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
