PUBLIC LEDGER = PUBLIC DATA
Data is proof. Everything is stored. Is all this data good for us? What if certain data is never removed? What if all our interactions are kept, forever? Proof of work. Proof of stake. Proof of life, through data?
Who are we online? Who am I, who are you? Who knows us? Who tracks us? Is it allowed to be anonymous? Can we buy something privately online? Should we?
Exclude bad actors. What if someone misbehaves? How is your online reputation? Who decides? Should anyone ever get excluded? Permanently? Should blacklists exists?
AI and Robots. Should we embrace more decisions taken by algorithms. AI a blessing, or a threat? AI consumes data, will they ever have enough? What if we loose control and robots take over?
