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
