      Interesting problem: Build verifyable chain from PGP-signed git commit to each end user browser. Anyone working on that? @keonne @blockchain

      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 SSH is good model. Leave judging of "identity" & non-crypto integrity, which is dependent on local knowledge, up to users.

      @NickSzabo4 @jgarzik If, app signer as a brand, then we need a cryptographic signature over a concept. That I grok cf Ricardian contracts ;)

      @iang_fc @jgarzik Crypto protects syntax not wet semantics. Doesn't prevent trademark spoofing or phishing.

          @iang_fc @jgarzik Key holder can claim mappings from key to other info on block chain. Homestead syntactic brands, cf. Namecoin keys:names.

          @NickSzabo4 @jgarzik Right, we can do more- Keyholder claims mulitples, weld them to brand. Redundancy works, can't phish the blockchain.

          @iang_fc @jgarzik Spoof names by creating mental error (e.g. claim "Szaabo", user thinks it's me): crypto/block chain doesn't stop that.
