Duplicated records: inefficient, slow
What happens if these records differ?
Shared Ledger: Append only, distributed
Privacy: Who can see or update what
Smart Contract: Business terms/rules embedded & automatically executed
Trust: Events & transactions are verified & endorsed
Blockchain – foundational technology, like the internet.
Many known concepts:
Distributed consensus – similar to distributed system consensus
Event processing - react to events, execute code stored in Smart contracts
Cryptographically signing – like JWT
Peer-2-Peer – like Torrent
