ZERO: The Zcash Revolution
How Privacy Became the Next Bitcoin
By Ryan Bethencourt
The definitive story of the cypherpunks, cryptographers, and idealists who built the world’s most private money.
About the Book
The story of Zcash is the story of privacy itself — the dream that financial transactions could be as private as a conversation whispered between friends.
ZERO traces this dream from the cypherpunk mailing lists of the 1990s through the invention of zero-knowledge proofs, the creation of Zcash, and the explosive governance battles that nearly destroyed it. It’s a story of brilliant cryptographers, stubborn idealists, and the inevitable tension between building revolutionary technology and the very human politics of the people who build it.
From David Chaum’s DigiCash to Zooko Wilcox’s vision, from the trusted setup ceremonies to the Halo 2 breakthrough that eliminated them, from the ECC governance crisis to ZODL’s $25 million resurrection — ZERO is the complete, inside story of how a group of mathematicians and cypherpunks built financial privacy for the digital age.
