[ANN] BitEN - bitcoin erlang node

[aantonop]

Bite  BITcoin Erlang

BED = Bitcoin Erlang Daemon, nice and simple.
Usage: "Hey Carla, we're running "BED", are you using bitcoin-js at your startup?"


BITTEN : BITcoin Erlang Node

without acronyms:

The Bitscale Node - Makes Bitcoin Scale


CoinOTP

[uuidman]

Maybe the name Erlnode

[r.willis]

I really like BITTEN/BITEN. Release is coming.
Can anybody check 198.23.147.4:8333 and tell me if tx relaying works ok?
After handshake, host wll notify peers with inv and respond to getdata (type 1 (tx) only).

you should group your invs to improve anonymity and save bandwidth. only sending a inv once a 5 second.

[r.willis]

Thanks for testing. Can you also test if getdata works properly with transasctions?
Also, can you explain about inv and anonymity? For now I send inv to all peers when I get new tx.

i don't know, think its only meaningful to do it when you are also sending your own transactions, blending you own in with others.

the satoshi client sends them in groups.

getdata seems to work fine.

[r.willis]

Thank you for your support.
Please check how it works yourself. There is no documentation (and almost no comments), no tests.
There are some lurking bugs, but it mostly works. Codebase is really small (~1000 lines + ~500 lines SHA2 by third-party), so do not expect much.
Some tunable parameters (build-time) in include/config.erl
$ git clone git://github.com/r-willis/biten.git
than check README for instructions.
UPD: here is one-liner for updating stats every 10 sec:
3> T1 = timer:apply_interval(10*1000, stat, print, []).

[kokjo]

Awesome! code perving now.

[yoniassia]

You should check twitcoin.net also implemented a bitcoin wallet in erlang

[r.willis]

Thanks for the link, I'll check it.

no it does not, in only interfaces with bitcoind

[r.willis]

So, anyone tried it? Does it even work for you?

[kokjo]

So, anyone tried it? Does it even work for you?

no, i have exams. if i begin playing with bitten, i gonna fail them...

[r.willis]

Good luck with your exams.
It seems like there are some malicious nodes on the network, which send thousands of inv messages. As biten have no anti-DoS features, it causes memory exhaustion and erlang VM termination. I hope to push quick-fix today.

P.S. I decided to drop extra "T" from name, so it's biten.

EDIT: pushed some fixes and improvements.
Next: download block headers and organize them into trees.

Good luck with your exams.

they are not malicious, just stress testing the network.

I'm meeting a real ErlangOTP *expert* (phds, patents, the whole 9)  next week who recently got interested in bitcoin. Perfect timing to introduce your code...

[r.willis]

Do not think he will be impressed - it's my first "real" OTP project. I hope it will be able to run more than 24h without problems - right now after 2-3 hours it terminates.
