I disagree with this comment. The way this is currently implemented is a mem
exhaustion dos in itself waiting to happen and does nothing to prevent
network flooding.

I agreed up to this point. Private keys should not be stored on nand. Please
look in to the data recovery clusterfuck nand creates when concerning
sensitive data.

It is close to impossible to reliably delete such data, moreso on usb keys
than ssd, short of absolute physical destruction and noone should be
recommending this. Ever.

If the caveat of a trusted third party is acceptable and, as greg mentioned,
if there was a way to export unsigned transactions and then import/broadcast
after signing this becomes fairly trivial.

Shamir's + 3rd party to combine and sign means no protocol level changes.

Process could work something like this:

Parties agree to endpoint destination address and provide it to third party.
Third party generates key and provides shares to each party in the txn and
the resulting address to both as well.
Third party destroys (preferably, never stores) private key.
Sender sends to address.
Both parties after confirmation of reciept of goods or what have you provide
shares back to third party who uses the privkey to xfer inputs to the
previously agreed upon destination subtracting their fee.

This resembles more traditional escrow setups and relies on the trust of a
third party, which is not ideal, but would be fairly simple to implement
until the other proposals could be better investigated and implemented.

🗒️ Summary of this message: The Bitcoin network is experiencing connectivity issues due to a lack of connectable slots. Sorting nodes by version could help resolve the problem.
📝 Original message:There's a bigger problem here honestly. The p2p network is just starved for
connectable slots.

You can start up a bitcoind, on a host with sufficient connectivity, with
-maxconnections=512 and they will fill in <15 minutes.

As to why sort by version: <=3.23 has problems serving the blocks from the
last 2 months. It can take days to weeks to get the whole chain if you're
connecting to those nodes.

To contribute:

I think the separated-from-github bounty system would be great. BUT:
The bounties need to go into some form of escrow. There have been way
to many bounties that weren't paid since BTC broke the $1USD boundary.

This would be true if gmake didn't build/run basically everywhere; but, it does.

Don't get me wrong, I'm not defending autotools' design or implementation. It is; however, more ubiquitous and understood by a much wider audience.

> BTW for cmake there is "ccmake" which is even better than configure --help as it offers an interactive interface for configuration.

I would say that's actually a mark against cmake. If you need a gui to select build options because your cli doesn't have proper help output something is wrong.

If you're willing to setup and maintain a cmake build environment I wouldn't say it should be rejected outright. Speculating about it without an implementation to compare seems like a waste of time.

Especially when jaromil already has a mostly-functional autotools setup. It needs tweaking still and some changes to catch up and rebase, but it works. He also already did the tedious work to rearrange the source tree to make adding any auto-configuration tool for the build environment easy to drop in place. (Which is already merged.)

📝 Original message:Cmake is just as bad as autotools, just with a different syntax and more "buzz" behind it right this second. I don't see any advantage to it over autotools unless you're not familiar with either and even then I wouldn't really call it an advantage. It's just different.

It also requires a dependency that isn't installed by default anywhere, as already mentioned, and is less known outside of some obscure qt/kde circles and so finding people who are familiar with it and are willing to maintain it is more difficult.

Autotools is the devil you know.

You'll probably throw out that mysql and compiz have switched to it, but really, those projects aren't something that should be emulated by anyone. Ever.

I don't think this should be a vote at all. Given Greg/Matt's numbers it is a necessity to ensure network stability over the next 90 days.

Also: the default will only apply to pre-built binaries, which bitcoind isn't one of, so for people running bitcoind this default doesn't matter at all. Just continue building without UPNP support as you're already doing.
