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
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
Centralized System of Record
