      Take trusted JS browser code execution to the next level. If "binaries" have moved to the browser, code there must be signed.

      SSL is woefully inadequate against large classes of MITM. Chain from PGP-signed git commit (etc.) to browser much more secure.

      @jgarzik To make PGP better, need also a reliance statement: ie you rely on PGP to say what, exactly? Not MITM'd? Not malware? Not private?

      @iang_fc @jgarzik This signing, SSL or PGP, would provide integrity of the channel from the signed code to browser -- no more than that.

      @iang_fc @jgarzik Previous schemes "failed" because we added expectations crypto doesn't actually provide, e.g. "identity" of source.

      @NickSzabo4 @jgarzik users are rational, expect to rely on claims from "crypto". Without reliance, what's the point? What are we saying?

      @iang_fc @jgarzik Not silence: crypto protects the syntactic content. A positive, true, and important, if harder to communicate, claim.

      @NickSzabo4 @jgarzik If I sign over "I am when I semant" then I have to live or slide by the claim.

      @iang_fc @jgarzik "Live or die"? Who is going to kill you? Such wet semantics is motivated by human actions if at all: not by the crypto.
