Bitcoin
• Released in 2009 via a niche mailing list
• Now world’s largest digital currency
• Six hundred trillion SHA256 computations
performed per second
• Worth over $1k per bitcoin – 24,000%
growth since launch
• Buy pretty much anything

3.
Blockchain: What’s Special?
• Decentralized database maintaining a
growing list of records
• Peer-to-peer – not owned by a single
instance
• Any member can add it (if other
participants agree)
• State is distributed to all nodes
• Immutable, tamper-proof
• Trusted transfer of assets, value &
ownership
