so last night I set up a cryptosteel

if you haven’t heard of them, they’re this metal cylindrical capsule where you slide steel tiles onto a rod inside to safeguard a seed phrase

yes, setting it up letter by letter was absurdly tedious

but DAMN does it feel hardcore once you’ve got the finished result in hand

And then part two- opupload that marbled blob into the blockchain to be able to find it anytime you want.  
You could travel the world with memorizing a keyword to find your blob, and a password to decrypt your blob. 
Decentralized
Trustless
Permanent
