Remember, ignorance is bliss!

Thanks for your opinion, I hope I didn't start any "currency wars" in this channel :|.

I don't think it would be difficult to create an alt-coin version of Electrum.
I do not want to be involved in that for the moment.

Important notice for the users of the server electrum.novit.ro.

One of the disks decided to resign from duty last night, hard-locking the machine (so I guess I wasn't treating it nice enough...). The admins in the datacenter had to take the disk out and reboot the machine. This probably happened when Electrum was updating the database, because the db was full of errors after I resynced the RAID matrix and restarted all services. Right now electrum.novit.ro is rebuilding the database, so don't worry if your balance is zero - the blocks are not up to date at the moment. ETA ~48 hours (yeah, I know...), you should use ecdsa.org for the moment.

Sorry for this! I blame it on the Grinch.

That's not what I meant, I meant having multiple chains in one app simultaneously.

Actually now that I think about it again, this wouldn't have to concern the protocol at all, one could just use different urls for each chain.

So: nevermind.

I like namecoin, but it has different use cases than bitcoin and so a thin client isn't really useful.  The rest of the alt-chains are scams or not that useful.  I thought I might like litecoin, but it seems to be a waste of electricity.  Let's get electrum working.  By then the alt-chains we are talking about today will probably be dead and so implementing them will just be wasted time.  Keeping our eye on a modular app design is important though.


Having to install pygtk on my mac was a bit of work and won't ever be available on my iPhone, so electrum's ease-of-use is less than I would prefer.  Is there interest in a web-based electrum client?  It could store your private keys (that aren't deterministic) in local storage like GLBSE does.  I'm a web developer, I haven't done much work with desktop GUIs, and I want to help this project so a website is where I can help. If we had a simple webapp we could use phonegap and really easily have electrum clients on every major smartphone.

Contest - 2 BTC for suggesting a name of overlay network on top of Bitcoin

I also created separate discussion thread for my proposal/implementation, to keep Electrum discussion related to Electrum client itself: https://bitcointalk.org/index.php?topic=55842.0

If you want to run your own server, I wrote a simple (well, not so simple...) howto. Until it's merged into the main Electrum tree, you can read it here:

https://gitorious.org/~ovidiusoft/electrum/ovidiusofts-electrum/blobs/master/server/HOWTO

Suggestions, corrections, rotten tomatoes via PM or email, please.

Hi 2112, can you please move your post to https://bitcointalk.org/index.php?topic=55842.0 to keep this thread more about client than about protocol proposal? I'd like to reply to your post there.

I'm setting up an electrum server right now.  I plan on also running it with a tor hidden service just for fun.

Built a VM with 4GB of RAM and 4 cores of an Intel Xeon X5355 @ 2.66GHz. We'll see how long abe takes to run.  6 minutes got it to about "block_tx 822 840"

So far there have been lots of steps, but ovidiusoft's guide has helped a lot.  It doesn't mention anything about dependencies, but those will vary from system to system so thats okay.

I would like to have these included in the HOWTO. Can you please document it?

Everything was already installed on that machine (it's a test/development machine so I have a loooot of stuff there). If you're installing on a standard server distribution, let me know what packages are not installed by default so I'll include them in the HOWTO.

So while abe was indexing all of the blocks, I came across http://bitcoinjs.org/. For the last few months I keep flip-flopping between node and python.  As a webdeveloper, I pretty much have to use javascript, so node is very appealing to me.

As much as I love python and the ideas of electrum, I think I am going to work on my phonegap thin-client using bitcoinjs instead of electrum as the server.  I'm still going to run an electrum server, but it looks like my coding efforts will go elsewhere.

block_tx 31386 31603 after just over 3 hours.  My VM host was acting up for a bit and not giving the guest it's full CPU, but it seems to have sped up now.

sorry for off-topic. I switched to postgres due to mysql performance-issues. it _is_ faster (in the bitcoin-abe case at least)

Well I was wanting an excuse to play with postgres, but I think right now is in the middle of too many other things.  For now, my server is still running at max load with mysql.

When I do get it up, it will be at electrum.stitthappens.com (might as well change redemerald to my real name now :p ) and the hidden service will be at esvua6k2gzjj64ad.onion

Two weeks ago I installed Abe to one of my VPS because of running Electrum server. Although it's quadcore Xeon, it has poor I/O performance, so initial indexing took around four days. Few days ago, my database crashed and Abe turned into inconsistent state for some reason, which forced me to reindex whole blockchain (=another four days of waiting) again.

Because of such experience, I decided to provide a MySQL dump of Abe to public, as a torrent file. If you want to install Abe, feel free to download following file, it's clean blockchain index up to block 160095:  http://mining.bitcoin.cz/media/download/abe-160095.sql.gz.torrent . You can also help me seeding the file, of course Wink

Well I'm having troubles.

Code:
$ bitcoind getinfo

    "balance" : 0.00000000,
    "blocks" : 160203,

    "generate" : false,

    "hashespersec" : 0,
    "testnet" : false,
    "keypoololdest" : 1325056151,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "errors" : ""
}
$ electrum-server
starting Electrum server

No handlers could be found for logger "Abe.DataStore"
Enter username for jsonrpc at localhost:8332: bitcoinrpcusername
Enter password for bitcoinrpcusername in jsonrpc at localhost:8332:
Enter username for jsonrpc at localhost:8332: bitcoinrpcusername

Any ideas? I have the username and password set in /etc/electrum.conf so I'm not sure why it's prompting me for them.  When I put them in, it just prompts me for them again.

Any extra leading/trailing spaces in bitcoin.conf or electrum.conf ? Did you edit the files in Windows (so there might be a CR/LF there) ?

There are no trailing spaces and these files have never touched windows.  I don't see why that would even matter at all.

Do other people have the "Abe.DataStore" error?
