 We've dodged several emergency scale vulnerabilities by not having TLS.

I'm still trying to understand the original premise that we want
encrypted communications between nodes.

I can certainly see the value of having *authenticated* traffic with
specific nodes, using an HMAC for the protocol messages in place of the
current checksum.

Re: [Bitcoin-development] Stealth Addresses

 I'm very against the name reusable addresses and strongly belive we
 should stick with the name stealth addresses.

I agree wholeheartedly against using reusable address.  I personally
am fine with stealth address, but can see where there might be a
negative connotation.

Might I suggest master address, which is neutral in connotation, but
indicates both that it is fixed and that payment addresses are generated
as needed from it.

But please, no reusable address.

 Server provides a token for the client to sign.

Anyone else concerned about signing an arbitrary string?  Could be a
hash of $EVIL_DOCUMENT, no?  I'd want to XOR the string with my own
randomly generated nonce, sign that, then pass the nonce and the
signature back to the server for verification.

 Has everyone seen

 Bitcoin has its own ISO currency code.


My understanding is that XBT is a proposed standard, and hasn't been
approved by ISO yet.  Did that change?

 What about something like Cloudflare? Transparent to most and it'd help
 with your bandwidth issues.

By way of endorsement, at the GNU Radio Project we switched to
CloudFlare's free service tier a few months ago.  We host on AWS EC2 our
own web servers, downloads, and git repositories.  CloudFlare has
reduced our bandwidth bill by about 50%, with very little pain.
