Attendee Question: In your opinion, what are some research areas needed for blockchain (other than security) ?
Answer (Toufi Saliba & Adam Gravitis): Scalability, Transaction Cost and Security: many blockchain systems rely on global consensus for their entire ledger and this doesn’t scale either bandwidth-wise or processing-wise. Currently one blockchain that I know of is working on all 3 combined in a Ledgerless distributed setting, it’s called Toda Protocol.
