[Bitcoin-development] Signature Blocks and URI Sign Requests

I don't think it's minimally invasive to layer PGP's web of trust on top of
Bitcoin, in fact, the opposite.

>From a certain angle, bitcoin exists as a sort of answer / alternate
solution to the web of trust. Digital cash with an existing web of trust in
place was a working concept in the mid-1990s, courtesy of David Chaum, I
believe.

I totally agree on the kitchen sink concern; I would personally like to see
something like a one-year required discussion period on all non-security
changes proposed to the blockchain protocol. We know almost nothing about
how bitcoin will be used over the next 20 years; I believe it's a mistake
to bulk up the protocol too rapidly right now.

There's a famous phrase from the founder of Lotus about Lotus' engineering
process: "add lightness." The equivalent for protocol design might be "add
simplicity." I'd like to see us adding simplicity for now, getting a core
set of tests together for alternate implementations like libbitcoin, and
thinking hard about the dangers of cruft over a 10+ year period when it
comes to a technology which will necessarily include a complete history of
every crufty decision embodied in transaction histories.
