BLOCKCHAIN
— An increasing list of records that are linked using
cryptography(Wikipedia).
— Eliminates “autocracy” and “Single point failure”.
— Confirms the ‘integrity’ of the network.
— Secures the “truth” and eliminating the “trust”
requirement.

BLOCKCHAIN
Abstract answer: a blockchain provides
• coordination between many parties,
• when there is no single trusted party
if trusted party exists ⇒ no need for a blockchain

The similarities of public and private blockchain
— Both are decentralized peer-to-peer
networks,
— Has append-only ledger of digitally
signed transactions.
— Both maintain the replicas in sync
through a protocol referred to as
consensus.
— Both provide certain guarantees on
the immutability of the ledger,
even when some participants are
faulty or malicious.
