Update
I found a x509 certificate certified by W3.org
inside the paper There are many electronic signatures on this paper And next to this paper, there is Hash - but i cant open it - its need programe or something ealse !
This certificate refers to transactions UTXO !
With the research, I found that the blockchain deals with this company or organization

And I also found Backup Crypto folder inside keys name ------> Hash - sha1 - md5sha as it show on my last replay !
i am not sure but i think these keys for indroid and this is my backup !
The dates of these keys from 2010 and 2013

Any future update I will post it here
