens in TREZOR adress, instead I should click the LEDGER and deposit in Ledger addresses. And now cant withdraw you know how?
Those are not TREZOR addresses but rather addresses using a derivation path that is default for the TREZOR. Since it is just a derivation path, your ledger can sign for those keys. You just need to tell your wallet software that you are using a Ledger and that the derivation path is m/44'/61'/0'/0 instead of the Ledger default.
758  Bitcoin / Alternative clients / 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?
759  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.
