I hereby claim:

  * I am an admin of http://mdzhang.com
  * I am mdzhang (https://keybase.io/mdzhang) on keybase.
  * I have a public key ASDNnkEnI34vSbc8M9SFBt40V9If62nPjkAwIIzH3KUDOAo

To do so, I am signing this object:

    },

  "seqno": 64,
  "tag": "signature"
}

which yields the signature:
