Mysql is data base that records, inputs as a data base on your own personal Blockchain? Did you hear me? The QR Code below address is that fact!’ The words that followe this thought is reflected in the sha256 statement below this statement of fact……… The Qr Code below reflects That fact and that sha2566 signiture below as a crypto graphic hash on a “MYSQL data base as follow: :-)CKB

SHA256 Hash: 55539df0f43fbc93789ae5e2900ccda3fb5beca86b6c86daeaaf1d9f22fa7a8d
