3. Definition
A blockchain is an
immutable distributed
ledger that contains
cryptographically hashed
blocks of data stored in
chronological order and
used to record transactions
between parties

4. • Satoshi Nakamoto
• 2008 White Paper
• P2P digital currency
transactions
• Vitalik Buterin
• 2015 Launch
• Distributed Computing
• Smart Contract OS
• Linux Foundation
• 2017 Launch
• 5 Frameworks
• Enterprise Focus
History
Bitcoin – v1.0 Ethereum – v2.0 Hyperledger – v3.0

5. • Replication at every node
• Data stored is immutable
• Chronological by hashes
