[Bitcoin-development] State of Bitcoin Development: October Brain Dump

In the spirit of open communication, I thought I'd try doing a monthly
"what's up" with bitcoin development. Here's what's on my radar:
• Wladimir agreed to help pull patches, especially Qt-GUI-related
patches, and is now part of the core dev team (Wladimir did the bulk
of the work on the new Qt-based GUI).
• Matt and Wladimir will be working on 0.5 release candidate 1
binaries and an updated release process to either ship the Qt
libraries or statically link against Qt; the goal is to have them
ready this weekend.
• Network stability and wallet security are still my top concerns;
start-up experience for new users (the long wait to download the block
chain) is next on my list.
• Amir's Bitcoin Improvement Process proposal hasn't been getting the
attention it deserves; I'm just as guilty as anybody, I suppose we're
all very busy. Helping improve it and writing some BIPs is high on my
• I've setup a public-write-only
bitcoin-security at lists.sourceforge.net mailing list to be used as an
official way to report and then discuss potential security or
denial-of-service vulnerabilities in the bitcoin protocol, and invited
the following people to participate: Amir Taaki, Mike Hearn, Stefan
Thomas, Nils Schneider, Pieter Wuille, Jeff Garzi and myself.
Stuff I've been working on or plan to be working on soon; let me know
if you are able to take on any of these, there are too many things on
my TODO list:
• Implementing/experimenting: multi-signature transactions and using
OP_EVAL and a new type of bitcoin address to create 'always secure' or
'always backed up' wallets.
• Write BIPs proposing: OP_EVAL. 'standard' multi-signature
transactions. Maybe an informational BIP proposing how to roll out
upgrades in general.
• Denial-of-service detection/prevention (see the DoSorphans pull
request). It would be really nice if somebody with experience
simulating network behavior would take this over...
• Cross-platform testing infrastructure. I've made good progress on a
Twisted-based tool, but still have a lot to do.
• Tighten up block-time rules to fix the potential "timejacking" attack.
• Work on 'discouraging' blocks/transactions to punish
bad-for-the-common-good-but-good-for-me behaviors from miners or
• Get back to work on headers-only-for-initial-download, so initial
startup experience is better for people.
• Rethink/rework transaction fees; give both miners and clients more
flexibility to create a market instead of magic hard-coded constants.
• Organization; many things would be much easier if there was a
non-profit organization like the Tor Project to pay core developers,
testers, a PR person, pay for the Jenkins nightly build server, etc
