Abstract: Blockchains are the technology underlying the digital currencies Bitcoin and Etherium. The technology is being hyped for many different financial purposes from government issued digital currency to supply chains to identity management. 80% of banks are predicted to initiate blockchain projects by the end of this year and billions have been invested in blockchain startups.

Blockchains have appealing security and privacy characteristics. They are cryptographically secure and can support proofs of assertions such as “Person X has transferred $Y from account A to account B” without revealing the identity of person X, the amount of $Y, account A or account B.

All of this sounds much like “black magic”. In this talk, I will delve into the technology of blockchains from the perspective of a non-cryptographer and attempt to make the magic of blockchains less opaque.
