The blockchain integrity is protected by Cryptographic hashing, key signature, and timestamping mechanisms.  Every change scheduled and addressed… Read more »

Lately, I don’t have the luxury of my big old machines at Oracle so I used my own free-tier account on AWS (Thank you AWS). I was able to quickly put… Read more »
