Re: <nettime> Josh Hall: Blockchain could reshape our world and the far right is one step ahead (Guardian)

I regret to be this anal - nettime is not (that) technical forum, but in 
this case blockchain has has nothing to do with securing IoT 
communications. At best, blockchain can provide authentication (ie. 
public key tied to identity), with properly expensive PoW, which is not 
the case here.

This reminds me that there is one sensible use of blockchain: public key 
directory. Too bad no one uses PGP any more.

Which brings me to another really interesting question: why don't DNS 
CAs use blockchains for storing certificate chains, instead of burning 
them into browsers via custom deals with multiple browser peddlers?
