[Bitcoin-development] Why are we bleeding nodes?

Multi-sig requires infrastructure.  It isn't a magic wand that we can 
wave to make everyone secure.  The protocols and techniques necessary 
don't exist yet, and apparently no one has much of an incentive to 
create them.

I mean no offense, and I don't mean to pick on you.  Your post stuck out 
while I was reading.  Secure multi-sig is what we all want, but wanting 
apparently isn't enough to make it happen.

Other random notes from reading this 50+ post thread:

Perhaps we should have a config flag to prevent a node from serving IBD 
to new nodes.  IBD crushes marginal machines, particularly those with 
spinning disks.  This has been extensively discussed elsewhere.

The ideal IBD hosts are serving the blockchain out of a RAM disk. Is 
there any interest in setting up a network of volunteers to host 
expensive servers with fast connections?  It doesn't look too terribly 
difficult to figure out when a node has stopped asking for blocks in 
bulk, so we could add another config flag to eject nodes once they are 
done booting.

Even ignoring IBD, I think that we are gradually outgrowing cheapass 
hosting options.  Personally, I long ago gave up on answering forum 
questions about running nodes on virtual servers and VPSs.  It is 
certainly still possible to run bitcoind on small boxes, but it isn't 
trivial any more.  (Anyone running on less than my Athlon XP 1800+ with 
896 MB RAM?)  If we want those nodes back, we need to optimize the hell 
out of the memory use, and even that might not be enough.
