I want to connect to my btcd-server with javascript

Can I disable the RPC-CERTIFICATES or how can I connect with Javascript over TLS?

I just saw this. You can't disable TLS, but I have a gist up on my github which demonstrates how to connect via TLS that I've tested with firefox and chrome:

https://gist.github.com/davecgh/8a16b1048fe0fb406d29

Make sure you modify the username and password near the top of the file in the javascript to the correct values or you'll get an undefined error since btcd will immediately disconnect you upon receiving invalid credentials.

Can you subscribe to new unconfirmed transactions with btcd ?

Yes. See https://github.com/conformal/btcd/wiki/JSON-RPC-API#WSExtMethods. In particular the notifynewtransactions method.

like the blockchain API: https://blockchain.info/de/api/api_websocket

I currently use the blockchain API for my site: btcaudio.tk/live

but I want to use my own bitcoin node for this .. can I do this with btcd?

I recently switched from running bitcoind to btcd on linux.

Once golang was installed it’s pretty much an automated installation process – 1 command to auto download and install the btcd package. A well-documented sample config file is provided that was easy to tailor. Launched it and done.

Full network sync from scratch took 26 hours. Memory usage is in the 200MB range. Couple of days in it’s been rock solid and seems to be working great.

I’m hugely impressed with what the devs have achieved. Their code appears to be clean, modular, well documented and comprehensively covered by tests. So a great base to build on.

I've also recently tested btcd out, and the code looks clean + tests are present. I do see better performance than bitcoind, as well. Keep up the good work!

I'm not sure what point you're trying to make, but I think perhaps you are confused. The btcd code is ISC licensed and freely available for all to fork and modify as they see fit. It is no different than Bitcoin Core in that respect.

I am trying the new btcd v0.9.0-beta now .. https://github.com/conformal/btcd/releases

Would you please file an issue on the btcd issue tracker? We'll need to get your database logs to track down your issue.

I just built on Windows XP x86 AND Windows 8.1 x64 .. BUT the bug is STILL HERE !?

Is it normal that my new .exe builds are smaller than the "original" ones?
they are just 12 MB (x86) and 15MB (x64) big!
original x64 = 18MB

You'll need to delete your database from "%LOCALAPPDATA%\Btcd\data\mainnet", so the chain download starts over. The issue is your existing database is corrupt (hence why you're seeing the issue looking up a specific transaction), so only upgrading the code alone won't fix it. However, the root cause that led to the corruption to begin with is what updating the code resolves. I should have mentioned that in my original response.

As far as the size, the last released msi was built with the Go 1.2 runtime, and I'm guessing you built the latest with the most recent Go 1.3.1 run-time, so a difference in size is expected. 12MB (x86) and 15MB (x64) is what I have as well with the go 1.3 runtime.

EDIT:

I just rebuilt to verify:

x64
09/18/2014 10:13 AM 15,415,296 btcd.exe

x86
09/18/2014 10:15 AM 12,524,544 btcd.exe

thanks

my x64 build

EDIT: AFTER SOME HOURS I GET THE "Adding orphan blocks"-BUG AGAIN Angry

What is going on here? Is this a BUG?

There was a bug in the upstream leveldb that could rarely lead to what you're seeing and was fixed a while back. There hasn't been a new Windows msi released yet. You can build from source quite easily with Go on Windows if you want to build with the latest code.

There will be another msi release soon which includes that fix along with several other enhancements.

Very cool stuff! This is great news. What motivated the project?

maybe the competition from bitcoin.

What the actual status of this?

Does anyone of you using it as replacement (especially as simple full node without wallet functionality)?

I have used it as a successful drop-in replacement for bitcoind-ncurses. https://bitcointalksearch.org/topic/m.8190154 It is very nice having a unified interface so that I can monitor both simultaneously.

At least 13 or so:

I have used it for a while and if anything it seemed to use less memory.
