As you may know, I've recently moved to Puerto Rico with my family to enjoy this warm, beautiful island and its equally warm culture and people. As of Dec 4th, 2018, we are full-time residents of Caguas, Puerto Rico and so far we love it! We've already been on some beautiful hikes as well.
As part of this transition, I've created a new corporate entity here in Puerto Rico, Stokes Enterprises, LLC for all my consulting, advising, and service work in the cryptocurrency space. My friend 
To keep track of ownership transfer from my self as an individual to Stokes Enterprises, LLC, traditionally someone might mail themselves a signed, certified letter or pay for a notary to witness the document signing. Thankfully, I've got a blockchain. :)
I wrote up a few ownership transfer documents for the blockchain related services I currently export (Steem witnessing and education/training/content, EOS development via eosDAC worker proposals, and SmartCash infrastructure with Smart Nodes), printed them, signed them, and then scanned them to pdf using Genius Scan on my phone. I then used the shasum command on my computer to get a cryptographic hash of the signed documents like so:
➜ shasum steem_account_ownership_transfer_signed.pdf
873045b8fe2db0af4b63d768556cc83777f93712 steem_account_ownership_transfer_signed.pdf
➜ shasum eos_account_ownership_transfer_signed.pdf
fb22e3bff075007f4ed708816fc8b65de6549b1e eos_account_ownership_transfer_signed.pdf
➜ shasum smartcash_ownership_transfer_signed.pdf
de08195513756f3929e2a1519386e8e5b2cde0b7 smartcash_ownership_transfer_signed.pdf
If I really wanted to, I could go the extra step and store the entire file on the blockchain as an encrypted, signed GPG file as I've done before: Securely Storing Data Backups on the STEEM Blockchain but that might be a bit much for this.
Just by posting this blog entry on the Steem blockchain with these hash values, I'll have verifiable proof that these documents existed at this time.
Pretty cool, right?
